Abstract
BACKGROUND Mercury chloride (HgCl2) damages tissues it comes in contact with in sufficient concentration. This study evaluated the protective effects of n-butanol fraction of Phoenix dactylifera (BFPD) on mercury-triggered liver toxicity in Wistar rats. 25 male rats were divided into 5 groups of 5 rats each. Group I was administered 2 ml/kg of distilled water; group II was administered 5 mg/kg of HgCl2; group III was administered 500 mg/kg of BFPD + 5 mg/kg of HgCl2; group IV was administered 1000 mg/kg of BFPD + 5 mg/kg of HgCl2, while group V was administered 100 mg/kg of silymarin + 5 mg/kg of HgCl2. orally for 2 weeks. The rats were euthanized and liver tissue blood samples were collected for histological, histochemical, stereological, immunohistochemical, molecular, and biochemical studies. RESULTS The results revealed that HgCl2 induced oxidative stress in the rats evident by histoarchitectural distortions and altered levels of liver enzymes, proteins, and oxidative stress biomarkers when compared to the control. However, BFPD treatment restored these changes. Glutathione peroxidase levels decreased (p < 0.05) in the HgCl2-treated group when compared to the control and BFPD-treated groups. HgCl2 group revealed reduced reactivity with histochemical and immunohistochemical stains (Masson's Trichrome and B cell Lymphoma 2) when compared to the control, with a significant decrease in quantified liver Bcl-2 stain intensity when compared to the silymarin-treated group. BFPD administration revealed normal staining intensity comparable to the control. HgCl2 administration revealed a remarked decrease in the number of hepatocytes when compared to the control, BFPD, and silymarin groups. BFPD preserved (p < 0.05) the stereological features when compared to the HgCl2-treated group. GPx activity in the liver decreased (p < 0.05) with HgCl2 administration when compared to the control and silymarin-treated groups. BFPD attenuated GPx gene activity to levels similar to the control indicating some level of amelioration against HgCl2-induced toxicity. CONCLUSIONS The ability of BFPD to mitigate HgCl2 triggered liver alterations could be attributed to the antioxidant property of its flavonoid content. Therefore, BFPD may be a potential candidate for treating and managing liver-induced mercury intoxication.

Abstract
BACKGROUND In the current World Health Organization classification, acinic cell carcinoma (AcCC) of the breast is considered a rare histological subtype of triple-negative breast cancer. Because of the few reports in the literature, data concerning clinical outcomes are limited. Here, we report a case of AcCC of the breast in a 48-year-old woman. CASE SUMMARY A 48-year-old woman with a mass in her right breast came to our hospital for further diagnosis. Mammography and an ultrasound (US) scan showed a mass in the upper inner side of the right breast. She then underwent surgery to resect the mass in her right breast. Postoperative pathological examination revealed that the tumor had abundant acinar-like structures formed by tumor cells with prominent eosinophilic granules in the cytoplasm, consistent with acinar cell carcinoma. The results of immunohistochemical analysis supported the diagnosis of breast acinar cell carcinoma. Two months later, she underwent breast-conserving surgery and sentinel lymph node biopsy. The pTNM stage was T2N0M0. After surgery, the patient received 30 radiotherapy sessions. The patient was followed up for a period of one year, and no recurrence was found. CONCLUSION AcCC of the breast is a rare type of malignant tumor. Because it is usually asymptomatic and can be detected by imaging studies, routine breast US or mammograms are important. However, there are no characteristic diagnostic imaging findings or clinical manifestations, so immunohistochemical examination is critical for an accurate diagnosis of AcCC of the breast.

Abstract
BACKGROUND Adenoid cystic carcinoma (AdCC) is considered one of the most common destructive types of malignant salivary gland tumor that have high affinity to perineural invasion (PNI). This study was conducted to access different histological features of AdCC, and assessment of the immunohistochemical expression of CDC-7. METHODS Thirty formalin-fixed paraffin incorporated tissue blocks of AdCC were classified according to the WHO histopathological types. The immune-expression of CDC-7 positive area was evaluated according to percentage area as following: Negative = 0 %, Weak = 1-10 %, Moderate = 11-49 %, and Strong = 50-100. The correlations between expression of the marker and different clinico-pathological variables were investigated using Chi-square (χ2) test. The P-value ≤ 0.05 was considered statistically significant. RESULTS The expression of CDC-7 revealed statistical significant difference between the different tumor types (p ≤ 0.05). CONCLUSION The biological behavior of AdCC can be predicated from the expression of CDC-7.

Abstract
Introduction The most widespread female malignancy is breast cancer (BC), considerable percentage of patients with triple-negative BC (TNBC) experience rapid progression, recurrence, and metastasis. BC has not historically been treated as an immunogenic cancer. Nonetheless, several researchers have started to concentrate on immunotherapy. Aim The aim of the study is to investigate the immunohistochemical (IHC) expression of programmed death-ligand 1 (PD-L1) by stromal tumor-infiltrating lymphocytes (TILs) and tumor cells (TC) in female (TNBC) and to correlate with pathological features of such tumors, particularly those determine biologic behavior, such as the grade and stage the overall survival. Methodology This is a retrospective study which includes 49 paraffin-embedded tumor tissue sections which were collected from breast surgery specimens either radical or conservative of female patients with TNBC. The samples were analyzed immunohistochemically for PD-L1 expression. Results There were statistically significant relations among TC PD-L1 expression and TILs PD-L1 expression as well as relations among TILs PD-L1 expression with histologic grade, stromal TILs, and Ki-67 were statistically significant. Correlations between TC PD-L1 expression and N stage, histologic grade, and anatomic stage were statistically significant. Improved survival was detected within TILs PD-L1-positive cases; however, the correlation between the overall survival and PD-L1 expression in both TCs and stromal TIL was not statistically significant. Conclusion PD-L1 expressed in tumors with poor prognostic features such as the high grade, advanced T stage, and high Ki-67 index, TILs PD-L1-positive cases experienced improved survival supporting its prognostic significance. However, the correlation with overall survival was not statistically significant.

Abstract
PURPOSE Transglutaminase 2 (TG2) is associated with mobilization, invasion, and chemoresistance of tumor cells. We aimed to determine whether the immunohistochemical staining with TG2 antibody differs between metastatic and non-metastatic papillary thyroid cancer patients. METHODS We included 76 patients with papillary thyroid cancer (72% female, median age 52 (24-81) years, follow-up time 107 (60-216) months). Thirty of them with no metastasis, 30 of them with only lymph node metastasis and 16 patients with distant ± lymph node metastasis. Immunohistochemical staining of TG2 antibody was evaluated in the primary tumor and extra-tumoral tissue. We also divided subjects into two groups according to their primary tumor TG2 staining score (group A, high risk group: ≥3, n = 43; group B, low risk group: <3, n = 33). RESULTS Vascular invasion (p < 0.001), thyroid capsule invasion (p < 0.001), extrathyroidal extension (p < 0.001), intrathyroidal dissemination (p = 0.001), lymph node metastasis (p < 0.001), presence of aggressive histology (p < 0.001) were significantly higher in group A. No significant difference was found between the groups in terms of distant metastasis. Based on ATA risk classification 95.5% of patients with low risk were in group B but 86.8% of intermediate risk and 56.3% of high risk were in group A. In regression analysis, lymph node metastasis increased by 1.9 times with each one point increase in TG2 staining score. CONCLUSION TG2 staining score of the primary tumor may be a predictive factor for lymph node metastasis. High or low TG2 scores may effect the frequency of follow-up and decision of treatment regimens.

Abstract
INTRODUCTION Insulin-like growth factor-II messenger RNA-binding protein-3 (IMP3) over-expression is a predictor of tumor recurrence and metastases in some types of human melanoma. Our objective was to evaluate the immunohistochemical expression of IMP3 and other molecules related to tumor prognosis in melanoma-xeno-tumors undergoing treatment. We test the effect of radiotherapy (RT) and mesenchymal stromal cells (MSCs) treatment, analyzing the tumorigenic and metastatsizing capacity in a mice melanoma xenograft model. MATERIALS AND METHODS We inoculated A375 and G361 human melanoma cell lines into NOD/SCID gamma mice (n = 64). We established a control group, a group treated with MSCs, a group treated with MSCs plus RT, and a group treated with RT. We assessed the immunohistochemical expression of IMP3, E-cadherin, N-cadherin, PARP1, HIF-1α, and the proliferation marker Ki-67. Additionally, we performed a retrospective study including 114 histological samples of patients diagnosed with malignant cutaneous superficial spreading melanoma (n = 104) and nodular melanoma (n = 10) with at least 5 years of follow-up. RESULTS Most morphological and immunohistochemical features show statistically significant differences between the 2 cell lines. The A375 cell line induced the formation of metastases, while the G361 cell line provoked tumor formation but not metastases. All three treatments reduced the cell proliferation evaluated by the Ki-67 nuclear antigen (p = 0.000, one-way ANOVA test) and reduced the number of metastases (p = 0.004, one-way ANOVA test). In addition, the tumor volumes reduced in comparison with the control groups, 31.74% for RT + MSCs in the A357 tumor cell line, and 89.84% RT + MSCs in the G361 tumor cell line. We also found that IMP3 expression is associated with greater tumor aggressiveness and was significantly correlated with cell proliferation (measured by the expression of Ki-67), the number of metastases, and reduced expression of adhesion molecules. CONCLUSIONS The combined treatment of RT and MSCs on xenografted melanomas reduces tumor size, metastases frequency, and the epithelial to mesenchymal transition/PARP1 metastatic phenotype. This treatment also reduces the expression of molecules related to cellular proliferation (Ki-67), molecules that facilitate the metastatic process (E-cadherin), and molecules related with prognosis (IMP3).

Abstract
BACKGROUND Multinucleated giant cells (MGCs) in bladder carcinomas are poorly studied. AIM To describe the function, morphogenesis, and origin of mononuclear and MGCs in urothelial carcinoma (UC) of the bladder in Bulgarian and French patients. METHODS Urothelial bladder carcinomas (n = 104) from 2016-2020 were analyzed retrospectively using immunohistochemical (IHC) and histochemical stain examination. Giant cells in the bladder stroma were found in 35.6% of cases, more often in high-grades. RESULTS We confirm that MGCs in the mucosa in UC of the bladder were positive for both mesenchymal and myofibroblast markers (vimentin, smooth muscle actin, Desmin, and CD34) and the macrophage marker CD68. Furthermore, IHC studies revealed the following profile of these cells: Positive for p16; negative for epithelial (CK AE1/AE3 and GATA-3), vascular (CD31), neural (PS100 and C-KIT), cambial, blastic (CD34-blasts and C-KIT), and immune markers (IG G, immunoglobulin G4, and PD-L1); no proliferative activity, possess no specific immune function, and cannot be used to calculate the Combined Positive Score scale. CONCLUSION In conclusion, the giant stromal cells in non-tumor and tumor bladder can be used as a characteristic and relatively constant, although nonspecific, histological marker for chronic bladder damage, reflecting the chronic irritation or inflammation. Likewise, according to the morphological and IHC of the mono- and multinucleated giant cells in the bladder, they are most likely represent telocytes capable of adapting their morphology to the pathology of the organ.

Abstract
BACKGROUND AND AIM Immunohistochemistry indicators are increasingly being used to predict the survival prognosis of cancer patients after surgery. This study aimed to combine some markers to establish an immunohistochemical score (MSI-P53-Ki-67[MPK]) and stratify postoperative patients with gastric cancer according to the score. METHODS We used 245 patients who underwent surgery at one center as the training cohort and 111 patients from another center as the validation cohort. All patients were treated between January 2012 and June 2018. The training cohort was screened for prognostic factors, and MPK scores were established using univariate and multifactorial COX risk proportional models. Patients were prognostically stratified according to the MPK score after gastrectomy for gastric cancer. Overall survival (OS) and recurrence-free survival (RFS) rates were compared among low-, intermediate-, and high-risk groups using the Kaplan-Meier method, and survival curves were plotted. Finally, the MPK score was validated using the validation cohort. RESULTS In the training group, there were statistically significant differences in OS and RFS in the low, medium, and high-risk groups (P < 0.001). Thirty patients were in the high-risk group (12.2%). The median survival times of the three groups were 64.0, 44.0, and 23.0, respectively, and median times to recurrence were 54.0, 35.0, and 16.0 months, respectively. In the validation group, the prognosis in the three risk groups remained significantly different (P < 0.001). CONCLUSIONS The novel MPK score could effectively predict the postoperative OS and RFS of gastric cancer patients, risk-stratify postoperative patients, and identify postoperative high-risk patients for refined management.

Abstract
Current means to quantify cells, gene expression, and fibrosis of liver histological slides are not standardized in the research community and typically rely upon data acquired from a selection of random regions identified in each slide. As such, analyses are subject to selection bias as well as limited subsets of available data elements throughout the slide. A whole-slide analysis of cells and fibrosis would provide for a more accurate and complete quantitative analysis, along with minimization of intra- and inter-experimental variables. Herein, we present LiverQuant, a method for quantifying whole-slide scans of digitized histologic images to render a more comprehensive analysis of presented data elements. After loading images and preparing the project in the QuPath program, researchers are provided with one to two scripts per analysis that generate an average intensity threshold for their staining, automated tissue annotation, and downstream detection of their anticipated cellular matrices. When compared with two standard methodologies for histological quantification, LiverQuant had two significant advantages: increased speed and a 50-fold greater tissue area coverage. Using publicly available open-source code (GitHub), LiverQuant improves the reliability and reproducibility of experimental results while reducing the time scientists require to perform bulk analysis of liver histology. This analytical process is readily adaptable by most laboratories, requires minimal optimization, and its principles and code can be optimized for use in other organs. Graphical overview.

Abstract
BACKGROUND Despite recent advances in therapy modalities of colorectal cancer (CRC), it is still the third cause of cancer-related deaths worldwide. Thus, the search for new target therapies became mandatory. DDR1 is a collagen receptor that has a suggested role in cellular proliferation, tumor invasion, and metastasis. MATERIAL AND METHODS Forty-eight cases of CRC, 20 of CR adenoma, and 8 cases of non-tumoral colonic tissue were subjected to immunohistochemistry by DDR1 and β-catenin antibodies. Results were compared among the different studied groups and correlated with clinicopathologic data and available survival data. Also, the expression of both proteins was compared versus each other. Results were compared among the 3 studied groups and correlated with clinicopathologic and survival data. RESULTS It revealed a stepwise increase of DDR1 expression among studied groups toward carcinoma (P = 0.006). DDR1 expression showed a direct association with stage D in the modified Dukes' staging system (P = 0.013), higher-grade histologic types (P = 0.008), and lymph node invasion (P = 0.028) but inverse correlation with the presence of intratumoral inflammatory response (TIR) (P = 0.001). The shortest OS was associated with strong intensity of DDR1 (P = 0.012). The DDR1 and β-catenin expressions were significantly correlated (P = 0.028), and the combined expression of both was correlated with TNM staging (P = 0.017). CONCLUSION DDR1 overexpression is a frequent feature in CRC and CR adenoma. DDR1 is a poor prognostic factor and a suppressor of the TIR. DDR1 and β-catenin seem to have a synergistic action.

Abstract
Giardiasis, a parasitic infection of the gastrointestinal tract, is prevalent worldwide. The integrity of the intestinal epithelial barrier plays an important defensive role in giardiasis, and as Oral supplementation with prebiotics and probiotics is known to reinforce the intestinal barrier in many gastrointestinal diseases, this study assessed the effects of prebiotic and probiotic supplementation in giardiasis and compared the results with those obtained after nitazoxanide therapy. Swiss albino male lab-bred mice (n = 50) were divided into three major groups; Group I (control group), i.e., negative (noninfected nontreated) and positive controls (infected nontreated); Group II (preventive group), in which mice were provided prebiotic, probiotic, or a combination for 7 days before of infection, and Group III (therapy group), in which mice were administered prebiotic, probiotic, combined supplements and nitazoxanide from day 12 post-infection. The assessment was achieved through Giardia cyst count, histopathological examination and ultrastructure study. Also, Serological and immunohistochemical parameters were done to evaluate the modulation of IgA levels. Oral supplementation with prebiotic and probiotic, either before or after infection (in preventive or therapy groups respectively) resulted in a significant reduction in Giardia cyst shedding. Remarkable histological and ultrastructure improvement in the intestinal changes, along with a significant increase in the serological and immunohistochemical IgA levels, were seen in mice provided combined supplements and nitazoxanide (in therapy group). Thus, our results indicate that combined prebiotic and probiotic supplementation has promising anti-Giardia activity and that it can restore intestinal structures and modulate IgA response, apart from providing synergistic effects when added to nitazoxanide.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Probiotic fermentation is a mild and safe biological method to boost the performance of herbs. Portulaca oleracea L. (PO), with folklore records of purgative, anti-dermatological and anti-epidemic effects, has been demonstrated to possess anti-inflammatory, immunomodulatory, and antioxidant properties. However, the potential of PO for the treatment of atopic dermatitis (AD) has not been sufficiently explored. AIM OF STUDY This study aimed to evaluate the therapeutic benefits of PO and fermented Portulaca oleracea L. (FPO) and explore their intrinsic mechanisms. METHODS By utilizing 2,4-dinitrofluorobenzene-induced AD mice as a model, the histopathology of the lesions was observed using H&E and toluidine blue staining methods; the levels of immunoglobulin E (Ig E), histamine (HIS), and thymic stromal lymphopoietin (TSLP) in serum were measured using ELISA, whereas, the expression of inflammatory cytokines in skin lesion was measured using ELISA and immunohistochemistry experiments. The expression of tumor necrosis factor-α (TNF-α), IKKα, NF-κB mRNA was measured using qPCR; and the expression of TNF-α、p-IKKα, p-IκBα, p-NF-κB was measured using western blotting. RESULTS Both 20 mg/mL PO and FPO alleviated mast cell infiltration and lesion pathology, reduced serum levels of Ig E, HIS and TSLP, down-regulated the expression of AD-related inflammatory cytokines, such as, TNF-α, interferon-γ, and interleukin-4, and increased filaggrin expression. Furthermore, they inhibited the expression of TNF-α, IKKα, and NF-κB genes and TNF-α, p-IKKα, p-NF-κB and p-IκBα proteins associated with the NF-κB signaling pathway. CONCLUSIONS PO and FPO has a positive therapeutic potential on AD, indicating that it may be employed as alternative therapies for AD.

Abstract
BACKGROUND The proteasome in eukaryotic cells can degrade a variety of proteins and plays an important role in regulating the cell cycle, cell survival and apoptosis. The proteasome receives much attention as a potential chemotherapeutic target for treatment of a variety of infectious parasitic diseases, but few studies of proteasomes have been done on parasitic nematodes. METHODS A proteasomal β5 subunit encoding gene (named Hc-pbs-5) and its inferred product (Hc-PBS-5) in Haemonchus contortus were identified and characterized in this study. Then, the transcriptional profiles and anatomical expression were studied using an integrated molecular approach. Finally, a specific proteasome inhibitor bortezomib (BTZ), together with RNA interference (RNAi), was employed to assess the function of Hc-PBS-5. RESULTS Bioinformatic analysis revealed that the coding sequence of Hc-pbs-5 was 855 bp long and encoded 284 amino acids (aa). The predicted protein (Hc-PBS-5) had core conservative sequences (65-250 aa) belonging to N-terminal nucleophile (Ntn) family of hydrolases. Real-time PCR results revealed that Hc-pbs-5 was continuously transcribed in eight developmental stages with higher levels at the infective third-stage larvae (L3s) and adult males of H. contortus. Immunohistochemical results revealed that Hc-PBS-5 was expressed in intestine, outer cuticle, muscle cells under the outer cuticle, cervical glands and seminal vesicles of male adults and also in intestine, outer cuticle, cervical glands, uterine wall, eggs and ovaries of female adults of H. contortus. BTZ could reduce proportions of egg hatching, and the fourth-stage larvae (L4s) developed from the exsheathed L3s (xL3s) of H. contortus. In addition, silencing Hc-pbs-5 by soaking the specific double-stranded RNA (dsRNA) could decrease the transcription of Hc-pbs-5 and result in fewer xL3s developing to L4s in vitro. CONCLUSIONS These results indicate that proteasomal β5 subunit plays an important role in the growth, development and life span of H. contortus.

Abstract
OBJECTIVES Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome is the most common periodic fever syndrome during early childhood period with regular febrile attacks of sterile upper airway inflammation. The cessation of attacks following tonsillectomy points to fundamental role of tonsil tissue on etiopathogenesis of disease, which is not clarified satisfactorily. The aim of this study is to explore the immunological basis of PFAPA by evaluating the cellular properties of tonsils, and microbial exposition such as Helicobacter pylori on tonsillectomy materials. METHODS The paraffinized tonsil samples of 26 PFAPA and 29 control patients with obstructive upper airway disorder were compared in terms of immunohistochemical staining features including CD4, CD8, CD123, CD1a, CD20, and H. pylori. RESULTS The median number of CD8+ cells was 1485 (1218-1287) in PFAPA while it was 1003 (852-1261.5) in control group and the difference was statistically significant (p=0.001). Similarly, CD4+ cell counts were statistically higher in PFAPA group than control (833.5 vs 622). The ratio of CD4/CD8 did not differ between two groups; also, there was no statistically difference in terms of the other immunohistochemical staining results, such as CD20, CD1a, CD123 and H. pylori. CONCLUSION This is the largest number of pediatric tonsillar tissue study of PFAPA patients in current literature and we emphasized the triggering effects of CD8+ and CD4+ T-cells on PFAPA tonsils. KEY POINTS • The cessation of attacks following tonsillectomy points to fundamental role of tonsil tissue on etiopathogenesis of disease, which is not clarified satisfactorily. • In current study, 92.3% of our patients did not experience any attacks following operation similarly with literature. • We observed the increased number of CD4+ and CD8+ T cell counts on PFAPA tonsils compared to control group and emphasized the active role of both CD4+ and CD8+ cells localized on PFAPA tonsils in immune dysregulation. • Some other cell types evaluated in this study such as CD19+ (B cells), CD1a (dendritic cells), and CD123 (IL-3 receptors, for pluripotent stem cells) and H. pylori did not differ in PFAPA patients compared to the control group.

Abstract
An assessment of environmental quality in Amazonian estuaries utilizing histological and immunohistochemical biomarkers concomitantly with analyses of trace metals in the tissues of Sciades herzbergii, also considering physical chemical analyzes of the water. 352 animals were captured from two sites and during two periods (dry and rainy). Site 1: São Marcos Bay - heavy anthropic influence and Site 2: Caeté estuary-preserved estuary. In the laboratory, the fish were weighed (g) and measured (cm). Fragments of gills and liver were analyzed using histology and immunohistochemistry (Caspase 3). The specimens from Site 1 presented a low-value condition factor, with the highest concentrations of Al, Cd, and Hg appearing in the muscle, and most severe damages to gills and liver. In contrast, individuals from Site 2 presented a high-value condition factor and showed low metal concentrations in the muscle with only slight tissue lesions. Furthermore, our results demonstrated that seasonal changes affect metal modulation and pathologies in fish at Site 1. The sentinel species chosen in this study is considered a strong bioindicator of pollution and the combination of different biomarkers was efficient in providing a clear view of the signs of exposure to pollutants, and the risks posed to fish health by the presence of metals in the environment, especially in Site 1.

Abstract
MOTIVATION With the sites of antigen expression different, the segmentation of immunohistochemical (IHC) histopathology images is challenging, due to the visual variances. With H&E images highlighting the tissue structure and cell distribution more broadly, transferring more salient features from H&E images can achieve considerable performance on expression site agnostic IHC images segmentation. METHODS To the best of our knowledge, this is the first work that focuses on domain adaptive segmentation for different expression sites. We propose an expression site agnostic domain adaptive histopathology image semantic segmentation framework (ESASeg). In ESASeg, multi-level feature alignment encodes expression site invariance by learning generic representations of global and multi-scale local features. Moreover, self-supervision enhances domain adaptation to perceive high-level semantics by predicting pseudo-labels. RESULTS We construct a dataset with three IHCs (Her2 with membrane stained, Ki67 with nucleus stained, GPC3 with cytoplasm stained) with different expression sites from two diseases (breast and liver cancer). Intensive experiments on tumor region segmentation illustrate that ESASeg performs best across all metrics, and the implementation of each module proves to achieve impressive improvements. CONCLUSION The performance of ESASeg on the tumor region segmentation demonstrates the efficiency of the proposed framework, which provides a novel solution on expression site agnostic IHC related tasks. Moreover, the proposed domain adaption and self-supervision module can improve feature domain adaption and extraction without labels. In addition, ESASeg lays the foundation to perform joint analysis and information interaction for IHCs with different expression sites.

Abstract
Assessing histological changes is essential for characterizing muscle disease progression and for studying the response to therapies in Duchenne muscular dystrophy (DMD), an X-linked progressive muscle-wasting disease caused by the loss of the dystrophin protein. Canine models are by far the best-characterized large animal models for DMD. In this chapter, we describe methods for muscle tissue collection and storage, hematoxylin and eosin staining for studying general muscle morphology, and special staining protocols for evaluating fibrosis, calcification, and neuronal nitric oxide synthase (nNOS) activity. We also provide immunofluorescence staining protocols that are often used to characterize the expression and localization of dystrophin and components of the dystrophin-associated glycoprotein complex. Lastly, we presented immunohistochemical staining protocols that we use to assess muscle inflammation and immune responses.

Abstract
BACKGROUND Breast cancer in men is a rare and poorly studied disease, and its treatment is based on women breast cancer studies. However, clinical outcome is not the same in men and women. Basic studies and clinical trials in animal models provide detailed information on cancer, origin, development, cell signaling pathways, sites of metastasis, and target molecules. It is necessary to explore the biology of breast cancer in male animal models that allow observing their similarity. METHODS The triple-negative 4T1 breast cancer model was developed in both male and female mice and studied weekly during 4 weeks. For that, twenty 8-week-old female and male BALB/c mice were used. Sixteen mice (eight males and eight females) were inoculated into the second left thoracic mammary pad with 20,000 4T1 cells, resuspended in 20 µL phosphate-buffered saline (PBS). All samples were processed for immunodetection, characterized histopathologically and immunohistochemically. RESULTS In this work, we describe the development of a triple-negative 4T1 breast cancer model in male BALB/c mice. Breast tumors were characterized histopathologically at different time points and corresponded to a moderately differentiated invasive ductal carcinoma, estrogen receptor ER-/progesterone receptor PR-/human epidermal growth factor receptor 2 HER2-/Ki67+, with histological grade II (moderately differentiated; a solid mass with occasional duct formation and moderate to severe nuclear pleomorphism), infiltrating the adipose and muscular tissue, and metastasis to lungs. From the results, we did not observe differences in the time of tumor development, necrosis, color change of tumor tissue, and lung metastasis between male and female mice. Even though we did not find histological differences, response to treatment and molecular signaling may be different. CONCLUSIONS The histogenesis of male breast tumors was similar to that of female BALB/c mice. The histological and immunohistochemical characteristics of male tumors also match the features reported for stage IV human breast cancer of men and women. The murine male breast cancer model described here can be a significant tool to explore the molecular mechanisms involved in male breast cancer tumorigenesis and metastasis and may bring new approaches for clinical treatment of triple-negative breast cancer in men.

Abstract
OBJECTIVE To investigate the correlation between expression levels of adipokine and clinicopathological features and prognosis of patients with upper tract urothelial carcinoma (UTUC) based on immunohistochemical staining and bioinformatics analysis. METHODS The 8 adipokines in this study included adiponectin (AdipoQ), leptin (LEP), interleukin (IL)-6, IL-10 and their receptors (AdipoR1, AdipoR2, LEPR, IL-6R, IL-10RA, IL-10RB). Tissue samples of patients with UTUC who underwent surgical treatment in Peking University People's Hospital from January 2014 to April 2021 were selected for immunohistochemical staining. Their quantitative gene expression data were calculated by H-Score, and relevant clinical and follow-up data were collected retrospectively. Transcription group sequencing data of UTUC patients in Gene Expression Omnibus database (GSE134292 dataset) were downloaded for comparison. Chi-square test or t-test was used to compare the expression level of adipokine between non-muscle invasive group and muscle invasive group. Univariate and multivariate Cox regression analysis and Kaplan-Meier survival curve were utilized to analyze independent predictors of overall survival (OS), disease-free survival (DFS), intravesical recurrence-free survival (IVRFS) in the both cohorts. The P < 0.05 was considered statistically significant. RESULTS In the study, 63 tissue samples of the patients with UTUC who underwent surgical treatment in Peking University People's Hospital and 57 UTUC patients in GSE134292 dataset were selected. In immunohistochemical cohort, the expressions of AdipoQ (P=0.003 6), AdipoR1 (P=0.006 5), LEP (P=0.007 7), IL-10 (P=0.006 9), and IL-10RA (P=0.008 9) were statistically higher in muscle invasive group. In GSE134292 cohort, the expressions of AdipoR1 (P=0.000 4), AdipoR2 (P=0.000 4), IL-6 (P=0.005 0), IL-10 (P=0.001 7), and IL-10RA (P=0.008 1) were statistically higher in muscle invasive group. Kaplan-Meier survival curve and multivariate Cox regression analysis showed that high IL-10RA expression was an independent predictive factor of IVRFS (P=0.044, HR=0.996, 95%CI: 0.992-0.998) in immunohistochemical cohort, which was confirmed in GSE134292 cohort (P=0.014, HR=0.515, 95%CI: 0.304-0.873). CONCLUSION The expression levels of AdipoQ, AdipoR1, IL-10, and IL-10RA were correlated with tumor stage, suggesting that these adipokines played important roles in tumor progression. IL-10RA was an independent predictor of IVRFS, suggesting that IL-10 and its receptor played a critical role in tumor recurrence.

Abstract
Background The role of the PRDM5 in esophageal squamous cell carcinoma (ESCC) has not been revealed. This study investigated the relationship between PRDM5 expression and survival outcome in esophageal squamous cell carcinoma and explored the mechanism in tumor development. Methods In present study, expression of PRDM5 mRNA in esophageal squamous cell carcinoma patients was conducted using the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database. The expression of PRDM5 was assessed by immunohistochemical staining. Kaplan-Meier curve and Cox regression analysis was performed to analyze the survival outcome and independent predictive factors. qRT-PCR and Methylation-specific PCR were performed to identify the mRNA level of PRDM5 and Methylation rate. Cibersort algorithm to analyze the relationship between PRDM5 expression and immune cell invasion. Western-blot was performed to confirm the expression of esophageal tumor tissues and adjacent tissues. Results The TCGA database and GEO database show that PRDM5 mRNA level in esophageal squamous cell carcinoma adjacent tissues was higher than that of cancer tissues, and ESCC patients with high expression of PRDM5 mRNA had better overall survival. Tissue microarray showed that the protein level of PRDM5 in the adjacent tissues of patients with ESCC was higher than that in cancer tissues, and the expression level of PRDM5 was significantly correlated with the grade of clinicopathological characteristics (P < 0.001). Patients with high expression of PRDM5 displayed a better OS and DFS. Cox regression analysis showed that PRDM5 was an independent risk factor and prognostic factor for ESCC patients (HR: 2.626, 95%CI: 1.824–3.781; P < 0.001). The protein level of PRDM5 matched with the transcriptional level, whereas the DNA methylation affected the transcriptional level. Cibersort showed that T cells CD4 memory resting, mast cells resting, eosinophils, M2 macrophages and mast cells activated were significantly positively correlated with PRDM5 expression (P < 0.05), while regulatory T cells, monocytes and dendritic cells negatively correlated with PRDM5 expression (P < 0.05). Conclusion PRDM5 can be used as a biomarker to predict the survival of ESCC patients. Furthermore, PRDM5 expression in ESCC cells may affect WNT/β-catenin signaling pathways, thus further affect the ESCC cell proliferation, migration, and invasion capacity.

Abstract
BACKGROUND Esophageal granular cell tumor (eGCT) is a relatively rare, usually benign neoplasm of the neuroectoderm. It is derived from Schwann cells. Clinical symptoms of this disease are non-specific. However, the most common presenting symptom is dysphagia, which is mostly misdiagnosed as esophageal polyps under gastroscopy, yet it has a 2% chance of forming cancers. We report the case of a 52-year-old woman with solitary eGCT, then analysed retrospectivelyanalyze the clinical features and elucidate on the reduction of misdiagnosis and missed diagnosis.
CASE SUMMARY A 52-year-old woman was diagnosed with “esophageal granulossoma” after esophagoscopy, which was mistaken for eGCT.
CONCLUSION eGCT diagnosis depends on characteristic pathomorphologies and detection of the S-100 protein. Endoscopic mucosal resection is the preferred therapeutic method.

Abstract
BACKGROUND Microsatellite instability is caused by loss of expression of DNA mismatch repair (MMR) proteins, which are involved in one of significant pathways that lead to colorectal cancer development and progression. Both Cdx-2 and p53 play an inhibitory role in colorectal cancer and are related to some clinicopathological features.
AIM To analyze the significance of expression of MMR proteins (MLH1, MSH2, PMS2, and MSH6), CDX-2, and p53 in colorectal adenocarcinoma.
METHODS A total of 175 patients with colorectal adenocarcinoma who were operated at the Affiliated Hospital of Yangzhou University from January 2017 to March 2021 were selected. The expression levels of MLH1, MSH2, PMS2, MSH6, CDX-2, and p53 in colorectal cancer were detected by immunohistochemical method. The association of the expression of the above proteins with clinicopathological features of colorectal adenocarcinoma was explored by chi-square test, and Spearman rank correlation was used for correlation analysis.
RESULTS Among 175 colorectal adenocarcinoma patients, there were 39 patients with negative expression of all four MMR proteins (22.3%). The negative expression of MSH2, MSH6, MLH1, and PMS2 was found in 12 (6.9%), 1 (0.6%), 17 (9.7%), and 28 (16.0%) cases, respectively. Among 91 colorectal adenocarcinoma patients, 34 (35.1%) had negative expression of CDX-2, and 7 (25%) had negative expression of p53 in colorectal adenocarcinoma. The negative expression of MMR proteins was significantly correlated with the age of onset, tumor site, and degree of differentiation in colorectal adenocarcinoma patients (P < 0.05), but had no significant correlation with patient gender, tumor invasion depth, or lymph node metastasis (P > 0.05). There was no correlation between the expression of MMRs protein and that of CDX-2 and p53 (P > 0.05).
CONCLUSION The expression of MMR proteins is related to the age of onset, tumor site, and degree of differentiation. The detection of MMR proteins has important clinical significance for the early diagnosis of colorectal adenocarcinoma, the formulation of therapeutic plan, and the assessment of prognosis.

Abstract
Trichinellosis is a re-emerging zoonotic disease that has become a public health concern since its reported human outbreaks in many countries. The traditional therapy has many adverse effects in addition to the developing resistance. So, this necessitates finding effective natural alternatives. The current study targeted to assess the potential therapeutic effects of Zingiber officinale and Cinnamomum zeylanicum in comparison to albendazole, a conventional therapy for treatment of trichinosis. Sixty mice were classified into five groups (12 mice each), non-infected control, infected control, combined albendazole and prednisolone, Zingiber officinale, and Cinnamomum zeylanicum treated groups. Mice sacrifice was performed on the 7th and 35th days post infection for intestinal and muscular phases respectively. Efficiency of the used preparations was assessed by parasitological, histopathological, immunohistochemical, biochemical studies in addition to ultrastructural evaluation using transmission electron microscopy. A significant reduction in the mean number of T. spiralis adult worms and larvae was observed in Zingiber officinale and Cinnamomum zeylanicum treated groups, (64.5%, 50.8%) and (68%, 54.6%) respectively. Also, both extracts showed moderate cytoplasmic reactivity for TGF-β1, (69.3% & 67.8%) respectively. The highest reduction in serum TNF- α level was observed in Zingiber officinale treated group during the muscle phase (58.4%) while in the intestinal phase was 50%. The ultrastructural study revealed degenerative effects on both adults and larvae in addition to obvious improvement of the histopathological changes in the small intestine and muscles. We concluded that these herbal extracts especially Zingiber officinale can be considered a practical and successful alternative for the treatment of trichinellosis.

Abstract
INTRODUCTION Recent studies suggested that microsatellite instability/mismatch repair deficiency (MSI/MMR-d) might define a clinicopathologically distinct subset of uterine carcinosarcomas (UCSs). OBJECTIVE The aim of this study was to compare clinicopathological features between MSI/MMR-d and microsatellite-stable/mismatch repair-proficient (MSS/MMR-p) UCSs. METHODS A quantitative systematic review was performed by searching electronic databases from January 2000 to January 2021. All studies assessing MSI/MMR status in UCS were included. Odds ratio (OR) with a significant two-tailed p value <0.05 was used to assess the association of MSI/MMR-d with clinicopathological features. RESULTS Eleven studies with 783 patients were included. MSI/MMR-d was directly associated with endometrioid (pure: p < 0.001; pure + mixed: p < 0.001), undifferentiated/dedifferentiated (p < 0.001), and clear cell carcinoma component (p = 0.046), and inversely associated with age >60 (p = 0.034), serous carcinoma component (pure: p < 0.001; pure + mixed: p < 0.001), heterologous sarcoma component (p = 0.027), TP53-mutation/p53-abnormal expression (p < 0.001), and recurrence (p < 0.001). MSI/MMR-d showed no significant association with advanced FIGO stage (OR = 1.259; p = 0.517), low-grade carcinoma component (pure: p = 0.596; pure + mixed: p = 0.307), mixed carcinoma component (p = 1), and proportion of patients "dead of disease" (p = 0.352), "alive with disease" (p = 1) or with "no evidence of disease" (p = 0.458). CONCLUSION MSI/MMR-d UCSs show younger age, more common endometrioid, undifferentiated or clear cell carcinoma component, and less common serous carcinoma component, heterologous sarcoma component, and TP53 mutation than MSS/MMR-p UCSs. Given the discrepancy between recurrence rate and oncologic outcomes at the last follow-up, further studies are necessary to define whether MSI/MMR-d UCSs have better prognosis.

Abstract
The study aimed to explore the neutrophil's spatial distributions used to estimate the histological age of contused skeletal muscle, and assessed the accuracy of various indicators, such as the proportion of neutrophils, "neutrophil mean distance," and distribution of neutrophils in areas of "contiguous contour lines." Fifty-five Sprague-Dawley rats were divided randomly into a control group and contusion groups at 1, 1.5, 2, 3, 4, and 6 h, as well as 1, 3, 5, and 15 days, post-injury (n = 5 per group). Nuclei and neutrophils were detected by hematoxylin and eosin (HE) staining and immunohistochemical (IHC) staining. At 0-24 h after injury, the distribution of neutrophils at distances of 100, 200, 300, 400, 500, and 600 µm from adjacent blood vessels was determined, and the best samples were screened to estimate wound age. To estimate wound age as accurately as possible, Fisher discriminant analysis (FDA) of the proportion of neutrophils, neutrophil mean distance, and distribution of neutrophils was performed, and 100.0% and 95.0% of the original and cross-validated cases were correctly classified, respectively. The spatial distribution of neutrophils at different distances from adjacent blood vessels showed a strong correlation with the histological age of contusion skeletal muscle, and the combination of the proportion of neutrophils, neutrophil mean distance, and distribution of neutrophils could be used to accurately estimate wound age.

Abstract
Background Metastatic breast carcinoma is commonly considered during differential diagnosis when metastatic disease is detected in females. In addition to the tumor morphology and documented clinical history, sensitive and specific immunohistochemical (IHC) markers such as GCDFP-15, mammaglobin, and GATA3 are helpful for determining breast origin. However, these markers are reported to show lower sensitivity in certain subtypes, such as triple-negative breast cancer (TNBC). Materials and methods Using bioinformatics analyses, we identified a potential diagnostic panel to determine breast origin: matrix Gla protein (MGP), transcriptional repressor GATA binding 1 (TRPS1), and GATA-binding protein 3 (GATA3). We compared MGP, TRPS1, and GATA3 expression in different subtypes of breast carcinoma of (n = 1201) using IHC. As a newly identified marker, MGP expression was also evaluated in solid tumors (n = 2384) and normal tissues (n = 1351) from different organs. Results MGP and TRPS1 had comparable positive expression in HER2-positive (91.2% vs. 92.0%, p = 0.79) and TNBC subtypes (87.3% vs. 91.2%, p = 0.18). GATA3 expression was lower than MGP (p < 0.001) or TRPS1 (p < 0.001), especially in HER2-positive (77.0%, p < 0.001) and TNBC (43.3%, p < 0.001) subtypes. TRPS1 had the highest positivity rate (97.9%) in metaplastic TNBCs, followed by MGP (88.6%), while only 47.1% of metaplastic TNBCs were positive for GATA3. When using MGP, GATA3, and TRPS1 as a novel IHC panel, 93.0% of breast carcinomas were positive for at least two markers, and only 9 cases were negative for all three markers. MGP was detected in 36 cases (3.0%) that were negative for both GATA3 and TRPS1. MGP showed mild-to-moderate positive expression in normal hepatocytes, renal tubules, as well as 31.1% (99/318) of hepatocellular carcinomas. Rare cases (0.6–5%) had focal MGP expression in renal, ovarian, lung, urothelial, and cholangiocarcinomas. Conclusions Our findings suggest that MGP is a newly identified sensitive IHC marker to support breast origin. MGP, TRPS1, and GATA3 could be applied as a reliable diagnostic panel to determine breast origin in clinical practice.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary malignancy of the adult liver and morbidity are increasing in recent years, however, there is still no effective strategy to prevent and diagnose HCC. Therefore, it is urgent to research the effective biomarker to predict clinical outcomes of HCC tumorigenesis. In the current study, differentially expressed genes in HCC and normal tissues were investigated using the Gene Expression Omnibus (GEO) dataset GSE144269 and The Cancer Genome Atlas (TCGA). Gene differential expression analysis and weighted correlation network analysis (WGCNA) methods were used to identify nine and 16 key gene modules from the GEO dataset and TCGA dataset, respectively, in which the green module in the GEO dataset and magenta module in TCGA were significantly correlated with HCC occurrence. Third, the enrichment score of gene function annotation results showed that these two key modules focus on the positive regulation of inflammatory response and cell differentiation, etc. Besides, PPI network analysis, mutation analysis, and survival analysis found that SLITRK6 had high connectivity, and its mutation significantly impacted overall survival. In addition, SLITRK6 was found to be low expressed in tumor cells. To summarize, SLITRK6 mutation was found to significantly affect the occurrence and prognosis of HCC. SLITRK6 was confirmed as a new potential gene target for HCC, which may provide a new theoretical basis for personalized diagnosis and chemotherapy of HCC in the future.

Abstract
Newcastle disease (ND) is a highly contagious infection of many avian species, mainly chickens and turkeys, with a devastating impact on worldwide poultry production. This study was designed to examine the effect of virulent ND infection in turkey's tissues and the tissue tropism of the virus. During the previous study period, poults were inoculated at 32 days of age with 105 EID50 virulent Newcastle disease virus. Three poults on days 0, 1, 2, 3, 4, 6, 7, and 14 postinoculations (PI) were selected from each group. They were euthanized by intravenous sodium pentobarbital injection. After macroscopic observation, to histopathological and immunohistochemical studies, the spleen, bursa, cecal tonsils, intestine, proventriculus, lung, kidney, and brain were sampled. Clinically, the infected turkeys exhibited loss of appetite, severe depression, down on hock joint, white to greenish (sometimes bloody) diarrhea, nervous signs, and mild respiratory problems. Out of 45 birds inoculated, 9 (20%) died. Histopathological effects in lymphoid tissues included necrosis and penetration of mononuclear cells on day 4 PI, and subsequent follicular lymphoid depletion on days 6 and 8 PI was observed. Based on the immunohistochemical test, on day 3 in cecal tonsils and spleen, and on day 8 PI, all of them were positive for virus antigen. In conclusion, the NDV circulating in Iranian chicken flocks has the potential to cause severe illness in commercial turkeys.

Abstract
BACKGROUND The treatment mode of lung cancer is epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) as a first-line treatment for patients with EGFR mutant in non-small cell lung cancer (NSCLC). At the same time programmed death receptor 1 (PD-1) and its programmed death receptor ligand 1 (PD-L1) inhibitors therapy as the representative immune checkpoint inhibitors (ICIs) has a significant effect in the treatment of lung cancer. The aim of this study was to investigate the correlation between the expression of PD-1 and PD-L1 in NSCLC and clinicopathologic feature, EGFR gene mutation. METHODS The protein expression of PD-1 and PD-L1 was detected by immunohistochemistry from 127 patients with NSCLC and EGFR gene mutation was detected by quantitative polymerase chain reaction (qPCR) to analyze its relation with clinicopathologic feature. Also, the correlation between protein expression of PD-1 and PD-L1 and EGFR mutation. RESULTS The PD-1 positive expression in NSCLC tumor cells and tumor infiltrating immune cells is 53.5% (68/127), PD-L1 is 57.5% (73/127). The PD-1 and PD-L1 expression significantly higher in well-differentiated and moderately-differentiated carcinoma than poorly differentiated carcinoma, I+II than III+IV in clinical staging (P<0.05). The EGFR mutation rate was 46.5% (59/127), correlate with female, without smoking history, adenocarcinoma and well-differentiated and moderately-differentiated patients respectively higher than male, smoking history, squamous carcinoma and poorly differentiated patients (P<0.05). The protein expression of PD-L1 and PD-1 had the consistency in NSCLC patients (kappa=0.107,5, P=0.487). There was a negative correlation between the EGFR mutation and PD-1 and PD-L1 expression (Φ=-0.209, Φ=-0.221, P<0.05). Follow-up of NSCLC patients, the median total survival in under the age of 65, adenocarcinoma, well-differentiated and moderately-differentiated, with PD-L1 expression patients respectively higher than over the age of 65, squamous carcinoma, poorly differentiated, without PD-L1 expression patients (P<0.05). The median survival of hypo expression patients of PD-L1 significantly higher than hyper expression patient (P=0.04). CONCLUSIONS According to the Chinese Expert Consensus on Standards of PD-L1 immunohistochemistry testing for NSCLC, we tested the PD-L1 expression in NSCLC and then the dominant population of anti-PD-1/PD-L1 treatment was screened out. Patients with EGFR mutation were also detected and EGFR mutation was negatively correlated with the expression of PD-1 and PD-L1 as well. On the basis of PD-L1 expression and EGFR mutation status, it may benefit NSCLC patients from individualized treatment. Meanwhile, patients who were under the age of 65, adenocarcinoma, well-differentiated and moderately-differentiated, hypo expression of PD-L1 have a relatively good prognosis, to provide reference for the prognosis evaluation of NSCLC.

Abstract
Fibrous Solitary Tumors are infrequent neoplasms originating from mesenchymal tissues, most commonly arising from the visceral pleura and frequently exhibiting a benign behavior. Extra-pleural localization is unusual and the site of origin of these tumors from the parenchyma of the parotid gland is considered extremely rare. We report the case of a 66-years old woman with non-painful slow-growing left latero-cervical mass, who underwent a gadolinium-enhanced Magnetic Resonance Imaging showing a mass originating from the deep lobe of the parotid gland extending into the retro-pharyngeal space. After a total parotidectomy with tumor excision, a diagnosis of histologically proven fibrous solitary tumor of the parotid gland was made. Two years later, CT scan showed post-operative recurrence and further satellite localization in the neck, distant from the initial mass. We performed a literature review of the published similar cases, in order to clinicopathological and imaging features of this rare entity.

Abstract
Background and aim Deleterious cutaneous tissue damages could result from exposure to thermal trauma, which could be ameliorated structurally and functionally through therapy via the most multipotent progenitor bone marrow mesenchymal stem cells (BM-MSCs). This study aimed to induce burns and examine the effect of BM-MSCs during a short and long period of therapy. Material and methods Ninety albino rats were divided into three groups: group I (control); group II (burn model), the animals were exposed to the preheated aluminum bar at 100°C for 15 s; and group III (the burned animals subcutaneously injected with BM-MSCs (2×106 cells/ ml)); they were clinically observed and sacrificed at different short and long time intervals, and skin samples were collected for histopathological and immunohistochemical examination and analysis of different wound healing mediators via quantitative polymerase chain reaction (qPCR). Results Subcutaneous injection of BM-MSCs resulted in the decrease of the wound contraction rate; the wound having a pinpoint appearance and regular arrangement of the epidermal layer with thin stratum corneum; decrease in the area percentages of ADAMs10 expression; significant downregulation of transforming growth factor-β (TGF-β), interleukin-6 (IL-6), tumor necrotic factor-α (TNF-α), metalloproteinase-9 (MMP-9), and microRNA-21; and marked upregulation of heat shock protein-90α (HSP-90α) especially in late stages. Conclusion BM-MSCs exhibited a powerful healing property through regulating the mediators of wound healing and restoring the normal skin structures, reducing the scar formation and the wound size.

Abstract
Solitary fibrous tumor is a very rare mesenchymal tumor that occurs mostly in the pleura, and there are few reported cases of a presence in the central nervous system, particularly in the cerebellum. In 2016, the WHO classified solitary fibrous tumors into grade I. In this article, we present a case of malignant solitary fibrous tumor recurring 8 years after surgery in a 63-year-old male. Magnetic resonance imaging showed low to intermediate mixed signal intensity on T1W1. Immunohistochemical staining positivity for Vimentin, CD99, CD34 and Bcl-2, it is consistent with the immunohistochemical characteristics of solitary fibrous tumor. We resected the patient's tumor, and the patient was followed up for 3 months with no signs of recurrence. Solitary fibrous tumors are very rare in the central nervous system. Immunohistochemical staining positivity for CD34 and Bcl-2 is strongly expressed in most solitary fibrous tumor. Surgical resection is the preferred treatment. Due to the small number of cases, the biological behavior and prognosis of this tumor need to be further explored.

Abstract
AIM Hyperuricemia is defined by the European Rheumatology Society as a uric acid level greater than 6 mg/dl (60 mg/l or 360 μmol/l). Our goal was to evaluate the hypouricemic effect of nettle. For this reason, we have first of all try to create an hyperuricemic animal model which is very suitable because at the level of literature there is not an exact model, there are many models and our objective is to set an adequate model. MATERIALS AND METHODS An attempt has been made to test acute and chronic hyperuricemia by varying the duration and method of induction of potassium oxonate. Similarly, attempts have been made to induce chronic hyperuricemia through an animal and vegetable diet. The reversibility of hyperuricemia was tested with a maintenance protocol. KEY FINDINGS For the creation of the hyperuricemia model, it has been shown that acute hyperuricemia cannot be induced by short administration of potassium oxonate and persistent chronic hyperuricemia can be induced only after daily administration of oxonate of potassium by intraperitoneal injection for 15 days. Indeed, hyperuricemia was reversible after stopping the administration of potassium oxonate. The high-purine diet is also capable of inducing chronic hyperuricemia but to a less extent. SIGNIFICANCE After creating an adequate model of hyperuricemia while setting the dose of potassium oxonate, route of administration and duration. A maintenance protocol was followed which subsequently made it possible to deduce that the daily administration of potassium oxonate must be continued to maintain the hyperuricemia.

Abstract
Paragangliomas are uncommon neuroendocrine neoplasms that occur in characteristic locations. While parasympathetic paragangliomas are mainly located at the head and neck, sympathetic paragangliomas are mostly located below the neck. Among parasympathetic paragangliomas, pheochromocytomas are the most common. Ninety percent of cases of pheochromocytomas arise within the adrenal gland. We report a case of a 63-year-old woman with an extra-adrenal pheochromocytoma of the organ of Zuckerkandl detected by CT and MRI and subsequently confirmed by postoperative histology and immunohistochemistry.

Abstract
BACKGROUND Gastric cancer is the third leading cause of cancer-related death. Determining molecular and histopathologic tumor features, which may contribute to the development or progression of gastric cancer, can improve the prognosis. Expression patterns of DNA repair proteins such as MLH1, MSH2, MSH6, and PMS2 that are associated with microsatellite instability (MSI) are some of the markers that are useful in predicting the prognosis of gastric cancer. PURPOSE The purpose was to determine the immunohistochemical expression pattern of MLH1, MSH2, MSH6, and PMS2 in tumor specimens of Iranian gastric carcinoma patients. METHODS In this prospective cohort, 186 consecutive patients with gastric cancer, attending Taleghani Hospital, were enrolled. The immunohistochemical expression patterns of MLH1, MSH2, MSH6, and PMS2 in tumor specimens among them were determined. RESULTS The results of this study demonstrated that 91.4% of our gastric cancer patients were negative for MSI, and 8.6% of them were MSI positive. The positive MSI was seen in 5.9% and 15.7% of male and female subjects, respectively, with a significant difference (P = 0.043). The other variables were not related to MSI results (P > 0.05). CONCLUSION According to the obtained results, the expression of MLH1, MSH2, MSH6, and PMS2 in tumor specimens is positive in 8.6% of the total Iranian gastric cancer sample size, which is mainly positive in female subjects. However, it is not related to the location and stage of the tumor.

Abstract
Cisplatin (CP) is a highly effective chemotherapeutic agent against neoplasms, but its clinical utility is limited due to the side effects of its dose-dependent nephrotoxicity. Vitamin E (Vit E) and cod liver oil (CLO) are natural substances with chemoprotective effects. The present study was conducted to evaluate the protective effects of Vit E and/or CLO for CP-induced acute kidney injury (AKI) in rats. This study involved 40 mature male Wistar albino rats that were equally allocated into eight groups: Veh, Vit E, CLO, Vit E + CLO, CP, Vit E + CP, CLO + CP, and Vit E + CLO + CP. The co-administration of Vit E and CLO significantly ameliorated CP-induced elevations in serum creatinine (Cr), blood urea nitrogen (BUN), interleukin 1 beta (IL-1β), and interleukin- 6 (IL-6). Further, rats that received Vit E and/or CLO showed significant decrease in malondialdehyde (MDA) and increases in superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) levels in renal tissues, compared to CP-intoxicated rats. Additionally, the treatment restored the normal histological architecture (except for few cast formations) and upregulated the immunostaining area% of aquaporin 3 (AQP3) and downregulated the immunostaining area% of Bcl2 associated X protein (BAX) and inducible nitric oxide synthase (iNOS). The observed effects were stronger in the combination treatment group. The obtained data revealed that Vit E and CLO co-administration protects against the CP-induced AKI more than monotherapy with Vit E or CLO.

Abstract
BACKGROUND Nevi of special sites (NOSS) are benign melanocytic lesions that occur at particular sites. Although the histological features of NOSS have been described, their immunophenotypic features have not been fully characterized. AIMS To present the clinicopathological characteristics of a case series of NOSS and to characterize their immunohistochemical profile. MATERIALS AND METHODS Thirty-five NOSS were assessed using immunoperoxidase staining techniques for the melanocytic (S100, Melan-A, and HMB45) and proliferation (Ki-67) markers RESULTS: All of the cases of NOSS showed concerning architectural changes (prominent lentiginous melanocytic proliferation, irregularities, crowdedness, and dyhesiveness of the nests), and cytological atypia (large nevomelanocytes with vesicular nuclei, clear cytoplasm, and dusty melanin pigment) that can lead to a misdiagnosis of atypical nevi or even melanomas. All of the cases of NOSS showed diffuse expression of S100 and Melan-A proteins. Ki-67 labeling index of the nevomelanocytes was extremely low. HMB45 protein expression was limited to the junctional and superficial dermal nevomelanocytes. CONCLUSIONS NOSS can show histological features that can easily mimic atypical nevi or melanomas and this diagnostic consideration should be kept in mind to avoid their misdiagnosis. The expression of HMB45 protein in NOSS indicates that their nevomelanocytic cells have an activated phenotype. The decreased HMB45 protein expression following a gradient from junctional to deeper dermal localization in NOSS is indicative of their immunohistochemical maturation.

Abstract
BACKGROUND Previous studies have shown that ASPM is a tumorigenesis associated protein, mutations in ASPM can lead to MCPH. This study mainly explores the relationship between the ASPM expression of lung adenocarcinoma and the development and prognosis of lung cancer. The aim of this study was to investigate the relationship between the expression of abnormal spindle-like microcephaly-associated protein (ASPM) in lung adenocarcinoma and the development and prognosis in lung cancer. METHODS A total of 90 cases of lung adenocarcinoma tissue specimens and 90 cases of benign pulmonary lesions were collected, the expression of ASPM was detected by immunohistochemical technique, and the expression of ASPM in 12 pairs of tissues was detected by real-time quantity polymerase chain reaction and western blot. RESULTS (1) The expression of ASPM in the tissue specimens of benign pulmonary lesions was negative while the expression level of ASPM in lung adenocarcinoma was significantly higher than lung tissue of benign pulmonary lesions (P<0.05). (2) The expression level of ASPM has no remarkable difference in lung adenocarcinoma with lymph node development and the lung cancer without lymph node development, there was no statistically significant (P<0.05). (3) The ASPM expression level in the tumor's size ≥4 cm was significantly higher than than of the size<4 cm (P<0.05). (4) Hierarchical analysis results show that T stage is related to ASPM expression level (P<0.05). (5) The high expression level of ASPM in lung adenocarcinoma was significantly positively correlated with the poor prognosis (P<0.05). CONCLUSIONS (1) The expression level of ASPM in lung cancer is obviously increased and closely related to the progress of lung adenocarcinoma. (2) The expression level of ASPM in lung adenocarcinoma was significantly positively correlated with poor prognosis (P<0.05). (3) Detection of the expression level of ASPM in lung adenocarcinoma help to predict the prognosis of lung adenocarcinoma in advance.

Abstract
BACKGROUND Gastrointestinal stromal tumor (GIST) is the most appearing mesenchymal tumor of the gastrointestinal system. In this study, we are aiming to share the most up to date knowledge about diagnosis and treatment of these tumors by transferring our clinical experience about GISTs. METHODS The 151 patients who were operated between 2006-2020 and whose pathological examination was reported as GIST were analyzed retrospectively. Demographic, clinical, and pathological features and treatment methods of patients were evaluated. RESULTS Seeventy-six of the patients were women and 75 of them were men whose age averages were 66.1 (31-86). The most common location was the stomach (55.6%), followed by the small intestine, retroperitoneal, large intestine, rectum, esophagus, and another organ. With surgical intervention, 139 of them had been cured. Twelve of cases were accepted as inoperable. The diameter of tumors in our cases were between 0.4 cm and 35 cm. Determined mitotic activity was ≤ 5 in 71 patients and 5 < in 80 patients. In 8 of 12 unresectable cases, it has been seen that partial remission after the treatment of 12-month tyrosine kinase inhibitors, C-KIT, was positive in 96.7% of our cases. CD34 and Ki-67 was analyzed in patients. CD34 was found positive in 98 (64.9%) of them, Ki-67 was positive in 82 (54.3%) patients. Patients had been observed for 40 months. CONCLUSION Despite GISTs are not appearing frequently, nowadays they have started to be seen more frequently than before with the growing present-day diagnostic methods. The ideal treatment is performing radical resection without leaving any tumor cells behind. Tyrosine kinase inhibitors have an important place in unresectable cases.

Abstract
Background: In several mammals, subfertility or infertility associated with endometritis was reported. Although there have been studies about endometritis in bitches, the pathophysiological mechanisms are not completely known. Aim: This study aimed to evaluate the immunohistochemical expression of Cyclooxygenase 2 (COX2) in clinically healthy bitches with normal uterine tissue and bitches with endometritis. Methods: Forty-eight mixed breed bitches in diestrus were used. Uterine biopsies were collected for diagnosis [normal endometrium (n = 15; NE), cystic endometrial hyperplasia (n = 1), atrophy (n= 2), acute endometritis (n = 9; AE), subacute endometritis (n = 7; SE), and chronic endometritis (n = 14; CE)]. Immunostaining and quantification of positively stained cells was performed on full-thickness uterine biopsies. Data were analyzed by the GLIMMIX procedure of SAS. Results: COX2 immunostaining was scattered and restricted to cells in the stroma in bitches with NE. However, in bitches with endometritis, strong staining was observed in the luminal epithelium, glandular epithelium, and stromal cells. Staining was also observed in inflammatory cells localized in the stroma as well as inside of the glands. The percentage of COX2 positive stromal cells in bitches with AE, SE, and CE was significantly higher compared with NE (p < 0.005). In addition, the percentage of COX2 positive stromal cells in bitches with SE, and CE was significantly lower compared with AE (p < 0.003). Conclusion: COX2 could be involved in the pathophysiological mechanisms producing endometritis without the presence of cystic endometrial hyperplasia in bitches. However, further researches on this topic are required.

Abstract
Immunohistochemistry is the identification of a cell protein by a specific antibody targeting that protein. It is the most common ancillary test to study the pathology of cancer. Immunohistochemical protein markers are used to differentiate poorly differentiated squamous cell carcinoma from poorly differentiated adenocarcinoma or neuroendocrine carcinomas. They could be used to identify and type the carcinoma in metastatic locations. Importantly, immunodetection of markers also helps in prediction of response to therapies as well as assessing the different biomarkers related to the pathogenesis and clinical behavior of esophageal squamous cell carcinoma. Successful application of the immunochemistry depends on understanding the mechanisms and principles as well as the limitations of the procedure. Automation of the procedure by different models of automatic stainers is widely used in diagnostic laboratories. The use of autostainers streamlines the workflows and certainly reduces the labor, time, and cost of using immunohistochemistry in clinical and research settings.

Abstract
Background Pancreatic cavernous hemangioma is an extremely rare benign tumor that is difficult to diagnose on an imaging examination, and its histopathological examination has rarely been reported. Case presentation Herein, we present the case of a 63-year-old man who was admitted to the hospital due to left upper abdominal pain and defecation unformed for more than 2 years. None of the positive results obtained from the physical examination could explain his symptoms. The imaging examination indicated a multilocular cyst with septa in the head of the pancreas. The patient underwent a pancreaticoduodenectomy, and the pathologic diagnosis was pancreatic cavernous hemangioma. The histopathological examination showed that the lesion was positive for benign vascular markers, such as CD31, CD34 and F8, and negative for lymphocyte markers, such as D2–40. Moreover, it was also positive for ERG and cytokeratin markers, CAM5.2 and AE1/AE3, indicating the complexity of its components, and Ki-67 negativity revealed its benign nature. Conclusions Pancreatic cavernous hemangioma has a complex composition that may be reflected not only in the imaging examination but also in the immunohistochemical detection, and it may achieve a good outcome by surgical excision.

Abstract
AIM This study aims to determine the prognostic significance of phosphatase and tensin homolog (PTEN) loss in breast cancer. METHODS We conducted a meta-analysis study. Sample of this study were research articles that evaluated PTEN loss and prognosis in breast cancer patients. We searched for relevant studies published in PubMed and Proquest from January 2010 to July 2018. We reviewed studies that examined the association between immunohistochemical expression of PTEN and breast cancer prognosis using meta-analysis methods. Pooled risk ratios (RR) were calculated using fixed and random-effect models. Data were processed using Review Manager 5.3 (RevMan 5.3). RESULTS There were 7 studies conducted a systematic review then continued to evaluate the association of PTEN loss and breast cancer prognosis by meta-analysis. There was a significant association of PTEN loss with poor prognosis of breast cancer (RR = 0.76 [95% CI 0.59-0.98 p <0.07), and there was not any significant publication bias for studies included. CONCLUSION This study confirmed PTEN loss is an important independent factor for breast cancer prognosis.

Abstract
Background & Objective: Basal cell carcinoma (BCC) is classified into BCC1 or low risk (nodular, superficial type) and BCC2 or high risk (micronodular, morpheaform, infiltrative, and basosquamous types) based on clinical behavior. This study attempts to evaluate immunohistochemical (IHC) findings and clinical features associated with local aggressiveness and recurrence in BCC lesions. Methods: This is a cross-sectional descriptive study conducted on 42 paraffin blocks (22 BCC1, 20 in BCC2) at Pathology Department of Afzalipour Teaching Hospital. First, demographic features of the patients were recorded and pathology blocks were classified by two dermatopathologists based on histopathological types of BCC1 and BCC2. Then, primary monoclonal antibodies including CD10, CD1a, SMA, Ki67, CD34, and P53 were utilized for IHC study. We compared BCC1 and BCC2 according to IHC markers, demographic features of patients, and tumoral features. Results: The mean number of Langerhans cells (LCs) within epidermis above tumor mass was 14+1.92 and 4.7±1.23 in BCC1 and BCC2, respectively; these results show a significant difference between the two groups (P=0.001). P53 was positive in 41.13±6.39% and 74.5 ±6.26% of the tumor cells in BCC1 and BCC2 groups, which was statistically significant (P=0.001). Also, the mean number of blood vessels was 14.40±1.30 and 21.40±1.97 in BCC1 and BCC2, that was statistically significant (P=0.005). Conclusion: Higher numbers of angiogenesis (SMA positive) and positive P53 were observed in BCC2 than BCC1. Also, more active positive CD1a cells were observed in BCC1 compared to BCC2.

Abstract
Update of clear cell (tubulo) papillary renal cell carcinoma. METHODS: We provide the only three cases described to date in our hospital. RESULTS: One of the new entities of epithelial renal tumors incorporated by the International Society of Urological Pathology (ISUP) in 2013 was the clear cell (tubulo) papillary renal cell carcinoma (RCCtpcc). Although initially was described under other nomenclatures, it was not until 2013 that it was clearly defined. CONCLUSION: The RCCtpcc is usually a low grade and stage subtype of epithelial RCC. It predominates in the sixth decade of life, although cases have already been described in children and young adults. It has a typical immunohistochemical pattern with positive CK7, vimentine, VT and smooth muscle antigen, and negative CD10. They usually have a low malignant potential.

Abstract
PURPOSE Rates of progression of endometrial hyperplasia (EH) to endometrial cancer (EC) are highly variable. Among several prognostic markers, PTEN has been recommended by ESMO-ESGO-ESTRO to identify premalignant EH. However, its prognostic accuracy is unclear. Thus, we aimed to assess: (1) the association between PTEN loss in EH and risk of cancer, and (2) the prognostic accuracy of PTEN immunohistochemistry in EH. METHODS Electronic databases were searched from their inception to June 2018. All studies assessing PTEN immunohistochemistry in EH and the presence of EC on subsequent hysterectomy were included. Odds ratio (OR), sensitivity, specificity, positive and negative predictive value (PPV and NPV), positive and negative likelihood ratio (LR + and LR-) and area under the curve (AUC) on SROC curves were calculated with subgroup analysis (short/long-term; atypical/non-atypical EH). RESULTS Nine retrospective studies assessing 933 EH were included. PTEN loss in EH was significantly associated with increased risk of EC (OR = 3.32, p = 0.001). The association was significant only on the short term ( < 1 year) (OR = 3.45, p = 0.002) and in atypical EH (OR = 1.89, p = 0.01). For overall analysis and short-term/atypical EH subgroup the prognostic accuracy was low, with sensitivity = 0.58 and 0.68, specificity = 0.60 and 0.48, VPp = 0.41 and 0.54, VPN = 0.75 and 0.63, LR + = 1.80 and 1.37, LR - = 0.62 and 0.56, AUC = 0.687 and 0.721, respectively. CONCLUSION PTEN loss in EH is a risk factor for EC, but is not reliable in predicting the risk of EC. In atypical EH, PTEN loss is associated with a risk of concurrent EC of over 50%. This information might integrate the patients' informed consent for the choice of treatment (conservative/hysterectomy), especially in borderline cases. In conservative approach, PTEN loss might suggest closer follow-up.

Immunohistochemical localization of estrogen receptor alpha (ERα) in the oviduct of Indian buffalo during follicular and luteal phases of estrous cycle. Trop Anim Health Prod 2019; 51:1601-1609.

Abstract
The localization and distribution of estrogen receptor alpha (ERα) in different segments of oviduct of buffalo during follicular and luteal phases of estrous cycle were investigated using immunohistochemistry. Tissue samples from the different segments of oviduct from 12 buffaloes (six each during follicular and luteal phases of estrous cycle) were collected from slaughter house after assessing the gross morphology of ovaries. In addition, blood samples were collected from the animals before slaughter to estimate levels of estrogen and progesterone hormones. The tissue distribution of estrogen receptor was determined by immunohistochemical technique using one-step polymer HRPO staining system. The estrogen receptor was localized in the lamina epithelialis, propria submucosa, tunica muscularis, and tunica serosa. The maximum localization was observed in the lamina epithelialis, where both ciliated and secretory cell types were positive for ERα. Percentage of positive cells varied during the follicular and luteal phases of estrous cycle. The lining epithelium of oviductal glands was also intensely positive for ERα. No immunostaining was observed in any tunic of the oviduct when the primary antibody was replaced by antibody diluent or buffer, and it served as negative control. The data showed that highest immune positive cells were observed in the ampulla region of the oviduct and these cells were lowest in the utero-tubal junction (p < 0.05). Infundibulum, ampulla, and isthmus showed a higher percentage of ERα-positive cells during follicular phase of estrous cycle as compared with those of the luteal phase of estrous cycle (p < 0.05). There was no significant difference in the percentage positive cells during the two phases of estrous cycle in the utero-tubal junction. Immunogold labeling with anti-ERα antibody confirmed the findings of immunohistochemical study at subcellular level. The higher expression during the follicular phase was directly correlated with the level of estrogen hormone.
