Abstract
The most reliable chronic endometritis diagnosis is based on immunohistochemistry plasma cell identification in endometrial samples. Our study aimed to compare multiple myeloma oncogene 1 (MUM1) and syndecan-1/CD138 immunohistochemistry staining for chronic endometritis diagnosis among patients with recurrent pregnancy loss. We evaluated the presence of endometrial stromal changes. Fifty-four patients with a history of at least two intrauterine pregnancy losses underwent diagnostic hysteroscopy in the follicular phase of the cycle with endometrial aspiration biopsy. In all 54 cases, three successive sections were cut from each paraffin-embedded tissue block for hematoxylin and eosin (H&E), CD138 and MUM1 staining. The goal was to evaluate the level of agreement between the MUM1 and CD138 results and plasma cell detection rate in assessing the endometrial stromal changes. The concordance analysis between CD138 and MUM1 immunohistochemistry staining showed consistent results in 43 of 54 (79.6%) cases. The level of agreement was moderate, based on a Kappa value of 0.60. MUM1 immunostaining was positive for CE in more cases than CD138 staining, and this difference was statistically significant, showing a higher sensitivity of MUM1 in plasma cell detection (p=0.01). Endometrial stromal changes were observed in the majority of cases - 49/54 (90%). Samples without stromal changes were consistently negative for plasma cells using both CD138 and MUM1 staining. We demonstrated that MUM1 staining, used in conjunction with assessing endometrial stromal changes, contributes to a more accurate and comprehensive diagnosis of chronic endometritis.

Abstract
Two cases of Sporadic Burkitt’s lymphoma in children aged 11 and 8 years with primary symptoms in the oral cavity are reported. The first symptoms of the disease appeared in the oral cavity and were initially misdiagnosed as an inflammatory condition in one case and incidental findings not associated with the primary reason for visiting the dentist’s office in the second case. Biopsies of the lesions revealed the actual cause of the observed changes and contributed to the prompt initiation of polychemotherapy treatment. A review of current literature presents the known symptoms of Burkitt’s Lymphoma in the oral cavity and the available diagnostic methods. The role of the primary care physicians—the pedodontist and paediatrician—in the diagnostic and therapeutic process is discussed.

Abstract
CLN8 is a ubiquitously expressed membrane-spanning protein that localizes primarily in the ER, with partial localization in the ER-Golgi intermediate compartment. Mutations in CLN8 cause late-infantile neuronal ceroid lipofuscinosis (LINCL). We describe a female pediatric patient with LINCL. She exhibited a typical phenotype associated with LINCL, except she did not present spontaneous myoclonus, her symptoms occurrence was slower and developed focal sensory visual seizures. In addition, whole-exome sequencing identified a novel homozygous variant in CLN8, c.531G>T, resulting in p.Trp177Cys. Ultrastructural examination featured abundant lipofuscin deposits within mucosal cells, macrophages, and monocytes. We report a novel CLN8 mutation as a cause for NCL8 in a girl with developmental delay and epilepsy, cerebellar syndrome, visual loss, and progressive cognitive and motor regression. This case, together with an analysis of the available literature, emphasizes the existence of a continuous spectrum of CLN8-associated phenotypes rather than a sharp distinction between them.

Abstract
INTRODUCTION Ghrelin, originally isolated from the endocrine cells of the gastric mucosa, is also expressed in many peripheral tissues, including normal adrenals and adrenocortical tumors. It was shown that ghrelin stimulates proliferation and inhibits apoptosis of adrenocortical cells. In the current study, we compared ghrelin expression at the protein level in various adrenal tumors. We analyzed whether immunoreactive ghrelin could be considered as a potential marker for different types of adrenal tumors. MATERIAL AND METHODS Study was carried out on 200 adrenal specimens arranged on microscope slide in tissue microarray format. We performed standardized immunohistochemical reactions with semiquantitative reaction intensity measurements. RESULTS At the protein level, the expression of ghrelin was significantly reduced in adrenocortical adenocarcinoma in relation to the control group and pheochromocytoma as well as cancer-adjacent normal adrenal tissue. In contrast, a relatively high ghrelin expression was found in pheochromocytoma compared to all analyzed groups, with the exception of cancer-adjacent normal adrenal tissue. CONCLUSIONS The ghrelin expression profile at the protein level may be associated with the type of adrenal tumor. In this context, our results suggest that adrenal immunoreactive ghrelin may be considered as a sensitive and specific marker for differentiating adrenocortical carcinoma from adrenocortical adenoma and pheochromocytoma.

Abstract
Stem cell therapy in combination with genetic modification (e.g., transfection with the coding sequence for the connexion 43 gene, GJA1) may solve the problems associated with the occurrence of additional (secondary) stimulation in the post-infarcted heart (arrhythmia). Human skeletal muscle-derived stem/progenitor cells (SkMDS/PCs) were transfected with the pCiNeo-GJA1 plasmid at an efficiency of approximately 96%. Gene overexpression was assessed using qPCR, and subsequent analysis revealed that GJA1 expression increased more than 40-fold in SkMDS/PCs transfected with the appropriate coding sequence (SkMDS/PCsCX43) compared to that of the 'native' SkMDS/PCs control (SkMDS/PCsWT). Enhanced (4-fold) protein expression of connexin-43 was also confirmed by Western immunoblotting. Furthermore, using the arrhythmic score, we demonstrated the positive effects of SkMDS/PCsCX43 cell intervention in reducing additional secondary stimulations in rat post-infarcted hearts compared with that of wild-type cell delivery. Selected gene responses (Kcnq1, Cacna1c, Ncx1, Serca2a, and Tgfb1) showed significantly altered expression profiles in the rat myocardium upon intervention with SkMDS/PCsCX43. The genetic modification of human skeletal muscle-derived stem/progenitor cells with connexin-43 prevented the pro-arrhythmic effects of myogenic implanted stem cells on the host myocardium and positively influenced myocardial gene expression profiles in respect to myocardium conductivity.

Abstract
Background There is growing evidence that obstructive sleep apnea (OSA) promotes vascular endothelial dysfunction and atherogenesis. Pathways that mediate this pathology may include Toll-like receptors (TLRs) and receptor for advanced glycation end products (RAGE) which play a significant role in proinflammatory processes. The aim of this study was to measure the expression of the above-mentioned receptors in relation to OSA severity in carotid plaques obtained during open endarterectomy. Methods This prospective study included patients with a sleep study prior to surgery and a plaque specimen obtained during standard open endarterectomy. Immunohistochemistry of TLR2, TLR4, TLR7, TLR9, RAGE, HMGB1, and NF-κB was performed on atherosclerotic plaques from carotid arteries of patients with and without OSA. Results There were 46 patients (22 women, mean age 73.2 ± 1.3 years): 14 control patients, 13 with mild, 11 with moderate, and 8 with severe OSA. The expression of all TLRs and RAGE increased proportionately with increasing OSA severity. The largest differences between patients with severe OSA and no OSA were found for TLR2 (2.88 ± 0.35 vs. 1.27 ± 0.47, p < 0.001), TLR4 (2.88 ± 0.35 vs. 1.64 ± 0.5, p < 0.001), TLR9 (2.38 ± 0.52 vs. 1.45 ± 0.52, p < 0.01), and RAGE (2.5 ± 0.53 vs. 1.82 ± 0.6, p < 0.05). Conclusion TLR2, TLR4, TLR9, and RAGE expression was significantly increased in carotid plaques of patients with moderate-to-severe OSA when compared with control patients with no OSA and those with mild OSA. TLR and RAGE-mediated pathways may play a significant role in OSA-dependent atherogenesis.

Abstract
We analyzed three cases of Complete Androgen Insensitivity Syndrome (CAIS) and report three hitherto undisclosed causes of the disease. RNA-Seq, Real-timePCR, Western immunoblotting, and immunohistochemistry were performed with the aim of characterizing the disease-causing variants. In case No.1, we have identified a novel androgen receptor (AR) mutation (c.840delT) within the first exon in the N-terminal transactivation domain. This thymine deletion resulted in a frameshift and thus introduced a premature stop codon at amino acid 282. In case No.2, we observed a nonsynonymous mutation in the ligand-binding domain (c.2491C>T). Case No.3 did not reveal AR mutation; however, we have found a heterozygous mutation in CYP11A1 gene, which has a role in steroid hormone biosynthesis. Comparative RNA-Seq analysis of CAIS and control revealed 4293 significantly deregulated genes. In patients with CAIS, we observed a significant increase in the expression levels of PLCXD3, TM4SF18, CFI, GPX8, and SFRP4, and a significant decrease in the expression of SPATA16, TSACC, TCP10L, and DPY19L2 genes (more than 10-fold, p < 0.05). Our findings will be helpful in molecular diagnostics of patients with CAIS, as well as the identified genes could be also potential biomarkers for the germ cells differentiation process.

Abstract
Ischemic heart disease, also known as coronary artery disease (CAD), poses a challenge
for regenerative medicine. iPSC technology might lead to a breakthrough due to the
possibility of directed cell differentiation delivering a new powerful source of human
autologous cardiomyocytes. One of the factors supporting proper cell maturation is in
vitro culture duration. In this study, primary human skeletal muscle myoblasts were
selected as a myogenic cell type reservoir for genetic iPSC reprogramming. Skeletal muscle
myoblasts have similar ontogeny embryogenetic pathways (myoblasts vs. cardiomyocytes), and
thus, a greater chance of myocardial development might be expected, with maintenance of
acquired myogenic cardiac cell characteristics, from the differentiation process when
iPSCs of myoblastoid origin are obtained. Analyses of cell morphological and structural
changes, gene expression (cardiac markers), and functional tests (intracellular calcium
transients) performed at two in vitro culture time points spanning the early stages of
cardiac development (day 20 versus 40 of cell in vitro culture) confirmed the ability of
the obtained myogenic cells to acquire adult features of differentiated cardiomyocytes.
Prolonged 40-day iPSC-derived cardiomyocytes (iPSC-CMs) revealed progressive cellular
hypertrophy; a better-developed contractile apparatus; expression of marker genes similar
to human myocardial ventricular cells, including a statistically significant
CX43 increase, an MHC isoform switch, and a troponin I isoform
transition; more efficient intercellular calcium handling; and a stronger response to
β-adrenergic stimulation.

Abstract
PURPOSE The present study is to discover a new genes associated with drug resistance development in ovarian cancer. METHODS We used microarray analysis to determine alterations in the level of expression of genes in cisplatin- (CisPt), doxorubicin- (Dox), topotecan- (Top), and paclitaxel- (Pac) resistant variants of W1 and A2780 ovarian cancer cell lines. Immunohistochemistry assay was used to determine protein expression in ovarian cancer patients. RESULTS We observed alterations in the expression of 22 genes that were common to all three cell lines that were resistant to the same cytostatic drug. The level of expression of 13 genes was upregulated and that of nine genes was downregulated. In the CisPt-resistant cell line, we observed downregulated expression of ABCC6, BST2, ERAP2 and MCTP1; in the Pac-resistant cell line, we observe upregulated expression of ABCB1, EPHA7 and RUNDC3B and downregulated expression of LIPG, MCTP1, NSBP1, PCDH9, PTPRK and SEMA3A. The expression levels of three genes, ABCB1, ABCB4 and IFI16, were upregulated in the Dox-resistant cell lines. In the Top-resistant cell lines, we observed increased expression levels of ABCG2, HERC5, IFIH1, MYOT, S100A3, SAMD4A, SPP1 and TGFBI and decreased expression levels of MCTP1 and PTPRK. The expression of EPHA7, IFI16, SPP1 and TGFBI was confirmed at protein level in analyzed ovarian cancer patients.. CONCLUSIONS The expression profiles of the investigated cell lines indicated that new candidate genes are related to the development of resistance to the cytostatic drugs that are used in first- and second-line chemotherapy of ovarian cancer.

Abstract
Cardiovascular diseases are a growing problem in developing countries; therefore, there is an ongoing intensive search for new approaches to treat these disorders. Currently, cellular therapies are focused on healing the damaged heart by implanting stem cells modified with pro-angiogenic factors. This approach ensures that the introduced cells are capable of fulfilling the complex requirements of the environment, including the replacement of the post-infarction scar with cells that are able to contract and promote the formation of new blood vessels that can supply the ischaemic region with nutrients and oxygen. This study focused on the genetic modification of human skeletal muscle cells (SkMCs). We chose myoblast cells due to their close biological resemblance to cardiomyocytes and the placental growth factor (PlGF) gene due to its pro-angiogenic potential. In our in vitro studies, we transfected SkMCs with the PlGF gene using electroporation, which has previously been proven to be efficient and generate robust overexpression of the PlGF gene and elevate PlGF protein secretion. Moreover, the functionality of the secreted pro-angiogenic proteins was confirmed using an in vitro capillary development assay. We have also examined the influence of PlGF overexpression on VEGF-A and VEGF-B, which are well-known factors described in the literature as the most potent activators of blood vessel formation. We were able to confirm the overexpression of VEGF-A in myoblasts transfected with the PlGF gene. The results obtained in this study were further verified in an animal model. These data were able to confirm the potential therapeutic effects of the applied treatments.

Abstract
e20514 Background: Lung cancer is considered the most common cause of death in the world. The prognosis for patients is poor and depends on the clinical stage and the histological type of cancer. There is a need to identify and develop new therapeutic targets that could improve the prognosis of NSCLC patients and may be responsible for development of resistance to TKI therapy. Increased expression of Fn14 or CD44v and EGFR was observed in many tumors and also correlated with the overall survival of NSCLC patients Methods: We analyzed the clinical data and the immunohistochemical expression of Fn14, CD44v and EGFR in tumor tissues from 61 patients with NSCLC divided in two groups according to the presence of activating EGFR gene mutation. The aim of the study was to evaluate the correlation between the expression of the studied molecules and the neoplastic disease course of NSCLC patients. Results: Increased expression of Fn14 was observed in study group (B) compared to expression of this molecule in the control group (K). There were no differences in the intensity of the reaction with anti CD44v and EGFR antibodies in both groups. OS was significantly longer in the study group. Histological grade of tumor correlated with the intensity of CD44v expression in both groups. There was no correlation between the OS and Fn14 expression in any group. Negative correlation was noted between the expression of CD44v and the OS in the study group and between EGFR expression and the OS in both groups. Conclusions: Our observations suggest that the expression of CD44v and EGFR may be useful clinical markers of prognostic value in lung adenocarcinoma patients regardless of the presence of activating mutation in EGFR gene. Simultaneous assessment of Cd44v and EGFR expression may grant a greater prognostic value than the assessment of each receptor separately. Increased expression of Fn14 receptor in patients with EGFR gene mutation may become a new target in therapy allowing to eliminate the problem of secondary resistance to treatment with TKI’s

Abstract
Epithelioid angiomyolipoma (EAML) is a rare mesenchymal neoplasmic variant of angiomyolipoma characterized by aggressive growth and unpredictable outcome. Cases of local recurrence and distant metastasis have been described. The histopathological diagnosis may be difficult, as EAML often mimics other neoplasms. This is the case report of a 39-year-old male patient with EAML, which was initially diagnosed as adrenal cortical carcinoma, due to the lack of cooperation between clinicians and pathologists.

Abstract
The stability-indicating LC assay method was developed and validated for quantitative determination of cefozopran hydrochloride (CZH) in the presence of degradation products formed during the forced degradation studies. An isocratic, RP-HPLC method was developed with C-18 (250 mm x 4.6 mm, 5 µm) column and 12 mM ammonium acetate-acetonitrile (92:8, v/v) as a mobile phase. The flow rate of the mobile phase was 1.0 mL/min. Detection wavelength was 260 not and temperature was 30°C. Cefozopran hydrochloride as other cephalosporins was subjected to stress conditions of degradation in aqueous solutions including hydrolysis, oxidation, photolysis and thermal degradation. The developed method was validated with regard to linearity, accuracy, precision, selectivity and robustness. The method was applied successfully for identification and determination of cefozopran hydrochloride in pharmaceuticals and during kinetic studies.
