Abstract
BACKGROUND Migration has been recognized as an important determinant of child health outcomes including childhood vaccination status. This paper aims to examine the association between parental migration status and a less studied aspect of child immunization outcomes, namely timeliness, within the context of New Zealand (NZ), a country characterized by a substantial proportion of its resident population born overseas. Additionally, the study explored the impact of residential duration on children's immunization timeliness. METHODS The data was taken from a large, representative population-based cohort study in NZ (Growing Up in NZ study). A total of 6156 children and their parents, comprising 2241 foreign-born and 3915 NZ-born mothers and a sub-group of their partners were included in the analysis. The survey data was linked with the National Immunization Register dataset. Timely immunization was defined as receiving two vaccines at each scheduled vaccination point (at six-week, three-month, and five-month, totaling six doses of vaccines) within 30 days of their due date. We examined the associations between parental migration status, maternal residential duration, and child immunization timeliness while controlling for socio-economic variations. The results were presented as adjusted odds ratios (AORs) with 95 % confidence intervals (CIs). RESULTS The findings revealed that after adjustment for socioeconomic differences, children of foreign-born mothers exhibited higher odds of receiving all six studied vaccine doses on time compared to children of native-born mothers (AOR 1.51, 95 %CI:1.27-1.78). Similarly, having a foreign-born father was also significantly associated with timely completion of all six vaccine doses. Children of recent immigrants who had resided in the country for less than five years demonstrated higher odds of timely vaccination of all six vaccine doses compared to children of settled immigrants who had lived in the country for five or more years (AOR 1.65, 95 %CI: 1.25-2.19). CONCLUSION This study revealed a significant pattern in NZ where immigrants exhibited higher rates of timely immunization for their children compared to native-born parents. However, the findings also underscore the importance of providing support to settled immigrants, as their children experienced declines in timely vaccination rates compared to children of recent immigrants and even those born to NZ-born parents.

Abstract
Stem-cell-based therapy is one of the most promising therapeutic strategies owing to its regenerative and immunomodulatory properties. Epigallocatechin-3-gallate (EGCG), a known antioxidant and anti-inflammatory agent, has beneficial effects on cellular protection. We aimed to elucidate the feasibility of using EGCG, along with bone marrow-derived mesenchymal stem cells (BM-MSCs), to improve pancreatic damage through their immune regulatory functions in an experimental model of type 1 diabetes mellitus (T1DM) induced by multiple injections of streptozotocin (STZ). BM-MSCs were isolated from C57BL/6 mice and characterized. The diabetic groups were treated intraperitoneally with PBS, MSCs, EGCG, and a combination of MSCs and EGCG. Real-time PCR assays showed that MSCs with EGCG modulated T-bet and GATA-3 expression and upregulated the mRNA levels of Foxp-3 more efficiently. Analyses of spleen-isolated lymphocytes revealed that combinational treatment pronouncedly increased regulatory cytokines and decreased pro-inflammatory cytokines and splenocyte proliferation. The histopathological assessment demonstrated that co-treatment significantly reduced insulitis and recovered pancreatic islet morphology. Furthermore, the combination of MSCs and EGCG is associated with downregulated blood glucose and enhanced insulin levels. Therefore, combined therapy with EGCG and MSCs holds clinical potential for treating T1DM through synergetic effects in maintaining the Th1/Th2 response balance and promoting the regeneration of damaged pancreatic tissues.

Abstract
Understanding molecular networks of CRLM is an ongoing area of research. In this study, paired CRC tissue and adjacent noncancerous tissue from 15 non-metastatic CRC patients and paired CRC tissue and matched liver metastatic tissues from 15 CRLM patients along with their adjacent noncancerous tissues were evaluated. We assessed Rap1 pathway-related genes including NRAS, FGF-1, NGF, and KDR expression by qRT-PCR and their protein status by Western blot. In CRLM patients, NRAS, FGF1, and KDR mRNA and protein were expressed at higher levels in metastatic than in CRC primary tumor and adjacent noncancerous tissue (p < 0.05). In non-metastatic patients, NRAS, FGF1, KDR, and NGF gene expression did not differ between CRC primary tumor-and adjacent noncancerous tissue (p > 0.05). ROC curve analysis showed a reasonable diagnostic accuracy of NRAS, FGF1, KDR, and FGF for the discrimination of metastatic patients from non- metastatic ones on analysis of their primary tumors. The data suggest that further functional studies on Rap1-related genes' role in CRLM are needed. In conclusion, the present data broaden our knowledge about specific molecular characteristics of CRLM. An increased understanding of the molecular features of metastasis has the potential to create more successful treatment, or prevention, of metastasis, especially in multimodal primary tumor treatment.

Abstract
The triazolobenzodiazepine as a cyclic imine was employed in a variety of Joullié-Ugi reactions, and three new families of unique triazolobenzodiazepine connected to carboxamide and tetrazole products were synthesized via a three-component reaction of the cyclic imine and isocyanides with each species of a carboxylic acid/water/TMSN3 under mild conditions in high yields. Furthermore, triazolobenzodiazepine imine was used in an interesting strategy based on the modified Ugi reaction (pseudo-Joullié-Ugi reaction) of cyclic imines with an isocyanide and acetylenedicarboxylates under catalyst-free conditions for the synthesis of triazolobenzodiazepine-fused pyrroles. Mechanistic investigation reveals that triazolobenzodiazepine-fused pyrroles have been generated via a surprising route. Significantly, the use of triazolobenzodiazepine in the Joullié-Ugi, azido-Joullié-Ugi, and pseudo-Joullié-Ugi reactions of a broad scope of biological scaffolds occurred under mild, simple conditions without any catalyst.

Abstract
In recent decades the entangled state generation is of great importance in the quantum information processing and technologies. In this paper, producing the distributed entangled state of superconducting (SC) qubits is considered using an entanglement swapping protocol in three successive stages. The SC qubit pairs [Formula: see text] with [Formula: see text], where each pair of the qubits has been placed on a separate chip, are initially prepared in maximally entangled states. The external magnetic fields on capacitively coupled pairs [Formula: see text] and [Formula: see text] are implemented for modulating the frequency of qubits. Then, the SC qubits [Formula: see text] and [Formula: see text] are converted into entangled states via operating proper measurements instead of Bell state measurement (which is generally a hard task). Finally, the distributed entangled state of target SC qubits [Formula: see text] can be obtained by applying external magnetic fields on qubits [Formula: see text] and via operating suitable measurements. This process is studied in the absence and presence of thermal decoherence effects. The concurrence, as a measure of entanglement between two target qubits, success probability of the distributed entangled states and the corresponding fidelities are evaluated, by which we find that the state of target SC qubits [Formula: see text] is converted to Bell state with maximum entanglement at some moments of time. Under appropriate conditions the maximum of success probability of the obtained states in each stage approaches 1. However, the maxima of concurrence and success probability gradually decrease due to the thermal noise as time goes on. Moreover, compelling amounts of fidelity, success probability and entanglement can be obtained for the achieved entangled states.

Abstract
INTRODUCTION AND IMPORTANCE Splenogonadal fusion is a rare congenital anomaly occurs when splenic tissue presents near or within a gonad. It mostly involves male children. Although it is benign and rare, making a pre-operation precise diagnosis is challenging which can lead to unnecessary invasive treatments. CASE PRESENTATION A 3-year-old boy was presented by the chief complaint of a painless mass on the left testis and left inguinal hernia. He had a previous history of bilateral cryptorchidism and orchiopexy. Ultrasonography showed a small mass on the inferior pole of left testis and left reducible inguinal hernia. He went under left orchiectomy and hernia repair. Pathological investigation of the specimen resembled normal splenic tissue next to testicular tissue and the diagnosis of splenogonadal fusion was made. CLINICAL DISCUSSION Splenogodal fusion cases can be challenging. Pain and sensation of mass in the scrotal sac are the most common presentation of splenogonadal fusion. Testicular malignancies can be considered as their main differential diagnosis, despite the fact that imaging and intra-operation frozen section can be helpful in making a definite diagnosis in some cases. It is mostly diagnosed incidentally during other procedures such as hernia repair or orchiopexy. Since it is benign, removal of tumor without orchiectomy is curative. CONCLUSION In dealing with testicular mass in children, raising awareness of splenogonadal fusion have utmost importance to prevent unnecessary radical surgical interventions.

Abstract
Exposure to arsenic is linked to a wide range of diseases, in particular male reproductive toxicities. Trametes versicolor is a traditional medicinal fungus with a remarkable potential for antioxidant activity. The purpose of this study was to examine the ameliorating effects of water and methanol extracts of T. versicolor on arsenic-induced male reproductive toxicities via the abrogation of oxidative stress. The mice were divided as follows: control: normal saline, As: arsenic (15 mg/kg), WE: water extract (400 mg/kg), ME: methanol extract (400 mg/kg), As + WE: arsenic (15 mg/kg) + water extract (100, 200, 400 mg/kg), As + ME: arsenic (15 mg/kg) + methanol extract (100, 200, 400 mg/kg), and positive control: arsenic (15 mg/kg) + vitamin C (500 mg/kg). Animals were treated via the intraperitoneal route. About 24 hr later, the mice were euthanized, and oxidative stress parameters (reactive oxygen species [ROS], lipid peroxidation, glutathione concentration, protein carbonylation, glutathione peroxidase, and superoxide dismutase activity), histopathological changes and sperm parameters (count, motility, and morphology) were examined in the testicular tissue. Arsenic caused significant pathological changes in the testicular tissue and sperm morphology and significantly reduced sperm count and motility. Moreover, arsenic mediated oxidative stress via significant increases in ROS generation, lipid peroxidation, and protein carbonyl content, as well as significant depletion in glutathione concentration and superoxide dismutase and glutathione peroxidase activities. Although, coadministration of water and methanol extracts of T. versicolor at 200 and 400 mg/kg counteracted arsenic-induced oxidative and histopathological damages and improved sperm parameters. Our study indicated that T. versicolor ameliorated arsenic-induced testis toxicity and sperm dysfunction via attenuation of oxidative damage.

Abstract
BACKGROUND Over the past few years, mesenchymal stromal cells (MSCs) have attracted a great deal of scientific attention owing to their promising results in the treatment of incurable diseases. However, there are several concerns about their possible side effects after direct cell transplantation, including host immune response, time-consuming cell culture procedures, and the dependence of cell quality on the donor, which limit the application of MSCs in clinical trials. On the other hand, it is well accepted that the beneficial effects of MSCs are mediated by secretome rather than cell replacement. MSC secretome refers to a variety of bioactive molecules involved in different biological processes, specifically neuro-regeneration. MAIN BODY Due to the limited ability of the central nervous system to compensate for neuronal loss and relieve disease progress, mesenchymal stem cell products may be used as a potential cure for central nervous system disorders. In the present study, the therapeutic effects of MSC secretome were reviewed and discussed the possible mechanisms in the three most prevalent central nervous system disorders, namely Alzheimer's disease, multiple sclerosis, and Parkinson's disease. The current work aimed to help discover new medicine for the mentioned complications. CONCLUSION The use of MSC-derived secretomes in the treatment of the mentioned diseases has encouraging results, so it can be considered as a treatment option for which no treatment has been introduced so far.

Abstract
A novel and unexpected route for synthesizing pyrrole-fused dibenzoxazepines/thiazepines has been designed based on a modified Ugi reaction of cyclic imines with isocyanides and acetylenedicarboxylates under catalyst-free conditions. Mechanism investigation indicates that this process is carried out through the production of zwitterion species (Huisgen's 1,4-dipole), which is a key intermediate in the chemoselectivity of products. This Huisgen's 1,4-dipole is trapped in situ with isocyanides and a variety of pyrrole-fused dibenzoxazepines/thiazepines are synthesized in a simple one-pot operation with high yields and chemoselectivity. This strategy opens a new route in Ugi reactions (pseudo-Joullié-Ugi reaction) for the synthesis of pyrrole-fused heterocycles as special pharmaceutical scaffolds.

In this research, an efficient, fast, low-cost and easy-to-use liquid-phase microextraction method was established to measure quercetin in onion and tomato before analysis by HPLC instrument. Herein, a rotatable central composite design-response surface methodology and artificial neural network were applied to model, optimize and predict the affecting factors on the microextraction procedure. Here, a minimal level of extractant was applied in the absence of a disperser. The cloudy state was formed by repeatedly suctioning and injecting the mixture of the aqueous solution and extractant with a glass syringe. Due to this procedure, a turbid solution composed of the very fine droplets of extractant dispersed in the aqueous solution was created, the contact surface was significantly enlarged and the quercetin was promptly extracted. The optimum values for the proposed method included 284 μL of 1-undecanol as the organic extractive solvent, pH of sample 3.3, the number of air injected nine times and speed and duration of centrifugation 4,000 rpm and 5 min. The linear range and detection of limit were achieved at 20-4,000 and 6 μg L-1, respectively. RSD% was obtained ˂4.93% (n = 5). This model was applied to monitor quercetin in tomato and onion samples.

Abstract
The main purpose of this study is to synthesize and characterize Persian gum-based hydrogel composited with gentamicin (Gen)-loaded natural zeolite (Clinoptilolite) and to evaluate its biological properties. Clinoptilolite (CLN) was decorated with Gen, and the conjugation was confirmed using computational and experimental assessments. The Monte Carlo adsorption locator module was used to reveal the physicochemical nature of the adsorption processes of Gen on CLN and ALG and gum on Gen@ CLN in Materials Studio 2017 software. Based on the high negative results, the adsorption process was found to be endothermic in all studied cases, and the interaction energies were in the range of physisorption for Gen on CLN and ALG and gum on Gen@CLN. Dynamic light scattering (DLS) and zeta potential analysis showed that the size of pristine CLN was around 2959 nm and the conjugation decreased the size significantly to approximately 932 nm. The hydrogel characterizations showed that the Gen-decorated CLNs are homogenously dispersed into the hydrogel matrix, and the resultant hydrogels have a porous structure with interconnected pores. The release kinetics evaluation showed that around 80 % of Gen was released from the nanocomposite drug during the first 10 h. In vitro studies revealed hemocompatibility and cytocompatibility of the nanocomposite. Microbial assessments indicated dose-dependent antibacterial activity of the hydrogel against gram (+) and gram (-) bacteria. The results showed that the fabricated hydrogel nanocomposite exhibits favorable physicochemical and biological properties.

Abstract
Abstract
Purposes
Calcium channel blockers, such as diltiazem (DLZ), are important drugs for wound repair treatment. This current study used an ultrasonic method to increase the cutaneous delivery of (DLZ) niosomes.
Methods
The impact of the cholesterol:surfactant ratio on the DLZ-loaded niosome formulations was investigated. Differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, drug release, skin sensitivity, animal wound repair model, and histopathological assessment were applied to investigate the characteristics, morphology, and therapeutic effectiveness of the DLZ noisome.
Results
The results showed that changes in the cholesterol:surfactant ratio can influence the zeta potential and the size of the niosome. The maximum entrapment efficiency was observed to be about 94% when the cholesterol content in the formulation was high. The DLZ release studies revealed that the niosomal formulation was released slowly over the course of 24 h. Macroscopic observations of the wound demonstrated that wound closure in the DLZ-niosome-treated group and the commercial brand was equal and higher than in the other groups (gel base, placebo gel, and negative control). Pathological studies described that the wound repair in the DLZ-niosomal gel group was greater than in the other treatment. All the preparations tested for cutaneous irritation on Wistar rats showed the DLZ niosomal gels to be non-irritating.
Conclusion
The findings of this study revealed that the prepared DLZ-niosome could be used as a possible nano-vesicle for DLZ cutaneous delivery thus potentially opening up new prospects for the treatment of wound disorders.

Abstract
Introduction Subacute thyroiditis (SAT), also known as de Quatrain's thyroiditis or granulomatous thyroiditis, is an inflammatory disease of the thyroid. Most of the time, it manifests in the thirties to fifties and is more common in women. SAT can have either viral or post-viral origin. Some viruses, like influenza, COVID-19, Epstein-Barr virus, cytomegalovirus, hepatitis, coxsackievirus 16, and mumps virus, have been linked to SAT development. The COVID-19 pandemic has affected people's lives all around the world and has changed our attitude toward the treatment of many diseases. It has also made us look deeper into the subject in a way that we would be able to treat this sort of disease with a newer insight. Objective Regarding the importance of this issue, we decided to summarize our extensive searches from online databases, including PubMed, Google Scholar, Medline, Web of Science, and Scopus until February 2023, which we found effective in elucidating the association of subacute thyroiditis and viral diseases. Method Different online databases were searched for narrative review articles, systemic review articles, and original articles, which were published until February 2023. Result According to the included studies, we found that there is a correlation between SAT and several viruses such as Epstein-Barr virus, influenza virus, human immunodeficiency virus, cytomegalovirus, oral and cervical virus, hepatitis, dengue virus, and SARS-COV-2. The effect of each of the viral diseases mentioned in the SAT is given in the text. Conclusions According to the results mentioned in the text, because SAT may be challenging for early diagnosis, due to the potential of classic symptoms as well as the interference of similar clinical symptoms between thyrotoxicosis and viral reactions, the correlation between SAT and viral diseases should be considered so that we can avoid misdiagnosis and lateness.

Abstract
An individual with a genetic predisposition to inflammatory bowel disease (IBD) can experience inflammatory responses leading to conditions such as Crohn's disease (CD) or Ulcerative colitis (UC). Currently, stem cell therapies, particularly those utilizing mesenchymal stem cells (MSCs), are gaining attention due to their immunomodulatory properties, as demonstrated in clinical trials. Consequently, we decided to investigate the effects of mesenchymal stem cells-conditioned medium (MSC-CM) and Abatacept in an experimental model of acute colitis. MSC-CM was extracted from female BALB/C mice and stored for future use. Acute colitis was induced in BALB/C mice through the intrarectal administration of 100 µL of 4% acetic acid. Following this procedure, CM and Abatacept were administered intraperitoneally. Throughout the study, various parameters were monitored, including changes in body weight, bleeding, stool consistency, disease activity index (DAI), mortality rate, as well as the weight and length of the colon. Histopathological analyses were also conducted, along with monitoring changes in the levels of IL-10 and IFN-γ. The data collected are presented as mean ± SD and were analyzed using One-Way ANOVA. According to the results of the study, CM with and without Abatacept significantly reduced weight loss and bleeding as well as improved fecal consistency and DAI. Macroscopic examination of the colon showed that after infusion, colon length was reduced and histopathological analysis showed a decrease in mucosal changes. The secretion of IL-10 was increased while the IFN-γ level was reduced. Research indicates that the immunomodulatory properties of MSC secretion can have positive effects. We propose a combination therapy with MSC, which we believe could lead to improved outcomes in the treatment of acute colitis.

Abstract
The aim of this study was to evaluate the cytotoxicity and immune-stimulatory
effect of Mesoporous silica nanoparticle (MSN) Nano-adjuvant on pro-inflammatory
cytokines and pattern recognition receptors (PRR) genes expression in
Caco-2/PBMC co-culture model. MSNs were synthesized and characterized by
scanning electron microscope (SEM), Brunauer Emmett Teller (BET) and Barrett
Joyner Halenda (BJH) techniques. The BET specific surface area of MSNs was
around 947 m2/g and the total pore volume and average pore diameter
were 1.5 cm3/g and 8.01 nm, respectively. At the concentration of
10 µg/mL, MSN showed a low and time-dependent cytotoxicity on Caco-2 cells,
while no cytotoxic effect was observed for 0.1 and 1 µg/mL concentrations after
24, 48 and 72 h. The expression of pro-inflammatory cytokines genes (IL-1, IL-8
and TNF-α) in co-cultures treated with different concentrations of MSN showed a
dose-dependent significant increase up to 17.44, 2.722 and 4.34 folds,
respectively, while the expression augmentation of IL-1 gene was significantly
higher than the others. This indicates slight stimulation of intestinal
inflammation. Different concentrations of MSN significantly increased TLR4 and
NOD2 expression to 4.14 and 2.14 folds, respectively. NOD1 was not affected
significantly. It can be concluded that MSN might increase protective immune
responses against antigens as a vaccine adjuvant candidate. It seems that
stimulation of TNF-α, IL-1, and IL-8 expression in enterocytes probably
transpires through the agonistic activity of MSN for TLRs including TLR4, while
NOD2-associated signaling pathways are also involved. This study provides an
overall picture of MSN as a novel and potent oral adjuvant for mucosal
immunity.

Abstract
BACKGROUND Lipoid Proteinosis (LP) or Hyalinosis Cutis et Mucosae or Urbach-Wiethe disease is a rare autosomal recessive genodermatosis characterized by an amorphous hyaline material deposition in the skin mucosa and viscera. The clinical symptoms of this disease often begin in childhood, which persist throughout life. Skin manifestations include inflammation, scaling, acne, and eventually ulceration, and hyaline amorphous deposits in these areas of the wound cause a waxy and thick appearance on the skin. In addition, wounds leave atrophic scars like chickenpox. AIM Herein, we present the first case of LP in the north of Iran; although LP is a sporadic disease, it occurs all around the world, with about 400 cases worldwide having been reported thus far. PATIENT We report the case of a 28-year-old female with a history of skin lesions on her face, scalp, extremities, and buttock, as well as hoarse cry, respiratory problems, dysphagia, and migraine since childhood. There was no evidence of other clinical presentations. A biopsy was taken from the lesions, and the patient was diagnosed with LP. A laryngeal laser was performed for the patient, and peeling creams were used for her skin lesions. RESULT According to previous findings, there has been no case report of LP with systemic symptoms in the north of Iran.

Abstract
Acoustic droplet vaporization (ADV) is a new approach to generate vapor bubbles that have potentially broad medical applications. ADV-generated bubbles can be used as contrast agents in acoustic imaging, as drug carriers to deliver drugs to particular targets, and also in embolotherapy, thermal therapy, and histotripsy. However, despite much progress, ADV dynamics have still not been well understood and properly modeled. In this paper, we present a theoretical study of ultrasound-induced evaporation of a droplet encapsulated by a shell. The main emphasis of this theoretical study is on a proper description of the supercritical state occurring after bubble collapse. For this purpose, an isentropic equation of state for a van der Waals gas is used to describe the bubble behavior in the supercritical state. Sensitivity of the vaporization process is investigated for different acoustic and geometrical parameters and mechanical properties of the shell. Results show that the value of the minimum pressure required for direct vaporization (without any oscillatory behavior) depends on shell elasticity and initial size of the droplet, especially at high frequencies (greater than 2[MHz]). Moreover, it has been shown that applying an acoustic wave with proper phase such that thermal equilibrium of the bubble temperature with the surrounding liquid is attained, results in direct vaporization at lower acoustic pressure.

Abstract
Introduction: Hand hygiene is a significant strategy in preventing and controlling infections with a great impact on nosocomial infections and preventing microbial resistance. Objectives: The main goal of this study was to investigate the performance of medical interns in handwashing in the educational and medical centers of Guilan University of Medical Sciences. Patients and Methods: This is a cross-sectional study, which was conducted in 2020 in Rasht city. The study population consisted of all medical interns. The handwashing was observed in medical interns after obtaining their permission and separately at a suitable time and place. They were given a grade based on a poster approved by the Ministry of Health of Iran. Results: A total number of 147 medical interns were enrolled in this study. We also found out that the mean score of study population in handwashing steps was 7.11± 1.97. The lowest rate of correct performance was for 5th (tying the fingertips and washing them) (32%), 8th (washing around the wrist) (49.7%) and 7th (washing the palm lines with the fingertips) (53.1%) steps. The performance score of female interns had a higher average than male interns (7.4 versus 6.8) (P=0.028). Conclusion: Considering the importance of handwashing in preventing the transmission of diseases, especially in the COVID-19 pandemic and the repeated recommendations to wash hands properly as a simple and accessible way to prevent further transmission of the virus, the review of the awareness and practice of medical interns about the handwashing seems to be critical.

Abstract
Valproic acid (VPA) is widely used antiepileptic agent which is associated with reproductive toxicity via impairment in oxidative redox. Zinc (Zn) and selenium (Se) are trace element with antioxidant effect that known to be essential for spermatogenesis. In the current study, the protective effect of co-administration of Zn and Se on VPA-induced reproductive toxicity in male rats was evaluated. Forty-eight male rats were divided into 8 groups of six (n=6): Control group (treated with normal saline); VPA only (250, 500, 1,000 mg/kg) group; VPA (500 mg/kg) plus Zn (2 mg/kg) group; VPA (500 mg/kg) plus Se (1.5 mg/kg) group; VPA (500 mg/kg) plus a combination of Zn and Se group; and VPA+vitamin E (20 mg/kg) group. The Animals were sacrificed after 28 days of treatment and sperm analysis was taken. Also, evaluation of oxidative stress markers including malondialdehyde (MDA), protein carbonyl (PC), glutathione (GSH) and histopathological changes were done on testis tissue. Morphological changes and a significant decrease in motility and sperm count in rats treated with VPA were observed. Also, an increase in oxidative stress marker, including MDA and PC and a decrease in GSH level was evident in VPA group. Zn and Se administration was able to protect against sperm abnormality, ameliorate the histological change in testis tissue, and suppressed the increase in oxidative stress markers induced by VPA. These results indicated that combination therapy with Zn and Se showed better an ameliorative effect than each one alone. Therefore, it can be suggested as an effective supplement for reproductive impairment in VPA-treated patient.

Abstract
Background: Cerebrovascular Accident (CVA) is the second cause of death and disability in the world. Heart failure can co-occur with CVA and increases the risk of death and disability in patients. Objectives: This study aimed to evaluate the prevalence of heart failure in patients with ischemic stroke. Materials & Methods: In this cross-sectional study, the information of patients with ischemic stroke was collected in 2016 from their files. They were referred to the Emergency Department of Poursina Hospital. Statistical analysis of data was performed by using descriptive statistical methods. Estimation of mean and frequency was done by SPSS v. 22. Results: A total of 291 patients were recruited in the study. Also, 157 patients (54%) were male, and 134 (46%) were female. The Mean±SD age of patients was 61.68 (12.98) years. Systolic heart failure prevalence was 59.8%, and diastolic heart failure was 65.7%. Conclusion: Based on the findings, more than half of the patients with ischemic stroke also develop heart failure. Therefore, it is recommended that the patient be evaluated and treated for heart failure when faced with ischemic stroke.

Abstract
Introduction: Digital clubbing (hypertrophic osteoarthropathy) as the initial presentation of lymphoma is rarely reported, particularly in children. In this study, we report a patient with intrathoracic Hodgkin Disease (HD) and digital clubbing as the first presentation, and we will review the literature regarding the same condition. Case Presentation: A 10-year-old boy presented with a 2-month history of cough, mild dyspnea, and night sweats, with prominent digital clubbing. A chest x-ray and a computed tomography scan of the chest showed multiple mediastinal masses. A mediastinal lymph node biopsy was done. Pathologic examination was indicative of nodular sclerosis HD. Conclusions: In patients with digital clubbing, intrathoracic malignancies should be considered a differential diagnosis and must be ruled out by precise examination and paraclinical help.

Abstract
The aim of this study was to assess the modulatory effect of TcpA in the expression of CEACAM1 adhesin molecule and IL-1, IL-8, and TNF-α pro-inflammatory cytokines in the Coculture model of Caco-2/PBMC (peripheral blood mononuclear cell) that can mimic the intestinal milieu. The TcpA gene from Vibrio cholerae ATCC14035 was cloned in pET-28a and transformed into Escherichia coli Bl-21. The recombinant TcpA-His6 protein was expressed and purified using Ni-column chromatography. The sequencing of transformed plasmid and Western blot analysis of purified protein confirmed the identity of rTcp. The cytotoxicity of different concentrations of recombinant protein for human colon carcinoma cell line (human colorectal adenocarcinoma cell [Caco-2 cell]) was assessed by MTT assay and showed viability of 92%, 82%, and 70%, for 10 µg/mL of TcpA after 24, 48, and 72 h, respectively. Co-cultures of Caco-2 and PBMCs were used to mimic the intestinal milieu and treated with different concentrations of rTcpA (1, 5, 10, and 50 µg/mL). Our data showed about 2.04-, 3.37-, 3.68-, and 42.7-fold increase in CEACAM1 gene expression, respectively, compared with the nontreated Caco-2/PBMC Coculture. Moreover, the expression of IL-1, IL-8, and TNF-α genes was significantly increased up to 15.75-, 7.04-, and 80.95-folds, respectively. In conclusion, V. cholerae TcpA induces statistically significant dose-dependent stimulatory effect on TNF-α, IL-,1, and IL-8 pro-inflammatory cytokines expression. Of these, TNF-α was much more affected which, consequently, elevated the CEACAM1 expression level in IECs. This suggests that TcpA protein is a critical effector as an inducer of increased adhesion potential of V. cholera as well as inflammatory responses of host intestinal tissue.

Abstract
Measurements of spinal segment ranges of motion (RoMs), movement coordination, and three-dimensional kinematics during occupational activities have implications in occupational/clinical biomechanics. Due to the large amount of adipose tissues, obese individuals may have different RoMs, lumbopelvic coordination, and kinematics than normal-weight ones. We aimed to measure/compare trunk, lumbar, and pelvis primary RoMs in all anatomical planes/directions, lumbopelvic ratios (lumbar to pelvis rotations at different trunk angles) in all anatomical planes/directions and three-dimensional spine kinematics during twelve symmetric/asymmetric statics load-handling activities in healthy normal-weight and obese individuals. Kinematics/motion data were collected from nine healthy young male normal-weight and nine age/height/sex matched obese individuals via a ten-camera Vicon motion capture system. Obese individuals had significantly smaller (p < 0.05) lumbar flexion (~9° in average) and larger pelvis right lateral bending (~5°) RoMs as well as smaller lumbopelvic ratios (~37%) in lateral bending and axial rotation movements as compared to normal-weight individuals. Moreover, the two groups had generally non-significant different segmental orientations (<20° and in most cases < 10°) in load-handling tasks that depended on the magnitude of load asymmetry angle (p < 0.05). Differences were larger for tasks performed near the floor, away from body, and at larger load asymmetry angles. Biomechanical models simulating pure lateral bending, axial rotation, or tasks involving large load asymmetry may therefore need subject-specific, rather than population-based, motion analysis due to the effects from body weight. In clinical applications, it should be noted that healthy obese individuals may have different RoMs and lumbopelvic rhythms than healthy normal-weight individuals in some anatomical planes/directions.

Abstract
Retinoblastoma is known as childhood rare malignancy of the retina. Ciliary neurotrophic factor (CNTF) was previously found to reduce degeneration and promote retina survival. This work investigated the effects of CNTF supplementation on in-vitro model cells including retinoblastoma (Y79) and adipose-derived mesenchymal stem cells (AMSCs) viability, proliferation, gene expression and cell cycle. A drop of viability was detected in Y79 treated with CNTF in a dose-dependent manner (P < .05). However, the proliferation of AMSCs was increased at lower concentrations of CNTF (5 ng/mL), but declined in higher doses (50 and 100 ng/mL). The BrdU assay confirmed the MTT assay results. Cell cycle was arrested in both Y79 and AMSCs in the G0/G1 phase by CNTF treatment. A considerable down-regulation of Bcl2, CycD1 and N-Myc genes expression (P < .05) inversely, P15 and P21 genes up-regulation in treated Y79 cells was observed. Besides, stemness genes' transcription was reduced in AMSCs (P < .05), and levels of neuronal-specific markers such as neuron-specific enolase (NSE) and neuronal nuclei (NeuN) were increased (P < .05). The findings of this study suggest a promising potential of CNTF in terms of arresting Y79 retinoblastoma cells, and differentiation-inducing to AMSCs, which could be valuable for managing future innovative treatments targeting retinoblastoma. SIGNIFICANCE OF THE STUDY: We demonstrate that CNTF has the potential to reduce proliferation of Y79 cells and induce the cell cycle arrest of them. Also, down-regulation of oncogenes (such as N-Myc) while up-regulation of tumour suppressor genes (such as P21) was detected by exposure of Y79 cells to CNTF. Furthermore, we observed the cell cycle arrest, reduction of stemness gene and up-regulation of neural differentiation markers in AMSCs treated with CNTF. These results support the probable promising effects of CNTF for controlling retinoblastoma.

Abstract
One of the most common nutritional deficiencies worldwide is iron deficiency. Fatigue, pallor, vertigo, dyspnea, cold intolerance, lethargy, palpitation, headache, and the pallor of the mucous membranes or nail beds are the most frequent symptoms and signs of iron deficiency. Thrombocytosis is commonly observed in iron deficiency anemia; it seems that erythropoietin plays the main role in this respect. Furthermore, thrombocytopenia and even leukopenia have been reported in iron deficiency; however, pancytopenia is a very rare condition. In this report, we presented two unusual cases of pancytopenia due to severe iron deficiency that improved after treatment with oral iron supplements. Iron deficiency anemia, if sufficiently severe, may be associated with reduced platelet and leukocyte counts. Accordingly, this condition should be considered as a differential diagnosis in all patients with pancytopenia.

Abstract
Reducing the duration of wound healing is important to decrease the chance of infection. Insulin as a peptide hormone has a role in wound healing. Also, the use of clindamycin in the treatment of skin wounds has been studied very little. The aim of this study was to evaluate the synergistic effect of insulin and clindamycin on full-thickness wound healing. In this study, 24 Wistar rats (weight 180-200 g) were randomly divided into four equal groups: control (Eucerin), clindamycin, insulin, and insulin + clindamycin. Drugs were administered in the form of an ointment daily for twelve days. Wound healing rate and wound criteria such as epithelialization, neovascularization, collagen deposition, inflammation, and tissue granulation were investigated histologically on days 3, 7, and 14. The wound healing rate in the insulin + clindamycin group was significantly higher than the other groups on day 7 but there was no significant difference between groups on day 14. In addition, the combination of insulin and clindamycin had a beneficial effect on reducing inflammation and increasing collagen deposition, fibroblast maturation, neovascularization, and keratinization. The data showed that the topical application of insulin with clindamycin has an effective role in full-thickness wound healing by reducing inflammation and accelerating wound closure.

Abstract
In this paper, the implementation of artificial neural networks (multilayer perceptron [MLP] and radial base functions [RBF]) and the upgraded Markov chain model have been studied and performed to identify the human behavior patterns during rock, paper, and scissors game. The main motivation of this research is the design and construction of an intelligent robot with the ability to defeat a human opponent. MATLAB software has been used to implement intelligent algorithms. After implementing the algorithms, their effectiveness in detecting human behavior pattern has been investigated. To ensure the ideal performance of the implemented model, each player played with the desired algorithms in three different stages. The results showed that the percentage of winning computer with MLP and RBF neural networks and upgraded Markov model, on average in men and women is 59%, 76.66%, and 75%, respectively. Obtained results clearly indicate a very good performance of the RBF neural network and the upgraded Markov model in the mental modeling of the human opponent in the game of rock, paper, and scissors. In the end, the designed game has been employed in both hardware and software which include the Zana intelligent robot and a digital version with a graphical user interface design on the stand. To the best knowledge of the authors, the precision of novel presented method for determining human behavior patterns was the highest precision among all of the previous studies.

Abstract
Background & Objective: Galectin-8 has relationships with cell growth and metastasis of some cancers. Due to controversy in the clinical significance of this protein in the cancer process, we investigated its roles in the development of head and neck squamous cell carcinoma. Methods: This study was performed on 93 samples of patients with Squamous Cell Carcinoma or dysplasia of the head and neck, who underwent biopsy or surgery from 2015 till 2017 in Boo-Ali SINA hospital of Sari, Iran. The relevant paraffin embedded tissue blocks were obtained from archive of pathology and evaluated for galectin-8 by immunohistochemistry. The association between expression of galactin-8 and age, sex, location and stage of disease were assessed. To compare expression rate between the groups, Mc-Nemar, Chi-square and Fisher's exact tests were used. The P-value<0.05 was considered significant. Results: Strong cytoplasmic and nuclear galactin-8 staining was observed in 97.6% cases of normal tissues while 77% of dysplastic lesions and 69% of the cancers revealed negative immunoreactivity. The intensity of expression in dysplastic and malignant tissues was significantly reduced compared with normal tissues (P=0.0001). The expression of galectin-8 did not correlate with stage (P=0.303), lymph node involvement (P=0.326), tumor grade (P=0.769), distant metastasis (P=0.748), and age (P=0.574). Conclusion: We observed that the expression of galectin-8 in dysplastic and malignant squamous epithelium significantly reduced compared with the normal counterpart of them in the head and neck. It may contribute to malignant transformation of head and neck squamous cells.

Abstract
Background Baboon syndrome is a rare, type IV hypersensitivity reaction causing a maculopapular rash. Tamoxifen is an antineoplastic agent, working as an estrogen receptor antagonist, also called a selective estrogen receptor modulator. A variety of rashes were reported with Tamoxifen use to‐date except baboon syndrome. The Tamoxifen‐induced baboon syndrome seems to be reversible, as discontinuation of the drug improves clinical outcomes. Aim Herein, we present the first case of Tamoxifen‐induced baboon syndrome which occurred 8 years after initiation of Tamoxifen use. Patients A 44‐year‐old woman presented with papulovesicular eruption on her body and erythema on her face for a duration of 6 months. There was no evidence of ocular or mucosal involvement. She was diagnosed with breast cancer and treated with tamoxifen 10 mg twice daily over the past 8 years. She was not taking other medications or over‐the‐counter supplements at the time of presentation. The patient underwent urgent skin biopsies of two lesions on her buttock and thigh. No organisms were seen on Gram stain. The patient's skin biopsy revealed extensive hyperorthokeratosis, minimal parakeratosis, hypergranulosis, and lichenoid interface dermatitis in the irregularly acanthotic epidermis supporting diagnosis of fixed drug eruption. Following a multidisciplinary discussion, the patient was diagnosed with baboon syndrome or symmetrical drug‐related intertriginous and flexural exanthema (SDRIFE) associated with Tamoxifen. Results Hence, Tamoxifen was immediately discontinued and treated with oral steroid along with topical agents. She showed improvement of clinical abnormalities within days after discontinuation of Tamoxifen. Conclusions Given the widespread use of Tamoxifen in the management of patients with breast cancer, it is important that healthcare professionals monitor for rare, however clinically significant, and potentially life‐threatening dermatological manifestations of Tamoxifen use, such as baboon syndrome.

Abstract
Introduction: Eradication of Pseudomonas aeruginosa has become increasingly difficult due to its remarkable capacity to resist antibiotics. Bacteriophages have been suggested as an alternative treatment for bacterial infections. Methods: In-situ gel-forming eye drop containing phage against P. aeruginosa keratoconjunctivitis was prepared. The Cystoviridae phage was formulated as in-situ gel-forming formulation which is a solution formulation but turns into gel when it contacts the eye. Therapeutic effectiveness of the in-situ gel forming formulation was evaluated by histological examination on day 12 post-infection. Results: The viscosity of selected formulation increased when it was instilled into the eye. The histological results showed edema, abscesses, and destruction of the stromal structure of cornea in groups where no in-situ gel-forming formulation was used. In the group where in-situ gel forming formulation was used, re-epithelialization and normal corneal structure were observed. Conclusion: In-situ gel-forming ophthalmic formulation containing phage can be effective in the treatment of P. aeruginosa keratoconjunctivitis.

Abstract
Abstract
Background
Non-invasive fractional flow reserve (NiFFR) is an emerging method for evaluating the functional significance of a coronary lesion during diagnostic coronary angiography (CAG). The method relies on the computational flow dynamics and the 3D reconstruction of the vessel extracted from CAG. In the present study, we sought to evaluate the diagnostic performance and applicability of 2D-based NiFFR.
Methods
In this prospective observational study, we evaluated 2D-based NiFFR in 279 candidates for invasive CAG and invasive FFR. NiFFR was calculated via 2 methods: variable NiFFR, in which the contrast transport time was extracted from the angiographic view, and fixed NiFFR, in which a prespecified frame count was applied.
Results
The final analysis was performed on 245 patients (250 lesions). Variable NiFFR had an area under the receiver operating characteristic curve of 81.5%, an accuracy of 80.0%, a sensitivity of 82.2%, a specificity of 82.2%, a negative predictive value of 91.4%, and a positive predictive value of 63.6%. The mean difference between FFR and NiFFR was −0.0244 ±0.0616 (P≤0.0001). A pressure wire-free hybrid strategy was possible in 68.8% of our population with variable NiFFR.
Conclusions
Our 2D-based NiFFR yielded results comparable to those derived from 3D-based software. Our findings should, however, be confirmed in larger trials.

Abstract
Background: Intravenous (IV) recombinant tissue Plasminogen Activator (rtPA) (IV-rtPA) is the only FDA-approved pharmacological therapy for treatment in acute ischemic stroke and the administration of IV-rtPA is crucially time-dependent. Objectives: This study aimed to evaluate symptom-to-needle time and factors associated with the prehospital delay in patients with acute ischemic stroke referred to Poursina Hospital, a referral hospital in the north of Iran. Materials & Methods: In this cross-sectional study, all patients with acute stroke referred to Poursina Hospital from June to December 2016 were evaluated. The study data were extracted from the patients’ records. SPSS v. 21 was used to analyze the obtained data. The independent samples t-test and the Chi-square test were used to explore the appropriate relation of variables. Results: A total of 322 patients were included. Their mean age was 74.4 years and 55.6% were male. According to findings, only 74 patients (22.98%) were transferred to the hospital via Emergency Medical Service (EMS), most of them (64.86%) arrived at the right time. There is a significant relationship between EMS transfer use and arriving at the hospital at the right time. Overall, 13.9% of patients received IV rtPA, and 75.5% of the patients received rtPA in less than 60 minutes. Among the patients arrived in the golden time, the average times to treatment were as follows: onset-to-door (OTD), 105 min; door-to-admission, 3 min; admission-to-doctor, 7 min; doctor-to-Computed Tomography (CT), 15 min; CT-to-treatment, 26 min; symptom to needle time, 152 min; and door-to-needle time (DNT), 49 min. Conclusion: According to this study, although the two-third of eligible patients were transferred to the hospital at the right time, the rate of using EMS for patient transportation is low.

Abstract
The application of local hyperthermia, particularly in conjunction with other treatment strategies (like chemotherapy and radiotherapy) has been known to be a useful means of enhancing tumor treatment outcomes. However, to our knowledge, there has been no mathematical model designed to capture the impact of the combination of hyperthermia and chemotherapies on tumor growth and control. In this study, we propose a nonlinear Partial Differential Equation (PDE) model which describes the tumor response to chemotherapy, and use the model to study the effects of hyperthermia on the response of prototypical tumor to the generic chemotherapeutic agent. Ultrasound energy is delivered to the tumor through High Intensity Focused Ultrasound (HIFU), as a noninvasive technique to elevate the tumor temperature in a controlled manner. The proposed tumor growth model is coupled with the nonlinear density dependent Westervelt and Penne's bio-heat equations, used to calculate the net delivered energy and temperature of the tumor and its surrounding normal tissue. The tumor is assumed to be composed of two species: drug-sensitive and drug-resistant. The central assumption underlying our model is that the drug-resistant species is converted to a drug-sensitive type when the tumor temperature is elevated above a certain threshold temperature. The "in silico" results obtained, confirm that hyperthermia can result in less aggressive tumor development and emphasize the importance of designing an optimized thermal dose strategy. Furthermore, our results suggest that increasing the length of the on/off cycle of the transducer is an efficient approach to treatment scheduling in the sense of optimizing tumor eradication.

Abstract
BACKGROUND AA is an acquired dermatosis distributed universally, with multifactorial etiology. It affects the hair follicle with or without nail involvement, resulting in an acute nonscarring alopecia with a relapsing course.1 Being a relatively common skin disease, LPP (lichen planopilaris) is initiated by a chronic lymphocytic inflammation that selectively destructs the hair follicles and eventually leads to scarring alopecia. Also, even though there is enough literature available for the co-existence of AA and LPP with each other and their association with other autoimmune conditions, there are only very few reports on the anatomical concomitance of both disorders.3 AIMS: Although the incidence of not only one but two autoimmune diseases in an immunosuppressed individual is very unusual, we hereby report a case of co-localization of AA and LPP in a patient receiving immunosuppression due to a previous history of SLE (Systemic lupus erythematosus). PATIENTS A 37-year-old woman, housewife, presented to our office with general alopecia on the scalp since about two years ago (Figure 1), particularly on the vertex which was accompanied by mild itching and trichodynia. She had a history of hypothyroidism and lupus erythematosus arthritis. She had been receiving long-term treatment with prednisolone, hydroxychloroquine, azathioprine, and levothyroxine but had not been treated for hair loss. Despite being on all of the above-mentioned immunosuppressants, the patient developed AA and LPP which are both immune-mediated diseases. RESULTS In addition to continuing her oral immunosuppressants, the patient was treated with Minoxidil 5% and Clobetasol solution as well as a higher dose of Azathioprine than she was receiving beforehand. Approximately, 3 months into the treatment, the follicular hyperkeratosis and scalp erythema resolved. Also, hair growth could be seen on AA spots. CONCLUSION Our case report is indicating the possibly mutual immunopathogenesis of these two T cell-mediated disorders. Furthermore, we want to bring attention to the probability of new autoimmune diseases occurring even during treatment with immunosuppressive medications.

Abstract
Following skin injury, the overproduction of reactive oxygen species (ROS) during the inflammatory phase can cause tissue damage and delay in wound healing. Methylene blue (MB) decreases mitochondrial ROS production and has antioxidant effects. The authors aimed to prepare MB-loaded niosomes using the ultra-sonication technique as a green formulation method. A Box-Behnken design was selected to optimize formulation variables. The emulsifier to cholesterol ratio, HLB of mixed surfactants (Span 60 and Tween 60), and sonication time were selected as independent variables. Vesicle size, zeta potential (ZP), and drug entrapment capacity percentage were studied as dependent variables. The optimized formulation of niosomes showed spherical shape with optimum vesicle size of 147.8 nm, ZP of - 18.0 and entrapment efficiency of 63.27%. FTIR study showed no observable interaction between MB and other ingredients. In vivo efficacy of optimized formulation was evaluated using an excision wound model in male Wistar rat. Superoxide dismutase (SOD, an endogenous antioxidant) and malondialdehyde (MDA, an end product of lipid peroxidation) levels in skin tissue samples were evaluated. After 3 days, MDA was significantly decreased in niosomal gel-treated group, whereas SOD level was increased. Histological results indicate rats that received niosomal MB were treated effectively faster than other ones. Graphical abstract.

Abstract
One of a number of critical roles played by NO· as a chemical weapon (generated by the immune system) is to neutralize pathogens. However, the virulence of pathogens depends on the production activity of reductants to detoxify NO·. Broad reactivity of NO· makes it complicated to predict the fate of NO· inside bacteria and its effects on the treatment of any infection. Here, we present a mathematical model of biofilm response to NO·, as a stressor. The model is comprised of a PDE system of highly nonlinear reaction-diffusion equations that we study in computer simulations to determine the positive and negative effects of key parameters on bacterial defenses against NO·. From the reported results, we conjecture that the oscillatory behavior of NO· under a microaerobic regime is a temporal phenomenon and does not give rise to a spatial pattern. It is also shown computationally that decreasing the initial size of the biofilm colony negatively impacts the functionality of reducing agents that deactivate NO·. Whereas nutrient deprivation results in the development of biofilms with heterogeneous structure, its effect on the activity of NO· reductants depends on the oxygen availability, biofilm size, and the amount of NO·.

Abstract
This study evaluates serum copper and magnesium and total antioxidant capacity levels in PCOS patients. In this regard, the probable association of copper and magnesium with total antioxidant capacity (TAC) was investigated. In total, 150 women (60 PCOS patients and 90 healthy subjects) participated in this case-control study. PCOS was diagnosed according to the Rotterdam criteria (2003). Serum Cu, Mg, Ca, TAC, insulin levels, and insulin resistance indices were determined. Insulin was measured using ELISA methods. Serum Cu and Mg levels were measured by an atomic absorption spectrophotometer and the Xylidyl Blue method respectively. The correlations between the parameters were analyzed using the Spearman correlation test. Serum Cu level was significantly higher while TAC was significantly lower in the PCOS patients than those in the controls (p = 0.019 and p = 0.002 respectively). No significant difference was detected between the two groups in terms of serum Mg and Ca levels and Ca/Mg ratio. In insulin-resistant PCOS subjects, there was a negative correlation between Mg levels and homeostatic model assessment for insulin resistance (r = - 0.449, p = 0.006) but a positive correlation between Mg levels and quantitative insulin sensitivity check index (r = 0.480, p = 0.003). A negative correlation also existed between Mg levels and TAC in non-insulin-resistant PCOS patients (r = - 0.407, p = 0.04).
