    Abstract Background: Primary Systemic Sclerosis (PSS) is a connective tissue disorder characterized by excessive collagen deposition in the skin and internal organs. Interstitial lung disease (ILD) is a late demonstration of PSS and cytokines can contribute to the disease pathology. The purpose of the current study was to determine the association between serum interleukin-6 level and pulmonary involvement in progressive systemic sclerosis.
    Methods and materials: Demographic data and serum interleukin-6 levels were measured for 30 PSS patients with pulmonary involvement (case group) and 30 PSS patients without pulmonary involvement (control group) following informed consent. The disease duration and activity, C-reactive protein (CRP), chest x-ray and highresolution CT scan (HRCT) findings, ejection fraction (EF) and echocardiography findings, and pulmonary artery pressure (PAP) were also determined in both groups.
    Results: The age of patients in case and control groups was 52.5 ± 9.3 and 43.9 ± 9.7 years, respectively (p = 0.001). No significant difference was found between serum levels of IL-6 in case and control groups (73.1 ± 95.4 vs 46.7 ± 83.6 pg/ml, p = 0.267). However, IL-6 level was significantly higher in male case patients compared to male controls (p = 0.007). The duration of PSS was 11.6 ± 6.4 and 7.4 ± 4.2 years in case and control groups, respectively (p = 0.002). The quantitative CRP and PAP was also significantly higher in case patients (p = 0.01 and p < 0.001, respectively). There was found reticulonodular pattern in 20 (66.7%) of the cases, whereas 28 (93.3%) of the controls had normal Chest X-rays (CXR) (p < 0.001). EF was significantly lower in case patients compared to control patients (p = 0.001).
    Conclusion: The serum level of IL-6 did not appear to have a relationship with pulmonary involvement, hence it could not be regarded as a potential therapeutic target.

    Abstract Exercise has been shown to be associated with reduced risk and improving outcomes of several types of cancers. Irisin -a novel exercise-related myokine- has been proposed to exert beneficial effects in metabolic disorders including cancer. No previous studies have investigated whether irisin may regulate malignant characteristics of ovarian cancer cell lines. In the present study, we aimed to explore the effect of irisin on viability and proliferation of ovarian cancer cells which was examined by MTT assay. Then, we evaluated the migratory and invasive abilities of the cells via transwell assays. Moreover, the percentage of apoptosis induction was determined by flow cytometry. Furthermore, the mRNA expression level of genes related to the aerobic respiration (HIF-1α, c-Myc, LDHA, PDK1 and VEGF) was detected by real-time PCR. Our data revealed that irisin treatment significantly attenuated the proliferation, migration and invasion of ovarian cancer cells. Additionally, irisin induced apoptosis in ovarian cancer cells. We also observed that irisin regulated the expression of genes involved in aerobic respiration of ovarian cancer cells. Our results indicated that irisin may play a crucial role in inhibition of cell growth and malignant characteristics of ovarian cancer. These findings may open up avenues for future studies to identify the further therapeutic use of irisin in ovarian cancer management.

    Abstract Background: Neuropathic pain results from lesions or diseases affecting the somatosensory system. The management of a patient with chronic neuropathic pain remains a challenge several studies report the analgesic effect of serotonin receptor antagonists in different models of experimental pain. The present study was designed to study the effect of systemic administration of risperidone, on behavioral scores of neuropathic pains in chronic constriction (CCI) model in rats.
    Methods: Inducing neuropathic pain with the CCI model which causes heat hyperalgesia, heat, and mechanical allodynia was performed on rats, and then, in two phases, risperidone effect was determined. In the acute phase, risperidone 1, 2, 4 mg was administered for three groups half an hour before behavioral tests on the 7th, 14th, and 21st day after surgery, and in the chronic phase, risperidone 1, 2, and 4 mg was administered for three different groups from the 1st to 14th days after surgery than on 14th-day behavioral scores were performed. For gene expression analysis, samples are taken from spinal cord tissues in lumbar segments.
    Results: This study shows chronic administration of risperidone as an antipsychotic drug was effective on heat hyperalgesia and allodynia. However, only the max dosage (4 mg) of risperidone showed meaningful improvement in increasing mechanical allodynia. However, acute administering of risperidone did not show any meaningful changes in behavioral tests on neuropathic pain induced by chronic constriction injury of the sciatic nerve in rats. In addition, gene expression results showed an increase in IL-4 and IL-10 gene expression in the risperidone group compared to the sham group.
    Conclusion: This study suggests the helpful preventive effects of risperidone in developing and increasing neuropathic pain, but it does not have any instant effect.

    Abstract The outbreak of coronavirus disease 2019 (COVID-19), which was originated from a severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) infection, has become an international public health emergency. The aim of this study was to assess the clinical symptoms and physical findings in both hypertensive and nonhypertensive patients infected with COVID-19.
    Methods: A retrospective observational case-control study with diagnosis of COVID-19 by laboratory-confirmed test was conducted on 280 consecutive unselected patients. This was a single-center study. The demographics, laboratory, and clinical findings data were extracted from the hospital registry database.
    Results: Of our 280 patients in the study, there were 149 men (53%) and 138 (50%) were older than 60 years (mean=67.75), and also 50 in-hospital deaths occurred (mortality rate, 17%). Total 19(6.9%) were taking opioid, and smoking. There were no significant differences in the rate of fever, cough, sputum production, gastrointestinal symptoms, myalgia, and headache in the both hypertensive and nonhypertensive groups. The prevalence of underlying diseases was significantly higher in older patients in comparison with younger ones (
    Conclusion: Hypertension is associated with a poor prognosis and higher mortality among COVID-19 patients. Optimizing blood pressure is essential during the management of COVID-19. Our research implies the importance of early care and education of old patient with hypertension and other comorbidities.

    Abstract The coronavirus-related severe acute respiratory syndrome (SARS-CoV) in 2002/2003, the Middle East respiratory syndrome (MERS-CoV) in 2012/2013, and especially the current 2019/2021 severe acute respiratory syndrome-2 (SARS-CoV-2) negatively affected the national health systems worldwide. Different SARS-CoV-2 variants, including Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1), Delta (B.1.617.2), and recently Omicron (B.1.1.529), have emerged resulting from the high rate of genetic recombination and S1-RBD/S2 mutation/deletion in the spike protein that has an impact on the virus activity. Furthermore, genetic variability in certain genes involved in the immune system might impact the level of SARS-CoV-2 recognition and immune response against the virus among different populations. Understanding the molecular mechanism and function of SARS-CoV-2 variants and their different epidemiological outcomes is a key step for effective COVID-19 treatment strategies, including antiviral drug development and vaccine designs, which can immunize people with genetic variabilities against various strains of SARS-CoV-2. In this review, we center our focus on the recent and up-to-date knowledge on SARS-CoV-2 (Alpha to Omicron) origin and evolution, structure, genetic diversity, route of transmission, pathogenesis, new diagnostic, and treatment strategies, as well as the psychological and economic impact of COVID-19 pandemic on individuals and their lives around the world.

    Abstract Abstract Background The selection of non-apoptotic sperm is related to successful fertilization. This study investigated the protective effects of melatonin and the role of the MACS (magnetically activated cell sorting) method to prevent oxidative damage in vitro and improve sperm quality parameters such as viability and DNA integrity. Materials and methods Semen analysis was performed on 20 different eligible donors participating in the study. Sperm viability and concentration were checked at time of 0 (0 h). In order to conduct more studies after 24 h (24 h), the remaining sperm suspension was divided into a control group and six experimental groups. DNA fragmentation was assessed using the TUNEL assay. Results The treatment of human spermatozoa with 100 µM hydrogen peroxide for 24 h induced a significant increase in phosphatidylserine externalization and significantly increases apoptotic sperm (p ≤ 0.001). TUNEL analysis of human sperm pretreated with 100 µM hydrogen peroxide for 24 h showed that the percentage of sperm with fragmented DNA was significantly reduced after sorting by MACS (P ≤ 0.001). However, pretreated human sperm with 1 μM melatonin for 24 h could effectively maintain sperm motility and progressive motility. Conclusions Pretreated human spermatozoa with 1 µM melatonin for 24 h could be effective for maintenance of sperm motility and progressive motility. Although 100 µM hydrogen peroxide-treated sperm were used, MACS was used to retain the appropriate sperm and select high-quality sperm.

    Abstract Background: Universally, asthma has high prevalence rates and this has led numerous studies done into its causes. Despite extensive study on asthma the association between 25-Hydroxy Vitamin D (25(OH) vit. D) and asthma remains uncertain. In this study, the associations of 25(OH) vit. D levels with asthma and with the severity of asthma were evaluated.
    Methods: This was a case-control study performed in 2015 in the city of Isfahan. In this study 520 children were studied. Children with asthma were classified as cases and children who were referred for reasons other than respiratory problems and asthma were considered as controls. Serum 25 (OH) vit. D levels were then examined and compared between the two groups. Differences among groups were stated to be statistically significant when
    Results: There were 260 asthmatic children and 260 controls in the present study. The mean 25 (OH) vit. D levels in the case group was 25.5 ± 16.62 and  16.76 ± 31.40 the control group and this difference was statistically significant (P < 0.05). 25(OH) vit. D levels were found to be 28.05 ± 16.98 in non-severe asthma and 21.41 ± 15.20 in severe asthma. Consequently 25(OH) vit. D level had inverse relationship with asthma severity (P = 0.002).
    Conclusions: As the results of this study showed, the lower level of 25(OH) vit. D correlated with the higher severity of asthma manifestations. Therefore, it is recommended that 25(OH) vit. D levels get routinely checked especially in severe asthma cases and if the deficiency presents, appropriate therapeutic measures be used to reduce the asthma severity.

    Abstract Microbial infection and cancer are two leading causes of global mortality. Discovering and developing new therapeutics with better specificity having minimal side-effects and no drug resistance are of an immense need. In this regard, cationic antimicrobial peptides (AMP) with dual antimicrobial and anticancer activities are the ultimate choice. For better efficacy and improved stability, the AMPs available for treatment still required to be modified. There are several strategies in which AMPs can be enhanced through, for instance, nano-carrier application with high selectivity and specificity enables researchers to estimate the rate of drug delivery to a particular tissue. In this review we present the biology and modes of action of AMPs for both anticancer and antimicrobial activities as well as some modification strategies to improve the efficacy and selectivity of these AMPs.

    Abstract Introduction: Today, colon cancer is one of the most common types of gastrointestinal cancer worldwide. CD133 as a known cancer stem cell marker has been found effective in cell proliferation and differentiation in various cancers, including colon cancer. We aimed to investigate the relationship between CD133 expression in colon cancer with prognostic factors and survival rate of patients with colon cancer by immunohistochemistry.
    Methods: Formalin-fixed paraffin-embedded (FFPE) tissue was taken from patients with colon cancer. Histopathology examination was done using hematoxylin and eosin staining. Immunohistochemistry was performed to determine CD133 expression. Association between CD133 expression and clinicopathological profile was then assessed.
    Results: There was a statistically significant association between CD133 protein expression and sex , cancer stage, and lymphatic invasion (p = 0.044, p = 0.131, and p = 0.002, respectively). However, no significant correlation was identified between CD133 expression and other factors, including age of patients with colorectal cancer (CRC) (p = 0.267), tumor location (p = 0.494), tumor differentiation grade (p = 0.263), neural tissue invasion, and 5-year survival (p = 0.054).
    Conclusion: CD133 is a useful predictive or prognostic biomarker for CRC in clinical assessment and may serve as a potential therapeutic target for CRC.
