Main Polymorphisms in Aspirin-Exacerbated Respiratory Disease. Gene 2023; 870:147326. [PMID: 37011853 DOI: 10.1016/j.gene.2023.147326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 02/22/2023] [Accepted: 02/27/2023] [Indexed: 04/04/2023]
Abstract
Aspirin exacerbated respiratory disease (AERD) is a condition caused by increased bronchoconstriction in people with asthma after taking aspirin or another NSAID. Molecular analysis of the human genome has opened up new perspectives on human polymorphisms and disease. This study was conducted to identify the genetic factors that influence this disease due to its unknown genetic factors. We evaluated research studies, letters, comments, editorials, eBooks, and reviews. PubMed/MEDLINE, Web of Sciences, Cochrane Library, and Scopus were searched for information. We used the keywords polymorphisms, aspirin-exacerbated respiratory disease, asthma, allergy as search terms. This study included 38 studies. AERD complications were associated with polymorphisms in ALOX15, EP2, ADRB2, SLC6A12, CCR3, CRTH2, CysLTs, DPCR1, DPP10, FPR2, HSP70, IL8, IL1B, IL5RA, IL-13, IL17RA, ILVBL, TBXA2R, TLR3, HLA-DRB and HLA-DQ, HLA-DR7, HLA-DP. AERD was associated with heterogeneity in gene polymorphisms, making it difficult to pinpoint specific gene changes. Therefore, diagnosing and treating AERD may be facilitated by examining common variants involving the disease.

Abstract
BACKGROUND Millions of people are diagnosed with cancer each year, and fighting it puts a heavy financial burden on communities and governments. Numerous advances have been made in the field of cancer; one of the newest methods is using oncolytic viruses. This study aimed to evaluate the effect of oncolytic Newcastle disease virus wild-type strains (NDV-WTS) on the immune system. MATERIAL AND METHODS Forty mice were divided into four groups (10 animals in each group). The control group received phosphate buffered saline, and experimental group 1 (NDV-WTS 1), experimental group 2 (NDV-WTS 2), and experimental group 3 (NDV-WTS 3) received 10-1, 10-2, and 10-3 titers of Newcastle virus on 0, 14th, and 28th days. On the 31st day, 100 µL of Newcastle virus was injected into the left footpads of animals. After 48 hours, delayed-type hypersensitivity (DTH) reactions were measured. On the 33rd day, peritoneal macrophages were isolated. Then proliferation of the cells was measured by the methyl-thiazolyl-tetrazolium (MTT) test. Neutral red uptake and respiratory burst of peritoneal macrophages were also assessed. Data were analyzed using statistical software SPSS, version 19. RESULTS The results of the DTH test showed that footpad swelling in control, NDV-WTS 1, NDV-WTS 2, and NDV-WTS 3 groups were 23.5%, 23.5%, 23.6% and 23.6%. No significant differences were seen between the groups in this regard (P > 0.05). A negative nitroblue tetrazolium (NBT) reduction test as an indicator of macrophage's respiratory burst, showed no significant difference between the groups (P > 0.05). The neutral red uptake assay and MTT test showed no significant differences between the groups (P > 0.05). CONCLUSION The results of this study showed that NDV-WTS in doses of 10-1, 10-2, and 10-3 have no adverse effects on healthy normal cells.

Comparative Study of Clinical Characteristics of COVID-19 Patients with or without Digestive Symptoms in Razi Hospital, Ahvaz, Khuzestan. Endocr Metab Immune Disord Drug Targets 2022; 23:647-671. [DOI: 10.2174/1871530322666220823155956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 05/29/2022] [Accepted: 06/03/2022] [Indexed: 11/22/2022]
Abstract
Aims:
The pandemic of coronavirus disease 2019 (COVID-19), has emerged as a dire health problem, causing a massive crisis for global health.
Background:
Most commonly reported clinical manifestations are fever, fatigue and dry cough. Interestingly, a small percentage of patients experience GI symptoms with the most common being anorexia, diarrhea, nausea and vomiting. We aimed to investigate a comparable study of COVID-19 patients with or without gastrointestinal patients (GI).
Methods:
Collective data of clinical manifestations and laboratory reports of patients admitted in Razi Hospital, Ahvaz, Khuzestan, Iran, during two weeks were analyzed.
Results:
Our results showed that GI symptoms are not statistically significant criteria to be predictive or prognostic factors in the COVID-19 patients despite they are probably related to acute or non-acute phase of the disease. Moreover, non-specific GI symptoms seem to be as a result of cytokine storm occurred during the disease.
Conclusion:
Therefore, our results did not support GI tract involvement as a common route of COVID-19 infection. Maybe future research will shed light on why and how the gastrointestinal system became infected by COVID-19.

Platelet Count and IgE Level in Chronic Idiopathic Urticaria: A Case-control Study. RECENT ADVANCES IN INFLAMMATION & ALLERGY DRUG DISCOVERY 2022; 16:44-49. [PMID: 35289259 DOI: 10.2174/2772270816666220314154951] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 12/31/2021] [Accepted: 01/11/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND AIM Chronic Urticaria is an allergic disorder that affects about 0.5 to 5% of the population in different communities. The disease's chronic course and long-term onset impose high economic and psychological costs on communities, adversely affecting individual and social life. Platelets play a role in various pathophysiological processes, including inflammation and immunology. Growing evidence suggests that platelets are actively involved in the pathogenesis of various inflammatory disorders, including inflammatory skin diseases. This study investigated the relationship between platelet and immunoglobulin-E markers and chronic idiopathic urticaria. MATERIALS AND METHODS In the present case-control study, for the study population, patients with chronic idiopathic urticaria were referred to the Asthma and Allergy Clinic, and their caregivers were selected as the case and control groups, respectively. In this study, the mean platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), and Total IgE values were simultaneously measured in the case and control groups. After taking 5CCs of venous blood, a blood sample was sent to the laboratory for platelet and IgE marker measurements. RESULTS 100 patients and 100 healthy persons were evaluated in this study. The mean age in the case group was 34.95, and in the control group was 35.78 years. The results showed that the mean values of PLT, MPV, PDW, and Total IgE in the case group were 12.86, 9.83, 252190, and 147.05, respectively. The mean values of PLT, MPV, PDW, and Total IgE in the control group were 16.93, 7.53, 231410, and 15.29, respectively, which was statistically significant (P = 0.001). Moreover, total IgE in the Autologous Serum Skin Test (ASST) positive group was higher than ASST negative group and was statistically significant (P = 0.001). CONCLUSION The study results indicate the possible role of platelets in urticaria and inflammation. MPV in patients with chronic urticaria was higher than in the control group. The present study showed no significant relationship between the severity of urticaria and platelet markers, but there was a significant relationship between the severity of urticaria and ASST. Moreover, the severity of urticaria was higher in the positive skin test group.

Abstract
The global rate of cancer has increased in recent years, and cancer is still a threat to human health. Recent developments in cancer treatment have yielded the understanding that viruses have a high potential in cancer treatment. Using oncolytic viruses (OVs) is a promising approach in the treatment of malignant tumors. OVs can achieve their targeted treatment effects through selective cell death and induction of specific antitumor immunity. Targeting tumors and the mechanism for killing cancer cells are among the critical roles of OVs. Therefore, evaluating OVs and understanding their precise mechanisms of action can be beneficial in cancer therapy. This review study aimed to evaluate OVs and the mechanisms of their effects on cancer cells.

Abstract
OBJECTIVE Rubella is a highly contagious viral disease with a significant teratogenic effect. Various results have been published about the seroprevalence of rubella in Iran. A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-systematic review and meta-analysis were conducted to assess the immunity against rubella in Iranian women. METHODS Eleven English and Persian electronic databases including PubMed, ScienceDirect, Scopus, Web of Science, Google Scholar, Embase, Scientific Information Database, Iran doc, Iran Medex, Magiran, and Medlib were searched using the keywords: Epidemiology, Prevalence, Rubella, Women, Childbearing age, Reproductive age, and Iran. A mathematician (NS) reviewed all steps for accuracy. RESULTS Out of 1,520 articles, 25 well-conducted studies with a total amount of 10,145 women were reviewed. The pooled prevalence rate of anti-rubella IgG was 84% (95% CI: 83%-86%). The highest prevalence rate of IgG was in Zahedan, Rasht, and Arak (each 100%), while the lowest prevalence was in Jahrom (54%). Subgroup analysis showed that from 1989 through 2012, the IgG prevalence rate increased from 78% (95% CI: 73-83%) to 99% (95% CI: 98 100%). CONCLUSIONS Although the vaccination program seems working in Iran, some peripheral regions may be a target to improve health care policies.

Abstract
BACKGROUND Asthma is an important reason for hospitalization in children aged under five years. Information about the current status of asthma in Iranian children can help the Iranian health sector plan carefully and prevent asthma incidence by educating the families. The present systematic review and meta-analysis is aimed at estimating asthma prevalence in Iranian children and adolescents. METHOD Data were found using keywords such as prevalence, epidemiology, asthma, adolescent, children, pediatrics, Iran in Web of Science, Scopus, PubMed, Cochrane, and Embase databases. Three national databases, including Magiran, Barakat Pharmed Co (Iran medex), and Scientific Information Databank (SID) were searched until 1 October 2020. Cross-sectional and original studies were included in the study, and then, quality assessment was done using the National Institutes of Health's Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. A pooled estimated prevalence of asthma was calculated using Der Simonian-Laird random model. Egger's test was used to evaluate publication bias. The data were analyzed using the STATA software version 16. RESULTS 30 studies were selected and investigated. The prevalence of asthma in children and adolescents was 6% and 8%, and the prevalence in boys and girls was 9% and 8%, respectively. Among the asthma symptoms, wheezing had the most prevalence (17% in children and 19% in adolescents) and sleep disturbance had the lowest prevalence (6% in children and 6% in adolescents). CONCLUSION The prevalence of asthma in Iranian children and adolescents is lower than in the world. Existing strategies should be pursued followed. Also, guidelines for asthma control and prevention should be considered in the future.

Abstract
Controversy regarding the effects of betaine supplementation on cardiovascular markers has persisted for decades. This systematic review and meta-analysis compared the effects of betaine supplementation on cardiovascular disease (CVD) markers. Studies examining betaine supplementation on CVD markers published up to February 2021 were identified through PubMed, the Cochrane Library, Web of Science, Embase, and SCOPUS. Betaine supplementation had a significant effect on concentrations of betaine (MD: 82.14 μmol/L, 95% CI: 67.09 to 97.20), total cholesterol (TC) (MD: 14.12 mg/dl, 95% CI%: 9.23 to 19.02), low-density lipoprotein (LDL) (MD: 10.26 mg/dl, 95% CI: 6.14 to 14.38)], homocysteine (WMD: -1.30 micromol/L, 95% CI: -1.61 to -0.98), dimethylglycine (DMG) (MD: 21.33 micromol/L, 95% CI: 13.87 to 28.80), and methionine (MD: 2.06 micromol/L, 95% CI: 0.23 to 3.88). Moreover, our analysis indicated that betaine supplementation did not affect serum concentrations of triglyceride (TG), high-density lipoprotein (HDL), fasting blood glucose (FBG), C-reactive protein (CRP), liver enzymes [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT)], and blood pressure. Our subgroup analysis suggested that a maximum dose of 4 g/d might have homocysteine-lowering effects without any adverse effect on lipid profiles reported with doses of ≥4 g/d. In conclusion, the present systematic review and meta-analysis supports the advantage of a lower dose of betaine supplementation (<4 g/d) on homocysteine concentrations without the lipid-augmenting effect observed with a higher dosage.

Abstract
We evaluated the effects of ketogenic diets (KDs) on body mass (BM), fat mass (FM), fat-free mass (FFM), body mass index (BMI), and body fat percentage (BFP) compared to non-KDs in individuals performing resistance training (RT). Online electronic databases including PubMed, the Cochrane Library, Web of Science, Embase, SCOPUS, and Ovid were searched to identify initial studies until February 2021. Data were pooled using both fixed and random-effects methods and were expressed as weighted mean difference (WMD) and 95% confidence intervals (CI). Out of 1372 studies, 13 randomized controlled trials (RCTs) that enrolled 244 volunteers were included. The pooled results demonstrated that KDs significantly decreased BM [(WMD = -3.67 kg; 95% CI: -4.44, -2.90, p < 0.001)], FM [(WMD = -2.21 kg; 95% CI: -3.09, -1.34, p < 0.001)], FFM [(WMD = -1.26 kg; 95% CI: -1.82, -0.70, p < 0.001)], BMI [(WMD = -1.37 kg.m-2; 95% CI: -2.14, -0.59, p = 0.022)], and BFP [(WMD = -2.27%; 95% CI: -3.63, -0.90, p = 0.001)] compared to non-KDs. We observed beneficial effects of KDs compared to non-KDs on BM and body fat (both FM and BFP) in individuals performing RT. However, adherence to KDs may have a negative effect on FFM, which is not ameliorated by the addition of RT.

Abstract
Context: Research has shown the modulations of Follistatin (FST) and Myostatin (MST) following weight loss.Objective: We evaluated the effects of gradual weight loss (GWL) and rapid weight loss (RWL) on serum MST, FST, and body composition in overweight and obese females.Materials and methods: Thirty-six overweight and obese females successfully completed the study interventions: GWL (n = 18) or RWL (n = 18). Serum MST and FST concentrations, as well as anthropometric measurements, were collected at baseline and at the conclusion of each weight loss intervention.Results: MST concentration significantly (p < .05) decreased in the GWL; while FST concentration, body fat percentage and skeletal muscle mass significantly declined in both conditions. The loss in skeletal muscle mass was significantly greater in RWL relative to GWL.Discussion and conclusion: GWL was more effective than RWL in preserving skeletal muscle mass in overweight and obese females. Moreover, GWL leads to declines in MST concentrations.

Abstract
BACKGROUND The extensive impacts of vitamin D on the immune system has gathered the attention of scholars in last years. In this regard, studies about vitamin D and incidence of asthma have showed various results. The aim of this study was to evaluate the effect of vitamin D supplements on clinical outcomes in asthmatic children with vitamin D insufficiency. MATERIALS & METHODS This before-after interventional study was conducted on all asthmatic children who attended the Be'sat Hospital, Iran. Serum levels of 25(OH)D, asthma severity and pulmonary function tests before and after therapeutic prescription of vitamin D were evaluated. Serum levels of 25(OH)D were measured by enzyme-linked immunosorbent assay. RESULTS The mean age of the samples was 10.69±9.78 years and 39 subjects (57.4%) were male. The primary mean level of serum 25(OH)D (18.21±8.22, ng/mL) has significantly (p<0.05) increased after treatment (35.45±9.35, ng/mL). Also, asthma severity, forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC indicators were significantly (p<0.05) increased after treatment. CONCLUSION We can conclude that therapeutic prescription of vitamin D is very effective in improving the clinical status of asthmatic children.

Abstract
BACKGROUND CYP2C19 a metabolizing enzyme and Heat Shock Proteins (HSP) are induced in stress conditions, such as hypoxia and ischemia. Recently, polymorphism in the CYP2C19 and HSP genes has been established in Aspirin-Exacerbated Respiratory Disease (AERD). OBJECTIVE We investigated the polymorphism of these two genes in Kurdish patients with AERD. METHODS This study involved 306 subjects, referred to the Be'sat hospital in Kurdistan Province, which were divided into three groups, (i) Aspirin Induced Asthma (AIA), (ii) Aspirin Tolerant Asthma (ATA), and (iii) healthy subjects as control. The subjects as control and ATA\AIA groups were verified by the physician. The demographic data of each subject with respect to age, sex, parental education, and residence was collected. Spirometry was performed on subjects and blood samples were collected for serum Immunoglobulin E (IgE) estimation and molecular tests. Genotyping was done for CYP2C19 681G>A، CYP2C19 636G>A, and HSPA1B1267A>G by using PCR- Restriction Fragment Length Polymorphism (RFLP) and for HSPA1B-179C>T by High Resolution Melting (HRM). RESULTS Demographic statistics were not significantly different between the three groups (p>0.05). Further, genotypes were also not observed to be significantly different in the genes of CYP2C19 681G>A, CYP2C19 636G>A and HSPA1B1267A>G (p>0.05). However, the heterozygote genotype in HSPA1B-179 C>T in AIA group was higher than the control group (p<0.05). Notably, 92.8 % of the subjects showed heterozygote genotype in HSPA1B1267 A>G. In clinical tests, FEV-1, FVC, and asthma severity in the AIA group were higher than control and additionally IgE levels were lower in this group (p<0.05). CONCLUSION The results confirm the association of polymorphism in the HSPA1B-179C>T and HSPA1B1267A>G with AERD in the Kurdish population.

Abstract
BACKGROUND Fasciolosis, an infectious disorder with a serious public health burden, is caused by two liver flukes belonging to the genus Fasciola. Iran is among the endemic areas for this disease. This study aimed to determine the seroprevalence of human fasciolosis in Iran. METHODS A systematic search was conducted in Embase, PubMed/MEDLINE, Web of Science (WoS), and Google Scholar, as well as Iranian databases including Scientific Information Database (SID), Magiran and Irandoc from January 2000 to June 2016. In order to determine fasciolosis prevalence, the DerSimonian-Laird random model was used. In order to assess the heterogeneity among studies, I2 and Q tests were used. To investigate the source of heterogeneity, meta-regressions based on the year of publication and sample size were performed. Sensitivity analysis was carried out to ensure the stability of obtained results. RESULTS Eleven relevant studies were included. According to the data analysis a prevalence rate of 2% [95% CI 1-5] was found. No statistically significant relationship between gender and disease prevalence could be detected. We found an OR of developing fasciolosis of 1.67 [95% CI: 0.42 - 6.60] in people who had consumed vegetables versus those who did not eat vegetables, even though this did not yield statistical significance. CONCLUSION The findings of the current study can be valuable and help the health-care workers and policy-makers in programming and implementing ad hoc interventions in order to prevent the incidence of disease.

Abstract
BACKGROUND Diabetes mellitus is one of the most common chronic metabolic diseases in children and adolescents, which changes the cellular metabolism. Phosphorus is an essential element for metabolism. Early in the progression of diabetes, a paradoxical metabolic imbalance in inorganic phosphate (Pi) occurs that may lead to reduced high energy phosphate and tissue hypoxia. While low and high uncontrolled blood sugars can be easily recognized by clinical symptoms, low and high plasma inorganic phosphate remain unrecognizable. Therefore, we aimed to assess the association between hemoglobin A1c (HbA1c) with serum inorganic phosphate in children with type 1 diabetes. MATERIALS AND METHODS This cross-sectional study was conducted on 102 patients selected from a pediatric ward in 17th Shahrivar hospital in Rasht, North of Iran. Clinical data including age, sex, height, weight, BMI, duration of diabetes, the level of HbA1c, and phosphorus were gathered. The level of HbA1c was adjusted by age in the final analysis. RESULTS The mean age of samples was 9.98±3.91 years old and 46 participants (45.1%) were male. It was found that HbA1c had a reversed and significant relationship with BMI (r=-0.215 and P=0.03), but there was no correlation between phosphate, age, height and weight, duration of diabetes mellitus, or rate of insulin consumption with HbA1c (P>0.05). CONCLUSION The finding showed that HbA1c had a reversed relationship with BMI but there was no correlation between phosphate and HbA1c.

Abstract
Aim: Stem cell factor (SCF) may be associated with inflammatory processes leading to aspirin-induced asthma. This study evaluated the relationship between serum level of SCF and its soluble receptor with aspirin-induced asthma. Methods & materials: Twenty-five patients and 25 healthy controls were enrolled in this study. The concentration of SCF and mast/stem cell growth factor receptor (C-kit) was determined in serum samples. Spirometry and rhinometry were performed to determine the severity of the disease. p < 0.05 were considered significant. Results: The serum levels of SCF and C-kit receptor were significantly higher in the case group. The serum SCF and C-kit level had a significant positive correlation with the severity of asthma, disease duration and nasal obstruction. Conclusion: Our findings suggest that SCF and C-kit receptors have a direct effect on the severity of aspirin-induced asthma.

Abstract
The harmful dose-dependent side effects of chemotherapy drugs have caused the discovery of novel perspective to evaluate chemotherapy protocols. In this study, the potential application of Compritol was investigated as a major scaffold into nanostructured lipid careers to highlight myricetin efficiency in treatment of breast cancer cells along with codelivery of docetaxel (DXT). Characterization of myricetin-loaded NLCs was carried out by measuring the particle size and zeta potential, using the scanning electron microscopy. MTT, DAPI staining, flow cytometric, and RT-PCR (real-time) assays were used to recognize novel formulation behavior on cell cytotoxicity as well as recognizing molecular mechanism of formulation concerning apoptosis phenomenon. Myricetin-loaded NLCs reduced the cell viability from 50 ± 2.3 to 40 ± 1.3% (p < 0.05). Percentage of apoptosis improved with combination treatment of myricetin-loaded NLCs and DXT in the MDA-MBA231 breast cancer cells. Expression of antiapoptotic genes (survivin, Cyclin B1, and Mcl1) indicated a significant reduction in factor along with increment in proapoptotic factor Bax and Bid mRNA rates. Overall, our results represented that the NLC delivery system could be a promising strategy to enhance the effect of anticancer agents such as DXT on breast cancer.

Aligned Expression of IFI16 and STING Genes in RRMS Patients' Blood. Endocr Metab Immune Disord Drug Targets 2019; 20:878-886. [PMID: 31362682 DOI: 10.2174/1871530319666190729112246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Revised: 06/23/2019] [Accepted: 06/25/2019] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Multiple sclerosis (MS) is a chronic neurodegenerative disease of the central nervous system. The most common disease phenotype is Relapsing-Remitting MS (RRMS). Beta interferons are the first line of RRMS patients' treatment. Interferon-inducible protein 16 (IFI16) as a DNA sensing molecule and its downstream complex stimulator of interferon genes (STING) play a critical role in the activation of type I interferons. Hence we aimed to evaluate the expression rate of IFI16 and STING in RRMS patients' blood under a different type of IFNβ treatment. METHODS In the present study, 99 individuals participated. The participants were divided into 4 groups: 28 control subjects, 25 new cases of RRMS patients, 25 RRMS patients treated with IFNβ-1a (B1a), 21 RRMS patients treated with IFNβ-1b (B1b). The EDTA-treated blood samples were taken and transferred at standard conditions to the Cellular and Molecular Research Center of Shahrekord University of Medical Sciences, RNA was extracted and converted into cDNA. To evaluate the expression of IFI16 and STING, the Real-Time PCR method using SYBR Green/ROX qPCR master mix was performed done. The level of genes expression was measured using 2-ΔΔCt method. The obtained data were analyzed using SPSS v22 software. RESULTS Comparison of the IFI and STING mRNA expression in blood samples in association with gender and age showed no significant differences (p>0.05). Also, the evaluation of IFI16 mRNA level revealed that the IFI16 genes' expressions were remarkably higher in the new case group compared to the control group, however, STING expression did not show any significant difference. The mRNA levels of IFI16 and STING in IFNβ-treated groups were significantly lower than the new case group (p<0.001). Also, the genes' expressions in both the IFNβ-treated groups were significantly lower compared to the control group (p<0.001). In the assessment of the correlation of IFI16 and STING expressions with age and sex in different research groups, no statistically significant differences were seen (p>0.05). CONCLUSION Perhaps the IFNβ therapy decreases the IFI16 and STING expression in a STINGdependent pathway as a negative feedback mechanism for regulation of the immune system and suppression of pro-inflammatory cytokines production. The important role of DNA sensing molecules and STING-dependent pathway in MS gives a new insight into future treatment based on STING-direct therapies.

Abstract
Background: The etiology of allergic rhinitis includes an increase in cytokine levels, including IL- 4, IL-13, IL-17, and reduction in B7 homologous 1 (B7-H1) or programmed cell death-1 ligand-1 (PD-L1), a new member of the CD28: B7 stimulant molecule family. The aim of this study was to determine the relationship between cytokines and PD-L1. Methods: In this experimental study, 80 patients with allergic rhinitis were enrolled according to inclusion and exclusion criteria. The severity and stage of the disease were determined by a specialist physician. A 5 cc venous blood sample was collected from the patients. IL-4, IL-17, INFγ and PD-L1 were measured using ELISA technique. Results: There was a significant correlation between SPD-L1 and INFγ, IL-4 and IL-17 in allergic rhinitis patients (P < 0.05). Statistical analysis based on the severity of the disease (Mild, Moderate and Severe) showed a significant positive correlation between the SPD-L1 and INFγ in all three levels (P < 0.001). There was also a significant negative correlation between SPD-L1 and two cytokines IL-4 and IL-17 (P < 0.001). Conclusion: PD-L1 may have a protective role against allergic rhinitis, although the precise mechanism requires further detailed studies.

The Prevalence of Allergic Rhinitis among Iranian Children: A Systematic Review and Meta-Analysis. Endocr Metab Immune Disord Drug Targets 2019; 20:189-197. [PMID: 31113353 DOI: 10.2174/1871530319666190515100735] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 04/15/2019] [Accepted: 04/15/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND The prevalence of allergic rhinitis in the world is 10-15%, and it is currently the most common chronic disease among children. There is no comprehensive statistics about the prevalence of allergic rhinitis among Iranian children, therefore, this systematic review and metaanalysis was conducted to evaluate the prevalence of allergic rhinitis among the Iranian children. METHODS The present study was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. The data was collected using key words including allergic rhinitis, prevalence, epidemiology, child OR children, pediatrics and Iran, in international databases including PubMed, Scopus, Web of Science, Cochrane, Embase, and three national databases including Magiran, Iran Medex, and Scientific Information Databank (SID) till December 2018. The STROBE checklist was used for quality assessment. The data were analyzed using STATA software version 12.1. RESULTS The prevalence of allergic rhinitis in children and adolescents were 18% (99.7% CI: 10-28% with publication bias of 0.174) and 25% (99.8% CI: 17-33 with publication bias of 0.617) respectively. The prevalence of allergic rhinitis in males was estimated to be 27% (99.4% CI: 17-36) with publication bias of 0.538 and in females was 23% (99.4% CI: 14-31) with publication bias of 0.926. CONCLUSION The prevalence of allergic rhinitis is approximately high among Iranian children and adolescents; thus, educational strategies should be considered to decrease the prevalence of this disease in Iran.

Abstract
OBJECTIVES Primary dysmenorrhea is a painful uterine contraction caused by endometrial laceration. Drug therapies and complementary medicine have been used to treat dysmenorrhea. The aim of this study was to investigate and offer an updated perspective on the treatments for dysmenorrhea. METHODS The present study was conducted in accordance with the PRISMA checklist for systematic reviews and meta-analyses. The required information was collected based on searches for the following keywords: treatment, primary dysmenorrhea, medicinal plants, chemical drugs, and herbs. Searches were performed on databases Pubmed, Web of Sciences, Scopus, Iran medex, and SID by March 2018 to find literature in the English and Persian languages on this subject without a time limit. RESULTS This review included 17 papers, 10 of which on complementary medicine, three on drug therapies, and four on acupuncture and acupressure. The largest and smallest samples had 303 and 24 patients, respectively. Length of treatment ranged from one to six months and the measures most commonly used in the studies were the visual analogue scale and clinical efficacy. Reported complications included gastrointestinal events, nausea, vomiting, diarrhea, abdominal pain, and liver and kidney disorders. CONCLUSION Medicinal plants, drugs, and acupressure seem to suppress pain by reducing the level of prostaglandins, mediating nitric oxide, increasing beta-endorphin levels, blocking the calcium channel, and enhancing circulatory flow through the uterine pathway. Further trials are required to confirm the benefits of the procedures described and ensure the absence of complications.

Abstract
BACKGROUND The first-line strategy for the treatment of obesity is weight loss (WL) through decreasing calorie intake. However, a diet that is capable of attenuating fat free mass decline following WL is preferred. Furthermore, it is required to choose proper measurements and appropriate obesity-assessment indices to monitor weight and body composition during WL program. METHODS A total of 68 adults with overweight and/or obesity underwent a WL program (rapid and slow WL). Dependent variables include: weight, resting metabolic rate (RMR), body composition, and related measurements such as waist circumference (WC), waist to height ratio (WHtR), body adiposity index (BAI), a body shape index (ABSI), fat mass to lean body mass (FM/LBM), and percentage body fat (PBF). RESULTS Obesity measurements decreased in both groups (all P < 0.05) while LBM and RMR decreased more in the rapid WL group (P < 0.05). After age and sex adjustment, a robust correlation was observed between FM/LBM and PBF (r = 0.918), LBM% and PBF (r = -0.949), LBM% and FM/LBM (r = -0.904), WHtR and WC (r = 0.986), and BAI% and HC (r = 0.986) (P < 0.001 for all correlations). FM has the highest correlation with WHtR among other indices (r = 0.706). CONCLUSIONS Compared to fast WL, our data support that slow and gradual WL is more effective to improve body composition and obesity-assessment indices. The robust relationship was observed between FM and WHtR, among other indices such as BMI or ABSI. Therefore, in order to evaluate FM, where the FM is not measurable, the WHtR might be the reasonable index.

Abstract
Several studies have been conducted regarding the prevalence of Chlamydia trachomatis, Mycoplasma hominis, and Ureaplasma urealyticum in pregnant Iranian women. However, it is necessary to combine the previous results to present a general assessment. We conducted the present study based on systematic review and meta-analysis studies according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched the national and international online databases of MagIran, IranMedex, SID, MedLib, IranDoc, Scopus, PubMed, ISI Web of Knowledge, and Google Scholar search engine for certain MeSH keywords until June 16, 2017. In addition, heterogeneity, sensitivity analysis, subgroup analysis, and publication bias were performed. The data were analyzed using random-effects model and Comprehensive Meta-Analysis version 2 and P value was considered lower than 0.05. The prevalence of Chlamydia trachomatis in 11 surveyed articles that assessed 2864 pregnant Iranian women was 8.74% [95% confidence interval (CI): 5.40-13.84]. The prevalence of Chlamydia trachomatis was estimated 5.73% (95% CI: 2.09-14.73) and 13.55% (95% CI: 11.23-16.25) by enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR), respectively which the difference was not significant (P=0.082). The lowest and highest prevalence of Chlamydia trachomatis was estimated in Tehran province [4.96% (95% CI: 2.45-9.810)] and Ardabil province [28.60% (95% CI: 20.61-38.20)], respectively. This difference was statistically significant (P<0.001). Meta-regression for the prevalence of Chlamydia trachomatis based on year of the studies was significant with increasing slope (P=0.017). According to the systematic review, the prevalence of Mycoplasma hominis and Urea plasma urealyticum indicated 2 to 22.8% (from 4 articles) and 9.1 to 19.8% (from 3 articles), respectively. There was no evidence of publication bias (P value for Begg and Eggers' tests was 0.161 and 0.173, respectively). The prevalence of Chlamydia trachomatis is high among pregnant Iranian women. Screening pregnant women as part of preventive measures seem necessary considering the potential for maternal and fetal complications.

Abstract
BACKGROUND The probability of HIV transmission through contaminated blood and blood products is eye catching. 5%-10% of blood products are contaminated with HIV. Therefore, it is essential to provide safe blood supply to prevent transmission of infectious diseases. Current systematic review and meta-analysis was conducted to evaluate the weighted prevalence of HIV in Iranian blood donors. METHODS This study was reported according to PRISMA checklist for systematic reviews and meta- analysis. Required data were collected by using key words such as "HIV", "blood donation" OR "blood donors", "epidemiology" OR "prevalence", "blood transfusion" and "Iran", in international databases including PubMed, Scopus, Web of Science, Cochrane, Embase and national databases including Magiran, IranMedex and Scientific Information Databank. Papers were searched until December 2017. Cochran's Q test and I2 index were used to assess the heterogeneity among studies. RESULTS A total of 49 studies including 5403170 donors entered this meta-analysis. According to analysis, the prevalence of HIV-positive patients among Iran blood donors was estimated 7.9/100000 (95% CI: 0.000052-0.000121%). The highest prevalence was related to the central region of Iran (11.3/100,000 [95% CI:0.000063-0.0002%]) and Kermanshah province (49.2/100000 [95% CI:0.000273-0.000888%]) and the lowest prevalence was related to the eastern region (1/100000 [95% CI:0.000001-0.000072%]) and Khorasan Razavi province (0.9/100000 [95% CI:0.000001-0.000139%]. CONCLUSION The overall HIV prevalence in Iranian blood donors is low and satisfying. However, the high prevalence in some regions and provinces should be reviewed more meticulously.

Abstract
Abstract
Background
Fertility and infertility problems are among the complex issues in medicine. The use of herbal products in the treatment of fertility has been considered as an alternative to synthetic drugs. Celery containing known compounds can have an impact on the fertility rate. The aim of this study was to do a systematic review on conducted studies in conjunction with the celery and reproduction.
Methods
Required papers were searched from databases like Science direct, PubMed, Scopus, and Springer. Keywords used in this study were “Apium graveolens L.”, “fertility”, “reproductive system”, “sperm”, “testis”, “delivery”, “sexual hormone”, “LH”, “FSH”, “testosterone”, “semen”, “male”, and “female”. Out of 238 collected articles (published in the period 1995 to 2015), 222 were excluded due to non-relevance and lack of access to the original article.
Results
The notable points were the different results seen by different researchers during different treatment periods or at different doses. Of the 16 studies reviewed in this study, 13 studies have mentioned the positive effect of celery on fertility, while three studies reported the inhibitory effects of this plant.
Conclusions
Celery can have protective effects against substances such as sodium valproate, propylene glycol, and diethyl phthalate causing damages to the testicular structure and spermatogenesis. In this regard, the doses used and the treatment time while using the plant must be accurately investigated. Since there are compounds such as apigenin, the celery can induce inhibitory effects on fertility in case of chronic use or high concentration.

Abstract
INTRODUCTION Food allergy refers to abnormal reactions of the body caused by an immune system response to food. This study was conducted aiming to investigate allergy to food allergens in children with food allergies. MATERIALS AND METHODS This study was conducted as a cross-sectional one on 304 children aged six months to seven years with food allergies admitted to the tertiary referral hospital in Kurdistan Province - Iran, during 2014-2015. All the patients were examined for skin prick test using 49 allergens. Finally, the obtained data were analysed using SPSS15 and chi-square and t tests. RESULTS The highest percentage of occurrence of bump reaction (wheal) and redness (flare) was due to the consumption of fish, eggs, tomatoes, and cocoa. Moreover, the lowest rate of wheal and flare was caused by exposure to allergens like latex, tea, malt, and wheat flour. The reaction most created due to the consumption of foods was flare which was higher among under three-year-olds group (p<0.05), and between the sexes, girls showed the most common allergic reactions (p<0.05). CONCLUSION Since food allergy has a high prevalence in children, it should be considered with great interest. Considering that avoiding food allergens is the first step in the treatment of food allergies, the present study may be a useful guide in this regard.

Abstract
Plants are an important source of natural active products that are different, based on mechanism and biological properties. Celery (Apium graveolens L) is a plant from the apiaceae family and phenolic and antioxidant compounds of this plant have been studied by several scientists. The aim of this study was to review systematically the antioxidant activity of celery. Required articles were searched from databases such as Science Direct, PubMed, Scopus, and Springer. Keywords used in this study were Apium graveolens L, celery, antioxidant, free radical, leaf, and seed. Out of 980 collected articles (published in the period 1997-2015), 9 studies finally met the inclusion criteria and were considered. Celery, because of compounds such as caffeic acid, p-coumaric acid, ferulic acid, apigenin, luteolin, tannin, saponin, and kaempferol, has powerful antioxidant characteristics, to remove free radicals. It is clear that celery, with different compounds and diverse concentration can have varied healing effects. It is suggested that the next studies concentrate on other therapeutic and industrial attributes of celery.

Abstract
INTRODUCTION Asthma is one of the diseases which has a high prevalence in developed and developing countries. The relationship between asthma and obesity has always been focused by researchers. In this field, adipokines, especially adiponectin and leptin have highly attended by the scientist. The aim of this study was to determine the serum level of adiponectin, leptin and the leptin/adiponectin ratio in asthmatic patients and its relationship with disease severity, lung function and BMI (body mass index). METHODS In this cross-sectional study, 90 asthmatic women admitted to the tertiary referral hospital in Kurdistan province - Iran, were examined. First, BMI was measured and then pulmonary function tests were performed in all asthmatics patient. Forced expiratory volume in 1s (FEV1), forced vital capacity (FVC), and FEV1/FVC, were measured. At the end, blood samples were collected and serum level of adiponectin and leptin were measured by ELISA method. RESULT Serum leptin and leptin/adiponectin levels correlated positively with asthma severity and BMI (p=0.0001), but there was no correlation between adiponectin level with asthma severity and BMI (p>0.05), also serum leptin and leptin/adiponectin levels inversely correlated with FEV1 and FVC in patient (p=0.0001). CONCLUSION Asthma is linked with obesity, and there is an association between asthma severity and BMI with serum leptin and leptin/adiponectin levels, but our results do not support a significant role of adiponectin in obesity or asthma.

Abstract
Cancer is the second cause of death after cardiovascular diseases. With due attention to rapid progress in the phytochemical study of plants, they are becoming popular because of their anticancer effects. The aim of this study was to investigate the effective medicinal plants in the treatment of cancer and study their mechanism of action. In order to gather information the keywords “traditional medicine,” “plant compounds,” “medicinal plant,” “medicinal herb,” “toxicity,” “anticancer effect,” “cell line,” and “treatment” were searched in international databases such as ScienceDirect, PubMed, and Scopus and national databases such as Magiran, Sid, and Iranmedex, and a total of 228 articles were collected. In this phase, 49 nonrelevant articles were excluded. Enhancement P53 protein expression, reducing the expression of proteins P27, P21, NFκB expression and induction of apoptosis, inhibition of the PI3K/Akt pathway, and reduction of the level of acid phosphatase and lipid peroxidation are the most effective mechanisms of herbal plants that can inhibit cell cycle and proliferation. Common treatments such as radiotherapy and chemotherapy can cause some complications. According to results of this study, herbal extracts have antioxidant compounds that can induce apoptosis and inhibit cell proliferation by the investigated mechanisms.

Abstract
INTRODUCTION Asymptomatic Toxoplasma gondii transmitted from blood donors to receiving patients has become a concern. Numerous articles have been published on the epidemiology of T. gondii in blood donors in Iran and a systematic review of the results shows quite different findings, hence this study was conducted to determine the seroprevalence of T. gondii in Iranian blood donors using meta-analysis. METHODS We searched for epidemiological studies that were published until July 2016 in eight English databases including: Scopus, PubMed, Ovid, Science Direct, Cochrane, Web of Science, Springer, Wiley Online Library, and four Iranian databases: Magiran, Iranmedex, SID and Medlib as well as Google Scholar. To estimate pooled estimator, regarding high heterogeneity and significance of I2 index, Random effects model was used. Data analysis was conducted using Review Manager Ver5.3.5 and P<0.05 was considered significant. RESULTS Among 10 studies with a sample size of 4538 Iranian blood donors, the seroprevalence of T. gondii was calculated to be 34.4% (CI95%: 24.9-43.9). The rate in males and females was 33.36% (CI95%: 19.92-46.81) and 37.63% (CI95%: 20.81-54.45), respectively. The seroprevalence of IgM and IgG antibodies among blood donors were 2.74% (CI95%: 0.55-4.92) and 31.84% (CI95%: 20.61-43.08), respectively. The seroprevalence of T. gondii was significantly associated regarding blood group (P=0.04), but this relation was not significant with blood transfusion (P=0.62). CONCLUSION The results of this review indicate a high seroprevalence of T. gondii (about one-third) in Iranian blood donors and emphasizes the importance of screening the seroprevalence of T. gondii of donated blood in Iranian Blood Transfusion Organization.

Abstract
Background: Cervical cancer is the fourth leading cause of cancer death in women worldwide. Persistent infection with a high risk human papillomavirus (HR-HPV) is the main etiological factor, so that early early detection of HR-HPV is very important. The aim of this study was to investigate the efficacy of Care™ HPV, a new method, as compared with Pap smear, PCR, and biopsy for screening purposes. Material and Method: In this cross-sectional study, 200 sexually active women aging from 25-50 years referred to the oncology clinic of Shahid Sodoughi Yazd Hospital in 2015 with a variety of cervix epithelial lesions or a need for colposcopy were enrolled. Results for Care™ HPV test (cervical), Pap smear, PCR, and biopsy were analyzed using SPSS 15 software and chi-square test, McNemar, and ROC curve analysis. Qualitative variables were compared using a Chi-square test. Results: Care™ HPV test sensitivity in detecting cervical intraepithelial neoplasia grade II (CIN-II) and also positive and negative predictive values were higher as compared to with other tests (p<0.05). The Pap smear test specificity was highest. There was no significant differences between Care™ HPV and PCR tests regarding detection of HPV-DNA in cases of CIN-II and worse (p>0.05). Conclusion: The Care™ HPV test has high sensitivity and predictive values for detecting HPV infection, with higher efficacy than the Pap smear test for tracking CIN-II. Therefore it may be recommended for use as a screening test in low-income areas.

Abstract
BACKGROUND During abdominal surgery under regional anesthesia, nausea may happen due to several contributing factors. This study compared the effects of ondansetron and dexamethasone on nausea and vomiting under spinal anesthesia. METHODS One hundred and twenty patients of 15 to 35 years old with ASA class I and II were enrolled. Before administering either ondansetron or dexamethasone, blood pressure and heart rate of the patients were recorded. The patients received 70 mg of 5% lidocaine for spinal anesthesia. Patients who received 6 mg of ondansetron were considered as group A, while group B received 8 mg of dexamethasone. The level of nausea and vomiting, blood pressure, heart rate and respiratory rate of each patient was measured at 1, 5, 10, 15 and 30 minutes after spinal anesthesia and during recovery (every 5 minutes). RESULTS There was a significant difference between nausea and vomiting between the two groups after spinal anesthesia within the first and fifth minutes. There was no significant difference between nausea and vomiting between the two groups within 10, 15 and 30 minutes and during recovery at 5, 10, 15 and 30 minutes. CONCLUSION Dexamethasone and ondansetron were shown to equally reduce the incidence of nausea and vomiting under spinal anesthesia and can be recommended as a good choice for prevention of nausea and vomiting during surgeries.

[PMID: 27909455 PMCID: PMC5128352 DOI: 10.4306/pi.2016.13.6.637] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2015] [Revised: 01/04/2016] [Accepted: 02/12/2016] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE The purpose of this study was to evaluate the salivary testosterone levels under psychological stress and its relationship with rumination and five personality traits in medical students. METHODS A total of 58 medical students, who wanted to participate in the final exam, were selected by simple random sampling. Two months before the exam, in the basal conditions, the NEO Inventory short form, and the Emotional Control Questionnaire (ECQ) were completed. Saliva samples were taken from students in both the basal conditions and under exam stress. Salivary testosterone was measured by ELISA. Data was analyzed using multivariate analysis of variance with repeated measures, paired samples t-test, Pearson correlation and stepwise regression analysis. RESULTS Salivary testosterone level of men showed a significant increase under exam stress (p<0.05). However, a non-significant although substantial reduction observed in women. A significant correlation was found between extroversion (r=-0.33) and openness to experience (r=0.30) with salivary testosterone (p<0.05). Extraversion, aggression control and emotional inhibition predicted 28% of variance of salivary testosterone under stress. CONCLUSION Salivary testosterone reactivity to stress can be determined by sexual differences, personality traits, and emotional control variables which may decrease or increase stress effects on biological responses, especially the salivary testosterone.

The relationship between serum levels of vitamin D with asthma and its symptom severity: A case-control study. Allergol Immunopathol (Madr) 2016; 44:547-555. [PMID: 27477034 DOI: 10.1016/j.aller.2016.04.016] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2016] [Revised: 04/15/2016] [Accepted: 04/27/2016] [Indexed: 12/23/2022]
Abstract
BACKGROUND Asthma is a heterogeneous disease characterised by chronic inflammatory airways, and is affected by several immunological factors. One of the most discussed and researched hypotheses is the relationship between vitamin D serum levels with asthma. This study aimed to investigate the relationship between vitamin D serum levels with asthma and pulmonary functions in children in Kurdistan province, Iran. MATERIALS AND METHODS In this case-control study, 120 children ranging from 6 to 18 years were referred in summer for investigation. Participants were divided into two groups: asthma group, N=60; and control group, N=60. After serum separation, samples were analysed using vitamin D ELISA kit. Additionally, pulmonary function test and serum IgE levels were measured in both groups. Data were analysed using Chi-square test and multiple regression analysis in SPSS15. RESULTS No difference was shown between the groups in terms of gender composition (male: 57.5; female: 42.5) (P>0.05). Average Vitamin D serum level in the case group (17.98±8.68) was less than in control group (22.35±6.26) (P<0.01). In addition, the difference of vitamin D deficiency in level of suboptimal between the asthma (17.77±6.41) and the control group (24.9±3.18) was statistically significant (P<0.0001). Positive correlation existed between vitamin D levels with FEV1, FVC, and FEV1/FVC. Multiple regression analysis showed a reverse relationship between vitamin D levels with IgE serum levels; this remained after adjustment for potential confounders (e.g. age, sex, BMI, FEV1, and FVC). CONCLUSION The results showed that serum levels of vitamin D in asthma patients were less than in healthy people, and also reduced lung function in these patients. So, the serum levels of vitamin D in asthma patients must be checked continuously.

Abstract
Introduction: The study aimed to investigate the anti-fertility effect of fennel (Foeniculim vulgare Mill) seed extract in male rats.
Material and Methods: Forty Wistar rats were divided into five equal groups. The control group received distilled water and the experimental groups were orally administered 1 ml of hydro-alcoholic extract of fennel seed in four doses of 35, 70, 140, and 280 mg/kg/b.w. daily for 60 days. After the last gavage, the rats were anaesthetised and the caudal part of the right epididymis was used for sperm counting. After fixation of the testes, microscopic sections were prepared and histological changes were evaluated.
Results: The number of spermatogonia after doses of 140 and 280 mg/kg and Sertoli cells after a dose of 140 mg/kg decreased significantly as compared with the control group (P < 0.05). The number of primary spermatocytes and sperm count decreased significantly in the experimental groups (70, 140, and 280 mg/kg) when compared to the control group (P < 0.05). Furthermore, thickening of the basement membrane, cell apoptosis, and irregular arrangement of the germinal epithelium were observed in the experimental groups.
Conclusion: Hydro-alcoholic fennel seed extract at these doses could reduce reproductivity and has anti-fertility activity in male rats.

Abstract
INTRODUCTION Regarding the functioning of the endocrine system, and especially in the thyroid of patients with thalassemia, multiple studies in different parts of the world have reported conflicting results. The aim of this study was to assess the levels of thyroid hormones and TSH in beta-thalassemic patients in the city of Ahwaz. METHODS In this matched case-control study, 105 patients in the case group and 105 subjects as controls were randomly selected from clients referred to the Abuzar hospital in 2015-2016. Serum levels of T3, T4, and TSH hormones were measured using ELISA. Data was processed with the SPSS15 software and tested by using independent t-tests and logistic regression. RESULTS The study results showed that the serum level of T3 hormone did not significantly differ between the two groups (p> 0.05). Whereas the serum level of T4 was lower in the case group, compared to the controls, which was statistically significant (p <0.05). The serum level of thyroid stimulating hormone (TSH) in the case group was higher than the control group, and this difference was statistically significant (p <0.05). Logistic regression analysis showed significant differences in serum levels of T4 (OR: 0.58) and TSH (OR: 1.57) between the case and control groups (p<0.05). CONCLUSION Hypothyroidism is clear in patients with beta thalassemia. With regard to the possible effect of iron on the disorder, a blood transfusion schedule should be performed at intervals, and the desferal injection program should be done regularly to prevent hemochromatosis in patients with thalassemia major due to the effect of accumulation of iron on thyroid function and detection of hypothyroidism. This course of action will prevent incidence of this complication in patients with thalassemia major.

Abstract
In today’s stressful world, psychopathy (especially anxiety) is receiving increased importance. Most of the drugs used to treat this disease have several side effects. Medicinal plants derived from natural products have fewer side effects and can be used in the treatment of this disease. The aim of this study was to evaluate the effect of the hydroalcoholic extract of Rosmarinus officinalis L. on anxiety in mice. In this experimental study, 50 male mice were randomly divided into 5 groups. To evaluate anxiety, the Elevated Plus Maze test was performed. The control group received normal saline, the positive control group received diazepam (1 mg/kg) as intraperitoneal injection, and the experimental groups received doses of 100, 200, and 400 mg/kg body weight of rosemary extract. The data were analyzed using SPSS 15 and ANOVA statistical tests. The results show that rosemary extract dose-dependently increases the mice spending time and the entries number of mice in plus maze open arms (indicating less stress). This effect at a dose of 400 mg/kg was similar to diazepam, which, in comparison to the control group, was statistically significant ( P < .01), while the evaluation of locomotor activity in treated groups, compared with the control groups, showed no significant difference ( P > .05). On the other hand, the rosemary extract, similar to the standard drug diazepam, showed an anti-anxiety effect. This effect is probably due to the presence of flavonoids in this plant and their antioxidant property.

Abstract
Transfusion-transmissible infections include pathogens that may cause severe and debilitating diseases. Toxoplasmosis is a cosmopolitan neglected parasitic infection that can lead to severe complications including death in immune-compromised patients or following infection in utero. Multiple studies have demonstrated the transmission of Toxoplasma gondii by blood transfusion. The objective of this review was to comprehensively assess the seroprevalence rate of Toxoplasma in blood donors from a worldwide perspective. Seven electronic databases (PubMed, Science Direct, Web of Science, Scopus, Cochrane, Ovid, and Google Scholar) were searched using medical subject headings terms. A total of 43 records met the inclusion criteria in which 20,964 donors were tested during the period from January 1980 to June 2015. The overall weighted prevalence of exposure to toxoplasmosis in blood donors was 33% (95% confidence interval [CI], 28%-39%). The seroprevalences of immunoglobulin (Ig)M and both IgG and IgM antibodies were 1.8% (95% CI, 1.1%-2.4%) and 1.1% (95% CI, 0.3%-1.8%), respectively. The highest and the lowest seroprevalences of toxoplasmosis were observed in Africa (46%; 95% CI, 14%-78%) and in Asia (29%; 95% CI, 23%-35%), respectively. Brazil (75%) and Ethiopia (73%) were identified as countries with high seroprevalence. Because positive serology does not imply infectiousness and because seroprevalence is high in some nations, a positive serology test result alone cannot be used as an effective method for donor screening. Future research for methods to prevent transfusion-transmitted toxoplasmosis may derive benefit from studies conducted in areas of high endemicity.

Abstract
BACKGROUND The aim of this study was to investigate the effect of Hemiscorpius lepturus venom on leukocytes and the leukocyte subgroups in peripheral blood of rat. METHODS In this experimental study, sixty N-Mari rats were divided into three groups of 20 rats. Then the rats in each group were divided into four subgroups based on the blood sampling time that was 2, 6, 24 and 48 hours after the venom injection, respectively. The control group did not receive anything, however, the first and the second experimental groups received 0.1 and 0.01mg/kg of venom, subcutaneously. In accordance with a designated four sampling times, the blood sampling was carried out in three groups. After RBC lysis, the leukocytes and leukocyte sub-populations were determined and counted using appropriate hematological standard methods. RESULTS The leukocyte and the neutrophil count at two (P<0.05), six (P<0.01) and 24 (P<0.05) hours after the venom injection showed a significant decline compared with the control group, this decrease was significant at the dose of 0.1 mg/kg until 48 hours after the venom injection (P<0.05). The lymphocyte count showed a significant decline throughout the all hours of the experiment, compared with the control group (P<0.05). CONCLUSION Leukocytes are probably affected by the cytotoxicity effect of the H. lepturus venom in a dose-dependent manner. This could be a wakeup call for the medical staff to perform quick and accurate treatment in the least time possible.

Abstract
INTRODUCTION Diabetes is a serious metabolic disorder and plenty of medical plants are used in traditional medicines to treat diabetes. These plants have no side effects and many existing medicines are derived from the plants. The purpose of this systematic review is to study diabetes and to summarize the available treatments for this disease, focusing especially on herbal medicine. METHODS Required papers about diabetes and effective plants were searched from the databases, including Science direct, PubMed, Wiley, Scopus, and Springer. Keywords in this study are "medicinal plants", "diabetes", "symptom", "herbal", and "treatment". Out of the 490 collected articles (published in the period between 1995 and 2015), 450 were excluded due to non-relevance or lack of access to the original article. RESULTS Diabetes is mainly due to oxidative stress and an increase in reactive oxygen species that can have major effects. Many plants contain different natural antioxidants, in particular tannins, flavonoids, C and E vitamins that have the ability to maintain β-cells performance and decrease glucose levels in the blood. CONCLUSION According to published results, it can be said that medical plants are more affordable and have less side effects compared synthetic drugs, and are more effective in treatment of diabetes mellitus.

Abstract
Background: Rubella is a mild viral infection affecting women of reproductive age, and the fetus in early pregnancy, leading to miscarriage, stillbirth and Congenital Rubella Syndrome. Objectives: The present study aimed to assess serum level of anti-rubella antibodies in women younger than 25 years attending medical centers in Ahvaz city. Patients and Methods: This descriptive cross-sectional study was conducted on 760 women younger than 25 years attending medical centers in Ahvaz. A sample of 3 mL of venous blood was taken from each woman and ELISA method was used to assess anti-rubella IgG levels. Antibody level more than 11 IU/mL was considered safe. Data was analyzed by SPSS software using Chi-square, ANOVA and Pearson Correlation tests. Results: Of total samples, 683 women (88.9%) had immunity against rubella, 80 (10.4%) no immunity and 5 (0.7%) intermediate levels of antibody. Immunity to rubella increased significantly with aging (P = 0.001) and a significant association was found between age and antibody titer (P = 0.001, r = 0.261). Conclusions: More than 95% of 15 to 25 year-old women (main reproductive age in Iran) are within acceptable immunity range. Level of immunity to rubella in women of reproductive age in this region appears satisfactory.

Abstract
Increase in cases of various cancers has encouraged the researchers to discover novel, more effective drugs from plant sources. This study is a review of medicinal plants in Iran with already investigated anticancer effects on various cell lines. Thirty-six medicinal plants alongside their products with anticancer effects as well as the most important plant compounds responsible for the plants’ anticancer effect were introduced. Phenolic and alkaloid compounds were demonstrated to have anticancer effects on various cancers in most studies. The plants and their active compounds exerted anticancer effects by removing free radicals and antioxidant effects, cell cycle arrest, induction of apoptosis, and inhibition of angiogenesis. The investigated plants in Iran contain the compounds that are able to contribute effectively to fighting cancer cells. Therefore, the extract and active compounds of the medicinal plants introduced in this review article could open a way to conduct clinical trials on cancer and greatly help researchers and pharmacists develop new anticancer drugs.

Abstract
BACKGROUND Medicinal plants have a long history in treating blood disorders, which is one of the most common problems in today's advanced world. Fennel (Foeniculum vulgare) is a medicinal plant with a high content of polyphenols and has antioxidant and immunomodulatory properties. OBJECTIVES The aim of this study was to evaluate the effect of hydro-alcoholic extract of fennel on some hematological indices in male rats. MATERIALS AND METHODS In this experimental study, thirty male Wistar rats were divided into six groups (five rats in each group). The first group (control) did not receive any dose; the second group (sham) received 1 mL normal saline (extraction solvent); and the experimental groups 1, 2, 3 and 4 respectively received 1 mL hydro alcoholic extract of fennel in four doses of 250, 500, 750 and 1000 mg/kg of body weight every 48 hours for 30 days by gavage. One day after the last gavage following induction of anesthesia and taking blood from the heart of rats, measurement of red and white blood cells, hemoglobin, hematocrit and tests of bleeding and coagulation time (CT) were performed. The data was analyzed by one-way ANOVA test using SPSS15 software. RESULTS Fennel increased mean RBC (7.54 ± 0.53 × 106) and WBC (5.89 ± 0.78 × 103) values, especially at a dose of 250 mg/mL and CT (2.45 ± 0.20) at a dose of 500mg/mL compared to the control group (P < 0.05). CONCLUSIONS Fennel increased red and white blood cells probably due to the presence of polyphenols and antioxidant activity of fennel and reduced negative effects of free radicals on blood cells.

Abstract
Background: Use of medicinal plants with high antioxidant properties could be effective to increase fertility and improvement of disorders such as hormonal imbalance, impotency, oligospermia and immotile sperm. Celery (Apium graveolens) is rich in antioxidant agents. The leaf and stems of celery contain phenols, furanocoumarin and luteolin. Apigenin is one of the main flavonoids of celery leaf. Objectives: This study aimed to investigate the effects of hydroalcoholic extract of celery on histological properties of testis and number of sexual cells in male rats. Materials and Methods: Thirty-two male Wistar rats were divided into four groups of eight rats each. Control, did not receive any medication; sham, received normal saline; and two groups received celery extract orally in dosages of 100 and 200 mg/kg/BW once every two days for 60 days. At the end, animals were anesthetized, and caudal part of the right epididymis was used for sperm counting. After fixation of testis, tissue sections were prepared and studied microscopically to evaluate morphometric (lumen diameter, number of primary spermatocyte and sertoli cell) and histological changes. Data was analyzed by one-way ANOVA test using SPSS15 software. P < 0.05 was considered as statistically significant. Results: There was a significant increase in the number of sperms, sertoli cells, and primary spermatocyte (P < 0.05) in groups receiving extract; however, structural changes were not observed in the groups. Conclusions: It seems that celery increases spermatogenesis in male rats, but has no destructive effects on testicular tissue.
