Abstract
Background: Cardiovascular disease (CVD) is the leading cause of mortality worldwide. Omega-3 fatty acids have been shown to have both anti-atherogenic and anti-inflammatory effects through inducing the expression and production of adipokines. Adipokines such as apelin, have been observed to play a protective role in the incidence and progression of CVD. The aim of this study was to assess the influence of omega-3 fatty acids supplementation on the serum apelin levels in patients with cardiovascular disease.
Methods: Forty-six male patients with CVD participated in the study. Patients were randomly allocated into two groups receiving either omega-3 fatty acids or a placebo. Participants received 4 g of omega-3 fatty acids (EPA: 720 mg, DHA: 480 mg) or a placebo (edible paraffin) for 8 weeks. Serum apelin levels, high sensitive C-reactive protein (hs-CRP), and lipid profiles were measured. Dietary intake, anthropometric parameters, body composition, systolic and diastolic blood pressure were evaluated before and after the 8 weeks of intervention. Statistical analyses were performed using SPSS version 22.
Results: Two participants from the placebo group withdrew from the study. Prior to the intervention, no significant differences were present between the two groups in age, body mass index, body composition, dietary intakes, lipid profiles and blood pressure. Compared to placebo, the intake of omega-3 fatty acids increased serum apelin levels (p= 0.018), decreased the levels of LDL cholesterol, and decreased serum hs-CRP concentrations (p= 0.007, p= 0.011 respectively). Additionally, the concentrations of VLDL, TG and hs-CRP (p= 0.037, p= 0.037 and p= 0.016 respectively) declined compared to baseline and final values in the omega-3 fatty acids group.
Conclusions: Omega-3 fatty acid supplementation increases serum apelin and HDL concentrations, while decreasing serum LDL-C and hs-CRP levels.

Abstract
Background: Evidence indicates that combined approaches based on exercise and nutrition benefit neural development. We aimed to determine the effect of saffron and endurance training on hippocampus neurogenic factors, neurotrophin-3 gene expression in soleus muscle, and short-term memory in Wistar rats.
Methods: The study analyzed four groups of ten rats each: control, exercise, saffron, and saffron plus exercise. The rats in the exercise groups were trained on a rodent motor-driven treadmill. All rats were gavage daily with either saffron extract (40 mg/kg) or water. After eight weeks of intervention all rats were evaluated using the novel object recognition (NOR) test. Blood and tissue samples were collected to measure proteins and neurotrophin-3 gene expression.
Results: Rats that received saffron treatment combined with exercise had significantly greater brain-derived neurotrophic factor (BDNF) and serotonin in hippocampus compared to the control and saffron-only-treated rats (p< 0.05). Neurotrophin-3 mRNA in soleus muscle was higher in the saffron plus exercise group than rats in the other three groups (p< 0.05). Hippocampus 5-hydroxyindolacetic acid and short-term memory were significantly greater in all the intervention groups than in the control group (p< 0.05).
Conclusions: Saffron, combined with endurance exercise, synergistically increased hippocampus BDNF, serotonin, and muscular neurotrophin-3 mRNA in Wistar rats.

Abstract
Background: Retinoic acid (RA) plays a key role in naïve T cell differentiation into FOXP3+ Treg cell in the respiratory airways. The present study aims to investigate RA and Treg-related cytokine serum levels, salivary IgA levels, FOXP3 and IL-4 gene expression, and the relationships between RA serum levels and Treg-related cytokines in allergic rhinitis (AR) patients and healthy controls.
Methods: Salivary IgA and serum IgE, RA, IL-10, and TGF-β concentrations were measured by ELISA in 37 AR patients and 30 age- and sex-matched healthy controls.
Results: IL-10 and TGF-β concentrations were significantly less in AR patients than in healthy controls (p< 0.01 and P< 0.0001, respectively). Salivary IgA was significantly greater in patients than in controls (p< 0.05). RA was not significantly different between patients and controls (p> 0.05); however, a significant positive correlation was found between serum RA and both IL-10 and TGF-β in AR patients.
Conclusions: Our data suggest that RA may influence AR risk via affecting the TGF-β and IL-10 production.

Abstract
Background: According to the studies, many pathogens function as cofactors interacting with Human papillomavirus in the development of pre-cancer or cancer of the cervix. The aim of this study was to investigate the prevalence rate of Sexually Transmitted Infections (STIs) pathogens including Mycoplasma hominis, Ureaplasma urealyticum, Chlamydia trachomatis, Neisseria gonorrhoeae, Gardnerella vaginalis, and Streptococcus agalactiae in people with HPV and without HPV infection, and frequency rate of these pathogens in high and low risk of HPV.
Methods: Cervical samples of 280 women who referred to Tehran west hospitals in Iran, between 2019 and 2020, were collected. After DNA extraction of samples, identification of HPV and genotyping was performed, and then, to detect each microorganism, the PCR was carried out with specific primers. Finally, the results were analyzed using descriptive statistics tests.
Results: The mean age of patients was 37 years. Two groups of patients were identified based on positivity or negativity of HPV. In HPV-positive group (118 cases), the prevalence of U. urealyticum, M. hominis, N. gonorrhoeae, G. vaginalis, and S. agalactiae was 38 (13%), 7 (62%), 5.93%, 19.49%, 0.84% respectively. In HPV-negative group (162 cases), rate of infection with U. urealyticum, M. hominis, N. gonorrhoeae, G. vaginalis, and S. agalactiae was 29.62%, 6.17%, 3.08%, 16.04%, 0.61% respectively. Among the two groups, there was only 1 patient with C. trachomatis (0.84%), seen in HPV-positive group.
Conclusions: In this study no significant association was found between HPV and bacteria such as G. vaginalis and S. agalactiae, and it was found that C. trachomatis, and especially N. gonorrhoeae are strongly associated with HPV infection.

Abstract
Background: Allergicrhinitis (AR) is an inflammatory disorder of the nasal mucosa, caused by exposure to environmental allergens. It is known that 15-lipoxygenase (15-LOX) is involved in the biosynthetic pathways of anti-inflammatory lipid mediators, including resolvins and protectins.
Methods: In this study, which was performed on 130 AR patients and 130 healthy controls, we aimed to investigate the association of susceptibility to AR with two selected single-nucleotide polymorphisms (SNPs), that is, rs2619112:A>G and rs7217186:C>T, in the intron regions of arachidonic acid 15-LOX (ALOX15) gene, using SNPinfo and Regulome DB tools.
Results: The results showed that the CT genotype of rs7217186: C>T was significantly associated with the increased risk of AR compared to the CC genotype (P= 0.037, OR=1.943, CI: 1.038-0.638). However, there was no strong evidence of the association of rs2619112: A>G with susceptibility to AR (P> 0.05).
Conclusions: The present results indicated that rs7217186 polymorphism of ALOX15 gene might be a potential biomarker for susceptibility to AR.

Abstract
Background: Type 2 diabetes mellitus (T2DM) poses a significant public health challenge due to its high prevalence. Diabetic nephropathy (DN) is one of the most severe complications associated with T2DM. Early prediction of DN in patients with T2DM can significantly aid in managing this disease. This study takes an approach by investigating the potential role of melatonin and thyroid hormone levels as predictive biomarkers for the progression of diabetic nephropathy in individuals diagnosed with type 2 diabetes mellitus.
Methods: Our cross-sectional study involved 120 male participants, divided into two groups: 60 patients with T2DM and 60 with DN. The Cobas technique was used to measure serum thyroid hormone levels and quantified melatonin levels using an enzyme-linked immunosorbent assay (ELISA). A receiver utilizing characteristic (ROC) curve analysis to evaluate the predictive value of serum melatonin for DN was performed.
Results: No notable disparities in thyroid function tests were observed between diabetic patients with and without DN. However, the average serum melatonin quantity in patients with DN. (177.25 ± 60.48 pg/mL) was drastically lower in those with T2DM without DN (199.9 ± 55.16 pg/mL). The sensitivity and specificity of melatonin in predicting DN were 78% and 76%, respectively, with an optimal cut-off value of 178 pg/mL.
Conclusions: Serum melatonin levels exhibited a notable reduction. among individuals who were diabetic with DN, suggesting its potential utility as an additional predictive marker for developing DN in patients with T2DM.
