Abstract
PURPOSE Oxidative stress in chronic hyperglycemia could injure the tissues and onset of diabetes-related complications like retinopathy and neuropathy. This study investigates the association between methylenetetrahydrofolate reductase (MTHFR) and glutathione peroxidase (GPx) genetic variants with these complications. METHODS In this case-control study, 400 individuals, including 100 healthy subjects and 300 patients with type 2 diabetes mellitus (T2DM) in three subgroups: with retinopathy(n = 100), with neuropathy(n = 100), and without complication (n = 100) from West Iran, were studied. MTHFR (rs1801133) and GPx-1 (rs1050450) variants were identified by the PCR-RFLP method. The plasma levels of GPx activity, glutathione, malondialdehyde (MDA), total antioxidant capacity (TAC), and total oxidative stress (TOS) were measured by chemical methods. RESULTS Higher BMI, TOS and MDA levels were observed in patients with neuropathy compared to other patients and controls. Diabetic patients with neuropathy had lower levels of glutathione (7.8 ± 4.5; P < 0.001), GPx activity (39.5 ± 8.5; P < 0.001), and TAC (703.1 ± 129.1; P = 0.0001) in comparison with other groups. The patients without complication and retinopathic patients had higher plasma levels of glutathione (12.2 ± 2.4; p = 0.02) and TAC (793.4 ± 124.6; P < 0.001), respectively. MTHFR TT genotype significantly correlated with lower levels of TOS (3.5 ± 1.1; P < 0.001) and OSI (0.0050 ± 0.001; P < 0.001). Subjects with the GPx-1 TT genotype had higher levels of MDA (6.8 ± 2.5; P = 0.02) and lower levels of TOS (3.7 ± 1.6; P < 0.001), which is statistically significant. TT genotype of MTHFR was associated with 3.9 fold (95% CI 1.04-4.76; P = 0.0436) increased risk of neuropathy. Also, GPx-1 CT genotype increased the risk of retinopathy [OR = 2.7 (95% CI = 1.38-5.44; P = 0.0039)]. CONCLUSION The MTHFR TT genotype increased the risk of neuropathy in diabetic patients significantly. The GPx-1 CT genotype is related to increased retinopathy risk among diabetic patients. Both MTHFR and Gpx-1 TT genotypes were associated with higher BMI levels.

Abstract
Background: The objective was to elucidate the potential epigenetic regulatory mechanism in HMOX1 expression in preeclampsia. Materials & methods: HMOX1 promoter DNA methylation was evaluated in the placental tissue and blood of preeclamptic and normotensive pregnant women. HMOX1 and miR-153-3p gene expression were assessed in placental tissue and peripheral blood mononuclear cells (PBMCs). Related microarray datasets in the Gene Expression Omnibus database were also analyzed. Results: In placental tissue, despite HMOX1 expression downregulation, there was no significant change in HMOX1 methylation. In PBMCs, there was no significant alteration in HMOX1 expression, while hypomethylation was observed in blood. The miR-153-3p expression increased in the placental tissue and in the PBMCs of preeclampsia. Conclusion: DNA methylation does not affect HMOX1 expression, while miR-153-3p might be a biomarker for preeclampsia.

Abstract
BACKGROUND AND AIMS Preeclampsia (PE) is a serious medical condition that usually causes high blood pressure and affects multiple organs. Considering the adverse effect of oxidative stress on the process of PE in pregnant women and regarding the role of the Nrf2 gene in placental oxidative pathways, this study was conducted to investigate the DNA methylation status of Nrf2 in PE and healthy pregnant women. MATERIALS AND METHODS The present case-control study consisted of 70 PE and 70 healthy pregnant women. Blood and placenta samples were taken from all subjects, and the percentage of the Nrf2 gene methylation in the samples was assessed by the Methyl Light PCR method. Also, the Nrf2 gene expression was evaluated by real-time PCR. The total antioxidant capacity (TAC) and total oxidative status (TOS) were measured by the colorimetric method. RESULTS In PE women, there was a significant increase in blood pressure, term of pregnancy, and BMI. In addition, there were enhanced Nrf2 DNA methylation percentage in placenta tissue and increased TOS levels in placenta tissue and blood compared to healthy pregnant women (P < 0.05). Also, in the PE group, there was a significant decrease in Nrf2 gene expression and TAC level in placenta tissue compared to the control group (P < 0.05). CONCLUSION The Nrf2 gene undergoes epigenetic modifications of DNA hypermethylation in the PE placenta. Decreased expression of this gene and the changes in the level of oxidative parameters (TAC, TOS) confirm it.

Abstract
In recent decades, colorectal cancer (CRC) has turned into one of the most widespread malignancies, and the incidence of this malignancy is expected to increase. Despite considerable improvements in therapeutic approaches, the prognosis, and the management of CRC face many problems. Likely, the main limitation in the successful treatment of CRC is the lack of appropriate clinical therapeutic targets. As an effective target, the signal transducer and activator of transcription 3 (STAT3) are regulated by a wide range of genes and involved in cellular processes, including cell growth, migration, invasion, immunosuppression, and angiogenesis. Aberrant regulation of STAT3 signaling leads to cellular dysfunction, diseases, and malignancies, including CRC. Consequently, targeting this signaling pathway is considered one of the therapeutic strategies used in CRC treatment. MicroRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are non-coding RNA molecules with partial or no protein-coding activity that participate in gene regulation at epigenetic, transcriptional, and post-transcriptional levels and regulate multiple signaling pathways, including STAT3 signaling (especially JAK/STAT). Therefore, these regulatory molecules are suggested to be very promising targets to present new insights into overcoming the limitations of conventional therapeutic strategies. Therefore, the current review study aimed to summarize the therapeutic and diagnostic significance of miRNAs and lncRNAs and their therapeutic and diagnostic significance related to the expression and activity of STAT3 in CRC.

Abstract
Preeclampsia is the most common and serious complication of pregnancy. Variants of Sirtuin-1 (SIRT1) as a key player in the regulation of oxidant/antioxidant signaling pathways might be involved in the pathogenesis of preeclampsia. In the present case-control study 300 women with and without preeclampsia were studied for SIRT1 variants (rs7895833, rs7069102, and rs2273773) and haplotypes. Also, the relationship of glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities and Zn, Cu, and Se levels to the polymorphisms were investigated. The SIRT1 rs7895833 A > G, rs7069102 C > G, and the rs2273773 C > T polymorphisms were associated with the risk of preeclampsia. We found the haplotypes G (rs7895833) C (rs7069102) C (rs2273773), GCC, and ACC compared to the AGT decreased the risk of preeclampsia. The risk haplotype of AGT was associated with higher GPx activity compared to the GCC haplotype. A significantly higher level of Cu and lower levels of Zn and Se in patients with preeclampsia compared to controls were detected. Also, a significantly lower SOD and higher GPx activity in preeclamptic patients compared to controls were found. The three risk genotypes of AA (rs7895833), GG (rs7069102), and TT (rs2273773) significantly decreased the Zn level and SOD activity, and the TT genotype (rs2273773) increased the Cu level in all studied women. The presence of rs7069102 polymorphism was associated with enhanced systolic blood pressure. For the first time, we indicated three SIRT1 polymorphisms and the AGT haplotype are risk factors for preeclampsia development. Also, SIRT1 variants and haplotypes affect the levels of antioxidant enzymes and their cofactors, complicating the pregnancy outcome.

Abstract
Hypertension (HTN) is a global health challenge and increase the risk of cardiovascular disease. Hypertension has a multifactorial course of evolution, with both genetic and environmental factors playing an important role. To date, a number of genes and pathways have been proposed to be associated with HTN, among which is Nitric Oxide pathway. NO levels can be regulated by reactive oxygen species (ROS), superoxide and post-transcriptional mechanisms, including sense-anti sense interactions. NOS3AS gene encodes an antisense RNA (sONE) which is complementary to NOS3 transcript in 662 nucleotides and may regulate NOS3 in a post-transcriptional manner. In this study, we sought to define the role of NOS3AS in the pathophysiology of essential HTN. A total of 131 cases with hypertension and 115 controls were enrolled in the study. Peripheral blood was drawn from all study participants after signing the informed consent form. Three variants (rs71539868, rs12666075 and rs7830) were investigated by Tetra-ARMS PCR method. The results were then statistically analyzed. We found statistically significant association between rs7830 TT genotype, rs12666075 GT and TT genotypes with susceptibility to HTN. We failed to observe association between rs71539868 and susceptibility to HTN. The present study showed a strong association between NOS3AS variants and susceptibility to hypertension in the population of Kermanshah province. Our results may shed more light on the mechanisms of disease development and may also help to better identify genetic predispositions and individuals at risk.

Abstract
PURPOSE We aimed to study insertion/deletion (I/D) variation (rs4646994) of ACE gene in a group of SLE patients in west of Iran and its possible relationship with oxidative stress. METHOD AND RESULTS Genotypes and allele frequencies related to ACE (I/D) variation were determined in 108 SLE patients and 110 gender and age-matched healthy controls using PCR. Neopterin, malondialdehyde (MDA), and serum lipid concentrations were determined by HPLC and enzyme assay respectively. The overall distribution of ACE I/D genotypes in SLE patients was different from that of the control group (P = 0.005). DD genotype compared to ID genotype increased the risk of SLE (OR = 2.57, 95% CI 1.4-4.8, P = 0.003). ID genotype compared to the II genotype decreased the risk of disease (OR = 0.45, 95% CI 0.2-0.99, p = 0.042). SLE patients with DD, ID, and II genotypes had lower paraoxonase (PON) activity and higher serum levels of MDA and neopterin versus control patients. We also detected a significant protective effect against SLE in presence of ACE I alleles and lack of angiotensin II receptor, type 1 (AGTR1) A1166C (NCBI reference SNP id: rs5186), C alleles in this study (OR = 0.31, 95% CI 0.14-0.68, P = 0.002). CONCLUSIONS Carriers of the DD genotype of ACE gene with higher serum concentrations of neopterin and MDA, and lower PON activity had a high risk to develop SLE, while ID genotype decreased the risk of disease development by 2.22 times compared to II genotype.

Abstract
OBJECTIVE This study investigates the relationship between smoking and blood parameters in the Iranian Kurdish population. METHOD The current study was conducted based on the recruitment phase of the Ravansar Non-Communicable Disease (RaNCD) cohort study. RESULTS Current smokers had higher levels of RBC count, HCT, HGB, MCV, MCH, MCHC, WBC count, and GR%, than in other groups significantly. Passive smokers had higher levels of PLT count and PCT statistically. The increasing exposure time of smoking positively affected WBC count, GR%, PLT count, PCT, and RDW in female passive smokers. In addition, heavy smokers, as well as participants with a higher duration time of smoking, had the same results for significantly lower levels of lymphocyte and monocyte and a higher level of RBC indices. CONCLUSION According to the present study, along with the current smokers, the intensity of smoking, as well as the duration time of the smoke, could have a positive correlation with blood parameters. Furthermore, passive smokers and specifically secondhand female smokers were more vulnerable to smoke.

Abstract
Protein-based nanocarriers have demonstrated good potential for cancer drug delivery. Silk sericin nano-particle is arguably one of the best in this field. In this study, we developed a surface charge reversal sericin-based nanocarrier to co-deliver resveratrol and melatonin (MR-SNC) to MCF-7 breast cancer cells as combination therapy. MR-SNC was fabricated with various sericin concentrations via flash-nanoprecipitation as a simple and reproducible method without complicated equipment. The nanoparticles were subsequently characterized for their size, charge, morphology and shape by dynamic light scattering (DLS) and scanning electron microscope (SEM). Nanocarriers chemical and conformational analysis were done by fourier transform infrared spectroscopy (FT-IR) and circular dichroism (CD) respectively. In vitro drug release was determined at different pH values (7.45, 6.5 and 6). The cellular uptake and cytotoxicity were studies using breast cancer MCF-7 cells. MR-SNC fabricated with the lowest sericin concentration (0.1%), showed a desirable 127 nm size, with a net negative charge at physiological pH. Sericin structure was preserved entirely in the form of nano-particles. Among the three pH values we applied, the maximum in vitro drug release was at pH 6, 6.5, and 7.4, respectively. This pH dependency showed the charge reversal property of our smart nanocarrier via changing the surface charge from negative to positive in mildly acidic pH, destructing the electrostatic interactions between sericin surface amino acids. Cell viability studies demonstrated the significant toxicity of MR-SNC in MCF-7 cells at all pH values after 48 h, suggesting a synergistic effect of combination therapy with the two antioxidants. The efficient cellular uptake of MR-SNC, DNA fragmentation and chromatin condensation was found at pH 6. Nutshell, our result indicated proficient release of the entrapped drug combination from MR-SNC in an acidic environment leading to cell apoptosis. This work introduces a smart pH-responsive nano-platform for anti-breast cancer drug delivery.

Abstract
Purpose CD44 plays a pivotal role through tumorigenesis by regulating cancer cell metastasis, stemness, and chemosensitivity and is considered a promising therapeutic target for human cancers, including colorectal cancer (CRC). Therefore, the present research aimed to examine the simultaneous therapeutic effect of CD44 silencing and 5-fluorouracil (5-FU) on in vitro tumorigenesis of CRC cells. Methods CD44 expression was initially evaluated in TCGA datasets and CRC tissues. Furthermore, functional analysis was performed on HT-29 CRC cells overexpressing CD44. The cells were transfected with CD44 siRNA and then treated with 5-FU. Consequently, to explore the combination therapy effect on cell viability, migration, apoptosis, and chromatin fragmentation, we performed MTT assay, scratch assay, Annexin V/PI staining and DAPI staining assays, respectively. The spheroid and colony formation assays were further employed to investigate stemness features. The gene expression at protein and mRNA levels were explored using western blotting and qPCR. Results Our findings illustrated that CD44 was significantly overexpressed in CRC tissues compared to normal samples. The suppression of CD44 considerably promoted the chemosensitivity of HT-29 cells to 5-FU by apoptosis induction. Also, the combination therapy led to overexpression of apoptotic genes, including P53, caspase-3, and caspase-9, as well as downregulation of AKT1 expression. Furthermore, CD44 suppression, separately or combined with 5-FU, hindered stemness properties in HT-29 cells via downregulation of Sox2 and Nanog expression. Besides, the combination therapy remarkably downregulated MMPs and suppressed CRC cell migration. Conclusion Considering its involvement in chemosensitivity to 5-FU, CD44 could be suggested as a potential target for improving the efficiency of CRC chemotherapy.

Abstract
Background Oxidative stress is involved in the pathogenesis of preeclampsia (PE). Dysregulation of SOD1 may be involved in the pathogenesis of PE. We examined and compared the methylation level of the promoter region (PMR) of the SOD1, gene expression, and enzyme activity of superoxide dismutase (SOD) in both placenta and maternal blood in PE women. Methods A total of 140 blood samples and 40 placental tissue samples from PE and healthy pregnant controls were studied. The PMR of the SOD1 (Methylight PCR method), the expression (Real-time PCR), and its enzyme activity were investigated and compared in two groups. Results The PMR of the SOD1 gene in the placental tissue of the patients was significantly increased compared to the control group (P= 0.008); this result was accompanied by a decrease in the expression of the gene and a decrease in the activity of the SOD enzyme. Meanwhile, the PMR of the SOD1 gene did not significantly change in the blood samples of the patients (P= 0.95), while a significant decrease in the expression of SOD1 (without a significant change in the SOD activity) was observed. Conclusion The results showed significant changes in the PMR of the SOD1 gene and gene expression in placenta tissue. The results highlight the role of the placenta in complications during pregnancy and also revealed epigenetics as an important regulatory pathway in the pathogenesis of preeclampsia.

Abstract
Background This study aimed to investigate the GPx-1 gene polymorphism (rs1050450), the level of oxidative stress and antioxidant parameters, and the lipid profile in an obese Kurdish population in Sulaimani, Iraq. Methods In a case-control study,134 obese subjects and 131 normal BMI healthy individuals participated. The GPx-1 gene polymorphism was assessed by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method. The levels of biochemical and oxidative parameters were determined using photometric methods. Results The results showed that the fasting blood sugar (FBS), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) levels were significantly higher in obese subjects compared to the control group. Obese individuals had significantly lower levels of high-density lipoprotein cholesterol (HDL-C) than the controls. The GPx-1 activity and total antioxidant capacity (TAC) levels were significantly elevated in the obese group compared to the control group (P=0.006, and P<0.001, respectively). No significant difference was detected in genotype and allele frequencies of GPx-1 (rs1050450) between obese and normal BMI groups. However, the presence of the GPx-1 TT genotype enhanced the risk of obesity in females by 1.93-fold (95% CI 1.04-3.58, P=0.036). In the total population, the GPx activity increased in the presence of TT compared to CC+CT and CT genotypes. Conclusion The study indicated that obesity is linked to significantly higher levels of FBS, TG, LDL-C, TAC, and GPx activity and lower level of HDL-C. Also, we found the GPx-1 gene polymorphism was associated with the risk of obesity in females and increased the GPx activity.

Abstract
Aims The present study aimed to investigate the association between lipoprotein lipase (LPL) S447X polymorphism and type 2 diabetes mellitus (T2DM), obesity, lipid profile, and oxidative stress parameters in a population from the Kurdistan region of Iraq. Method We studied 250 adults (51% female and 49% male) aged 45-65 years in four groups, obese and normal body mass index (BMI) diabetic patients versus healthy normal BMI and obese individuals as controls. Lipid profile and oxidative stress parameters were analyzed by colorimetric assay. The LPL S447X genotypes were detected by polymerase chain reaction (PCR)-restriction fragment length polymorphism. Results We found that the obese diabetic group had higher levels of triglycerides (TG), cholesterol, and low-density lipoprotein-cholesterol, and lower level of high-density lipoprotein-cholesterol than other groups. Obese diabetic patients had higher anthropometric indices than nonobese diabetic patients, obese and normal BMI controls. The levels of TG and total oxidative status (TOS) were significantly lower and higher, respectively, in normal BMI controls than in obese controls. Obese diabetic patients had a lower level of total antioxidant capacity than nondiabetic obese controls. The level of TOS was lower in nondiabetic controls compared to the patient groups. Obese diabetic patients had the highest TOS and malondialdehyde levels. The LPL SX genotype was associated with decreased the risk of T2DM by 79% (odds ratio [OR] = 0.21; 95% confidence interval [CI]: 0.05-0.81, p = 0.03). Also, the presence of this genotype reduced the risk of obesity by 39% (OR = 0.61; 95% CI: 0.07-4.90, p = 0.6). In all individuals, the presence of the SX genotype was associated with significantly lower levels of fasting blood sugar (FBS) and TOS. Conclusion We report the influence of obesity on lipid profile in diabetic and nondiabetic individuals and the effect of LPL SX genotype on decreased risk of T2DM and reduced levels of FBS and TOS.

Abstract
Background:There is an increasing prevalence of type 2 diabetes mellitus (T2DM) worldwide. The deficiency of vitamin D is a worldwide health problem that can increase susceptibility to T2DM. Cytochrome P450 family 27 subfamily B member 1 (CYP27B1) encodes the enzyme 1α-hydroxylase in the kidney, which converts 25 (OH)-D3 to 1,25 (OH)2-D3. The CYP27B1 rs10877012 G/T polymorphism is located in the gene promoter and can influence vitamin D3 level. Objectives: This study aimed to investigate the relationship between CYP27B1 gene polymorphism and the 25 (OH)-D3 serum level and the risk of T2DM. Additionally, the effect of 25 (OH)-D3 level on metabolic parameters was investigated. Methods: We investigated 310 individuals including 205 T2DM patients and 105 healthy subjects from the city of AL-Sulaymaniyah, Kurdistan of Iraq. The CYP27B1 gene variants were identified by the polymerase chain reaction followed by digestion with HinfI restriction enzyme. Results: The mean level of 25 (OH)-D3 was 18.4±8.5 ng/mL in T2DM patients and 24.1±9.3 ng/mL in healthy controls (P<0.001). Significantly higher body mass index (BMI), HbA1c level, and fasting blood sugar concentration were detected in individuals with vitamin D insufficiency (P=0.009, P=0.001, and P=0.01, respectively) and vitamin D deficiency (P=0.025, P<0.001, and P<0.001, respectively) compared to those with a sufficient level of vitamin D. The T allele frequency of CYP27B1 was 38.1% in controls and 40.2% in patients (P=0.6). In the presence of the GT genotype, a significantly lower level of 25 (OH)-D3 was obtained compared to the GG genotype (P=0.02) among the patients. Conclusion: We found that the CYP27B1 rs10877012 polymorphism was not a risk factor for T2DM but it affected the level of 25 (OH)-D3 in diabetic patients and vitamin D deficiency and insufficiency increased the values of BMI, HbA1c, and FBS as the metabolic parameters involved in the development of T2DM.

Abstract
Background: Obesity is defined as excessive fat accumulation in the adipose tissue and peripheral organs. The Kelch-like ECH-associated protein 1 (Keap1) is involved in cellular protection in obesity. Objectives: The objectives of this study were to detect the association of Keap1 rs11085735 variants with the risk of obesity in relation to anthropometric parameters and lipid profile in a population from the Kurdistan of Iraq. Methods: A total of 265 volunteers (134 females and 131 males) were randomly selected. According to the body mass index (BMI), individuals were divided into subjects with normal BMI (131 healthy individuals) and obese subjects (134 obese volunteers). Anthropometry and lipid profile parameters were measured in these volunteers and Keap1 rs11085735 variants were identified by the polymerase chain reaction (PCR) followed by digestion with HinfI restriction enzyme. Results: Triglycerides and low-density lipoprotein cholesterol (LDL-C) serum levels were significantly higher (P<0.001) in the obese group compared to the control group. The serum level of high-density lipoprotein cholesterol (HDL-C) was significantly lower (P=0.02) in the obese individuals than in the controls. Moreover, the waist, hip, and wrist circumferences and the waist to hip ratio in obese individuals were significantly higher than in controls (P<0.001). The frequency of Keap1 AA genotype was 1.5% in the obese group and 0% in the controls (P=0.36). The frequency of A allele was 4.9% and 3.1% in obese subjects and controls, respectively (P=0.28). Considering all individuals, carriers of AA genotype of Keap1 had significantly higher BMI and waist and hip circumferences compared to the carriers of AC and CC genotypes. Conclusion: The present study found abnormal lipid profile among obese individuals compared to individuals with normal BMI. Our findings indicated that the presence of Keap1 polymorphism influenced the anthropometric parameters, and the carriers of AA genotype of Keap1 had significantly higher BMI and waist and hip circumferences compared to the carriers of AC and CC genotypes.

Abstract
BACKGROUND The incidence of metabolic heart diseases has increased significantly in Middle Eastern countries such as Iran. The present study aimed to investigate the association between monocyte percentage to high-density cholesterol ratio (MHR), lymphocyte percentage to high-density cholesterol ratio (LHR), and lymphocyte to monocyte percentage ratio (LMR) and cardiometabolic diseases in a Kurdish population in the west of Iran. METHODS This study recruited 9803 individuals, 4728 (48.2%) were male and 5084 (51.8%) were female from Ravansar, Iran. All biomarkers were analyzed by the standard methods. RESULTS The prevalence of cardiometabolic diseases was higher in overweight/obese participants and increased with age. MHR and LHR increased significantly in cardiometabolic individuals compared with healthy controls. Individuals in the fourth quartiles of LHR and MHR had higher odds ratio (ORs) for metabolic syndrome (MetS) and diabetes mellitus (DM) than the first quartiles. The LMR had a statistical association with non-alcoholic fatty liver disease (NAFLD) ORs and FLI. Besides, all these associations were stronger for females, and increased physical activity decreased inflammatory biomarkers. CONCLUSION The present study showed MHR and LHR had significant associations with ORs of MetS and DM. Also, MHR and LHR had a significant positive correlation with cardiometabolic risk factors. The LMR only had a statistical association with NAFLD and fatty liver index (FLI). Besides, the strong correlation between inflammatory biomarkers and cardiometabolic risk factors in females might be relevant to higher fat accumulation and metabolic inflammation background, and lower physical activity.

Abstract
Prostate cancer (PCa) pathology has been linked to vitamin D, vitamin D receptors (VDRs), and vitamin D binding proteins (VDBPs). We sought to investigate the association between VDR rs2228570 and rs1544410 as well as VDBP rs7041 polymorphisms and serum 25-hydroxyvitamin D (25(OH)-vitamin D) levels in PCa patients. Blood samples were collected from 111 PCa patients and 150 age-matched healthy volunteers. The VDR rs2228570 T/C, rs1544410 G/A, and VDBP rs7041 T/G genotypes were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). 25(OH)-vitamin D and PSA (Total and Free) serum levels were measured. The frequencies of VDBP genotypes T/G vs. T/T (56.5% vs. 44.5%, p = 0.01) according to the dominant model T/G + G/G vs. T/T (84.3% vs. 71.5%, p = 0.01) were significantly higher in PCa patients when compared to control group and considerably increased the risk of disease by 2.29, 1.44, and 2.13 folds respectively. Interestingly, the results demonstrated that PCa patients with the dominant model (T/G + G/G vs. T/T) of VDBP had significantly lower serum levels of vitamin D and higher serum levels of total and free PSA in comparison to the controls. Furthermore, when compared to controls, PCa patients with the dominant model T allele (T/G + G/G vs. TT) of VDBP had significantly higher vitamin D, total PSA, and free PSA concentrations. Serum levels of 25(OH)-vitamin D and rs7041 T/G polymorphism of the VDBP gene could be potential risk factors for PCa.

Abstract
BACKGROUND Since the first official report of SARS-CoV-2 infection in Iran on 19 February 2020, our country has been one of the worst affected countries by the COVID-19 epidemic in the Middle East. In addition to demographic and clinical characteristics, the number of hospitalized cases and deaths is an important factor for evidence-based decision-making and disease control and preparing the healthcare system to face the future challenges of COVID-19. Therefore, this cohort study was conducted to determine the demographics, clinical characteristics, and outcomes of hospitalized COVID-19 patients in Kermanshah Province, west of Iran. METHODS This multicenter retrospective cohort study included all suspected, probable, and confirmed cases of COVID-19 hospitalized in Kermanshah Province, Iran during the first year of the COVID-19 pandemic. Demographics, clinical characteristics, outcomes and other additional information of hospitalized patients were collected from the COVID-19 database of the Medical Care Monitoring Center (MCMC) of Kermanshah Province. RESULTS Kermanshah Province experienced three waves of COVID-19 infection considering the hospitalization and mortality rates between February 20, 2020 and February 19, 2021. A total of 27,256 patients were included in the study: 5203 (19.09%) subjects were suspected, 9136(33.52%) were probable, and 12,917 (47.39%) were confirmed COVID-19 cases. The mean age of the patients was 53.34 ± 22.74 years and 14,648 (53.74%) were male. The median length of hospital stay among COVID-19 survivors and non-survivors patients were 4 (interquartile range [IQR] 1-6) and 4 (IQR 1-8) days, respectively. Among patients with COVID-19, 2646 (9.71%) died during hospitalization. A multivariable logistic regression revealed that odds of death among patients ≥ 85 years was significantly greater than among patients < 15 years (adjusted odds ratio [aOR] 4.79, 95% confidence interval [CI] = 3.43-6.71, p≤ 0.001). Patients with one (aOR 1.38, 95% CI 1.21-1.59, p = 0.04), two (aOR 1.56, 95% CI 1.27-1.92, p = 0.001) or more (aOR 1.50, 95% CI 1.04-2.17, p = 0.03) comorbidities had higher odds of in-hospital death compared to those without comorbidities. The male sex (aOR 1.20, 95% CI 1.07- 1.35, p = 0.002), ICU admission (aOR 4.35, 95% CI 3.80-4.97, p < 0.001), intubation (aOR 11.09, 95% CI 9.58-12.84, p < 0.001), respiratory distress (aOR 1.40, 95% CI 1.22-1.61, p < 0.001), loss of consciousness (aOR 1.81, 95% CI 1.45-2.25, p < 0.001), anorexia (aOR 1.36, 95% CI 1.09-1.70, p = 0.006) and peripheral oxygen saturation (SpO2) < 93(aOR 2.72, 95% CI 2.34-3.16, p < 0.001) on admission were associated with increased risk of death in patients with SARS-CoV-2 infection. Having cough (aOR 0.82, 95% CI 0.72-0.93, p = 0.003) and headache (aOR 0.70, 95% CI 0.50-0.97, p = 0.03) decreased the odds of death. CONCLUSION The mortality rate of the patients admitted to the general wards and ICU can be a guide for allocating resources and making appropriate plans to provide better medical interventions during the COVID-19 pandemic. Several risk factors are associated with the in-hospital mortality of COVID-19, including advanced age, male sex, ICU admission, intubation, having comorbidity, SpO2 < 93, respiratory distress, loss of consciousness, headache, anorexia, and cough. These risk factors could help clinicians identify patients at high risk for death.

Abstract
Abstract
Background
Preeclampsia (PE) is one of the complications of pregnancy. The pathogenesis of PE has not been completely understood. The aims of the present study were to investigate the role of Keap1 (rs11085735) variants and the methylation status of long non-coding RNA (lncRNA) MEG3 in the risk of PE.
Methods
In a case–control study, 150 pregnant women, including 75 PE patients and 75 healthy pregnant women recruited from Western Iran with Kurdish ethnic background, were studied for Keap1 variants using polymerase chain reaction‐restriction fragment length polymorphism (PCR-RFLP). The methylation status of lncRNA MEG3 was investigated using methylation-specific PCR (MSP) among 50 preeclamptic patients and 50 controls.
Results
The frequency of Keap1 A allele was significantly lower (5.3%) in preeclamptic patients compared to controls (12.7%, p = 0.024). The frequencies of hemimethylated (UM) and full methylated (MM) lncRNA MEG3 were 94 and 6% (p = 0.04), respectively, in all patients, 86.4, and 13.6% (p = 0.04), respectively, in patients with severe preeclampsia and 98 and 0% in controls. The frequency of full methylated lncRNA MEG3 was 14.3% in early-onset preeclampsia and 2.8% in late-onset preeclampsia (p = 0.12). Patients with PE had significantly higher levels of liver biomarkers (including ALT, AST, ALP, and total bilirubin) and lower PLT counts compared to healthy pregnant women.
Conclusion
The present study suggests the presence of hypermethylation status of lncRNA MEG3 in preeclampsia that might contribute to the pathogenesis and development of preeclampsia. Also, Keap1 rs11085735 polymorphism might be involved in the risk of preeclampsia.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters cells through angiotensin converting enzyme 2 (ACE2), which expression of its gene increases during pregnancy that is resulted in an enhanced level of the ACE2 enzyme. It might enhance the risk of SARS-CoV-2 infection and its complications in the pregnant women. Although, pregnancy hypertensive disorders and severe infection with SARS-CoV-2 are correlated with high comorbidity, these two entities should be discriminated from each other. Also, there is a concern about the risk of preeclampsia and consequently severe coronavirus disease 2019 (COVID-19) development in the pregnant women. So, to answer these questions, in the present review the literature was surveyed. It seems there is higher severity of COVID-19 among pregnant women than non-pregnant women and more adverse pregnancy outcomes among pregnant women infected with SARS-CoV-2. In addition, an association between COVID-19 with preeclampsia and the role of preeclampsia and gestational hypertension as risk factors for SARS-CoV-2 infection and its complications is suggested. However, infection of the placenta and the SARS-CoV-2 vertical transmission is rare. Various mechanisms could explain the role of COVID-19 in the risk of preeclampsia and association between preeclampsia and COVID-19. Suggested mechanisms are included decreased ACE2 activity and imbalance between Ang II and Ang-(1-7) in preeclampsia, association of both of severe forms of COVID-19 and pregnancy hypertensive disorders with comorbidity, and interaction between immune system, inflammatory cytokines and the renin angiotensin aldosterone system and its contribution to the hypertension pathogenesis. It is concluded that preeclampsia and gestational hypertension might be risk factors for SARS-CoV-2 infection and its complications.

Abstract
Preeclampsia as a multifactor hypertensive disorder of pregnancy is associated with enhanced placental oxidative stress. The Keap1-Nrf2 pathway protects cells against oxidative stress. We examined the possible association between the Nrf2 variants in relation to oxidative stress parameters with the risk of preeclampsia. We studied 150 preeclampsia women and 150 women with a normal pregnancy to find the frequency of Nrf2 rs6721961 genotypes using the PCR-RFLP method. Also, an association between the Nrf2 genotypes with the levels of malondialdehyde (MDA) and total antioxidant capacity (TAC) was analyzed. Significantly lower TAC and higher MDA levels were found in preeclampsia patients compared to controls (P<0.0001). For the first time, we report an association between the Nrf2 rs6721961 polymorphism and preeclampsia risk. The present study indicated that the GT genotype and the T allele of the Nrf2 rs6721961 increased the risk of preeclampsia by 2.81 and 2.39 times, respectively. Also, the Nrf2 TT genotype was associated with a 3.9-fold increased risk of early-onset preeclampsia. We detected a positive association between the levels of body mass index, MDA, and the Nrf2 polymorphism with the risk of preeclampsia and a negative correlation between the level of TAC with the preeclampsia risk. Also, an association between the rs6721961 TT genotype with higher serum MDA levels was found. Our study suggests oxidative stress is involved in the pathogenesis of preeclampsia and the Nrf2 rs6721961 polymorphism through alteration in the levels of oxidative stress parameters might increase the risk of preeclampsia and early-onset preeclampsia.

Abstract
Introduction Chronic hyperglycemia activates the inflammatory pathways and oxidative stress mechanisms with consequent damage to nerve tissue and retina. The Keap1‐Nrf2 pathway acts as one of the most important antioxidant pathways of the organism. Variants of Keap1 could affect susceptibility to diabetes and its complications. Methods In a case‐control study, 400 individuals included type 2 diabetes mellitus (T2DM) patients without complication, with neuropathy, with retinopathy, and healthy individuals were investigated. The levels of glutathione (GSH), glutathione peroxidase (GPx), malondialdehyde (MDA), and total antioxidant capacity (TAC) were measured using chemical methods. Using the PCR‐RFLP method, the Keap1 (rs11085735) variants were identified. Results Neuropathic patients had significantly lower levels of GSH, GPx, and TAC and higher levels of total oxidative status (TOS), MDA, and oxidative stress index (OSI) compared to T2DM patients without complication and controls. Lower levels of GSH and GPx and a higher level of MDA were observed in patients with retinopathy compared with controls. Obesity was associated with significantly lower GPx activity and higher TOS. A significantly higher Keap1 AA genotype was found in patients with neuropathy than T2DM without complication and controls. The presence of Keap1 AA genotype correlated with lower GPx activity compared to CC genotype. Conclusions Our study suggests the role of reduced antioxidant system and Keap1 variants in the pathogenesis of T2DM and its complications of neuropathy and retinopathy and also obesity in enhanced oxidative stress. Monitoring oxidative stress parameters in diabetic patients, especially those with complication and their treatment with antioxidants is suggested.

Abstract
AIMS The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to the ACE2 component of the renin-angiotensin aldosterone system (RAAS) and infects the human cells. The aims of the present review were to look at the role and alteration of the RAAS components in SARS-CoV-2 infection, therapeutic approaches, and clinical trials in this field. METHODS We surveyed the literature (PubMed, Web of Science, and Scopus) till August 18, 2021, and 59 published papers regarding the components of the RAAS and their role and alterations in SARS-CoV-2 infection along with various COVID-19 therapies based on the RASS components were included in the study. RESULTS ACE inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor inhibitors are agents that significantly enhance the ACE2 and Ang-(1-7) levels, which can be suggestive for their role as therapeutics against SARS-CoV-2 infection. Beta-adrenergic blockers, which negatively regulate renin release from juxtaglomerular cells, and vitamin D, as a regulator of the RAAS and renin expression, are proposed therapeutics in the treatment of COVID-19. Some antihyperglycemic agents could be potentially protective against COVID-19-induced lung injury. Also, the inhibition of the Janus kinase/signal transducer and activator of the transcription pathway as a potential treatment for COVID-19 has been suggested. Finally, resveratrol, an antioxidant that can suppress Ang II, has been suggested as an adjunct to other therapies. CONCLUSION Regarding the suggested potential therapies for COVID-19, there are many clinical trials whose results might change the treatment strategies of SARS-CoV-2 infection. So, the results of well-organized clinical trials on the efficacy and safety of the mentioned agents in the treatment of COVID-19 will be useful in the management and therapy of the disease.

Abstract
We surveyed published papers and an international sickle cell disease (SCD) registry to detect susceptibility and clinical course of coronavirus disease 2019 (COVID-19) in SCD patients. COVID-19 presentation was mild in children and moderate in many SCD adults. Regarding increased comorbidities with age, it seems severe COVID-19 to be more common in older SCD patients. Although the overall outcome of COVID-19 was favorable in SCD children, a high rate of pediatric intensive care unit admission should be considered in managing these patients. To explain COVID-19 outcome in SCD patients, the possible benefits of hydroxyurea therapy could be considered. The obtained results should be interpreted, considering low cases from sub-Saharan people, younger age of SCD patients compared to general population, a bias toward registry of the more severe form of disease, the effect of pre-existing comorbidities with multisystem organ damage, and the role of health socio-economic determinants.

Abstract
Objectives Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the COVID-19 pandemic. The majority of patients experience asymptomatic to mild self-limited disease, but some cases progress to respiratory and multi-organ failure. However, so far, no approved antiviral therapy has been available for treatment of COVID-19. Sofosbuvir/velpatasvir (SOF/VEL) is an approved anti-HCV drug that is capable of suppressing other families of positive-sense RNA viruses with conserved polymerase and may be effective against SARS-CoV-2. This study was conducted to evaluate the efficacy of the SOF/VEL combination in addition to the national standard of care versus the national standard of care alone (hydroxychloroquine and lopinavir/ritonavir as well as supportive care) in patients with moderate to severe COVID-19 infection. Methods This single-centre, randomized, open-labelled, prospective clinical trial was done in patients with moderate to severe COVID-19 admitted to Farabi Hospital in Kermanshah Province, Iran. Eligible patients were randomly assigned in a 1:1 ratio to the SOF/VEL arm (SOF/VEL plus the national standard of care) or the control arm (the national standard of care alone). The main outcome of the study was the mortality on Day 28 after randomization. Secondary outcomes were time from the start of medication to clinical improvement, hospital length of stay, need for mechanical ventilation, duration of mechanical ventilation and conversion of RT–PCR results from positive to negative from the time of randomization to discharge. Adverse events were evaluated in all patients who started their assigned treatment. Results Between 11 April and 8 June 2020, 80 patients were recruited and randomly assigned into the SOF/VEL (n = 40) and control (n = 40) arms. The primary outcome was not significantly different between the two arms (P = 1.00). Secondary outcomes, including time to clinical improvement, hospital length of stay, need for mechanical ventilation, duration of mechanical ventilation and RT–PCR conversion, were not significantly different between arms either (P > 0.05). SOF/VEL treatment and the national standard of care were tolerated similarly. Conclusions Although treatment with SOF/VEL was safe, adding SOF/VEL to the standard of care did not improve the clinical status or reduce mortality in patients with moderate to severe COVID-19. However, larger randomized clinical trials including more parameters are needed for accurate estimation of the efficacy of SOF/VEL.

Abstract
Introduction Sickle cell disease (SCD) patients are susceptible to the development of vitamin D deficiency (VDD). Vitamin D through binding to vitamin D receptor (VDR) exerts its function and affects gene transcription in target tissues. VDR gene variants affect bone mineral density. Methods In a case‐control study, 101 SCD patients including 61 sickle cell anemia (SCA), 39 S/β‐thalassemia, and 1 HbS/HbD (SD) along with 110 healthy individuals from Kurdistan of Iraq were studied. The lipid profile, vitamin D level, FokI, and TaqI variants of VDR and group‐specific component (GC) were detected using the standard enzymatic method, the immunodiagnostic systems limited EIA kit and PCR‐RFLP methods, respectively. Results Around 93% and 82% of SCA and S/β‐thalassemia patients, respectively, had VDD compared to 83% of healthy individuals. Severe VDD (<10 ng/ml) was detected in 78.7% of patients with HbSS. Plasma levels of total cholesterol, HDL‐C, and LDL‐C in SCD patients were significantly lower compared to controls. Vitamin D levels were negatively correlated to TG and positively correlated to total cholesterol and HDL‐C. The frequencies of the C allele of FokI were 81.7% (p = 0.003), 80.3% (p = 0.034), and 84.6% (p = 0.011) in all SCD, SCA, and S/β‐thalassemia patients, respectively, compared to 69.1% in controls. However, no significant difference was detected comparing the frequencies of VDR TaqI and GC polymorphisms between SCD patients and controls. Conclusion In the present study, we found hypocholesterolemia, high prevalence of VDR FokI C allele, and low vitamin D levels among children and adults with SCD from Kurdistan of Iraq.

Abstract
Caveolin-1(cav-1) is overexpressed in prostate cancer (PC) and is associated with progression of the disease. We investigated the effects of CAV1-T29107A and endothelial nitric oxide synthase (eNOS) G894T polymorphisms on the serum levels of testosterone, NO and prostate-specific antigen (PSA) in patients with PC. We genotyped cav-1 and eNOS genes in 112 PC patients and 150 healthy controls by PCR-RFLP. Serum levels of NO 2 - and NO 3 - were measured using spectrophotometry, and serum levels of testosterone and PSA were measured by ELISA. The frequencies of CAV1 genotypes A/T vs. A/A according to the dominant model AT + TT vs. AA genotype and T allele were significantly higher in PC patients in comparison with the control group and considerably increased the risk of disease by 2.19-, 1.44- and 1.6-fold, respectively. AT + TT genotypes were associated significantly with the increased risk of PC in those with smoking or diabetes by 3.08-fold (P = .004). Individuals carrying concurrently the T allele of CAV1 A29107T and the T allele of eNOS G894T genes had a significantly increased risk of PC by 2.52-fold (P = .009). We did not find any significant relationship between eNOS G894T genotypes and alleles with susceptibility to PC. Our results highlighted the significance of CAV1-T29107A SNP but not (eNOS) G894T in the susceptibility to PC in our the population that we have studied.

Abstract
As a promising strategy in overcoming drug resistance, the nano drug co-delivery system (NDCDS) can transport two or more drugs into the cell. In this study, we sought to compare the dual and single drug-delivery system, to deliver the optimal dose of Resveratrol (RES) and Tretinoin (TTN) into the in vitro matured oocyte and morula-compact stage embryonic cells. The formation of single (RES/TTN) and dual-drug (RES + TTN)-SLN were confirmed by Uv-vis spectrophotometery, dynamic light scattering (DLS), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) technologies. In two experiments, the oocytes/presumptive zygotes were cultured under various concentrations of the single (RES/TTN) and dual-drug (RES + TTN)-SLN. In vitro toxicity studies, including nuclear staining (Aceto-orcein and Hoechst 33342), H2DCFDA fluorescent staining, chemiluminescence assay, and quantitative reverse transcription-PCR (qRT-PCR) techniques, indicated an excellent oocyte/embryo internalization of RES and TTN. Moreover, when oocytes/embryos were treated with the lowest concentration of RES + TTN-SLN, antioxidants-related genes were upregulated, apoptotic-related genes were downregulated, and intra/extracellular ROS production was reduced. In vitro cytotoxicity studies also demonstrated that single/dual-encapsulation of RES or TTN were safe even at the highest concentration (10 and 5 μM) compared to the control group. To sum it up, both delivery systems of RES and TTN by SLN (dual or single encapsulation) can deliver the optimal dose of RES and TTN into the oocyte/embryo. Where the dual-delivery of RES and TTN even at the lowest concentration (0.25 μM + 0.1 μm) showed a synergistic anti-oxidative effect in oocyte/embryo with a better inhibition of intra/extra-cellular ROS production by an enhanced/controlled intracellular penetration.

Abstract
Background Reactive oxygen species (ROS) play a crucial role in etiology of DNA fragmentation and lipid peroxi-
dation in sperm, leading to infertility in men. The silent information regulators SIRT1 and SIRT3 are members of the
sirtuins protein family known to be involved in cancer genetics, aging and oxidative stress responses. The aim ofthis
study is to determine the correlation between SIRT1 and SIRT3 with antioxidants, oxidative stress biomarkers, and
DNA fragmentation in the semen of asthenoteratozoospermic and normozoospermic men. Materials and Methods In this case-control study, after spermogram analysis the specimens were divided into
two groups, normozospermic (n=40) and asthenoteratozoospermic (n=40), according to World Health Organization
(WHO) standards. Sperm DNA fragmentation was evaluatedusing the sperm chromatin dispersion (SCD) test.Catalase
activity was measured using the Aebi spectrophotometeric method. Total antioxidant capacity (TAC) level and super-
oxide dismutase (SOD) activitywere measured by using commercially available colorimetric assays. Enzyme-linked
immune sorbent assay (ELISA) was used to measure SIRT1 and SIRT3 protein levels of seminal plasma. Malondial-
dehyde (MDA) level in seminal plasma was determined by high-performance liquid chromatography (HPLC). Results The asthenoteratozoospermic group had significantly lower catalase and SOD activities and TAC levels in
comparison with the normozoospermic group (P<0.001).The percentage of DNA fragmentation and MDA level in the
asthenoteratozoospermic group were remarkably higher than in the normozoospermic group. The SIRT1 and SIRT3
protein levels in seminal plasmawere remarkably lower in asthenoteratozoospermic group than the normozoospermic
group (P<0.001). Conclusion The results of this study suggest that SIRT1 and SIRT3 protein levels are negatively correlated with
oxidative stress and DNA fragmentation in semen. The low levels of SIRT1 and SIRT3 in asthenoteratozoospermic
men may lead to an increase in oxidative stress, DNA fragmentation, and lipid peroxidation that eventually result in
immotile and immature spermatozoa (asthenoteratozoospermia).

Abstract
BACKGROUND AND PURPOSE In recent years, the interest in chitosan nanoparticles has increased due to their application, especially in drug delivery. The main aim of this work was to find a suitable method for simulating pharmaceutical nanoparticles with computational fluid dynamics (CFD) modeling and use it for understanding the process of nanoparticle formation in different types of microchannels. EXPERIMENTAL APPROACH Active and passive microchannels were compared to find the advantages and disadvantages of each system. Twenty-eight experiments were done on microchannels to quantify the effect of 4 parameters and their interactions on the size and polydispersity index (PDI) of nanoparticles. CFD was implemented by coupling reactive kinetics and the population balance method to simulate the synthesis of chitosan/tripolyphosphate nanoparticles in the microchannel. FINDINGS/RESULTS The passive microchannel had the best performance for nanoparticle production. The most uniform microspheres and the narrowest standard deviation (124.3 nm, PDI = 0.112) were achieved using passive microchannel. Compared to the active microchannel, the size and PDI of the nanoparticles were 28.7% and 70.5% higher for active microchannels, and 55.43% and 105.3% higher for simple microchannels, respectively. Experimental results confirmed the validity of CFD modeling. The growth and nucleation rates were determined using the reaction equation of chitosan and tripolyphosphate. CONCLUSION AND IMPLICATIONS CFD modeling by the proposed method can play an important role in the prediction of the size and PDI of chitosan/tripolyphosphate nanoparticles in the same condition and provide a new perspective for studying the production of nanoparticles by numerical methods.

Abstract
Background & Objective: Breast cancer (BC) is known to be the most prevalent cancer among women. One-carbon metabolism disturbance might play an important role in the etiology of BC. The present study aimed to investigate the thymidylate synthase (TYMS), 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR), and methionine synthase reductase (MTRR) variants as good candidates for studying the role of genetic variants of folate metabolizing enzymes in the risk of BC. Methods: The present case-control study includes 100 BC patients and 141 healthy females. The TYMS 2R/3R (rs34743033), MTR c.2756A>G (rs1805087), and MTRR c.66A>G (rs1801394) variants were detected by polymerase chain reaction (PCR), PCR-restriction fragment length polymorphism (RFLP), and a designed amplification-refractory mutation system (ARMS) method, respectively. Results: The 3R allele of TYMS enhanced the risk of BC by 2.84-fold (P<0.001). In the presence of TYMS 3R/3R, compared to TYMS 2R/3R, there was a trend toward enhancing the risk of metastasis by 4.15-fold (95% CI: 0.96-17.85, P=0.055). The frequencies of MTR c.2756A>G and MTRR c.66A>G variants were not significantly different among patients and controls. Conclusion: We observed that the TYMS 3R is a risk allele for susceptibility to BC and this allele may increase the risk of metastasis in BC patients. .

Abstract
OBJECTIVE The relationship between RBC indices and metabolic diseases remains unclear. The association between anemia and obesity is also controversial. The present study aimed to investigate the relationship between RBC indices and metabolic diseases caused by obesity and evaluate the effect of body mass index (BMI) on RBC indices on the Ravansar cohort data. METHOD For the purpose of this study, 9826 participants aged 35-65 years (5158 females and 4668 males) were recruited in the analyses. A quadratic prediction fit plot investigated the association between RBC indices with BMI and lipid profile. The odds ratio of obesity-related diseases in each quartile category of RBC indices and anemia was estimated using multivariable logistic regression models. RESULTS Subjects in the fourth quartiles of RBC count, hematocrit (HCT), hemoglobin (HGB), and red cell distribution width (RDW) had a higher risk for obesity-related diseases compared to the first quartiles. However, individuals with the mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) in fourth quartiles had lower ORs of obesity-related diseases. While BMI reduced the effect of RBC count, HCT, HGB, and RDW on the incidence risk of obesity-related disease, it increased the impact of MCV, MCH, and MCHC. There was a negative association between BMI and RBC indices except for RDW. The BMI effect on RBC indices was different in normal and obese individuals. BMI in mild anemia lowered the risk of metabolic diseases, but it increased the risk of metabolic diseases for moderate anemia. CONCLUSION A higher risk of obesity-related diseases was observed in the fourth quartiles of RBC count, HCT, HGB, and RDW compared to the first quartiles. However, the incidence risk was lower for MCV, MCH, and MCHC. BMI plays an anemia-type dependent role in the relationship. Consideration should be given to the type of anemia in the relationship between BMI and anemia.

Abstract
Objective: To find whether the gene variants and haplotypes of cytochrome (CYP) 27B1 (1α-hydroxylase), group-specific component (GC) that is a vitamin D binding protein, vitamin D receptor (VDR), peroxisome proliferator-activated receptor γ (PPARγ) and retinoid-X receptor (RXR) affect the risk of preeclampsia. Methods: In a case-control study 100 women with preeclampsia and 100 healthy pregnant women were investigated for gene variants and haplotypes of vitamin D biosynthesis, transport, and function using the polymerase chain reaction-restriction fragment length polymorphism method. Results: The frequency of gene variants of PPARγ Pro12Ala and RXR -α (A/G, rs749759) were not significantly different comparing patients and controls. The TT genotype of CYP 27B1 (G > T) was associated with 2.2-fold (95% CI 1.04-4.7, p = 0.039) increased risk of early-onset preeclampsia. Also, the TT genotype of GC rs7041 (T > G) increased the risk of preeclampsia [OR = 2.13 (95% CI 1.09-4.17, p = 0.027)]. The VDR ApaI GT genotype elevated susceptibility to preeclampsia (OR = 2.55, p = 0.04). Further, the presence of VDR ApaI GT+TT genotype was associated with higher levels of body mass index, and systolic blood pressure, and lower level of 25 (OH)-D3. In the presence of haplotype CYP T, VDR T, and RXR A (TTA) compared to haplotype GTG the risk of preeclampsia was 6.71-fold (p = 0.044). Conclusions: The present study indicated an association between the CYP 27B1, GC, and VDR ApaI variants with the risk of preeclampsia. Also, the variants of the latter polymorphism influenced BMI, blood pressure, and vitamin D levels.

Abstract
The dynamics of water molecules inside an Aquaporin channel, embedded within a stochastically fluctuating membrane, was modeled by means of the application of the molecular dynamics (MD) simulation method. We considered the effect of the existence and nonexistence of an external electric field, either constant or oscillating, on the stability of the channel. It was observed that the permeation of water molecules through the channel was increased when the channel was exposed to a constant electric field of strength -0.2 mV nm-1. Moreover, oscillating electric fields of 5 and 10 GHz frequencies, which is the range of field frequency generally present in our daily life, were applied to the channel, showing not significant effects on the stability of the channel and its important parts. In addition, we investigated the influence of the application of electric fields on the water molecule ordinations in the channels, and the results showed that the water molecule orientations were changed in response to the applied field.

Abstract
Matrix metalloproteinases (MMPs) are a group of zinc dependent enzymes that are involved in tumor cell invasion and metastasis. The role of MMP-2 and -9 genetic polymorphism in different malignancies has been the subject of numerous studies. The present research has attempted to discover any positive correlation between MMP-2 and MMP-9 SNPs and prostate cancer (PCa) in patients with a history of either diabetes or smoking habits. 112 PCa-patients and 150 unrelated healthy-controls that matched for age and sex were selected for present case-control study. MMP-2 -1575G/A and MMP-9 -1562 C/T polymorphisms detected by PCR-RFLP, serum tissue inhibitors of metalloproteinases (TIMP-1 and TIMP-2), testosterone, prostate-specific antigen (PSA), free-prostate-specific-antigen (fPSA), and fPSA/PSA levels were detected by ELISA and enzyme assay, respectively. MMP-2 and MMP-9 activities were measured by gelatin-zymography. Covariates were considered as age, status of cigarette smoking, and a possible history of diabetes mellitus (DM). The frequency of -1575 MMP-2 A/A + A/G and -1562 MMP-9 C/T + T/T genotypes were higher in PCa-patients with DM (74.3%,p = 0.003) and with smoking habits (72.5%,p = 0.005). These genotypes were associated with the increased risk of prostate cancer in smokers (3.52-folds) and in individuals with history of DM (4.34-folds). A significant positive association was found between level of TIMPs (TIMP -1 and TIMP-2) and BMI in PCa-patients and also between testosterone levels and MMP-9 activity in healthy control subjects. For the first time, this study demonstrated that activities of MMP-2 -1575G/A and MMP-9 -1562C/T variants in association with smoking and diabetes are considered significant risk factors for PCa.

Abstract
INTRODUCTION It is necessary to establish hematological reference intervals (RIs) in each population to improve disease management and healthcare quality. This study aimed to establish age- and sex-specific hematological RIs in a healthy adult Kurdish population and evaluate the influence of select lifestyle factors. METHODS Hematological parameters were studied in 6518 individuals (3006 females, 3512 males) from Ravansar Non-Communicable Disease (RaNCD) cohort study. Hematological parameters were measured by Beckman Coulter HmX Analyzer. After combined application of exclusion criteria and statistical outlier removal, RIs for all partitions were calculated using nonparametric methods. RESULTS The present study established hematological RIs for 14 parameters in a healthy adult Iranian population. Reference values for some analytes demonstrated significant age- and sex-specific differences and were slightly different when compared to RIs determined in other populations. Furthermore, the current smokers had higher levels of white blood cells (WBCs), red blood cells (RBCs), hemoglobin, hematocrit, mean corpuscular hemoglobin (MCH), and mean corpuscular volume than ex- and nonsmokers. Also, in the presence of high physical activity, elevated levels of RBC, hemoglobin, hematocrit, monocytes, and MCH were observed, as well as lower WBC levels. Further, a significant positive association was observed between body mass index (BMI) and WBC, red cell distribution width, and plateletcrit levels. CONCLUSION Our study suggests hematological parameters are influenced by age, sex, and lifestyle factors such as physical activity and BMI. Additionally, discrepancies when compared to other population studies suggest that ethnic-specific differences need to be considered when establishing RIs for hematological parameters.

Abstract
BACKGROUND Infection with coronavirus disease 2019 (COVID-19) could be complicated with coagulopathy and high risk of thromboembolic events. AIMS The main aim of the present study was to find the coagulation profile of intensive care unit (ICU) admitted patients with COVID-19 from Kermanshah, Islamic Republic of Iran. METHODS Coagulation parameters were analyzed using appropriate methods in 74 patients (24 patients aged <60 years and 50 patients ≥60 years) and were compared with 35 survivors (severe COVID-19) and 39 non-survivors (severe COVID-19) historically admitted to the ICU. RESULTS Forty-two percent of patients had abnormal prothrombin time and international normalized ratio. The rates of mortality and comorbidity in patients aged ≥ 60 years were 73.7% and 78.4% compared to 26.3% and 21.6%, respectively, in patients aged < 60 years. CONCLUSION We found an abnormal pattern of coagulation parameters and association of advanced age and comorbidities with a high rate of mortality in severe COVID-19 patients, which should be taken into consideration in their hospital management.

Abstract
Objective The current research was conducted to study the association between the SNP309 and del1518 polymorphisms with the breast cancer in the patients with the Kurdish ethnic background from western Iran. Also, a systematic review of the relevant case‐control studies on the MDM2 polymorphisms in the patients with breast cancer was performed. Methodology Two mL of peripheral blood was taken from 100 patients with breast cancer and 100 healthy individuals. The frequencies of MDM2 SNP309 and del1518 genotypes and alleles were determined using the PCR‐RFLP and PCR methods, respectively. Results The frequency of the TT, TG, and GG of MDM2‐SNP309 genotypes in the patients was obtained as 23%, 52%, and 25%, and they were equal to 22%, 40%, and 38% in the control group, respectively. Also, considering the MDM2‐del1518 polymorphism, the frequencies of ins/ins, ins/del, and del/del genotypes were equal to 52%, 41%, and 7% in the breast cancer group and they were equal to 62, 30, and 8% in the control group, respectively. Analysis of the results indicated that the GG genotype plays a protective role for the breast cancer in the recessive model (GG vs TT + TG) of SNP309 (χ2 = 3.916, P = .048, and OR = 0.54). Conclusion Our findings revealed that the GG genotype of MDM2‐SNP309 can play a protective role in the breast cancer disease. Also, our systematic review indicated that the SNP309, SNP285, and del1518 of MDM2 gene in different populations mostly did not have a significant association with the risk of breast cancer.

Abstract
Background: There is concern about susceptibility of psoriatic patients on biologics to coronavirus disease 2019 (COVID-19) and its clinical course.Purpose: The aims of present review were to determine whether the biologic treatment of psoriasis increases the risk of SARS-CoV-2 infection and if biologics affect the clinical course of COVID-19 in these patients.Methods: We searched database of MEDLINE (PubMed) for key term of psoriasis biologic and COVID-19 until June 9, 2020 and all published 14 papers and an experience from Iran (10509 cases) related to the psoriatic patients on biologics and COVID-19 along with relevant papers were summarized. In spite of limitation in some reports, due to some of strengths that will be discussed, all papers were included in this review.Results: According to 8769 medical reports around 0.3% of psoriatic patients had COVID-19 and the rate of hospitalization was 0.1%. No death due to COVID-19 was reported among 10509 patients. Reports indicated psoriatic patients on biologics were not more susceptible to COVID-19 and the severe clinical course of disease.Conclusion: While there is not definitive controlled trial data, the available evidence suggests that patients with psoriasis without COVID-19 can continue the biologic therapy for psoriasis.

Abstract
Hemoglobinopathies are the most common single gene disorders (monogenic disorders) in the world population. Due to specific position of Iran and the presence of multi-ethnic groups in the country, there are many varieties in the molecular genetics and clinical features of hemoglobinopathies in Iran. Hemoglobinopathies include structural variants, thalassemias, and hereditary persistence of fetal hemoglobin. In this review, we look at the common structural variants in various parts of the country along with their hematological and clinical characteristics. Also, we discuss about the burden of the thalassemias in the country, different types, complications, molecular defects and therapy.

Abstract
Gaucher disease (GD) is most frequent disorder of glycolipid storage. The glucosylceramide accumulation might lead to oxidative stress and changes in lipid profile. Regarding the main role of trace elements in hematopoiesis and oxidative stress, this study was aimed to evaluate the zinc and copper levels, three oxidative stress parameters, and lipid profile in GD. Thirty-three patients with GD along with 64 age- and sex-matched healthy controls participated in the study. The levels of zinc and copper were determined using atomic absorption/flame emission spectrophotometer. Malondialdehyde level was measured using HPLC. Total antioxidant capacity (TAC), catalase activity, and lipid profile were assessed using colorimetric methods. Data were analyzed using SPSS software version 16.0. Significant decrease in the serum levels of Zn (p < 0.001) and Cu (p < 0.001) was observed in patients with GD compared to controls. Subjects in control group showed significantly higher levels of TAC than patients with GD (p < 0.001). In contrast, plasma concentration of malondialdehyde was insignificantly higher in patients with GD than controls (p = 0.06). There was a direct correlation between TAC and hemoglobin concentration (p = 0.035; r = 0.369) in patients with GD. Furthermore, the calculated area under receiver operating characteristic curve for HDL cholesterol was equal to 0.938. The results showed that both zinc and copper levels decreased in patients with GD. Patients with GD showed decreased serum content of TAC. It was found that improving the deficiency of zinc and copper by supplementing them could be useful in management of patients with GD.

Abstract
Background & Objective To find an association between gene variants of insulin-like growth factor-1 (IGF-1) and 5,10-methylenetetrahydrofolate reductase (MTHFR) with the risk of acne vulgaris (AV). Methods In a case-control study, we investigated 150 AV patients and 148 healthy individuals (aged 18-25 years) for the IGF-1 G>A and MTHFR C677T polymorphisms, as well as the serum levels of IGF-1, insulin, and the homeostasis model assessment of insulin resistance (HOMA-IR). The serum biochemical parameters and the genotypes of IGF-1 G>A and MTHFR C677T were detected by using appropriate kits and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods, respectively. Results The frequencies of IGF-1 and the MTHFR polymorphisms were not significantly different comparing patients and controls. The serum level of IGF-1 was 179.8±72.8 µg/L in AV patients compared to 164.6±63.7 µg/L in controls (P=0.056). The serum level of insulin in female patients was significantly higher than controls. The HOMA was 3.54±5.6 in patients compared to 1.16±1.4 (P<0.001) in controls. Significantly higher levels of fasting blood sugar (FBS), total cholesterol, and low-density lipoprotein-cholesterol (LDL-C) were detected in female patients than controls. However, the level of estradiol was significantly lower in female patients than in controls. In females, the presence of the MTHFR T allele was associated with significantly higher levels of FBS and LDL-C, as well as a significantly lower level of estradiol compared to those carriers of the C allele. Conclusion We found the absence of an association between IGF-1 and MTHFR polymorphisms with the risk of AV. However, increased insulin, IGF-1, and HOMA levels in AV patients indicated the effect of insulin and insulin resistance in the risk of AV and its severity.

Abstract
Polymeric ultrafiltration (UF) membranes often used in membrane bioreactor (MBR) prone to be fouled by fouling agents. Therefore, in this paper, the antifouling characteristics of polyvinylidene fluoride (PVDF) UF membranes for wastewater treatment are improved through modifying membranes by O-carboxymethyl chitosan (OCMCS)-functionalized Fe3O4 nanoparticles (OCMCSFe3O4). The modifier agent was manufactured by the adsorption of OCMCS on Fe3O4 nanoparticles, which were synthesized via co-precipitating method. Antifouling performance of membranes was assessed by permeation tests done using activated sludge suspension as a biological foulant, then the calculation of the pure water flux recovery ratio (FRR) and fouling resistance parameters. Also, to investigate the protein rejection of membranes, permeation tests were conducted by the bovine serum albumin (BSA) solution. According to the obtained results, surface hydrophilicity of the embedded membranes was improved in the low concentrations of the modified nanoparticles. However, the high quantity of the OCMCS-Fe3O4 nanoparticles (>0.1 wt. %) in the casting solution lessened membrane performance owing to the agglomeration of the nanoparticles in the polymer matrix. Although, the 1 wt. % OCMCS-Fe3O4 membrane revealed considerably higher PWF and permeation than that of the other membranes. It was because of defects and cracks in the membranes. The 0.05 wt. % OCMCS-Fe3O4/PVDF membrane exhibited the highest FRR (95.7%) and protein rejection value (48%) and the lowest irreversible fouling resistance (Rir) value (4.2%). It is concluded that the blended membranes with modified nanoparticles resulted in a high-flux ultrafiltration membrane comparable with microfiltration membrane, while its separation properties remained similar to UF membrane.
