    Abstract Objectives: Endothelial cell (EC) apoptosis plays a critical role in the physiological and pathological vascular regression, remodeling, and angiogenesis. There are several therapeutic agents such as glucocorticoids (GCs), which could influence EC apoptosis, causing coagulation events. Due to the paradoxical effects of GCs on cellular apoptosis, the aim of the current study was to investigate the dose and time in which GCs could initiate and terminate in vitro cellular apoptosis. Materials and Methods: Dexamethasone (DEXA) was serially diluted 10-folds for 8 serial concentrations (from 1 mM to 0.1 nM) added to cultured human umbilical vein endothelial cells (HUVECs). The cytotoxic effects of DEXA on HUVEC were tested with a rapid colorimetric test using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide assay. Apoptotic assays based on quantitative polymerase chain reaction was performed for Bax and Bcl-2 genes and terminal deoxynucleotidyl transferase dUTP nick end labeling assay. Results: DEXA at the concentration of 1 µM showed significant cytotoxic effects, more intense anti-apoptotic effects in lower concentrations (1 nM to 100 nM), and anti-apoptotic effects with less intensity in higher concentrations (10 µM to 1 mM). Six hours of treatment by 1 µM of DEXA was estimated as the initial time of DEXA that could remarkably induce HUVECs apoptosis. The maximum significant increase of apoptosis was detected 24 hours after treatment with DEXA. Conclusions: Our findings suggested that GCs can influence cellular apoptosis in a dose- and time-dependent manner.

    Abstract Background and aims: Diabetes is associated with cardiovascular and metabolic disorders. Although the favorable role of physical activity and antioxidants in people's health has been reported, the simultaneous effect of HIIT and crocetin on angiogenesis in heart tissue is not well known. The aim of this study was to investigate the effect of eight weeks of intermittent aerobic training with the consumption of crocetin extract on some indicators of angiogenesis in the heart tissue of prediabetic and diabetic aged rats. Methods: In this experimental trial, 48 elderly female c57bl6 male mice with diabetes (40 mg/kg peritoneal injection) aged 14-16 weeks and weighing 30-35 gr were divided into (1) pre-diabetic (2) pre-diabetic+ groups. Aerobic exercise (3) pre-diabetic + crocetin (4) pre-diabetic + aerobic exercise + crocetin (5) diabetic (6) diabetic + aerobic exercise (7) diabetic + crocetin (8) diabetic + aerobic exercise + crocetin were divided. In order to investigate the effect of modeling on the variables, 5 healthy rats were included in the healthy control group. Groups 2, 4, 6, and 8 did interval aerobic exercise five sessions a week for eight weeks. Groups 3, 4, 7, and 8 received 30 mg/kg/day crocin by intraperitoneal injection. To analyze the data, one-way analysis of variance and Tukey's post hoc test were used in GraphPad Prism 8.3.3 software (P≥0.05). Results: The expression values of FGF-2 in the pre-diabetes group + aerobic exercise + crocetin supplement and the diabetes group + aerobic exercise + crocetin supplement were significantly higher than other groups (P≥0.05); NO gene expression values in the pre-diabetes group + aerobic exercise + crocetin supplement and diabetes group + aerobic exercise + crocetin supplement were significantly lower than other groups (P≥0.05). The insulin and glucose levels in the pre-diabetes group + aerobic exercise + crocetin supplement and the diabetes group + aerobic exercise + crocetin supplement were significantly lower than other groups (P≥0.05). Conclusion: It ...

    Abstract Coronaviruses are a group of enveloped viruses with single-stranded non-segmented positive-sense RNA genomes. In December 2019, SARS-CoV-2 appeared in China for the first time and quickly spread throughout the world. Although certain medications suggested for other afflictions tend to be potentially effective for curing the infection, there is no approved vaccination or drug available for this virus yet. Comprehension of the disease molecular pathogenesis could provide useful tools for COVID-19 patients in surveillance, prognosis, treatment, vaccine development and therapeutic targeting. The present research aims to summarize the association in COVID-19 patients between molecular dimensions of comorbidities with clinical and preclinical information. Developing an ACE2 inhibitor could be a possible therapeutic target. Plasmin is another possible candidate both in diagnosis and treatment areas. All predicted biomarkers must be validated either through randomized clinical trials or experimental assays before clinical application in patients.

    Abstract The transforming growth factor-beta (TGF-β) signaling pathway has been reported to be dysregulated in the pathogenesis of several malignancies, including gynecologic cancers. This provides proof of concept of its potential value as a therapeutic target and prognostic biomarker in cervical cancer. Here we provide an overview of the biological role and clinical impact of TGF-β inhibitors either as a single agent or as a combinatorial therapy in gynecological cancers, concentrating on phase I to phase II/III clinical trials. Aberrant TGF-β signaling may lead to carcinogenesis. Inhibition of TGF-β represents an interesting area of focus for the treatment of gynecological cancer. Several TGF-β inhibitors are potential anticancer agents and are undergoing clinical trials in cancer, including galunisertib, dalantercept, and vigil. There is a growing body of data showing the potential therapeutic impact of targeting the TGF-β pathway in different cancer types, although further studies are still warranted to explore the value of this strategy and finding the most appropriate patients who could most benefit from therapy.

    Abstract Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continues to be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade that has given us a clearer picture of the pathogenesis of nontraumatic ANFH. Progression to the end stage of ANFH appears to be related to five main mechanisms: hypercoagulable conditions, angiogenesis suppressions, hyperadipogenesis, heritable states, and switching the bone remodelling into bone resorption. Researchers have been examining the pathogenic mechanisms of ANFH but none of these theories have been firmly confirmed although some appear more plausible than the others. All of these factors can switch bone remodelling into bone resorption, which can further lead to ANFH progression ending up to femoral head collapse.

    Abstract Background: Oxidized LDL receptor 1 (OLR1) encodes LOX-1, LOXIN, and OLR1D4 transcript variants. Up-regulation of LOX-1 and down-regulation of LOXIN have an essential role in causing coronary artery disease (CAD). Discovery of risk single nucleotide polymorphisms (SNPs) in OLR1 gene is clinically important as these polymorphisms could be candidate biomarkers of CAD.
    Objectives: The purpose of this study is quantitative evidence synthesis on how OLR1 polymorphisms in the haplotype block impact the risk of CAD.
    Methods: First, a systematic keyword-based search in PubMed, Web of Science, and Scopus was conducted. After data extraction, pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for OLR1 polymorphisms and CAD. Twelve case-control studies, including 6,238 cases and 15,773 controls, were concluded in the meta-analysis.
    Results: Our findings demonstrate significant association of OLR1 polymorphisms in the haplotype block with CAD risk in all genetic models (allelic model: OR = 1.19, 95%CI = 1.06-1.34; additive model: OR = 1.54, 95%CI = 1.16-2.05; recessive model: OR = 1.26, 95%CI = 1.04-1.53; dominant model: OR = 1.28, 95%CI = 1.09-1.51). Subgroup analysis based on the type of polymorphism revealed that rs1050283 (3'UTR*188 C > T) and rs3736235 (IVS4-14 A > G) are more significantly associated with the risk of CAD compared to other polymorphisms in the haplotype block.
    Conclusions: We found a significant association between OLR1 polymorphisms in the haplotype block, especially rs1050283 and rs3736235, with CAD. We also suggest that precise determination of disease association with polymorphisms in a haplotype requires investigation of all SNPs rather than a single SNP in that specific haplotype.

    Abstract Background: Anthropometry is a branch of anatomy. One of the important parts of anthropometry is cephalometry, which is characterized by anatomical dimensions of the head area. The aim of this study was to investigate the relationship between brain volume, weight, and IQ in children. Methods: This descriptive-analytical study was performed on 300 students. Conventional measuring instruments were used for anthropometric measurements. Body weight and skull dimensions were measured. Then, using the appropriate formulas, the volume and weight of the brain and the brain index were measured. Results: The Pearson correlation coefficient confirmed a weak correlation between the amounts of IQ and anthropometric dimension in female samples. The mean head circumference of males was 2 cm above the mean head circumference of females. Compared to the central index and the dispersion, anthropometric dimensions were significant between boys and girls. According to the analysis of neural network, the anthropometric dimensions of head height, brain weight, head width, and brain index in boys and anthropometric dimensions around the head volume of head width and head height in girls were the most important in relation to IQ. Conclusion: The results of this study showed that there was a significant statistical difference between the central index and the distribution of anthropometric dimensions in boys and girls. Moreover, there was not a significant relationship between IQ and anthropometric dimensions of the body. In girls, there was a weak correlation between IQ and head width, head height, brain volume, and brain weight.

    Abstract Abstract: Functional 1H magnetic resonance spectroscopy (fMRS) is a derivative of dynamic MRS imaging. This modality links physiologic metabolic responses with available activity and measures absolute or relative concentrations of various metabolites. According to clinical evidence, the mitochondrial glycolysis pathway is disrupted in many nervous system disorders, especially Alzheimer disease, resulting in the activation of anaerobic glycolysis and an increased rate of lactate production. Our study evaluates fMRS with J-editing as a cutting-edge technique to detect lactate in Alzheimer disease. In this modality, functional activation is highlighted by signal subtractions of lipids and macromolecules, which yields a much higher signal-to-noise ratio and enables better detection of trace levels of lactate compared with other modalities. However, until now, clinical evidence is not conclusive regarding the widespread use of this diagnostic method. The complex machinery of cellular and noncellular modulators in lactate metabolism has obscured the potential roles fMRS imaging can have in dementia diagnosis. Recent developments in MRI imaging such as the advent of 7 Tesla machines and new image reconstruction methods, coupled with a renewed interest in the molecular and cellular basis of Alzheimer disease, have reinvigorated the drive to establish new clinical options for the early detection of Alzheimer disease. Based on the latter, lactate has the potential to be investigated as a novel diagnostic and prognostic marker for Alzheimer disease.

    Abstract Background: Addiction leads to numerous physical and mental problems for the addicted person and consequently major problems for the relatives. Objectives: The current study aimed at investigating the psychodynamic characteristics of females with addicted husbands in Kerman, Iran. Methods: In the current cross sectional study, 60 volunteer females with addicted husbands were compared with 60 wives of non-addict males. The thematic apperception (TAT) projective test along with the Ruben scoring system was used to evaluate the sample units. Data were collected from September 2015 to February 2016 and analyzed using t test and the Pearson chi-square test with SPSS software version 20. Results: The mean age of the case group was 32.6 ± 2.4 years with more children, compared with the control group (P < 0.05). The current study results showed a significant relationship between the groups regarding main conflict (P < 0.001), defence mechanism (immature defence P < 0.003 and neurotic defence P < 0.001), adequacy of superego (P < 0.001), feelings such as anger (P < 0.001) and guilt-frustration (P < 0.048), and unfavorable outcomes (P < 0.001). Conclusions: Understanding and perception of the nature of addiction, how to deal with it, and cope with the addict bring a deep challenge to the personality characteristics of the addict’s spouse. In consequence, such scenarios lead to conflicting communications among them and they turn to the frequent use of immature and neurotic defence mechanisms such as identification and cope with the problem in the interpersonal relationships. Identification of the characteristics of such females helps to employ better strategies to improve their quality of life.
