Urinary bio-monitoring of aromatic amine derivatives by new needle trap device packed with the multi-component adsorbent.

Aromatic amines are a large group of chemical compounds that have attracted the attention of researchers due to their toxicity and carcinogenicity. This study aimed to develop an efficient method for sampling and analysis of aromatic amines (Aniline, N, N-dimethylaniline, 2-chloroaniline, and 3-chloroaniline) from the vapour phase (headspace) of urine samples. For the implementation of this plan, a needle trap device packed with the three-component adsorbent consisting of nano-Hydroxy Apatite (nHA), Zeolite (Ze), and Metal-Organic Framework (MOF) equipped with GC-FID was employed for the first phase.

Novel Mutation Associated with Vici Syndrome Gene.

Introduction: Vici syndrome (also known as immunodeficiency with cleft lip/palate, cataract, and hypopigmentation and absent corpus callosum) is considered as a progressive neurodevelopmental multisystem disorder. Till date, only 80 cases, including our patient, with this syndrome have been reported .This syndrome is characterized by agenesis of the corpus callosum, hypopigmentation of the eyes and hair, cataract, cardiomyopathy, combined immunodeficiency, hearing loss, seizures, and additional multisystem involvements which have been reported as case reports in the past.

An Overview of Antibiotic Resistance and Abiotic Stresses Affecting Antimicrobial Resistance in Agricultural Soils.

Excessive use of antibiotics in the healthcare sector and livestock farming has amplified antimicrobial resistance (AMR) as a major environmental threat in recent years. Abiotic stresses, including soil salinity and water pollutants, can affect AMR in soils, which in turn reduces the yield and quality of agricultural products. The objective of this study was to investigate the effects of antibiotic resistance and abiotic stresses on antimicrobial resistance in agricultural soils.

Atherosclerosis and multiple sclerosis: An overview on the prevalence of risk factors.

Background: Atherosclerosis is the leading cause of ischemic heart disease and coronary artery disease. The process of atherosclerosis develops over a period of years and is mainly immune-mediated. Data regarding the prevalence of vascular disease and atherosclerosis among people with multiple sclerosis (pwMS) is inconsistent, therefore, we aimed to provide an overview of the prevalence of atherosclerotic risk factors in pwMS.

Information Needs of Pregnant Women in the COVID-19 Pandemic from Experts' Point of View: A Qualitative Study.

Background: As pregnant women are among vulnerable groups susceptible to respiratory infections, healthcare systems in most countries would pay more attention to providing the services required in the COVID-19 pandemic. The present study aims to identify the information needs of pregnant women during the COVID-19 pandemic.

Methods: The research team conducted a qualitative conventional content analysis with an inductive approach to identify the views of 19 experts when working in the field of providing obstetric and midwifery services in Isfahan from April to June 2020.

Enhancing academic engagement of underachieving gifted students: The effects of Martin's educational program.

Introduction: Gifted students are superior to their peers in terms of cognitive, educational, scientific, creativity, and artistic abilities. There are also gifted students who struggle with cognitive, educational, social, emotional, and behavioral development, especially academic performance. They are called underachieving students.

Protective Effect of HLA-E∗0101∕∗0103 Genotype in Survival of Patients After Allogeneic Hematopoietic Stem Cell Transplant.

Objectives: HLA-E is located on the nonclassical major histocompatibility complex class I and acts as the ligand for natural killer cells. Consequently, it has a main role in the regulation of innate immune responses by involving cell identification by natural killer cells. Differences in expression levels among HLA-E alleles have been suggested to affect transplant outcomes.

The First Report of Differences in Gut Microbiota Composition between Obese and Normal Weight Iranian Subjects.

Background: OObesity is a complex disorder influenced by various genetic and environmental factors. It has been shown that gut microbiota, which colonizes gastrointestinal tract, has a substantial role as an environmental factor in the pathophysiology of obesity. Since the composition of gut microbiota alters with regard to different criteria, such as ethnicity, geographical location, diet, lifestyle, age, and gender, we aimed to determine firmicutes/bacteroidetes (F/B) ratio and the abundance of important gut microbiota members, Akkermansia muciniphila, Faecalibacterium prausnitzii, Roseburia, Bifidobacterium, and Prevotella in Iranian obese and normal weight individuals, for the first time.

ROCK Y-27632 Inhibitor, Ascorbic Acid, and Trehalose Increase Survival of Human Wharton Jelly Mesenchymal Stem Cells After Cryopreservation.

Objectives: Wharton jelly mesenchymal stem cells are good candidates for application in different aspects of regenerative medicine, and their long-time banking is important. In this study, the effects of trehalose, ascorbic acid, and Y-27632 on proliferation and survival rate of these cells after cryopreservation were investigated.

Materials And Methods: Mesenchymal stem cells were isolated from human umbilical cord Wharton jelly and frozen using a slow-rate cooling process.

Chemometric assisted ultrasound leaching-solid phase extraction followed by dispersive-solidification liquid-liquid microextraction for determination of organophosphorus pesticides in soil samples.

Ultrasound leaching-solid phase extraction (USL-SPE) followed by dispersive-solidification liquid-liquid microextraction (DSLLME) was developed for preconcentration and determination of organophosphorus pesticides (OPPs) in soil samples prior gas chromatography-mass spectrometry analysis. At first, OPPs were ultrasonically leached from soil samples by using methanol. After centrifugation, the separated methanol was diluted to 50 mL with double-distillated water and passed through the C18 SPE cartridge.

Novel Point Mutations in Frataxin Gene in Iranian Patients with Friedreich's Ataxia.

Objective: Friedreich's ataxia is the most common form of hereditary ataxia with autosomal recessive pattern. More than 96% of patients are homozygous for GAA repeat extension on both alleles in the first intron of FXN gene and the remaining patients have been shown to be heterozygous for a GAA extension in one allele and point mutation in other allele.

Materials & Methods: In this study, exons of 1, 2, 3, and 5 of frataxin gene were searched by single strand conformation polymorphism polymerase chain reaction (PCR-SSCP) in 5 patients with GAA extension in one allele.
