Identification of in pulmonary and extrapulmonary specimens of Iranian hospitalized patients during 2017-2021.

Background: Tuberculosis (TB) is one of the most serious public health problems worldwide which is a chronic infectious disease and is still one of the major challenges for developing countries. This study was undertaken to identify Mycobacterium TB (MTB) in clinical specimens in hospitalized patients.

Methods: The study was carried out on specimens from pulmonary and extrapulmonary suspected TB patients that were admitted to one of the largest tertiary hospitals located in Tehran, Iran from 2017 to 2021.

The SARS-Cov-2 Proliferation Blocked by a Novel and Potent Main Protease Inhibitor via Computer-aided Drug Design.

The recent prevalence of novel " disease 2019" has expanded quickly globally, causing a universal pandemic. Herein, an effort was constructed to design a potent drug to inhibit the main protease of SARS-Cov-2 (3CLp) by means of structure-based drug design. A large library of the compounds was used for virtual screening.

Biogenic synthesis of AgNPs using Artemisia oliveriana extract and their biological activities for an effective treatment of lung cancer.

Silver nanoparticles (AgNPs) were synthesized using Artemisia oliveriana extract, and their physicochemical characteristics were studied. The antioxidant and antimicrobial activities of the AgNPs, as well as their anticancer effects on the lung cancer cell line (A549), using 1,1-diphenyl-2-picrylhydrazyl (DPPH), MIC and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) techniques respectively demonstrated that the synthesized AgNPs mainly affected the gram-positive bacteria rather than the gram-negative bacteria, and exhibited significant cellular toxicity on the A549 cell line. Further, the cellular uptake of the AgNPs results indicated that the AgNPs accumulated within the cell.

Apoptotic Effects of Linum album Extracts on AGS Human Gastric Adenocarcinoma Cells and ZNF703 Oncogene Expression.

Introduction: Linum album is a medicinal plant endemic in Iran that is very important pharmaceutically. The present study concerns the effect of different extracts of L. album on ZNF703 gene expression and apoptosis in human gastric carcinoma AGS cells.

Phytochemical composition and biological activities of Artemisia quettensis Podlech ethanolic extract.

The present study aim to investigate the phytochemical composition, antibacterial, antioxidant and anticancer activities of the ethanolic extract from aerial parts of Artemisia quettensis Podlech. The aerial part of A. quettensis Podlech extract was used for Gas chromatography-mass spectrometry (GC-MS) analysis, antioxidant, antibacterial and anticancer activities.

In Silico Analysis of L1/L2 Sequences of Human Papillomaviruses: Implication for Universal Vaccine Design.

The aim of this study was to design a multiepitope universal vaccine for major human papillomavirus (HPV) structural proteins, L1/L2, by bioinformatics models. For this purpose, we predicted the most probable immunogenic epitopes of L1 and L2 from common high-risk HPV 16, 18, 31, and 45 beside high prevalent type 6 and 11 based on BCPREDS defaulted model, while solvent accessibility of structure was extrapolated. The three-dimensional molecular model of L1 protein was constructed by Swiss Model server, whereas sequence alignment provided model for prediction of L2 protein epitopes.

Chemical composition, antioxidant, antibacterial and cytotoxic effects of Artemisia marschalliana Sprengel extract.

The present study was to investigate the gas chromatography/mass spectrometry (GC/MS), in vitro antioxidant, antibacterial and anticancer activity of the ethanolic extract from aerial parts of Artemisia marschalliana Sprengel against human gastric carcinoma (AGS) and L929 cell lines. Phytochemical analysis of A. marschalliana Sprengel extract showed 22 major components and the most dominant compounds were trans-phytol (29.

Draft Genome Sequence of Kocuria rhizophila RF, a Radiation-Resistant Soil Isolate.

Kocuria rhizophila RF, a soil isolate from Iran, is a radiation-resistant bacterium. Only a limited amount of genomic information for radiation-resistant bacteria is currently available. Here, we report the draft genome sequence of this bacterium, providing knowledge to aid in the discovery of the genomic basis of its resistance to radiation.

Genetic characterization of the wboA gene from the predominant biovars of Brucella isolates in Iran.

Introduction: Brucella spp. are gram-negative, facultative intracellular bacteria pathogens responsible for brucellosis, a zoonotic disease that can cause abortion, fetal death, and genital infections in animals and undulant fever in humans. Lipopolysaccharide (LPS) is known as a major virulence factor of Brucella spp.
