This study was designed to investigate the value of red blood cell distribution width (RDW), prealbumin (PA), platelet lymphocyte ratio (PLR), and carcinoembryonic antigen (CEA) in diagnosis colorectal cancer. There 500 cancer (CRC) patients, 250 polyps healthy volunteers performed complete counts with automated differential counts. The differences RDW, PA, PLR, CEA among three groups were statistically significant (P<0.05). CEA, RDW+PA+PLR+CEA all had a high accuracy rate for divided into...

Background: Klebsiella pneumoniae is a significant pathogen responsible for wide range of infections, particularly urinary tract infections (UTIs). We aimed to determine the prevalence extended-spectrum beta-lactamase (ESBL)-producing strains and analyze their antibiotic resistance patterns in isolates collected from patients three hospitals Isfahan, Iran. Methods: This study was conducted over 13-month period (2022–2023) educational Out 350 clinical specimens obtained with UTIs, wounds,...

The aim of this study was to investigate the prevalence Tropheryma whipplei, Chlamydia psittaci, pneumoniae, Legionella, Brucella, and Francisella tularensis in valve samples from endocarditis patients using real-time PCR method at a major referral heart hospital Iran. In study, 146 paraffin-embedded tissue valves with clinical pathological evidence infective (IE), who underwent replacement surgery between 2016 2020 Tehran Heart Center were collected. After DNA extraction samples, they...

Background: Yersinia enterocolitica is a gram-negative bacteria and one of the most important food-borne that causes yersiniosis. Several studies have investigated various species this gastrointestinal pathogen in food water sources. Although Olivier salad ready-to-eat easily available cold food, it highly susceptible to microbial contaminations. This study aims investigate presence spp., especially pathogenic salad. Methods: In cross-sectional descriptive study, 150 specimens (traditional...

Background: Food-borne diseases are one of the major problems in developing countries. This study aims to investigate prevalence, antibiotic resistance pattern, and serotyping Shigella isolates from Olivier salad. Methods: 150 samples salad, including 50 industrial 10 different available brands Tehran's shops 100 traditional southern regions, were randomly obtained between April October 2021. These examined for bacterial isolation identification, which was finally confirmed by API-20E kit....

Young (1 ml plasma, through tail vein, 3 days weekly for 4 weeks) E2 (30 mg/kg, SC, 5 administrated OVX The open field, elevated plus maze, Barne's maze used assess behaviors....

The resistance genes encoding aminoglycoside-modifying enzymes (AMEs) are now widely prevalent in different populations of Staphylococcus aureus. study aimed to determine the frequency AMEs-encoding clinical isolates S. A total 105 aureus were obtained from samples; and then identified by conventional biochemical tests. antibiotic patterns characterized agar disk diffusion method. distribution AMEs femA was determined multiplex PCR. aminoglycoside rates kanamycin, tobramycin, gentamicin,...

Background: Exotoxin A (ExoA) is one of the most known and important virulence factors Pseudomonas aeruginosa. This toxin cause ADP-ribosylation in eukaryutic Elongation Factor- 2 (EF-2), which results protein synthesis inhibition. Recent studies had shown immunostimulational characteristics detoxified ExoA. Our aim this study was to evaluate immunological properties ExoA by Serum Bactericidal assay, comparison with ELISA. Methods: The production done on ExoA-producing strain, aeruginosa...
