Background: Urinary Tract Infection (UTI) is one of the most common bacterial diseasesworldwidethat can be presented asymptomatic or symptomatic, characterized by a wide range symptoms from mild irritative voiding to bacteremia, sepsis, even death. In latter decades, widespread utilization antibiotics has resulted in increased incidence antibiotic resistance among urinary tract pathogens all over world. Objectives: The aim this study was determine patterns bacteria isolated infections city...

Hyperalgesia and hypersensitivity in patients with Inflammatory Bowel Disease (IBD) can be related to central nervous system (CNS) changes, particularly the pain pathways. The objective of this study was examine neuronal density cingulate cortex area (CC) amygdala an animal model colitis. In experiment, 13 male Wistar rats were subjected study. Colitis induced by transrectally administering 1 cc acetic acid 3% under sedation xylazine 10% (5 mg/kg). After 14 days colitis, euthanized high...

Staphylococcus saprophyticus (S. saprophyticus) is the second most prevalent etiological agent of urinary tract infections (UTIs) in young women. However, there a paucity data regarding its bacteriophage (phage). Therefore, this study was conducted to isolate and identify new lytic phages from municipal wastewater with objective increasing knowledge about their genomes. A total 11 clinical isolates S. 30 samples were used three (vB_SsapH-Golestan-100, vB_SsapH-Golestan101-M,...

This study was designed and conducted to evaluate the frequency, antimicrobial resistance, presence of six virulence-associated genes among thermophilic Campylobacters isolated from raw milk, poultry (chicken, turkey, duck), fish, cattle, sheep meat. Out 590 samples, which were recovered different origins, 141 (23.9%) samples positive for Campylobacters. Campylobacter spp. in 40.8% (106/260), 14% (28/200), 8.7% (7/80) meat, red milk respectively. Antimicrobial susceptibility test indicated a...

To investigate the prevalence of nine virulence and toxin genes Campylobacter, a total 90 Campylobacter strains including 48 C. jejuni 42 coli were recovered from chicken feces by cultivation methods. The isolates identified on basis polymerase chain reaction (PCR) detection 16SrRNA multiplex PCR for determining two species. For confirmed strains, was carried out presence using specific primers. Data analyzed SPSS software, version 12.0.1. cadF gene three associated with cytolethal...

Abstract Purpose To derive and validate an effective radiomics-based model for differentiation of COVID-19 pneumonia from other lung diseases using a very large cohort patients. Methods We collected 19 private 5 public datasets, accumulating to 26,307 individual patient images (15,148 COVID-19; 9,657 with e.g. non-COVID-19 pneumonia, cancer, pulmonary embolism; 1502 normal cases). Images were automatically segmented validated deep learning (DL) the results carefully reviewed. first cropped...

Probiotics are helpful bacteria that safeguard host animals from harmful pathogens. In fish farming, the primary aim of using probiotics is to preserve or reestablish a balance between pathogenic microorganisms and native constitute intestinal skin microbial communities fish. This study investigates effects host-associated probiotic (HAP) vs commercial (CP) on growth performance, antioxidant defense immunity Caspian whitefish fry. Three hundred fry (1.15 ± 0.03 g) were randomly divided into...

Abstract Background Notwithstanding the encouraging results of previous studies reporting on efficiency deep learning (DL) in COVID‐19 prognostication, clinical adoption developed methodology still needs to be improved. To overcome this limitation, we set out predict prognosis a large multi‐institutional cohort patients with using DL‐based model. Purpose This study aimed evaluate performance privacy‐preserving federated (DPFL) predicting outcomes chest CT images. Methods After applying...

Abstract Objective To determine the incidence of extra‐pulmonary tuberculosis (EPTB) and examine risk factors clinical features disease over a ten‐year period. Methods Retrospective study records patients who were followed registered in TB registry programme health district Gorgan, Iran from January 1, 2008, through December 31, 2017. Results Among 2280 records, 609 (26.71%) EPTB. They mostly female (53.7%) residents rural areas (56.5%) with mean age 40.55 years [±16]. The average (37.55...

Abstract To derive and validate an effective machine learning radiomics‐based model to differentiate COVID‐19 pneumonia from other lung diseases using a large multi‐centric dataset. In this retrospective study, we collected 19 private five public datasets of chest CT images, accumulating 26 307 images (15 148 COVID‐19; 9657 including non‐COVID‐19 pneumonia, cancer, pulmonary embolism; 1502 normal cases). We tested 96 learning‐based models by cross‐combining four feature selectors (FSs) eight...
