Investigation of the biofilm formation in extra-intestinal pathogenic Escherichia coli ST131 strains and its correlation with the presence of fimH, afa, and kpsMSTII genes.

Escherichia coli sequence type 131 (ST131) is a multidrug-resistant strain with the global dissemination. Biofilm formation-related factors include the most important virulence factors in extra-intestinal pathogenic E. coli (ExPEC) ST131 strains causing infections with treatment-limited subjects.

Prevalence of Listeria monocytogenes infection in women with spontaneous abortion, normal delivery, fertile and infertile.

Background: Listeria monocytogenes with a vast range of natural reservoirs is more known for being a food-borne pathogen. Human infections have shown an impact on pregnancy outcomes, so, this study surveyed the frequency of L. monocytogenes infection involving different groups of women.

DNMT1 Gene Expression in Patients with Infection.

DNMT1, as a critical enzyme affecting epigenetics through methylation of DNA cytosine-rich sequences, regulates gene expression. Exterior factors including long-term infections, in this study infection, could change host cells' epigenetics by affecting gene expression. This study investigated the statistical correlation between virulence genes and gene expression in gastric antral epithelial cells of gastric adenocarcinoma and gastritis patients.

and Genes Expression in Gastritis and Gastric Cancer Patients with Infection.

Background: and genes contribute to the cell cycle during proliferation and apoptosis, respectively. Designing a case-control study including gastric adenocarcinoma and gastritis patients with and without infection would lead to determinate of the correlations between and genes expression with infection in gastric antral epithelial cells.

Methods: Overall, 50 and 30 gastric antral biopsy samples of gastric cancer (case group) and gastritis (control group) patients were included into study, respectively.

Virulence genes, phylogenetic analysis, and antimicrobial resistance of Escherichia coli isolated from urinary tract infection in hospitalized patients and outpatients.

Uropathogenic Escherichia coli (UPEC) strains are the most common cause of urinary tract infection (UTI) in hospitalized and community patients. The aim was to compare the genetic characteristics of E. coli isolated from inpatients (IPs) and outpatients (OPs) with UTI regarding their phylogenies, virulence traits, and resistance trends.

Genotyping Helicobacter pylori and fgf7 gene expression in gastric cancer.

Background: Helicobacter pylori as the causative agent of the most common chronic bacterial infectious disease in human still involves a range of clinical challenging complications. In this meantime, the survey of the interaction between H. pylori virulence genes expression and its consequences on gastric antral epithelial cells is Controversial.

Sirt3, 6, and 7 Genes Expression in Gastric Antral Epithelial Cells of Patients with Helicobacter pylori Infection.

Sirtuins, known as the intracellular acylation enzymes, play a major role in regulating the cell's physiological activities. The relevant studies have shown diversely sirtuin genes expression in various cancers in humans. This study has surveyed the transcription of sirt3, 6, and 7 genes in gastric antral epithelial cells (GAECs) of gastritis and gastric adenocarcinoma patients with and without Helicobacter pylori infection.

PREX2 gene's expression in gastric antral epithelial cells of patients with H. pylori infection.

Background: The Prex2 protein is a member of the Rac family proteins that belongs to small G proteins with a critical role in cell migration, cell proliferation, and apoptosis through its effects on PI3K cell signaling pathway and phosphatase activity of PTEN protein. The effect of PREX2 gene expression has been shown in some cancer cells. A survey of PREX2 gene expression in gastric antral epithelial cells of gastric cancer patients with Helicobacter pylori various genotypes infection can conduct to better understanding H.

Prevalence of Neisseria gonorrhoeae in Western Iran.

Neisseria gonorrhoeae is the causative agent of the sexually transmitted disease gonorrhoea. This bacterium infects the epithelial cells of the cervix of women and the urethra of men. However, its disease symptoms in the lower genitalia are found only in a small percentage of people.

Transcriptional Profile of Virulence Genes in Patients with Gastritis and Gastric Cancer.

Introduction: Numerous molecular epidemiology studies have been performed about the frequency of virulence genes in patients with infection so far. This study was conducted to detect transcriptional profile by cDNA of virulence genes in gastric biopsy samples of gastritis and gastric carcinoma patients.

Materials And Methods: In a case-control study, based on the prevalence of gastritis and gastric cancer in Sanandaj city during 2018 and 2019, 23 and 11 gastric antral biopsy samples with infection were collected from gastritis and gastric carcinoma patients by the consecutive and available sampling method.

ZAK Gene Expression in Patients with Helicobacter pylori Infection.

Background: ZAK protein is a member of the MLK family proteins defined as mediators in the cell cycle. A survey of ZAK gene expression in gastric antral epithelial cells (GAECs) of gastritis and gastric adenocarcinoma patients with Helicobacter pylori genotypes infection can elucidate carcinogenesis of H. pylori genotypes.

Relationship between Genotypes Infection and IL-10 and TGFβ1 Genes' Expression in Gastric Epithelial Cells.

Background: The correlation of infection with gastritis, peptic ulcer, and gastric cancer has been proven. The aim of this study was to determine the effects of and genotypes of on genes expression of interleukin (IL) -10 and tumor growth factor (TGF) β1 in gastric epithelial cells of patients with gastritis and infection.

Methods: In all, 45 gastric biopsy samples were collected from patients with gastritis and infection admitted to Tohid Hospital in Sanandaj city.

Sirt1 Gene Expression and Gastric Epithelial Cells Tumor Stage in Patients with Helicobacter pylori Infection.

Introduction: The World Health Organization has categorized Helicobacter pylori as a carcinogen for gastric cancer, which causes human mortality worldwide. A number of studies have shown that H. pylori affects cell signaling in gastric epithelial cells and changes the expression of some proteins such as proinflammatory cytokines.
