Effect of -induced gastric cancer on gastrointestinal microbiota: a narrative review.

() infection is a typical microbial agent that interferes with the complex mechanisms of gastric homeostasis by disrupting the balance between the host gastric microbiota and mucosa-related factors, ultimately leading to inflammatory changes, dysbiosis, and gastric cancer (GC). We searched this field on the basis of PubMed, Google Scholar, Web of Science, and Scopus databases. Most studies show that inhibits the colonization of other bacteria, resulting in a less variety of bacteria in the gastrointestinal (GI) tract.

Acceptance-Hesitancy of COVID-19 Vaccination and Factors Affecting It in Adults: Systematic Review Study.

Background: Despite the advent of vaccines against COVID-19, there is considerable variation in the acceptance and hesitancy towards the vaccination program across different countries. The objective of this study was to ascertain the prevalence of hesitancy and acceptance regarding the use of the vaccine against the novel coronavirus, also known as COVID-19, and to identify the factors that influence these attitudes.

Materials And Methods: All the cross-sectional studies were retrieved from the PubMed databases, the Web of Science ISI, Scopus, and the Cochrane Library.

Microbiome and bladder cancer: the role of probiotics in treatment.

Bladder cancer (BCa) remains a significant global health challenge, with increasing interest in the role of the bladder microbiome in its pathogenesis, progression and treatment outcomes. The complex relationship between bladder cancer and the microbiome, as well as the potential impact of probiotics on treatment effectiveness, is currently under investigation. Research suggests that the microbiota may influence BCa recurrence prevention and enhance the efficacy of the Bacillus Calmette-Guérin (BCG) vaccine.

The inhibitory effects of the novel cocktail on colorectal cancer development through modulating BMP signaling pathway: and in study.

This study investigates the impact of a five-strain cocktail (comprising two strains of , and one strain each of , , and ) on colorectal cancer (CRC) modulation by targeting the bone morphogenetic proteins (BMP) signaling pathway. Both and (models were employed. The antiproliferative effects of the cocktail on HT-29 cells were assessed via the MTT assay.

Role of Native Probiotic Lactobacillus Species via TGF-β Signaling Pathway Modulation in CRC.

Background: Colon microbiome composition in colorectal cancer (CRC) patients undergoes remarkable changes. The present study was designed to assess the impact of Lactobacillus mixture on the regulating the CRC by influencing the transforming growth factor beta (TGF-β) signaling pathway in both in vitro (HT-29 cancer cells) and in vivo (BALB/c mice) models.

Methods: In this study, the antiproliferative effect of a native potential probiotic Lactobacillus mixture on HT-29 cancer cells was evaluated using the MTT assay method.
