Statins, HMG-CoA reductase inhibitors could be associated with the risk reduction of colorectal cancer. We previously demonstrated that simvastatin inhibits NF-kappaB signaling in human intestinal epithelial cells and ameliorates acute murine colitis. The aim of our study was to evaluate the effects of simvastatin on the apoptotic pathways related to NF-kappaB signaling in colon cancer cells, and on anticancer effects in 2 different animal models. We treated cell lines (COLO 205 and HCT 116) wit

Continuous aspirin use increases the risk of bleeding after gastric ESD. Aspirin use should be stopped in patients with a low risk for thromboembolic disease to minimize bleeding complications.

<i>KMT2C</i> is frequently mutated in certain populations with DGA. KMT2C loss in DGA promotes EMT and is associated with worse overall survival.

The purpose of this cross-sectional study was to examine factors associated with nurses' resilience during the COVID-19 pandemic. Data were collected in the latter half of 2020 from 904 nurses across Japan, Republic of Korea, Republic of Turkey, and the United States. The questionnaire included the Connor-Davidson Resilience Scale 10, plus demographics and 20 questions about practice environment, workplace safety concerning infection control, COVID-related experience, and organizational support.

Endoscopic resection can be recommended if a low-grade dysplastic lesion has at least one of the following risk factors: depressed morphology, surface erythema, or a size of 1 cm or greater. For lesions that have none of the three risk factors, follow-up endoscopy is recommended.

As high OLGA and OLGIM stages are independent risk factors for gastric cancer, the staging systems may be useful for risk assessment in high-risk regions, especially for intestinal-type gastric cancer.

Young HCC patients showed a poorer prognosis than older HCC patients because they have a more advanced tumor stage at diagnosis. However, age was not an independent prognostic factor when stages were matched. Therefore, we suggest that periodic surveillance in young chronic hepatitis B virus carriers would improve outcomes.

MicroRNAs (miRNAs) play a critical role in gastric cancer progression and metastasis. This study investigated the role of miRNA-135a in early gastric cancer (EGC) including lymph node (LN) metastasis. We examined the correlation between miRNA-135a expression and clinical outcomes in 59 patients who underwent surgery for EGC. Using gastric cancer cell lines, we performed functional and target gene analyses. miRNA-135a expression was down-regulated in 33.9% of patients. These patients showed a sig

The bacterial diversity of the bovine rumen was examined using a PCR-based approach. 16S rDNA sequences were amplified and cloned from three fractions of rumen (solid, fluid, and epithelium) that are likely to represent different bacterial niches. A total of 113 clones were sequenced, and similarities to known l6S rDNA sequences were examined. About of the sequences had similarity to 16S rDNA database sequences. Furthermore, about of the sequences were similar to 16S rDNA database sequences. For

Helicobacter pylori eradication in GC patients is beneficial, as reflected by lower scores of atrophy and IM at 36 months after subtotal gastrectomy. (ClinicalTrials.gov number, NCT01002443).

The importance of PPARγ (peroxisome proliferator-activated receptor γ) in gastric cancer (GC) is unclear. We investigated the role of PPARγ in GC cell lines and an animal model, and its prognostic significance of PPARγ in GC patients. We controlled PPARγ and galectin-9 expression by using siRNAs and lentiviral constructs. Interaction between PPARγ and galectin-9 was evaluated using luciferase and chromatin immunoprecipitation assays. PPARγ expression in GCs was determined by immunohistochemical

The GDM management knowledge and tailored recommendations obtained in this study could be of help in managing GDM.

Intestinal-type gastric cancer often results from <i>Helicobacter pylori</i> infection through intestinal metaplasia, a transdifferentiated premalignant phenotype. Because <i>H. pylori</i> virulence factor CagA has been associated with aberrant expression of the transcription factor CDX1, which regulates intestinal differentiation, we explored its relationship with <i>H. pylori</i> infection and function during gastric carcinogenesis in normal gastric epithelial cells and gastric cancer cell lin

A bacterial strain, designated CY22, was isolated from the interior of balloon flower (Platycodon grandiflorum) root in the Republic of Korea. The isolate coproduced an iturin-like antifungal compound and a surfactin-like potent biosurfactant. Analysis of the 16S-rDNA of strain CY22 showed that the isolate was a member of Bacillus. High similarities were observed between strain CY22 and Bacillus sp. TKSP 24, and between strain CY22 and B. subtilis 168. Phylogenetic analysis based on 16S-rDNA seq
