Pesticin-Like Effector VgrG3 Targeting Peptidoglycan Delivered by the Type VI Secretion System Contributes to Vibrio cholerae Interbacterial Competition.

Vibrio cholerae can utilize a type VI secretion system (T6SS) to increase its intra- and interspecies competition. However, much still remains to be understood about the underlying mechanism of this intraspecies competition. In this study, we isolated an environmental V.

Interleukin-18 promotes the antitumor ability of natural killer cells in colorectal cancer via the miR-574-3p/TGF-β1 axis.

Interleukin (IL)-18 has a clear antitumor effect; however, its mechanisms of action are not understood in patients with colorectal cancer (CRC). Here, we investigated the potential mechanism of IL-18 in CRC. The results showed that IL-18 treatment alone had no effect on HCT116 cells apoptosis, whereas IL-18 in the presence of natural killer (NK) cells resulted in apoptosis and inhibition of cells proliferation in vitro.

The expressions and significance of B7-H3 and CTLA-4 in the clinical stages of non-small-cell lung cancer.

The aim of this study was to analyze the expressions and significance of B7-H3 and CTLA-4 in the clinical stages of non-small-cell lung cancer (NSCLC). Seventy patients with NSCLC who underwent surgical resection or biopsy between January 2016 and February 2018 were enrolled. Among them, 30 were cases of paracancerous tissues and were assigned to the control group (CON).

Clinical relevance of using autofluorescence bronchoscopy and white light bronchoscopy in different types of airway lesions.

Objectives: The aim of this study was to evaluate the sensitivity and specificity of autofluorescence bronchoscopy (AFB) according to the macroscopic appearance of airway lesions under white light bronchoscopy (WLB).

Materials And Methods: The bronchoscopic findings of 708 patients, who were pathologically and clinically diagnosed with airway lesions and underwent both WLB and AFB, were analyzed.

Results: We recruited 708 patients for this study, of which 336 (47.

[Value of peritoneoscopy via natural orifice transluminal endoscopic surgery in the diagnosis of peritoneal carcinomatosis].

Objective: To evaluate the value of peritoneoscopy via natural orifice transluminal endoscopic surgery (NOTES) in the diagnosis of patients with peritoneal carcinomatosis.

Methods: A total of 32 patients with peritoneal carcinomatosis were diagnosed by histological examination of biopsies at our hospital from April 2007 to October 2010. Their data of clinical manifestations, gastroscopy, colonoscopy, abdominal ultrasonography, abdominal computed tomography, magnetic resonance imaging, ascitic cytology and transgastric peritoneoscopy via NOTES were analyzed retrospectively.
