Antibiotic resistance genes in plague ecosystems: Threatening the emergence of resistant plague.

The study aimed to investigate the prevalence of antibiotic resistance genes (ARGs) within the ecosystem of natural plague foci, assessing their potential impact on the efficacy of plague treatments. Employing 16S rRNA gene sequencing and high-throughput quantitative PCR, microbial communities and ARGs were detected, with subsequent analysis of interactions among ARGs, mobile genetic elements (MGEs), environmental factors, and microbial species. Tetracycline resistance genes were found to be dominant, with multidrug and tetracycline resistance ARGs primarily associated with marmots and ecological soil, while pikas predominantly harbored β-lactam resistance ARGs.

Metformin Attenuates Vocal Fold Fibrosis via AMPK Signaling.

Vocal fold fibrosis is a challenging condition with no clear consensus on effective treatment methods. Given the demonstrated efficacy of metformin in treating various fibrotic diseases, we hypothesized that metformin could reduce vocal fold fibrosis via the AMPK signaling pathway. In our study, we induced vocal fold injury in rabbits and administered metformin intraperitoneally at a dose of 250 mg/kg two weeks post-injury.

Implications of ITCH-mediated ubiquitination of SIX1 on CDC27-cyclinB1 signaling in nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) presents a significant medical challenge due to its high incidence rate and poor prognosis, which are attributed primarily to tumor metastasis and drug resistance. Sine oculis homeobox homolog 1 (SIX1) has been identified as a crucial target for cancer treatment. However, its role in NPC remains incompletely understood.

The association between albumin-corrected calcium and prognosis in patients with cardiac arrest: a retrospective study based on the MIMIC-IV database.

Background: Cardiac arrest (CA) is one of the leading causes of death globally, characterized by high incidence and mortality. It is of particular significance to determine the prognosis of patients with CA early and accurately. Therefore, we aim to investigate the correlation between albumin-corrected calcium (ACC) and the prognosis in patients diagnosed with CA.

Construction of the flagellin F mutant of Vibrio parahaemolyticus and its toxic effects on silver pomfret (Pampus argenteus) cells.

Vibrio parahaemolyticus causes diseases in aquatic organisms, leading to substantial financial losses to the aquaculture industry; its flagellin F (flaF) protein triggers severe inflammation in host cells. To enhance the understanding of the function of flaF in V. parahaemolyticus infection, in this study, a flaF-deficient mutant was constructed by employing two-step homologous recombination.

CRP and ALT Levels in Individuals with Acute Biliary Pancreatitis after Endoscopic Retrograde Cholangiopancreatography and Endoscopic Sphincterotomy.

Objective: The goal of this study was to see how effective endoscopic retrograde cholangiopancreatography combined with endoscopic sphincterotomy was in treating acute biliary pancreatitis and how it affected CRP and ALT levels.

Methods: This analysis is based on a 100-patient acute pancreatitis (ABP) study conducted at our institution from June 2019 to June 2020. They were divided into two groups of 50 cases each, the control group and the observational group, according to the random number table.

Probiotic in the prevention of ventilator-associated pneumonia in critically ill patients: evidence from meta-analysis and trial sequential analysis of randomized clinical trials.

Background: Probiotic might have a role in the prevention of ventilator-associated pneumonia (VAP) among mechanically ventilated patients, but the efficacy and safety remained inconsistent. The aim of this systematic review and meta-analysis was to evaluate the efficacy and safety of probiotic (prebiotic, synbiotic) versus placebo in preventing VAP in critically ill patients undergoing mechanical ventilation.

Methods: PubMed, Embase and the Cochrane library databases were searched to 10 October 2021 without language restriction for randomized or semi-randomized controlled trials evaluating probiotic (prebiotic, synbiotic) vs.
