Article Synopsis
  • The RND superfamily of multidrug efflux systems is crucial for antibiotic resistance in gram-negative pathogens, specifically highlighting how the CmeABC system in a major enteric pathogen extrudes antibiotics.
  • A new variant, RE-CmeABC, has emerged in clinical isolates, showing enhanced resistance due to specific amino acid changes in RE-CmeB and a promoter mutation, though the exact molecular mechanisms for its improvements are still unclear.
  • RE-CmeABC is spreading globally among diverse strains, particularly associated with human infections, suggesting the variant's clinical significance, while evolutionary evidence hints at its origin and expansion driven by antibiotic selection pressure.

Following pancreatic resection, there may be a variety of complications, including wound infection, haemorrhage, and abdominal infection. The placement of drainage channels during operation may decrease the chances of postoperative complications. However, what kind of drainage can decrease the rate of postoperative complications is still a matter of debate.

ACSMs play critical roles in lipid metabolism; however, their immunological function within the tumor microenvironment (TME) remains unclear, especially that of ACSM6. In this study, we investigate the latent effect of ACSM6 on bladder cancer (BLCA). Several real-world cohorts, including the Xiangya (in-house), The Cancer Genome Atlas (TCGA-BLCA), and IMvigor210 cohorts, with TCGA-BLCA cohort serving as the discovery cohort were compared.

Article Synopsis
  • Prophages significantly influence the transfer of traits like virulence and antimicrobial resistance genes, although their role in the latter is still debated.
  • SMphages, a common type of prophage in Streptococcus, carry 25 antimicrobial resistance genes, making them resistant to ten drug classes, including critical vancomycin and oxazolidinone antibiotics.
  • These prophages integrate into bacterial chromosomes, can be excised when induced, and transfer rapidly via high-frequency conjugation, contributing to the spread of antimicrobial resistance within Streptococcus species.

Aberrant changes in site-specific core fucosylation (CF) of serum proteins contribute to cancer development and progression, which enables them as potential diagnostic markers of tumors. An optimized data-dependent acquisition (DDA) workflow involving isobaric tags for relative and absolute quantitation-labeling and enrichment of CF peptides by lens culinaris lectin was applied to identify CF of serum proteins in a test set of patients with nonalcoholic steatohepatitis (NASH)-related cirrhosis ( = 16) and hepatocellular carcinoma (HCC, = 17), respectively. A total of 624 CF peptides from 343 proteins, with 683 CF sites, were identified in our DDA-mass spectrometry (MS) analysis.

The banning of colistin as a feed additive for food-producing animals in mainland China in 2017 caused the decline in the prevalence of Escherichia coli-mobilized colistin resistance () in China. Salmonella Typhimurium and its monophasic 1,4,[5],12:i:- variants are also the main species associated with the spread of ; however, the evidence of the prevalence and transmission of among Salmonella is lacking. Herein, the 5,354 Salmonella isolates recovered from fecal samples of diarrheal patients in Guangdong, Southern China, from 2009 to 2019 were screened for colistin resistance and , and -positive isolates were characterized based on whole-genome sequencing (WGS) data.

Single-minded homolog 2 (SIM2) has been identified as a potential contributor to the development of solid tumors. Despite this, there is a lack of comprehensive research regarding its biological role and underlying mechanism within pancreatic cancer (PC), as well as its prognostic impact. This study systematically evaluated the expression level and clinical significance of SIM2 in patients with PC using various databases, including The Cancer Genome Atlas, KM Plotter, and gene expression profiling interactive analysis.

Aims: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus belonging to the Coronaviridae family that causes coronavirus disease (COVID-19). This disease rapidly reached pandemic status, presenting a serious threat to global health. However, the detailed molecular mechanism contributing to COVID-19 has not yet been elucidated.

Fluoroquinolone (FQ) resistance in a major foodborne bacterial pathogen, , derived from cattle has recently become prevalent and poses a significant public health concern. However, the underlying factors for this increase are not entirely clear. To evaluate the effect of enrofloxacin treatment on FQ-resistance development in , 35 commercial calves were equally divided into five groups (Groups 1-5) and were orally inoculated with FQ-susceptible (FQ-S) .

Background: The prognostic nutrition index (PNI), which has been evaluated in various kinds of cancers, offered a simple yet effective approach to predict the prognosis. The aim of this meta-analysis is to reveal the correlation between preoperative PNI and the prognosis of patients with pancreatic ductal adenocarcinoma (PDAC) who underwent curative resection.

Methods: We searched the PubMed, Embase, Web of Science and Cochrane Library databases, and extracted the hazard ratio (HR) with 95% confidential interval (CI) from eligible studies.

Background: Bladder carcinoma (BLCA) is a heterogeneous disease that makes it difficult to achieve proper individual treatment and predict prognosis. This study aimed to develop a risk score from a new perspective of pyroptosis and guide accurate treatment and prognosis prediction for BLCA.

Methods: The TCGA-BLCA cohort data were downloaded from The Cancer Genome Atlas database.

Background: Pancreatic cancer mortality is growing every year, and radical resection is the most essential therapy strategy. It is critical to evaluate the long-term prognosis of individuals receiving radical surgery. CA19-9 is a biomarker for patient recurrence and survival, however obstructive jaundice has a significant impact on this index.

is a leading cause of foodborne gastroenteritis. Recent studies have indicated a rise in fluoroquinolone-resistant (FQ-R) in cattle, where FQ is used to control bovine respiratory disease (BRD). To assess the effect of danofloxacin treatment on the development of FQ-resistance in , 30 commercial calves were divided into Group 1, Group 2, and Group 3 ( = 10), and were all inoculated orally with FQ-susceptible (FQ-S) ; seven days later, Group 3 was challenged with transtracheal , and one week later, Group 2 and Group 3 were injected subcutaneously with danofloxacin.

Background: Comparison between endosonographic ultrasonography (EUS)-guided celiac ganglia neurolysis (CGN) and EUS-guided celiac plexus neurolysis (CPN) in pain management for pancreatic cancer has engendered controversy. To analyze the effectiveness and safety of EUS-CGN and figure out whether EUS-CGN is better than EUS-CPN, a qualitative systematic review was conducted.

Methods: Studies were searched from Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE up to April 2020.

Article Synopsis
  • Campylobacter enterocolitis has been linked to the development of post-infection irritable bowel syndrome (PI-IBS), but the specific strain characteristics responsible for this risk remain unclear.
  • Researchers conducted pangenome-wide association studies and phenotypic tests on C. jejuni isolates from patients with and without PI-IBS and identified key genetic differences associated with the condition.
  • A risk-score model was developed using 22 genomic markers, highlighting the potential of specific C. jejuni genotypes to enhance virulence and increase PI-IBS risk, which could improve our understanding of host-pathogen interactions.

Accumulating studies have revealed that up- or downregulated miRNA-196 expression correlates with the prognostic value in various malignancies; however, existing single studies lack robust evidence to elucidate the role of miRNA-196 in malignancy. The pooled results showed that the upregulation of miRNA-196 expression was significantly correlated with unfavorable OS [HR 2.14; 95% confidence interval (CI), 1.

We describe here the gross and microscopic lesions in 18 experimentally induced and 120 natural abortions. In natural abortions, gross lesions were reported infrequently; placentitis was recorded in 6% and hepatic lesions in 4% of our field cases. Placentitis was the microscopic lesion identified most consistently in natural abortions (93%) and was often observed in association with abundant bacterial colonies in chorionic villi (54%) and less often with placental vasculitis (13%).
