Several studies showed the efficacy of Lycium barbarum polysaccharide (LBP) in diabetic animals and patients with type 2 diabetes mellitus (T2DM). However, the mechanism of LBP in alleviating T2DM based on glucagon-like peptide 1 (GLP1) has not been suitably elucidated. GLP1 is an important peptide that plays a role in blood glucose homeostasis.

Parkinson's disease (PD) is a common neurodegenerative disease in the elderly with a pathogenesis that remains unclear. We aimed to explore its pathogenesis through plasma integrated metabolomics and proteomics analysis. The clinical data of consecutively recruited PD patients and healthy controls were assessed.

This study aims to assess the in vitro activity of different samples of cefoperazone/sulbactam (CFP/SUL) against multidrug-resistant organisms (MDROs). Clinical isolates of extended-spectrum β-lactamase (ESBL)-, ESBL-, carbapenem-resistant (CR-AB), and carbapenem-resistant (CR-PA) were collected. The minimum inhibitory concentration (MIC) and time-killing methods were used to assess and compare the in vitro activities of different samples of cefoperazone/sulbactam (CFP/SUL) against these MDROs.

New-Delhi metallo-β-lactamase1 (NDM-1) are increasing worldwide. Herein, we describe a single patient who carried three unusual NDM-1 carbapenem-resistant yielded from a urine specimen and and from stool specimens. For , its NDM-1-encoding plasmid was pKP04NDM with a size of ~54 kb replicons with an IncN backbone.

The empirical combination of both a beta-lactam and glycopeptide to counter potential staphylococcal pathogens may improve the clinical outcomes for cases of bacteremia. We reported comparative studies of combination effects of different cephalosporins (i.e.

Fenretinide is a novel anticancer agent reported to exhibit anti-invasive and antimetastatic activities. It has also been shown to improve obesity and diabetes, although the effects of fenretinide on hypertension are still unknown, and the detailed mechanisms remain unclear. In this study, we have shown that treatment with lipopolysaccharide (LPS) decreased the expression of peroxisome proliferator-activated receptor γ (PPARγ) in RAW264.

Background/purpose: The aim of this study is to investigate the role of tigecycline in Vibrio vulnificus infection.

Methods: Eight randomly selected clinical V. vulnificus isolates were studied to obtain the minimal inhibitory concentrations (MICs) of minocycline, cefotaxime, and tigecycline, and the time-kill curves of tigecycline alone or in combination with other drugs.

Background/purpose: In vitro studies of the combination of an aminoglycoside with tigecycline or doxycycline against Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae isolates are rarely published. The goal of this study was to evaluate the antibacterial activity of the combination regimens.

Background/purpose: This study was conducted to compare the mutation rates of different rpoB sites and rifampin minimum inhibitory concentration (MIC) changes prior to and after rifampin therapy for biofilm-embedded methicillin-resistant Staphylococcus aureus (MRSA) isolates.

Methods: The screening of rifampin-resistant MRSA isolates, from the biofilm at Day 5 with or without exposure to the susceptible breakpoint concentration of rifampin recommended by the Clinical and Laboratory Standards Institute (1 mg/L), was conducted using agar plates containing rifampin. A partial fragment of RNA polymerase B subunit gene (rpoB), including clusters I and II, was amplified and sequenced.

Vancomycin-resistant (VR) enterococci (VRE) are increasingly important nosocomial pathogens, commonly causing catheter-related urinary tract infections or vascular catheter-related bloodstream infections. In this study, 10 Enterococcus faecium and 9 Enterococcus faecalis different pulsed-field gel electrophoresis genome-type VR clinical isolates were detected. The potential role of fosfomycin-based combination regimens for biofilm-related VRE infection is in vitro evaluated.

To compare the in vitro antibacterial efficacies and resistance profiles of rifampin-based combinations against methicillin-resistant Staphylococcus aureus (MRSA) in a biofilm model, the antibacterial activities of vancomycin, teicoplanin, daptomycin, minocycline, linezolid, fusidic acid, fosfomycin, and tigecycline alone or in combination with rifampin against biofilm-embedded MRSA were measured. The rifampin-resistant mutation frequencies were evaluated. Of the rifampin-based combinations, rifampin enhances the antibacterial activities of and even synergizes with fusidic acid, tigecycline, and, to a lesser extent, linezolid, fosfomycin, and minocycline against biofilm-embedded MRSA.

The emergence of multidrug-resistant Salmonella isolates has created the need for new therapeutic agents. We evaluated the intracellular activity of four carbapenem compounds against clinical nontyphoid Salmonella (NTS) isolates in vitro and ex vivo. Subsequently, the efficacy of carbapenem treatment against selected Salmonella isolates in vivo was assessed using a murine peritonitis model.
