The influence of efflux pump, outer membrane permeability and β-lactamase production on the resistance profile of multi, extensively and pandrug resistant Klebsiella pneumoniae.

Background: An important chance of nosocomial acquired infections are caused by the opportunistic bacterium Klebsiella pneumoniae. Urine, wound, sputum, and blood samples were collected from all patients. This study aimed to detect the antibiotic resistance profile, the frequency of MDR, XDR, PDR, and detection of efflux pump and outer membrane permeability genes in K.

Evaluation of the effect of taurine on the matrix metalloproteinase-9 and the expression changes of miRNA-21 and miRNA-146a in SH-SY5Y cell line.

Objectives: Alzheimer's disease (AD), a brain disorder, is the leading cause of dementia among older adults. Taurine, an amino acid abundantly present in the brain, and shows potential neuroprotective properties. Therefore, we investigated the effects of taurine on Matrix Metalloproteinase-9 (MMP-9) levels and the expression changes of miRNA-21 and miRNA-146a in the SH-SY5Y cell line.

The role of endoplasmic reticulum stress in promoting aerobic glycolysis in cancer cells: An overview.

Aerobic glycolysis, also known as the Warburg effect, is a metabolic phenomenon frequently observed in cancer cells, characterized by the preferential utilization of glucose through glycolysis, even under normal oxygen conditions. This metabolic shift provides cancer cells with a proliferative advantage and supports their survival and growth. While the Warburg effect has been extensively studied, the underlying mechanisms driving this metabolic adaptation in cancer cells remain incompletely understood.

Effect of Cystamine on Sperm and Antioxidant Parameters of Ram Semen Stored at 4 °C for 50 Hours.

Physical and chemical changes caused by oxidative stress in the spermatozoa membrane can reduce spermatozoa function and even lead to death. Cystamine (NH2-CH2-CH2-SH, β-mercaptoethylamine) is a natural substance that modulates the endocrine and metabolic status of animals. This substance has antioxidant and anti-apoptotic effects by inducing intracellular cysteine accumulation.

Changes in medication use from age 26 to 32 in a representative birth cohort.

Background: To date, longitudinal studies of medications have been confined to older adults or clinical samples, with no data from prospective studies of younger adults. The aim of the study was to examine changes in medication usage between ages 26 and 32 in a prospective study of a representative birth cohort.

Methods: Medication use during the previous 2 weeks was investigated among 960 individuals at ages 26 and 32.

Xerostomia and medications among 32-year-olds.

Objective: To describe the prevalence and associations of xerostomia among adults in their early thirties, with particular attention to medication exposure as a putative risk factor.

Material And Methods: The prevalence and associations of xerostomia were investigated among 32-year-old participants in a long-standing prospective cohort study. Some 950 individuals were assessed at ages 26 and 32 years, with medications being recorded on both occasions.
