Inhibition of biofilm formation and preformed biofilm in by resveratrol, chlorhexidine and benzalkonium: modulation of efflux pump activity.

Introduction: The persistence of in the contaminated environment is sustained by tolerance to biocides and ability to growth as biofilm. The aim of the study was to analyze the susceptibility of biofilms to chlorhexidine (CHX) and benzalkonium (BZK) biocides and the ability of natural monomeric stilbenoid resveratrol (RV) to modulate the phenomenon.

Methods: Biofilm formation and preformed biofilm were tested by Crystal violet and tetrazolium salt reduction assay, respectively.

In vivo assessment of the influence of general anaesthetics on transmembrane water cycling in the brain.

This study presents the first in vivo measurement of transcytolemmal water exchange in the brain using a novel Magnetic Resonance technique. We extend previous applications of Chemical Exchange Saturation Transfer (CEST) to examine water exchange across cellular membranes in late-stage chicken embryo brains. The immature blood-brain barrier at this stage allows Gadolinium-Based Contrast Agents (GBCAs) to penetrate the brain's interstitial space, sensitizing the CEST effect to water exchange between intra- and extracellular environments.

School health policies and their implementation during the COVID-19 pandemic in the Philippines.

Introduction: The COVID-19 pandemic has severely impacted the health and education of learners globally. However, there is a lack of information on enablers and barriers to the implementation of comprehensive school health policies during the pandemic.

Methods: This study utilized a case study design, and was conducted in the Division of City Schools of Navotas.

Structure-based targeting of the lipid A-modifying enzyme PmrC to contrast colistin resistance in .

Introduction: Antimicrobial-resistant pathogens are an ongoing threat to human and animal health. According to the World Health Organization (WHO), colistin is considered the last resort antibiotic against human infections due to multidrug-resistant Gram-negative organisms-including , a priority-1 pathogen. Despite colistin being considered a last resort antibiotic, transferable bacterial resistance to this drug has been reported in humans and animals.

Photobiomodulation and Physical Exercise Modulate of Cell Survival Proteins in the Skeletal Muscle of Rats with Heart Failure and Diabetes Mellitus.

Heart failure (HF) and type 2 diabetes mellitus (DM2) are global health problems that often lead to muscle atrophy. These conditions are associated with increased autophagy and apoptosis in the muscle cells, resulting in decreased muscle mass. Physical exercise associated with photobiomodulation (PBM) seems promising to attenuate the skeletal muscle changes caused by HF and DM2, due to its direct effects on mitochondria, which may result in an increase in antioxidant capacity.
