The role of exopolysaccharides Psl and Pel in resistance of to the oxidative stressors sodium hypochlorite and hydrogen peroxide.

Unlabelled: is well-known for its antimicrobial resistance and the ability to survive in harsh environmental conditions due to an abundance of resistance mechanisms, including the formation of biofilms and the production of exopolysaccharides. Exopolysaccharides are among the major components of the extracellular matrix in biofilms and aggregates of . Although their contribution to antibiotic resistance has been previously shown, their roles in resistance to oxidative stressors remain largely elusive.

Draft genome sequence of a methicillin-resistant strain isolated from a chronic wound.

We report the draft genome sequence and antimicrobial resistance gene profile of a methicillin-resistant (MRSA) clinical isolate recovered from a chronic pressure injury wound infection of an adult female patient. The draft genome sequence included a 2.86-Mb chromosome, which was accompanied by a 27-kb plasmid containing .

Impact of multicomponent intervention on hospitalized clinical patient outcomes: A pre-post study in a university hospital.

Background And Objective: Hospitalization significantly interferes with the individual's well-being and it occurs both during and after the hospitalization period. Different approaches to minimize morbidity related to hospitalization and the post-discharge period have been proposed, especially to those aimed at reducing readmission rates. The aim of this study is to evaluate the effect of multicomponent intervention (MI) on operational indicators and continuity of care outcomes.

Oxidative stress responses in biofilms.

Oxidizing agents are low-molecular-weight molecules that oxidize other substances by accepting electrons from them. They include reactive oxygen species (ROS), such as superoxide anions (O), hydrogen peroxide (HO), and hydroxyl radicals (HO), and reactive chlorine species (RCS) including sodium hypochlorite (NaOCl) and its active ingredient hypochlorous acid (HOCl), and chloramines. Bacteria encounter oxidizing agents in many different environments and from diverse sources.

Investigating ionizing radiation-induced changes in breast cancer cells using stimulated Raman scattering microscopy.

Significance: Altered lipid metabolism of cancer cells has been implicated in increased radiation resistance. A better understanding of this phenomenon may lead to improved radiation treatment planning. Stimulated Raman scattering (SRS) microscopy enables label-free and quantitative imaging of cellular lipids but has never been applied in this domain.
