KNOWLEDGE AND PREDICTORS OF IMPLEMENTATION OF STANDARD PRECAUTIONS FOR INFECTION PREVENTION AND CONTROL AMONG HEALTH CARE PRACTITIONERS.

Background: Infection prevention and control involve health care practitioners, who are saddled with the duty of ensuring implementation of standard preventive measures to prevent healthcare associated infections.

Objectives: To assess the knowledge and predictors of implementation of standard precautions for infection prevention and control among health care practitioners (HCPs).

Material And Method: A questionnaire-based cross-sectional design was employed in assessing HCPs in Uganda in from April - October 2023.

Investigating the nature of active forces in tissues reveals how contractile cells can form extensile monolayers.

Actomyosin machinery endows cells with contractility at a single-cell level. However, within a monolayer, cells can be contractile or extensile based on the direction of pushing or pulling forces exerted by their neighbours or on the substrate. It has been shown that a monolayer of fibroblasts behaves as a contractile system while epithelial or neural progentior monolayers behave as an extensile system.

The role of single cell mechanical behavior and polarity in driving collective cell migration.

The directed migration of cell collectives is essential in various physiological processes, such as epiboly, intestinal epithelial turnover, and convergent extension during morphogenesis as well as during pathological events like wound healing and cancer metastasis. Collective cell migration leads to the emergence of coordinated movements over multiple cells. Our current understanding emphasizes that these movements are mainly driven by large-scale transmission of signals through adherens junctions.
