Background: Controlling healthcare-associated infections (HAIs) remains one of the major challenges faced by healthcare systems worldwide. Effective management of HAIs has become a critical indicator for evaluating the quality of services provided by medical institutions.
Aim: This study aims to compare the outcomes of environmental and instrument cleaning audits using an adenosine triphosphate (ATP) bioluminescence assay to prevent the spread of micro-organisms within medical environments.
Methods: The ATP monitoring system employs a cold light instrument integrated with bioluminescence enzyme detection technology. One hundred and ninety-one points were evaluated in 2020, 158 points in 2021, and 146 points in 2022.
Findings: From 2020 to 2022, the rate of environmental cleaning compliance (<200 relative light units (RLU)) in the radiology department increased from 82% to 92%, while the rate of excellent cleanliness (<100 RLU) improved significantly from 58% to 86% (<0.001). Our findings indicate that medical instruments and high-touch clinical instrument surfaces (HTCIS) in areas frequently contacted by patients are the primary contributors to the spread of pathogenic bacteria.
Conclusions: HTCIS should remain a focal point for improving environmental cleanliness and subsequent inspections in the radiology department. Enhancing the cleanliness of these surfaces is a vital strategy to prevent further nosocomial transmission.

The cytoskeleton is crucial for cell organization and movement. In Eukaryotes, it largely consists of the protein actin, that forms a double-stranded linear filamentous structure in the presence of ATP and disassemble upon ATP hydrolysis. Bacteria also possess actin homologs, that drive fundamental cellular processes, including cell division, shape maintenance, and DNA segregation.

Secretory phospholipase A2 group IB (sPLA2-IB) and M-type phospholipase A2 receptor (PLA2R) are closely related to proteinuria and idiopathic membranous nephropathy (IMN). Podocytes are important components of the glomerular filtration barrier and glucose metabolism, including glycolysis and tricarboxylic acid (TCA) cycle, is crucial for maintaining podocyte physiological function. Aberrant energy metabolism has been reported in proteinuria diseases, including diabetic nephropathy.

Unlabelled: Hypoxia is a part of many pathological and some physiological processes. It also occurs as a result of surgical techniques associated with limiting the blood supply to the operated organs and tissues. Hypoxia leads to a significant decrease in the ability of cells to implement energy-dependent processes due to a reduced contribution of mitochondria to the synthesis of adenosine triphosphate (ATP).

SNS-032 is a synthetic compound that specifically inhibits cyclin-dependent kinases 2, 7 and 9. Its primary anticancer activity involves cell cycle arrest, which prevents tumor cell growth. However, there are limited reports on whether SNS-032 induces pyroptosis, a novel inflammation-mediated programmed cell death pathway in breast cancer (BC).

Background: Microenvironmental alterations induce significant genetic and epigenetic changes in stem cells. Mitochondria, essential for regenerative capabilities, provide the necessary energy for stem cell function. However, the specific roles of histone modifications and mitochondrial dynamics in human adipose-derived stem cells (ASCs) during morphological transformations remain poorly understood.
