From kamishibai card to key card: a family-targeted quality improvement initiative to reduce paediatric central line-associated bloodstream infections.

Background: Central line-associated bloodstream infections (CLABSIs) are major contributors to preventable harm in the inpatient paediatric setting. Despite multiple guidelines to reduce CLABSI, sustaining reliable central line maintenance bundle compliance remains elusive. We identified frontline and family engagement as key drivers for this initiative.

Insights into pathogenesis of fatal COVID-19 pneumonia from histopathology with immunohistochemical and viral RNA studies.

Introduction: We describe post-mortem pulmonary histopathologic findings of COVID-19 pneumonia in patients with a spectrum of disease course, from rapid demise to prolonged hospitalisation.

Methods And Results: Histopathologic findings in post-mortem lung tissue from eight patients who died from COVID-19 pneumonia were reviewed. Immunohistochemistry (IHC) and next-generation sequencing (NGS) were performed to detect virus.

Comparative proteomic analysis of protein methylation provides insight into the resistance of hepatocellular carcinoma to 5-fluorouracil.

Protein methylation is one of the common post-translational modifications involved in diverse biological processes including signal transduction, transcriptional regulation, DNA repairing, gene activation, gene repression, and RNA processing. Due to technique limitation, the investigation of protein methylation in cancer cells is not well achieved, which hinders our understanding of the contribution of protein methylation to drug resistance. In this study, we analyzed the methylproteomes of both 5-fluorouracil (5-Fu) resistant Bel/5-Fu cell line and its parental Bel cell line by employing SPE-SCX based label-free quantitative proteomics.

Circadian Clock, Time-Restricted Feeding and Reproduction.

The goal of this review was to seek a better understanding of the function and differential expression of circadian clock genes during the reproductive process. Through a discussion of how the circadian clock is involved in these steps, the identification of new clinical targets for sleep disorder-related diseases, such as reproductive failure, will be elucidated. Here, we focus on recent research findings regarding circadian clock regulation within the reproductive system, shedding new light on circadian rhythm-related problems in women.

Model systems for studying the assembly, trafficking, and secretion of apoB lipoproteins using fluorescent fusion proteins.

apoB exists as apoB100 and apoB48, which are mainly found in hepatic VLDLs and intestinal chylomicrons, respectively. Elevated plasma levels of apoB-containing lipoproteins (Blps) contribute to coronary artery disease, diabetes, and other cardiometabolic conditions. Studying the mechanisms that drive the assembly, intracellular trafficking, secretion, and function of Blps remains challenging.

First-trimester maternal serum alpha fetoprotein is associated with ischemic placental disease.

Background: While elevated second-trimester maternal serum alpha fetoprotein has been associated with adverse pregnancy outcomes, the utility of first-trimester maternal serum alpha fetoprotein in predicting these outcomes is limited. Some laboratories have been including maternal serum alpha fetoprotein as part of the first-trimester analyte screening for aneuploidy and preeclampsia, offering its potential utility in predicting pregnancy outcomes.

Objective: Our primary objective was to determine the association between elevated first-trimester maternal serum alpha fetoprotein and preeclampsia as well as ischemic placental disease (a composite of preeclampsia, fetal growth restriction, and/or placental abruption).

BMAL1 controls glucose uptake through paired-homeodomain transcription factor 4 in differentiated Caco-2 cells.

The transcription factor aryl hydrocarbon receptor nuclear translocator-like protein-1 (BMAL1) is an essential regulator of the circadian clock, which controls the 24-h cycle of physiological processes such as nutrient absorption. To examine the role of BMAL1 in small intestinal glucose absorption, we used differentiated human colon adenocarcinoma cells (Caco-2 cells). Here, we show that BMAL1 regulates glucose uptake in differentiated Caco-2 cells and that this process is dependent on the glucose transporter sodium-glucose cotransporter 1 (SGLT1).
