Peracetic acid (PAA) is a strong oxidant/bactericide that has been applied in various industries (e.g., food processing, pharmaceuticals, medical device sterilization, etc.) as a disinfectant. There is increasing interest in using PAA for wastewater disinfection because it does not form halogenated byproducts, and no post-treatment quenching is required. Previous studies have demonstrated good efficiency in controlling bacteria in wastewater, but limited information is available for viruses, especially those hosted by mammals (e...

The heptapeptide angiotensin (Ang)-(1-7) is part of the beneficial arm of the renin-angiotensin system. Ang-(1-7) has cardiovascular protective effects, stimulates regeneration, and opposes the often detrimental effects of Ang II. We recently identified the G protein-coupled receptors Mas and MrgD as receptors for the heptapeptide. Ala1 -Ang-(1-7) (Alamandine), a decarboxylated form of Ang-(1-7), has similar vasorelaxant effects, but has been described to only stimulate MrgD. Therefore, this study aimed to characterise the consequences of the lack of the carboxyl group in amino acid 1 on intracellular signalling and to identify the receptor fingerprint for Ala1 -Ang-(1-7)...

Impairment of retinal pigment epithelial (RPE) cells is considered a key contributor to the development of age-related macular degeneration. Apoptosis-related protein 3 (APR3) was recently discovered after treatment with all- trans retinoic acid, a pivotal molecule in RPE cells. However, the function of APR3 remains poorly understood. In the present study, we found that APR3 could interact with nuclear factor (erythroid-derived 2)-like 2, which is a regulator of phase II enzymes, and that knockdown of APR3 promoted nuclear factor (erythroid-derived 2)-like 2 nuclear translocation and activated expression of phase II enzymes, which was accompanied by improved redox status and mitochondrial activity...

CONTEXT: The intravenous (IV) N-acetylcysteine (NAC) regimen used worldwide in paracetamol overdose is complex with three separate weight-based doses and is associated with a high incidence of adverse events including non-allergic anaphylactoid reactions (NAARs). In 2012, Denmark adopted the two-bag IV NAC regimen which combined the first two infusions of the three-bag regimen and kept the third infusion unchanged. We compared the safety and efficacy of the two-bag IV NAC regimen with the traditional Danish three-bag regimen...

Recent data shows that a neuromuscular block (NMB) induced by administration of high doses of rocuronium improves surgical conditions in certain procedures. However, there are limited data on the effect such practices on postoperative outcomes. We performed a retrospective analysis to compare unplanned 30-day readmissions in patients that received high-dose versus low-dose rocuronium administration during general anesthesia for laparoscopic retroperitoneal surgery. This retrospective cohort study was performed in the Netherlands in an academic hospital where routine high-dose rocuronium NMB has been practiced since July 2015...

In sub-Saharan Africa, invasive nontyphoidal Salmonella (iNTS) infections with serovars S. Enteritidis, S. Typhimurium and I 4,[5],12:i:- are widespread in children < 5 years old. Development of an efficacious vaccine would provide an important public health tool to prevent iNTS disease in this population. Glycoconjugates of S. Enteritidis core and O-polysaccharide (COPS) coupled to the homologous serovar phase 1 flagellin protein (FliC) were previously shown to be immunogenic and protected adult mice against death following challenge with a virulent Malian S...

BACKGROUND: Several studies have found that metabolic surgery can significantly improve glucose homeostasis; however, the intrinsic mechanisms remain unclear. Accumulating evidence suggests that duodenal bypass plays a crucial role in the treatment of type 2 diabetes mellitus (T2DM). Here, we aimed to evaluate the effect of duodenal reflux on glucose metabolism in T2DM. METHODS: A high-fat diet and low-dose streptozotocin (STZ) administration were used to induce T2DM in male rats, which were assigned to three experimental groups: sham operation (SO; n = 10), new duodenal-jejunal bypass (NDJB; n = 10), and new duodenal-jejunal bypass with a tube (NDJBT; n = 10)...
