Structural insights into mechanisms of zinc scavenging by the zincophore Pra1.

causes more than 400,000 life-threatening, and half a billion mucosal infections annually. In response to infection, the host limits availability of essential micronutrients, including zinc, to restrict growth of the invading pathogen. As assimilation of zinc is essential for pathogenicity, its limitation induces the secretion of the zincophore protein Pra1 to scavenge zinc from the host.

Incentives for smoking cessation.

Background: Financial incentives (money, vouchers, or self-deposits) can be used to positively reinforce smoking cessation. They may be used as one-off rewards, or in various schedules to reward steps towards sustained smoking abstinence (known as contingency management). They have been used in workplaces, clinics, hospitals, and community settings, and to target particular populations.

Management of operating theatre ambient temperature for major burn patients in a state-wide adult burns centre.

Introduction: The aim of this study was to investigate the efficacy of limiting increases in theatre ambient temperature to 27°C to prevent intraoperative patient hypothermia.

Methods: This single-centre, comparative cohort clinical study investigated the management of theatre ambient temperatures involving patients with ≥ 20 % TBSA burn injuries at Victorian Adult Burns Service (Melbourne, Australia). Data from the intervention group (August 2021 - February 2023, theatre ambient temperature increase limited to 27°C) was compared with a historical cohort (August 2019 - August 2021).

Leucine Aminopeptidase LyLAP enables lysosomal degradation of membrane proteins.

Unlabelled: Proteolysis of hydrophobic helices is required for complete breakdown of every transmembrane protein trafficked to the lysosome and sustains high rates of endocytosis. However, the lysosomal mechanisms for degrading hydrophobic domains remain unknown. Combining lysosomal proteomics with functional genomic data mining, we identify Lysosomal Leucine Aminopeptidase (LyLAP; formerly Phospholipase B Domain-Containing 1) as the hydrolase most tightly associated with elevated endocytic activity.
