Facilitation of Ca 3.2 channel gating in pain pathways reveals a novel mechanism of serum-induced hyperalgesia.

The Ca 3.2 isoform of T-type voltage-gated calcium channels plays a crucial role in regulating the excitability of nociceptive neurons; the endogenous molecules that modulate its activity, however, remain poorly understood. Here, we used serum proteomics and patch-clamp physiology to discover a novel peptide albumin (1-26) that facilitates channel gating by chelating trace metals that tonically inhibit Ca 3.

Quality measures for the care of patients with insomnia: 2024 update after measure maintenance.

Insomnia is highly prevalent and is one of the most common sleep disorders amongst adults and children in the US. The American Academy of Sleep Medicine (AASM) convened the Quality Measures Task Force (Task Force) to perform maintenance on this quality measure set, developed to optimize management and care for patients with insomnia, as the measure set was originally developed and published in 2015. The Task Force reviewed the current medical literature, including updated clinical practice guidelines and systematic literature reviews, existing quality measures, and performance data highlighting gaps or variations in care since implementation of the original quality measure set to inform any potential revisions to the quality measures.

Exaptation of ancestral cell-identity networks enables C photosynthesis.

C photosynthesis is used by the most productive plants on the planet, and compared with the ancestral C pathway, it confers a 50% increase in efficiency. In more than 60 C lineages, CO fixation is compartmentalized between tissues, and bundle-sheath cells become photosynthetically activated. How the bundle sheath acquires this alternate identity that allows efficient photosynthesis is unclear.

A cynomolgus monkey urinary tract infection model confirms efficacy of new FimH vaccine candidates.

The increase in urinary tract infections (UTI) caused by antibiotic-resistant requires the development of new therapeutic agents and prophylactic vaccines. To evaluate the efficacy of new lead candidates, we implemented a cynomolgus macaque UTI challenge model that mimics human uncomplicated cystitis in response to transurethral challenge with a multidrug-resistant (MDR) serotype O25b ST131 isolate. fimbrial adhesin FimH and O-antigens are separately under clinical evaluation by others as vaccine candidates to prevent UTI and invasive urosepsis disease, respectively.

Quality measure for screening for adult obstructive sleep apnea by primary care providers: 2024 update after measure maintenance.

Unlabelled: Obstructive sleep apnea (OSA) is a prevalent respiratory sleep disorder that, when left undiagnosed or untreated, can lead to adverse outcomes. There continue to be gaps and variations in screening adults who are high risk for OSA in the primary care setting, leading to many adults in the United States going undiagnosed. As a part of the ongoing American Academy of Sleep Medicine quality measure maintenance initiative, the American Academy of Sleep Medicine Quality Measures Task Force reviewed the original screening for adult OSA by primary care physicians quality measure.
