The study applied UHPLC‑Q‑TOF‑MS/MS to profile resin glycosides (RGs) in leaves of nine sweet‑potato cultivars, identifying 128 distinct RGs. Multivariate analysis linked four pentasaccharide RGs—featuring 2‑methylbutyric and dodecanoic acid side chains—to potent pancreatic lipase inhibition. Xushu 32 and Blackheart extracts showed the highest Orlistat‑equivalent activity, while hydroponic cultivation of Beniazuma increased inhibitory RG content. The findings clarify structure‑activity relationships and highlight cultivar‑ and environment‑driven variation in anti‑obesity potential.
A retrospective matched cohort study of 2,482 dementia patients found that serum zinc deficiency (<70 µg/dL) was linked to a 54% higher risk of 1‑year all‑cause mortality. Deficient patients also experienced significantly increased rates of sepsis, ICU admission, urinary tract infection,...
