Journal of the Science of Food and Agriculture, EarlyView.Abstract Selenium (Se) is essential for human and animal health and nutritional status. As humans cannot produce Se, it must be obtained from the diet. Adequate Se supplementation improves innate immunity, increases antioxidant capacity and helps prevent various disorders.

Recent Developments in the Optical Control of Adrenergic Signaling
Medicinal Research Reviews, EarlyView.ABSTRACT Adrenoceptors (ARs) play a vital role in various physiological processes and are key therapeutic targets. The advent of optical control techniques, including optogenetics and photopharmacology, offers the potential to modulate AR signaling with precise temporal and spatial resolution. In this review, we summarize the latest advancements in the

Archimedean superrigidity of solvable S-arithmetic groups [PDF]
arXiv, 1996 Let $\Ga$ be a connected, solvable linear algebraic group over a number field~$K$, let $S$ be a finite set of places of~$K$ that contains all the infinite places, and let $\theints$ be the ring of $S$-integers of~$K$. We define a certain closed subgroup~$\GOS$ of $\Ga_S = \prod_{v \in S} \Ga_{K_v}$ that contains $\Ga_{\theints}$, and prove that $\Ga_ ...

Aging Cell, EarlyView.Our study reveals that overactivation of both mTOR complexes through mLST8 in RPE cells triggers AMD‐like pathology and cellular dysfunction. This finding highlights the critical role of balanced mTOR signaling in retinal health and suggests that targeting both complexes could be therapeutic for AMD treatment.

Microscopy and spectroscopy approaches to study GPCR structure and function
British Journal of Pharmacology, EarlyView.Abstract The GPCR signalling cascade is a key pathway responsible for the signal transduction of a multitude of physical and chemical stimuli, including light, odorants, neurotransmitters and hormones. Understanding the structural and functional properties of the GPCR cascade requires direct observation of signalling processes in high spatial and ...
