Associations of chinese-modified MIND diet with low muscle mass and physical performance among old adults in china: findings from the CLHLS 2018 national survey

3 weeks 3 days ago
CONCLUSION: Greater adherence to the cMIND dietary pattern is independently associated with lower probability of LMM and better physical performance among older Chinese adults. These findings suggest potential benefits of promoting MIND diet principles for maintaining musculoskeletal health in aging populations.

Selective peroxynitrite-mediated protein nitration catalyzed by glyoxalase domain containing protein 4

3 weeks 3 days ago
Tyrosine nitration alters the structure, function, and cellular localization of proteins and is implicated in the pathology of multiple diseases [G. Ferrer-Sueta et al., Chem. Rev. 118, 1338-1408 (2018), H. Ischiropoulos, Arch. Biochem. Biophys. 356, 1-11 (1998), I. Griswold-Prenner et al., J. Biol. Chem. 299, 105038-10554 (2023)]. Although protein nitration is assumed to proceed via nonspecific chemical mechanisms, it is highly selective, suggesting the possibility of enzymatic catalysis. Here,...

PTP1B inhibition promotes microglial phagocytosis in Alzheimer's disease models by enhancing SYK signaling

3 weeks 3 days ago
Amyloid β (Aβ) accumulation is a hallmark of Alzheimer's disease (AD). Emerging evidence suggests that impaired microglial Aβ phagocytosis is a key feature in AD, highlighting the therapeutic potential of enhancing this innate immune function. Here, we demonstrate that genetic deletion or pharmacological inhibition of protein tyrosine phosphatase 1B (PTP1B) ameliorated memory deficits and reduced Aβ burden in APP/PS1 mice. Moreover, we show that PTP1B was highly expressed in microglia, and its...
