The kidney is a typical organ undergoing age and injury. Hyperoside is reported to be useful for preventing aging induced by D-galactose (D-gal). However, therapeutic mechanisms remain unclear. We thereby aimed to verify whether hyperoside, compared to vitamin E (VE), could alleviate renal aging and injury by regulating autophagic activity and its related signaling pathways. , rats were administered with either hyperoside or VE after renal aging modeling induced by D-gal. Changes in renal aging and injury markers, autophagic activity and AMPK-ULK1 signaling pathway in the kidneys were analysed. , the NRK-52E cells exposed to D-gal were used to investigate regulative actions of hyperoside and VE on cell viability, renal tubular cellular aging markers, autophagic activity and its related signaling pathways by histomorphometry, immunohistochemistry, immunofluorescence, lentiviral transfection and Western blot. Aging and injury in the kidneys and renal tubular cells induced by D-gal were ameliorated by hyperoside and VE. Hyperoside and VE inhibited autophagic activity through mTOR-independent and AMPK-ULK1 signaling pathways. Hyperoside, as a component of phytomedicine similar to VE, attenuated renal aging and injury induced by D-gal via inhibiting AMPK-ULK1-mediated autophagy. This study provides the first evidence that hyperoside contributes to the prevention of age-associated renal injury.

Sjögren's syndrome (SS) is an autoimmune disease and its management is palliative. There is no specific dietary protocol for SS patients. A gluten-free diet has been tested in SS patients with celiac disease (CD) and indicated modest improvements.

Background: Various factors contribute to postoperative delirium (POD) in elderly patients undergoing hip fracture surgeries. Sarcopenia was defined as the progressive loss of skeletal muscle mass and strength associated with aging. The aim of this study was to explore the prevalence of POD and sarcopenia in geriatric patients undergoing hip fracture surgeries and to investigate the correlation between preoperative sarcopenia and POD.

Study Purpose: Evidence on the effects of sarcopenic obesity (SO) on incident chronic kidney disease (CKD) and rapid kidney function decline (RKFD) in the Chinese population is limited. This study aimed to prospectively examine the associations of SO with incident CKD and RKFD among middle-aged and older Chinese adults.
Study Design And Methods: This prospective cohort study utilized data from the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative longitudinal study of Chinese adults aged 45 and older.

Lipocalin-2 (LCN2), a hormone produced by adipocytes, osteoblasts, and renal tubular cells, is implicated in age-related diseases, including cardio-metabolic disease. To understand the role LCN2 may play in pathological states, we first need to elucidate the relationship between circulating LCN2 with indices of cardio-metabolic health during "normal" aging. This study examined the relationship between serum levels of LCN2, age, and cardio-metabolic measures across the adult lifespan in males and females.
