Mineral metabolism in the bones of 1- and 3-month rats reacts to a different extent to cutting the lower alveolar nerve. After deafferentation of the lower jaw, the decrease in the intensity of incorporation of the intraperitoneally injected [3-14C]-citrate and [35S]-sulphate in the bones is more significant in 1-month animals as compared to that in older ones. Deafferentation increased utilization of Na2H32PO4 and 45CaCl2 in the bones of younger rats, but decreased incorporation of 32P and remained unchanged incorporation of 45Ca in 3-month animals.

Background: In skilled nursing facilities (SNFs), i-STRONGER is a novel, high-intensity resistance training approach that incorporates progressive resistance training to promote greater improvements in patient function compared to usual care. To inform large-scale expansion of i-STRONGER as standard-of-care in SNFs, this mixed-methods study assessed rehabilitation providers' perceptions of i-STRONGER and purported needs for its adoption.
Methods: Forty-three rehabilitation providers participated in an 18-week, interactive i-STRONGER training program.

Background: Osteoporosis is a common age-related disease with disabling consequences, the early diagnosis of which is difficult due to its long and hidden course, which often leads to diagnosis only after a fracture. In this regard, great expectations are placed on advanced developments in machine learning technologies aimed at predicting osteoporosis at an early stage of development, including the use of large data sets containing information on genetic and clinical predictors of the disease. Nevertheless, the inclusion of DNA markers in prediction models is fraught with a number of difficulties due to the complex polygenic and heterogeneous nature of the disease.

Objective: To propose Deep-RPD-Net, a 3-dimensional deep learning network with semisupervised learning (SSL) for the detection of reticular pseudodrusen (RPD) on spectral-domain OCT scans, explain its decision-making, and compare it with baseline methods.
Design: Deep learning model development.
Participants: Three hundred fifteen participants from the Age-Related Eye Disease Study 2 Ancillary OCT Study (AREDS2) and 161 participants from the Dark Adaptation in Age-related Macular Degeneration Study (DAAMD).

Inflammaging, a state of chronic low-grade inflammation associated with aging, has been linked to the development and progression of various disorders. Cellular senescence, a state of irreversible growth arrest, is another characteristic of aging that contributes to the pathogenesis of cardiovascular pathology. Senescent cells accumulate in tissues over time and secrete many inflammatory mediators, further exacerbating the inflammatory environment.

Purpose: To utilize optical coherence tomography (OCT) and SS-OCT angiography (SS-OCTA) for quantifying morphological changes seen in eyes with recalcitrant neovascular age-related macular degeneration (nAMD) transitioned to intravitreal faricimab injections during the manufacturer's recommended induction phase of treatment.
Methods: Fifty-four treatment-recalcitrant patients (60 eyes) were recruited. OCT and SS-OCTA images were obtained at 0 and 3 months.
