TL;DR: The data suggest that muscle quantity and muscle quality assessed from EI measured using computer-aided gray-scale analysis independently contribute to muscle strength in middle-aged and elderly persons.

TL;DR: Investigating whether muscle quality based on EI is associated with muscle strength independently of muscle size for elderly men indicated that aging-related changes in muscle quality contribute to diminishing muscle strength.

TL;DR: In this paper, four monoclonal antibodies were raised against H6H purified from cultured roots of Hyoscyamus niger, and the results showed that the antibody was able to identify 38-40kDa proteins from six different scopolamine-producing plant species in Western blot analysis after SDS-polyacrylamide gel electrophoresis.

TL;DR: The older adults showed significantly higher coactivation than the young adults during the tasks of standing, functional reach, functional stability boundary (forward), and gait, suggesting increased muscle coactivation could be a necessary change to compensate for a deterioration in postural control accompanying healthy aging.

TL;DR: In this article, the authors analyzed a large, diverse database of total expenditure measured by the doubly labeled water method for males and females aged 8 days to 95 years and found that fat-free mass-adjusted expenditure accelerates rapidly in neonates to ~50% above adult values at ~1 year; declines slowly to adult levels by ~20 years; remains stable in adulthood (20 to 60 years), even during pregnancy; then declines in older adults.
