Navigating motherhood: biological and landscape factors affecting postpartum movement in white-tailed deer.

Background: Population growth and management in cervid species is dependent on reproductive ecology and factors influencing juvenile survival. Aspects of the female's movement behavior likely affect juvenile survival and movement patterns of pregnant and lactating females differ from non-pregnant or non-lactating females. Explanations for these differing movement patterns include change in nutritional demands for the female, isolation during parturition, and predator avoidance.

The role of maximal inspiratory pressure on functional performance in adults with heart failure.

Background: Exercise intolerance is common among adults with heart failure (HF) and is a strong prognostic indicator. We examined maximal inspiratory pressure (MIP) as an indicator of maximal and submaximal exercise capacity in older HF patients.

Methods: Fifty-one patients age ≥ 50 years with HF underwent MIP testing via the PrO device.

Loss of NAMPT and SIRT2 but not SIRT1 attenuate GLO1 expression and activity in human skeletal muscle.

Glyoxalase I (GLO1) is the primary enzyme for detoxification of the reactive dicarbonyl methylglyoxal (MG). Loss of GLO1 promotes accumulation of MG resulting in a recapitulation of diabetic phenotypes. We previously demonstrated attenuated GLO1 protein in skeletal muscle from individuals with type 2 diabetes (T2D).

Body Composition, Falls, and Freezing of Gait in Parkinson's Disease: Gender-Specific Effects.

Background: Postural instability and gait difficulties (PIGD) are a significant cause of mobility loss and lower quality of life in Parkinson's disease (PD). When PD progresses, patients may experience falls and freezing of gait (FoG) resulting in fear of falling and increasing sedentariness. Sedentary behavior results in sarcopenia associated with other changes in body composition, especially in older patients becoming frail.
