Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Prognostic Impact of European LeukemiaNet Genetic Risk Stratification System in Adult Patients With Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
This study aimed to evaluate the prognostic value of ELN2017 in predicting survival outcomes and to assess the impact of clinical and molecular factors such as age, FLT3 and NPM1 mutations, and allogeneic hematopoietic stem cell transplantation (allo‐HSCT).

The Dynamics of Neighborhood Age Composition [PDF]

open access: possibleEnvironment and Planning A: Economy and Space, 1998
In this paper we investigate the changing demography of neighborhoods. We focus upon the dynamics of the age structure of neighborhoods, paying particular attention to the roles of (a) the magnitude of mobility and (b) the age composition of in-migrants and out-migrants.

AG-COMPOSITES WITH ANTIMICROBIAL PROPERTIES

AIP Conference Proceedings, 2008
Polymer composites with antimicrobial properties were prepared by mixing plasticised poly(vinyl chloride) (PVC) pellets with silver nanoparticles and silver zeolite in the amount of 8 wt% and 10 wt%, respectively. Thermal and mechanical properties of PVC composites were obtained by tensile and calorimetric (TGA and DSC) measurements.

Body Composition and Aging

2012
Body composition in older adults can be assessed using simple, convenient but less precise anthropometric methods to assess (regional) body fat and skeletal muscle, or more elaborate, precise and costly methods such as computed tomography and magnetic resonance imaging.

Body Composition and Aging

Nutrition Reviews, 2009
he changes in composition of the aging T human body is of both gerontologic and geriatric interest and reflects genetic factors and environmental factors such as physical activity, nutrition, and disease, as well as the normal aging processes. In the study of normal aging, that is, aging per se, long-term trends in body compartments are important.

Environmental Aging of Epoxy Composites

1983
Fiber reinforced plastics (FRP) are increasingly utilized for structural application where their long-term properties are of primary importance. The strength enhancement and resistence to fracture which occurs when one combines high-strength fiber with low strength, low modulus polymer matrix, depends to a great extent on the polymer-filler interfaces.

Aging and Changes in Body Composition

2017
As we grow older changes in body composition occur. These changes include a loss of lean body mass (LBM), bone mass, body water, and a relative increase of fat mass. In view of these changes and acknowledging demographic trends, elder people are facing a growing burden of health-compromising levels of their weight, including underweight, overweight ...

Anorexia, body composition, and ageing

Current Opinion in Clinical Nutrition and Metabolic Care, 2001
Over the lifespan there is a decline in food intake. This has been termed the physiological anorexia of aging. It has many causes, including alterations in the gastrointestinal satiating system, the effect of elevated leptin levels, especially in men, and a variety of changes in central nervous system neurotransmitters.
