BACKGROUND Regular exercise is associated with a reduction in cardiovascular risk, but the precise mechanisms responsible are unknown. The aim of the current study was to examine the relationship between regular exercise, aortic stiffness, and wave reflections, and to determine whether this relationship differs by age. METHODS Younger (<30 years) and older (>50 years) individuals, who were ei...

Renal function was studied in mice of different ages. In metabolic cage experiments, the renal electrolyte excretion was similar in young (n = 8; 5- to 7-wk-old) and adult (n = 6; 20- to 22-wk-old) CD-1 (ICR) BR mice, whereas spontaneous drinking volume and urinary flow rate were significantly higher in the adult compared with the young mice. Subsequently, the renal functional reserve was inves...

[Purpose] Poor posture in children and adolescents is a well-known problem. Therefore, early detection of incorrect posture is important. Photometric posture analysis is a cost-efficient and easy method, but needs reliable reference values. As children's posture changes as they grow, the assessment needs to be age-specific. This study aimed to investigate the development of both one-dimensional...

BACKGROUND Red blood cell distribution width (RDW) was recently shown to be age-dependent when using Sysmex XE-2100 hematology analyzers. As measuring RDW is subject to technology, we have investigated if this relation also exists when using a different hematology analyzer, Abbott CELL-DYN Sapphire. In addition, as RDW is generally expressed relative to mean red blood cell volume (MCV), we have...

Autofluorescence (lambda = 530 nm) of the human lens was determined as a function of age by fluorophotometry in insulin-dependent diabetics and in healthy controls. Statistical analysis revealed a significant linear age dependency for both groups (7.98 ng eq X ml-1 y-1 for diabetic patients, P less than 0.001 and 6.36 ng eq X ml-1 y-1 for healthy controls, P less than 0.001) and a significant d...

This paper examines the effects of age dependency ratio (the young age, old-age and overall age) urbanization on renewable non-renewable energy consumption in Brazil, India, China, South Africa, considering panel data from 1990 to 2019. We control economic growth foreign direct investment inflows as key factors demand function using Stochastic Impacts by Regression Population, Affluence Technol...
