Is the rate of metabolic ageing and survival determined by Basal metabolic rate in the zebra finch? [PDF]

open access: yesPLoS ONE, 2014
The relationship between energy metabolism and ageing is of great interest because aerobic metabolism is the primary source of reactive oxygen species which is believed to be of major importance in the ageing process. We conducted a longitudinal study on

Environment, migratory tendency, phylogeny and basal metabolic rate in birds. [PDF]

open access: yesPLoS ONE, 2008
Basal metabolic rate (BMR) represents the minimum maintenance energy requirement of an endotherm and has far-reaching consequences for interactions between animals and their environments.

TT Mutant Homozygote of Is a Key Factor for Increasing Basal Metabolic Rate and Resting Metabolic Rate in Korean Elementary School Children [PDF]

open access: yesGenomics & Informatics, 2013
We investigated the contribution of genetic variations of KLF5 to basal metabolic rate (BMR) and resting metabolic rate (RMR) and the inhibition of obesity in Korean children. A variation of KLF5 (rs3782933) was genotyped in 62 Korean children.

Perioperative metabolism in patients with secondary hyperparathyroidism and methods of its correction

open access: yesPatologìâ, 2021
It is important to study changes in metabolism in patients with secondary hyperparathyroidism (SHPT) during parathyroid surgical interventions (PTSI), as well as to search for ways to correct them. Aim.

The mitochondrial Na+/Ca2+ exchanger upregulates glucose dependent Ca2+ signalling linked to insulin secretion. [PDF]

open access: yes, 2012
Mitochondria mediate dual metabolic and Ca(2+) shuttling activities. While the former is required for Ca(2+) signalling linked to insulin secretion, the role of the latter in β cell function has not been well understood, primarily because the molecular ...

A Sceptics View: “Kleiber’s Law” or the “3/4 Rule” is neither a Law nor a Rule but Rather an Empirical Approximation

open access: yesSystems, 2014
Early studies showed the metabolic rate (MR) of different-sized animals was not directly related to body mass. The initial explanation of this difference, the “surface law”, was replaced by the suggestion that MR be expressed relative to massn, where the

Validação de equações de predição da taxa metabólica basal em mulheres residentes em Porto Alegre, RS, Brasil Validation of predictive equations of basal metabolic rate of women living in Southern Brazil

open access: yesRevista de Saúde Pública, 2001
OBJETIVO: Medir a taxa metabólica basal em mulheres de 20 a 40 anos, não-gestantes ou lactantes, e comparar o valor medido com os valores de taxa metabólica basal estimados por equações de predição.

Fluctuating selection on basal metabolic rate [PDF]

open access: yesEcology and Evolution, 2016
AbstractBMR (Basal metabolic rate) is an important trait in animal life history as it represents a significant part of animal energy budgets. BMR has also been shown to be positively related to sustainable work rate and maximal thermoregulatory capacity.
