Melatonin relations with respiratory quotient weaken on acute exposure to high altitude
(Frontiers Media, 2018-06-29)
High altitude (HA) exposure may affect human health and performance by involving the body timing system. Daily variations of melatonin may disrupt by HA exposure, thereby possibly affecting its relations with a metabolic ...
TNF-alpha acts in the hypothalamus inhibiting food intake and increasing the respiratory quotient - Effects on leptin and insulin signaling pathways
(Elsevier B.V., 2007-05-01)
Acting in the hypothalamus, tumor necrosis factor-alpha (TNF-alpha) produces a potent anorexigenic effect. However, the molecular mechanisms involved in this phenomenon are poorly characterized. In this study, we investigate ...
Why are nutritionally stunted children at increased risk of obesity? Studies of metabolic rate and fat oxidation in shantytown children from Sao Paulo, Brazil
(Amer Soc Clinical Nutrition, 2000-09-01)
Background: Previous research suggested that nutritionally stunted children may have increased risk of obesity, but little is known about potential underlying mechanisms.Objective: We sought to test the hypothesis that ...
Ratio of CO2 and O-2 as index for categorising soil biological activity in sugarcane areas under contrasting straw management regimes
(Csiro Publishing, 2018-01-01)
This study was developed in a sugarcane area under contrasting management regimes defined by mechanical green harvesting (GH) and burning harvesting (BH) to test the hypotheses that the ratio of carbon dioxide (CO2) and ...
Association between adipose tissue characteristics and metabolic flexibility in humans: a systematic review
(Frontiers Media, 2021)
Adipose tissue total amount, distribution, and phenotype influence metabolic health.
This may be partially mediated by the metabolic effects that these adipose tissue
characteristics exert on the nearby and distant ...
