The influence of shc proteins and aging on whole body energy expenditure and substrate utilization in mice. [PDF]

, 2012
While it has been proposed that Shc family of adaptor proteins may influence aging by regulating insulin signaling and energy metabolism, the overall impact of Shc proteins on whole body energy metabolism has yet to be elucidated.

Leaf litter identity rather than diversity shapes microbial functions and microarthropod abundance in tropical montane rainforests

Ecology and Evolution, 2021
In tropical forest ecosystems leaf litter from a large variety of species enters the decomposer system, however, the impact of leaf litter diversity on the abundance and activity of soil organisms during decomposition is little known. We investigated the

Lipid Oxidation Assessed by Indirect Calorimetry Predicts Metabolic Syndrome and Type 2 Diabetes

Frontiers in Endocrinology, 2019
Purpose: Diabetes has been linked to an impaired ability to oxidize fatty acids. Fat oxidation can be assessed clinically by a respiratory quotient measurement during fasting.

Metabolic Quotients of the Gravid Uterus of the Chronically Catheterized Guinea Pig [PDF]

Pediatric Research, 1985
The uptake of substrates by the pregnant uterus defines the "diet" of the uterus and conceptus. In order to determine the uterine substrate uptake, catheters were placed in the femoral artery and uterine veins of guinea pigs at 40-49 days gestation.

Instability of Metabolic Quotients Obtained from Tissue Cultures.

Experimental Biology and Medicine, 1960
SummaryMaximal growth of Earle's Strain L cells is obtained by using 15-20% horse serum with a medium containing 0.5% lactalbumin hydrolysate. Rate of lactate formation decreases as pH decreases but remains constant if the suspension is adequately buffered with bicarbonate.

The influence of malnutrition on the postprandial metabolic rate and respiratory quotient [PDF]

British Journal of Nutrition, 1972
1. Pre- and post-prandial metabolic rates were measured in twelve malnourished Jamaican infants.2. On admission to hospital, minimal increase in postprandial metabolic rate were found, whereas during the recovery phase when growth was rapid, inreases in postprandial metabolic rate of up to 38% occurred.3.

Soil microbial metabolism and invertase activity under crop rotation and no-tillage in North China

Plant, Soil and Environment, 2013
Soil samples were collected at both jointing and maturing stages of maize and wheat to compare the effects of 4-year no-tillage (NT) and conventional tillage (CT) on seasonal variations of microbial biomass carbon (C), metabolic quotient, and invertase ...
