Unsuspected task for an old team: Succinate, fumarate and other Krebs cycle acids in metabolic remodeling

, 2014
Seventy years from the formalization of the Krebs cycle as the central metabolic turntable sustaining the cell respiratory process, key functions of several of its intermediates, especially succinate and fumarate, have been recently uncovered.

Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

Wildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Oral administration of Costa Rican guava (Psidium friedrichsthalianum) juice induces changes in urinary excretion of energy-related compounds in Wistar rats determined by 1H NMR

NFS Journal, 2020
Introduction: Psidium friedrichsthalianum fruits have in vitro antioxidant activity and their intake has been suggested to have potential health benefits; however, there is still no evidence on the potential in vivo effect of their consumption. Objective:

14C-labeled propionate metabolism in vivo and estimates of hepatic gluconeogenesis relative to Krebs cycle flux

, 1993
Purposes of this study were 1) to estimate in humans, using 14C-labeled propionate, the rate of hepatic gluconeogenesis relative to the rate of Krebs cycle flux; 2) to compare those rates with estimates previously made using [3-14C]lactate and [2-14C ...

The Greatest Show (Birds) on Earth: Public Presentations and Their Welfare Impacts on Zoo‐Housed Birds

Zoo Biology, EarlyView.
Birds involved in bird shows were compared against non‐show birds regarding show paticipation, behaviour, body score condiiton, and feather condition. Additionally, comparisons between on and off show days as well as before and after the show were made to investigate differences in behaviour and condition. Show birds demonstrated a closer to ideal body

DEVS modeling and simulation of the cellular metabolism by mitochondria

, 2005
: We present a simulation model for the metabolic pathways in the cells (namely, the Glycolysis and Krebs cycle), using the DEVS formalism and the CD++ tool.

Structure of ATP citrate lyase and the origin of citrate synthase in the Krebs cycle

, 2019
Across different kingdoms of life, ATP citrate lyase (ACLY, also known as ACL) catalyses the ATP-dependent and coenzyme A (CoA)-dependent conversion of citrate, a metabolic product of the Krebs cycle, to oxaloacetate and the high-energy biosynthetic ...

Hotter, faster, sicker? Warming shifts the cost of infection from individuals to populations

Journal of Animal Ecology, EarlyView.
This study examines how temperature alters disease impacts across biological scales in a host–pathogen system. We found infected hosts appear healthiest at warm temperatures, yet populations suffer most. This suggests climate warming may intensify disease impacts for populations in ways traditional individual‐level virulence metrics fail to predict ...

Krebs cycle anions in metabolic acidosis.

Critical care (London, England), 2005
For many years it has been apparent from estimates of the anion gap and the strong ion gap that anions of unknown identity can be generated in sepsis and shock states. Evidence is emerging that at least some of these are intermediates of the citric acid cycle.
