Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Physiological Response to Feeding in Little Penguins [PDF]

, 2006
© 2006 by The University of Chicago.Specific dynamic action (SDA), the increase in metabolic rate above resting levels that accompanies the processes of digestion and assimilation of food, can form a substantial part of the daily energy budget of free ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Effect of dietary energy and weaning weight on nitrogen balance and energy metabolizability of piglets

Ciência Animal Brasileira, 2018
This study aimed to evaluate the effects of dietary metabolizable energy (ME; 3.40, 3.60, or 3.80 Mcal/kg) and weaning weight (WW; 4.5 ± 0.4 and 6.7 ± 0.5 kg) on nitrogen balance (NB) and gross energy metabolizability in weanling piglets.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Metabolizable Energy Nomenclature for Poultry Feedstuffs

Poultry Science, 1983
Abstract The use of the terms “apparent metabolizable energy” (AME) and “true metabolizable energy” (TME) is confusing and misleading. In proposing the “true” energy system, Harris (1966) confused the conceptual definition of metabolizable energy (ME) (Fraps, 1946) with the experimental techniques and resulting formulae for estimating its value ...

Bt176 corn in poultry nutrition: physiological characteristics and fate of recombinant plant DNA in chickens [PDF]

, 2017
A genetically modified Bt176 corn hybrid, which contains an insecticidal protein against the European corn borer, and its conventional, nonmodified counterpart were evaluated in 4 separate trials to verify substantial equivalence in feeding value and ...
