Mathematical modelling in animal nutrition: a centenary review [PDF]

, 2008
A centenary review presents an opportunity to ponder over the processes of concept development and give thought to future directions. The current review aims to ascertain the ontogeny of current concepts, underline the connection between ideas and people

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 ...

Predicting post-absorptive protein and amino acid metabolism

Revista Brasileira de Zootecnia, 2018
Sustainable production of adequate quantities of food to support a growing human population is a worldwide goal. Under current feeding conditions in the United States, dairy cattle convert dietary nitrogen to milk nitrogen with 25% efficiency.

Diet Choice by Dairy Cows. 2. Selection for Metabolizable Protein or for Ruminally Degradable Protein?

Journal of Dairy Science, 1998
Diet choice, expressed as grams of high protein feed selected per kilogram of intake, was measured for lactating cows with ad libitum access to two feeds. First, cows were given a choice between a low protein feed and a high protein feed for 9 wk while feeds were alternated between feeders.

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.

Nutritional value of high fiber co-products from the copra, palm kernel, and rice industries in diets fed to pigs. [PDF]

, 2015
High fiber co-products from the copra and palm kernel industries are by-products of the production of coconut oil and palm kernel oil. The co-products include copra meal, copra expellers, palm kernel meal, and palm kernel expellers. All 4 ingredients are

Interaction of Dietary Metabolizable Energy and Protein in Laying Hen Diets

Poultry Science, 1980
Abstract Single Comb White Leghorn pullets, housed in colony cages, were employed in this study to investigate the effects of dietary protein and metabolizable energy (ME) levels on performance. The treatments consisted of dietary ME levels of 2.42, 2.64, 2.86, and 3.08 kcal/g of diet with each fed in diets containing 14, 16 and 18% protein to ...

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Evaluation of phosphorus, calcium, and magnesium content in commercially available foods formulated for healthy cats. [PDF]

, 2020
BackgroundHigh dietary phosphorus (P) and low calcium-to-phosphorus ratio (Ca:P) are associated with kidney damage in cats. There are no established guidelines for dietary P maximum for cats.ObjectivesTo quantify crude protein, P, Ca, and magnesium (Mg ...
