From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Ideal Protein Based Diets for Turkeys
International Journal of Poultry Science, 2010 Ideal protein as a concept has been around for a number of years. The data necessary to formulate an ideal protein based diet include amino acid digestibility of major feedstuffs, a working estimate of an ideal protein for turkeys, a workable low protein diet for determining amino acid requirements via titration and requirement data for the limiting ...

Concept of Ideal Protein in Formulation of Aquaculture Feeds
EDIS, 2007 FA-144, a 3-page fact sheet by Richard D. Miles and Frank A. Chapman, discusses the concept of using proteins meeting the digestible amino acids requirement of the fish using lysine as a reference, and the problem with using feed with an excess of protein. Published by the UF Department of Fisheries and Aquatic Sciences, March 2007.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Determination of digestible isoleucine: lysine ratio in diets for laying hens aged 42-58 weeks
Revista Brasileira de Zootecnia, 2012 Two hundred and fifty-two Hy-Line W36 laying hens were allotted in a completely randomized design with 6 treatments, 7 replicates and 6 hens per experimental unit in order to determine the ideal ratio of isoleucine (Ile) in relation to lysine (Lys) to ...
