RNA Helicase DDX21 Controls CD4+ T Cell Proliferation and Promotes Inflammatory Bowel Disease via Translational Control

open access: yesAdvanced Science, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD) is characterized by dysregulated T cell responses. RNA helicases, including DExD‐box helicase 21 (DDX21), are pivotal in RNA metabolism, but their role in T cell‐mediated pathology during IBD remains unclear. Here, we demonstrate that DDX21 expression in CD4+ T cells correlates with cell cycle and translation ...

Apparent chitin digestibility in penaeid shrimp

Aquaculture, 1993
Abstract Apparent digestibility of chitin was investigated in three species of penaeid shrimp, Penaeus vannamei, P. setiferus and P. duorarum , fed diets containing three levels of chitin (1, 2 and 4%). Fecal analysis for N-acetyl-glucosamine (NAG) indicated higher chitin levels in the diet resulted in increased levels of NAG in the feces ...

APPARENT DIGESTIBILITY OF MACRONUTRIENTS IN CAPTIVE BABIRUSA (BABYROUSA BABYRUSSA)

Journal of Zoo and Wildlife Medicine, 2000
The apparent digestibilities of macronutrients by babirusa (Babyrousa babyrussa) were measured. Three group-housed captive babirusa were fed a diet of pelleted feed, boiled potatoes, grains, vegetables, and fruits. To determine reproducibility of the results, two digestibility trials were conducted 5 wk apart.

Comparison of the apparent ileal calcium digestibility of limestone in broilers and layers

British Poultry Science, 2021
1. The apparent ileal calcium (Ca) digestibility coefficients of two limestone sources in growing broilers and layers were determined in two separate experiments.2. In each experiment, two maize-based diets were developed with two limestone sources (A, experiment 1 and B, experiment 2) to contain either 8.0 g/kg Ca for broilers or 40 g/kg Ca for layers.

THE INFLUENCE OF APPARENT DIGESTIBLE ENERGY AND APPARENT DIGESTIBLE NITROGEN IN THE DIET ON WEIGHT GAIN, FEED CONSUMPTION, AND NITROGEN RETENTION OF GROWING MINK

Canadian Journal of Biochemistry and Physiology, 1962
The influences of the apparent digestible energy (A.D.E.) and the apparent digestible nitrogen (A.D.N.) content of the diet on the food consumption, nitrogen retention, and growth of mink from weaning to pelting age have been determined. It was demonstrated with diets containing from 3.33 to 4.21 Cal of A.D.E. and 26.14 to 39.76 mg of A.D.N.

Analysis of Digestion Data: Apparent and True Digestibilities of Foods Eaten by Beavers

American Midland Naturalist, 1994
A13STRACT.-Digestibility data generally are analyzed as ratio variables, but to be useful this method requires that animals consume large quantities of food. If little is eaten, as may occur with novel or unpalatable foods, apparent digestibility estimates can be seriously biased and statistical analyses may suffer from very low power to detect ...

Apparent digestibility of invertebrate biomasses by rainbow trout

Aquaculture, 1985
Abstract This study was aimed at comparing the apparent digestibility of chironomid larvae, daphnid, and gammarid biomasses by rainbow trout and characterizing the amino acid profiles of each of these food sources. Rainbow trout were fed twice daily on a reference diet (91.5% fish meal) and three other diets containing 30% of chironomids, daphnids or

An apparent “specificity” in digestion of living gastric mucosa in rats

Gastroenterology, 1956
Summary Inbred rats were used in experiments designed to discover if some sort ofspecificity was involved in the usual failure of the stomach to digest itself. It was found that, under the conditions imposed, normal glandular mucosa in each strain is resistant to its own secretion but each is vulnerable to the secretion of a different rat. The results

Apparent Digestibility Coefficients of Carbohydrates for White Sturgeon

The Progressive Fish-Culturist, 1995
Abstract Apparent digestibility coefficients (ADCs) were determined for white sturgeons (Acipenser transmontanus) fed purified diets containing different carbohydrates. White sturgeons were fed, at a rate of 1.0% body weight!d, diets containing one of nine carbohydrates, and feces were collected by manual stripping following a 2-week feeding period ...

The effect of crude fibre on apparent digestibility and digestible energy content of extruded dog foods

Journal of Animal Physiology and Animal Nutrition, 2001
The apparent digestibility of nutrients and energy of 38 commercial dry extruded dog foods was measured using six adult (2 to 3 year‐old) female Beagles. Diets contained [in g/kg dry matter (DM)]: 164–360 crude protein (CP); 79–261 ether extracts (EE); 8–33 crude fibre (CF) and 318–585 nitrogen free extracts (NFE).
