Context The B islets isolated from 3-5 day old chick respond well to glucose challenge in a similar fashion to those isolated from mouse pancreas. Objective To compare insulin secretory response of chick B islets with that of human Islet Equivalents (hIEqs) generated from stem cells. Methods Human Umbilical Cord Mesenchymal Stem Cells (UC-MSCs) were differentiated into hIEqs employing three ste...

The intracellular sodium concentration reported for young, embryonic chick hearts is extremely high and decreases progressively throughout the embryonic period, reaching a value of 43 mM immediately before hatching. This observation suggested that the ionic basis for excitation in embryonic chick heart may differ from that responsible for electrical activity of the adult organ. This hypothesis ...

While animal experiments have contributed much to our understanding of the mechanisms of Alzheimer's disease (AD), their value in predicting the effectiveness of treatment strategies in clinical trials has remained controversial. The disparity between the results obtained in animal models and clinical trials may in part be explained by limitations of the models and species-specific differences....

Ostrich chick mortality was studied in 2522 chicks that were hatched artificially during the 1999/2000 breeding season. High levels of mortality were observed, with 1978 (78.4 %) of these chicks dying before 90 days after hatching. A total of 46.7 % (1,177) of these chicks died before 28 days of age, and a further 30.7% (801) died between 28 and 90 days post-hatching. Chick mortality to 28 days...

this experiment was carried out to study effect of supplementary multi enzyme (0, 4 gr per 100 kg of diet) to corn-soybean meal based diets with different levels of tomato pomace (tp, 0, 2, 4, 6 and 8 %, respectively) on chick performance and carcass traits. four hundred and eighty 480 day-old chicks (ross-308) were employed [four replicates (n=20)] in a completely randomized experimental desig...

Twelve-day-old embryonic chick mandibles were cultured in vitro for 6 days. Measurements of the weights of the explants, their mineral and protein components, and the EDTA-extractable proteins established that bone tissue synthesizes O-phosphoserine- and O-phosphothreonine-containing phosphoproteins which are similar to those present in embryonic and postnatal chicken bone matrix. The synthesis...

The purpose was to determine the comparison of giving herbal herbs through feed and drinking water productivities broilers. research took place in Closed House Cage Animal Science Laboratory, Faculty Agriculture Science, University Muhammadiyah Malang, East Java, Indonesia. material Day Old Chick (DOC) broilers by number 200 water. treatment divided into two types as follows: Herbs (TA) (TB). T...

The intestine of the newly hatched chick is immature at hatch. Yeast contains nucleotides and β-glucans that enhance intestinal development and chick growth. Accordingly, a 14-d experiment was conducted to evaluate the efficacy of a novel yeast product and bacitracin methylene disalicylate in enhancing early growth and intestinal maturation in chicks obtained from young (26-27 wk old) and old (...

The concentration of mercury (Hg) in eggs that causes reduced hatching success is regarded as a critical end point for Hg toxicity in birds. However, incorporating effects of in ovo mercury exposure on chick health and survival could improve risk assessment. We developed equations to predict Hg in eggs using Hg in chick down feathers, and vice versa, by assessing the relationship between Hg in ...
