Hatching egg and newly hatched chick yolk sac total IgY content at 3 broiler breeder flock ages.

open access: yesPoultry Science, 2012
During the first week of the posthatching period, before the immune system is mature enough to produce its own B lymphocytes, a chick's humoral immunity depends on maternal antibodies (IgY) received from the egg yolk. During incubation and after hatching,

Organ‐on‐Chip: The Future of Nutrition Research in a One Health World

open access: yesFood Frontiers, EarlyView.
Organ‐on‐chips offer a promising tool for evaluating food and feed safety. Organ‐on‐chips also present a scientifically robust and ethical alternative to animal studies. ABSTRACT The One Health approach emphasizes the interconnectedness of human, animal, and environmental health, recognizing that the health of each is interdependent and influenced by ...

Yolk sac carbohydrate levels and gene expression of key gluconeogenic and glycogenic enzymes during chick embryonic development.

open access: yesPoultry Science, 2012
Glycogen and glucose concentrations (mg/g of tissue) and amounts (mg) were determined in the yolks of fertile eggs on the day of set and in the yolk sac (YS) and liver of broiler chick embryos between 11 and 21 embryonic days of age (E).

Molluscan Shells, Spicules, and Gladii Are Evolutionarily Deeply Conserved

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Evolutionarily conserved transcription factor encoding genes and other genes are expressed in the epithelia that give rise to spicules (green) and/or shells (blue) in developmental stages of diverse mollusks, including polyplacophorans, aplacophorans, scaphopods, and cephalopods.

Influence of In Ovo Leptin Injection into Yolk Sac on Embryo Development, Blood Biochemical Parameters and Lipid Metabolism of Broiler Chicks during Early Post-Hatching Period

open access: yesYüzüncü Yil Üniversitesi Tarim Bilimleri Dergisi, 2022
The study aimed to investigate the effect of in ovo (IO) leptin injection on yolk sac leptin concentration, embryo development, blood lipid metabolism, and biochemical parameters of broiler chicks during the early post-hatching period. Hatching eggs were

Etv2 Is Expressed in the Yolk Sac Hematopoietic and Endothelial Progenitors and Regulates Lmo2 Gene Expression

open access: yesStem Cells, 2012
During embryogenesis, the endothelial and the hematopoietic lineages first appear during gastrulation in the blood island of the yolk sac. We have previously reported that an Ets variant gene 2 (Etv2/ER71) mutant embryo lacks hematopoietic and ...

Design, Synthesis, and In Silico Insights of new 4‐Piperazinylquinolines as Antiproliferative Agents against NCI Renal Cancer Cell Lines

open access: yesChemistryOpen, EarlyView.
A novel series of hybrid 4‐(4‐benzoylpiperazin‐1‐yl)‐6‐nitroquinoline‐3‐carbonitrile derivatives has been designed, synthetized and evaluated for anticancer properties on the NCI60 panel. Strong antiproliferative effects have been detected against renal cancer cells.

Ontogeny of arterial macrophages defines their functions in homeostasis and inflammation

open access: yesNature Communications, 2020
Arterial macrophages develop from either yolk sac or bone marrow progenitors. Here, the author show that ageing-induced reduction of arterial macrophages is not replenished by bone marrow-derived cells, but under inflammatory conditions circulating ...
