Isolation of Bacterial pathogens from dead- in- shell Chicken embryos from local Hatcheries
… been experiencing losses due to dead-in-shell embryos for quite sometime. Numerous Salmonella serotypes have been frequently recorded in poultry population in Zambia, but no information is available on bacterial association with dead-in-shell mortality in hatcheries. Hence investigation into …

Heart rate and oxygen consumption during the critical prenatal period in chicken embryos (Gallus gallus): Influence of light cues and the onset of pulmonary ventilation.
… heart rate or oxygen consumption in late stage embryos (days 17-19.5) with light as a zeitgeber, chicken embryos were incubated in complete darkness (D:D) and 12:12 light:dark cycle (L:D). Light had no impact on oxygen consumption (390 µL O2∙min-1∙egg-1) but increased heart rate for …

Hematocrit, hematocrit Regulation and its effect on oxygen consumption in the late stage chicken embryo (Gallus domesticus).
… have the potential to affect developing embryos. To examine the ability of chicken embryos at day 15 to regulate hematocrit, they were subjected to either repeated saline injections (5% of total blood volume) or repeated blood removal (5% of total blood volume). Embryos showed an ability …

Discovery of Novel Mechanisms Regulating Cancer Extravasation in the Chorioallantoic Membrane Model
… events. I used the chorioallantoic membrane of chicken embryos as a model system of extravasation as it provides an accessible and highly vascularized structure. The combination of the chorioallantoic membrane of chicken embryos, nanoscale flow cytometry, and confocal microscopy-based intravital …

Induction of the retinal pigment epithelium of the chicken embryonic eye
… 1) when induction of the RPE has occurred in chicken embryos and 2) to investigate whether contact with the presumptive neural retina (NR) is required for RPE differentiation. In order to investigate when RPE induction has occurred, early expression of two genes involved in pigmentation were …

Spontaneous directional preferences in taxonomically and ecologically distinct organisms: examining cues and underlying mechanisms
… a possible magnetic alignment response in chicken embryos. Although chicken embryos did show non-random alignment, we were not able to find a magnetic effect. Alignment is also an important feature of animal constructions and is very likely to have fitness consequences, which we explored in …

ESTABLISHING IN VITRO INTESTINAL EPITHELIAL CELL MODELS IN TRANSLATIONAL ANIMAL NUTRITION
… intestinal epithelial cell (IEC) culture from chicken embryos for the assessment of CPn against LPS stress, underpinning poultry nutrition. Utilizing different cell-based assays, we have successfully demonstrated the proliferative effects of n-3 PUFAs as eicosapentaenoic acid (EPA) and …

PCB Effects on Brain Type II 5'Deiodinase Activity in Developing Brids
… supply during development in (1) domestic chicken embryos (Gallus domesticus) exposed to a specific dioxin-like PCB congener (PCB-126) and (2) herring gull (Larus argentatus) embryos and pre-fledglings from Great Lakes sites with different chemical pollutant exposures. Specifically, PCB …

Development of Cardiovascular Regulation in Embryos of the Domestic Fowl (Gallus Gallus), with a Partial Comparison to Embryos of the Desert Tortoise (Gopherus Agassizii)
… basic cardiovascular regulation in the chicken embryo to provided the needed information for it's use an alternative to the fetal lamb. Developing chicken embryos rely on both alpha and beta adrenergic tones to maintain normal heart rate and arterial blood pressure during incubation. …

First-order statistical speckle models improve robustness and reproducibility of contrast-enhanced ultrasound perfusion estimates
… (RCC) in the chorioallantoic membrane (CAM) of chicken embryos. The ultimate goal of the PDX model is to screen RCC patients for de novo sunitinib resistance. The analysis of the first-order speckle statistics of contrast-enhanced ultrasound cine loops provides more robust and reproducible …

Functional profiles of growth-related genes during embryogenesis and postnatal development of chicken and mouse skeletal muscle
… follistatin, activin-B gene expressions during chicken embryonic development. Strong myostatin expression was found in the early chicken embryos (E 0, E 1) and the developmental expression pattern of myostatin mRNA coincided with the periods of primary and secondary muscle fiber formation. …

Effects of Homocysteine on Cardiac Neural Crest Cell Formation
… /?? Uw. Hcys was experimentally elevated in chicken embryos, 16 or 4 hrs before the stage when NC cells in the cardiac region of the neural tube began forming and migrating away from the neural tube. To evaluate the effect of Hcys on cell proliferation, 5-bromo-2'-deoxyuridine (BrdU) was used …

Synthesis and application of biomaterials containing the 1,3,5-triazaadamantane moiety or functionalized alginate
… as several months. Gels discs were implanted in chicken embryos and shown to be nontoxic and were shown to release protein in a controlled fashion. Finally, TAA cross-linkers were also reacted with low molecular weight polyethyleneimine (PEI) to synthesize degradable gene delivery vehicles. …

Targeted Oncolytic Virotherapy Using Newcastle Disease Virus Against Prostate Cancer
… Also, PSA-cleavable NDV failed to replicate in chicken embryos, indicating absence of pathogenicity to its natural host, chickens. Prostaspheres generated from DU-145 CaP cell line derived xenografts showed self-renewal, proliferative and clonogenic potential in vitro, and exhibited increased …

Wrinkling Patterns on Curved Surface with Gradient Curvature under Compression
… pattern formation during the development of chicken embryos. We show from large-scale finite element simulations that hexagonal wrinkling patterns form for stiff cores whereas stripe-wrinkling patterns develop for soft cores. Hexagons and stripes co-exist to form hybrid patterns for cores …

The avian maternal environment: Its influence on the physiological mechanisms contributing to progeny production efficiency in chicken meat birds
… programming has enormous potential in the chicken meat industry due to meat chickens now spend ~40% of their life in-ovo, the stressors encountered by breeder hens throughout production that can affect the in-ovo environment during egg formation, and the pedigree breeding structure of the …
