Morphology-Based In-Ovo Sexing of Chick Embryos Utilizing a Low-Cost Imaging Apparatus and Machine Learning

Animals
The routine culling of male chicks in the laying hen industry raises significant ethical, animal welfare, and sustainability concerns. Current methods to determine chick embryo sex before hatching are costly, time-consuming, and invasive.

Biallelic Truncating Variant in LRGUK Is Associated With Severe Multiple Morphological Abnormalities of the Sperm Flagella and Sperm Nuclear Defects in Humans

Clinical Genetics, EarlyView.
A homozygous truncating variant in LRGUK results in loss of the LRGUK protein and causes multiple morphological abnormalities of the flagella (MMAF), disrupted axonemal architecture, central pair defects, abnormal chromatin organization, and severe male infertility, establishing LRGUK as a novel human infertility gene.

Life‐stage variation in Sable Shearwater (Ardenna carneipes) physiology assessed using proteomics

Ibis, EarlyView.
Life‐stage transitions in seabirds involve substantial shifts in physiological demands, yet the molecular mechanisms underpinning these changes remain poorly resolved. Here we applied untargeted data‐independent acquisition mass spectrometry (DIA‐MS) to characterize and compare the plasma proteomes of fledgling and adult Sable Shearwaters Ardenna ...

Post vaccination myelitis in a young woman following administration of rabies chick embryo cell vaccine – a case report

IMC Journal of Medical Science, 2012
A case of post-vaccination myelitis following administration of chick embryo cell rabies vaccine in a 20 year-old young lady is described. The case presented with paraplegia five days after receiving the third dose (on 12th day) of the vaccine for rabies.

Timing pattern of Common Cuckoo parasitism and its relation to host nest attendance

Ibis, EarlyView.
Classical works show the adaptive importance of precise timing of egg‐laying in brood parasitic Common Cuckoos Cuculus canorus to ensure sufficient incubation time and successful hatching. Laying in the late afternoon has been suggested to increase the chance of secretive parasitism and therefore escape the aggressive mobbing by hosts, yet this ...

3D transparent technology displays the developmental patterns of ductus arteriosus morphology in chicken embryos before and after birth

Journal of Anatomy, EarlyView.
At the eighth week of human embryonic development, 3D transparent imaging enables clear visualization of the outflow tract's morphological features, revealing its anatomical components in detail. Abstract The ductus arteriosus (DA) is a critical fetal vascular structure that shunts blood from the pulmonary artery to the aorta, bypassing the non ...

Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

Journal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Neuroanatomy education through the years: Revisiting the teaching slides used by Sir Wilfrid Edward Le Gros Clark

Journal of Anatomy, EarlyView.
This paper examines the life and legacy of British anatomist Sir Wilfrid Le Gros Clark through his neuroanatomical teaching collection at the University of Oxford. The authors catalogued 103 specimens and analyzed selected slides—including cases of multiple sclerosis, amyotrophic lateral sclerosis, tabes dorsalis, syringomyelia, and the pineal gland's ...

The Biological Effects of Novel Synthetic Retinoids [PDF]

, 2010
Naturally occurring Retinoids are known to play a role in many developmental processes in the early embryo as well as being a potent tool for in vitro differentiation of stem cells. The exogenous application of these naturally occurring retinoids as well

Combination of In Ovo Nutritional Components Improves Embryonic Development, Growth Performance, and Gut Health in Broiler Chickens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of intra‐amniotic administration of combined energy, amino acid, and vitamin sources on embryonic development, post‐hatch growth performance, and intestinal health in broiler chickens. On Day 18 of incubation, 460 fertile Ross 308 eggs were allocated to four groups: non‐injected negative control (NC), saline ...
