Serum Albumin Polymorphism in Quail and Chicken-quail Hybrids.
ERUM albumin polymorphism has been reported in such animals as pigs (KRISTJANSSON 1963), horses (STORMONT and SUZUKI 1963), cattle (ASHTON 1964; ASHTON and LAMPKIN 1965), chickens (MCINDOE 1962) and turkeys ( QUINTEROS, STEVENS, TORMONT and ASMUNDSON 1964). BECKMAN, CONTERIO and MAINARDI (1963) examined the serum protein patterns of avian species hybrids and found that in eight out of 11 inters...
متن کاملSteroidogenic activity of chicken ovary during pause in egg laying.
The present study was designed (i) to assess the changes in the activity of 3beta-hydroxysteroid dehydrogenase (3beta-HSD) and cytochrome P450 aromatase (P450arom) in the ovaries of hens which are subjected to a pause in egg laying by fasting, and (ii) relate these changes with progesterone (P(4)) and estradiol (E(2)) production in the ovary. Hy-Line Brown laying hens (n=90) were fasted for 5 d...
متن کاملComparative Analysis of Nkx2-5/GATA4/TBX5 Expression in Chicken, Quail and Chicken-quail Hybrids during the Early Stage of Cardiac Development in Embryos
The present study makes an investigation into expression of genes related to cardiac development in chicken, quail and chicken-quail hybrids during the early stage of embryogenesis. Real-time PCR was used to detect mRNA expressions of Nkx2-5, GATA4 and TBX5 in the heart of chicken, quail and chicken-quail hybrids embryos during the 3rd to 7th days of incubation. Results showed that NKX2-5 mRNA ...
متن کامل[Ciliogenesis in the mucous cells of the quail oviduct. I. Ultrastructural study in the laying quail]
The luminal epithelium of the oviduct (magnum) of laying quails is composed of ciliated cells and mucous cells. Ciliogenesis was observed in some of the mucous cells. Both centrioles of the diplosome migrate to the top of the cell, and one of them induces the formation of a rudimentary cilium. In some of the other cells, that are filled with mucous granules, the formation of basal bodies by an ...
متن کاملUterine junctional zone contractions during assisted reproduction cycles.
This study was designed to assess junctional zone contractions (JZ) during cycles of in-vitro fertilization (IVF) and embryo transfer in oocyte donors exposed to a long protocol regime for ovarian stimulation. Real-time transvaginal ultrasound and advanced audio-visual and computer technology were used to evaluate the contraction pattern, frequency and velocity. At the time of down-regulation J...
