We determined the transcript content of three genes involved in the metabolism of glucocorticoids (GC) in bovine in vitro fertilized embryos (2-blastomere stage until hatched blastocyst), trophoblast as well as the oviduct (Day 2-4 of the estrous cycle) and endometrium (Day 16 of the cycle and pregnancy). Since mRNA expression of the glucocorticoid receptor and two enzymes responsible for GC pr...

BACKGROUND Egg-associated transmission to humans seems to be characteristic of the Salmonella serotype Enteritidis, explaining why this particular serotype has caused a worldwide pandemic since the mid '80s. Salmonella Enteritidis is much more capable to persistently colonize the laying hen reproductive tract and to survive in the hostile egg white, as compared to other serotypes. PRESENTATIO...

BACKGROUND Although chicken oviduct is a useful model and target tissue for reproductive biology and transgenesis, little is known because of the highly specific hormonal regulation and the lack of fundamental researches, including lectin-binding activities and glycobiology. Because lectin is attached to secreted glycoproteins, we hypothesized that lectin could be bound to secretory egg-white p...

Malformations which occur during the development of the avian body organs can lead to structural and functional abnormalities. Most defects are recognized at hatching, but some go undetected until somewhat later. The cause of the majority of animal congenital malformations is unknown. A significant proportion of congenital malformations of unknown cause are likely to have an important genetic c...

The purpose of the study is to features macro- and microscopic structure avian uterus in hen Haysex white cross. objects were 10 carcasses adult hens, cross-hysex white, aged 160-180 days. To oviduct, method conventional fine dissection was used. For histological examination, material fixed a 10% aqueous solution neutral formalin, followed by pouring into paraffin. As result our research, we no...

We have examined the question, is the carbohydrate moiety of ovalbumin attached to nascent chains or to the completed protein after its release from polyribosomes. Ovalbumin nascent chains have been isolated from hen oviduct by immunoprecipitation of ovalbumin-synthesizing polysomes and subsequent isolation of peptidyl-tRNA by DEAE-cellulose chromatography. Our results indicate that both glucos...
