3. Steroid hormones in fish reproduction

The changes in stress indices and some steroid hormones of Cyprinus carpio broodstocks in different stages of artificial reproduction

 Blood is directly involved in many metabolic processes, and blood and hormonal assessments can be helpful in diagnosing the physiological status of fish. In this study, changes in stress indices (glucose and cortisol) and steroid hormones (testosterone, estradiol and progesterone) of sea carp broodstocks in three stages, before hormone injection, after injection and after artificial reproducti...

Steroid Hormones: Membrane transporters of steroid hormones

The discovery of a plasma membrane ABC protein that exports steroids in yeast highlights the possibility that similar membrane sorting systems in mammalian cells may modulate the access of steroids to their receptors.

Hormones in Reproduction

Hormones in Reproduction

Nc ORMAL reproduction and lactation in domestic animals are regulated by hormones, a group of chemical materials that are secreted by the ductless or endocrine glands directly into the blood stream. The blood carries these chemical messengers to the parts of the body where they produce their effects. Of the endocrine glands, the pituitary is the most important. In the cow it is about the size o...

The Steroid Hormones in Pregnancy

THE marked changes in hormone production in pregnancy are associated with changes in metabolism and function. Much of the work which has been done and is being continued in the Clinical Research Unit of this department is concerned with the changes in body composition in normal and abnormal pregnancy and the puerperium and in the uterine activity in la;bour. The earlier endocrine work had been ...
