Steroid hormones play a role in feminization of oviparous vertebrates. Vitellogenin (Vtg, egg yolk) induction has been used extensively as a biomarker of feminization. However, in some species of turtles there is evidence that high levels of estradiol are necessary to initially induce Vtg. Once ...
This chapter describes the mechanisms and models of peptide hormones, steroid hormones, and puffs in insect development. The postnatal physical development of homeothermic animals is chiefly a period of increase in size, with a few final touches such as the appearance of secondary sexual characterist...

These cellular processes are under the control of steroid and peptide hormones (Topper and Freeman 1980). Growth and limited differentiation occurs during puberty and requires the action of oestrogen, prolactin and members of the transforming growth factor (TGF)-尾 family. The epithelial cells form ...
Effect of weekly oral administration of Centchroman (3,4- trans-2,2-dimethyl-3-phenyl-4-(p-(β-pyrrolidinoethoxy)- phenyl)-7-methoxychroman) at 1 and 2.5 mg/kg for 12 Months on plasma estradiol, progesterone, luteinizing hormone and follicle stimulating hormone of female rhesus monkeys was...
It is important to note that leptin andghrelin receptorsoutside the ARC also contribute to the control of eating. These include leptin receptors in the VMH, NTS, VTA and in abdominal vagal afferents. The multiple points of entry of these hormones into the brain, similar to the multiplicity of...

Food intake and fat deposition are regulated by peptide neurotransmitters, most of them located in the brain, particularly in the hypothalamus (Elmquist et al. 1999; Kalra et al. 1999) and in the gut. This includes peptides that are (appetite stimulating
The results indicated that a carrageen an coating of liposomes increased the permeation rate of finasteride and progesterone (steroid hormones) over conventional liposomes (3.4 vs 2.9 µg/cm2/h and 0.74 vs 0.52 µg/cm2/h respectively). This has been attributed to the bio adhesive nature ...
12 Sex steroid hormones may play a relevant physiological role in the regulation of production and secretion of cardiac natriuretic peptides, and female steroid hormones, in particular estrogens, have a stimulating effect on the cardiac natriuretic hormone system.13 Prior studies in pregnancy have ...
