Urease Activity Protection With EDTA Against Nanoparticles (Fe2O3 and Fe3O4) Inactivation
In this study the effects of Fe2O3 and Fe3O4 magnetic nanoparticles and EDTA on urease activity was investigated. The effect of nano-Fe2O3 and nano-Fe3O4 on urease activity were investigated. Urease activity was studies by UV-Vis spectrophotometry at 40 °C at pH = 7.2 using sodium phosphate as buffer. Measurements were carried out using 0.075 mg/ml of urease and a range of nano-Fe2O3 and nano-F...
متن کاملRole of gonadotrophic hormone in the initiation and progression of adrenal tumors in ovariectomized mice.
Ovariectomy of (C57 X NH) F1 mice resulted in estrogen-secreting adrenal adenomas and estrous-type vaginal smears. Parabiosis with intact (C57 X NH) F1 females usually converted the vaginal smears from estrous to diestrous but produced a constant-estrous type smear in the intact parabiont. Ovariectomy of the latter resulted usually in restoration of an estrous-type smear in the tumorous animal ...
متن کاملNeural transplantation in hypogonadal (hpg) mice - physiology and neurobiology.
The hypogonadal (hpg) mouse mutant has a deletion in the region encoding the hypothalamic gonadotrophic hormone-releasing hormone decapeptide. As a consequence pituitary gonadotrophic hormone synthesis and release is severely curtailed and there is little or no post-natal gonadal development. Grafts of late fetal/early neonatal brain tissue containing the decapeptide-producing neurones into the...
متن کاملGonadotrophic hormone secretion in the female ring dove in response to visual and auditory stimulation by the male.
Female ring doves secrete gonadotrophic hormone in response to courtship behaviour of the male. This investigation was concerned with the quantitative relationship between the courtship stimulation presented to females and the responses of their reproductive systems. In a first experiment the degree of female reproductive tract development was found to be correlated with the length of time of d...
متن کاملHypothalamic control of anterior pituitary function: a history.
The concept of neurohumoral control of anterior pituitary function championed by Geoffrey Harris was based upon clinical and biological observation backed by rigorous experimental testing. The areas of the brain involved in the control of gonadotrophic hormone synthesis and release were identified by electrical stimulation, lesioning and fibre tract cutting. The medial preoptic area (MPOA) prov...
