Effect of Melatonin on the Luteinizing Hormone Release Induced by Clomiphene and Luteinizing Hormone-Releasing Hormone

Experimental Biology and Medicine, 1976
The effect of melatonin on the LH-release response after the administration of synthetic LH-RH and clomiphene citrate was investigated in adult male rats. The sc administration of melatonin (1 mg/day) for 6 days produced a significant decrease in serum LH levels and in seminal vesicles and ventral prostate weights.

A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Micro‐and nanoplastics (MNPs) are breakdown products of plastics, and humans are exposed to these particles through air, water, food, and soil. There is a growing concern that human exposure to MNPs negatively impacts health. In this review we will discuss the potential health impact of MNPs on ovarian function and the hypothalamic–pituitary ...

Regulation of gene expression in ovarian cancer cells by luteinizing hormone receptor expression and activation

BMC Cancer, 2011
Background Since a substantial percentage of ovarian cancers express gonadotropin receptors and are responsive to the relatively high concentrations of pituitary gonadotropins during the postmenopausal years, it has been suggested that receptor ...

On the function of arginine in luteinizing hormone‐releasing hormone [PDF]

FEBS Letters, 1977
Many analogs of luteinizing hormone-releasing hormone (LH-RH) have been recently synthesized in order to investigate the significance of the various constituent amino acids in hormonal activity [ 1 ] . Assessments of the capacity of analogs to stimulate release of LH and FSH have revealed that arginine in position 8 on the peptide chain is critical for

Bifenthrin Under Scrutiny: Revisiting Toxicological Evidence Amid Regulatory Gaps

Journal of Applied Toxicology, EarlyView.
ABSTRACT Despite growing health concerns, bifenthrin (BF) remains widely used for controlling agricultural and residential pests. However, different perspectives on its toxicological profile and regulatory framework warrant a revisit and update on BF regulation towards a robust risk‐safety assessment.

Effects of growth hormone administration on luteinizing hormone secretion in healthy older men and women

Physiological Reports, 2017
The known interactions between the somatotropic and hypothalamic‐pituitary‐gonadal (HPG) axes have not been well delineated in older individuals. Aging‐associated decline in insulin like growth factor‐1 (IGF‐1) levels has been proposed to play a role in ...

P4‐ATPases as Phospholipid Flippases: From Membrane Dynamics to Human Disorders

Medicine Bulletin, EarlyView.
ABSTRACT P4‐ATPases (P4 subfamily of P‐type ATPases) flippase complex includes an α‐subunit responsible for catalysis and a supporting β‐subunit, which consumes energy by catalyzing the hydrolysis of ATP, thereby facilitating the translocation of aminophospholipids from the outer to the inner leaflet of cellular membranes to maintain the asymmetric ...
