Steroid hormone sulphation in lead workers.

Do dietary phytoestrogens influence susceptibility to hormone-dependent cancer by disrupting the metabolism of endogenous oestrogens?

Phytoestrogens are natural constituents of our diets that have been suggested to protect against hormone-dependent breast cancer. Some of the diverse effects of these compounds may be attributed to ligand-dependent differences in their interaction with oestrogen receptor sub-classes. However, phytoestrogens can also inhibit enzymes that are involved in the generation and removal of endogenous s...

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...

Determining the best dose of Ovulin hormone injection in artificial reproduction of Cyprinus carpio by examining some blood factors and steroid hormones

This study was performed to evaluate the best dose of Ovulin hormone in artificial reproduction of female sea carp broodstocks in the spring of 2021 in the bone reproduction and breeding center of Sijual in Bandar-e-Turkmen, Golestan province. 12 adult female sea carp with an average weight of 1750.46 ± 312.58 g were injected at doses of 0.4, 0.5, 0.6 and 0.7 ml / kg body weight of Ovulin hormo...

Increased and mistimed sex hormone production in night shift workers.

BACKGROUND Night shift work has been associated with an increased risk for breast and prostate cancer. The effect of circadian disruption on sex steroid production is a possible underlying mechanism, underinvestigated in humans. We have assessed daily rhythms of sex hormones and melatonin in night and day shift workers of both sexes. METHODS We recruited 75 night and 42 day workers, ages 22 t...
