In humans, maternal thyroid hormones supply the fetus throughout pregnancy, and thyroid hormones play a critical role in fetal growth and neurodevelopment. OBJECTIVES We ...
Increased concern is being paid to the health and environmental risk caused by trace natural and synthetic hormones discharged from sewage treatment plant (STPs). This study, which is part of a larger project on investigation of hybrid membrane processes for trace hormones removal, focuses on binding of hormones to microfiltration hollow fibre membranes in filtration of solutions containing tra...

Artificially occurring parthenocarpy can be induced by exogenous application of plant hormones and is useful in the fruit production many crops trees. In cucumber (Cucumis sativus L.), a model species Cucurbitaceae family, auxin, gibberellin, cytokinin, brassinosteroids are known to induce parthenocarpy. tropical squash (Cucurbita moschata synthetic auxins parthenocarpy, but effects still unkno...
