Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

open access: yesFood Frontiers, EarlyView.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Identification of differential gene expression in in vitro FSH treated pig granulosa cells using suppression subtractive hybridization

open access: yesReproductive Biology and Endocrinology, 2006
FSH, which binds to specific receptors on granulosa cells in mammals, plays a key role in folliculogenesis. Its biological activity involves stimulation of intercellular communication and upregulation of steroidogenesis, but the entire spectrum of the ...

Pulsatile Hormonal Signaling to Extracellular Signal-Regulated Kinase: Exploring System Sensitivity to Gonadotropin-Releasing Hormone Pulse Frequency and Width [PDF]

open access: yes, 2014
Gonadotropin-releasing hormone (GnRH) is secreted in brief pulses that stimulate synthesis and secretion of pituitary gonadotropin hormones and thereby mediate control of reproduction.

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

open access: yesInternational 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 ...

Expression of the gonadotropin receptors during follicular development

open access: yesReproductive Medicine and Biology, 2018
Background Gonadotropins induce follicular development that leads to ovulation and luteinization. In women, the level of gonadotropins, along with the expression of their receptors, changes dynamically throughout the menstrual cycle.

Regulatory Actions of LH and Follicle-Stimulating Hormone on Breast Cancer Cells and Mammary Tumors in Rats

open access: yesFrontiers in Endocrinology, 2018
Gonadotrophins are mainly known to influence the body through the formation of gonadal steroids. However, receptors for luteinizing hormone (LH) and follicular-stimulating hormone (FSH) are present in a set of extra-gonadal tissues in humans and animals,

Molecular Investigations on Angiogenesis and Oxidative Stress in Roe Deer (Capreolus capreolus) Bucks' Testes Throughout the Reproductive Cycle

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...

Gonadotropin Levels in Ovarian Cyst Fluids: A Predictor of Malignancy?

open access: yesThe International Journal of Biological Markers, 1998
Gonadotropins can stimulate ovarian cancer growth in cell cultures. Corresponding LH/hCG receptors have been demonstrated in ovarian cancer. However, reduction of elevated serum gonadotropins by GnRH analogs in ovarian cancer patients did not lead to ...

The unsolved case of “bone-impairing analgesics”. The endocrine effects of opioids on bone metabolism [PDF]

open access: yes, 2015
The current literature describes the possible risks for bone fracture in chronic analgesics users. There are three main hypotheses that could explain the increased risk of fracture associated with central analgesics, such as opioids: 1) the increased ...
