Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

476
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Hormonal Regulation

33.4K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.7K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Plant Hormones01:56

Plant Hormones

24.3K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Cancer Prevention

6.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
Some...

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Area of Science:

  • Biochemistry
  • Pharmacology
  • Nutritional Science

Background:

  • Phytoestrogens are plant-derived compounds structurally and functionally analogous to mammalian estrogens.
  • They exhibit diverse health benefits, acting as both estrogen agonists and antagonists via nuclear estrogen receptor interaction.
  • Key classes include isoflavones, coumestans, and lignans.

Purpose of the Study:

  • To provide a comprehensive review of phytoestrogens.
  • To elucidate their mechanisms of action, botanical sources, and classification.
  • To discuss clinical implications, therapeutic effects, and safety concerns.

Main Methods:

  • Literature review of scientific studies on phytoestrogens.
  • Analysis of their interaction with estrogen receptor isoforms (ERα and ERβ).
  • Evaluation of clinical data regarding their efficacy and safety.

Main Results:

  • Phytoestrogens demonstrate potential benefits for menopausal symptoms, cardiovascular health, and bone health.
  • Their effects are concentration- and bioavailability-dependent.
  • The review covers identification techniques, side effects, and pharmacological actions.

Conclusions:

  • Phytoestrogens represent a promising area for therapeutic intervention, particularly as adjuncts to hormone therapy.
  • Further research is warranted to fully understand their long-term safety and efficacy.
  • Future directions include optimizing bioavailability and exploring novel therapeutic applications.
