Hormonal Regulation01:40

Hormonal Regulation

47.7K
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Hormonal Regulation01:33

Hormonal Regulation

35.7K
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.

Menopause01:28

Menopause

3.5K
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

5.1K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

3.7K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

6.1K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral...

Summary
This summary is machine-generated.

Long term hormone replacement therapy (HRT) may offer benefits against cardiovascular disease and osteoporosis, but risks like thrombosis and breast cancer require careful consideration. Evidence remains controversial, necessitating a balance of potential advantages against known risks.

Area of Science:

  • Reproductive Medicine
  • Gerontology
  • Cardiovascular Medicine

Background:

  • Short-term hormone replacement therapy (HRT) is standard for menopausal symptom relief.
  • Increasing HRT use in Australia highlights the need to examine long-term benefits and risks.
  • Controversy surrounds the long-term efficacy and safety of HRT.

Purpose of the Study:

  • To evaluate HRT for preventing cardiovascular disease (CVD) and osteoporosis.
  • To assess the increased risks of thrombosis and potential breast cancer associated with HRT.
  • To review the existing evidence on long-term HRT use in postmenopausal women.

Main Methods:

  • Systematic review of epidemiological data.
  • Analysis of controlled clinical trials focusing on CVD prevention.
  • Examination of fracture endpoint data for osteoporosis treatment.

Main Results:

  • Epidemiological data suggests HRT may protect against CVD and fractures.
  • Limited controlled trials show no CVD prevention benefit from HRT.
  • Controlled data for HRT in osteoporosis treatment is scarce.
  • Epidemiological studies suggest a potential increase in breast cancer risk with HRT.

Conclusions:

  • HRT's potential long-term benefits for CVD and osteoporosis must be weighed against risks.
  • Increased thrombosis risk is associated with HRT use.
  • The potential for increased breast cancer risk warrants consideration.
  • Balancing benefits and risks is crucial for informed HRT decisions in postmenopausal women.
