Autoimmune Disorders01:29

Autoimmune Disorders

657
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

5.0K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Myasthenia Gravis: Overview and Treatment

1.9K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

402
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

The Thyroid Gland01:23

The Thyroid Gland

4.2K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Inflammatory Bowel Disease IV: Pharmacological Management

176
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
Pharmacologic...

Summary
This summary is machine-generated.

Myoinositol (Myo) plays a key role in thyroid function and may help manage hypothyroidism. Supplementing Myoinositol plus Selenium (Myo+Se) reduced TSH levels and antithyroid antibodies in patients with subclinical hypothyroidism.

Area of Science:

  • Biochemistry
  • Endocrinology
  • Immunology

Background:

  • Myoinositol (Myo) is a cyclic polyol crucial for thyroid physiology.
  • Myo regulates iodine organification and thyroid hormone biosynthesis via hydrogen peroxide (H₂O₂) formation in thyrocytes.
  • Myo is involved in the thyroid stimulating hormone (TSH) signaling pathway, and its depletion is linked to thyroid diseases like hypothyroidism.

Purpose of the Study:

  • To review the role of Myoinositol in thyroidal physiology.
  • To explore the role of Myoinositol in managing thyroid diseases.
  • To summarize findings on Myo and Selenium (Myo+Se) treatment in subclinical hypothyroidism.

Main Methods:

  • Literature review summarizing existing research on Myoinositol's function in the thyroid.
  • Analysis of studies investigating the effects of Myo and Myo+Se supplementation on thyroid function markers.
  • Examination of Myo's role in TSH signaling and its impact on thyroid hormone biosynthesis.

Main Results:

  • Myoinositol is essential for thyroid function, regulating key processes like iodine organification.
  • Depletion of Myoinositol can contribute to the development of hypothyroidism.
  • Treatment with Myo+Se significantly decreased TSH levels and antithyroid autoantibodies in patients with subclinical hypothyroidism.

Conclusions:

  • Myoinositol is vital for maintaining thyroidal physiology and hormone synthesis.
  • Myoinositol plays a significant role in the management of certain thyroid conditions, including hypothyroidism.
  • Myo+Se supplementation shows promise in improving thyroid function markers in patients with subclinical hypothyroidism and autoimmune thyroiditis.
