Hyalinization is a process of conversion of stromal connective tissue into a homogeneous, acellular translucent material. What causes hyalinization?
Renal arteriolar hyalinization was significantly associated with mortality from cerebrovascular disease but not from CHD. It is possible that a common antecedent factor such as hypertension50 or glucose intolerance might lead to both arteriolar hyalinization and atherosclerosis in multiple locations.
What is hyaline degeneration?
Medical Definition of hyaline degeneration : tissue degeneration chiefly of connective tissues in which structural elements of affected cells are replaced by homogeneous translucent material that stains intensely with acid stains. What sclerosis means?
Sclerosis: Localized hardening of skin. Sclerosis is generally caused by underlying diseases, such as diabetes and scleroderma.
What is Hyalinization of seminiferous tubules?
In complete tubular hyalinization there are no germ cells or Sertoli cells in the semini- ferous tubules of the testis. Light microscopically the seminiferous tubules are filled with homogenous eosinophilic material. What organs are prone to hyaline degeneration and amyloidosis?
Amyloidosis and hyaline degeneration are often observed in small muscular arteries of the myocardium, lungs, and spleen of old dogs. Lesions in the intramyocardial arteries can cause small foci of myocardial infarction.
Frequently Asked Questions(FAQ)
Is hyaline degeneration reversible?
Hyaline degeneration is irreversible condition.
What causes hyaline arteriosclerosis?
Hyaline arteriolosclerosis It is associated with aging, hypertension, diabetes mellitus and may be seen in response to certain drugs (calcineurin inhibitors). It is often seen in the context of kidney pathology.
What is hyaline casts in urine?
Hyaline casts are a type of urinary cast, which is a cluster of urinary particles, such as cells, fat bodies, or microorganisms, held together by a protein matrix and found in the urine.
What is hyaline anatomy?
Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. … It is also most commonly found in the ribs, nose, larynx, and trachea. Hyaline cartilage is pearl-grey in color, with a firm consistency and has a considerable amount of collagen.
What does hyaline mean in science?
What is hyaline in medicine?
The word hyaline comes from the Greek word hyalos meaning glass or transparent stone such as crystal. The membrane in hyaline membrane disease looks glassy. Hyaline membrane disease is now commonly called respiratory distress syndrome (RDS). It is caused by a deficiency of a molecule called surfactant.
What forms of degeneration are undergone by hyaline?
- degeneration of brain cells and of the macula retinae, as occurs in tay-sachs disease.
- any lipidosis with cerebral lesions and degeneration of the retinal macula.
- any form of neuronal ceroid-lipofuscinosis.
What is hyaline made of?
Hyaline cartilage, the most common type of cartilage, is composed of type II collagen and chondromucoprotein and often has a glassy appearance. Note the numerous chondrocytes in this image, each located within lacunae and surrounded by the cartilage they have produced.
What is the difference between scoliosis and sclerosis?
Scoliosis is a structural issue, while multiple sclerosis is an autoimmune disease of the central nervous system.
What are usually the first signs of MS?
Common early signs of multiple sclerosis (MS) include:
- vision problems.
- tingling and numbness.
- pains and spasms.
- weakness or fatigue.
- balance problems or dizziness.
- bladder issues.
- sexual dysfunction.
- cognitive problems.
What age can you get multiple sclerosis?
It’s most commonly diagnosed in people in their 20s and 30s, although it can develop at any age. It’s about 2 to 3 times more common in women than men. MS is 1 of the most common causes of disability in younger adults.
What is rated testis?
A network of small tubes in the testicle that helps move sperm cells (male reproductive cells) from the testicle to the epididymis. The epididymis is where the sperm mature and are stored.
What is produced in seminiferous tubules?
coiled tubules known as the seminiferous tubules; the sperm cells are produced within the walls of the tubules. Within the walls of the tubules, also, are many randomly scattered cells, called Sertoli cells, that function to support and nourish the immature sperm cells by giving them nutrients and blood products.…
What is other name of Leydig cell?
Leydig cells, also known as interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle.
What is leiomyoma with Hyalinization?
Hyalinization occurs in more than 60% of leiomyomas and is usually extensive (,1,,5,,6). At the microscopic level, hyalinization begins in the stromal component that separates the smooth muscle cells and then progresses to extensive replacement of the smooth muscle cells (,2).
Is degeneration reversible?
Degeneration is reversible but may progress to necrosis if injury persists. When it is associated with abnormal cell function, cell degeneration may also cause clinical disease.
What is the hyaline cartilage?
Hyaline cartilage, the most widely distributed form, has a pearl-gray semitranslucent matrix containing randomly oriented collagen fibrils but relatively little elastin. It is normally found on surfaces of joints and in the cartilage making up the fetal skeleton.
What is the difference between apoptosis and necrosis?
Apoptosis is described as an active, programmed process of autonomous cellular dismantling that avoids eliciting inflammation. Necrosis has been characterized as passive, accidental cell death resulting from environmental perturbations with uncontrolled release of inflammatory cellular contents.
Is apoptosis reversible or irreversible?
It is currently believed that apoptosis induction may be an irreversible process. Initial results from our laboratory have shown that DNA repair is activated early in p53-induced apoptosis, and that early stages may indeed be reversible.
What are signs of irreversible cell injury?
- distortion of microvilli.
- loosening of intercellular attachments.
- mitochondrial changes.
- dilation of the endoplasmic reticulum.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
