Selective changes in size and distribution of fibre types in vastus muscle from cases of different knee joint affections

Abstract

Different knee joint affections are apt to initiate different specific atrophy forms in quadriceps muscle. By a biopsy-technique using the histochemical demonstration of ATPase and succinate dehydrogenase fast twitch fibre atrophy can be correlated with increasing age and a moderate impairment but still ambulatory condition. Fast twitch and slow twitch fibres together show atrophy in those cases which are severely impaired and nearly immobilized. An isolated atrophy of slow twitch fibres was found in three patients suffering from frequent sudden short-lasting pain in the knee joint, although this condition may not be alone the cause for slow twitch fibre atrophy. The mechanisms leading to a selective atrophy of muscle fibre types are not fully understood. Nevertheless, a more clear understanding of the nature of skeletal muscle atrophy brought about by joint affections should be of benefit for a better concept of physiotherapeutical approaches: In fast twitch fibre atrophy maximal short lasting contractions followed by rather long periods of recovery should be performed (30). Slow twitch fibre atrophy should be influenced beneficially by chronic submaximal activity (46), whereas both fibre type atrophy should be treated by a co...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
