Early biochemical disorders in the hindlimb muscles following femoral artery stenosis in dogs: protein and electrolyte metabolism

Zeitschrift für experimentelle Chirurgie

Investigations regarding the metabolism of proteins and electrolytes in the hindlimb skeletal muscles were carried out in dogs with a moderate unilateral stenosis of femoral artery (reduction of almost 65% of its lumen) early after surgery. The results of these investigations were compared with those obtained by investigating the correspondent skeletal muscles of the opposite hindlimb. This comparison has revealed the following findings: (1) ischemia in a moderate form early elicites a remarkable K+ accumulation (not a K+ loss!) in the skeletal muscle without any change in the concentrations of other cations; (2) in this instance, an activation of muscle proteases and peptidases occurs meading to an important production of histamine, which is detectable in appreciable amounts in the ischemic muscle and, especially, in its effluent blood. On the basis of the findings reported in this study, as well as on the basis of our previous findings on the same experimental model, an approach to correlate and explain the early muscular metabolic disturbances induced by a moderate ischemia is discussed. In addition, it is to be pointed out that the presence of histamine in increased amounts in the effluent blood of a skeletal muscle mass co...Continue Reading

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.
