The normal function of Aβ is not certain, but plaques arise when the protein misfolds and begins to accumulate in the brain by a process of molecular templating ('seeding'). [36] Mathias Jucker and Lary Walker have likened this process to the formation and spread of prions in diseases known as spongiform encephalopathies or prion diseases.
Cerebral atherosclerosis is a type of atherosclerosis where build-up of plaque in the blood vessels of the brain occurs. Some of the main components of the plaques are connective tissue, extracellular matrix, including collagen, proteoglycans, fibronectin, and elastic fibers; crystalline cholesterol, cholesteryl esters, and phospholipids; cells such as monocyte derived macrophages, T ...
These can form a plaque that can lead to atherosclerosis and trigger myocardial infarction and stroke. [1] [2] [3] Foam cells are fat-laden cells with a M2 macrophage-like phenotype. They contain low density lipoproteins (LDL) and can be rapidly detected by examining a fatty plaque under a microscope after it is removed from the body. [4]
Plaque build-up often doesn’t cause symptoms, but it can block blood flow to vital organs like your heart. Coronary artery disease occurs when atherosclerosis affects the arteries supplying ...
The treatment is done to reduce pressure on the brain caused by any cerebrospinal fluid buildup and to reduce the number of cancer cells causing the pressure. For the best care, patients should see a physician who regularly treats leptomeningeal cancer and is most up-to-date on medicines that penetrate the blood-brain barrier, how to treat the ...
Radiation therapy uses high energy rays to destroy cancer cells or to shrink tumors. The kind of rays used are x-rays, gamma rays, electron beams or protons. According to the National Cancer Institute, [1] there are two types of radiation therapy: external radiation therapy; internal radiation therapy
