Chronic systemic inflammation is the result of release of pro-inflammatory cytokines from immune-related cells and the chronic activation of the innate immune system.It can contribute to the development or progression of certain conditions such as cardiovascular disease, cancer, diabetes mellitus, chronic kidney disease, non-alcoholic fatty liver disease, autoimmune and neurodegenerative ...
Almost any part of the eye can give important clues to the diagnosis of systemic diseases. Signs of a systemic disease may be evident on the outer surface of the eye (eyelids, conjunctiva and cornea), middle of the eye and at the back of the eye (retina)." [4] Since 500 B.C., some researchers have believed that the physical condition of the ...
Management of ALL is directed towards control of bone marrow and systemic (whole-body) disease. Additionally, treatment must prevent leukemic cells from spreading to other sites, particularly the central nervous system (CNS); periodic lumbar punctures are used for diagnostic purposes and to administer intrathecal prophylactic methotrexate.

Medications can be used to prevent cancer in a few circumstances. [145] In the general population, NSAIDs reduce the risk of colorectal cancer; however, due to cardiovascular and gastrointestinal side effects, they cause overall harm when used for prevention. [146] Aspirin has been found to reduce the risk of death from cancer by about 7%. [147]
Cancer is a group of diseases where cells multiply uncontrollably. [1] Normally, cells have a built-in process called apoptosis that triggers cell death to prevent excessive growth. However, when these processes are disrupted, cancer can develop. Studies show that cancer is one of the leading causes of death worldwide. [1]
The cells of the adaptive immune system are special types of leukocytes, called lymphocytes. B cells and T cells are the major types of lymphocytes and are derived from hematopoietic stem cells in the bone marrow. [57] B cells are involved in the humoral immune response, whereas T cells are involved in cell-mediated immune response.
To tightly control cell division, cells have processes within them that prevent cell growth and division. These processes are orchestrated by proteins encoded by tumor suppressor genes. These genes take information from the cell to ensure that it is ready to divide, and will halt division if not (when the DNA is damaged, for example). In cancer ...
The cell cycle.Many tumor suppressors work to regulate the cycle at specific checkpoints in order to prevent damaged cells from replicating. A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. [1]
