Schumanniophyton Problematicum
''Schumanniophyton problematicum'' is a species of plant in the family Rubiaceae. It is found in Ivory Coast, Ghana, and Sierra Leone. It is threatened by habitat loss. Chemistry The plant has been found to contain the alkaloids rohitukine and rohitukine ''N''-oxide, and the iridoid glycosides scyphiphorin A1–A2 and scyphiphorin B1–B2. Alvocidib is a synthetic analog of rohitukine that acts as a CDK9 kinase inhibitor and is under clinical development for the treatment of acute myeloid leukemia. It has also been studied for the treatment of arthritis and atherosclerotic plaque formation Rohitukine was initially extracted from ''Aphanamixis polystachya'' (the alkaloid name being derived from the synonym ''Amoora rohituka'') and later from ''Dysoxylum binectariferum ''Dysoxylum gotadhora'' is a tree in the family Meliaceae. It is native to Bhutan, India, Laos, Nepal, Thailand, and Vietnam. The name ''Dysoxylum ficiforme'' (Wight) Gamble in India and Sri Lanka ...

Kinase Inhibitor
A protein kinase inhibitor is a type of enzyme inhibitor that blocks the action of one or more protein kinases. Protein kinases are enzymes that phosphorylate (add a phosphate, or PO4, group) to a protein and can modulate its function. The phosphate groups are usually added to serine, threonine, or tyrosine amino acids on the protein: most kinases act on both serine and threonine, the tyrosine kinases act on tyrosine, and a number (dual-specificity kinases) act on all three. There are also protein kinases that phosphorylate other amino acids, including histidine kinases that phosphorylate histidine residues. Phosphorylation regulates many biological processes, and protein kinase inhibitors can be used to treat diseases due to hyperactive protein kinases (including mutant or overexpressed kinases in cancer) or to modulate cell functions to overcome other disease drivers. Clinical use Kinase inhibitors such as dasatinib are often used in the treatment of cancer and inflammation. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meliaceae
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes, or clusters. Most species are evergreen, but some are deciduous, either in the dry season or in winter. The family includes about 53 genera and about 600 known species, with a pantropical distribution; one genus ('' Toona'') extends north into temperate China and south into southeast Australia, another (''Synoum'') into southeast Australia, and another (''Melia'') nearly as far north. They most commonly grow as understory trees in rainforests, but are also found in mangroves and arid regions. The fossil record of the family extends back into the Late Cretaceous. Uses Various species are used for vegetable oil, soap-making, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dysoxylum
''Dysoxylum'' is a flowering plant genus of trees and shrubs from the mahogany family, Meliaceae. Botanical science has recorded about eighty species in this genus, growing widely across the regions of Malesia, the western Pacific ocean, Australia and south & southeastern Asia; centred on the tropics between the Pacific and Indian Oceans. They grow naturally in New Guinea, eastern and northern Australia, New Caledonia, Fiji, SE Asia, southern China, the Indian subcontinent, the Philippines, Taiwan, and in the western Pacific Ocean their most easterly occurrences, in the Caroline Islands, New Zealand and Niue. The etymology of its name ''Dysoxylum'' derives from the Greek word ‘''Dys''’ meaning "bad" referring to "ill-smelling" and ‘''Xylon''’ meaning "wood". Distribution New Guinea has records of twenty eight species growing naturally, sixteen of them endemic. New Caledonia has recorded nine, eight of them endemic. Fiji has recorded nine, seven of them endemic. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atherosclerotic Plaque
An atheroma, or atheromatous plaque, is an abnormal and reversible accumulation of material in the inner layer of an arterial wall. The material consists of mostly macrophage cells, or debris, containing lipids, calcium and a variable amount of fibrous connective tissue. The accumulated material forms a swelling in the artery wall, which may intrude into the lumen of the artery, narrowing it and restricting blood flow. Atheroma is the pathological basis for the disease entity atherosclerosis, a subtype of arteriosclerosis. Signs and symptoms For most people, the first symptoms result from atheroma progression within the heart arteries, most commonly resulting in a heart attack and ensuing debility. The heart arteries are difficult to track because they are small (from about 5 mm down to microscopic), they are hidden deep within the chest and they never stop moving. Additionally, all mass-applied clinical strategies focus on both minimal cost and the overall safety of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthritis
Arthritis is a term often used to mean any disorder that affects joints. Symptoms generally include joint pain and stiffness. Other symptoms may include redness, warmth, swelling, and decreased range of motion of the affected joints. In some types of arthritis, other organs are also affected. Onset can be gradual or sudden. There are over 100 types of arthritis. The most common forms are osteoarthritis (degenerative joint disease) and rheumatoid arthritis. Osteoarthritis usually occurs with age and affects the fingers, knees, and hips. Rheumatoid arthritis is an autoimmune disorder that often affects the hands and feet. Other types include gout, lupus, fibromyalgia, and septic arthritis. They are all types of rheumatic disease. Treatment may include resting the joint and alternating between applying ice and heat. Weight loss and exercise may also be useful. Recommended medications may depend on the form of arthritis. These may include pain medications such as ibuprofen ...

Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with haematopoiesis, normal blood cell production. Symptoms may include Fatigue, feeling tired, shortness of breath, Bruise, easy bruising and bleeding, and increased risk of infection. Occasionally, spread may occur to the brain, skin, or gums. As an acute leukemia, AML progresses rapidly, and is typically fatal within weeks or months if left untreated. Risk factors include smoking, previous chemotherapy or radiation therapy, myelodysplastic syndrome, and exposure to the chemical benzene. The underlying mechanism involves replacement of normal bone marrow with leukemia cells, which results in a anemia, drop in red blood cells, thrombocytopenia, platelets, and normal leukopenia, white blood cells. Diagnosis is generally based on bone marrow aspiration and specific blood tests. AML has several s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
