The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
1) A chronic, recurrent infection caused by the bacterium Mycobacterium tuberculosis. Tuberculosis (TB) may affect almost any tissue or organ of the body with the lungs being the most common site of infection. The clinical stages of TB are primary or initial infection, latent or dormant infection, and recrudescent or adult-type TB. Ninety to 95% of primary TB infections may go unrecognized. Histopathologically, tissue lesions consist of granulomas which usually undergo central caseation necrosis. Local symptoms of TB vary according to the part affected; acute symptoms include hectic fever, sweats, and emaciation; serious complications include granulomatous erosion of pulmonary bronchi associated with hemoptysis. If untreated, progressive TB may be associated with a high degree of mortality. This infection is frequently observed in immunocompromised individuals with AIDS or a history of illicit IV drug use.
2) A disease caused by a specific type of bacteria that spreads from one person to another through the air. Tuberculosis can affect many parts of the body, but most often affects the lungs. A person may not have symptoms of tuberculosis for years, but they may appear when the patient becomes ill with a serious condition like diabetes, AIDS, or cancer. Tuberculosis can usually be treated and cured with antibiotics. Also called TB.

1) A circumscribed melanosis consisting of a brown-pigmented, velvety verrucosity or fine papillomatosis appearing in the axillae and other body folds. It occurs in association with endocrine disorders, underlying malignancy, administration of certain drugs, or as in inherited disorder.
2) A skin disease characterized by gray-black warty patches usually situated in the axilla or groin or on elbows or knees and sometimes associated with cancer of abdominal viscera.

1) A class of enzymes that catalyze the formation of a bond between two substrate molecules, coupled with the hydrolysis of a pyrophosphate bond in ATP or a similar energy donor. (Dorland, 28th ed) EC 6.
2) Major class of enzymes that catalyse the linking together of two molecules (EC class 6) for example DNA ligases that link two fragments of DNA by forming a phosphodiester bond.
3) An enzyme that catalyzes the linking together of two molecules especially by using the energy derived from the concurrent splitting off of a pyrophosphate group from a triphosphate (as ATP).

1) A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from "star" cells) are irregularly shaped with many long processes, including those with "end feet" which form the glial (limiting) membrane and directly and indirectly contribute to the blood-brain barrier. They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with microglia) respond to injury.
2) A type of cell found in the brain and spinal cord. An astrocyte is a small, star-shaped glial cell (a cell that surrounds and supports nerve cells).

1) A class of lipoproteins responsible for transport of cholesterol to extrahepatic tissues. They are formed in the circulation when very-low-density lipoproteins are degraded first to intermediate-density lipoproteins and then to LDL by the gain and loss of specific apolipoproteins and the loss of most of their triglycerides. LDL are taken up and catabolized by both the liver and extrahepatic tissues by specific receptor-mediated endocytosis. (Dorland, 28th ed)
2) Low-density lipoprotein (LDL) is a lipoprotein that carries cholesterol around the body, for use by various cells. LDL transports cholesterol to the arteries and increased levels are associated with atherosclerosis, and thus myocardial infarctions and strokes. This is why cholesterol inside LDL lipoproteins is called bad cholesterol. (from Wikipedia)

1) A class of lipoproteins that transport triglycerides from the intestine and liver to adipose and muscle tissues. Synthesized by the liver, they contain primarily triglycerides in their lipid cores, with some cholesterol esters. As their triglycerides are cleaved by endothelial lipoprotein lipase and transferred to hepatic tissues, the VLDL (very-low-density lipoprotein) particles lose most of their apolipoprotein C and become intermediate-density lipoproteins. (Dorland, 28th ed)
