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) Any of the RNA- and protein-rich cytoplasmic organelles that are sites of protein synthesis.
2) Small cellular components composed of specialized ribosomal RNA and protein; site of protein synthesis.
3) A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

1) Any of various round or long cellular organelles of most eukaryotes that are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes -- called also chondriosome.
2) Parts of a cell where aerobic production (also called cell respiration) takes place.
3) Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP). Mitochondria contain their own small chromosomes. Generally, mitochondria, and therefore mitochondrial DNA, are inherited only from the mother.

1) Any particle of coalesced lipids in the cytoplasm of a cell. May include associated proteins.
2) Cell substance contained in lipid vacoule.
Industry:Health care
1) Any pathological condition where fibrous connective tissue invades any organ, usually as a consequence of inflammation or other injury.
2) Development of excess fibrous connective tissue in an organ.
3) The growth of fibrous tissue.
Industry:Health care
1) Any process that establishes and transmits the specification of sexual status of an individual organism.
2) The mechanism in a given species by which sex is determined; in many species sex is determined at fertilization by the nature of the sperm that fertilizes the egg.

1) Any process which helps to produce biological responses to events in the environment or internal milieu; e.g., transduction of light into nerve impulses by the retina, or transduction of hormone binding into cellular events by hormone receptors.
2) The intercellular or intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the gamma-aminobutyric acid-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Industry:Health care
1) Any relative who is one meiosis away from a particular individual in a family (i.e., parent, sibling, offspring)
2) A first degree relative is a family member who shares about 50 percent of their genes with a particular individual in a family. First degree relatives include parents, offspring, and siblings.
Industry:Health care
1) Any visual display of structural or functional patterns of organs or tissues for diagnostic evaluation. It includes measuring physiologic and metabolic responses to physical and chemical stimuli, as well as ultramicroscopy.
2) Procedures that produce pictures of areas inside the body.
