Before 1917 the U.S. Virgin Islands were held by the Danish and called the Danish West Indies but the name was changed when the United States acquired them by purchase.Cellular Structures: Components of a cell.Microscopy: The use of instrumentation and techniques for visualizing material and details that cannot be seen by the unaided eye. It is usually done by enlarging images, transmitted by light or electron beams, with optical or magnetic lenses that magnify the entire image field. With scanning microscopy, images are generated by collecting output from the specimen in a point-by-point fashion, on a magnified scale, as it is scanned by a narrow beam of light or electrons, a laser, a conductive probe, or a topographical probe.Microscopy, Fluorescence: Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.Notophthalmus: A genus of newts of the Salamandridae family found in North America in areas east of the 100th meridian. A common species is NOTOPHTHALMUS VIRIDESCENS.Molecular Imaging: The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; FLUORESCENCE IMAGING; and MICROSCOPY.Life Expectancy: Based on known statistical data, the number of years which any person of a given age may reasonably expected to live.Search Engine: Software used to locate data or information stored in machine-readable form locally or at a distance such as an INTERNET site.Circadian Rhythm: The regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, and feeding.Information Storage and Retrieval: Organized activities related to the storage, location, search, and retrieval of information.PubMed: A bibliographic database that includes MEDLINE as its primary subset. It is produced by the National Center for Biotechnology Information (NCBI), part of the NATIONAL LIBRARY OF MEDICINE. PubMed, which is searchable through NLM's Web site, also includes access to additional citations to selected life sciences journals not in MEDLINE, and links to other resources such as the full-text of articles at participating publishers' Web sites, NCBI's molecular biology databases, and PubMed Central.Acetylserotonin O-Methyltransferase: An enzyme that catalyzes the transfer of a methyl group from S-adenosylmethionine to N-acetylserotonin to form N-acetyl-5-methoxytryptamine (MELATONIN).Internet: A loose confederation of computer communication networks around the world. The networks that make up the Internet are connected through several backbone networks. The Internet grew out of the US Government ARPAnet project and was designed to facilitate information exchange.Shame: An emotional attitude excited by realization of a shortcoming or impropriety.Viscum album: A plant species of the family VISCACEAE, order Santalales, subclass Rosidae. This is the traditional mistletoe of literature and Christmas. Members contain viscotoxin (5 kDa basic polypeptides related to thionins), beta-galactoside- and N-acetyl-D-galactosamine-specific lectin II (60 kDa), and polysaccharides. Mistletoe lectin I is a type 2 ribosome-inactivating protein. Commercial extracts include Plenosol, Eurixor, Helixor Isorel, Iscador, and NSC 635089 (ANTINEOPLASTIC AGENTS, PHYTOGENIC).Chenopodium album: A plant species in the CHENOPODIUM genus known for edible greens.Love: Affection; in psychiatry commonly refers to pleasure, particularly as it applies to gratifying experiences between individuals.Taste: The ability to detect chemicals through gustatory receptors in the mouth, including those on the TONGUE; the PALATE; the PHARYNX; and the EPIGLOTTIS.Ribosome Inactivating Proteins, Type 2: Ribosome inactivating proteins consisting of two polypeptide chains, the toxic A subunit and a lectin B subunit, linked by disulfide bridges. The lectin portion binds to cell surfaces and facilitates transport into the ENDOPLASMIC RETICULUM.Drama: A composition in prose or verse presenting in dialogue or pantomime a story involving various characters, usually intended to be acted on a stage and to be regarded as a form of entertainment. (From Random House Unabridged Dictionary, 2d ed)Sociometric Techniques: Methods for quantitatively assessing and measuring interpersonal and group relationships.Rubber: A high-molecular-weight polymeric elastomer derived from the milk juice (LATEX) of HEVEA brasiliensis and other trees and plants. It is a substance that can be stretched at room temperature to at least twice its original length and after releasing the stress, retract rapidly, and recover its original dimensions fully.Famous PersonsMedicine in Literature: Written or other literary works whose subject matter is medical or about the profession of medicine and related areas.Imitative Behavior: The mimicking of the behavior of one individual by another.Schistosomatidae: A family of blood flukes of the class Trematoda which is found in animals and man.
