Mono-hydroxylated xanthophylls formed from the hydroxylation of BETA-CAROTENE. Isomers include: beta-cryptoxanthin, alpha-cryptoxanthin, and zeinoxanthin. The alpha- and beta-cryptoxanthin are provitamin A precursors.
A heterogeneous family of water-soluble structural proteins found in cells of the vertebrate lens. The presence of these proteins accounts for the transparency of the lens. The family is composed of four major groups, alpha, beta, gamma, and delta, and several minor groups, which are classed on the basis of size, charge, immunological properties, and vertebrate source. Alpha, beta, and delta crystallins occur in avian and reptilian lenses, while alpha, beta, and gamma crystallins occur in all other lenses.
The formation of crystalline substances from solutions or melts. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
The branch of science that deals with the geometric description of crystals and their internal arrangement. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
The study of crystal structure using X-RAY DIFFRACTION techniques. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

A genus of FLEAS in the family Pulicidae. It includes the cat flea (Ctenocephalides felis), one of the most common species on earth.
Phylum of marine colenterates characterized by eight comb rows of fused cilia on the body surface. In contrast to CNIDARIA they lack stinging cells, but they are voracious predators and possess sticky cells (colloblasts) for capturing prey. Most species are transparent and many exhibit bioluminescence.

An island in the Greater Antilles in the West Indies, south of Florida. With the adjacent islands it forms the Republic of Cuba. Its capital is Havana. It was discovered by Columbus on his first voyage in 1492 and conquered by Spain in 1511. It has a varied history under Spain, Great Britain, and the United States but has been independent since 1902. The name Cuba is said to be an Indian name of unknown origin but the language that gave the name is extinct, so the etymology is a conjecture. (From Webster's New Geographical Dictionary, 1988, p302 and Room, Brewer's Dictionary of Names, 1992, p132)
Compression of the ULNAR NERVE in the cubital tunnel, which is formed by the two heads of the flexor carpi ulnaris muscle, humeral-ulnar aponeurosis, and medial ligaments of the elbow. This condition may follow trauma or occur in association with processes which produce nerve enlargement or narrowing of the canal. Manifestations include elbow pain and PARESTHESIA radiating distally, weakness of ulnar innervated intrinsic hand muscles, and loss of sensation over the hypothenar region, fifth finger, and ulnar aspect of the ring finger.

A class of highly venomous jellyfish in the phylum CNIDARIA. They are referred to as box jellyfish based upon their cube (box) shape.
A genus of large SEA CUCUMBERS possessing the primitive radial configuration of podia in all five ambulacral areas.
A satellite RNA (not a satellite virus) which has several types. Different cucumoviruses can act as helper viruses for different types.
A plant genus of the family CUCURBITACEAE, order Violales, subclass Dilleniidae best known for cucumber (CUCUMIS SATIVUS) and cantaloupe (CUCUMIS MELO). Watermelon is a different genus, CITRULLUS. Bitter melon may refer to MOMORDICA or this genus.
A plant species of the family CUCURBITACEAE, order Violales, subclass Dilleniidae known for the melon fruits with reticulated (net) surface including cantaloupes, honeydew, casaba, and Persian melons.
A creeping annual plant species of the CUCURBITACEAE family. It has a rough succulent, trailing stem and hairy leaves with three to five pointed lobes.
A genus of plant viruses of the family BROMOVIRIDAE, which infect cucurbits and solanaceous plants. Transmission occurs via aphids in a non-persistent manner, and also via seeds. The type species Cucumber mosaic virus, a CUCUMOVIRUS, should not be confused with Cucumber green mottle mosaic virus, a TOBAMOVIRUS.
A plant genus of the family CUCURBITACEAE, order Violales, subclass Dilleniidae, which includes pumpkin, gourd and squash.
The gourd plant family of the order Violales, subclass Dilleniidae, class Magnoliopsida. It is sometimes placed in its own order, Cucurbitales. 'Melon' generally refers to CUCUMIS; CITRULLUS; or MOMORDICA.
Triterpenes that derive from LANOSTEROL by a shift of the C19 methyl to the C9 position. They are found in seeds and roots of CUCURBITACEAE and other plants and are noted for intense bitterness.
Signals for an action; that specific portion of a perceptual field or pattern of stimuli to which a subject has learned to respond.
a meiosis-specific regulatory factor of meiosis maturation

Endoscopic instruments used for viewing the rectovaginal pouch and pelvic viscera.
Endoscopic examination, therapy or surgery of the female pelvic viscera by means of an endoscope introduced into the pelvic cavity through the posterior vaginal fornix.
A genus of mosquitoes (CULICIDAE) commonly found in tropical regions. Species of this genus are vectors for ST. LOUIS ENCEPHALITIS as well as many other diseases of man and domestic and wild animals.
A family of the order DIPTERA that comprises the mosquitoes. The larval stages are aquatic, and the adults can be recognized by the characteristic WINGS, ANIMAL venation, the scales along the wing veins, and the long proboscis. Many species are of particular medical importance.
A family of structurally related proteins that were originally discovered for their role in cell-cycle regulation in CAENORHABDITIS ELEGANS. They play important roles in regulation of the CELL CYCLE and as components of UBIQUITIN-PROTEIN LIGASES.
Those aspects or characteristics which identify a culture.
Cultural and linguistic competence is a set of congruent behaviors, attitudes, and policies that come together in a system, agency, or among professionals that enables effective work in cross-cultural situations. Competence implies the capacity to function effectively as an individual and an organization within the context of the cultural beliefs, behaviors, and needs presented by consumers and their communities.
The absence of certain expected and acceptable cultural phenomena in the environment which results in the failure of the individual to communicate and respond in the most appropriate manner within the context of society. Language acquisition and language use are commonly used in assessing this concept.
Coexistence of numerous distinct ethnic, racial, religious, or cultural groups within one social unit, organization, or population. (From American Heritage Dictionary, 2d college ed., 1982, p955)
The continuous developmental process of a culture from simple to complex forms and from homogeneous to heterogeneous qualities. It is the change of cultures over time. Research in cultural evolution tries to understand the causal relationships that shape and change human culture in both the long and the short term.
Health care services that are respectful of and responsive to the health beliefs, practices and cultural and linguistic needs of diverse patients. The provider and the patient each bring their individual learned patterns of language and culture to the health care experience which must be transcended to achieve equal access and quality health care.
A collective expression for all behavior patterns acquired and socially transmitted through symbols. Culture includes customs, traditions, and language.
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
Culture media containing biologically active components obtained from previously cultured cells or tissues that have released into the media substances affecting certain cell functions (e.g., growth, lysis).
