  Fabaceae



Fabaceae

   The large family of plants characterized by pods. Some are edible and some cause LATHYRISM; or FAVISM; and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various lectins like PHYTOHEMAGGLUTININ from PHASEOLUS. Many of them harbor nitrogen-fixing bacteria on their roots.

RELATED TERMS
--------------------------------------

Family
1. A group of individuals related by blood or marriage or by a feeling of closeness. 2. A biological classification of related plants or animals that is a division below the order and above the genus. 3. A group of genes related in structure and in function that descended from an ancestral gene. 4. A group of gene products similarly related in structure and function and of shared genetic descent. 5. Parents and their children. The most fundamental social group in humans.

FAVISM
A condition characterized by hemolytic anemia (breakup of red blood cells) after eating fava beans (Vicia fava) or being exposed to the pollen of the fava plant. This dangerous reaction occurs exclusively in people with a deficiency of the enzyme glucose-6-phosphate dehydrogenase (G6PD), an X-linked genetic trait. However, not all G6PD-deficient families appear at risk for favism, indicating the additional need for a single autosomal (not X-linked) gene to create the susceptibility to favism of G6PD-deficient persons. The active hemolytic principle in fava beans is > likely DOPA-quinone. Differences in susceptibility to favism may be related to differences in the enzymatic system that converts L-DOPA to DOPA-quinone.

Forms
A management function in which standards and guidelines are developed for the developing, maintaining, and handling of forms and records.

ACACIA
Any leguminous woody vine or tree of the genus Acacia, also called locust or wattle. The gums and tanning agents obtained from Acacia are called GUM ARABIC.

Bacteria
Single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life).



SIMILAR TERMS

PREVIOUS AND NEXT TERMS
--------------------------------------

Fx1A Renal Tubular Antigen
A complex of antigenic proteins obtained from the brush border of kidney tubules. It contains two principal components LDL-RECEPTOR RELATED PROTEIN 2 and LDL-RECEPTOR RELATED PROTEIN-ASSOCIATED PROTEIN. The name of this complex is derived from researcher, Dr. Walter Heymann, who developed an experimental model of membranous glomerulonephritis (GLOMERULONEPHRITIS) by injecting this antigenic complex into rats to induce an autoimmune response.

Fuzzy Logic
Approximate, quantitative reasoning that is concerned with the linguistic ambiguity which exists in natural or synthetic language. At its core are variables such as good, bad, and young as well as modifiers such as more, less, and very. These ordinary terms represent fuzzy sets in a particular problem. Fuzzy logic plays a key role in many medical expert systems.

Futility, Medical
The absence of a useful purpose or useful result in a diagnostic procedure or therapeutic intervention. The situation of a patient whose condition will not be improved by treatment or instances in which treatment preserves permanent unconsciousness or cannot end dependence on intensive medical care. (From Ann Intern Med 1990 Jun 15;112(12):949)

Fabricius Bursa
An epithelial outgrowth of the cloaca in birds similar to the thymus in mammals. It atrophies within 6 months after birth and remains as a fibrous remnant in adult birds. It is composed of lymphoid tissue and prior to involution, is the site of B-lymphocyte maturation.

Fabaviruses
A genus of the family COMOVIRIDAE with a wide host range among dicotyledons and some monocotyledons. They are transmitted nonpersistently by aphids. The type species is broad bean wilt virus 1.

Fabaceae

Fab Immunoglobulins
Antigen-binding fragments composed of one entire light chain and about half of one of the heavy chains, linked to each other by disulfide bonds. Fab contains the antigen binding site which is part of the variable region of the immunoglobulin molecule.

Face Peeling, Chemical
Application of a cauterant to the skin for the purpose of causing a superficial destruction of the epidermis and upper layers of the dermis. After healing, the treated area has new epithelium.

Face Lifts
Plastic surgery performed, usually by excision of skin, for the elimination of wrinkles from the skin.

Face Fly
A family of the order DIPTERA with over 700 species. Important species that may be mechanical vectors of disease include Musca domesticus (HOUSEFLIES), Musca autumnalis (face fly), Stomoxys calcitrans (stable fly), Haematobia irritans (horn fly) and Fannia spp.

Face
The anterior portion of the head that includes the skin, muscles, and structures of the forehead, eyes, nose, mouth, cheeks, and jaw.
