1.

Antioxidant

A group of organic or inorganic substances capable of preventing the genotoxic and carcinogenic effects of free-radical compounds. Antioxidants bind to and neutralize ('scavenge') free radicals, thereby transforming them into non-toxic compounds and blocking their genotoxic and carcinogenic effects. This class of agents includes the vitamins C and E, the carotenoids, and selenium. Organic antioxidants are found in high concentrations in fruits, seeds and vegetables. (NCI04) [from NCI]

Corpus callosum agenesis

The corpus callosum is the largest fiber tract in the central nervous system and the major interhemispheric fiber bundle in the brain. Formation of the corpus callosum begins as early as 6 weeks' gestation, with the first fibers crossing the midline at 11 to 12 weeks' gestation, and completion of the basic shape by age 18 to 20 weeks (Schell-Apacik et al., 2008). Agenesis of the corpus callosum (ACC) is one of the most frequent malformations in brain with a reported incidence ranging between 0.5 and 70 in 10,000 births. ACC is a clinically and genetically heterogeneous condition, which can be observed either as an isolated condition or as a manifestation in the context of a congenital syndrome (see MOLECULAR GENETICS and Dobyns, 1996). Also see mirror movements-1 and/or agenesis of the corpus callosum (MRMV1; 157600). Schell-Apacik et al. (2008) noted that there is confusion in the literature regarding radiologic terminology concerning partial absence of the corpus callosum, where various designations have been used, including hypogenesis, hypoplasia, partial agenesis, or dysgenesis. [from GTR]

Fish-eye disease

Fish-eye disease, also called partial LCAT deficiency, is a disorder that causes the clear front surface of the eyes (the corneas) to gradually become cloudy. The cloudiness, which generally first appears in adolescence or early adulthood, consists of small grayish dots of cholesterol (opacities) distributed across the corneas. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals; it aids in many functions of the body but can become harmful in excessive amounts. As fish-eye disease progresses, the corneal cloudiness worsens and can lead to severely impaired vision. [from GTR]

Aplasia cutis congenita

Aplasia cutis congenita (ACC) is defined as congenital localized absence of skin. The skin appears as a thin, transparent membrane through which the underlying structures are visible. The location is usually on the scalp (Evers et al., 1995). Approximately 20 to 30% of cases have underlying osseous involvement (Elliott and Teebi, 1997). Autosomal dominant inheritance is most common, but recessive inheritance has also been reported. Cutaneous aplasia of the scalp vertex also occurs in Johanson-Blizzard syndrome (243800) and Adams-Oliver syndrome (AOS; 100300). A defect in the scalp is sometimes found in cases of trisomy 13 and in about 15% of cases of deletion of the short arm of chromosome 4, the Wolf-Hirschhorn syndrome (WHS; 194190) (Hirschhorn et al., 1965; Fryns et al., 1973). Evers et al. (1995) provided a list of disorders associated with aplasia cutis congenita, classified according to etiology. They also tabulated points of particular significance in history taking and examination of patients with ACC. [from GTR]

Fat

The glyceryl esters of a fatty acid, or of a mixture of fatty acids. They are generally odorless, colorless, and tasteless if pure, but they may be flavored according to origin. Fats are insoluble in water, soluble in most organic solvents. They occur in animal and vegetable tissue and are generally obtained by boiling or by extraction under pressure. They are important in the diet (DIETARY FATS) as a source of energy. (Grant & Hackh's Chemical Dictionary, 5th ed) [from MeSH]
