Endogenous antisense RNAs function as regulators of gene expression by a variety of mechanisms. Synthetic antisense RNAs are used to effect the functioning of specific genes for investigative or therapeutic purposes.Galectins: A class of animal lectins that bind specifically to beta-galactoside in a calcium-independent manner. Members of this class are distiguished from other lectins by the presence of a conserved carbohydrate recognition domain. The majority of proteins in this class bind to sugar molecules in a sulfhydryl-dependent manner and are often referred to as S-type lectins, however this property is not required for membership in this class.Bromochlorofluorocarbons: A series of hydrocarbons containing BROMINE; CHLORINE and FLOURINE.Fire Extinguishing Systems: Automatic or hand operated equipment used to control and extinguish fires.Chlorofluorocarbons, Methane: A group of methane-based halogenated hydrocarbons containing one or more fluorine and chlorine atoms.Natural Science Disciplines: The sciences dealing with processes observable in nature.First Aid: Emergency care or treatment given to a person who suddenly becomes ill or injured before full medical services become available.Lymphangioma, Cystic: A cystic growth originating from lymphatic tissue.
