Abnormalities of the fibrinogen molecule may impair any of the major steps involved in the conversion of fibrinogen into stabilized fibrin, such as cleavage of the fibrinopeptides by thrombin, polymerization and cross-linking of fibrin. The resulting dysfibrinogenemias can be clinically silent or can be associated with bleeding, thrombosis or defective wound healing.Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.Small Business: For-profit enterprise with relatively few to moderate number of employees and low to moderate volume of sales.Dancing: Rhythmic and patterned body movements which are usually performed to music.Residence Characteristics: Elements of residence that characterize a population.

The drugs may be legal or illegal, but their use often results in adverse medical, legal, or social consequences for the users.Catchment Area (Health): A geographic area defined and served by a health program or institution.Wine: Fermented juice of fresh grapes or of other fruit or plant products used as a beverage.Floors and Floorcoverings: The surface of a structure upon which one stands or walks.Designer Drugs: Drugs designed and synthesized, often for illegal street use, by modification of existing drug structures (e.g., amphetamines). Of special interest are MPTP (a reverse ester of meperidine), MDA (3,4-methylenedioxyamphetamine), and MDMA (3,4-methylenedioxymethamphetamine). Many drugs act on the aminergic system, the physiologically active biogenic amines.Occupational Injuries: Injuries sustained from incidents in the course of work-related activities.Butylene Glycols: 4-carbon straight chain aliphatic hydrocarbons substituted with two hydroxyl groups. The hydroxyl groups cannot be on the same carbon atom.Patient Protection and Affordable Care Act: An Act prohibiting a health plan from establishing lifetime limits or annual limits on the dollar value of benefits for any participant or beneficiary after January 1, 2014. It permits a restricted annual limit for plan years beginning prior to January 1, 2014. It provides that a health plan shall not be prevented from placing annual or lifetime per-beneficiary limits on covered benefits. The Act sets up a competitive health insurance market.Miller Fisher Syndrome: A variant of the GUILLAIN-BARRE SYNDROME characterized by the acute onset of oculomotor dysfunction, ataxia, and loss of deep tendon reflexes with relative sparing of strength in the extremities and trunk. The ataxia is produced by peripheral sensory nerve dysfunction and not by cerebellar injury. Facial weakness and sensory loss may also occur. The process is mediated by autoantibodies directed against a component of myelin found in peripheral nerves. (Adams et al., Principles of Neurology, 6th ed, p1313; Neurology 1987 Sep;37(9):1493-8)Facility Design and Construction: Architecture, exterior and interior design, and construction of facilities other than hospitals, e.g., dental schools, medical schools, ambulatory care clinics, and specified units of health care facilities. The concept also includes architecture, design, and construction of specialized contained, controlled, or closed research environments including those of space labs and stations.Septins: A family of GTP-binding proteins that were initially identified in YEASTS where they were shown to initiate the process of septation and bud formation. Septins form into hetero-oligomeric complexes that are comprised of several distinct septin subunits. These complexes can act as cytoskeletal elements that play important roles in CYTOKINESIS, cytoskeletal reorganization, BIOLOGICAL TRANSPORT, and membrane dynamics.Encyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)Housing, AnimalCrack Cocaine: The purified, alkaloidal, extra-potent form of cocaine. It is smoked (free-based), injected intravenously, and orally ingested. Use of crack results in alterations in function of the cardiovascular system, the autonomic nervous system, the central nervous system, and the gastrointestinal system. The slang term "crack" was derived from the crackling sound made upon igniting of this form of cocaine for smoking.Income: Revenues or receipts accruing from business enterprise, labor, or invested capital.Hospitals, Community: Institutions with permanent facilities and organized medical staff which provide the full range of hospital services primarily to a neighborhood area.Heart: The hollow, muscular organ that maintains the circulation of the blood.Gift Giving: The bestowing of tangible or intangible benefits, voluntarily and usually without expectation of anything in return.

(From Facts on File Dictionary of Health Care Management, 1988, p207)Blood Gas Monitoring, Transcutaneous: The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced hemoglobin.RestaurantsMenu PlanningBooksFamous PersonsVermontBreakfast: The first meal of the day.Fast Foods: Prepared food that is ready to eat or partially prepared food that has a final preparation time of a few minutes or less.Baseball: A competitive nine-member team sport including softball.Athletic Injuries: Injuries incurred during participation in competitive or non-competitive sports.Product Recalls and Withdrawals: The removal of a consumer product from the market place. The reason for the removal can be due a variety of causes, including the discovery of a manufacturing defect, a safety issue with the product's use, or marketing decisions.Sarraceniaceae: A plant family of the order Nepenthales.Athletes: Individuals who have developed skills, physical stamina and strength or participants in SPORTS or other physical activities.Salmonella: A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation.
