Device Removal: Removal of an implanted therapeutic or prosthetic device.Hair Removal: Methods used to remove unwanted facial and body hair.Laser Therapy, Low-Level: Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as they are in LASER THERAPY.Hair: A filament-like structure consisting of a shaft which projects to the surface of the SKIN from a root which is softer than the shaft and lodges in the cavity of a HAIR FOLLICLE. It is found on most surfaces of the body.Lasers: An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.Hair Follicle: A tube-like invagination of the EPIDERMIS from which the hair shaft develops and into which SEBACEOUS GLANDS open.

Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.Cannibalism: Eating other individuals of one's own species.Bacteria: One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.Music: Sound that expresses emotion through rhythm, melody, and harmony.Corpse Dismemberment: Disjoining the limbs or other parts of a corpse, often in association with criminal acts.Singing: Modulation of human voice to produce sounds augmented by musical tonality and rhythm.Music Therapy: The use of music as an adjunctive therapy in the treatment of neurological, mental, or behavioral disorders.Pulmonary Embolism: Blocking of the PULMONARY ARTERY or one of its branches by an EMBOLUS.Airway Obstruction: Any hindrance to the passage of air into and out of the lungs.Intestinal Obstruction: Any impairment, arrest, or reversal of the normal flow of INTESTINAL CONTENTS toward the ANAL CANAL.Tears: The fluid secreted by the lacrimal glands. This fluid moistens the CONJUNCTIVA and CORNEA.Ultrasonic Surgical Procedures: The use of HIGH-ENERGY SHOCK WAVES, in the frequency range of 20-60 kHz, to cut through or remove tissue. The tissue fragmentation by ultrasonic surgical instruments is caused by mechanical effects not heat as with HIGH-INTENSITY FOCUSED ULTRASOUND ABLATION.Dermabrasion: The mechanical planing of the SKIN with sand paper, emery paper, or wire brushes, to promote reepithelialization and smoothing of skin disfigured by ACNE scars or dermal NEVI.Aortic Valve: The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.Vacuum: A space in which the pressure is far below atmospheric pressure so that the remaining gases do not affect processes being carried on in the space.Neurosurgery: A surgical specialty concerned with the treatment of diseases and disorders of the brain, spinal cord, and peripheral and sympathetic nervous system.Grooming: An animal's cleaning and caring for the body surface. This includes preening, the cleaning and oiling of feathers with the bill or of hair with the tongue.Respiratory Aspiration: Inhaling liquid or solids, such as stomach contents, into the RESPIRATORY TRACT. When this causes severe lung damage, it is called ASPIRATION PNEUMONIA.Dental High-Speed Equipment: Tools used in dentistry that operate at high rotation speeds.Hereditary Sensory and Autonomic Neuropathies: A group of inherited disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and clinically by loss of sensation and autonomic dysfunction. There are five subtypes. Type I features autosomal dominant inheritance and distal sensory involvement. Type II is characterized by autosomal inheritance and distal and proximal sensory loss. Type III is DYSAUTONOMIA, FAMILIAL. Type IV features insensitivity to pain, heat intolerance, and mental deficiency. Type V is characterized by a selective loss of pain with intact light touch and vibratory sensation. (From Joynt, Clinical Neurology, 1995, Ch51, pp142-4)Ceremonial Behavior: A series of actions, sometimes symbolic actions which may be associated with a behavior pattern, and are often indispensable to its performance.Commerce: The interchange of goods or commodities, especially on a large scale, between different countries or between populations within the same country. It includes trade (the buying, selling, or exchanging of commodities, whether wholesale or retail) and business (the purchase and sale of goods to make a profit). (From Random House Unabridged Dictionary, 2d ed, p411, p2005 & p283)Autonomic Pathways: Nerves and plexuses of the autonomic nervous system. The central nervous system structures which regulate the autonomic nervous system are not included.Sinoatrial Node: The small mass of modified cardiac muscle fibers located at the junction of the superior vena cava (VENA CAVA, SUPERIOR) and right atrium. Contraction impulses probably start in this node, spread over the atrium (HEART ATRIUM) and are then transmitted by the atrioventricular bundle (BUNDLE OF HIS) to the ventricle (HEART VENTRICLE).Physics: The study of those aspects of energy and matter in terms of elementary principles and laws. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Computer Simulation: Computer-based representation of physical systems and phenomena such as chemical processes.OhioNuclear Physics: The study of the characteristics, behavior, and internal structures of the atomic nucleus and its interactions with other nuclei. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Paclitaxel: A cyclodecane isolated from the bark of the Pacific yew tree, TAXUS BREVIFOLIA. It stabilizes MICROTUBULES in their polymerized form leading to cell death.Membrane Fusion: The adherence and merging of cell membranes, intracellular membranes, or artificial membranes to each other or to viruses, parasites, or interstitial particles through a variety of chemical and physical processes.Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task.Intrauterine Devices: Contraceptive devices placed high in the uterine fundus.Intrauterine Devices, Copper: Intrauterine contraceptive devices that depend on the release of metallic copper.Intrauterine Device Expulsion: Spontaneous loss of INTRAUTERINE DEVICES from the UTERUS.Intrauterine Device Migration: The shifting in position or location of an INTRAUTERINE DEVICE from its original placement.Uterine Perforation: A hole or break through the wall of the UTERUS, usually made by the placement of an instrument or INTRAUTERINE DEVICES.Intrauterine Devices, Medicated: Intrauterine devices that release contraceptive agents.Contraceptive Agents: Chemical substances that prevent or reduce the probability of CONCEPTION.Electrolysis: Destruction by passage of a galvanic electric current, as in disintegration of a chemical compound in solution.Hair Dyes: Dyes used as cosmetics to change hair color either permanently or temporarily.
