AUTO - AIR BAGS |
|
An airbag, also known as a Supplementary/Secondary Restraint System (SRS) or as an Air Cushion Restraint System (ACRS), is a flexible membrane or envelope, inflatable to contain air or some other gas. Air bags are most commonly used for cushioning, in particular after very rapid inflation in the case of an automobile collision.

BICYCLE HELMETS |
|
A bicycle helmet is designed to provide head protection for cyclists. Helmets are most suitable for preventing injury in straight falls, and for reducing friction related damage to the head. Modern bicycle helmets were first developed in the 1970s.

CANCER - GENERAL |
|
Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. This unregulated growth is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, or are passed down generations as a result of germ line mutations.

CIVIL RIGHTS - EQUAL RIGHTS |
|
Civil rights are the protections and privileges of personal liberty given to all citizens by law. Civil rights are distinguished from "human rights" or "natural rights"; civil rights are rights that are bestowed by nations on those within their territorial boundaries, while natural or human rights are rights that many scholars claim ought to belong to all people. For example, the philosopher John Locke (1632-1704) argued that the natural rights of life, liberty, and property should be converted into civil rights and protected by the sovereign state as an aspect of the social contract. Others have argued that people acquire rights as an inalienable gift from a god or at a time of nature before governments were formed.

DEATH PENALTY |
|
Capital punishment, or the death penalty, is governmental killing by execution as punishment for a crime often called a capital offense or a capital crime. Historically, the execution of criminals and political opponents was used by nearly all societies either by means of judicial process or through political motivations such as the supression of political dissent. Among democratic countries around the world, most European and Latin American ones have abolished capital punishment (except the United States, Guatemala and most of the Caribbean), while democracies in Asia and Africa retain it. Among nondemocratic countries the use of the death penalty is common.

LASIK |
|
LASIK, an acronym for Laser-assisted In Situ Keratomileusis, is a form of refractive laser eye surgery procedure performed by ophthalmologists intended for correcting vision. The procedure is usually a preferred alternative to photorefractive keratectomy, PRK, as it requires less time for full recovery, and the patient experiences less pain overall.

SLEEP DISORDERS |
|
A sleep disorder (somnipathy) is a disorder in the sleep patterns of a person or animal. Some sleep disorders can interfere with mental and emotional function
|
STROKE |
|
A stroke, also known as cerebrovascular accident (CVA), is an acute neurologic injury whereby the blood supply to a part of the brain is interrupted, either by a clot in the artery or if the artery bursts. The result is that the part of the brain perfused by that artery no longer can receive oxygen carried by the blood and it dies (becomes necrotic) with cessation of function from that part of the brain. In addition to tissue death, hemorrhages also cause damage from physical impingement of blood on the brain tissue. Stroke is a medical emergency and can cause permanent neurologic damage or even death if not promptly diagnosed and treated. It is the third leading cause of death and adult disability in the US and industrialized European nations (Jauch, 2005).
