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.

CANCER - HODGKINS DISEASE |
|
Hodgkin's lymphoma, formerly known as Hodgkin's disease, is a type of lymphoma described by Thomas Hodgkin in 1832, and characterized by the presence of Reed-Sternberg cells.
Hodgkin's Disease - A cancer of the immune system that is marked by the presence of a type of cell called the Reed Sternberg cell. Symptoms include the painless enlarged lymph nodes, spleen, or other immune tissue. Other symptoms include fever, weight loss, fatigue, or night sweats. Also called Hodgkin's lymphoma.

CANCER - LIVER |
|
Hepatocellular carcinoma (HCC, also called hepatoma or liver cancer) is a primary malignancy (cancer) of the liver. Most cases of HCC are secondary to either hepatitis infection (usually hepatitis B or C) or cirrhosis (alcoholism being the most common cause of hepatic cirrhosis). In countries where hepatitis is not endemic, most cancers in the liver are not primary HCC but metastasis (spread) of cancer from elsewhere in the body, e.g. the colon. Treatment options of HCC and prognosis are dependent on many factors but especially on tumor size and staging.

CANCER SKIN |
|
Skin cancer can occur anywhere on the body, but it is most common in skin that has been exposed to sunlight, such as the face, neck, hands, and arms. There are several types of cancer that start in the skin. The most common types are basal cell carcinoma and squamous cell carcinoma, which are nonmelanoma skin cancers. Melanoma is another form of skin cancer that is much more aggressive than basal cell skin cancer or squamous cell skin cancer.
|
CANCER - TESTICULAR |
|
Testicular cancer is a type of cancer that develops in the testicles, a part of the male reproductive system. In the United States, about 8,000 to 9,000 diagnoses of testicular cancer are made each year. Over his lifetime, a mans chance of getting testicular cancer is roughly 1 in 250 (four tenths of one percent, or 0.4%). It is most common among males aged 1540 years. Testicular cancer has one of the highest cure rates of all cancers: in excess of ninety percent; essentially one hundred percent if it has not spread. Even for the relatively few cases in which the cancer has spread widely, chemotherapy offers a cure rate of at least fifty percent.

CEREBRAL PALSY |
|
Cerebral palsy
is a term used to describe a group of chronic conditions affecting body movements and muscle coordination. It is caused by damage to one or more specific areas of the brain, usually occurring during fetal development, or during infancy. It can also occur before, during or shortly following birth. "Cerebral" refers to the brain and "Palsy" to a disorder of movement or posture.
|
CONSTRUCTION |
|
In project architecture and civil engineering, construction is the building or assembly of any infrastructure. Although this may be thought of as a single activity, in fact construction is a feat of multitasking. Normally the job is managed by the construction manager, supervised by the project manager, design engineer or project architect. While these people work in offices and make the most money, every construction project requires a large number of laborers to complete the physical task of construction.

COPYRIGHT - GENERAL |
|
Copyright is a set of exclusive rights granted by governments to regulate the use of a particular expression of an idea or information. At its most general, it is literally "the right to copy" an original creation. In most cases, these rights are of limited duration. The symbol for copyright is ©.
|
CORROSION EVALUATIONS |
|
Corrosion is deterioration of intrinsic properties in a material due to reactions with its environment. Weakening of steel due to oxidation of the iron atoms is a well-known example of electrochemical corrosion. This type of damage usually affects metallic materials, and typically produces oxide(s) and/or salt(s) of the original metal. Corrosion also includes the dissolution of ceramic materials and can refer to discoloration and weakening of polymers by the sun's ultraviolet light.
|
CRITICAL CARE |
|
Intensive Care Medicine or critical care medicine is concerned with providing greater than ordinary medical care and observation to people in a critical or unstable condition.
People requiring intensive care include those after major surgery, with severe head trauma, life-threatening acute illness, respiratory insufficiency, coma, haemodynamic insufficiency, severe fluid imbalance or with the failure of one or more of the major organ systems (life-critical systems or others).
|
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.

DOORS AND GATES |
|
A door is a generally floor-length opening in a wall (or other partition), often equipped with a hinged or sliding panel which can be moved to leave the opening accessible, or to close it more or less securely. Doors are nearly universal in structures of all kinds (especially houses and other buildings), allowing passage between inside and outside, or among internal rooms. Doors are also found in vehicles, cupboards, cages, etc. A gate is a point of entry to a space enclosed by walls, or an opening in a fence. Gates may prevent or control entry or exit, or they may be merely decorative.

ENGINEERING - CHEMICAL |
|
Chemical engineering is the application of science, in particular chemistry, physics and mathematics, to the process of converting raw materials or chemicals into more useful or valuable forms.
|
FARM EQUIPMENT |
|
Farm equipment is any kind of machinery used on a farm to help with farming. The best-known example of this kind of equipment is the tractor.
|
HELICOPTERS |
|
A helicopter is an aircraft which is lifted and propelled by one or more horizontal rotors (propellers). Helicopters are classified as rotary-wing aircraft to distinguish them from conventional fixed-wing aircraft. The word helicopter is derived from the Greek words helix (spiral) and pteron (wing). The engine-driven helicopter was invented by the Slovak inventor Jan Bahyl. The first stable, single-rotor, fully-controllable helicopter to enter large full-scale production was made by Igor Sikorsky in 1942.

HORSES |
|
The horse (Equus caballus or Equus ferus caballus) is a sizeable ungulate mammal, one of ten modern species of the genus Equus. Horses have long been one of the most economically important domesticated animals, and have played an important role in the transport of people and cargo for thousands of years. Most notably, horses can be ridden by a person perched on a saddle attached to the animal, and are also widely harnessed to pull objects like wheeled vehicles or plows. In some human cultures, horses are also widely used as a source of food. Though isolated domestication may have occurred as early as 4500 BC, clear evidence of widespread use by humans dates to no earlier than 2000 BC, as evidenced by the Sintashta chariot burials, thus firmly establishing the domestication of the horse.

INFECTIOUS DISEASE |
|
In medicine, infectious disease or communicable disease is disease caused by a biological agent such as by a virus, bacterium or parasite.

JEWELRY & GEMS |
|
Jewellery (Jewelry in American spelling) comprises ornamental objects worn by persons, typically made with gemstones and precious metals. Costume jewellery is made from less valuable materials. However, jewellery can and has been made out of almost every kind of material.
|
MARITAL DISSOLUTION - DIVORCE |
|
Divorce or dissolution of marriage is the ending of a marriage before the death of either spouse, which can be contrasted with an annulment, which is a declaration that a marriage is void, though the effects of marriage may be recognized in such unions, such as spousal support, child custody and distribution of property.

ONCOLOGY |
|
Oncology - The branch of medicine that deals with cancer and tumors, including study of their development, diagnosis, treatment, and prevention.
|
PHOTOGRAPHY |
|
Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally, the product of photography has been called a photograph. The term photo is a convenient abbreviation. Many people also call them pictures. In digital photography, the term image has begun to replace photograph. This term is neither more nor less correct than photograph, either in film or digital photography. (The term image is traditional in geometric optics.)

PROSTHETICS |
|
Prosthetics - In medicine, a prosthesis is an artificial extension that replaces a missing part of the body. Contrast with orthosis that supplements the body. Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital) or to supplement defective body parts.
|
PULMONARY MEDICINE |
|
Pulmonary Medicine - In medicine, pulmonology (aka pneumology) is the specialty that deals with diseases of the lungs and the respiratory tract. It is called chest medicine and respiratory medicine in some countries and areas.
|
REINSURANCE |
|
Reinsurance is a means by which an insurance company (called the reinsured, ceding company or cedant) shares the risk of loss with another insurance company (called the reinsurer).
|
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).
