Greyhound
The English Greyhound, or simply the Greyhound, is a breed of dog, a sighthound which has been bred for coursing, greyhound racing and hunting. Since the rise in large-scale adoption of retired racing Greyhounds, the breed has seen a resurgence in popularity as a family pet. Greyhounds are defined as a tall, muscular, smooth-coated, "S-shaped" type of sighthound with a long tail and tough feet. Greyhounds are a separate breed from other related sighthounds, such as the Italian greyhound. The Greyhound is a gentle and intelligent breed whose combination of long, powerful legs, deep chest, flexible spine, and slim build allows it to reach average race speeds exceeding . The Greyhound can reach a full speed of within , or six strides from the boxes, traveling at almost for the first of a race. Appearance Males are usually tall at the withers, and weigh on average .

Greyhound Racing
Greyhound racing is an organized, competitive sport in which greyhounds are raced around a track. There are two forms of greyhound racing, track racing (normally around an oval track) and coursing; the latter is now banned in most countries. Track racing uses an artificial lure (usually a form of windsock) that travels ahead of the greyhounds on a rail until the greyhounds cross the finish line. As with horse racing, greyhound races often allow the public to bet on the outcome. In many countries, greyhound racing is purely amateur and solely for enjoyment. In other countries, particularly Australia, Ireland, the United Kingdom, and the United States, greyhound racing is similar to horse racing in that it is part of the gambling industry. Animal rights and animal welfare groups have been critical of the welfare of greyhounds in the commercial racing industry for many years which has contributed to the reforms of the industries in recent years.

Greyhound Adoption
Greyhound adoption or Greyhound rescue programs focus on finding homes for Greyhounds who are no longer needed for racing. In some countries they live in kennels at the track. Currently, most Greyhound adoption programs are based in the United Kingdom, Canada, Australia, New Zealand and the United States. In Europe groups deal with dogs from a variety of sources; for example, in Spain, ex-hunting dogs are often in need of rescuing along with Greyhounds. Origins and work of the greyhound-adoption movement The Greyhound adoption movement grew out of a concern by a diverse community of people about the welfare among dogs in the commercial racing industry. Greyhound adoption was started by the greyhound industry in the late 1970s. Greyhound Pets of America (GPA) was established in 1987 for the purpose of finding homes for ex-racing greyhounds, and educating the public on the suitability and availability of greyhounds as pets. GPA is the largest non-profit greyhound adoption gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Italian Greyhound
The Italian Greyhound ( it, Piccolo levriero Italiano, italic=no) is an Italian breed of small sighthound. It may also be called the Italian Sighthound. History Small dogs of sighthound type have long been popular with nobility and royalty. Among those believed to have kept them are Frederick II, Duke of Swabia; members of the D'Este, Medici and Visconti families; the French kings Louis XI, Charles VIII, Charles IX, Louis XIII and Louis XIV; Frederick the Great of Prussia; Anne of Denmark; Catherine the Great and Queen Victoria. Dogs of this type have often been represented in paintings, notably by Giotto, Sassetta and Tiepolo. Dogs of this kind were taken in the first half of the nineteenth century to the United Kingdom, where they were known as Italian Greyhounds. The first volume of ''The Kennel Club Calendar and Stud Book'', published in 1874, lists forty of them. The first breed association was the Italian Greyhound Club, founded in Britain in 1900.

Hare Coursing
Hare coursing is the pursuit of hares with greyhounds and other sighthounds, which chase the hare by sight, not by scent. In some countries, it is a legal, competitive activity in which dogs are tested on their ability to run, overtake and turn a hare, rather than a form of hunting aiming at the capture of game. It has a number of variations in its rules around the world. Coursing can also be a form of hunting or pest control. It is a long-established hunting technique, practiced historically in England, especially with greyhounds or sighthound breeds, or with lurchers which are crossbred sighthounds. The sport grew in popularity in Europe during the 19th century, but has since experienced a decline due in part to the introduction of greyhound racing with betting, and animal welfare legislation. In recent decades, controversy has developed around hare coursing, with some viewing it as a cruel bloodsport. Hare coursing is illegal in the United Kingdom. In other countries, in ...

Irish Coursing Club
The Irish Coursing Club (ICC) is the national association for hare coursing in Ireland. Founded in 1916, it consists of 89 affiliated clubs on the Island of Ireland and acts as the official authority for the Irish variety of the sport. It solely controlled and administrated Greyhound racing in Ireland until the creation of the Irish Greyhound Board in 1958, however it still continues to do so in Northern Ireland. National Meetings The association holds two national meets, the National Meeting at the Clonmel Greyhound Stadium in County Tipperary in February, being the most important event in the coursing calendar, attracting 10,000 spectators, and claimed by its organisers to be worth up to €16 million for the local economy, and the Irish Cup at the County Limerick Coursing Club a few weeks afterwards. Conservation A study in 2010 by Dr Neil Reid at Queen's University Belfast found that the density of hares in ICC preserves was eighteen times higher than in the wi ...

Lure Coursing
Lure coursing is a sport for dogs that involves chasing a mechanically operated lure. Competition is typically limited to dogs of purebred sighthound breeds. The AKC has a pass/fail trial for all breeds called the Coursing Ability Test (CAT) and a timed 100 yard dash called Fast CAT where the dog's speed is converted to points. Lure course In lure coursing, dogs chase an artificial lure across a field, following a pattern that is meant to simulate live coursing. A typical lure course in the United States is between long. In Europe, as well as the rest of the world, the course length can be over 1000 meters, and often incorporates some obstacles or jumps. The course must have a minimum number of turns in order to simulate prey (the jack-rabbit or hare) changing direction in a chase. The fields can be fenced or not. If a dog is lure focused they will typically follow the lure from start to finish and not run off course. Dogs with some considerable lure experience, termed "lur ...

Sighthound
Sighthounds, also called gazehounds, are a type of dog, hounds that hunt primarily by sight and speed, rather than by scent and endurance as scent hounds do. Appearance These dogs specialize in pursuing prey, keeping it in sight, and overpowering it by their great speed and agility. They must be able to detect motion quickly, so they have keen vision. Sighthounds must be able to capture fast, agile prey such as deer, and hares, so they have a very flexible back and long legs for a long stride, a deep chest to support an unusually (compared to other dogs) large heart, very efficient lungs for both anaerobic and aerobic sprints, and a lean, wiry body to keep their weight at a minimum. Sighthounds have unique anatomical and physiological features likely due to intentional selection for hunting by speed and sight; laboratory studies have established reference intervals for hematology and serum biochemical profiles in sighthounds, some of which are shared by all sighthounds and s ...

Coursing
Coursing by humans is the pursuit of game or other animals by dogs—chiefly greyhounds and other sighthounds—catching their prey by speed, running by sight, but not by scent. Coursing was a common hunting technique, practised by the nobility, the landed and wealthy, as well as by commoners with sighthounds and lurchers. In its oldest recorded form in the Western world, as described by Arrian, it was a sport practised by all levels of society, which remained the case until Carolingian period forest law appropriated hunting grounds, or commons, for the king, the nobility, and other land owners. It then became a formalised competition, specifically on hare in Britain, practised under rules, the ''Laws of the Leash''. As a zoological term, it refers to predation by running down prey over long distances, as opposed to stalking, in which a stealthy approach is followed by a short burst of sprinting. Sport and hunting Animals coursed in hunting and sport include hares, foxes, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Osteosarcoma
An osteosarcoma (OS) or osteogenic sarcoma (OGS) (or simply bone cancer) is a cancerous tumor in a bone. Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid. Osteosarcoma is the most common histological form of primary bone sarcoma. It is most prevalent in teenagers and young adults. Signs and symptoms Many patients first complain of pain that may be worse at night, may be intermittent and of varying intensity and may have been occurring for a long time. Teenagers who are active in sports often complain of pain in the lower femur, or immediately below the knee. If the tumor is large, it can present as overt localised swelling. Sometimes a sudden fracture is the first symptom because the affected bone is not as strong as normal bone and may fracture abnormally with minor trauma. In cases of more deep-seated tumo ...

Oxidative Enzyme
An oxidative enzyme is an enzyme that catalyses an oxidation reaction. Two most common types of oxidative enzymes are peroxidases, which use hydrogen peroxide, and oxidases, which use molecular oxygen. They increase the rate at which ATP is produced aerobically. Oxidative enzymes are responsible for the browning of fruits like apples. When the surface of apples are exposed to the oxygen in the air, the oxidative enzymes like polyphenol oxidase and catechol oxidase oxidize the fruit (electrons are lost to the air). Such browning can be prevented by cooking the fruit or lowering the pH (which destroys, inactivates, or denatures the enzyme) or by preventing oxygen from getting to the surface (such as by covering the fruit). See also * Oxidoreductase In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor.
