Horse Cloning
Horse cloning is the process of obtaining a horse with genes identical to that of another horse, using an artificial Fertilisation, fertilization technique. Interest in this technique began in the 1980s. The Haflinger foal Prometea, the first living cloned horse, was obtained in 2003 in an Italian laboratory. Over the years, the technique has improved. It is mainly used on high-performance but castrated or infertile animals, for reproductive cloning. These horses are then used as breeding stock. Horse cloning is only mastered by a handful of laboratories worldwide, notably in France, Argentina, North America and China. The technique is limited by the fact that some differences remain between the original and its clone, due to the influence of mitochondrial DNA. Reproductive cloning of the Pieraz and Quidam de Revel horses began in 2005. The International Federation for Equestrian Sports (FEI by its acronym in French) decided to ban clones from competition in 2007, before authorizin ...

Gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as g ...

CRC Press
The CRC Press, LLC is an American publishing group that specializes in producing technical books. Many of their books relate to engineering, science and mathematics. Their scope also includes books on business, forensics and information technology. CRC Press is now a division of Taylor & Francis, itself a subsidiary of Informa. History The CRC Press was founded as the Chemical Rubber Company (CRC) in 1903 by brothers Arthur, Leo and Emanuel Friedman in Cleveland, Ohio, based on an earlier enterprise by Arthur, who had begun selling rubber laboratory aprons in 1900. The company gradually expanded to include sales of laboratory equipment to chemists. In 1913 the CRC offered a short (116-page) manual called the ''Rubber Handbook'' as an incentive for any purchase of a dozen aprons. Since then the ''Rubber Handbook'' has evolved into the CRC's flagship book, the ''CRC Handbook of Chemistry and Physics''. In 1964, Chemical Rubber decided to focus on its publishing ventures ...

Michael Whitaker
Michael Whitaker (born 17 March 1960) is a British Olympic equestrian rider, who competes in the sport of show jumping. He was ranked 5th by the British Showjumping Association in March 2014. Career Younger brother of John Whitaker, Michael began competing on ponies at the age of 5. At the age of 16, he made his debut in international competitions and in 1980 he became the second youngest winner of the Hickstead Derby, at the age of 20. In September 1993 he took over from his brother John as the internationally top-ranked show jumping rider. In 2009 Whitaker was banned from competition for four months after his stallion Tackeray tested positive for a synthetic hormone altrenogest during a competition in France. Altrenogest is a female hormone that Whitaker claimed was present in the sample due to a mix up in feed buckets. Whitaker was found to be negligent for the positive test. Personal life Born and raised on his parents' farm in Yorkshire. He and his three brothers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Veterinarian
A veterinarian (vet), also known as a veterinary surgeon or veterinary physician, is a medical professional who practices veterinary medicine. They manage a wide range of health conditions and injuries in non-human animals. Along with this, vets also play a role in animal reproduction, animal health management, conservation, husbandry and breeding and preventive medicine like animal nutrition, vaccination and parasitic control as well as biosecurity and zoonotic disease surveillance and prevention. Description In many countries, the local nomenclature for a veterinarian is a regulated and protected term, meaning that members of the public without the prerequisite qualifications and/or licensure are not able to use the title. This title is selective in order to produce the most knowledgeable veterinarians that pass these qualifications. In many cases, the activities that may be undertaken by a veterinarian (such as treatment of illness or surgery in animals) are restricted ...

In Vitro Fertilisation
In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating an individual's ovulatory process, removing an ovum or ova (egg or eggs) from their ovaries and letting sperm fertilise them in a culture medium in a laboratory. After the fertilised egg ( zygote) undergoes embryo culture for 2–6 days, it is transferred by catheter into the uterus, with the intention of establishing a successful pregnancy. IVF is a type of assisted reproductive technology used for infertility treatment, gestational surrogacy, and, in combination with pre-implantation genetic testing, avoiding transmission of genetic conditions. A fertilised egg from a donor may implant into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries have banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restric ...

Medical Ultrasound
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g. distances and velocities) or to generate an informative audible sound. Its aim is usually to find a source of disease or to exclude pathology. The usage of ultrasound to produce visual images for medicine is called medical ultrasonography or simply sonography. The practice of examining pregnant women using ultrasound is called obstetric ultrasonography, and was an early development of clinical ultrasonography. Ultrasound is composed of sound waves with frequencies which are significantly higher than the range of human hearing (>20,000 Hz). Ultrasonic images, also known as sonograms, are created by sending pulses of ultrasound into tissue using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
