Bloat (ruminant)
Ruminal tympany, also known as ruminal bloat, is a disease of ruminant animals, characterized by an excessive volume of gas in the rumen. Ruminal tympany may be primary, known as frothy bloat, or secondary, known as free-gas bloat. In the rumen, food eaten by the ruminant is fermentation, fermented by microbes. This fermentation process continually produces gas, the majority of which is expelled from the rumen by eructation (burping). Ruminal tympany occurs when this gas becomes trapped in the rumen. In frothy bloat (primary ruminal tympany), the gas produced by fermentation is trapped within the fermenting material in the rumen, causing a build up of foam which cannot be released by burping. In cattle, the disease may be triggered after an animal eats a large amount of easily fermenting plants, such as legumes, alfalfa, red clover, or white clover. Some legumes, such as sainfoin, birdsfoot trefoil and cicer milkvetch are not associated with causing bloat in cattle. In feedlot catt ...

Ruminant
Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.

Trocar
A trocar (or trochar) is a medical device, medical or veterinary medicine, veterinary device used in minimally invasive surgery. Trocars are typically made up of an Wiktionary:awl, awl (which may be metal or plastic with a pointed or tapered tip), a cannula (essentially a rigid hollow tube) and often a seal (mechanical), seal. Some trocars also include a valve mechanism to allow for insufflation (medicine), insufflation. Trocars are designed for placement through the chest and abdominal walls during thoracoscopy, thoracoscopic and laparoscopic surgery, and each trocar functions as a portal (architecture), portal for the subsequent insertion of other endoscopic instruments such as forceps, grasper, surgical scissors, scissors, surgical staple, stapler, electrocautery, suction (medicine), suction tip, etc. — hence the more commonly used colloquial jargon "port". Trocars also allow passive evacuation of excess gas or fluid from organs within the body. Etymology The word ''trocar' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All Creatures Great And Small (1978 TV Series)
''All Creatures Great and Small'' is a British television series made by the BBC and based on the books of the British veterinary surgeon Alf Wight, who wrote under the pseudonym James Herriot. Set in the Yorkshire Dales and beginning in the mid-1930s, it stars Christopher Timothy as Herriot, Robert Hardy as Siegfried Farnon (based on Donald Sinclair), the proprietor of the Skeldale House surgery, and Peter Davison as Siegfried's "little brother", Tristan (based on Brian Sinclair). Herriot's wife, Helen (based on Joan Wight), was initially played by Carol Drinkwater and in the later series by Lynda Bellingham. The series had two runs: the original (1978 to 1980, based directly on Herriot's books) was for three series; the second (1988 to 1990, filmed with original scripts but generally regarded as a continuation of the 1978 series) for four. The supporting cast, both recurring and one-offs, numbers over 600, most of whom appear as farmers or clients of the surgery. The series ...

James Herriot
James Alfred Wight (3 October 1916 – 23 February 1995), better known by his pen name James Herriot, was a British veterinary surgeon and author. Born in Sunderland, Wight graduated from Glasgow Veterinary College in 1939, returning to England to become a veterinary surgeon in Yorkshire, where he practised for almost 50 years. He is best known for writing a series of eight books set in the 1930s–1950s Yorkshire Dales about veterinary practice, animals, and their owners, which began with ''If Only They Could Talk'', first published in 1970. Over the decades, the series of books has sold some 60 million copies. The franchise based on his writings was very successful. In addition to the books, there have been several television and film adaptations of Wight's books, including the 1975 film '' All Creatures Great and Small''; a BBC television series of the same name, which ran 90 episodes; and a 2020 UK Channel 5 series, also of the same name.

Thomas Hardy
Thomas Hardy (2 June 1840 – 11 January 1928) was an English novelist and poet. A Literary realism, Victorian realist in the tradition of George Eliot, he was influenced both in his novels and in his poetry by Romanticism, including the poetry of William Wordsworth. He was highly critical of much in Victorian era, Victorian society, especially on the declining status of rural people in Britain such as those from his native South West England. While Hardy wrote poetry throughout his life and regarded himself primarily as a poet, his first collection was not published until 1898. Initially, he gained fame as the author of novels such as ''Far from the Madding Crowd'' (1874), ''The Mayor of Casterbridge'' (1886), ''Tess of the d'Urbervilles'' (1891) and ''Jude the Obscure'' (1895). During his lifetime, Hardy's poetry was acclaimed by younger poets (particularly the Georgian Poetry, Georgians) who viewed him as a mentor. After his death his poems were lauded by Ezra Pound, W. H. Au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histamine
Histamine is an organic nitrogenous compound involved in local immune responses communication, as well as regulating physiological functions in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. Discovered in 1910, histamine has been considered a local hormone ( autocoid) because it is produced without involvement of the classic endocrine glands; however, in recent years, histamine has been recognized as a central neurotransmitter. Histamine is involved in the inflammatory response and has a central role as a mediator of itching. As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues. It consists of an imidazole ring attached to an ethylamine chain; under physiological conditions, the amino grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactic Acid
Lactic acid is an organic acid. It has the molecular formula C3H6O3. It is white in the solid state and it is miscible with water. When in the dissolved state, it forms a colorless solution. Production includes both artificial synthesis as well as natural sources. Lactic acid is an alpha-hydroxy acid (AHA) due to the presence of a hydroxyl group adjacent to the carboxyl group. It is used as a synthetic intermediate in many organic synthesis industries and in various biochemical industries. The conjugate base of lactic acid is called lactate (or the lactate anion). The name of the derived acyl group is lactoyl. In solution, it can ionize by a loss of a proton to produce the lactate ion . Compared to acetic acid, its p''K'' is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group. Lactic acid is chiral, consisting of two en ...

Acidosis
Acidosis is a biological process producing hydrogen ions and increasing their concentration in blood or body fluids. pH is the negative log of hydrogen ion concentration and so it is decreased by a process of acidosis. Acidemia The term acidemia describes the state of low blood pH, when arterial pH falls below 7.35 (except in the fetus – see below) while ''acidosis'' is used to describe the processes leading to these states. The use of acidosis for a low pH creates an ambiguity in its meaning. The difference is important where a patient has factors causing both acidosis and alkalosis, wherein the relative severity of both determines whether the result is a high, low, or normal pH. Alkalemia occurs at a pH over 7.45. Arterial blood gas analysis and other tests are required to separate the main causes. In certain situations the main cause is clear. For instance, a diabetic with ketoacidosis is a recognizable case where the main cause of acidemia is essentially obvious. ...

Antihistamine
Antihistamines are drugs which treat allergic rhinitis, common cold, influenza, and other allergies. Typically, people take antihistamines as an inexpensive, generic (not patented) drug that can be bought without a prescription and provides relief from nasal congestion, sneezing, or hives caused by pollen, dust mites, or animal allergy with few side effects. Antihistamines are usually for short-term treatment. Chronic allergies increase the risk of health problems which antihistamines might not treat, including asthma, sinusitis, and lower respiratory tract infection. Consultation of a medical professional is recommended for those who intend to take antihistamines for longer-term use. Although the general public typically uses the word "antihistamine" to describe drugs for treating allergies, physicians and scientists use the term to describe a class of drug that opposes the activity of histamine receptors in the body. In this sense of the word, antihistamines are subc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sodium Bicarbonate
Sodium bicarbonate ( IUPAC name: sodium hydrogencarbonate), commonly known as baking soda or bicarbonate of soda (or simply “bicarb” especially in the UK) is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation ( Na+) and a bicarbonate anion (). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda ( sodium carbonate). The natural mineral form is nahcolite, although it is more commonly found as a component of the mineral trona. As it has long been known and widely used, the salt has many different names such as baking soda, bread soda, cooking soda, brewing soda and bicarbonate of soda and can often be found near baking powder in stores. The term ''baking soda'' is more common in the United States, while ''bicarbonate of soda'' is more common in Australia, the United Kingdom, and New Zealand.
