Anoplocephala Manubriata
''Anoplocephala manubriata'' is a host-specific tapeworm, or ''cestode'', that parasitizes African (''Loxodonta africana'') and Asian (''Elephas maximus'') elephants. These parasites require intermediate and definitive hosts to complete its life cycle. ''A. manubriata'' causes gastrointestinal inflammation in elephants. When ingested in the elephant, the cestode is attached to the intestinal mucosae. The life cycle of ''A. manubriata'' have not been completely elucidated, however studies have shown through examining oribatid mites from a dung pile near an elephant site that an immature stage exists. The study concluded at least five species were contained at least one immature life stage of the cestode. Studies have shown that ''Anoplocephala manubriata'' is closely related to another ''Anoplocephala'' species called ''Anoplocephala perfoliata'', which is a host-specific tapeworm to horses. Phylogenetic analysis of the second internal transcribed spacer region (ITS-2), a portio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis-Joseph Alcide Railliet
Louis-Joseph Alcide Railliet (also known as Alcide Railliet, born 11 March 1852 at La Neuville-lès-Wasigny in the Ardennes – died 25 December 1930) was a French veterinarian and helminthologist. Professor at the Veterinary School of Alfort, he is considered one of the founders of modern parasitology and wrote several books of veterinary parasitology. He chaired the Société zoologique de France in 1891. He was a member of the French Académie Nationale de Médecine, from 29 December 1896 to his death. He received the Legion of Honor. Tributes Railliet's name is honoured by several genera: '' Raillietia'' (Acari), '' Raillietina'' ( Cestodes), '' Raillietascaris'', '' Raillietnema'' and '' Raillietstrongylus'' (Nematodes), '' Raillietiella'' (Pentastomida), and the Acari family Raillietiidae. Numerous species were named after Railliet, such as ''Amidostomum raillieti, Angiocaulus raillieti, Aspidodera raillieti, Conoweberia raillieti, Eucoleus raillieti, Haemostrongylus ...

Cytochrome C Oxidase Subunit I
Cytochrome c oxidase I (COX1) also known as mitochondrially encoded cytochrome c oxidase I (MT-CO1) is a protein that in humans is encoded by the ''MT-CO1'' gene. In other eukaryotes, the gene is called ''COX1'', ''CO1'', or ''COI''. Cytochrome c oxidase I is the main subunit of the cytochrome c oxidase complex. Mutations in MT-CO1 have been associated with Leber's hereditary optic neuropathy (LHON), acquired idiopathic sideroblastic anemia, Complex IV deficiency, colorectal cancer, sensorineural deafness, and recurrent myoglobinuria. Structure One of 37 mitochondrial genes, the ''MT-CO1'' gene is located from nucleotide pairs 5904 to 7444 on the guanine-rich heavy (H) section of mtDNA. The gene product is a 57 kDa protein composed of 513 amino acids. Function Cytochrome c oxidase subunit I (CO1 or MT-CO1) is one of three mitochondrial DNA (mtDNA) encoded subunits (MT-CO1, MT-CO2, MT-CO3) of respiratory complex IV. Complex IV is the third and final enzyme of the electron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autopsy
An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode, and manner of death or to evaluate any disease or injury that may be present for research or educational purposes. (The term "necropsy" is generally reserved for non-human animals). Autopsies are usually performed by a specialized medical doctor called a pathologist. In most cases, a medical examiner or coroner can determine the cause of death. However, only a small portion of deaths require an autopsy to be performed, under certain circumstances. Purposes of performance Autopsies are performed for either legal or medical purposes. Autopsies can be performed when any of the following information is desired: * Determine if death was natural or unnatural * Injury source and extent on the corpse * Manner of death must be determined * Post mortem interval * Determining the deceas ...

Geophagia
Geophagia (), also known as geophagy (), is the intentional practice of eating earth or soil-like substances such as clay, chalk, or termite mounds. It is a behavioural adaptation that occurs in many non-human animals and has been documented in more than 100 primate species. Geophagy in non-human primates is primarily used for protection from parasites, minerals supplements and helps metabolize toxic compounds from leaves. Geophagy also occurs in humans and is most commonly reported among children and pregnant women. Human geophagia is a form of pica – the craving and purposive consumption of non-food items – and is classified as an eating disorder in the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM) if not socially or culturally appropriate. Sometimes geophagy is a consequence of carrying a hookworm infection. Although its etiology remains unknown, geophagy has many potential adaptive health benefits as well as negative consequences. Animals Geophagia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anorexia Nervosa
Anorexia nervosa, often referred to simply as anorexia, is an eating disorder characterized by low weight, food restriction, body image disturbance, fear of gaining weight, and an overpowering desire to be thin. ''Anorexia'' is a term of Greek origin: ''an-'' (ἀν-, prefix denoting negation) and ''orexis'' (ὄρεξις, "appetite"), translating literally to "a loss of appetite"; the adjective ''nervosa'' indicating the functional and non-organic nature of the disorder. ''Anorexia nervosa'' was coined by Gull in 1873 but, despite literal translation, the feeling of hunger is frequently present and the pathological control of this instinct is a source of satisfaction for the patients. Individuals with anorexia nervosa have a fear of being overweight or being seen as such, although they are in fact underweight. The DSM-5 describes this perceptual symptom as "disturbance in the way in which one's body weight or shape is experienced". In research and clinical settings, thi ...

Fecundity
Fecundity is defined in two ways; in human demography, it is the potential for reproduction of a recorded population as opposed to a sole organism, while in population biology, it is considered similar to fertility, the natural capability to produce offspring, measured by the number of gametes (eggs), seed set, or asexual propagules. Superfecundity refers to an organism's ability to store another organism's sperm (after copulation) and fertilize its own eggs from that store after a period of time, essentially making it appear as though fertilization occurred without sperm (i.e. parthenogenesis). Human demography Human demography considers only human fecundity, at its culturally differing rates, while population biology studies all organisms. The term ''fecundity'' in population biology is often used to describe the rate of offspring production after one time step (often annual). In this sense, fecundity may include both birth rates and survival of young to that time step. Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
