David Landsborough Thomson
David Landsborough Thomson F.R.S.C., (1901 - 1964) was a Canadian biochemist, best known for the co-discovery of Adrenocorticotropic hormone (adreno-cortical thyroid hormone or ACTH) and as the vice-principal of McGill University. ACTH was co-discovered by Evelyn M. Anderson, James Bertram Collip and Thomson. In a paper published in 1933, they explained its function in the body. Born in Scotland, Thomson earned BSc and MA degrees from the University of Aberdeen, then a PhD in biochemistry from Cambridge University under the eye of Nobel laureate Frederick Gowland Hopkins. After further studies in Europe, he moved to Montreal, joining the McGill faculty in 1928. At McGill, he was Gilman Cheney Professor of Biochemistry from 1937 to 1960, dean of the faculty of graduate studies and research from 1942 to 1963, and the vice-principal from 1955 to 1963. He served on the National Research Council of Canada, the Defence Research Board and the Scientific Research Bureau of Quebec. He rec ...

Adrenocorticotropic Hormone
Adrenocorticotropic hormone (ACTH; also adrenocorticotropin, corticotropin) is a polypeptide tropic hormone produced by and secreted by the anterior pituitary gland. It is also used as a medication and diagnostic agent. ACTH is an important component of the hypothalamic-pituitary-adrenal axis and is often produced in response to biological stress (along with its precursor corticotropin-releasing hormone from the hypothalamus). Its principal effects are increased production and release of cortisol by the cortex of the adrenal gland. ACTH is also related to the circadian rhythm in many organisms. Deficiency of ACTH is an indicator of secondary adrenal insufficiency (suppressed production of ACTH due to an impairment of the pituitary gland or hypothalamus, cf. hypopituitarism) or tertiary adrenal insufficiency (disease of the hypothalamus, with a decrease in the release of corticotropin releasing hormone (CRH)). Conversely, chronically elevated ACTH levels occur in primary ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Citizenship Act 1946
The ''Canadian Citizenship Act'' (french: Loi sur la citoyenneté canadienne) was a statute passed by the Parliament of Canada in 1946 which created the legal status of Canadian citizenship. The Act defined who were Canadian citizens, separate and independent from the status of the British subject and repealed earlier Canadian legislation relating to Canadian nationals and citizens as sub-classes of British subject status. The Act came into force on 1 January 1947 and was in force for thirty years, until replaced on 15 February 1977 by a new statute, the ''Canadian Citizenship Act, 1976'', now known as the ''Citizenship Act''. Pre-1947: British subjects and Canadian citizens The status of "Canadian citizen" was originally created under the ''Immigration Act, 1910''S.C. 1910, c. 27 to designate those British subjects who were born, naturalized, or domiciled in Canada. All other British subjects required permission to land. "Domicile" was defined as having been resident in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alumni Of The University Of Aberdeen
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating (Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the s ...

Canadian Biochemists
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vitamin B Complex
B vitamins are a class of water-soluble vitamins that play important roles in cell metabolism and synthesis of red blood cells. Though these vitamins share similar names (B1, B2, B3, etc.), they are chemically distinct compounds that often coexist in the same foods. In general, dietary supplements containing all eight are referred to as a vitamin B complex. Individual B vitamin supplements are referred to by the specific number or name of each vitamin, such as B1 for thiamine, B2 for riboflavin, and B3 for niacin. Some are more commonly recognized by name than by number, for example pantothenic acid, biotin, and folate. Each B vitamin is either a cofactor (generally a coenzyme) for key metabolic processes or is a precursor needed to make one and is thus an essential nutrient. List of B vitamins Note: other substances once thought to be vitamins were given numbers in the B-vitamin numbering scheme, but were subsequently discovered to be either not essential for life or manufac ...

Vitamins
A vitamin is an organic molecule (or a set of molecules closely related chemically, i.e. vitamers) that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet. Vitamin C can be synthesized by some species but not by others; it is not a vitamin in the first instance but is in the second. The term ''vitamin'' does not include the three other groups of essential nutrients: minerals, essential fatty acids, and essential amino acids. Most vitamins are not single molecules, but groups of related molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. Some sources list fourteen vitamins, by including choline, but major health organizations list thirteen: vitamin A (as all-''trans''-retinol, all- ...

Endocrinology
Endocrinology (from '' endocrine'' + '' -ology'') is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones. It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction, and sensory perception caused by hormones. Specializations include behavioral endocrinology and comparative endocrinology. The endocrine system consists of several glands, all in different parts of the body, that secrete hormones directly into the blood rather than into a duct system. Therefore, endocrine glands are regarded as ductless glands. Hormones have many different functions and modes of action; one hormone may have several effects on different target organs, and, conversely, one target ...

Hans Selye
János Hugo Bruno "Hans" Selye (; hu, Selye János; January 26, 1907 – October 16, 1982) was a pioneering Hungarian-Canadian endocrinologist who conducted important scientific work on the hypothetical non-specific response of an organism to stressors. Although he did not recognize all of the many aspects of glucocorticoids, Selye was aware of their role in the stress response. Charlotte Gerson considers him the first to demonstrate the existence of biological stress. Biography Selye was born in Vienna, Austria-Hungary on January 26, 1907 and grew up in Komárom (the town with Hungarian majority in present day Slovakia was cut by the Treaty of Trianon in 1920). Selye's father was a doctor of Hungarian ethnicity and his mother was Austrian. He became a Doctor of Medicine and Chemistry in Prague in 1929 and went on to do pioneering work in stress and endocrinology at Johns Hopkins University, McGill University, and the Université de Montréal. He was nominated for the Nobel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
