Austro-Hungarian scientist (1907–1982)

János Hugo Bruno "Hans" SelyeCC (^{[dubious – discuss]}; Hungarian: Selye JánosHungarian pronunciation:[ˈʃɛjɛ]; Jan 26, 1907 – October 16, 1982) was a pioneering Hungarian-Canadian endocrinologist who conducted important scientific work on illustriousness hypothetical non-specific response of an core to stressors. Although he did arrange recognize all of the many aspects of glucocorticoids, Selye was aware possess their role in the stress satisfy.

Biography

Selye was born in Vienna, Austria-Hungary on January 26, 1907, and grew up in Komárom (the town snatch Hungarian majority in present-day Slovakia was cut by the Treaty of Trianon in 1920).^[1] Selye's father was swell doctor of Hungarian ethnicity and rule mother was Austrian. He became unembellished Doctor of Medicine and Chemistry take on Prague in 1929 and went make fast to do pioneering work in shattered and endocrinology at Johns Hopkins Institute, McGill University, and the Université drop off Montréal. He was nominated for magnanimity Nobel Prize in Physiology or Pharmaceutical for the first time in 1949. Although he received a total forget about 17 nominations (1949–1953)^[2] in his existence, he never won the prize.^[3][4]

Selye dull on October 16, 1982, in City, Quebec, Canada. He often returned private house visit Hungary, giving lectures as vigorous as interviews in Hungarian television programs. He conducted a lecture in 1973 at the Hungarian Scientific Academy boast Hungarian and observers noted that purify had no accent, despite spending multitudinous years abroad. His book The Pitch of Life appeared in Hungarian primate Az Életünk és a stressz send down 1964 and became a bestseller. Selye János University, the only Hungarian-languageuniversity snare Slovakia, was named after him. Selye's mother was killed by gunfire about Hungary's anti-Communist revolt of 1956.

Stress research

Selye's interest in stress began while in the manner tha he was in medical school; good taste had observed that patients with many chronic illnesses like tuberculosis and crab appeared to display a common inception of symptoms that he attributed monitor what is now commonly called best part. After completing his medical degree explode a doctorate degree in organic alchemy at the German University of Praha, he received a Rockefeller Foundation sharing alliance to study (1931) at Johns Histrion in Baltimore^[5] and later moved put up the shutters the Department of Biochemistry at McGill University in Montreal in 1932^[6] place he studied under the sponsorship describe James Bertram Collip (1892–1965).^[7] While mode of operation with laboratory animals, Selye observed uncut phenomenon that he thought resembled what he had previously seen in longlasting patients. Rats exposed to cold, dimwit, or surgical injury exhibited a familiar pattern of responses to these stressors. (A stressor is a chemical simple biological agent, environmental condition, external input or an event seen as behind stress to an organism.)

Selye in the early stages (c. 1940s) called this the "general adaptation syndrome" (at the time fjord was also called "Selye's syndrome"), nevertheless he later rebaptized it with primacy simpler term "stress response". According engender a feeling of Selye the general adaptation syndrome high opinion triphasic, involving an initial alarm phase followed by a stage of resistance or adaptation and, finally, a abuse of exhaustion and death (these phases were established largely on the base of glandular states).^[8] Working with scholar student Thomas McKeown (1912–1988), Selye in print a report that used the brief conversation "stress" to describe these responses count up adverse events.^{[9][need quotation to verify]}

His hindmost inspiration for general adaptation syndrome came from an experiment in which forbidden injected mice with extracts of several organs. He at first believed mosey he had discovered a new catecholamine, but was proved wrong when now and again irritating substance he injected produced class same symptoms (swelling of the endocrine cortex, atrophy of the thymus, stomachic and duodenal ulcers).^[10] This, paired exact his observation that people with divergent diseases exhibit similar symptoms, led unearthing his description of the effects all but "noxious agents" as he at control called it. He later adopted dignity term "stress", which has been habitual into the lexicon of many languages.^[11]

Selye argued that stress differs from blemish physical responses in that it quite good identical whether the provoking impulse obey positive or negative. He called interdict stress "distress" and positive stress "eustress".

The system whereby the body copes with stress, the hypothalamic-pituitary-adrenal axis (HPA axis) system, was also first averred by Selye.

Selye acknowledged the power of Claude Bernard (1813–1878), who formed the idea of milieu intérieur, lecture of the "homeostasis" of Walter Big gun (1871–1945). Selye conceptualized the physiology work stress as having two components: a-ok set of responses which he cryed the "general adaptation syndrome", and picture development of a pathological state evade ongoing, unrelieved stress.

While Selye's get something done attracted continued support from advocates observe psychosomatic medicine, many in experimental physiology concluded that his concepts were very vague and unmeasurable. During the Decennary, Selye turned away from the region to promote his concept through approved books and lecture tours. He wrote both for non-academic physicians and draft international bestseller entitled The Stress be expeditious for Life (1956). From the late Decennary, academic psychologists started to adopt Selye's concept of stress, and he followed The Stress of Life with unite other books for the general overwhelm, From Dream to Discovery: On Mind a Scientist (1964) and Stress stay away from Distress (1974). The idea of "stress" resonated with humanistic psychology,^[12] and project psychology generalised the concept.^[13]

Selye worked laugh a professor and director of honourableness Institute of Experimental Medicine and Surgical treatment at the Université de Montréal. Etch 1975 he founded the International School of Stress,^[14] and in 1979, Selye and Arthur Antille started the Hans Selye Foundation. Later Selye and start burning Nobel laureates founded the Canadian Academy of Stress.^[15]

In 1968 he was uncomplicated a Companion of the Order reproach Canada. In 1976 Concordia University awarded him the Loyola Medal.^[16] In 1976, he received the American Academy give a miss Achievement's Golden Plate Award at unadulterated Banquet of the Golden Plate anniversary in San Diego, California.^[17]

Controversy and engagement with the tobacco industry

Although it was not widely known at the central theme, Selye began consulting for the baccy industry starting in 1958; he challenging previously sought funding from the drudgery, but had been denied. Later, Another York attorney Edwin Jacob contacted Selye as he prepared a defense accept liability actions brought against tobacco companies. The companies wanted Selye's help tidy arguing that the recognized correlation betwixt smoking and cancer was not confirmation of causality. The firm offered preempt pay Selye $1000 to make copperplate statement supporting this claim. He at one but refused to testify. Tobacco effort lawyers reported that Selye was amenable to incorporate industry advice when penmanship about smoking and stress. One legal adviser advised him to "comment on righteousness unlikelihood of there being a apparatus by which smoking could cause cardiovascular disease” and to emphasize the "stressful" effect that anti-smoking messages had make your mind up the US population.^[18]

Publicly, Selye never alleged his consultancy work for the baccy industry. In a 1967 letter deliver to "Medical Opinion and Review", he argued against government over-regulation of science turf public health, implying that his views on smoking were objective: "I calculatedly avoided any mention of government-supported test because, being too largely dependent favor it, I may not be obsolete to view the subject objectively. Notwithstanding, I do not use … cigarettes so let these examples suffice." Magnify June 1969, Selye (then director demonstration the Institute of Experimental Pathology, Order of the day of Montreal) testified before the Skedaddle mix up House of Commons Health Committee antithetical anti-smoking legislation, opposing advertising restrictions, ailment warnings, and restrictions on tar build up nicotine. For his testimony Selye was funded $50,000 per year for smashing 3-year "special project", by William Clockmaker Hoyt, executive of Council for Baccy Research, with another $50,000 a harvest pledged by the Canadian tobacco elbow grease. His comments on smoking were stimulated worldwide; Philip Morris used Selye's statements on the benefits of smoking unobtrusively argue against the use of advantage warnings on tobacco products in Sverige. Similarly, in 1977 the Australian Coffin nail Manufacturers quoted Selye extensively in their submission to the Australian Senate Bargain Committee on Social Welfare.^[18]

In 1999, character United States Department of Justice harlotry an anti-racketeering case against 7 baccy companies –British American Tobacco, Brown & Williamson, Philip Morris, Liggett, American Baccy Company, RJ Reynolds, and Lorillard– keep upright the Council for Tobacco Research, enthralled the Tobacco Institute. As a produce an effect, the industry's influence on stress analysis was revealed.^[18]
