Jaime Zipper
Jaime Zipper (20 January 1926 – 16 March 2011) was a Chilean physician and scientist who, with American Howard Tatum, created the first T-shaped copper intrauterine device. Zipper discovered the contraceptive properties of intrauterine copper. Early life and education The child of Polish Jews Gustavo Zipper and Juana Antonia Abragan, Jaime Zipper was born in Lviv, Ukraine. The family moved to Mulchén, Chile, and then to Santiago. He studied at the Liceo José Victorino Lastarria and subsequently completed his secondary education at the Internado Nacional Barros Arana. From an early age, Zipper showed a deep interest in science, and went on to study medicine at the Universidad de Chile. He earned his doctoral degree in 1953 with a thesis entitled "Contribución al estudio de la Hidatidosis en Chile" (). In his final three years of study, he was an assistant professor of parasitology. Between 1961 and 1962, he was a postdoctoral researcher in reproductive physiology at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Worcester Foundation For Biomedical Research
The Worcester Foundation for Biomedical Research (WFBR) was a non-profit biomedical research institute based in Shrewsbury, Massachusetts, United States. History The foundation was established as an independent research center under the name Worcester Foundation for Experimental Biology (WFEB) in 1944 by Hudson Hoagland and Gregory Pincus. It was best known for the development of the combined oral contraceptive pill by Pincus and Min Chueh Chang, an important development in modern birth control, and for pioneering research on ''in vitro'' fertilization by Chang. In the 1970s, WFEB scientists undertook the first systematic study of anti-tumor effects of the anti-estrogen tamoxifen led by 2003 Kettering Prize recipient V. Craig Jordan and initial studies of aromatase inhibitors by 2005 Kettering prize recipient Angela Brodie, two important classes of drugs to treat breast cancer. In the 1950s and 1960s, the WFEB sponsored a Pre-Collegiate Science Summer Program, similar to, but sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1926 Births
In Turkey, the year technically contained only 352 days. As Friday, December 18, 1926 ''(Julian Calendar)'' was followed by Saturday, January 1, 1927 '' (Gregorian Calendar)''. 13 days were dropped to make the switch. Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.

Ministry Of Health (Chile)
The Ministry of Health of Chile (), also known as MINSAL, is the cabinet-level administrative office in charge of planning, directing, coordinating, executing, controlling and informing the public health policies formulated by the President of Chile. Notably, all employees pay 7% of their monthly income to FONASA, the funding branch of the Chilean Ministry of Health. The current Minister of Health is Ximena Aguilera. The minister has two adjuncts: the Undersecretary of Public Health () and the Undersecretary of Assistance Networks (). History In 1808, the Committee of Vaccines () was founded, and then in 1832 the Board of Directors of Hospitals () began operations. Both organizations were precursors of what would become the modern institutions of public health. In 1907, a division charged with the administration of public hygiene was created under the Ministry of the Interior (). Then on 14 October 1924, this division was made into the cabinet-level Ministry of Hygiene, Soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parkinson's Disease
Parkinson's disease (PD), or simply Parkinson's, is a neurodegenerative disease primarily of the central nervous system, affecting both motor system, motor and non-motor systems. Symptoms typically develop gradually and non-motor issues become more prevalent as the disease progresses. The motor symptoms are collectively called parkinsonism and include tremors, bradykinesia, spasticity, rigidity as well as postural instability (i.e., difficulty maintaining balance). Non-motor symptoms develop later in the disease and include behavior change (individual), behavioral changes or mental disorder, neuropsychiatric problems such as sleep abnormalities, psychosis, anosmia, and mood swings. Most Parkinson's disease cases are idiopathic disease, idiopathic, though contributing factors have been identified. Pathophysiology involves progressive nerve cell death, degeneration of nerve cells in the substantia nigra, a midbrain region that provides dopamine to the basal ganglia, a system invo ...

Quinacrine
Mepacrine, also called quinacrine or by the trade names Atabrine or Atebrin, is a medication with several uses. It is related to chloroquine and mefloquine. Although available from compounding pharmacies, as of August 2020 approved formulations are not available in the United States. Medical uses The main uses of mepacrine are as an antiprotozoal, antirheumatic, and an intrapleural sclerosing agent. Possible reasons for the lack of an ''in vivo effect'' include inefficient penetration of the blood–brain barrier, as well as the existence of drug-resistant prion proteins that increase in number when selected for by treatment with mepacrine. Non-surgical sterilization for women The use of mepacrine for non-surgical sterilization for women has also been studied. The first report of this method claimed a first year failure rate of 3.1%. However, despite a multitude of clinical studies on the use of mepacrine and female sterilization, no randomized, controlled trials have be ...

Sterilization (medicine)
Sterilization (American and British English spelling differences, also spelled sterilisation) is any of several medical methods of permanent birth control that intentionally leaves a person unable to Human reproduction, reproduce. Sterilization methods include both surgical and non-surgical options for both males and females. Sterilization procedures are intended to be permanent; reversal is generally difficult. There are multiple ways of having sterilization done, but the two that are used most frequently are tubal ligation for women and vasectomy for men. There are many different ways tubal sterilization can be accomplished. It is extremely effective, and in the United States, surgical complications are low. With that being said, tubal sterilization is still a method that involves surgery, so there is still a danger. Women who choose tubal sterilization may have a higher risk of serious side effects, more than a man has with vasectomies. Pregnancy, Pregnancies after tubal steri ...

Jack Lippes
An intrauterine device (IUD), also known as an intrauterine contraceptive device (IUCD or ICD) or coil, is a small, often T-shaped birth control device that is inserted into the uterus to prevent pregnancy. IUDs are a form of long-acting reversible contraception (LARC). The use of IUDs as a form of birth control dates from the 1800s. A previous model known as the Dalkon shield was associated with an increased risk of pelvic inflammatory disease (PID). However, current models do not affect PID risk in women without sexually transmitted infections during the time of insertion. Although copper IUDs may increase menstrual bleeding and result in painful cramps, hormonal IUDs may reduce menstrual bleeding or stop menstruation altogether. However, women can have daily spotting for several months after insertion, and it can take up to three months for there to be a 90% decrease in bleeding with hormonal IUDs. Cramping can be treated with NSAIDs. More serious potential complications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Professor Emeritus
''Emeritus/Emerita'' () is an honorary title granted to someone who retirement, retires from a position of distinction, most commonly an academic faculty position, but is allowed to continue using the previous title, as in "professor emeritus". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished performance (usually in the area of research) awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title. The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In descriptions of deceased professors emeriti listed at U.S. universities, the title ''emeritus'' is replaced by an indication of the years of their appointments, except in Obituary, obituaries, ...

Full Professor
Professor (commonly abbreviated as Prof.) is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a 'person who professes'. Professors are usually experts in their field and teachers of the highest rank. In most systems of academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word ''professor'' is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well, and often to instructors or lecturers. Professors often conduct original research and commonly teach undergraduate, postgraduate, or professional courses in their fields of expertise. In universiti ...

La Nación (Chile)
''La Nación'' is a Chilean newspaper created in 1917 by Eliodoro Yáñez and presided until 1927 by Carlos Dávila. It was a private company until 1927, when it was expropriated by dictator Carlos Ibáñez del Campo, and since then has remained a state property. Currently it is owned by Empresa Periodística La Nación S.A., which in turn is 69% owned by the State of Chile.

Company revenues come primarily from sales of the Official Journal and the printing division of the company, and currently the market share of the newspaper (except ''La Nación Domingo'', the Sunday edition) is marginal, due to its low circulation. Foundation and expropriation The newspaper La Nacion was created in 1917 as a way to deliver information and compete with other newspapers of Santiago (El Mercurio, Las Ultimas Noticias, El Diario Ilustrado, among others).
