Bernhard Witkop
Bernhard Witkop (May 9, 1917 in Freiburg, Baden – November 22, 2010 in Chevy Chase, Maryland) was a German-born American organic chemist who worked for the National Institutes of Health (NIH) for 37 years. During those years, Dr. Witkop – along with his recruit, the late Dr. John Daly, and others – discovered the NIH shift, a term describing the movement of hydrogen, deuterium or tritium to adjacent carbons on aromatic rings during oxidation, a process key in developing many therapies. He also helped to develop selective methods for the non-enzymatic cleavage of proteins, which enabled the sequencing of amino acids in proteins as large as immunoglobulin, a method later used in the production of human insulin. Dr. Witkop also helped pioneer the NIH Visiting Fellow Program. Among other foreign scientists, he began attracting visiting researchers to the program from Japan as early as 1955. He traveled frequently to Japan, where he gave talks in classical Japanese. In 1975 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simple Aromatic Ring
Simple aromatic rings, also known as simple arenes or simple aromatics, are aromatic organic compounds that consist only of a conjugated planar ring system. Many simple aromatic rings have trivial names. They are usually found as substructures of more complex molecules (" substituted aromatics"). Typical simple aromatic compounds are benzene, indole, and pyridine. Simple aromatic rings can be heterocyclic if they contain non-carbon ring atoms, for example, oxygen, nitrogen, or sulfur. They can be monocyclic as in benzene, bicyclic as in naphthalene, or polycyclic as in anthracene. Simple monocyclic aromatic rings are usually five-membered rings like pyrrole or six-membered rings like pyridine. Fused/condensed aromatic rings consist of monocyclic rings that share their connecting bonds. Heterocyclic aromatic rings The nitrogen (N)-containing aromatic rings can be separated into basic aromatic rings that are easily protonated, and form aromatic cations and salts (e.g., pyridin ...

United States Public Health Service
The United States Public Health Service (USPHS or PHS) is a collection of agencies of the Department of Health and Human Services concerned with public health, containing nine out of the department's twelve operating divisions. The Assistant Secretary for Health oversees the PHS. The Public Health Service Commissioned Corps (PHSCC) is the federal uniformed service of the PHS, and is one of the eight uniformed services of the United States. PHS had its origins in the system of marine hospitals that originated in 1798. In 1871 these were consolidated into the Marine Hospital Service, and shortly afterwards the position of Surgeon General and the PHSCC were established. As the system's scope grew to include quarantine authority and research, it was renamed the Public Health Service in 1912. A series of reorganizations in 1966–1973 began a shift where PHS' divisions were promoted into departmental operating agencies. PHS was established as a thin layer of hierarchy above ...

Nobel Prize
The Nobel Prizes ( ; sv, Nobelpriset ; no, Nobelprisen ) are five separate prizes that, according to Alfred Nobel's will of 1895, are awarded to "those who, during the preceding year, have conferred the greatest benefit to humankind." Alfred Nobel was a Swedish chemist, engineer, and industrialist most famously known for the invention of dynamite. He died in 1896. In his will, he bequeathed all of his "remaining realisable assets" to be used to establish five prizes which became known as "Nobel Prizes." Nobel Prizes were first awarded in 1901. Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace (Nobel characterized the Peace Prize as "to the person who has done the most or best to advance fellowship among nations, the abolition or reduction of standing armies, and the establishment and promotion of peace congresses"). In 1968, Sveriges Riksbank (Sweden's central bank) funded the establishment of the Prize in Economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order Of The Sacred Treasure
The is a Japanese order, established on 4 January 1888 by Emperor Meiji as the Order of Meiji. Originally awarded in eight classes (from 8th to 1st, in ascending order of importance), since 2003 it has been awarded in six classes, the lowest two medals being abolished that year. Originally a male-only decoration, the order has been made available to women since 1919. The Order of the Sacred Treasure, which had 8 ranks until 2003, was awarded as a slightly lower rank than the Order of the Rising Sun for men and the Order of the Precious Crown for women. For example, the 1st class of the Order of the Sacred Treasure has been treated as between the 1st class and the 2nd class of the Order of the Rising Sun and the Order of the Precious Crown, and the 2nd class of the Order of the Sacred Treasure has been treated as between the 2nd class and the 3rd class of the Order of the Rising Sun and the Order of the Precious Crown.

Human Insulin
As a medication, insulin is any pharmaceutical preparation of the protein hormone insulin that is used to treat high blood glucose. Such conditions include type 1 diabetes, type 2 diabetes, gestational diabetes, and complications of diabetes such as diabetic ketoacidosis and hyperosmolar hyperglycemic states. Insulin is also used along with glucose to treat hyperkalemia (high blood potassium levels). Typically it is given by injection under the skin, but some forms may also be used by injection into a vein or muscle. There are various types of insulin, suitable for various time spans. The types are often all called ''insulin'' in the broad sense, although in a more precise sense, insulin is identical to the naturally occurring molecule whereas insulin analogues have slightly different molecules that allow for modified time of action. It is on the World Health Organization's List of Essential Medicines. In 2020, regular human insulin was the 307th most commonly prescribed medicat ...
