Carl Peter Henrik Dam
Carl Peter Henrik Dam ( da, Carl Peter Henrik Dam), (21 February 1895 – 17 April 1976) was a Danish biochemist and physiologist. He was awarded the Nobel Prize in Medicine in 1943 for joint work with Edward Doisy in discovering vitamin K and its role in human physiology. Dam's key experiment involved feeding a cholesterol-free diet to chickens. He initially replicated experiments reported by scientists at the Ontario Agricultural College (OAC). McFarlane, Graham and Richardson, working on the chick feed program at OAC, had used chloroform to remove all fat from chick chow. They noticed that chicks fed only fat-depleted chow developed hemorrhages and started bleeding from tag sites. Dam found that these defects could not be restored by adding purified cholesterol to the diet. It appeared that—together with the cholesterol—a second compound had been extracted from the food, and this compound was called the coagulation vitamin. The new vitamin received the letter K because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nobel Prize In Medicine
The Nobel Prize in Physiology or Medicine is awarded yearly by the Nobel Assembly at the Karolinska Institute for outstanding discoveries in physiology or medicine. The Nobel Prize is not a single prize, but five separate prizes that, according to Alfred Nobel's 1895 will, are awarded "to those who, during the preceding year, have conferred the greatest benefit to humankind". Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace. The Nobel Prize is presented annually on the anniversary of Alfred Nobel's death, 10 December. As of 2022, 114 Nobel Prizes in Physiology or Medicine have been awarded to 226 laureates, 214 men and 12 women. The first one was awarded in 1901 to the German physiologist, Emil von Behring, for his work on serum therapy and the development of a vaccine against diphtheria. The first woman to receive the Nobel Prize in Physiology or Medicine, Gerty Cori, received it in 1947 for her role in elucidating the ...

Cholesterol
Cholesterol is any of a class of certain organic molecules called lipids. It is a sterol (or modified steroid), a type of lipid. Cholesterol is biosynthesized by all animal cells and is an essential structural component of animal cell membranes. When chemically isolated, it is a yellowish crystalline solid. Cholesterol also serves as a precursor for the biosynthesis of steroid hormones, bile acid and vitamin D. Cholesterol is the principal sterol synthesized by all animals. In vertebrates, hepatic cells typically produce the greatest amounts. It is absent among prokaryotes (bacteria and archaea), although there are some exceptions, such as '' Mycoplasma'', which require cholesterol for growth. François Poulletier de la Salle first identified cholesterol in solid form in gallstones in 1769. However, it was not until 1815 that chemist Michel Eugène Chevreul named the compound "cholesterine". Etymology The word "cholesterol" comes from the Ancient Greek ''chole-'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Copenhagen
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Lindau Nobel Laureate Meetings
The Lindau Nobel Laureate Meetings are annual scientific conferences held in Lindau, Bavaria, Germany, since 1951. Their aim is to bring together Nobel laureates and young scientists to foster scientific exchange between different generations, cultures and disciplines. The meetings assume a unique position amongst international scientific conferences, as from 30 to 65 Nobel laureates attending each edition they are the largest regular congregation of Nobel laureates in the world, apart from the Nobel Prize award ceremony in Stockholm. Purpose Every Lindau Meeting consists of a multitude of scientific sessions like plenary lectures and panel discussions as well as a variety of networking and social events. The meetings are not centered on the presentation of research results, but instead, their main goals are the exchange of ideas and the discussion of topics globally relevant to all scientists. The Nobel laureates do not receive any kind of payment for their participation and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microchemistry
Microscale chemistry (often referred to as small-scale chemistry, in German: Chemie im Mikromaßstab) is an analytical method and also a teaching method widely used at school and at university levels, working with small quantities of chemical substances. While much of traditional chemistry teaching centers on multi-gramme preparations, milligrammes of substances are sufficient for microscale chemistry. In universities, modern and expensive lab glassware is used and modern methods for detection and characterization of the produced substances are very common. In schools and in many countries of the Southern hemisphere, small-scale working takes place with low-cost and even no-cost material. There has always been a place for small-scale working in qualitative analysis, but the new developments can encompass much of chemistry a student is likely to meet. History There are two main strands of the modern approach. One is based on the idea that many of the experiments associated with ...
