Nils Löfgren
Nils Löfgren (18 August 1913 – 21 January 1967) was a Swedish chemist who developed the anaesthetic Lidocaine (under the name Xylocaine) in 1943. At this time, he had recently finished his licentiate degree, and was teaching organic chemistry at the University of Stockholm. He and his co-worker Bengt Lundqvist sold the rights to Xylocaine to the Swedish pharmaceutical company Astra AB Astra AB was a former international pharmaceutical company headquartered in Södertälje, Sweden. Astra was formed in 1913 and merged with the British Zeneca, Zeneca Group in 1999 to form AstraZeneca. Product development was focused on therapeutics ....Early history of the Department of Analytical Chemistry at the University of Stockholm In 1948, Löfgren completed his doctorate, a ...

Chemist
A chemist (from Greek ''chÄ“m(Ãa)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. The work of chemists is often related to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anesthesia
Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness. An individual under the effects of anesthetic drugs is referred to as being anesthetized. Anesthesia enables the painless performance of procedures that would otherwise cause severe or intolerable pain in a non-anesthetized individual, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist: * General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation, using either injected or inhaled drugs. * Sedation suppresses the central nervous system to a lesser degree, inhibiting both anxiety and creation of long-term memories without resulting in unconsciousness. * Regional and local anesthesia, which blo ...

Lidocaine
Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anesthetic of the amino amide type. It is also used to treat ventricular tachycardia. When used for local anaesthesia or in nerve blocks, lidocaine typically begins working within several minutes and lasts for half an hour to three hours. Lidocaine mixtures may also be applied directly to the skin or mucous membranes to numb the area. It is often used mixed with a small amount of adrenaline (epinephrine) to prolong its local effects and to decrease bleeding. If injected intravenously, it may cause cerebral effects such as confusion, changes in vision, numbness, tingling, and vomiting. It can cause low blood pressure and an irregular heart rate. There are concerns that injecting it into a joint can cause problems with the cartilage. It appears to be generally safe for use in pregnancy. A lower dose may be required in those with liver problems. It is generally safe to use in those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Licentiate (degree)
A licentiate (abbreviated Lic.) is an academic degree present in many countries, representing different educational levels. It may be similar to a master's degree when issued by pontifical universities and other universities in Europe, Latin America, and Syria. The term is also used for a person who holds this degree. Etymology The term derives from Latin ''licentia'', "freedom" (from Latin ''licēre'', "to be allowed"), which is applied in the phrases ''licentia docendi'' (also ''licentia doctorandi''), meaning "permission to teach", and ''licentia ad practicandum'' (also ''licentia practicandi''), meaning "permission to practice", signifying someone who holds a certificate of competence to practise a profession. History The Gregorian Reform of the Catholic Church led to an increased focus on the liberal arts in episcopal schools during the 11th and 12th centuries, with Pope Gregory VII ordering all bishops to make provisions for the teaching of liberal arts.

Organic Chemistry
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.Clayden, J.; Greeves, N. and Warren, S. (2012) ''Organic Chemistry''. Oxford University Press. pp. 1–15. . Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical ( in silico) study. The range of chemicals studied in organic chemistry includes hydrocarbons (compounds containing only carbon and hydrogen) as well as compounds based on carbon, but also containing other elements, especially oxygen, nitrogen, sulfur, phosphorus (included in ...

Astra AB
Astra AB was a former international pharmaceutical company headquartered in Södertälje, Sweden. Astra was formed in 1913 and merged with the British Zeneca, Zeneca Group in 1999 to form AstraZeneca. Product development was focused on therapeutics for Gastroenterology, gastrointestinal, Cardiology, cardiovascular and Pulmonology, respiratory disorders and Anesthesia, pain control. At the time of the fusion, Astra was the largest Swedish pharmaceutical company. Astra also operated Astra Tech, a medical devices company, and marketed pharmaceuticals outside their primary development area, including Infectious disease, anti-infective agents. History The issue of domestic industrial production of pharmaceuticals in Sweden, as opposed to manual preparations by pharmacists, had been discussed among Swedish pharmacists since mid-1890s. At this time, German and Swiss pharmaceutical companies dominated the Swedish market. For a long time, this never led to more than discussions, but in 1913 ...
