Paul Héger
Paul Héger (born Paul Marie François Xavier Héger; 13 December 1846 – 8 November 1925) was a Belgian scientist. He was famous for his collaboration with the chemist Ernest Solvay to discover the Solvay Process. Alongside Solvay, he donated a large sum of money to fund Leopold Park and helped establish the Solvay Institute of Physiology and Institute of Sociology. Additionally, he made substantial contributions to the understanding of blood circulation, especially in the context of artificial circulation, demonstrating that the vascular endothelium actively participates in circulation and osmosis, challenging the view of blood vessels as passive conduits. He also discovered that adding nicotine to circulating blood increases blood flow speed through living tissues. Heger also made contributions to the understanding of liver function. He found that the liver significantly reduces alkaloid concentration in blood, highlighting its role in detoxification. Additionally, he sho ...

Vienna General Hospital
The Vienna General Hospital (), usually abbreviated to AKH, is the general hospital in Vienna, Austria. It is also the city's university hospital, and the site of the Medical University of Vienna. It is Europe's fifth largest hospital, both by number of employees and bed capacity. History Old AKH The origins of Vienna General Hospital go back to Dr. Johann Franckh, who donated properties in 1686, after the end of the second Siege of Vienna, at the corridor Schaffernack for the establishment of a military hospital. However, since money was lacking for the establishment of the buildings, the disabled veterans were quartered, including families, in the Kontumazhof (epidemic hospital), already in existence. In 1693, Emperor Leopold I arranged the establishment of the large hospital. In 1697, the first ward was finished, into which 1,042 persons were quartered. By 1724, 1,740 persons lived there. Extension of the complex was made possible by the will of Ferdinand Baron v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Detoxification
Detoxification or detoxication (detox for short) is the physiological or medicinal removal of toxic substances from a living organism, including the human body, which is mainly carried out by the liver. Additionally, it can refer to the period of drug withdrawal during which an organism returns to homeostasis after long-term use of an addictive substance. In medicine, detoxification can be achieved by Poison#Decontamination, decontamination of poison ingestion and the use of antidotes as well as techniques such as Kidney dialysis, dialysis and (in a limited number of cases) chelation therapy. Many alternative medicine practitioners promote various types of detoxification such as Detoxification (alternative medicine), detoxification diets. Sense about Science, a UK-based charitable trust, determined that most such dietary "detox" claims lack any supporting evidence. The liver and kidney are naturally capable of detox, as are intracellular (specifically, inner membrane of mitochon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alkaloid
Alkaloids are a broad class of natural product, naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large variety of organisms including bacteria, fungus, fungi, Medicinal plant, plants, and animals. They can be purified from crude extracts of these organisms by acid-base extraction, or solvent extractions followed by silica-gel column chromatography. Alkaloids have a wide range of pharmacology, pharmacological activities including antimalarial medication, antimalarial (e.g. quinine), asthma, antiasthma (e.g. ephedrine), chemotherapy, anticancer (e.g. omacetaxine mepesuccinate, homoharringtonine), cholinomimetic (e.g. galantamine), vasodilation, vasodilatory (e.g. vincamine), Antiarrhythmic agent, antiarrhythmic (e.g. quinidine), analgesic (e.g. morphine), antibacterial (e.g. chelerythrine), and anti-diabetic, antihyperglycemic activities (e.g. berb ...

Nicotine
Nicotine is a natural product, naturally produced alkaloid in the nightshade family of plants (most predominantly in tobacco and ''Duboisia hopwoodii'') and is widely used recreational drug use, recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve drug withdrawal, withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist. Nicotine constitutes approximately 0.6–3.0% of the dry weight of tobacco. Nicotine is also present at Parts-per notation, ppb concentrations in edible plants in the family Solanaceae, including potatoes, tomatoes, and eggplants, though sources disagree on whether this has any biological significance to human consumers. It functions as an plant defense against herbivory, antiherbivore toxin; consequently, nicotine was widely used as an insecti ...
