Pharmacology
Pharmacology is a branch of medicine, biology and pharmaceutical sciences concerned with drug or medication action, where a drug may be defined as any artificial, natural, or endogenous (from within the body) molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism (sometimes the word ''pharmacon'' is used as a term to encompass these endogenous and exogenous bioactive species). More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties,functions,sources,synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. ...

Mathieu Jaboulay
Mathieu Jaboulay (5 July 1860 – 4 November 1913) was a French surgeon born in Saint-Genis-Laval, a city in the department of Rhône. He is remembered for introduction of new surgical procedures, as well as his work involving techniques of vascular anastomosis. He studied and practiced medicine in Lyon, where in 1902 he became a professor of clinical surgery. Two of his better known students at Lyon were Alexis Carrel (1873-1944) and René Leriche (1879-1955). In 1892 he introduced the side-to-side gastroduodenostomy, an operation used when the pylorus and proximal duodenum are badly scarred, and in 1894 he performed the first inter-ilio abdominal amputation or hemipelvectomy, a surgery involving amputation of the entire leg through the sacroiliac joint. This operation is sometimes referred to as "Jaboulay's amputation". He is credited with performing the first sympathectomic operation for alleviation of vascular disease. He described this surgery in a treatise titled ''Chiru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympathectomy
A sympathectomy is an irreversible procedure during which at least one sympathetic ganglion is removed. One example is the lumbar sympathectomy, which is advised for occlusive arterial disease in which L2 and L3 ganglia along with intervening sympathetic trunk are removed leaving behind the L1 ganglion which is responsible for ejaculation. Another example is endoscopic thoracic sympathectomy. Indications * * * Hyperhidrosis * Raynaud syndrome * * * Neuropathic Peripheral neuropathy, often shortened to neuropathy, is a general term describing disease affecting the peripheral nerves, meaning nerves beyond the brain and spinal cord. Damage to peripheral nerves may impair sensation, movement, gland, or o ... pain, although this is controversial * References {{surgery-stub Neurosurgical procedures ...

Serum (blood)
Serum () is the fluid and solute component of blood which does not play a role in Coagulation, clotting. It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors removed. Serum includes all proteins not used in Coagulation, blood clotting; all electrolytes, antibodies, antigens, hormones; and any exogenous substances (e.g., drugs or microorganisms). Serum does not contain white blood cells (leukocytes), red blood cells (erythrocytes), platelets, or clotting factors. The study of serum is serology. Serum is used in numerous diagnostic tests as well as blood typing. Measuring the concentration of various molecules can be useful for many applications, such as determining the therapeutic index of a drug candidate in a clinical trial. To obtain serum, a blood sample is allowed to clot (coagulation). The sample is then centrifuged to remove the clot and blood cells, and the resulting liquid wikt:supernatant, supernatant is serum. ...

Appendage
An appendage (or outgrowth) is an external body part, or natural prolongation, that protrudes from an organism's body. In arthropods, an appendage refers to any of the homologous body parts that may extend from a body segment, including antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, locomotor legs ( pereiopods for walking, and pleopods for swimming), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages. An appendage which is modified to assist in feeding is known as a maxilliped or gnathopod. In vertebrates, an appendage can refer to a locomotor part such as a tail, fins on a fish, limbs (legs, flippers or wings) on a tetrapod; exposed sex organ; defensive parts such as horns and antlers; or sensory organs such as auricles, proboscis ( trunk and snout) and barbels. Appendages may become ''uniramous'', as in insects and centipedes, where each appendage comprises a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vasomotor
Vasomotor refers to actions upon a blood vessel which alter its diameter. More specifically, it can refer to vasodilator action and vasoconstrictor action. Control Sympathetic innervation Sympathetic nerve fibers travel around the tunica media of the artery, secrete neurotransmitters such as norepinephrine into the extracellular fluid surrounding the smooth muscle (tunica media) from the terminal knob of the axon. The smooth muscle cell membranes have α and β-adrenergic receptors for these neurotransmitters. Activation of α-adrenergic receptors promotes vasoconstriction, while the activation of β-adrenergic receptors mediates the relaxation of muscle cells, resulting in vasodilation. Normally, α-adrenergic receptors predominates in smooth muscle of resistance vessels.Robert C. Ward et al. (2002). In Foundations for osteopathic medicine'.

Doctoral Thesis
A thesis ( : theses), or dissertation (abbreviated diss.), is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.International Standard ISO 7144: DocumentationPresentation of theses and similar documents International Organization for Standardization, Geneva, 1986. In some contexts, the word "thesis" or a cognate is used for part of a bachelor's or master's course, while "dissertation" is normally applied to a doctorate. This is the typical arrangement in American English. In other contexts, such as within most institutions of the United Kingdom and Republic of Ireland, the reverse is true. The term graduate thesis is sometimes used to refer to both master's theses and doctoral dissertations. The required complexity or quality of research of a thesis or dissertation can vary by country, university, or program, and the required minimum study period may thus vary significantly in du ...

Nicholas II Of Russia
Nicholas II or Nikolai II Alexandrovich Romanov; spelled in pre-revolutionary script. ( 186817 July 1918), known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer,. was the last Emperor of Russia, King of Congress Poland and Grand Duke of Finland, ruling from 1 November 1894 until his abdication on 15 March 1917. During his reign, Nicholas gave support to the economic and political reforms promoted by his prime ministers, Sergei Witte and Pyotr Stolypin. He advocated modernization based on foreign loans and close ties with France, but resisted giving the new parliament (the Duma) major roles. Ultimately, progress was undermined by Nicholas's commitment to autocratic rule, strong aristocratic opposition and defeats sustained by the Russian military in the Russo-Japanese War and World War I. By March 1917, public support for Nicholas had collapsed and he was forced to abdicate the throne, thereby ending the Romanov dynasty's 304-year rule of Russia (16 ...
