Argyria
Argyria or argyrosis is a condition caused by excessive exposure to chemical compounds of the element silver, or silver dust. The most dramatic symptom of argyria is that the skin turns blue or blue-gray, and is usually most prominent in sun-exposed areas of the skin. It may take the form of ''generalized argyria'' or ''local argyria''. Generalized argyria affects large areas over much of the visible surface of the body. Local argyria shows in limited regions of the body, such as patches of skin, parts of the mucous membrane, or the conjunctiva. The terms ''argyria'' and ''argyrosis'' have long been used interchangeably, with ''argyria'' being used more frequently. ''Argyrosis'' has been used particularly in referring to argyria of the conjunctiva, but the usage has never been consistent and cannot be relied on except where it has been explicitly specified. The term is from the (, 'silver'). Pathophysiology In humans and other animals, chronic intake of silver products common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colloidal Silver
The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. The limited evidence available shows that silver coatings on endotracheal breathing tubes may reduce the incidence of ventilator-associated pneumonia. There is tentative evidence that using silver-alloy indwelling catheters for short-term catheterizing will reduce the risk of catheter-acquired urinary tract infections. Silver generally has low toxicity, and minimal risk is expected when silver is used in approved medical applications. Alternative medicine products such as colloidal silver are controversial. Mechanism of action Silver and most silver compounds have an oligodynamic effect and are toxic for bacteria, algae, and fungi ''in vitro''. The antibacterial action of silver is dependent on the silver ion. The effectiveness of silver compoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stan Jones (Libertarian Politician)
Stan Jones (born January 13, 1943) is an American Libertarian Party politician who has twice run unsuccessfully for the United States Senate, in 2002 and 2006, and three times unsuccessfully as the Libertarian nominee for governor of Montana, in 2000, 2004, and 2008. He is known for his artificially induced blue-grey skin tone, caused by argyria. Medical condition In his book '' The Disappearing Spoon'', about the periodic table, author Sam Kean chronicled the experience of Jones, who developed argyria, which permanently turned his skin a blue-grey color, by consuming large quantities of home-made colloidal silver. Jones' purposeful consumption of silver, which he believed to be an antibiotic, was a measure he undertook in response to his fears that the Y2K problem would make antibiotics unavailable, an event that did not occur. The peculiar coloration of his skin featured prominently in media coverage of his unsuccessful campaign. Jones is reported to have said, given the ...

Silver
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-gray
Livid is a medium bluish- gray color. This color name comes from the Latin color term ''lividus'', meaning "'a dull leaden-blue color'; it is also used to describe the color of contused flesh, leading to the English expression 'black and blue'". The first recorded use of ''livid'' as a color name in English was in 1622. There is a range of colors called ''livid'' colors that combine the colors blue and gray. Some of these colors are shown below. Livid (blue-gray) is the opposite concept from brown. Brown colors are mainly ''dark orange'' and ''dark red'' colors—warm colors on the warm color side of the color wheel, while blue-gray (livid) colors are mainly ''dark blue'' and ''dark azure'' colors—colors on the opposite side of the color wheel—cool colors on the cool color side of the color wheel. Alternate names are blue-gray (American English) or blue-grey (British English), which was a name introduced by Crayola for a crayon color used from 1958 to 1990. Thus, the ...

Dermatology
Dermatology is the branch of medicine dealing with the Human skin, skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A List of dermatologists, dermatologist is a specialist medical doctor who manages diseases related to skin. Etymology Attested in English in 1819, the word "dermatology" derives from the Ancient Greek, Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία ''wikt:-logia, -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases (Jean-Louis-Marc Alibert, Alibert's, 1806–1816) appeared in print around the same time.Freedber ...

Colloid
A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid, while others extend the definition to include substances like aerosols and gels. The term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word '' suspension'' is distinguished from colloids by larger particle size). A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). The dispersed phase particles have a diameter of approximately 1 nanometre to 1 micrometre. Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color. Colloidal suspensions are the subject of interface and colloid science. This field of study began in 1845 by Franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ionic Liquid
An ionic liquid (IL) is a salt (chemistry), salt in the liquid state at ambient conditions. In some contexts, the term has been restricted to salts whose melting point is below a specific temperature, such as . While ordinary liquids such as water and gasoline are predominantly made of electric charge, electrically neutral molecules, ionic liquids are largely made of ions. These substances are variously called liquid electrolytes, ionic melts, ionic fluids, fused salts, liquid salts, or ionic glasses. Ionic liquids have many potential applications. They are powerful solvents and can be used as electrolytes. Salts that are liquid at near-ambient temperature are important for electric battery applications, and have been considered as sealants due to their very low vapor pressure. Any salt that melts without pyrolysis, decomposing or vaporizing usually yields an ionic liquid. Sodium chloride (NaCl), for example, melts at into a liquid that consists largely of sodium cations () and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penicillin
Penicillins (P, PCN or PEN) are a group of beta-lactam antibiotic, β-lactam antibiotics originally obtained from ''Penicillium'' Mold (fungus), moulds, principally ''Penicillium chrysogenum, P. chrysogenum'' and ''Penicillium rubens, P. rubens''. Most penicillins in clinical use are synthesised by ''Penicillium chrysogenum, P. chrysogenum'' using industrial fermentation, deep tank fermentation and then purified. A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: benzylpenicillin, penicillin G (intramuscular injection, intramuscular or Intravenous therapy, intravenous use) and phenoxymethylpenicillin, penicillin V (given by mouth). Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococcus, staphylococci and streptococcus, streptococci. They are still widely used today for various bacterial infections, though many types of bacteria have developed antibiotic res ...

Libertarian Party (United States)
The Libertarian Party (LP) is a Political parties in the United States, political party in the United States. It promotes civil liberties, non-interventionism, Laissez-faire capitalism, ''laissez-faire'' capitalism, and Limited government, limiting the size and scope of government. The world's first explicitly libertarian party, it was conceived in August 1971 at meetings in the home of David Nolan (libertarian), David F. Nolan in Westminster, Colorado, and was officially formed on December 11, 1971, in Colorado Springs, Colorado, Colorado Springs. The organizers of the party drew inspiration from the works and ideas of the prominent Austrian school economist Murray Rothbard. The founding of the party was prompted in part due to concerns about the Presidency of Richard Nixon, Nixon administration's wage and price controls, the Vietnam War, Conscription in the United States#Vietnam War, conscription, and the introduction of fiat money.

Suspension (chemistry)
In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out. Properties A suspension is a heterogeneous mixture in which the solid particles do not dissolve, but get suspended throughout the bulk of the solvent, left floating around freely in the medium. The internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation, with the use of certain excipients or suspending agents. An example of a suspension would be sand in water. The suspended particles are visible under a microscope and will settle over time if left undisturbed. This distinguishes a suspension from a colloid, in which the colloid particles are smaller and do not settle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
