High Quality Content by WIKIPEDIA articles! Seratrodast (INN) is a thromboxane A2 (TXA2) receptor (TP receptor) antagonist used primarily in the treatment of asthma. It was the first TP receptor antagonist that was developed as an anti-asthmatic drug and received marketing approval in Japan in 1997. Seratrodast is currently marketed in Japan, China and India (approved in Dec 2012) as an add-on controller therapy in the management of asthma.
High Quality Content by WIKIPEDIA articles! Serine (abbreviated as Ser or S) is an amino acid with the formula HO2CCH(NH2)CH2OH. It is one of the proteinogenic amino acids. By virtue of the hydroxyl group, serine is classified as a polar amino acid.
High Quality Content by WIKIPEDIA articles! Sevoflurane (1,1,1,3,3,3-hexafluoro-2-(fluoromethoxy)propane), also called fluoromethyl hexafluoroisopropyl ether, is a sweet-smelling, nonflammable, highly fluorinated methyl isopropyl ether used for induction and maintenance of general anesthesia. Together with desflurane, it is replacing isoflurane and halothane in modern anesthesiology. It is often administered in a mixture of nitrous oxide and oxygen. After desflurane, it is the most volatile anesthetic with the fastest onset and offset. Though desflurane has the lowest blood/gas coefficient of the currently used volatile anesthetics, sevoflurane is the preferred agent for mask induction due to its lesser irritation to mucous membranes.
High Quality Content by WIKIPEDIA articles! Sheffield plate is a layered combination of silver and copper that was used for many years to produce a wide range of household articles. These included buttons, caddy spoons, serving utensils, candlesticks and other lighting devices, tea and coffee services, serving dishes and trays, tankards and pitchers, and larger items such as soup tureens and hot-water urns. Almost every article made in sterling silver was also crafted by Sheffield makers, who used this manufacturing process to produce nearly identical wares at far less cost.

Until 2010 it was marketed and prescribed as an adjunct in the treatment of exogenous obesity along with diet and exercise. It has been associated with increased cardiovascular events and strokes and has been withdrawn from the market in countries and regions including Australia,Canada,China, the European Union (EU),Hong Kong,India, Mexico, New Zealand,Thailand, the United Kingdom, and the United States.

High Quality Content by WIKIPEDIA articles! Silanes are chemical compounds of silicon and hydrogen, which are analogues of alkane hydrocarbons. Silanes consist of a chain of silicon atoms covalently bonded to each other and to hydrogen atoms. The general formula of a silane is SinH2n+2. Much of the early work establishing that silicon does indeed form an homologous series of hydrides analogous to the alkanes, albeit to a much smaller extent, was conducted by Alfred Stock and Carl Somiesky. Although monosilane and disilane were already known, Stock and Somiesky discovered, beginning in 1916, the next four members of the SinH2n+2 series, up to n = 6, and they also documented the formation of solid phase polymeric silicon hydrides (vide...
High Quality Content by WIKIPEDIA articles! Silicon, a tetravalent metalloid, is a chemical element with the symbol Si and atomic number 14. It is less reactive than its chemical analog carbon, the nonmetal directly above it in the periodic table, but more reactive than germanium, the metalloid directly below it in the table. Controversy about silicon`s character dates to its discovery: silicon was first prepared and characterized in pure form in 1823. In 1808, it was given the name silicium (from Latin: silicis, flints), with an -ium word-ending to suggest a metal, a name which the element retains in several non-English languages. However, its final English name, first suggested in 1817, reflects the more physically similar elements...
High Quality Content by WIKIPEDIA articles! A silsesquioxane is a compound with the empirical chemical formula RSiO3/2 where Si is the element silicon, O is oxygen and R is either hydrogen or an alkyl, alkene, aryl, arylene group. These materials can be used as a support for catalysts, and recently on pH-responsive material. Silsesquioxanes can have a cage like structure, see Figure 1, which is most commonly cubes, hexagonal prisms, octagonal prisms, decagonal and dodecagonal prisms.<

High Quality Content by WIKIPEDIA articles! Silver, like other precious metals, may be used as an investment. For more than four thousand years, silver has been regarded as a form of money and store of value. However, since the end of the silver standard, silver has lost its role as a popular legal tender in many developed countries such as the United States. In 2009, the main demand for silver was for industrial applications (40%), jewellery, bullion coins and exchange-traded products. In 2011, the global silver reserves amounted to 530,000 tonnes.
High Quality Content by WIKIPEDIA articles! Silver mining in Arizona was a powerful stimulus for exploration and prospecting in early Arizona. Cumulative silver production through 1981 totaled 490 million troy ounces (15 million kg). However, only about 10% of Arizona`s silver production came from silver mining. More than 80% of the state`s silver was a byproduct of copper mining; other silver came as a byproduct of lead, zinc, and gold mining.
High Quality Content by WIKIPEDIA articles! Silver Certificates are a type of representative money printed from 1878 to 1964 in the United States as part of its circulation of paper currency. They were produced in response to silver agitation by citizens who were angered by the Fourth Coinage Act, which had effectively placed the United States on a gold standard. The certificates were initially redeemable in the same face value of silver dollar coins, and later in raw silver bullion. Since 1968 they have been redeemable only in Federal Reserve Notes and are thus obsolete, but are still valid legal tender.
High Quality Content by WIKIPEDIA articles! Sitagliptin (INN; previously identified as MK-0431 and marketed as sitagliptin phosphate under the trade name Januvia) is an oral antihyperglycemic (antidiabetic drug) of the dipeptidyl peptidase-4 (DPP-4) inhibitor class. It was developed, and is marketed, by Merck Co. This enzyme-inhibiting drug is used either alone or in combination with other oral antihyperglycemic agents (such as metformin or a thiazolidinedione) for treatment of diabetes mellitus type 2. The benefit of this medicine is its fewer side effects (e.g., less hypoglycemia, less weight gain) in the control of blood glucose values. While safety is its advantage, efficacy is often challenged as it is often recommended to be...
