Unconventional Platinum Anticancer Agents. Despite the clinical success that has been enjoyed by cisplatin, carboplatin, and oxaliplatin, treatment with these compounds inflicts a number of deleterious side-effects ().Among those affecting patient quality of life are nephrotoxicity, fatigue, emesis, alopecia, ototoxicity, peripheral neuropathy, and myelosupression (24, 25).
As with Group IV oils, Group V oils tend to offer performance advantages over Groups I – III. An example of a mineral-based Group V exception is a white oil, a very pure lubricant used in industries ranging from cosmetics to food processing. Are the API group classifications progressively better?

Every classification class has a unique identifier, a preferred name and a coded name that represents the classification structure (see below). With the development of [email protected] 7.1, the definition of a classification class was defined as a mandatory field, i.e. starting with [email protected] 7.1 every new classification class has to have a definition.
Platinum is both an essential and precious metal and is part of the six member family of platinum group metals (PGMs) which also includes palladium, rhodium, iridium, osmium, and ruthenium. These metals are known for their purity, high melting points and unique catalytic properties.
It is one of the of the six platinum group metals consisting of platinum, palladium, rhodium, osmium, iridium and ruthenium. It is highly reflective and extremely resistant to corrosion. It is not attacked by most acids. When present in compounds, rhodium exists mostly in the trivalent state, Rh 3+. Rhodium's salts form rose-colored aqueous ...
The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5, 6 and 7).
Platinum, in the form of the mineral sperrylite (PtAs 2), is also obtained as a byproduct of the nickel mining operation in the Sudbury region of Ontario, Canada. Credit for the modern rediscovery of platinum is usually given to Antonio de Ulloa. Platinum is a soft, dense, ductile metal that is very resistant to corrosion.

Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM). Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile.
Jan 19, 2019· A platinum plan is a standardized type of health insurance that pays, on average, roughly 90 percent of members' health care expenses. The members pay the other 10 percent of their health care expenses in the form of copayments, coinsurance, and deductibles.
Platinum jewelry is rare, beautiful, and durable, and is therefore highly regarded. Native Platinum is the most significant source of the element platinum, although considerable quantities are also mined from the rare platinum arsenide mineral Sperrylite. The rare metals iridium, osmium, rhodium, and palladium are almost exclusively mined ...
The Global Industry Classification Standard (GICS)SM was developed by and is the exclusive property and a service mark of MSCI and Standard & Poor's. Neither MSCI, Standard & Poor's nor any other party involved in making or
Platinum's properties allowed it to defy identification and classification until the 18 th century. Its high melting point and broad chemical resistance meant that obtaining a pure sample of the metal was difficult.

The PMC aims to prepare the technical dossiers for chemical substances on behalf of its member companies, as required by REACH. The International Platinum Group Metals Association (IPA) is a sister association of the EPMF from a cooperation point of view and as such, topics of relevance to the pgms are shared between the two associations.
Iridium and osmium were identified in the black residue remaining after dissolving platinum ore with aqua regia, a mixture of 25% nitric acid (HNO 3) and 75% hydrochloric acid (HCl). Today, iridium is still obtained from platinum ores and as a by-product of mining nickel. Pure iridium is very brittle and is nearly impossible to machine.
Cisplatin may be inadvisable if you have a history of severe allergic reaction to cisplatin, carboplatin, other platinum-containing formulations or mannitol. Do not receive any kind of immunization or vaccination without your doctor's approval while taking cisplatin.
Plans in the Health Insurance Marketplace are presented in 4 "metal" categories: Bronze, Silver, Gold, and Platinum. ("Catastrophic" plans are also available to some people.) FYI Metal categories are based on how you and your plan split the costs of your health care. They have nothing to do with quality of care.
The Goldschmidt classification, developed by Victor Goldschmidt, is a geochemical classification which groups the chemical elements according to their preferred host phases into lithophile (rock-loving), siderophile (iron-loving), chalcophile (ore-loving or chalcogen-loving), and atmophile (gas-loving) or volatile (the element, or a compound in which it occurs, is liquid or gaseous at ambient ...
A polyvalent hard white metal, ruthenium is a member of the platinum group. Like the other metals of the platinum group, ruthenium is inert to most chemicals. Most ruthenium is used for wear-resistant electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys. [Wikipedia].
The year 2007 marked the centenary of the death of Dmitri Mendeleev (1834–1907). This article discusses how he and some of his predecessors accommodated the platinum group metals (pgms) in the Periodic Table, and it considers the placing of their three transuranic congeners: hassium (108Hs), meitnerium (109Mt) and darmstadtium (110Ds). Over twenty-five years ago McDonald and Hunt (1) …
Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM). Osmium metal is lustrous, bluish white, extremely hard, and brittle even at high temperatures. It has the highest melting point and lowest vapour pressure of the platinum group.

Platinum-based antineoplastic agents are sometimes described as "alkylating-like" due to similar effects as alkylating antineoplastic agents, although they do not have an alkyl group. Examples. Strategies for improving platinum-based anticancer drugs usually involve changes in the neutral spectator ligands, which are usually nitrogenous ...
