Secondary Thrombocytosis
Etiology. The common factor among the various underlying causes of secondary thrombocytosis is the presence of inflammatory compounds, such as interleukin 6 (IL6), which enhance thrombopoietin secretion and subsequently increase megakaryocyte production. Secondary thrombocytosis etiologies are often categorized under the "5 …

The steel making process involves several key stages: preparation of raw materials such as iron ore, coke, and limestone; smelting and reduction to produce molten iron; primary steelmaking which converts molten iron to steel using methods like the Basic Oxygen Furnace (BOF) or Electric Arc Furnace (EAF); casting where steel is formed into …
24.1: Werner's Theory of Coordination Compounds
These data led Werner to postulate that metal ions have two different kinds of valence: (1) a primary valence (oxidation state) that corresponds to the positive charge on the metal ion and (2) a secondary valence (coordination number) that is the total number of ligand-metal bonds bound to the metal ion. If (ce{Pt}) had a primary valence of ...

Secondary Iron Overload and the Liver: A Comprehensive …
Iron overload can be categorized into primary and secondary causes. Primary iron overload, so-called hereditary hemochromatosis, is a well-recognized …
Iron Overload
Iron overload occurs when there are excess stores of iron in the body. Primary iron overload is often inherited. Secondary iron overload usually arises from causes such as transfusion, hemolysis, or excessive parenteral and/or dietary consumption of iron. Excess iron is deposited into organs throughout the body, which can damage …
HFE gene in primary and secondary hepatic iron overload
NOMENCLATURE OF IRON OVERLOAD. Hereditary, or primary, haemochromatosis is an inherited iron storage disease. Secondary iron overload is acquired as a result of another disease. The nomenclature and classification of iron overload states is shown in Table Table1. 1.

Primary and secondary sulfonamides are both competent coupling partners, with yields from 55% to 88% for deoxybenzoin-derived substrates. ... Iron catalysis is an exciting approach to α-functionalization with multiple mechanistic possibilities. Three prior examples of iron-catalyzed oxidative coupling reactions are shown in Scheme 1. These ...
Steel 101: Understanding Primary and Secondary Steel
Primary steel is costlier compared to the two, due to the use of iron ore directly. Therefore the percentage of quality steel produced is more in primary compared to secondary. Product quality and cost of production is also much higher in primary steel. Conclusion – TMT bars. Both primary and secondary TMT bars contain a low percentage of ...
