The name originally applied to all synthetic rubbers produced by the sodium polymerisation of butadiene it is derived from Bu for butadiene and Na for sodium. The name was subsequently used in various forms, e.g., Buna N for nitrile rubber or NBR, and Buna S for SBR. The tradename Perbunan (Bayer) is also derived from Buna. 

This is the preferred designation for all chloroprene polymers and copolymers. Chloroprene rubber was first introduced commercially in 1931 by DuPont and their trade name, originally DuPrene, later Neoprene, has almost become a generic term for all such rubber. See Chlorobutadiene. 

A paste of polyvinyl chloride and plasticiser. The name originated in the USA and is now in general use. 

Rab is a family of small G proteins involved in membrane vesicle trafficking. Mammalian tissues contain around 30 forms of Rab, which specifically associate with the various types of membrane vesicles and organelles that exist in cells [30,31]. Rab proteins, named originally as ras-related proteins in brain, are isoprenylated and associate with membranes, as do isoprenylated Ras and G protein y subunits. However, unlike these other G proteins, the GTP and GDP binding to Rab appears to regulate its association with membrane compartments. 

A second family of MAPKs is referred to as stress-activated protein kinases (SAPKs) [3,14,15]. This includes JNKs, or Jun kinases, named originally for their phosphorylation of the transcription factor c-Jun. SAPKs were first identified in peripheral tissues on the basis of their activation in response to cellular forms of stress, which include X-ray irradiation and osmotic stress. More recently, they have been demonstrated to be activated in brain by several cytokines as well as by synaptic activity [16]. As shown in Figure 23-3, SAPKs are activated by SAPK kinases (SEKs), which are in turn activated by SEK kinases. The Ras-like small G proteins implicated in SEK kinase activation are Rac and Cdc-42. In this case, it appears that Rac/Cdc-42 triggers activation of SEK kinase by stimulating its phosphorylation by still another protein kinase termed p21-activated kinase (PAK). Thus, PAK can be considered a MAPK kinase kinase kinase, which is analogous to the cascade of protein kinases found in yeast (Fig. 23-4). 

The electrified interface is generally referred to as the electric double layer (EDL). This name originates from the simple parallel plate capacitor model of the interface attributed to Helmholtz.1,9 In this model, the charge on the surface of the electrode is balanced by a plane of charge (in the form of nonspecifically adsorbed ions) equal in magnitude, but opposite in sign, in the solution. These ions have only a coulombic interaction with the electrode surface, and the plane they form is called the outer Helmholtz plane (OHP). Helmholtz s model assumes a linear variation of potential from the electrode to the OHP. The bulk solution begins immediately beyond the OHP and is constant in potential (see Fig. 1). 

ORIGIN OF NAME The name originates from the Greek word iodes, meaning "violet-colored," which is the color of iodine s vapor. 

ORIGIN OF NAME Originally named "niton" after the Latin word for "shining," it was given the name "radon" in 1923 because it is the radioactive decay gas of the element radium.

Aromatic The name originally given to cyclical compounds containing the benzene "ring" because the first benzene-type compounds isolated smelled "good". 

Common Name The name originally given to a compound upon its discovery, prior to the adoption of an organized system of assigning proper names. 

Natamycin is another polyene antibiotic effective against dermatophytes. The name originally proposed for the compound was pimaricin, which has been used in some of the earlier literature studies and reports. It has been used as topical therapeutic in animals and humans for over 30 years, and it is also used as an antifungal agent in food processing. 

In the theory of diffusion-controlled reactions it is called the radiative boundary condition . This quaint name originated from H.S. Carslaw and J.C. Jaeger, Conduction of Heat in Solids (Clarendon Press, Oxford 1947) p. 13. 

All of the known simple plant isoquinolines have been entered into this index under their common, or trivial names. Originally, there was a linear structure code attached to the trivial name entry which allowed the reader to immediately deduce the chemical structure and to access the compound directly in the structural index. It became apparent that a single page reference would do as well. Each trivial name thus leads to the chemical structure, the plants that contain that compound, and appropriate literature references.
