Nilavarai Curnam, a compound drug formulation in Siddha System of Medicine was analysed. The Microscopic methods of identifying their ingredients, Chemical analysis, Fluorescence, and Thin Layer Chromatographic studies of the drug have been reported here.

Nationally distributed medications from compounding pharmacies, which typically adhere to less stringent quality-control standards than pharmaceutical manufacturers, can lead to multistate outbreaks. We investigated a cluster of 6 patients in a Maryland hospital who had Sphingomonas paucimobilis bloodstream infections in November 2007. Of the 6 case-patients, 5 (83%) had received intravenous fe...

Natural rubber is produced by a rubber transferase (a cis-prenyltransferase). Rubber transferase uses allylic pyrophosphate to initiate the rubber molecule and isopentenyl pyrophosphate (IPP) to form the polymer. Rubber biosynthesis also requires a divalent metal cation. Understanding how molecular weight is regulated is important because high molecular weight is required for high quality rubbe...

The experience of art emerges from the interaction of various cognitive and affective processes. The unfolding of these processes in time and their relation with viewing behavior, however, is still poorly understood. Here we examined the effect of context on the relation between the experience of art and viewing time, the most basic indicator of viewing behavior. Two groups of participants view...

Investigating the methods commonly used to evaluate in vitro cytotoxicity of novel compounds, specifically non-covalent DNA binders, identifies that these methods may not be appropriate. The level of anticancer activity depends not only on the incubation time but also on the absolute amount (number of moles) of drug compound applied, rather than the concentration.

Optimal learning addresses the problem of efficiently collecting information with which to make decisions. These problems arise in both offline settings (making a series of measurements, after which a decision is made) and online settings (the process of making a decision results in observations that change the distribution of belief about future observations). Optimal learning is an issue prim...

The potential for contamination of compounded products and the resulting infections are a serious threat to patient safety. Immediate use products are used frequently in the perioperative department, and perioperative nurses should be familiar with the guidelines and practices that aim to reduce the contamination that can occur during the sterile compounding process. Four common themes lead to ...

Rubber biosynthesis takes place on the surface of rubber particles. These particles are surrounded by a monolayer membrane in which the rubber transferase is anchored. In order to gain better insight into whether rubber particles from different plant species share common structural characteristics, the micromorphology of rubber particles from Ficus carica, Ficus benghalensis, and Hevea brasilie...
