By the early 1990s, the PCR technique with Taq polymerase was being used in many areas, including basic molecular biology research, clinical testing, and forensics. It also began to find a pressing application in direct detection of the HIV in AIDS.
Abstract. The solubility of fructose in waterâethanol and waterâmethanol mixtures and the saturated density of each solution at 20, 30, and 40 Â°C over a range of water mass percentage have been measured.Also, a new modification of the Wilson model has been proposed to describe solubility data satisfactorily.bstract.

Greater the lipid water solubility coefficient, more is the lipid solubility of the drug and greater is the absorption. Less the coefficient, less is the lipid solubility and less is the absorption. Water film exists on the membranes so part of the drugs must be water soluble to cross this water film.Drugs with benzene ring, hydrocarbon chain, steroid nucleus and halogen groups in their structures are lipid soluble.rea of Absorptive Surface. Area of absorptive surface affects oral as well as other routes. Most of the drugs are given orally because of the large area of absorptive surface, so that greater absorption occurs. Intestinal resection decreases the surface area leading to a decreased absorption.
