Recent analysis: Distance-of-flight mass spectrometry (DOFMS), and several offshoots work in petroleomics, lipidomics, proteomics, and metabolomics have provided data from that study. Basically, DOFMS is very similar to time-of-flight mass spectrometry that substantiate this observation. This observed regularity provides the basis for (TOFMS), but tailored for folks who are impatient.

Despite the significant progress in this area, the effect of commonly employed pharmaceutical excipients, such as surfactants, on the solubility of drugs in BDM has not been characterized in detail. The aim of this study is to clarify the impact of surfactant−bile interactions on drug solubility by using a set of 12 surfactants, 3 model hydrophobic drugs (fenofibrate, danazol, and progesterone) and two types of BDM (porcine bile extract and sodium taurodeoxycholate). Drug precipitation and sharp nonlinear decrease in the solubility of all studied drugs is observed when drug-loaded ionic surfactant micelles are introduced in solutions of both BDM, whereas the drugs remain solubilized in the mixtures of nonionic polysorbate surfactants + BDM. One-dimensional and diffusion-ordered 1H NMR spectroscopy show that mixed bile salt + surfactant micelles with low drug solubilization capacity are formed for the ionic surfactants. On the other hand, separate surfactant-rich and bile salt-rich micelles coexist in the nonionic polysorbate surfactant + bile salt mixtures, explaining the better drug solubility in these systems.

    Cognitive Enhancing Agents: Current Status in the Treatment of Alzheimer's Disease

    LE JOURNAL CANADIEN DES SCIENCES NEUROLOGIQUES REVIEW ARTICLE Cognitive Enhancing Agents: Current Status in the Treatment of Alzheimer's Disease Cheryl Waters ABSTRACT: Extensive recent literature on drugs used to enhance cognitive functioning, reflects the growing social problem of dementia. Many clinical trials have been undertaken with variable success. In most cases the disorder stud­ ied has been Alzheimer's disease. The pharmacological approach has been designed to rectify the presumed patho­ physiological processes characteristic of the condition. Agents tested include cerebral vasodilators, cerebral metabolic enhancers, nootropics, psychostimulants, neuropeptides and neurotransmitters with a special emphasis on drugs used to enhance cholinergic function. Ethical and practical issues concerning clinical drug trials in dementia will be discussed.

As a result of their wide spread use, the biodegradation characteristics of LAS have been studied thoroughly under both laboratory and environmental conditions. Laboratory tests typically show that LAS will undergo rapid primary and ultimate biodegradation. Due to its favorable biodegradation characteristics, LAS is presently listed as a recommended control substance in the OECD "Readily Biodegradability: Closed Bottle Test". OECD Modified Sturm testing of a LAS product, BIO-SOFT® S-100, showed this product to be readily biodegradable. Primary biodegradation, which can reach 100% in 3 days, involves oxidation of the carbon atoms at the alkyl side chain to form transient, low toxicity sulfophenyl carboxylate intermediates. This is followed by complete breakdown characterized by cleavage of the aromatic ring and total mineralization to carbon dioxide, water and inorganic sulfonates.
