Physicochemical properties of enrofloxacin
Journal of Pharmaceutical and Biomedical Analysis, 1997The physicochemical properties of enrofloxacin, a fluoroquinolone that inhibits the activity of bacterial DNA gyrase, are described. Its spectral, solubility and related physicochemical characteristics are discussed. The dissociation behaviour of enrofloxacin was examined by UV spectrophotometry at 25 degrees C in a series of buffers ranging from pH 1 ...

Physicochemical environment of the colon
European Journal of Cancer Prevention, 1998Epidemiological evidence suggests that 80-90% of colorectal cancer is caused by dietary and environmental factors and that the prevalence of cancer can be altered in low-risk patients by long-term alterations in dietary fibre ingestion. It has therefore become increasingly important to examine the available data on colonic pH and transit, and on faecal

The physicochemical properties of digoxin
Journal of Pharmaceutical and Biomedical Analysis, 1985In a study of variations in the physicochemical properties of digoxin powder from several commercial sources, recrystallizations of digoxin were performed under several conditions. Polymorphs were not obtained whereas a pure amorphous form was formed under certain conditions.

On the Physicochemical Properties of Pyridohelicenes
Chemistry – A European Journal, 2013AbstractA comprehensive study on the physicochemical properties of a series of mono‐ and diaza[5]helicenes as well as mono‐ and diaza[6]helicenes is reported. Through the use of both computational and experimental methods, these helically chiral pyridohelicenes with the nitrogen atom(s) in various positions are characterised according to their ...

Physicochemical characterization of biopharmaceuticals
Journal of Pharmaceutical and Biomedical Analysis, 2016Biopharmaceuticals are gaining interest in therapy due to their high target selectivity. Most of the recently approved biopharmaceuticals represent drugs that are produced by biotechnological processes involving recombinant DNA. Thus, this review article mainly focusses on protein therapeutics.

Physicochemical Conditions in the Floodplains
1997The different water colors of Amazonian rivers are documented in the river names e.g., Rio Negro (black river), Rio Branco (white river), Rio Claro (clear river), Rio Verde (green river), and indicate differences in water quality. Sioli (1950) related water color to specific conditions in the catchment areas and recognized three main water types based ...

Physicochemical properties of bergenin
Die Pharmazie, 2008Physicochemical properties of bergenin, namely the solid state characteristics, solution stability, dissociation constant (pKa), solubility and octanol/water partition coefficient (Log P) were investigated. The results showed that the drug was not hygroscopic and was stable against heat and humidity in the solid state, but sensitive to hydrolysis in ...

Remote Homology Detection Using Physicochemical Parameters and Physicochemical Properties
2017 International Conference on Information Technology (ICIT), 2017Remote homology detection at amino acid level is a complex problem in bio-informatics. Similarity of sequences is very negligible and inconsequential when it is compared with their clan based resemblance. Thus customary detection methods may be replaced by modern Support Vector Machine (SVM) based approaches where a sequence is represented by ...

Bacterial adhesion: A physicochemical approach
Microbial Ecology, 1989The adhesion of bacteria to solid surfaces was studied using a physicochemical approach. Adhesion to negatively charged polystyrene was found to be reversible and could be described quantitatively using the DLVO theory for colloidal stability, i.e., in terms of Van der Waals and electrostatic interactions.
