surfactant molecules are used as interesting tools to study the structure, function and stability of proteins. protonation states of amino acids may be changed in the presence of surfactants. in this work, using experimental observations and molecular dynamic simulation, the effects of sodium dodecyl sulfate on the acid dissociation constants of tryptophan was examined. the acid–base equilibriu...

background: aspirin is the most widely used drug in medicine for cardiovascular and as recently for its role in cancer prevention. although the risk of bleeding events increased following regular use of aspirin, little is known about the association of aspirin and hematuria. the present study aimed to evaluate the association of regular aspirin use and microscopic hematuria in elderly. methods:...

Background This study aimed to describe the epidemiologic characteristics of

We study a genuine Brownian motor by hard disk molecular dynamics and calculate analytically its properties, including its drift speed and thermal conductivity, from microscopic theory.

Microplasma welding is a less expensive alternative to laser welding in dental technology. The aim of the study was to highlight discontinuities present in the microplasma welded joints of dental base metal alloys by visual analysis. Five base metal alloys designated for fixed prostheses manufacture were selected for the experiments. Using these plates, preliminary tests were conducted by micro...
