background: there are many preparation regimens for bowel cleansing. given their adverse effects, none of them have been considered perfect by the endoscopists. the aim of this study was to compare the effects of two bowel cleansing regimens on clean colonic preparation the subjects'well being and electrolyte balance. materials andmethods: atotal number of 280 patients were randomly assigned to...

All the liposome preparation protocols, which involve drug encapsulation are multi-step processes, i.e. they consist of one or several steps of preparation and homogenization. The conditions of converting all lipids into vesicles smaller than 200 nm were determined by replacing ultrasonication with mechanical stirring of the buffer and solution of lipids in a low-boiling point organic solvent o...

As shown especially for the transformation of the thermally rather unstable α-D-galactofuranosylnitromethane to α-D-galactofuranosylmethylamine, the electron-transfer reduction of glycosylnitromethanes with ferrous ions in aqueous ammonia at room temperature is a very mild and convenient alternative of the preparation of the corresponding glycosylmethylamines. Also βL-rhamnopyranosylmethylamine...

Nanoparticles are nowadays largely investigated in the field of drug delivery. Among nanoparticles, protein-based particles are of paramount importance since they are natural, biodegradable, biocompatible, and nontoxic. There are several methods to prepare proteins containing nanoparticles, but only a few studies have been dedicated to the preparation of protein- based nanoparticles. Then, the ...

Two methods of preparation of urine for cytology were compared retrospectively. In method 1 cells in the urine were fixed after the preparation of the smear; in method 2 the cells were fixed before smear preparation. Urine cytology reports were correlated with subsequent histological analysis. The specificities of urine cytology using both methods were high (99%). The sensitivity using method 1...
