Capillary electrophoresis (CE) with indirect UV detection is an interesting analytical method for the analysis of drugs and pharmaceuticals. Good and reproducible capillary quality is needed to develop robust methods and to facilitate method transfer in CE. It is widely accepted that preconditioning procedures are indispensable in capillary electrophoresis in order to achieve reproducibility of...

abstract         background and objective: scientific evidence reveals that the density of skeletal muscle microcirculations decreases in the patients with chronic heart failure. therefore, this study aimed to determine the impact of submaximal aerobic exercise training on restoration of fast/slow-twitch muscle fibers microcirculation in rats with myocardial infarction.          methods: in thi...

background & importance: cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. we report a case of the spinal intradural cavernous angiomas of the lumbar spine. case presentation: a 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pain. ...

carvedilol is administered as a racemic mixture of the r(+)- and s(-)-enantiomers, although it was demonstrated that the two enantiomers exhibit different pharmacological effects and stereoselective pharmacokinetics. the aim of this study was the evaluation of several native and derivatized cyclodextrines as chiral selectors for the separation of carvedilol enantiomers. stereoselective interact...

abstract         background and objective: normal hemoglobin (hb) is formed of a heme group and a protein group known as globin. globin is made of four polypeptide chains and in hemoglobinopathies, the structure of one of these four polypeptide chain becomes abnormal. cellulose acetate method is a common way to differentiate haemoglobinopathies. inability to identify the components of hb low co...

The salt damage provoked by crystallization pressure due to growth inside a porous material requires certain supersaturation of the pore solution. itineraries build it are here revisited at one scale, through experiments allowing direct observations multistep processes as well visualization itself. We present phase transitions within silica micro-capillaries filled with Na-SO4 aqueous solution ...
