BACKGROUND/AIM Saliva is a body fluid which, like serum, can be used for determination of concentrations of certain drugs, both in pharmacotherapy as well as in acute poisonings. The aim of this study was to determine carbamazepine concentrations in both saliva and serum in acute poisoning in order to show if there is a correlation between the obtained values, as well as to monitor toxicokineti...
Dispersive liquid-liquid microextraction method (DLLME) combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was used to determine thiamine (B1), nicotinamide (B3) and pyridoxine (B6) in sour cherry juice. This method was rapid, simple and sensitive. Separation was accomplished using a C18 column. The optimum chromatographic conditions were found to be: mobile ph...
Lung abcess is a rarely identified suppurative infection that has air-liquid level bigger 2 cm diameter on pulmonary graphy. It should especially be considered in the case of treatment-refractory pneumonic infections of persons with chronic diseases. In order to point out to the importance of this issue, this study presents a case of pulmonary abcess identified in a patient who was followed up ...
The high mobility group (HMG) of nonhistone proteins have been investigated using two high performance liquid chromatographic techniques (HPLC). Reversed-phase HPLC under conditions of 50 mM triethylamine adjusted to pH 2.2 with phosphoric acid (solvent A) and 95% acetonitrile in water (solvent B) was used to separate proteins primarily on the basis of differences in the overall hydrophobi...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
