Objectives: Drug injection carries with it many risks and therefore it is important to understand the initiating factors of injection and its origins. Thus,  the purpose of this study was to identify factors associated with the initiation of injection drug use among substance abusers. Methods:  Study method was a cross-sectional study. The research statistics universe constitutes a...

Diastolic phase of cardiac function is associated with lower arterial flow and hence higher concentration of intra arterially injected drug is achieved at the site of injection. It is herein postulated that drugs show higher efficacy when injected during the diastolic phase of cardiac function. It is also postulated that this benefit cannot be achieved when the drug is injected with higher rate...

Background: Due to the importance of medical studies, researchers of this field should be familiar with various types of statistical analyses to select the most appropriate method based on the characteristics of their data sets. Classification and regression trees (CARTs) can be as complementary to regression models. We compared the performance of a logistic regression model and a CART in predi...

pharmacokinetics of ceftriaxone was studied in buffalo calves (bubalus bubalis) after single intravenousand intramuscular administration of 10 mg/kg body weight. the drug concentrations in plasma samples weremeasured by high performance liquid chromatography with uv detection. following intravenousadministration, the drug was rapidly distributed (cpo: 106.5 ± 9.64 μg/ml; t1/2α: 0.09 ± 0.01 h; v...
