The role of young adolescents' perception in understanding the severity of exposure to community violence and PTSD

This study seeks to (a) identify and measure the lifetime exposure to community violence of 137 African American and Latino middle school students from a low income neighborhood and apply numerical weights to each violent event; (b) examine the relationship between the objective severity of child self reported violence exposure and the child's subjective perception of the most bothersome event; and (c) examine the relationship between child's exposure and posttraumatic stress disorder (PTSD). Results highlight that students' designation of their most bothersome exposure to community violence did not correspond to the most severe violent event they experienced. Regression analyses reveal the weight of the most severe event explains a larger percentage of the variance in PTSD compared with the relationship to victim, level of exposure, weight of the most bothersome exposure, and cumulative weight of all exposure. This study underscores the importance of assessing a child's perception of violent events.     

Determination of phosphoglucomutase (PGM1), acid phosphatase (ACP), and esterase D (ESD) in human bloodstains by hybrid isoelectric focusing (HIEF)

PGM1, ESD, and ACP were determined in bloodstain extracts by isoelectric focusing (IEF) with carrier ampholytes (CA) and HIEF. HIEF yields superior results in PGM typing from bloodstain extracts, whereas for ESD and ACP typing isoelectric focusing with carrier ampholytes seems to be the method of choice.     

A comparative pharmacokinetic study of ethanol in the blood, vitreous humour and aqueous humour of rabbits

The pharmacokinetics of ethanol in the blood, vitreous humour and aqueous humour of the rabbit after intravenous administration of single dose have been compared. Ethanol levels were determined by gas-liquid chromatography. Certain parallelism between ethanol levels in these body fluids were observed after 80 min.
