The Capability of Raman Microspectroscopy to Differentiate Printing Inks.

This study applies Raman microspectroscopy to differentiate the chemical components in printing inks of different brands, colors, and type using the 532 nm and 785 nm excitation wavelengths. Spectra were collected from 319 inks (78 inkjet, 76 toner, 79 offset, and 86 intaglio) representing various colors. Comparisons were performed to calculate discrimination capability percentages for each ink type.

Prolactin serum concentrations during aripiprazole treatment in youth.

Objective: This study aimed to: document the extent of the reduction of serum prolactin (PRL) levels induced by aripiprazole (ARI) treatment in children and adolescents, compare this effect by age group, and shed light on this phenomenon.

Methods: PRL serum levels in unmedicated subjects were compared to those in subjects treated with aripiprazole to calculate the rate of subnormal PRL levels during aripiprazole treatment. Next, a literature search was performed to better understand the effects of dopaminergic drugs on PRL levels by age group.

Age-grouped differences in bipolar mania.

Objective: This review of published studies compares scores on individual items of mania rating scales that systematically recorded symptom severity in persons diagnosed with bipolar disorder to identify age-grouped differences.

Methods: An extensive literature search identified item scores from mania rating scales, with a particular emphasis on baseline Young Mania Rating Scale (YMRS) item scores in published double-blind, placebo-controlled studies of bipolar I manic disorder. These baseline YMRS item scores were assessed as a proportion of the total YMRS score and compared by age group.

Socioepidemiology of cigarette smoking among Cambodian Americans in Long Beach, California.

We examined the prevalence of cigarette smoking among Cambodian Americans in Long Beach, California. A stratified random sample of 1,414 adult respondents was selected from 15 census tracts with high concentrations of Cambodian Americans. The prevalence of current smokers was 13.

Analysis of acculturation, sex, and heavy alcohol use in Latino college students.

24% of 917 students at California State University Long Beach who completed an alcohol use survey in 2002 (73% response) identified themselves as Latino. Because measures of acculturation reported in most adult studies positively correlated with alcohol use and sex, it was hypothesized that these associations might also apply to Latino college students. With increasing levels of acculturation, women but not men in this Latino college sample reported significantly greater occurrence of heavy drinking, positive attitudes about drinking, and perception that most of their friends use alcoholic beverages.
