"": Unaccompanied Youth Workers' Emergent Frame of Reference and Health in the United States.

Relying on in-depth interviews and ethnographic data in Los Angeles, California, this study examines the health experiences of unaccompanied, undocumented Latin American-origin immigrant youth as they come of age as low-wage workers. Findings demonstrate that unaccompanied, undocumented youth undergo cumulative physical and mental health disadvantages in the United States's secondary labor market and during critical developmental life stages while lacking the parental monitoring and guidance to navigate them. Developing comparisons between their past and present living conditions and between themselves and other youth in Los Angeles-what I refer to as an -youth workers come to perceive family disruptions, and especially separation from their parents, as the most salient factor affecting their health.

ABCB1/4 gallbladder cancer risk variants identified in India also show strong effects in Chileans.

Background: The first large-scale genome-wide association study of gallbladder cancer (GBC) recently identified and validated three susceptibility variants in the ABCB1 and ABCB4 genes for individuals of Indian descent. We investigated whether these variants were also associated with GBC risk in Chileans, who show the highest incidence of GBC worldwide, and in Europeans with a low GBC incidence.

Methods: This population-based study analysed genotype data from retrospective Chilean case-control (255 cases, 2042 controls) and prospective European cohort (108 cases, 181 controls) samples consistently with the original publication.

Variation in dental morphology and inference of continental ancestry in admixed Latin Americans.

Objectives: To investigate the variation in dental nonmetric traits and to evaluate the utility of this variation for inferring genetic ancestry proportions in a sample of admixed Latin Americans.

Materials And Methods: We characterized a sample from Colombia (N = 477) for 34 dental traits and obtained estimates of individual Native American, European, and African ancestry using genome-wide SNP data. We tested for correlation between dental traits, genetic ancestry, age, and sex.

Microbial Community and Metabolic Activity in Thiocyanate Degrading Low Temperature Microbial Fuel Cells.

Thiocyanate is a toxic compound produced by the mining and metallurgy industries that needs to be remediated prior to its release into the environment. If the industry is situated at high altitudes or near the poles, economic factors require a low temperature treatment process. Microbial fuel cells are a developing technology that have the benefits of both removing such toxic compounds while recovering electrical energy.

Effect of isoniazid on antigen-specific interferon-γ secretion in latent tuberculosis.

Treatment of persons with latent tuberculosis (TB) infection at greatest risk of reactivation is an important component of TB control and elimination strategies. Biomarkers evaluating the effectiveness of treatment of latent TB infection have not yet been identified. This information would enhance control efforts and assist the evaluation of new treatment regimes.
