What a mix! Volatile organic compounds and worker exposure in small business beauty salons in Tucson, Arizona.

Introduction: Small business beauty salons have volatile organic compounds (VOCs) in their workplace air. VOCs are present as ingredients in beauty or hair products. They may also form because of chemical reactions, where thermal-styling elements accelerate the volatilization of these compounds.

Quantification and Analysis of Micro-Level Activities Data from Children Aged 1-12 Years Old for Use in the Assessments of Exposure to Recycled Tire on Turf and Playgrounds.

Background: There are growing health concerns about exposure to toxicants released from recycled tire rubber, which is commonly used in synthetic turf and playground mats. To better estimate children's exposure and risk from recycled tire rubber used in synthetic turf and playground mats, there is a need to collect detailed accurate information on mouthing activity and dermal contact behaviors. The objective of this study was to quantify and analyze micro-level activity time series (MLATS) data from children aged 1-12 years old while playing (non-sport-related games) at turf-like locations and playgrounds.

Race and Gender-Based Perceptions of Older Adults: Will the Youth Lead the Way?

Background: Older individuals encounter the greatest racial/gender biases. It is unknown whether younger generations, who often lead culture shifts, have racial and gender biases against older populations.

Methods: Using Amazon's Mechanical Turk's crowdsourcing, we identified how an individual's race and gender are associated with perceptions of individuals aged mid-60s.

Usual Dietary Intake and Adherence to Dietary Recommendations among Southwest American-Indian Youths at Risk of Type 2 Diabetes.

Background: American Indians are disproportionately affected by obesity and diabetes, and American-Indian youths have the highest prevalence of obesity and diabetes among all ethnic groups in the USA.

Objectives: The purposes of this study were to assess the usual dietary intake in American-Indian youths who attended a wellness camp program; adherence to the Dietary Guidelines for Americans 2015-2020 (DGA) and to the Healthy People 2020 Objectives; and to compare pre- and postcamp reported diets.

Methods: A total of six 24-h dietary recalls were conducted in person with American-Indian youths (aged 10-15 y;  = 26) from 3 different Southwest tribes.

Metabolomic profiling distinction of human nonalcoholic fatty liver disease progression from a common rat model.

Objective: Characteristic pathological changes define the progression of steatosis to nonalcoholic steatohepatitis (NASH) and are correlated to metabolic pathways. A common rodent model of NASH is the methionine and choline deficient (MCD) diet. The objective of this study was to perform full metabolomic analyses on liver samples to determine which pathways are altered most pronouncedly in this condition in humans, and to compare these changes to rodent models of nonalcoholic fatty liver disease (NAFLD).
