Pets and related allergens modify the association between early life DEHP exposure and respiratory outcomes in children.

Introduction: Throughout the perinatal period children are exposed to complex mixtures, including indoor chemicals such as phthalates, and biological agents. However, few studies focus on interactions between early-life co-exposures to shed light on how co-exposures modify their individual effects. Therefore, our study aims to assess whether early-life exposure to pets and related biological agents, namely pet allergens and endotoxin, modifies the association between di-(2-ethylhexyl) phthalate (DEHP) and asthma and wheeze in preschoolers to gain insight into interactions.

The development and application of a new method for quantifying total atmospheric sulfur in the Alberta Oil Sands.

Continuous ambient sulfur measurements are routinely conducted around the globe at numerous monitoring sites impacted by industrial sources such as gas and oil processing facilities, pulp and paper mills, smelters, sewage treatment facilities, or concentrated animal feeding operations, as well as natural sources such as volcanoes. Various jurisdictions have or plan to establish Air Ambient Quality Objectives/Guidelines/Standards for Total Reduced Sulfur (TRS) based on odor perception and/or health effects. A conventional TRS monitoring technique is widely used, but few studies have looked at potential biases in the resulting TRS measurements.

Cyclin-dependent kinase 13 is indispensable for normal mouse heart development.

Congenital heart disease (CHD) has an incidence of approximately 1%. Over the last decade, sequencing studies including large cohorts of individuals with CHD have begun to unravel the genetic mechanisms underpinning CHD. This includes the identification of variants in cyclin-dependent kinase 13 (CDK13), in individuals with syndromic CHD.

Assessment of long-term exposure to traffic-related air pollution: An exposure framework.

Background: Exposure to ambient air pollution is associated with morbidity and mortality, making it an important public health concern. Emissions from motorized traffic are a common source of air pollution but evaluating the contribution of traffic-related air pollution (TRAP) emissions to health risks is challenging because it is difficult to disentangle the contribution of individual air pollution sources to exposure contrasts in an epidemiological study.

Objective: This paper describes a new framework to identify whether air pollution differences reflect contrasts in TRAP exposures.

Creativity, agency, and stability: Perceptions of Canadian musicians working across the cultural domains.

This research study aims to illuminate Canadian musicians' portfolio careers across the cultural domains. Previous research has highlighted the career paths of music graduates directly after graduation, and other research has highlighted the experiences of well-known performers or pedagogues. However, little is known about music graduates who persist and establish careers in music.
