Particle transfer and adherence to human skin compared with cotton glove and pre-moistened polyvinyl alcohol exposure sampling substrates.

Measurement of skin exposure to particles using interception (e.g., cotton gloves) and removal (e.

The State of the Science of Preterm Birth: Assessing Contemporary Screening and Preventive Strategies.

Preterm birth remains a leading cause of morbidity and mortality during the perinatal and neonatal periods. Now affecting approximately 1 in 10 births in the United States, preterm birth often occurs spontaneously and without a clear etiology. Careful assessment of risk factors, however, identifies vulnerable women allowing targeted interventions such as progestogen therapy and cerclage.

Dermal exposure potential from textiles that contain silver nanoparticles.

Background: Factors that influence exposure to silver particles from the use of textiles are not well understood.

Objectives: The aim of this study was to evaluate the influence of product treatment and physiological factors on silver release from two textiles.

Methods: Atomic and absorbance spectroscopy, electron microscopy, and dynamic light scattering (DLS) were applied to characterize the chemical and physical properties of the textiles and evaluate silver release in artificial sweat and saliva under varying physiological conditions.
