Low-level chemical sensitivity: current perspectives

Low-level chemical sensitivity: current perspectives.

Low-level chemical sensitivity: implications for research and social policy.

There is increasing evidence that human exposure to levels of chemicals once thought to be safe--or presenting insignificant risk--are, in fact, harmful. So-called low-level exposures are now known to be associated with adverse biological effects including cancer, endocrine disruption, and chemical sensitivity. This requires that we change both (1) the way we design research linking chemicals a...

Origin, Current Status, and Future Perspectives of Chemical Cytometry

Cells are the organizing units of life. However, not all cells are alike; individual cells can differ significantly from their neighbors. These differences can be due to genetic, environmental, cell cycle, or stochastic effects, and these differences can have profound effects upon the behavior of a cellular population. A knowledge of the function and composition of individual cells will lead to...

Prevention of postpartum hemorrhage in low-resource settings: current perspectives

BACKGROUND Postpartum hemorrhage (PPH) is the leading cause of maternal death in low-income countries and is the primary cause of approximately one-quarter of global maternal deaths. The purpose of this paper is to provide a review of PPH prevention interventions, with a particular focus on misoprostol, and the challenges and opportunities that preventing PPH in low-resource settings presents. ...

A Low Temperature Sensitivity Switched-Capacitor Current Reference

A current reference with low temperature sensitivity based on a switched-capacitor technique has been developed. The implementation is targeted for a 0.18μ CMOS process. HSPICE simulations using level 49 models valid over a wide temperature range were used to verify the design. The simulation results predict variations of less than 0.029% over a temperature range of –40 °C to 125 °C.
