Real-time wearable telecardiology from representative signals.

Electrocardiograms and other similar techniques (e.g. Photoplethysmograph) are very effective tools for the detection of cardiac abnormalities.

Child care provider training and a supportive feeding environment in child care settings in 4 states, 2003.

Introduction: Strategies to prevent adult chronic diseases, including obesity, must start in childhood. Because many preschool-aged children spend mealtimes in child care facilities, staff should be taught supportive feeding practices for childhood obesity prevention. Higher obesity rates among low-income children suggest that centers providing care to these children require special attention.

Contraception choices in a cohort of HIV+ women in the era of highly active antiretroviral therapy.

Background: The study was conducted to determine whether increased desire for fertility coupled with increased awareness of reduction in mother-to-child HIV transmission (MTCT) with increased availability and use of highly active antiretroviral therapy (HAART) has been associated with reduction in use of tubal sterilization as a form of contraception among women infected with HIV.

Study Design: One hundred HIV+ women, 18 to 45 years of age, receiving care at university-affiliated HIV facilities between October 2008 and February 2009, were surveyed about their contraceptive knowledge and practices. We performed descriptive analysis of population characteristics to determine contraception choices and fertility desires following initiation of HAART.

Determination of the potential for release of mercury from combustion product amended soils: part 2--coal fly ash generated stabilized soil and degradation products.

The potential for mercury (Hg) releases to the air and water from three soils, two subbituminous coal fly ashes, and mixtures of these materials as stabilized soil was assessed. In addition, the potential for Hg release from crushed stabilized material mixed into soil simulating degradation over time was investigated. In general, atmospheric Hg deposition was measured for the ash and materials made using the ash with the higher Hg concentration (ash 1, 0.

Dscam guides embryonic axons by Netrin-dependent and -independent functions.

Developing axons are attracted to the CNS midline by Netrin proteins and other as yet unidentified signals. Netrin signals are transduced in part by Frazzled (Fra)/DCC receptors. Genetic analysis in Drosophila indicates that additional unidentified receptors are needed to mediate the attractive response to Netrin.

Determination of the potential for release of mercury from combustion product amended soils: Part 1--Simulations of beneficial use.

This paper describes a project that assessed the potential for mercury (Hg) release to air and water from soil amended with combustion products to simulate beneficial use. Combustion products (ash) derived from wood, sewage sludge, subbituminous coal, and a subbituminous coal-petroleum coke mixture were added to soil as agricultural supplements, soil stabilizers, and to develop low-permeability surfaces. Hg release was measured from the latter when intact and after it was broken up and mixed into the soil.

Assessing the source of mercury in foliar tissue of quaking aspen.

Foliar accumulation of mercury has been demonstrated to occur as plants leaf out, yet the primary source of this mercury is not known. Using closed-system growth chambers, uptake of mercury by quaking aspen (Populus tremuloides) foliage was measured over time as a function of soil mercury concentrations (0.01, 6.

Influence of pH treatments on survival of Escherichia coli O157:H7 in continuous cultures of rumen contents.

The pH (i.e., 5.
