A University of Kansas researcher has successfully demonstrated a method to convert grass, stalks, and farm byproducts into sugar for use as a primary component in fuel for diesel engines. The alternative fuel mixture is estimated to cost less than traditional diesel fuel and has already been tested in conventional diesel engines.
A new study reveals that premature infants born to women with mild high blood pressure may have a lower incidence of respiratory distress syndrome compared to those born to mothers with severe hypertension. Infants born to mothers with mild hypertension tend to mature faster, reducing the risk of chronic lung problems.
A diet high in fruits, vegetables, low-fat dairy products and other low-fat foods significantly lowers blood pressure, according to a multicenter study. The combination diet reduced systolic blood pressure by an average of 5.5 mm Hg and diastolic pressure by an average of 3.0 mm Hg within two weeks.
Researchers found that people with only occasionally elevated blood pressure already had blood vessel abnormalities before the onset of sustained high blood pressure. The study suggests that vascular changes may lead to hypertension, rather than vice versa, in people.
A computer-based system aims to establish a scientific basis for equitable and sustainable water resources management. The integrated decision support system uses hydrometeorological data to simulate the response of rivers and reservoirs to different climatic inputs, water and power demands, and decision policies.
Researchers at Emory University report a link between mental stress and cardiovascular damage. They suggest that chronic stress can lead to inflammation and oxidative stress, ultimately damaging the heart. The study's findings have implications for understanding the causes of cardiovascular disease in individuals with fragile X syndrome.
The Georgia Institute of Technology has established a new Test and Evaluation Research and Education Center (TEREC) to find less expensive ways to test new technologies. The center will provide an international focal point for T&E research and education, and a catalyst for the invention of the future of the discipline.
Researchers found a 5% increase in sun-protective behaviors among beachgoers who received personalized sun-protection strategies, based on their stage of behavioral change. The study suggests that beaches are an effective site for reaching high-risk sunbathers and promoting behavior change.
Researchers at Purdue University developed chilled-aeration technology to control pests in stored grains without using chemical fumigants. The method is economically competitive with fumigation and reduces total energy consumption. For fresh-picked produce, the technology increases marketability by cooling it immediately after harvesting.
Two NIH-supported studies show that lifestyle modifications, such as a low-fat, high-fiber diet, can substantially reduce blood pressure in adults. The findings also suggest that weight loss and reduced dietary sodium can safely reduce the need for antihypertensive medication in older patients.
