A new study shows a strong association between severe, untreated obstructive sleep apnea and the risk of elevated blood pressure despite the use of high blood pressure medications. The study involved patients who had cardiovascular risk factors or established heart disease and moderate or severe obstructive sleep apnea. Among participants prescribed at least three antihypertensives including a diuretic, resistantRead more

Adults smokers with limited education face a greater risk of stroke than those with a higher education, according to new research in the American Heart Association's journal Stroke. The combination of smoking and high blood pressure increased stroke risk the most, confirming earlier findings in numerous studies. In a multicenter Danish study, researchers defined lower education as grade school orRead more

 Iranian chemists from Sistan and Balouchestan University in association with researchers from the Tehran Science and Research Branch of the Islamic Azad University and the University of New South Wales in Australia produced toxic ion nanosorbents with high sorption capacity. High sensitivity of nanosorbents to low concentrations of toxic ions is among the advantages of the nanosorbents. Despite the commonRead more

Researchers who studied 100 twin pairs have identified a gene mutation that may allow the carrier to function normally on less than six hours of sleep per night. The genetic variant also appears to provide greater resistance to the effects of sleep deprivation. Researchers who studied 100 twin pairs have identified a gene mutation that may allow the carrier toRead more

Following another person's gaze can reveal a wealth of information critical to social interactions and also to safety. Gaze following typically emerges in infancy, and new research looking at preterm infants suggests that it's visual experience, not maturational age, that underlies this critical ability. The research is published in Psychological Science, a journal of the Association for Psychological Science. "ToRead more

- Iranian researchers used nanoparticles as quantum dots and presented a new, effective and sensitive method to study interaction between drug and DNA. Data obtained from this method can be used in the designing of anticancer drugs. Studying the interaction between drugs and DNA is important for designing more effective anticancer drugs and for better understanding of biological processes suchRead more

Only 35.5 percent of about 17,000 respondents in a latest survey are working out regularly and the biggest barrier is lack of facilities. A total of 87.7 percent of the respondents said there is no free fitness facility around, according to the survey report published Thursday. The majority of the respondents in this survey are below 44 as about 36.3Read more

Dental researchers are warning parents of the dangers of soft drinks, fruit juice, sports drinks and other drinks high in acidity, which form part of a "triple-threat" of permanent damage to young people's teeth. Dental researchers at the University of Adelaide are warning parents of the dangers of soft drinks, fruit juice, sports drinks and other drinks high in acidity,Read more

A toxic red tide continues to bloom and expand in the waters of the Gulf of Mexico as it nears the coast of South Florida. Officials say the maroon-tinged algae bloom is one of the largest Florida's waters have seen in a decade. Researchers with the Florida Wildlife and Conservation Commission, the University of South Florida and Mote Marine recentlyRead more
