Researchers discovered that syphilis increases HIV transmission by activating immune cells through bacterial membrane lipoproteins. This understanding could lead to treatments to slow HIV disease progression. The study found a plausible molecular explanation for why people with syphilis are more likely to transmit or contract HIV.
A new study reveals that body fat is significantly associated with increased blood pressure, particularly in women. Researchers found that those who gained more fat over time also experienced higher increases in blood pressure.
Research found genetic make-up plays a significant role in determining individual responses to cholesterol-lowering drugs like Lovastatin. A gene variant associated with unresponsiveness was identified, suggesting that 1 in 12 individuals may not benefit from the treatment.
A study finds that living in poorer communities is associated with worse health, even for individuals with high education and income levels. The research suggests that community characteristics play a significant role in determining health outcomes.
Researchers use high-tech Ground Penetrating Radar to uncover ancient shell middens, revealing Native American cooking practices and sea-level changes in the area. The technique allows for non-invasive exploration of saltwater marshes, providing new insights into the region's history.
Cornell University scientists demonstrate a concept that could be used in ultra-small electronic devices by isolating a single oxygen molecule and causing it to rotate on command. The experiment provided basic research information about the nature of the chemical bond formed when an oxygen molecule is adsorbed to a platinum surface.
A study found that nearly one in five organ donor families would reconsider donating organs if given the chance. Factors such as prior discussion with family members, education level, and religion influenced satisfaction with donation decisions.
A recent study found that soy phytoestrogens provided equivalent stroke-prevention benefits to standard Premarin therapy in postmenopausal monkeys. The treatment reduced internal carotid artery atherosclerosis by more than half, preventing the development of an 'atherogenic plasma lipid profile'.
Researchers at Harvard Medical School found that a protein wireing the developing brain also prevents nerve cells from entering off-limits areas, and plays a role in blood vessel formation. This convergence of two processes may lead to new insights into cancer research and embryology.
A recent study published by the American Heart Association suggests that sex differences in heart disease risk may be attributed to an enzyme called hepatic lipase. Hepatic lipase activity was found to be higher in men than women, and researchers believe this enzyme plays a crucial role in lipid metabolism.
Scientists at Ohio University and Progenitor Inc. use a nonviral gene expression system to eliminate human cancer cells in animals, achieving a 60 percent tumor regression rate. The T7 system allows for transient gene expression and has been shown to be effective against various types of cancers.
