Despite previous research suggesting that older adults are more distractible, new research shows they are no more distractible than younger adults when asked to focus their attention on their sense of sight or sound, or when asked to switch their attention from one sense to the other.
The American Heart Association awarded its Clinical Research Prize to a Harvard researcher for identifying destructive structural changes in the diseased heart and leading clinical trials showing that lifesaving therapies can limit damage.
The National Science Foundation (NSF) has awarded an interdisciplinary team of five Stevens Institute of Technology researchers a four-year, $1 million grant to develop “smart, self-assembling nano-biomaterials that can control whether bacteria will adhere to synthetic surfaces, allowing for carefully targeted control over microscopic processes that occur within the human body.
SMA is the second most prevalent genetic cause of infant death in the UK, after cystic fibrosis. Studies show that between 1:50 and 1:34 of the population are carriers of the disease, and that it affects in the region of 1:10,000 children born in the UK. In the USA, 1:40 are carriers and 1:6,000 children are affected by the disease.
When a host cell is infected with HIV, the virus brings its own genetic material into the host cell. This cell then replicates, reads the viral RNA, and uses it as a blueprint to produce more viral proteins. Complete viruses are then released to attack the next cells.
Treatment should be offered to all people with a particular rare lung condition, regardless of whether or not they show symptoms of it, say researchers and doctors behind a new study published today.
Experts don’t dispute the important role that diet and activity play in maintaining a healthy weight. But can poor eating habits and a less active lifestyle fully explain the prevalence of obesity in the United States today? That question has led some researchers to ask whether there might be other causes for this serious problem. In the October issue of Mayo Clinic Proceedings, researcher Richard Atkinson, M.D., asserts that there is a growing body of evidence demonstrating that viruses may play a role in causing obesity in humans.
People older than 60 with high blood pressure are less likely than other groups of patients to receive advice from their doctors about lifestyle modifications that can help lower their blood pressure, a study by UNC researchers concludes.
Despite the availability of life-saving antiretroviral treatment, people infected with HIV (human immunodeficiency virus) continue to die and suffer from complications of AIDS, mainly due to delayed diagnosis and initiation of treatment. A researcher at the Albert Einstein College of Medicine of Yeshiva University and colleagues at Yale University have shed light on why this problem persists. They report their findings in the November issue of the journal Medical Care.
Platinum complexes such as the well-known cisplatin are powerful antitumor medications. They cross the cell membrane and reach the nucleus, where they attach to DNA and stop cell growth. But how does cisplatin get to the nucleus? Italian researchers have now proven that a copper transport protein may play a critical role. In the journal Angewandte Chemie, they present their hypothesis about the transport mechanism.
