THE onset of Alzheimer's disease can be slowed and some of its symptoms curbed by a natural compound that is found in pomegranate. Also, the painful inflammation that accompanies illnesses such as rheumatoid arthritis and Parkinson's disease could be reduced, according to the findings of a two-year project headed by University of Huddersfield scientist Dr Olumayokun Olajide, who specialises in the anti-inflammatory properties of natural products. Now, a new phase of research can explore the development of drugs that will stem the development of dementias such as Alzheimer's, ...

Milk allergy is frequently confused with lactose intolerance. However, these are two entirely different mechanisms that occur in the body. People with lactose intolerance do not digest lactose properly because they lack an enzyme known as lactase. In the case of the potentially much more dangerous cow milk allergy, however, the body's immune system attacks milk proteins with its own IgE antibodies. According to statistics, about two to three percent of children in Europe suffer from a genuine milk allergy. Less adults are diagnosed with the disease. The formation of so-called ...

Many recall the dramatic images of nurses at New York University's Langone Medical Center (NYULMC) heroically evacuating over three hundred patients, carrying many including the youngest and most vulnerable down flights of stairs during the power outage resulting from the storm surge generated by Hurricane Sandy. Now, a recent study by researchers at the New York University Colleges of Nursing (NYUCN) and of Dentistry (NYUCD), published in The Journal of Urban Health examines the impact on NYULMC nurses' post-Sandy deployment to help address patient surge in eight local ...

Women treated for the cancer Hodgkin lymphoma will be able to better understand their risks of future infertility after researchers estimated their risk of premature menopause with different treatments. The findings, set out in the Journal of the National Cancer Institute, are based on the experience of more than 2,000 young women in England and Wales treated for the cancer over a period of more than 40 years. Previous research has suggested that women with Hodgkin lymphoma who receive certain types of chemotherapy or radiotherapy are at increased risk of going through ...

3β-Hydroxysteroid-Δ24 reductase (DHCR24) is a multifunctional enzyme that localizes to the endoplasmic reticulum and has neuroprotective and cholesterol-synthesizing activities. DHCR24 overexpression confers neuroprotection against apoptosis caused by amyloid β deposition. Dr. Xiuli Lu and colleagues from Liaoning University in China constructed two recombinant adenoviruses (Ad-rSYN1-DHCR24-myc and Ad-hSYN1-DHCR24-myc) that drive DHCR24 expression specifically in neuronal cells. They also found that adenovirus transfection inhibits apoptosis through scavenging ...

Cigarettes with very low levels of nicotine may reduce addiction without increasing exposure to toxic chemicals, according to a new study from the University of Waterloo. The study published in the journal Cancer Epidemiology monitored the smoking behaviours of 72 adults as they switched to three types of cigarettes with markedly reduced nicotine levels. Unlike when smokers switch between conventional cigarette brands—all of which have very similar levels of nicotine content—the study found no change in participants' puffing behaviour, number of cigarettes consumed ...

New research by a team of UK and European-based astronomers is helping to solve the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year. The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year by chance at the University of London Observatory. These phenomena are extremely important to study because they provide key information about our universe, including how it is expanding and how galaxies evolve. The new research into its cause, published ...

Citizen scientists are saving the lives of people living in the shadow of deadly volcanoes according to new research from the University of East Anglia. A new report published today reveals the success of a volunteer group set up to safeguard communities around the 'Throat of Fire' Tungurahua volcano in the Ecuadorian Andes. More than 600 million people live close to active volcanoes worldwide.

In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming. Now scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters ...

In a new study published in Nature Communications, research scientists from Uppsala University present for the first time a large-scale study of the significance of genetic, clinical and lifestyle factors for protein levels in the bloodstream. The results of the study show that genetics and lifestyle are determining factors for protein levels, a discovery which greatly influences the possibilities for using more biomarkers to identify disease. Biomarkers used for diagnosing disease should preferably indicate variations in protein levels only for those individuals who ...

Stanford, CA—Everyone's heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized.
