New findings on "successful aging"

What, exactly, does "successful aging" mean? For more than a half century, researchers and gerontologists have argued whether successful aging is better defined subjectively or objectively (physical disease-related disability or mental decline). Answering this question is more than an academic exercise. As the first members of the famed "baby boom generation" reach age 65, understanding what it means to remain healthy and independent in later life could have an enormous impact on health care delivery and medical policy.

Study reveals link between allergies, asthma and old age

Mistaken for illnesses like bronchitis and emphysema, exacerbated by medications like aspirin, and overlooked by patients and doctors alike, asthma is a common and highly treatable condition in older adults. And while allergies tend to decrease with age, they also are frequently disregarded as a potential cause of misery for the elderly.

hBD-3 biomarker helps early stage detection of oral cancer

Detecting oral cancer in its earliest stages can save the lives of the nearly 40,500 people diagnosed annually. But early detection has been difficult. Case Western Reserve University School of Dental Medicine researchers discovered a biomarker, called human beta defensin-3 (hBD-3), which may serve as an early warning. The defensin is present in all oral cancers and associated with the early stages of oral cancer.

Osteocalcin hormone can regulate glucose levels: Research

Researchers led by Columbia University Medical Center have discovered that the skeleton plays an important role in regulating blood sugar and have further illuminated how bone controls this process. The finding, published in Cell, is important because it may lead to more targeted drugs for type 2 diabetes.

Gene expression profiling may provide molecular diagnostic tool to diagnose depression

Blood tests have been extremely important tools aiding doctors in making medical diagnoses and in guiding the treatment of many diseases. However, psychiatry is one area of medicine where there are few diagnostic blood tests.New scientific fields may someday generate blood tests that can be used for these purposes. Some of the areas under increasingly intensive study are genetics, the study of variations in the genes that can be extracted from blood cells, and genomics like proteomics, the measurement of the levels of specific proteins in the blood, and gene expression profiling, which measures the levels of RNA produced from DNA as an indication of the level of the "activity" of particular genes.

African ancestry associated with triple-negative breast cancer: Study

A new study finds that African ancestry is linked to triple-negative breast cancer, a more aggressive type of cancer that has fewer treatment options.Researchers at the University of Michigan Comprehensive Cancer Center found that, among women with breast cancer, 82 percent of African women were triple negative, 26 percent of African-Americans were and 16 percent of white Americans were.

Protein parkin essential for hypothalamic neurons recovery in Parkinson's disease patients

A Michigan State University researcher is working to uncover how a protein known as parkin may help nerve cells fight off damage from Parkinson's disease, a strategy that could lead to new therapies for the degenerative ailment.

Drugs that activate SIRT1 hold potential to combat Alzheimer's: Study

MIT biologists report that they have discovered the first link between the amyloid plaques that form in the brains of Alzheimer's patients and a gene previously implicated in the aging process, SIRT1.

Three toxins in food identified as triggers to gluten intolerance: study

Coeliac disease cause by intolerance to gluten present in food and drinks like bread, pasta, cereals, biscuits and beer commonly affects many people all over the world. This affects 1 percent of all people in UK, especially women. Patients are advised to stay away from gluten to prevent damage to their intestines. In spite of this in five years most patients develop problems in their intestines. A gluten free diet is also difficult to maintain. Possible symptoms include diarrhoea, nausea and vomiting, recurrent stomach pain, tiredness, headaches, weight loss and mouth ulcers. These may be mild, moderate or severe in different individuals.

Towards a cure: HIV reservoirs and strategies to control them

Can HIV infection ever be cured? The prospect of efficiently controlling HIV persistence in infected persons was the topic of a high-level, two-day meeting of researchers gathered here on the eve of AIDS 2010, the biennial international conference of HIV researchers, funders, policy-makers and advocates.

Painters at higher risk of developing bladder cancer: Study

A new study by the International Agency for Research on Cancer (IARC) has provided further evidence that professional painters may face a higher risk of developing bladder cancer than the general population.

New understanding on insulin resistance, action of diabetes drugs may lead to safer medication

A new understanding of insulin resistance and the action of diabetes drugs such as Avandia and Actos could pave the way for improved medications that are more selective and safer, say scientists from Dana-Farber Cancer Institute and The Scripps Research Institute.Our findings strongly suggest that good and bad effects of these drugs can be separated by designing second-generation drugs that focus on the newly uncovered mechanism, said Bruce Spiegelman, PhD, of Dana-Farber, senior author on a report appearing in the July 22 issue of Nature.

Strong feelings alter one's ability to resist temptations: Study

While it may be convenient to add in a trip to the grocery store after a good workout at the gym, a recent study confirms it may not be the best idea for your waistline.The study in the current issue of the Journal of Consumer Research indicates mood, positive or negative, has a noticeable effect on the choices made by consumers. Co-authors Alexander Fedorikhin, of Indiana University's Kelley School of Business Indianapolis, and Vanessa Patrick, of the University of Houston, conducted three experiments to show how strong feelings alter one's ability to resist temptations.

Predator-released chemicals function as warning signals for egg-laying mosquitoes

A scientific breakthrough might assist in the fight against mosquitoes. New research carried out at the University of Haifa in collaboration with researchers from other universities has chemically identified, for the first time, compounds released by mosquitoes' natural aquatic predators that function as warning signals for egg laying mosquitoes. Introducing these natural chemicals into mosquito breeding sites will cause the mosquitoes to sense risk of predation to their progeny and avoid laying their eggs there.

Genomics researchers study role of protein in metabolic disorders, heart disease

Studying a protein already known to play an important role in type 2 diabetes and cancer, genomics researchers have discovered that it may have an even broader role in disease, particularly in other metabolic disorders and heart disease. In finding unsuspected links to other disease-related genes, the scientists may have identified future targets for drug treatments.

VA approves $2.8M for Gulf War Veterans' illness research program

The Department of Veterans Affairs (VA) has approved $2.8 million to fund three new research projects that focus on testing or developing new treatments for illnesses affecting Veterans who served in the Gulf War 1990-1991. The research incorporates recommendations of the department's Gulf War Veterans' Illnesses Task Force.

Chaos models may help predict cardiac arrhythmias, say researchers

Chaos models may someday help model cardiac arrhythmias -- abnormal electrical rhythms of the heart, say researchers in the journal CHAOS, which is published by the American Institute of Physics. In recent years, medical research has drawn more attention to chaos in cardiac dynamics. Although chaos marks the disorder of a dynamical system, locating the origin of chaos and watching it develop might allow researchers to predict, and maybe even counteract, certain outcomes.
