HIV-prevention therapy could additionally benefit gay men

Washington D.C. [USA], Oct. 6 : The anti-HIV drug Truvada has proved to be very effective at preventing new infections when taken by people at high risk, who strictly adhere to the drug therapy regime.

A new study states the cost-effectiveness of this intervention, commonly known as pre-exposure prophylaxis (PrEP) and counts its additional benefits.

Discovery of new protein may help in early diagnosis of Alzheimer

WashingtonD.C [USA], Oct.1 : A recent research at Rush University Medical Center recognized pathologic protein in the brain which may play a larger role in the development of clinical Alzheimer's disease.

Author of the study, Bryan James, said the finding could help researchers to understand the cause of memory loss and lead to new ways to approach studying Alzheimer's disease.


Those with common cancer types are more likely to live for a decade: Study

Washington D. C. [USA], Sept. 17 : According to recent estimates drawn by the Office of National Statistics (ONS), people, who develop skin, breast and prostate cancers are most likely to survive 10 years after diagnosis.

Those who develop skin cancer are the most likely to still be alive a decade after their diagnosis, with 89.4 percent of sufferers able to expect this lifespan.


Social connectedness can escalate suicide risk: Study

Washington D.C. [USA], Sept. 11 : A new research showed that community characteristics play an important role in perpetuating teen suicide clusters and thwarting prevention efforts.

The study, conduicted by sociologists at the University of Chicago and University of Memphis, illustrates how the homogeneous culture and high degree of social connectedness of a community can increase suicide risk, particularly among teenagers.

Such conditions contribute to clusters in which a series of suicides happen around the same time and in close proximity.


New protein findings may lead to new class of antibiotics

Washingbton D.C. [USA], Sept. 3 : A first of its kind detailed research of atomic-level images of a peroxiredoxin has revealed a peculiar characteristic of the protein and might form the foundation for a new approach to antibiotics.

Scientists have used X-ray crystallography, a powerful technique that can reveal structures down to their individual atoms, to study the fundamental nature and behavior of this peroxiredoxin.

Peroxiredoxin is needed by all cells to help eliminate hydrogen peroxide, a toxin, and in normal cells this process is healthy and valuable.


Explanation found for Alzheimer's risk genes

Washington D.C., Aug. 18 : A recent study has identified a connection between ApoE4 gene and protein build-up associated with Alzheimer's that provides a possible biochemical explanation for how extra ApoE4 causes the disease.

For the uninitiated, for decades, scientists have known that people with two copies of a gene called apolipoprotein E4 (ApoE4) are much more likely to have Alzheimer's disease at age 65 than the rest of the population.


Mayo Clinic, collaborators strategise to use drugs to treat age-linked diseases and disabilities

Washington, Aug.17 : Rochester-based Mayo Clinic and members of the Geroscience Network have published six manuscripts that map strategies for taking new drugs that hold promise for treating multiple age-related diseases and disabilities.

According to Dr. James Kirkland, Director of the Mayo Clinic's Robert and Arlene Kogod Center on Aging, aging is the largest risk factor for most chronic diseases, including stroke, heart disease, cancer, dementias, osteoporosis, arthritis, diabetes, metabolic syndrome, blindness and frailty.


Possible link between the Zika virus- joint deformities in babies found

Washington D.C., Aug .10 : There might be a possible link between the Zika virus and rare, but severe, joint deformities in babies, said a study by scientists in Brazil.

It has led the experts to warn that the virus could be linked to a host of other problems in babies, some of which might only become apparent as they get older.

Microcephaly (a rare birth defect where a baby is born with an abnormally small head) and other severe fetal brain defects are the main features of congenital Zika virus syndrome.


Here`s how insurance status affects cancer survival

Washington D.C, Aug 8 : Men with testicular cancer, who were uninsured or on Medicaid, had a higher risk of death from what is normally a curable disease than insured patients, suggests two new studies.

Many studies have revealed barriers to cancer care associated with health insurance status. Using population-based data from the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute, these latest studies look at two cancers in particular: testicular germ cell tumors and glioblastoma.


Brain: Use it so you don't lose it

Washington D.C, Aug 4 : When it comes to warding off Alzheimer's disease, a new research suggests a lifetime of mental activity can be good for you.

Iowa State University researchers identified a protein essential for building memories that appears to predict the progression of memory loss and brain atrophy in Alzheimer's patients.

Research assistant Auriel Willette said that the findings also suggest there is a link between brain activity and the presence of the protein neuronal pentraxin-2, or NPTX2.
