Unique tomatoes tops in disease-fighting antioxidants

...omato varieties. Cis-lycopene levels spiked around five hours after eating the tangerine tomato sauce, and at this point during absorption the levels were some 200 times greater than those of trans-lycopene, which were nearly non-existent. While cis-lycopene is by far the most abundant isomer in these tom...

New fMRI technology making brain tumor surgery safer

...er than traditional MRI. The DTI scan, which takes five minutes, is performed in the same setting. Dr. Leach processes those images, highlighting the location of speech and movement areas and white matter tracts. He also highlights the tumor location, then imports all of the information into BrainLAB’s...

Salmonella survives better in stomach due to altered DNA

...erovar Typhimurium DT104, is resistant to at least five different antibiotics. Dutch researcher Armand Hermans found new genetic information in DNA of DT104 that might be involved in its survival and infection mechanism. This genetic information might also be involved in the increase in the number of infe...

Researchers show that veins stiffen as we age

... that amazing living pump--your heart--sends about five quarts of blood through the 60,000-mile network of arteries, capillaries and veins in your body. The muscular arteries carry blood away from the heart and out to your organs and limbs. Microscopic capillaries connect the arteries to the veins. The ve...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

...percent were free from recurrence of heart disease five years later. Their quality of life was measured as being at nearly normal. Dr Emma Birks, from the Heart Science Centre at Imperial and the Royal Brompton and Harefield NHS Trust, and lead author of the study, said: "Donor heart transplant has for...

Monoclonal antibody reduces exacerbations in asthmatics

...it is especially useful in patients older than age five who have persistent moderate to severe asthma.) "None of the exacerbations we saw in our study warranted treatment with oral corticosteroids or hospitalization, so they cannot be considered to have been severe," said Dr. Hansel. The researchers not...

Proteins may predict lung transplant rejection

...mortality rate of organ recipients, about 45% over five years, said lead investigator and pulmonologist Chris Wendt. Currently, there is no reliable way to predict which transplants will fail, and when signs of chronic rejection appear, it is usually too late to reverse it, she said. If doctors can predic...

New study aims to stop sepsis in its tracks

... with a grant totaling more than $8.4 million over five years. Derek C. Angus, M.D., M.P.H., of the University of Pittsburgh School of Medicine, leads the consortium, which is a partnership between physicians in emergency medicine and those in critical care medicine. "By improving the treatment of those...

Penn researcher shows that DNA gets kinky easily at the nanoscale

...equired to make various bends in DNA at lengths of five to 50 nanometers --- about a thousand times smaller than the diameter of a typical human cell. ''We found that DNA has different apparent properties when probed at short lengths than the entire molecule does when taken as a whole," Nelson said. ''I...

Unique gene regulation gives chilly bugs survival advantage at bottom of the world

However, the larval midges lived up to four days at the higher temperature ?four times longer than the adults. "The adults were cons...

Men with prostate cancer avoid radiation due to misconceptions

Many men with prostate cancer choose external beam radiation over other treatments because it is non-invasive, has a short recovery period and often helps men preserve their sexual and urinary function. However, Dr....

Triple threat: World fin trade may harvest up to 73 million sharks per year
