The first clinical trials of a new type of cancer treatment that releases the “brakes” on immune cells indicate that this approach enhances attacks on tumors while sparing the body’s own tissue.
The results of the phase I clinical trials of cytotoxic T-lymphocyte-associated antigen 4 blockade therapy were published online on April 1, 2003, in the Early Edition of the Proceedings of the National Academy of Sciences. The researchers involved in the study included James Allison, a Howard Hughe
Black holes really are holes – objects without a surface – say Drs Christine Done and Marek Gierlinski in a paper accepted for publication in the Monthly Notices of the Royal Astronomical Society. Having an “event horizon” rather than a surface is the property that makes something a black hole but, by definition, it’s impossible ever to see one directly. However, these new results give direct evidence of the existence of such holes in spacetime.
Drs Done and Gierlinski set out to track
Researchers from Chicago have identified focal neurological deficits as a major group of presenting symptoms among patients with West Nile Virus infection, which became epidemic in the United States in 2002. Focal neurological deficits included visual loss, muscle weakness, paralysis of one half of the body, abnormally slow movement, tremor with rigidity, numbness or tingling and unstable gait. Findings of their study are being presented at the American Academy of Neurology Annual Meeting in Honolul
Most people are familiar with the fact that sensitive instruments known as seismographs can detect earthquakes taking place many hundreds or thousands of miles away. By studying the waves from these tremors, scientists can find out about the conditions deep inside our rocky planet.
In the same way, astronomers are now able to measure millions of sound waves that propagate throughout the Sun, causing it to vibrate or ring like a bell. This technique, known as helioseismology, is the solar eq
New research at the Institute of Food Research shows that two food components recognised for their ability to fight cancer are up to 13 times more powerful when put to work together. The results are published in the latest issue of international journal Carcinogenesis.
The study focuses on genes that play an important role in tumour formation, tumour progression, and the spread of tumour cells. The food components sulforaphane and selenium were found to have an increased impact on these gene
Until now, scientists believed that a single area in the brain generated breathing rhythm, enabling breathing to speed up or slow down to adapt to the body’s activity and position. But UCLA neurobiologists have discovered that two systems in the brain interact to generate breathing rhythm — a finding that may translate into better treatment for sleep apnea and sudden infant death syndrome. The journal Neuron reported the findings in its March 6 issue.
“We originally thought that only one bra
