RNA interference stops colon cancer spread in mice

...it their use. "When we treat with siRNA and then follow the treatment with standard chemotherapeutic agents, we can markedly increase the rate at which cancer cells are killed," Evers said. "Since we have not seen any toxicity with these siRNAs in our mice, we think we can potentially also use them as a w...

Radiation-armed robot rapidly destroys human lung tumors

...kers attached to the patient's chest or abdomen to follow tumors in real time with a few millimeters of accuracy. The researchers also applied Synchrony to treating tumors in the thorax and abdomen, which can move as much as 4 cm during respiration. ...

Production of key Alzheimer's protein monitored for first time in humans

...the effectiveness of a new Alzheimer's drug was to follow the mental performance of patients receiving the treatment over many months or years. "This new test could let us directly monitor patients in clinical trials to see if the drug is really doing what we want it to do in terms of Abeta metabolism," B...

Indonesia - disaster relief aid in action

...tional aid personnel will depend on information to follow via the scouts. The RDRTF has already received a generous offer from Australian colleagues via Dr. David Harris, Westmead, volunteering to provide on-call support. ISN's Team will remain on the ground until further notice. ...

Inflammation and drugs to control this activity studied in a variety of tumors sites

...tially shown chronic prostate inflammation. In the follow up, 29 new cancer cases were diagnosed: six occurred in patients in whom initial biopsies showed only chronic inflammation, 15 in patients with initial PAH/PIA lesions, along with eight in patients with chronic inflammation and other risk factors for...

Scientist warns of threat to last stronghold of endangered turtle

...ellite trackers the team are using the internet to follow their journeys, which are among the longest in the animal kingdom. Dr Brendan Godley, of the University of Exeter, said: "Pacific leatherbacks have been decimated by incidental capture at sea and overexploitation so it's vital that we protect the A...

BioMed Central launches Biology Direct

Biology Direct is led by Editors-in-Chief David J Lipman, Director of the National Center Biotechnology Info...

Evolution follows few of the possible paths to antibiotic resistance

..."Just as there are many alternate routes one might follow in driving from Boston to New York, one intrinsic property of DNA is that very many distinct mutational paths link any two variants of a gene," says lead author Daniel M. Weinreich, a research associate in Harvard's Department of Organismic and Evolu...

Potential heart benefit found in stem cells

...gnificant increase in wall motion at the six-month follow up. The team noted a trend to smaller stress-induced defects, and found that the number of bone-marrow stem cells injected was positively related to the follow-up EF levels, and negatively correlated to the stress-induced and resting perfusion defec...

The giant protein titin helps build muscles

...the scientists think, that some of the connections follow the example of titin and telethonin. The groups will now look for other examples. The terminal assembly complex investigated in this work, though, only covers a tiny part of the giant muscle protein titin, which possesses tens of thousands of amino a...

First demonstration of 'teaching' in non-human animals

... leader finds a naïve individual who is willing to follow her. But tandem runs are rather slow because the follower frequently pauses to look round for landmarks so that it can learn the route. Only when the follower has done this does it tap on the hind legs and abdomen of the leader to let it know that th...

UCLA scientists uncover mechanism of response to targeted therapy

... drug was working. "If we can use PET scanning to follow response, patients won't need repeated invasive tests," Thomas said. "This would save them from getting an added surgical procedure. And we can see, in a very short time, probably in less than a week, whether the drug is working." The study was a co...

Despite the worldwide decline, the number of attacks in the United States rose slightly, from 30 in 200...

Neuroscientists discover new cell type that may help brain maintain memories of smells

...icroscope allowed me to identify the axon and then follow it for long distances without damaging the Blanes cell. Once I could follow the axon as it coursed through the brain, it was relatively easy to see where it ended and where I s...

Chemical guidance of T cells leads to immunologic memory and long-term immunity

...ey express receptors that allow them to detect and follow these chemokines. The NIAID team also showed that when dendritic cells interact in specific fashion with helper T cells, the activated cell pair releases the chemokines CCL3 and CCL4. It is the combination of these two chemokines that the CD8+ T cel...

Study finds evolution doesn't always favor bigger animals

...dy temperatures, such as mollusks to turtles, also follow this rule. "It is a bit of a puzzle why Bergmann's Rule holds in cold-blooded animals like ostracodes," said Hunt. Hunt and Roy found that as ocean temperatures declined by some 10 degrees centigrade, from 40 million years ago to the present day,...
