Towards precise classification of cancers based on robust gene functional expression profiles

...mplications minimized by following a healthy diet, getting exercise and taking prescribed medications as directed, according to health experts. The Institute for Medical Research at North Shore-LIJ provided funding for this study. The American Chemical Society is a nonprofit organization, chartered by the ...

Potential treatments for neurofibromatosis

...app and his colleagues hope to prevent tumors from getting larger. Eventually, with continuing treatment, they hope the tumors will shrink or die from lack of blood vessel support. Neurofibromatosis gets its name from neurofibromas, the disfiguring and often painful tumors that grow along nerve coverings an...

Wisconsin researchers identify sleep gene

...p sleep and faster during waking times. One way of getting from the faster to the slower state is by opening ion channels, allowing potassium to flow through them. "Our hypothesis is that if you don't have potassium channels, you won't get slow waves," Cirelli says. "The cell membrane will remain activated,...

Chemists identify immune system mechanism for methamphetamine binges

.... "Right now, there's nothing really effective in getting people off methamphetamine," says Janda, who believes that highly specific methamphetamine antibodies can be made in a laboratory and then used as a clinical treatment for addiction. In theory, antibodies to the drug could be mass produced and admini...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

...ipeline right now. Meanwhile, the requirements are getting longer and longer, and this is a huge dilemma with the recent discussion about Vioxx. That’s created some doubt in the approval procedure. I think we have to come to a reasonable expectation here in terms of the balance between benefits and potential...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...e the thawing process. Using vitrification, we are getting 98 percent survival. For a woman with cancer, these are the only eggs she's ever going to have, so it's important that as many as possible remain viable," says Gary D. Smith, Ph.D., associate professor of obstetrics and gynecology, urology, and molec...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

...me; that is what we're trying to understand. We're getting closer to answering this question." The structure reveals a "pseudoknot" that is required for telomerase activity, at whose core three strands of RNA come together to form a triple helix. All vertebrate animals investigated so far have nearly the id...

Bevacizumab Combined With Chemotherapy Improves Progression-Free Survival for Patients With Advanced Breast Cancer

...e amount of time patients lived without the cancer getting worse). Preliminary results suggest that patients in the study who received bevacizumab in combination with standard chemotherapy consisting of single-agent paclitaxel had a delay in worsening of their cancer by four months, on average, compared to ...

Oldest fossil human protein ever sequenced

...PNAS). "This research opens up the possibility of getting detailed protein information from past human populations, to make inferences about the evolution of human diet and physiology," said Erik Trinkaus, Ph.D., the Mary Tileston Hemenway Professor of Physical Anthropology in Arts & Sciences at Washing...

The circadian clock: Understanding nature's timepiece

... Now, a researcher at the University of Calgary is getting a little bit closer to understanding how it ticks. Dr. Michael Antle, a neuroscientist in the U of C's Department of Psychology, has conclusively shown that the 20,000 cells are organized in a complex network of groups that perform different functio...

Discovery clarifies role of peptide in biological clock

The sugar beet industry moved out of Texas in 1997 after the close of the processing plant at Hereford. But the growing research program within Texas Agricultural Experiment Station's plant...

Butterfly migration could be largest known

...f modern times," Shapiro said. Shapiro said he is getting reports of "billions" of butterflies around Trona, near Death Valley, and in the San Fernando Valley. More waves of butterflies are likely to appear in central California over the next few weeks as the insects take wing. Painted lady butterflies, kn...

Researchers test new therapy for advanced melanoma

...s for treatment, but its major limitation has been getting the gene into the cancer. If electroporation can deliver the gene to these tumors reliably and without serious side effects, melanoma and other cancers would be open to many new treatment possibilities."

Hopkins AIDS experts issue warning about global efforts to provide drug therapies

...e most likely to die. In this system, the patients getting a liver transplant were often the most likely to benefit from it, but not always in greatest medical need of surgery. Due to public pressure, the allocation system was revised to put first the most urgent cases, not those who stood the chance of livi...

UCLA cancer researchers shake loose hidden biomarker

...ch destroys the microtubules. "These patients are getting chemotherapy anyway, and once we move the PSMA to a more accessible area on the prostate cancer cell, we might be able to use antibody-based immunotherapies as well, and they could be administered in the blood," he said. Rajasekaran said PSMA is an ...

New study: Sexually transmitted disease treatment can be effectively administered by sex partners
