Brain Tumors :: Newly identified biomarker detects and regulates spread of brain tumors

Researchers have identified a novel biomarker for brain tumors and have uncovered a potential role the marker may play when the tumor spreads or comes back after treatment. The biomarker, a protein known as “soluble attractin,” is normally absent in the central nervous system and is undetectable in cerebral spinal fluid unless malignant astrocytomas are present in the CNS. This newfound ability to identify biomarkers for malignant astrocytomas means physicians will have a minimally invasive method to track the success of treatments.

Breast Cancer :: Surgical biopsy may reveal cancer in women with rare but benign breast condition

A study at Washington University School of Medicine in St. Louis showed that in women whose initial breast biopsies revealed certain rare, yet benign breast conditions, more extensive follow-up surgical biopsies found cancer up to 25 percent of the time. Most of the cancers were invasive, meaning the tumors had penetrated normal breast tissue and would require treatment.

Memory :: Hopkins researchers discover how brain protein ‘Arc’ might control memory

Researchers at Johns Hopkins have figured out how one particular protein contributes to long-term memory and helps the brain remember things longer than an hour or two. The findings are reported in two papers in the November 9 issue of Neuron.

Ecology :: Cloudy day won’t rain on laser communications

Just as clouds block the sun, they interfere with laser communications systems, but Penn State researchers are using a combination of computational methods to find the silver lining and punch through the clouds.

Neuroscience :: Mysterious ‘neural noise’ actually primes brain for peak performance

Researchers at the University of Rochester may have answered one of neuroscience’s most vexing questions — how can it be that our neurons, which are responsible for our crystal-clear thoughts, seem to fire in utterly random ways?

Cancer :: First report that apoptotic and anti-angiogenic therapies work better together than alone

American researchers have found that giving a combination of imantanib and a drug that induces cell death was better at inhibiting the growth of Ewing’s sarcoma in mice than either therapy on its own, according to research presented at the 18th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Prague on Friday.

Prostate Cancer :: Scientists design a PSA-activated protoxin that kills prostate cancer

Scientists have found a way of using a protein made by prostate cancer to target and kill the cancer cells themselves. In preliminary studies the new therapy affected only the prostate, without causing damage to other healthy tissues, and now it is being tested in a phase I clinical trial, according to research presented at the 18th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Prague on Friday.

Cancer :: Firefighters face increased risk for certain cancers

University of Cincinnati (UC) environmental health researchers have determined that firefighters are significantly more likely to develop four different types of cancer than workers in other fields. Their findings suggest that the protective equipment firefighters have used in the past didn’t do a good job in protecting them against cancer-causing agents they encounter in their profession, the researchers say.

Bladder Cancer :: Children’s exposure to smoking cigarettes linked to bladder cancer – UK

Children and adolescents may be even more susceptible to the harmful effects of tobacco smoke than adults – according to new research into bladder cancer published in next week?s edition of the International Journal of Cancer*.

Schizophrenia :: Studies look at how genes affect antipsychotic drug response – Illinois

Researchers at the University of Illinois at Chicago College of Pharmacy are attempting to discover how genes determine how well an antipsychotic medication works in adults and children and the side effects it will cause.
