Painless, portable device could be an alternative to traditional mammograms

Whether a painless, portable device that uses electrical current rather than X-ray to look for breast cancer could be an alternative to traditional mammograms is under study at the Medical College of Georgia.

Pain-relieving gel eases mammography discomfort

The simple application of a pain-relieving gel may reduce the breast discomfort some women experience during mammography exams, according to the results of a clinical trial published in the online edition of Radiology.

Discovery of new anatomical path through which the brain and spleen communicate

In a major step in understanding how the nervous system and the immune system interact, scientists at The Feinstein Institute for Medical Research have identified a new anatomical path through which the brain and the spleen communicate.

First human tests of an injectable vaccine grown in genetically engineered plants

Plants could act as safe, speedy factories for growing antibodies for personalized treatments against a common form of cancer, according to new findings from the Stanford University School of Medicine. The findings came in the first human tests of an injectable vaccine grown in genetically engineered plants.

Gene expression test could help determine who needs more aggressive treatment

Researchers from four leading cancer centers have confirmed that an analysis involving a panel of genes can be used to predict which lung cancer patients will have the worst survival. The finding could one day lead to a test that would help determine who needs more aggressive treatment.

HIV-I damages the immune system early than originally thought

New research into the earliest events occurring immediately upon infection with HIV-I shows that the virus deals a stunning blow to the immune system earlier than was previously understood. According to scientists at Duke University Medical Center, this suggests the window of opportunity for successful intervention may be only a matter of days - not weeks - after transmission, as researchers had previously believed.

Could arthritis wonder drugs provide clues for all disease?

Drugs that have helped treat millions of rheumatoid arthritis sufferers may hold the key to many more medical conditions, including atherosclerosis - a leading cause of heart disease - says the researcher who jointly invented and developed them.

Researchers find better way to distinguish melanoma from some benign moles

University of Rochester Medical Center researchers found a new protein produced excessively in malignant melanoma, a discovery that is particularly relevant as skin cancer rates climb dramatically among young women.

Hormesis deserves the respect and attention of toxicologists

A comprehensive review published in Environmental Toxicology and Chemistry argues that toxicologists can positively affect public health and reduce the economic costs of drug treatment by increasing their knowledge of hormesis and applying its principles to their discipline.

New technology revolutionizing drug discovery

The National Science Foundation has awarded Weill Cornell Medical College researcher Dr. Scott Blanchard its prestigious Career Award, recognizing his groundbreaking work in cell biology -- work that is poised to revolutionize research for the next generation of young scientists.

Quick formula could forecast which cancers chemo could kill

Researchers at the University of Rochester Medical Center have coined a simple formula that predicts how well a certain chemotherapy will work for targeting brain and other nervous system cancers. The formula, which publishes mid-July in Cancer Chemotherapy and Pharmacology, is pegged to two important proteins that compose such hard-to-kill tumors - one of which, ironically, makes them so drug-resistant in the first place.

Researchers step closer to delivering cancer-killing drugs to pediatric brain tumors

An interdisciplinary team of researchers at Washington University in St. Louis, led by Karen L. Wooley, Ph.D., James S. McDonnell Distinguished University Professor in Arts & Sciences, is a step closer to delivering cancer-killing drugs to pediatric brain tumors, similar to the tumor that Senator Ted Kennedy is suffering from.

Researchers locate and image prostate cancer as it spreads to lymph nodes

Using an engineered common cold virus, UCLA researchers delivered a genetic payload to prostate cancer cells that allowed them, using Positron Emission Tomography (PET), to locate the diseased cells as they spread to the lymph nodes, the first place prostate cancer goes before invading other organs.

Compound honokiol, from Magnolias blocks, elusive pathway for cancer growth

A natural compound from magnolia cones blocks a pathway for cancer growth that was previously considered "undruggable," researchers have found.

Treating rare breast cancer with radiation therapy may lower recurrence rate

Patients with a rare type of breast cancer may benefit from receiving radiation therapy in addition to surgery to prevent recurrence, according to a study in the July issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

Prostate cancer vaccines found to be more effective with hormone therapy

Among patients with castration-resistant prostate cancer, the addition of hormone therapy following vaccine treatment improved overall survival compared with either treatment alone or when the vaccine followed hormone treatment, according to recent data published in the July 15 Clinical Cancer Research, a journal of the American Association for Cancer Research.

Nanomaterials key to new strategies for blocking metastasis

A new treatment strategy using targeted nanoparticles to block metastasis with anti-cancer drugs leads to good results using significantly lower doses of toxic chemotherapy, with less collateral damage to surrounding tissue, according to a collaborative team of researchers at the Center of Nanotechnology for Treatment, Understanding, and Monitoring of Cancer at the University of California, San Diego. In designing this system, the investigators, led by David Cheresh, Ph.D., have identified what may become a generic method for using nanotechnology to target metastasis.

Circulating tumor cells can reveal genetic signature of dangerous lung cancers

Using a miniature laboratory-on-a-chip device, a team of investigators at the Massachusetts General Hospital, led by Daniel Haber, M.D., Ph.D., and Mehmet Toner, Ph.D., both members of the MIT-Harvard Center for Cancer Nanotechnology Excellence (CCNE), has developed a method that detects and analyzes the genetic signature of rare tumor cells in the bloodstream.

Nanotechnology, biomolecules, and light unite to "cook" cancer cells

Using carbon nanotubes linked to tumor-homing antibodies, a research team headed by Ellen Vitetta, Ph.D., M.D., of the University of Texas Southwestern Medical Center has shown that they can specifically kill the targeted tumor cells using near-infrared light. This work appears in the Proceedings of the National Academy of Sciences.
