Potential New Pathway Can Overcome Glioblastoma Resistance
1/25/2012
Glioblastoma is the most prevalent and most aggressive malignant brain tumor in humans, and is one of the most resistant to current treatments. Individuals with the disease typically survive around 15 months. Earlier research concentrated on activating the (apoptosis) cell death pathway through therapeutic agents like tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)...
Dutasteride Slows Down Early Stage Prostate Cancer Progression
1/25/2012
A study published Online First in The Lancet has found that a common medication (dutasteride) used to treat enlargement of the prostate, may also reduce the need for treatments that pose risks of incontinence and impotence and delay growth of early-stage prostate cancer...
Risk Of Nerve Damage In Prostate Cancer Surgeries May Be Reduced By Preoperative MRI
1/25/2012
Preoperative MRI helps surgeons make more informed decisions about nerve-sparing procedures in men with prostate cancer, according to a new study published online in the journal Radiology. Excluding skin cancer, prostate cancer is the most common cancer diagnosed in American men, according to the Centers for Disease Control and Prevention...
Possible New Pathway Can Overcome Glioblastoma Resistance
1/25/2012
Glioblastoma, a lethal brain cancer, is one of the most resistant to available therapies and patients typically live approximately 15 months...
Study Of Plant Hormone Could Have Far-Reaching Implications For Cell Biology And Disease Research
1/25/2012
A recent Van Andel Research Institute (VARI) study published in the journal Science investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the development of new drugs for a variety of diseases...
The Quality Of Colonoscopy Reporting And Performance Examined By Study
1/25/2012
Researchers in the Netherlands assessed the quality of colonoscopy reporting in daily clinical practice and evaluated the quality of colonoscopy performance. They found that colonoscopy reporting varied significantly in clinical practice. Colonoscopy performance met the suggested standards, however, considerable variability between endoscopy departments was found...
Cell Death Induced In Colon Cancer Cells By Compounds In Mate Tea
1/25/2012
Could preventing colon cancer be as simple as developing a taste for yerba mate tea? In a recent University of Illinois study, scientists showed that human colon cancer cells die when they are exposed to the approximate number of bioactive compounds present in one cup of this brew, which has long been consumed in South America for its medicinal properties...
New Way Discovered To Image Brain Tumors And Predict Recurrence
1/25/2012
After people with low-grade glioma, a type of brain cancer, undergo neurosurgery to remove the tumors, they face variable odds of survival - depending largely on how rapidly the cancer recurs...
Blood Levels Of Lead May Increase Smokers' Risk For Kidney Cancer
1/25/2012
Higher than normal levels of lead in the blood may signal a risk two times higher than average of developing renal cell carcinoma in smokers, according to medical researchers. "Past studies (in cadavers) have shown that, compared with kidneys from individuals without cancer, kidneys from individuals with cancer have higher lead levels," said Emily B...
How Cells Dispose Of Their Waste
1/25/2012
Defective proteins that are not disposed of by the body can cause diseases such as Alzheimer's or Parkinson's. Scientists at the Max Planck Institute (MPI) of Biochemistry recently succeeded in revealing the structure of the cellular protein degradation machinery (26S proteasome) by combining different methods of structural biology...
