Robotic-assisted prostate surgery offers better cancer control

Posted: 28 Feb 2014 01:06 PM PST

An observational study has found that prostate cancer patients who undergo robotic-assisted prostate surgery have fewer instances of cancer cells at the edge of their surgical specimen and less need for additional cancer treatments like hormone or radiation therapy than patients who have traditional "open" surgery. While the robotic surgery method has higher upfront costs, these may systemically be offset by a reduction of additional cancer therapy costs after surgery due to better cancer control outcomes.

Smoke in the water: Understanding effects of smoke compounds on seed germination

Posted: 28 Feb 2014 11:01 AM PST

Wildfires, although seemingly destructive, play an important role in plant ecosystems. In ecosystems where it occurs regularly, exposure to fire may initiate seed germination or enhance plant growth. Compounds released as plant tissue burns can break seed dormancy and stimulate germination. In a new article, an efficient system to produce smoke solutions is described to aid investigation of the role of smoke compounds in seed germination and seedling growth.

Unexpected findings: 'Promising' drug failed to improve survival in glioblastoma

Posted: 28 Feb 2014 09:14 AM PST

A three-year research project on a deadly form of brain cancer has revealed that a 'promising' drug therapy failed to improve survival among patients with newly diagnosed glioblastoma. "Bevacizuman had been shown in earlier studies to be an effective drug in the treatment of patients with recurrent disease. But, on newly diagnosed patients, it did not, in fact, prolong survival," state the authors.

Psychiatric nursing specialists played key role in response to Boston Marathon bombing

Psychiatric advanced practice nurses (APNs) played a critical role in supporting psychological recovery after the Boston Marathon bombing -- not only for injured patients, but also for family members and hospital staff, according to an article.

Targeting metabolism to develop new prostate cancer treatments

Posted: 27 Feb 2014 04:12 PM PST

The next generation of prostate cancer therapies is targeted at metabolism. A cascade of biochemical reactions inside the cell is being observed and reviewed by scientists, with a focus on an enzyme considered a master regulator of metabolism. By doing so, scientists hope that new research will unlock more effective and less harmful treatments. With approximately one out of six American men being diagnosed and nearly a quarter of a million new cases expected this year, prostate cancer is the most common malignancy among men in the U.S.

Possible new target for future brain cancer drugs

Posted: 27 Feb 2014 01:45 PM PST

A molecule in cells that shuts down the expression of genes might be a promising target for new drugs designed to treat glioblastoma, the most frequent and lethal form of brain cancer. The findings suggest that the protein PRMT5 is a possible prognostic factor and therapeutic target for glioblastoma, and they provide a rationale for developing agents that target PRMT5 in this deadly disease.

Rare disorder causes bleeding on brain of 3-year-old girl

Posted: 27 Feb 2014 01:38 PM PST

A neurosurgeon used a minimally invasive technique to repair an extremely rare blood vessel problem that caused bleeding on the brain of a three-year-old girl. The bleeding on her brain was caused by a complex and potentially devastating condition that is almost never seen in children. There are only a handful of descriptions in the medical literature. The surgery used to treat the girl used an endovascular techniques that use catheters rather than scalpels.
