Stem Cells: Deathly Awakening by Interferon
After injuries with blood loss, the body quickly needs to restore the vital blood volume. This is accomplished by a special group of stem cells in the bone marrow. These hematopoietic stem cells remain dormant throughout their lives and are only awakened to activity in case of injury and loss of blood. Then they immediately start dividing to make up for the loss of blood cells. This has recently been shown by a group of scientists headed by Professor Andreas Trumpp of DKFZ.
Researchers Find New Biomarker for Fatal Prostate Cancer
New research findings out of Wake Forest University School of Medicine and the University of Wisconsin may help provide some direction for men diagnosed with prostate cancer about whether their cancer is likely to be life-threatening.
New Laser for Neurosurgery Allows Greater Precision and Efficiency for Removal of Complex Tumors
Surgeons at Northwestern Memorial Hospital are among the first in the country to use a new micro-laser, which uses light energy in place of a cutting tool to remove complicated brain and spine tumors. The technique offers greater precision and efficiency during surgery, reducing the incision size, surgery time and patient recovery period following surgery.
WFU researchers develop new platinum-based anti-tumor compound
Researchers in the Department of Chemistry at Wake Forest University in collaboration with colleagues at the Wake Forest University Health Sciences Comprehensive Cancer Center have developed a new class of platinum-based anti-tumor drugs that animal studies have shown to be 10 times more effective than current treatments in destroying certain types of lung cancer cells.
Innovative method to starve tumours
The development of cancerous tumours is highly dependent on the nutrients the tumours receive through the blood. The team of Dr. Janusz Rak, of the Research Institute of the McGill University Health Centre (MUHC) at the Montreal Children's Hospital, including Dr. Khalid Al-Nedawi and Brian Meehan, has just discovered a new mechanism that tumours use to stimulate the growth of the blood vessels that feed them. The researchers have also proposed a new way to control this process, which may translate into future therapies. These findings were published this week in the Proceedings of the National Academy of Sciences (PNAS).
