Magnetic probe successfully tracks implanted cells in cancer patients

... or prevent its recurrence or stem cells to repair damaged organs, say the researchers. Bulte and a team of Dutch researchers used MRI and a magnetic probe approved by both European and U.S. agencies to locate therapeutic cells injected into eight melanoma patients. "Our results show that the MRI-based t...

Clinical trial to test stem cell approach for children with brain injury

...irst ever with potential to repair a traumatically damaged brain," said James Baumgartner, M.D., associate professor of pediatric neurosurgery and co-principal investigator on the project. As a Phase I clinical trial, the project's first emphasis is to establish the safety of the procedure, with a secondar...

Researchers show how air pollution can cause heart disease

...t until now it was poorly understood how pollution damaged the body's blood vessels. In a well-designed mouse study, where animals breathed air as polluted as the air in New York City, the researchers pinpointed specific mechanisms and showed that air pollution can be particularly damaging when coupled with...

Compound from marine bacteria shows potential as multiple myeloma therapy

...ir proteasome jammed, cells die from the backup of damaged proteins. "Proteasome inhibition is a key therapeutic target and bortezomib (Velcade tm) was the first in a new class of compounds in multiple myeloma. NPI-0052 is a novel proteasome inhibitor with a chemical structure and action that is distinct f...

From one cell, many possible cures

A single cell with the potential to repair damaged heart muscle tissue . . . regenerate injured bone . . . create new cartilage or skin . . . even reverse nerve damage. Human stem cells offer tremendous hope for the development of revolutionary medical treatments for these and a variety of other huma...

Associate Professor Peter Dodd and his team from UQ's School of Molecular and Microbial Sciences has secured a five-year, $1.23 million grant from the United States' biomedical funding arm, the National Institute of Health (NIH) to f...

Scientists show how thinking can harm brain cells

...scribe a new mechanism by which brain cells can be damaged during chronic neurodegenerative diseases. When inflammation occurs in the brain, nerve impulses that are passed between cells during routine activities like learning and memory can become toxic. Instead of triggering the formation of memories, these...

Scientists crack code for motor neuron wiring

The studies suggest that the code -- which involves members of the family of transcription factors encoded by the Hox genes -- could also govern the establishment of other spinal cord circuits. This circuitry includes interneuro...

Liver cancer linked to cellular repair pathway
