Discovery of Repair Process After Heart Attack Suggests Potential for New Treatment Strategy

Press_release_Rev.JPG

UCLA stem cell researcher Dr. Arjun Deb has discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells (the cells that form blood vessels), and this study can point the way toward a new strategy for treating patients after a heart attack.

Drexel Study Questions 21-Day Quarantine For Ebola

As medical personnel and public health officials are responding to the first reported cases of Ebola Virus in the United States, many of the safety and treatment procedures for treating the virus and preventing its spread are being reexamined. One of the tenets for minimizing the risk of spreading the disease has been a 21-day quarantine period for individuals who might have been exposed to the virus. But a new study by Charles Haas, PhD, a professor in Drexel’s College of Engineering, suggests that 21 days might not be enough to completely prevent spread of the virus.

Sonic Hedgehog Protein Causes DNA Damage and the Development of Child Brain Tumours

CharronCoverImage.jpg

Scientists at the IRCM and the University of Montreal discovered a mechanism that promotes the progression of medulloblastoma, the most common brain tumour found in children. The team, led by Frédéric Charron, PhD, found that a protein known as Sonic Hedgehog induces DNA damage, which causes the cancer to develop.

Bio-Inspired ‘Nano-Cocoons’ Offer Targeted Drug Delivery Against Cancer Cells

GuCocoonHeaderFULL.jpg

Biomedical engineering researchers have developed a drug delivery system consisting of nanoscale “cocoons” made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs.

Study Finds Link Between Neural Stem Cell Overgrowth and Autism-Like Behavior in Mice

A UCLA study shows how, in pregnant mice, inflammation, a first line defense of the immune system, can trigger an excessive division of neural stem cells that can cause “overgrowth” in the offspring’s brain, and, ultimately, autistic behavior.
