Vascular Targeting Agent Halts Bone Metastasis

Vascular Targeting Agent Halts Bone Metastasis
A novel vascular targeting agent completely prevented the development of bone tumors in 50 percent of the mice tested in a preclinical study, providing early evidence that it could treat, or thwart, growth of tumors in bone, a common destination for many cancers when they start to spread.

Scientists at The University of Texas M. D. Anderson Cancer Center published in the journal Cancer Research that this "Trojan Horse" agent, VEGF121/rGel,........Go to the Cancer-blog (Added on 11/15/2006 4:51:41 AM)

Nanoparticles To Target Brain Cancer

Nanoparticles To Target Brain Cancer
Tiny particles one-billionth of a meter in size can be loaded with high concentrations of drugs designed to kill brain cancer. What's more, these nanoparticles can be used to image and track tumors as well as destroy them, as per scientists at the University of Michigan Comprehensive Cancer Center.

Scientists incorporated a drug called Photofrin along with iron oxide into nanoparticles that would target malignant brain tumors. Photofrin is a........Go to the Cancer-blog (Added on 11/15/2006 4:42:45 AM)

Vaccine Against Colorectal Cancer

Vaccine Against Colorectal Cancer
British scientists have developed a vaccine that stimulates colorectal cancer patients' immune systems to fight malignant cells.

In a clinical trial of 67 patients, scientists at the University of Nottingham found that when the vaccines were administered before and after surgery to remove malignant tumors, they helped stimulated immune cell production in up to 70 percent of patients.

Sibling relationships reflect family dynamics

Sibling relationships reflect family dynamics
Most children in the United States grow up with sisters and brothers. Connections that commonly last a lifetime, these relationships can be strained at times, particularly during childhood. New research concludes that sibling ties are best understood in the context of their families, and that efforts to improve relationships should take into account not just the siblings, but the family as a whole.

This research also observed that, overall,........Go to the Psychology news blog (Added on 11/14/2006 4:53:48 AM)

Where Chimp And Human Brains Diverge

Where Chimp And Human Brains Diverge
Six million years ago, chimpanzees and humans diverged from a common ancestor and evolved into unique species. Now UCLA researchers have identified a new way to pinpoint the genes that separate us from our closest living relative and make us uniquely human. The Proceedings of the National Academy of Sciences reports the study in its Nov. 13 online edition.
