Quantum dots help cancer imaging studies

One of the more difficult diagnostic tasks an oncologist faces is determining if cancer has spread to the lymphatic system, particularly when it is necessary to assess lymphatic drainage from two separate drainage basins.

Multivalent effects of RGD peptides obtained by nanoparticle display

While a growing body of literature has shown that nanoparticle targeting can improve drug delivery and tumor imaging, there have been few systematic studies examining the net positive effect of nanoparticle targeting.

Otoferlin, defective in a human deafness form, is essential for exocytosis at the auditory ribbon synapse

By studying a gene earlier linked to deafness in humans, researchers now have new insight into the molecular process by which components of the inner ear send messages to the brain.

Scientists discover how brain turns on system designed to protect nerve cells from toxic "free radicals"

Scientists at Dana-Farber Cancer Institute report they have found how the brain turns on a system designed to protect its nerve cells from toxic "free radicals," a waste product of cell metabolism that has been implicated in some degenerative brain diseases, heart attacks, strokes, cancer, and aging.

PGC-1 alpha implicated in Huntington's disease neurodegeneration

A metabolic disorder underlies the brain effects found in those with Huntington's disease, researchers report in an advance article publishing online October 19, 2006. The article will appear in the November 2006 issue of the journal Cell Metabolism, published by Cell Press.

Gene mutation explains type of brittle bone disease

A newly identified gene mutation helps explain a subset of cases of osteogenesis imperfecta (OI), or brittle bone disease, whose origin had until now remained mysterious.

Flexible interface between DNA ligase and a heterotrimeric sliding clamp supports conformational switching and efficient ligation of DNA

Scientists investigating an important DNA-repair enzyme now have a better picture of the final steps of a process that glues together, or ligates, the ends of DNA strands to restore the double helix.

Important first step towards designing new therapies for shingles

A team of scientists at the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), has identified a human protein that helps varicella-zoster virus, the cause of chickenpox and shingles, spread from cell to cell within the body.

An enzyme that regulates ether lipid signaling pathways in cancer annotated by multidimensional profiling

Using a combination of enzyme activity and metabolite profiling, we determined that this protein-whose function was previously unknown-serves as a key regulator of a lipid signaling network that contributes to cancer," said Benjamin F. Cravatt, a Scripps Research professor and a member of its Skaggs Institute for Chemical Biology who led the study.

Blood clotting protein appears to also play a role in fertility

A protein known to play a role in blood clotting and other cell functions is also critical for proper sperm formation in mice, according to researchers from the University of North Carolina at Chapel Hill School of Medicine.

Eating lots of bread associated with increased risk of renal cell carcinoma

A case-control study of more than 2300 Italians has found a significant association between high bread consumption and renal cell carcinoma. Eating a lot of pasta and rice may also raise the risk, while eating many vegetables may lower the risk.

New treatment option gives hope to victims of head and neck cancers

More than 640,000 people worldwide are diagnosed with head and neck cancer each year, and more than 350,000 die from the disease annually.

FDA approves Taxotere for head and neck cancers

The Food and Drug Administration (FDA) today approved Taxotere (docetaxel) Injection Concentrate for use in combination with cisplatin and fluorouracil prior to radiotherapy for the treatment of patients with inoperable, locally advanced squamous cell carcinoma of the head and neck (SCCHN).

HIV exploits competition among T cells - points to new strategy for AIDS vaccination

A new HIV study shows how competition among the human immune system's T cells allows the virus to escape destruction and eventually develop into full-blown AIDS.

Vaccine that protects mice against 1918 influenza virus developed

Federal scientists have developed a vaccine that protects mice against the killer 1918 influenza virus. They also have created a technique for identifying antibodies that neutralize this virus, a tool that could help contain future pandemic flu strains.
