Proteolytic activity monitored by fluorescence resonance energy transfer through quantum-dot-peptide conjugates

Using a synthetic peptide modeled after the protein that the human immunodeficiency virus (HIV) uses to enter cells, a multi-institutional research team has created quantum dots that can penetrate the cell membrane and image internal structures in a cell.

Imaging pancreatic cancer with a peptide-nanoparticle conjugate targeted to normal pancreas

Most attempts to develop imaging agents that can better distinguish tumors from healthy tissue focus on finding molecules that are more abundant on malignant cells than on normal cells and using those as cellular targets.

Research may pave the way for alternative treatments using cell replacements instead of organ transplants for those with liver failure

University of Edinburgh scientists have identified primitive liver cells -possibly dormant from the earliest developmental stage of a human being - which have the potential to mature into different cells types and help repair a failing liver.

Scientists identify overactive protein that plays a key role in cystic fibrosis

A team led by Johns Hopkins Children's Center scientists has identified and successfully tamed an overactive protein that plays a key role in cystic fibrosis (CF), a genetic disorder that interferes with the body's ability to transport chloride in and out of cells.

Celiac success: New enzyme efficiently degrades gluten

A new enzyme originally developed for commercial food processing turns out to also quickly and nearly-completely break down whole gluten molecules as well as the T cell stimulatory peptides that cause celiac disease, a digestive disease with no current effective treatment other than avoiding wheat, barley or rye products.

Sildenafil boosts high altitude exercise up to 45% for some cyclists

Sildenafil (Viagra) significantly improved the cardiovascular and exercise performance measures of trained cyclists at high altitude, mostly because the drug helped some participants improve a lot -- up to 45% -- while others showed little change. Sildenafil provided no benefit at sea level.
