Hepatitis C virus replication in transfected and serum-infected cultured human fetal hepatocytes

Researchers open the way for improved study of hepatitis C virus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines.

New understanding of the hit-and-run tactics used by infectious bacteria

New research from scientists at the University of Cambridge has the potential to radically change our understanding of how infection spreads around the body and improve the methods used to control it.

Researchers to study use of carbon monoxide in treating disease

Scientists at the University of York have won a grant of £110,000 to investigate potential uses of carbon monoxide in treating disease.

Artificially engineered magnetic nanoparticles for ultra-sensitive molecular imaging

Iron oxide nanoparticles have shown promise as agents for detecting tumors using magnetic resonance imaging (MRI), but such efforts have been limited by the relatively weak magnetic signal generated by these nanoparticles.

Dendrimer-based targeted delivery of an apoptotic sensor in cancer cells

Taking a critical step toward the development of a multifunctional nanoscale anticancer agent that can detect cancer, treat it, and then report on the success or failure of that treatment, investigators at the University of Michigan have developed a nanoscale sensor of cell death.

Discovery of protein complex that plays important role in organ formation, cellular development and cicatrisation processes

Cellular movements are essential in organ formation processes, in cellular development and cicatrisation processes.

Simple diagnostic test detects genetic signs of lung cancer in sputum

DNA coughed up along with phlegm could point to lung cancer, say researchers at the University of Maryland School of Medicine who are developing an inexpensive and non-invasive gene probe to help diagnose early stage lung cancer in current and former smokers.

UK backpackers drinking their way across Australia

The perception that UK backpackers do a lot of drinking while they are travelling across Australia has been supported by new research. Forty per cent reported drinking five or more times a week when in Australia, compared to only just over 20% when they were at home.

Microfluidics gives boost to protein crystallization

Proteins produced by cancer cells are among the common targets for anticancer agents, and thanks to efforts in proteomics and cancer genomics, the number of potential protein targets is increasing exponentially.

Nanoparticles yield delivery tools for therapeutic nucleic acids

Cancer researchers hold great hope that nucleic acid-based therapeutics, such as anticancer genes, antisense oligonucleotides, and small interfering RNA (siRNA) molecules, will prove to be powerful antitumor agents.

Targeting of cancer cells with ferrimagnetic ferritin cage nanoparticles

Researchers at Montana State University have used an engineered form of ferritin, a cage-like iron storage protein, to both synthesize and deliver iron oxide nanoparticles to tumors.

Biomimetic amplification of nanoparticle homing to tumors

A collaborative, multidisciplinary team of researchers has created nanoparticles that act much like a developing clot to target tumors.

Selective marker found to indicate aggressive form of breast cancer

Researchers have linked a structural protein called nestin to a particularly deadly form of breast cancer, identifying a new biomarker that could lead to earlier detection and better treatment.

Fibrinogen molecule structure acts as a molecular spring

Researchers at the University of Pennsylvania School of Medicine and the School of Arts and Sciences have shown that a well-known protein structure acts as a molecular spring, explaining one way that clots may stretch and bend under such physical stresses as blood flow.

Variations in SORL1 gene may factor in development of Alzheimer's disease

Variations in a gene known as SORL1 may be a factor in the development of late onset Alzheimer's disease, an international team of researchers has discovered. The genetic clue, which could lead to a better understanding of one cause of Alzheimer's, is reported in Nature Genetics online, and was supported in part by the National Institutes of Health (NIH).

Stem cell research discovery could mean 'big things' for cancer

A new discovery in stem cell research may mean big things for cancer patients in the future. Gary Van Zant, Ph.D., and a research team at the University of Kentucky published their findings in Nature Genetics.

New approach offers hope for an effective herpes vaccine

A researcher at Montana State University has called for an innovative, new approach in developing a vaccine against genital herpes.

Fat-hormone leptin may enhance the growth of colonic cancers

Tests on three human colon cancer cell lines showed that the fat-hormone 'leptin' may enhance the growth of colonic cancers. This finding could show why obese people are at increased risk of colon cancer.

Cartilage discovery offers arthritis hope

Scientists have revealed the intricate structure of cartilage in what they hope will provide clues to how the crippling joint disease osteoarthritis might one day be treated.

New hope for Krabbe disease sufferers

By all expectations, it shouldn't have worked as well as it did. A combination of bone marrow transplantation and gene therapy greatly lengthened the lives of laboratory mice doomed by a rapidly progressing, fatal neurodegenerative disorder also found in people.
