Plasma skin regeneration tool may help to reduce wrinkles

A study involving eight patients suggests that multiple low-energy treatments with a plasma skin regeneration tool may help to reduce wrinkles and improve facial appearance with minimal healing time, according to an article in the February issue of Archives of Dermatology.

Targeting bladder tumor cells in vivo and in the urine with a peptide identified by phage display

Efforts to create nanoparticles that deliver anticancer drugs or imaging agents to tumors while avoiding healthy cells are often stymied by a lack of known tumor targets, that is, molecules found on the surface of malignant cells but not healthy cells.

Scientists find connection between nerve cells and immune system

A direct connection exists between the brain and the immune system – at least in mice. Scientists at the Helmholtz Centre for Infection Research in Braunschweig conducted a comprehensive study of mice intestine and the surrounding blood and lymph vessels using special microscopy and marking techniques.

Scientists tackle huntingtin protein

McMaster scientists are very close to defining small molecule drugs that should be able to redirect the huntingtin protein from accumulating in the wrong place within brain cells, which could potentially translate to a therapy for Huntington's Disease (HD).

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.

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.
