Hepatitis C virus can block other hepatitis C variants from infecting the same cell

There's infection and then there's superinfection - when a cell already infected by a virus gets a second viral infection. But some viruses don't like to share their cells.

Intelligent materials substitute for bone tissue

More than half a million people in the European Union and a million in the United States suffer from disorders in or serious defects of some part of their bone structure.

Key protein - claudin-1- for hepatitis C virus entry identified

For as many as 200 million people worldwide infected with hepatitis C, a leading cause of chronic liver disease, treatment options are only partially effective. But new research by Rockefeller University scientists points to a potential new target for better drugs: a key protein that resides in human liver cells that hepatitis C requires for entry.

Cruelty-free ELISA for human insulin

In the January issue of Clinical Biochemistry, scientists and physicians with the Physicians Committee for Responsible Medicine (PCRM) outline the method used to develop a cruelty-free ELISA for human insulin that uses monoclonal antibodies produced by cells cultured in an animal-serum-free medium.

DNA-based computer that could lead to faster West Nile virus detection

New technique detects signature of metastasizing melanoma with as few as 10 cancer cells present in blood sample.

FDA issues guidance for development of cell-based viral vaccines

The U.S. Food and Drug Administration (FDA) has issued new guidance to aid manufacturers in developing safe and effective cell-based viral vaccines.

p120 catenin protein can stop metastasis or promote it

A protein known to be a key component of the glue that holds cells together also is involved in breaking them apart and promoting their movement when tumors begin to spread to other parts of the body, researchers at Mayo Clinic have found.

New screening method shows how nanoparticles interact with human cells

Scientists at the Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. Using this new method, the investigators have been able to visualize how human cells interact with some specific types of carbon nanoparticles.

Juice lowers Alzheimer's risk

In a large epidemiological study, researchers found that people who drank three or more servings of fruit and vegetable juices per week had a 76 percent lower risk of developing Alzheimer's disease than those who drank juice less than once per week.

New methods for screening nanoparticles and interaction with human cells

Scientists have developed a screening method to examine how newly made nanoparticles - particles with dimensions on the order of billionths of a meter - interact with human cells following exposure for various times and doses.

Birch bark compound may be potent prostate cancer fighter

A compound found in the bark of the white birch tree - betulonic acid, a derivative of betulinol - may finally have been rendered a water-soluble, bio-available drug, and is already showing the potential to be a possible agent against prostate cancer - in cell culture and in an animal model.

Human hair follicles found to be a new source of adult stem cells

Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types.

Differential effects of HOXB4 on nonhuman primate short and long-term repopulating cells

Transplantation of hematopoietic stem cells (HSCs, the cells that can give rise to all blood and most immune cell types) can save patients whose own hematopoietic system is defective or has been destroyed (often through radiation or chemotherapy of cancer).
