Modified bone drug kills malaria parasite in mice

February 28, 2012 5:31 am | News | Comments

A chemically altered osteoporosis drug may be useful in fighting malaria, researchers report in a new study. Unlike similar compounds tested against many other parasitic protozoa, the drug readily crosses into the red blood cells of malaria-infected mice and kills the malaria parasite. The drug works at very low concentrations with no observed toxicity to the mouse.

New molecule discovered in fight against allergy

Lab-made tissue picks up the slack of Petri dishes

January 12, 2012 5:56 am | News | Comments

New research demonstrates that previous models used to examine cancer may not be complex enough to accurately mimic the true cancer environment. Using oral cancer cells in a 3D model of lab-made tissue that mimics the lining of the oral cavity, the researchers found that the tissue surrounding cancer cells can epigenetically mediate, or temporarily trigger, the expression or suppression of a cell adhesion protein associated with the progression of cancer.

December 13, 2011 7:25 am | Product Releases | Comments

JM ?Science’s AQV-2200S AQUACOUNTER Karl Fischer Volumetric Titrator features small volume titration cells requiring only 20 mL of titration solvent for accurate measurements. The instrument is suitable for a wide measurement range from 100 ppm to 100% water content.

Survey reveals scientists have trouble accessing stem cell lines

December 12, 2011 9:39 am | News | Comments

The promise of stem cell research for drug discovery and cell-based therapies depends on the ability of scientists to acquire stem cell lines for their research. A survey of more than 200 human embryonic stem cell researchers in the United States found that nearly four in ten researchers have faced excessive delay in acquiring a human embryonic stem cell line and that more than one-quarter were unable to acquire a line they wanted to study.

Biologists deliver neutralizing antibodies that protect against HIV

December 1, 2011 3:07 am | News | Comments

Over the past year, researchers at the California Institute of Technology (Caltech), and around the world, have been studying a group of potent antibodies that have the ability to neutralize HIV in the laboratory; their hope is that they may learn how to create a vaccine that makes antibodies with similar properties. Now, biologists at Caltech have taken one step closer to that goal: They have developed a way to deliver these antibodies to mice and, in so doing, have effectively protected them from HIV infection.

New compound defeats drug-resistant bacteria

November 29, 2011 5:30 am | News | Comments

Chemists at Brown University have synthesized a new compound that makes drug-resistant bacteria susceptible again to antibiotics. The compound—BU-005—blocks pumps that a bacterium employs to expel an antibacterial agent called chloramphenicol. The team used a new and highly efficient method for the synthesis of BU-005 and other C-capped dipeptides.
