Discovery of an HIV inhibitor in human blood points to new drug class

...de are highly stable in human blood plasma and are nontoxic even at exceedingly high concentrations. According to the latest World Health Organization estimates, nearly 40 million people worldwide are living with HIV/AIDS, including more than 2 million children. Close to 4 million people became infected wi...

MIT material stops bleeding in seconds

...und and halts bleeding. Once the injury heals, the nontoxic gel is broken down into molecules that cells can use as building blocks for tissue repair. "We have found a way to stop bleeding, in less than 15 seconds, that could revolutionize bleeding control," said Rutledge Ellis-Behnke, research scientist in...

Researchers attack tumor cells by exploiting dependency on sugar metabolism

...ition of LDH-A activity may represent a relatively nontoxic approach to interfere with tumor growth," explains Dr. Fantin. ...

University of Delaware researchers develop cancer 'nanobomb'

...ecause they are powerful, selective, non-invasive, nontoxic and can incorporate current technology, including microsurgery. An advantage over other carbon nanotube treatments being considered by scientists is that with nanobombs, the carbon nanotubes are destroyed along with the cancer cells. Once the nano...

Modifications render carbon nanotubes nontoxic

...s that nanotubes, like buckyballs, can be rendered nontoxic with minor chemical modifications. The findings come from the first toxicological studies of water-soluble carbon nanotubes. The study, which is available online, will be published in an upcoming issue of the journal Toxicology Letters. The researc...

'Cookbook recipes' would cure disease with nontoxic DNA delivery systems

...molecules have created a "cookbook" for a class of nontoxic DNA delivery systems that will assist doctors and clinicians in the safe and effective delivery of genetic medicine. As reported in the Aug. 9 issue of the Proceedings of the National Academy of Sciences, researchers have now performed a careful, co...

Critical step traced in anthrax infection

...e of Science. An anthrax bacterium secretes three nontoxic proteins that assemble into a toxic complex on the surface of the host cell to set off a chain of events leading to cell toxicity and death. Protective antigen (PA) is one of these proteins, and after binding to the cell, seven copies of it assemble ...

Brain-mapping technique aids understanding of sleep, wakefulness

... in a certain population of neurons. The tracer, a nontoxic fragment of the tetanus toxin, transfers itself from one neuron in retrograde fashion to neurons "upstream" -- those from which the tracer-producing neuron receives signals. Researchers then track the tracer to map the upstream neurons. Dr. Yanagisa...
