Drug makers chase cancer stem cells





As evidence implicating stem cells in cancer mounts, drug makers are taking notice. GlaxoSmithKline (GSK) in December formed a strategic alliance worth up to $1.4 billion with OncoMed Pharmaceuticals, of Redwood City, California. The deal

gives GSK an option to license four of OncoMed's antibody candidates

developed to target cancer stem cells, one of which is scheduled to

enter clinical trials in June.

Anthrax investigation still yielding findings

Chemical composition of spores doesn't match suspect flask.



The deadly bacterial spores mailed to victims in the US anthrax attacks, scientists say, share a chemical 'fingerprint' that is not found in

bacteria from the flask linked to Bruce Ivins, the biodefence

researcher implicated in the crime.



The Federal Bureau of Investigation (FBI) alleges that Ivins, who committed suicide last July, was the person responsible for…

Nanoparticles guide genes through the bloodstream

Scientists from University of Bonn in Germany have designed a technique that allows them to repair damaged arteries’ tissue. The technique is based on

sending genes and healthy cells through the bloodstream to the place

that needs to be repaired.



Earlier, the “problem” was that it was unknown what quantity of healthy cells to send in order to repair the tissue. Small…

What is nanomedicine

Nanomedicine is a subfield of nanotechnology. It is often defined as the repair, construction and control of human biological systems using devices

built upon nanotechnology standards. Basically, nanomedicine is the

medical application of nanotechnology. Nanostructured materials,

engineered enzymes and many other products of biotechnology will be

very useful in the future. Of course, the full potential…

Promising New Nanotechnology for Spinal Cord...

A spinal cord injury often leads to permanent paralysis and loss of

sensation below the site of the injury because the damaged nerve fibers

can't regenerate. The nerve fibers or axons have the capacity to grow

again, but don’t because they're blocked by scar tissue that develops

around the injury.




Northwestern University researchers have… Continue

New killer virus found in Africa

Scientists have identified a lethal new virus in Africa that causes bleeding like the dreaded Ebola virus.

The so-called "Lujo" virus infected five people in Zambia and South Africa last fall. Four of them died, but a fifth survived, perhaps helped by a

medicine recommended by the scientists.…

MIT Researchers use nanotechnology to repair brain damage and restore vision

Spinal cord injuries, serious stroke and severe traumatic brain injuries affect more than 5 million Americans at a total cost of $65 billion a year in treatment. Is there any hope?



Researchers from MIT and Hong Kong University come to give us hope. The group actually managed to partially restore vision to rodents blinded by damage caused to their brains’ visual system. The secret of success is a tiny biodegradable scaffold invented by MIT bioengineers and neuroscientists. This… Continue

Could A Nanotube-based Drug Prevent Radiation Injury

he Department of Defense has commissioned a nine-month study from Rice University chemists and scientists in the Texas Medical Center to determine whether a new drug based on carbon nanotubes can help prevent people from dying of acute radiation injury following radiation exposure. The new study was commissioned after preliminary tests found the drug was greater than 5,000 times more effective at reducing the effects of acute radiation injury than the most effective drugs currently… Continue

Heat can help chemotherapy work better

Cancer patients whose tumors are targeted with heat treatment as well as chemotherapy are more likely to stay alive and cancer-free for longer than those who receive only chemotherapy, researchers said on Tuesday.



The finding suggests it may be possible to cut the dose of chemotherapy drugs by using heat, although more research is needed to establish this, they said.



German researchers looking at cancers in soft tissues such as muscle, fat and tissue around the joints,… Continue

Next partner events of TINC

We are Media Partner of:

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
