In a world-first, researchers from the Australian Centre for Nanomedicine at the University of New South Wales (UNSW) in Sydney have developed a nanoparticle that could improve the effectiveness of chemotherapy for neuroblastoma by a factor of five. Neuroblastoma is an aggressive childhood cancer that often leaves survivors with lingering health problems due to the high doses of chemotherapy drugs required for treatment. Anything that can potentially reduce these doses is considered an...

Electronic Nose Prototype Can Sniff Out Harmful Substances

April Flowers for redOrbit.com - Your Universe Online No one denies that a sense of smell is important. People have trained themselves to smell the subtle differences in foods and wines and perfumes. We have trained dogs that can smell explosives and drugs and even the changes in a person's body when they are going to have a seizure. With this much emphasis on smelling, is it any wonder that someone has developed an electronic nose? Research by Nosang Myung, a professor at the...

A compound found in green tea could be a weapon in treatments for tackling cancer, according to newly-published research at the University of Strathclyde in Glasgow, Scotland. The extract, known as epigallocatechin gallate, has been known to have preventative anti-cancer properties but fails to reach tumors when delivered by conventional intravenous administration. However, in initial laboratory tests at the Universities of Strathclyde and Glasgow, researchers used an approach which...

Particles that shut off cancer genes could also allow researchers to screen potential drug targets more rapidly By sequencing cancer-cell genomes, scientists have discovered vast numbers of genes that are mutated, deleted or copied in cancer cells. This treasure trove is a boon for researchers seeking new drug targets, but it is nearly impossible to test them all in a timely fashion. To help speed up the process, MIT researchers have developed RNA-delivering nanoparticles that allow for...

Researchers at Brigham and Women's Hospital (BWH) are the first to report a new approach that integrates rational drug design with supramolecular nanochemistry in cancer treatment. Supramolecular chemistry is the development of complex chemical systems using molecular building blocks. The researchers utilized such methods to create nanoparticles that significantly enhanced antitumor activity with decreased toxicity in breast and ovarian cancer models. "This work is effectively moving...

Scientists are reporting an advance toward treating disease with minute capsules containing not drugs – but the DNA and other biological machinery for making the drug. In an article in ACS' journal Nano Letters, they describe engineering micro- and nano-sized capsules that contain the genetically coded instructions, plus the read-out gear and assembly line for protein synthesis that can be switched on with an external signal. Daniel Anderson and colleagues explain that development of...

Trinity College Dublin scientists establish link between autoimmune diseases such as rheumatoid arthritis and nanoparticles New groundbreaking research by scientists at Trinity College Dublin has found that exposure to nanoparticles can have a serious impact on health, linking it to rheumatoid arthritis and the development of other serious autoimmune diseases. The findings that have been recently published in the international journal 'Nanomedicine' have health and safety implications for...

In Switzerland, more than 20,000 people (37% of all deaths) die of cardiovascular disease caused by atherosclerosis each year. Treatment options are currently available to people who suffer from the disease but no drug can target solely the diseased areas, often leading to generalized side effects. Intravenous injection of a vasodilator (a substance that dilates blood vessels), such as nitroglycerin, dilates both the diseased vessels and the rest of our arteries. Blood pressure can thus drop,...

A new generation of cancer treatments based on nanotechnology is making its way out of the laboratory and into the clinic with the promise of targeting cancer cells while steering clear of healthy tissue, according to the current edition of Chemical & Engineering News (C&EN). C&EN is the weekly news magazine of the American Chemical Society (ACS), the world's largest scientific society. In the cover story, C&EN Senior Editor Bethany Halford explains that today's anti-cancer...

Pared-down nucleic acid nanoparticle poses less risk of side effects, offers better targeting. Using a technique known as “nucleic acid origami,” chemical engineers have built tiny particles made out of DNA and RNA that can deliver snippets of RNA directly to tumors, turning off genes expressed in cancer cells. To achieve this type of gene shutdown, known as RNA interference, many researchers have tried – with some success – to deliver RNA with particles made...
