New IBN Peptides May Help Researchers Combat Alzheimer's, Diabetes and CancerSingapore, Apr 22, 2013 - (ACN Newswire) - Amyloids, or fibrous aggregates of abnormally folded proteins, are a common feature in degenerative diseases such as Alzheimer's, diabetes and cancer. Amyloids occur naturally in the body, but despite decades of research, their mechanism of formation remains unknown, hampering drug development efforts. Now, a new class of ultrasmall peptides developed by the Institute of...

Earlier efforts to determine the health and environmental effects of the nanoparticles that are finding use in hundreds of consumer products may have produced misleading results by embracing traditional toxicology tests that do not take into account the unique properties of bits of material so small that 100,000 could fit in the period at the end of this sentence. That was among the observations presented here today at the 245th National Meeting & Exposition of the American Chemical...

Potential approach to treating atherosclerosis and other chronic inflammatory diseases A multicenter team of researchers, including scientists at Columbia University Medical Center (CUMC), Brigham and Women's Hospital (BWH), Mount Sinai School of Medicine, and Massachusetts Institute of Technology, has developed biodegradable nanoparticles that are capable of delivering inflammation-resolving drugs to sites of tissue injury. The nanoparticles, which were successfully tested in mice, have...

Singapore, Mar 16, 2013 - (ACN Newswire) - The liver is an important target organ for drug testing because all drugs pass through it for detoxification. This is a process whereby harmful substances are reduced or removed from the body. Drugs that cannot be detoxified may cause poisoning or other lethal side effects. IBN researchers have now made it possible for companies to predict the toxicity of new drugs earlier, potentially speeding up the drug development process and reducing the cost of...

Every day scientists learn more about how the world works at the smallest scales. While this knowledge has the potential to help others, it's possible that the same discoveries can also be used in ways that cause widespread harm. A new article in the journal Nanomedicine, born out of a Federal Bureau of Investigation workshop held at the University of Notre Dame in September 2012, tackles this complex "dual-use" aspect of nanotechnology research. "The rapid pace of breakthroughs in...

Rice University researchers show short laser pulses selectively heat gold nanoparticles Plasmonic gold nanoparticles make pinpoint heating on demand possible. Now Rice University researchers have found a way to selectively heat diverse nanoparticles that could advance their use in medicine and industry. Rice scientists led by Dmitri Lapotko and Ekaterina Lukianova-Hleb showed common gold nanoparticles, known since the 19th century as gold colloids, heat up at near-infrared wavelengths...

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...
