Breakthrough method in nanoparticle synthesis paves the way for new pharmaceutical and biomedical applications

...lies in the production of pure chiral drugs, which make up over one-third of all pharmaceutical drugs currently sold worldwide. Chiral drugs are comprised of “left-handed?and “right-handed?molecules, both of which are mirror images of each other. Only one of these molecules provides the therapeutic effect...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...cription of all protein-interaction circuits would make such a model possible. "We'd like to simulate diseased cell types, such as cancer cells, and then simulate the effects of drugs on those diseased cells," said Ideker. "Ultimately, we think this kind of a systems biology approach will have a very bene...

South America's vast pantanal wetland may become next everglades, UNU experts warn

...ered by drainage projects starting in the 1940s to make way for development and agriculture. In a message to mark World Water Day, March 22, UNU says the Pantanal provides enormous environmental services by storing and purifying water, providing storm protection and flood mitigation, and stabilizing the ...

World's largest rainforest drying experiment completes first phase

...ess of the sugar and other carbohydrates that they make to wood production. This finding has important implications for climate change since the amount of carbon removed from the atmosphere during tropical droughts will decrease significantly. In addition, there are implications for sustainable forest man...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...n University scientists have "programmed" cells to make their own contrast agents, enabling unprecedented high-resolution, deep-tissue imaging of gene expression. The results, appearing in the April issue of Nature Medicine, hold considerable promise for conducting preclinical studies in the emerging fiel...

In the migratory marathon, parasitized monarchs drop out early

...is so. Explanation : infected monarchs quite don't make it while migrating long distances, so they can't propagate the infection once arrived at destination. A little-studied outcome of animal migration is whether these long journeys can limit the spread of parasites by weeding out diseased animals. Mon...

In April 2005, Affymetrix will make ArrayAssist Lite available to its existing GeneChip customers via the Internet and will also begin pre-installing the software on new GeneChip workstation desktops. Through an easy-to-use interface and tightly integrated workflow, ArrayAssist Lite wi...

PCRM develops world's first cruelty-free insulin assay

..."We have proven that if researchers are willing to make the effort, there are effective, humane alternatives to animal-based assays and other testing procedures--alternatives that could help save the lives of millions of people and animals." There are an estimated 194 million people worldwide with diabet...

Sequencing of marine bacterium will help study of cell communication

The more GC content, the more tightly DNA strands bind.) Despite the fact that it is a symbiont, V. fischer's genome contains genes that may have toxi...

Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss

... of the eye and replaces it with saline. They then make a pinpoint opening in the retina through which they inject fluid to lift up a portion of the retina from the back of the eye, creating a small pocket in the "subretinal space" just wide enough to accommodate the ASR. The surgeons then enlarge the po...

Kinovate Life Sciences Launches Nittophase?High Performance Solid Support For Oligonucleatide Synthesis

In this way we see considerable potential to make it possible for players of all scales in this industry to meet both long and short term objectives of cost savings, and the eventual development of oligonucleotide drugs that are affordable to patients,?stated Dr. Kenji Matsumoto, President of Kinova...
