'Nano-keys' bind cell receptors and trigger allergic reactions

... However, nanotechnology now gives researchers new tools to understand the role of cell membranes in activating responses within cells. Barbara Baird, Cornell professor of chemistry and chemical biology, reported this research today (Feb.16) at the annual meeting of the American Association for the Advanc...

Gene patterns in white blood cells quickly diagnose disease

...ours after exposure. Use of mathematical modeling tools has identified a list of over 300 genes that can discriminate among 8 pathogenic agents with 99 percent accuracy," says Hammamieh. They are also looking for gene expression patterns that could help determine severity of exposure While the technolo...

Researchers solve mystery of how nuclear pores duplicate before cell division

...nuclear membrane. Using advanced real-time imaging tools the scientists watched as a nuclear membrane ?pores and all ?formed within an hour. "We were able to visualize single nuclear pore complexes," says graduate student and co-first author Daniel Anderson. "This allowed us not only to watch as single p...

Earth Rx: A microbial biotechnology prescription for global environmental health

...unities, the first use of modern molecular biology tools began in the early 1980s, with the advent of polymerase chain reaction (PCR) amplification of microbial DNA and a new view of the evolution of organisms based on their ribosomal RNA. These technologies have advanced into high-throughput genomic and ...

Sea coral's trick helps scientists tag proteins

...e fluorescent proteins (PAFPs), innovative imaging tools first made possible by Douglas Prasher, who isolated the gene for green fluorescent protein (GFP) from a species of bioluminescent jellyfish in 1992, and Martin Chalfie, who first used GFP for labeling in 1994, said Marc Zimmer, a computational chemi...

Oh, rats! Designer animals reveal possible heart disease genes

...salt diets, while others stay healthy? To turn the tools of genomics onto these questions, the National Heart, Lung, and Blood Institute, part of the National Institutes of Health, funded the new study. In the first part of the study, MCW researchers began with a strain of rats bearing high blood pressure...

Illinois pig to make history as source of first complete swine genome

...tensive swine research, the development of genetic tools and a campus commitment to pursue genome-related r...s extracted, donated and cloned to develop genetic tools and biomedical models. The USDA grant -- issued through its National Research Initiative -- also re...

Report finds cruise industry is protecting the precious places it visits

...ts: Governments should examine creative financing tools such as trust funds, or concession agreements that provide revenue and establish better management practices; charge entrance fees to protected areas and ensure that the revenues from those fees go back into the management of those sites; and develop...

Two NIH initiatives launch intensive efforts to find roots of common diseases

St. Jude projects 90 percent cure rate for ALL

...doses of those agents," Evans said. "By having the tools to precisely assess the risk of relapse in a specific patient, we can design the most effective treatments possible at the start of therapy. That's a key element of our success in raising the cure rate for ALL while limiting toxic effects of therapy....

Virginia Bioinformatics Institutes launches microbial database

... of these pathogens as well as powerful analytical tools widely available to researchers in one integrated resource. The work described in the paper was completed by Brett Tyler, VBI research professor and professor of plant pathology, physiology, and weed science at Virginia Tech, and VBI researchers Such...

Fruit fly reveals a potential connection between dementia and cancer

... human disease, lies in the ability to use genetic tools to establish a causal connection between a molecular pathway and neuronal death. Khurana and colleagues found that, as in human disease, abnormal expression of cell-cycle proteins accompanied neuronal death in their fly model. Most importantly, loss ...

World Trade Center identifications pushed forensic DNA technology

...cable to forensic investigations. "We lacked the tools needed to do the job properly or efficiently," Shaler said in his recent book, "Who They Were: Inside the World Trade Center DNA story: The Unprecedented Effort to Identify the Missing," (Free Press 2005). He adds the staff had "No bar-coding capab...

Aging cells, aging body: Fresh evidence for a connection

...tched the surface. Now that we've come up with the tools and methods for further TIF research, I am eager to see if the same patterns play out in other tissue." Brown post-doctoral research fellow Utz Herbig is the lead author of the article. Brown undergraduate Mark Ferreira rounds out the Brown research...

UCR researchers design chip that can improve citrus varieties

...itrus array will be used to develop new diagnostic tools for the improvement of citrus agriculture and post-harvest fruit handling, as well as to understand mechanisms underlying citrus diseases. Researchers will study traits pertinent to the citrus industry such as easy peeling, seedlessness, flavor compo...

New crop of technology reveals plant health

...ves was to develop the necessary software modules, tools and methodologies that enable the efficient and flexible integration of 'augmented' plants and artefacts into ubiquitous computing applications which may range from domestic plant care to precision agriculture. "The main idea behind PLANTS is to dev...

Mystery solved: Gold's power against autoimmune diseases defined
