Affymetrix Launches New Globin-Reduction Kits and Protocol Developed with PreAnalytiX

...t of PreAnalytiX and QIAGEN. "We continue to see a strong market trend towards the correlation of gene expression profiles of whole blood and tissue samples. With the new GeneChip Globin-Reduction Protocol and associated reagent kits, standardization of the entire pre-analytical and analytical process for w...

Successful Test Of Single Molecule Switch Opens The Door To Biomolecular Electronics

...other electrode, turning it from an insulator to a strong conductor and then back into an insulator again. Given the measured electrical properties of the oligoaniline, Lindsay notes that if the molecule is maintained at its highly conductive state (at low voltage) and then the voltage applied to the molec...

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...permanently and keeping the immune cells young and strong in their fight against infection," said Effros. "These therapies are also easier to develop than gene-therapy drugs." The research was supported by a grant from the National Institute of Allergy and Infectious Diseases and a University of California...

Breakthrough isolating embryo-quality stem cells from blood

...her uses un-focused light. This allows laser beams strong enough to detect stretching to be used without killing the cell. According to Dr Michael Watts, an expert in haematology and stem cells at University College London, there are just 10,000 primitive cells in the average adult's bloodstream. Of those,...

Stealth Worms May Improve Insect Pest Control

...e outside the insect host. Numbering about 150,000 strong or more, these juveniles exit the dead larva, carrying the bacteria, and look for other hosts to begin the cycle again. These juveniles also can survive dry conditions in soils for long periods of time before they infect more insects. This naturally...

Wake Forest scientists find new combination vaccine effective against plague

...s of problems. "These results clearly establish a strong foundation for the future use of flagellin as an adjuvant in humans," Mizel said. He said the research shows that the mice were protected for at least three months after immunization. The work is part of a $9.125 million, five-year research program...

Prescription Drug Patches Gaining Ground, Tackling New Therapies

...s is being driven by several factors ?factors with strong demographic and population trend underpinnings. Technology has also played a major role in prescription patch growth. Advances in synthetic materials and patch design have led to patches that are more esthetically acceptable and that are capable of d...

Fox Chase study shows that weakened T-cell receptor signals change T-cell lineage

...e the signaling strength of the gamma-delta TCR. A strong signal, produced in the presence of a specific binding substance, or ligand, directs immature T cells almost exclusively to the gamma-delta lineage. However, weakening the signal promotes alpha-beta lineage development. "The signal strength determin...

Purdue researchers use enzyme to clip 'DNA wires'

...ocess, possibly because the electrical charges are strong enough to hold the particles firmly in place, but weak enough to enable the enzyme to push them out of the way. "The entire strand of DNA used in this research has been stretched onto silicon oxide surfaces at lengths up to 35 microns, or millionths...

...d and Tabago. This 2000 km gap is believed to be a strong barrier for corals and associated reef organisms." "My idea was to test whether or not wrasses in the genus Halichoeres were genetically different North and South of this barrier. Since all of these species have similar abilities to disperse, I expe...

Rabies spread speeds up

...on rabies could spread, Real and colleagues make a strong case that halting its western march depends on a strategy based on early detection and high-powered intervention programs - a sensible approach for any infectious disease. ### Citation: Russell CA, Smith DL, Childs JE, Real LA (2005) Predictive spa...

Engineers improve plastic's potential for use in implants by linking it to biological material

... T59 clung to the plastic. "They had a moderately strong interaction, which is useful to know," Schmidt said, referring to the need for a stable attachment between polypyrrole and biological molecules that T59 would be used to link to. Schmidt's laboratory intends to study T59 as a linker to other molecul...

They showed that strong epidemics of Ebola have decimated populations of large primates over the past several years in the border regions between Gabon and the Republic of Congo. Human infection appears to occur only in a secondary way, through contact with carcasses of dea...

Chemists synthesize molecule that helps body battle cancers, malaria

...ring that the vaccine is potent enough to elicit a strong immune response," Gin said. "We will continue looking for ways to produce new molecules similar to QS-21A that will enhance the body's natural immune response to eradicate diseases." ...

"As we begin to understand the underlying brain processes, we may discover new methods for manipulating those responses to better help smokers quit." While scientists have thou...

Fungus-farming termites descend from an African rain forest Eve

... Lanka, Thailand and Malaysian Borneo, now provide strong evidence that termite agriculture originated in African rain forest. Their reconstruction of ancestral habitats is based on the habitat of living species and analysis of DNA-based reconstructions of termite relationships. The rain forest origin of f...
