DNA Molecules Used To Assemble Nanoparticles

...Michigan researchers have developed a faster, more efficient way to produce a wide variety of nanoparticle drug delivery systems, using DNA molecules to bind the particles together. Nanometer-scaled dendrimers can be assembled in many configurations by using attached lengths of single-stranded DNA molecules, ...

Tiny particles could solve billion-dollar problem

...e scheme because only a nanoscale catalyst will be efficient enough to provide the throughput needed to make the whole approach effective. Tests in Wong's lab have found that the gold-palladium nano-catalysts break TCE down about 100 times faster than bulk palladium catalysts. ...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

... synthesis of geneseconomical, we can provide more efficient tools to aid the efforts ofresearchers to understand the molecular mechanisms that regulatebiological systems. There are many potential biochemical and biomedicalapplications.?Most immediately, examples include understanding the regulation of genefun...

Learning to fight an adversary that won't stay down

...g we can throw at them. Innovations such as highly efficient polymerase chain reaction (PCR) have made it possible to identify and study the many genes responsible for antibiotic resistance in hospitals and the environment. "What has been found is that there are more antibiotic resistance genes around than we...

Novel Enzyme Shows Potential As An Anti-HIV Target

... produced or existing Tats are deacetylated. Thus, efficient viral replication depends on adequate Tat supplies. And since HIV gene expression relies on SIRT1’s enzymatic activity, inhibiting SIRT1 could prove to be a promising anti-HIV therapy. Future study will have to verify whether inhibiting SIRT1 can suc...

Spider Venom Could Yield Eco-Friendly Insecticides

...ecific neurotoxins focuses on one the world's most efficient insect predators -- spiders. The Blue Mountains fu...ood reason to look for a safer, nontoxic, and more efficient pesticide. More than a billion pounds of pesticides are sprayed in the U.S. every year. That's four ...

Circles Of DNA Might Help Predict Success Of Stem Cell Transplantation

...t is that the patient's thymus gland can act as an efficient factory where stem cells become T cells. The thymus is an immune system organ behind the breastbone that processes immature "precursor" immune cells into specialized T cells. T lymphocytes are specialized immune cells carrying proteins called recept...

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

...r centrifuging processes. This allows for the more efficient synthesis of a wide variety of pharmaceuticals. This improvement in the drug manufacturing process can potentially lead to greater cost savings, as the production of the chiral ingredient currently accounts for 10-40% of the total cost. IBN’s invent...

Genrate: a generative model that finds and scores new genes and exons in genomic microarray data

...ata set, so that good solutions are found using an efficient algorithm. We apply GenRate to a subset of mouse genome-wide expression data that we have created, and discuss the statistical significance of the genes found by GenRate. Three of the highest-ranking gene structures found by GenRate, each containing ...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

... using the Indian mustard plant because it is very efficient at absorbing selenate, the bioavailable form of selenium in the soil. The plant is tricked into absorbing selenate because it is chemically similar to sulfate, an essential nutrient for the plant. Gary S. Banuelos, a soil scientist with the USDA's A...

Findings have implications for tracking disease, drugs at the molecular level

... absorption induced luminescence (MAIL). The most efficient gold nanoparticles could be observed at laser intensities lower than those commonly used for multiphoton imaging, in which specific tissues or cells -- cancer cells, for example -- are fluorescently-labeled using special stains that enable them to be...

Building a protein name dictionary from full text: a machine learning term extraction approach

...iological entity names. It is also computationally efficient and robust to noise commonly found in full text material. We use the method to create a protein name dictionary from a set of 80,528 full text articles. Only 8.3% of the names in this dictionary match SwissProt description lines. We assess the qualit...

Insects, viruses could hold key for better human teamwork in disasters

...behavior also will help in the development of more efficient and effective ways of coordinating knowledge. "Although human social systems are far more complex than insect societies, where a reduced set of rules govern the behavior of each insect for a given situation and the group's behavior emerges from such...

Nanobacteria in clouds could spread disease, scientists claim

...) coating nanobacteria makes them act as extremely efficient cloud condensation nuclei, with a tendency to aggregate to clusters upon contact." Their work corroborates the findings of Ruprecht Jaenicke, of the Institute for Atmospheric Physics at Mainz University, Germany, on bioaerosols (airborne contaminant...

'EuroVacc 02' HIV Vaccine Trial Begins

...y the best candidates for the "prime" and the most efficient for the "boost", results from recent pre-clinical studies in non-human primates conducted by EuroVacc suggest that the use of the DNA as prime followed by a boost based on poxvirus (NYVAC in this trial) induces stronger immune responses than either v...

Scientists find viruses can't stick to sea bugs in the dark

...ealth of the seas, but may also eventually lead to efficient methods of controlling cyanobacteria blooms in an environmentally friendly way, by using these natural viruses. ...

Whole genome promoter mapping - Human Genome Project v2.0?

...rch (LICR) and NimbleGen Systems have developed an efficient method to identify thousands of regulatory sequences in the human genome, according to a study published today in Nature. Genes are defined by their ability to generate a functional product. Thus the 'promoter' - a DNA sequence that controls when an...

...ventive and therapeutic services would be far more efficient than parallel delivery of each intervention separately. "The focus is on community-based resources, which decrease costs since building hospitals and other fixed resources isn't necessary. It is our hope that policymakers, donors and governments wil...

Gene silencing technique offers new strategy for treating, curing disease

...e ground. While that's certainly possible, a more efficient way to staunch the streams of water would be to turn off the faucet. By targeting the chromosomal DNA directly, that's just what Dr. Corey and his colleagues accomplished. The researchers targeted chromosomal DNA in two ways. First, they developed a...
