Computers to be used to find blueprint for new influenza drug

... chemically very similar to part of the protective coating around the cells in our throats that the flu virus first attacks when a person becomes infected. The flu virus would be deceived into attacking the drug, called an inhibitor, instead of the cells. The three-year project will be largely carried out b...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

... seek out a unique protein on the protective outer coating of viruses. HIV researchers have attempted to induce broadly neutralizing antibodies ?long-lived, HIV-specific antibodies that can kill all or most HIV strains ?with a similar vaccine design. Some broadly neutralizing antibodies have been isolated f...

Scientists discuss improved biopesticides for locust control in West Africa

... from sunlight," Agblevor said. "We have developed coating technologies to improve on the environmental persistence of the biopesticide, specifically a lignin coating for the spores, which increases their resistance to ultraviolet radiation." Research at Virginia Tec...

Polymers with copper show promise for implanted sensors

...the big issues," he said. In addition, the polymer coating must be very thin for most biomedical applications...xide that can be stored and released from the thin coating on the sensor surface. The new approach is to make polymers that generate nitric oxide from compoun...

Nano-bumps could help repair clogged blood vessels

...elial cells to quickly attach to stents and form a coating only one cell layer thick, which we call a monolayer," Webster said. "Otherwise, if the metal is not entirely coated, blood cells passing through the repaired artery come into contact with the metal and recognize it as foreign." Findings will be pre...

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

...team solved this problem by applying an insulating coating to the entire probe, except its very tip, so there was minimal electrical contact with the solution. According to Lindsay, the solution is required to make the process work because, without it, the initial insulating property of the molecule prevent...

Structure-building cell signals also may influence learning and memory

...ables endocytosis when it disassembles a molecular coating on storage vesicles, which allows the cell to continue making new vesicles as needed. "This was a new pathway for ephrin," said Yamaguchi. "Ephrin has been intensively studied for many years, with most attention being paid to its maintenance of the c...

Purdue researchers use enzyme to clip 'DNA wires'

... wires. Other researchers have "metalized" DNA by coating it with copper, gold and platinum, but no other researchers have coated DNA and then cut the strands into smaller pieces using a "restriction enzyme," a class of enzyme that causes DNA to fragment, Kinsella said. Because magnetic components are esse...

Nanobacteria in clouds could spread disease, scientists claim

...kramasinghe. "Remnants of a sticky protein (slime) 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 Univer...

Innovative coating could give medical implants a longer life

...University have designed a versatile new two-sided coating that could breathe life into medical implants. Cu...ong period of time. In laboratory studies, the new coating provided effective fouling resistance for more than five months, which Phillip B. Messersmith, assoc...

When it comes to cell entry, being average has its advantages

...ticles slip inside cells without a special protein coating called clathrin. The secret, it seems, is to be average. Mid-sized nanomaterials ?about 27 to 30 nanometers in diameter, or about 1,000 times thinner than a human hair ?are optimal for cellular entry. In a research article to be posted this week in ...

Modified collagen could yield important medical applications

...lso release helpful medications while serving as a coating for surgical tools and implants. "With this process," Yu said, "we can make the collagen that's already found in the human body behave in new ways, including some ways that are not found in nature. Modified collagen can give us great new tool for tr...

Unusual antibiotics show promise against deadly 'superbugs'

Fragment of yellow fever virus may hold key to safer vaccine

...all homed in on one particular part of the protein coating the virus. The epitope is called E-71, signifying its address on the envelope protein. Several other amino acids in another section of the folded protein contributed to the neutralization. Yellow fever virus--and its flavivirus cousins, including de...

New research could help us deliver genes for new bone formation

...of Nottingham are developing scaffolds to act as a coating around the nanoscopic gene delivery systems. The scaffold controls the release of the gene delivery systems to generate the prolonged formation and development of bone tissue. The research teams are using the scaffold technology to develop therapeut...

...ial called 'myelin' that is similar to the plastic coating around electrical wires. Nerve cells also have shorter and more numerous fibres or processes called dendrites with many fine branching processes ?similar to the root system of a tree ?that allow them to 'talk' with neighbouring neurons, often as many...

Discovery of T-cell 'traffic control' boosts new drug promise

...ease in which the body's T cells attack the myelin coating of nerve cells and disrupt their function. Neither Goetzl nor Rosen is involved in the on-going clinical trials of the new drugs and neither has financial ties to the companies that manufacture them. Controlling this process with drugs offers "enorm...
