Plants have a double line of defence

...ope to try to identify materials that are built up via PEN2 at the place of infection. They surmise that these materials could lead to the development of new kinds of "green fungicide" with a broad range of effects in the fight against plant diseases. ...

Polymer gel can block toxic leakage problem in gene therapy

...s were being disseminated away from the tumor site via the blood stream, Yuan said. "In the past people wouldn't admit that," he said. "Nobody in the gene therapy field would believe this was happening." The study also pinpointed the routes for the viral escapes. Those particles were escaping from the t...

New neurons take baby steps in the adult brain

...e new neuron receives connections that communicate via another chemical, the critical excitatory messenger glutamate. In the adult brain, glutamate is the most prevalent excitatory chemical, and GABA is a major inhibitory chemical. But it turns out that new neurons are excited by GABA, whether they are ...

Cyberkinetics, Case to develop system to help restore extremity function

...ironment and day-to-day changes in the user's body via a feedback method that can adjust the stimulation so that it accomplishes the desired movement. Some FES systems are currently available to consumers, others are undergoing clinical evaluation, and many are still in development. In the future, neur...

New factor implicated in allergy and asthma attacks

...t may be necessary to deliver them every few hours via an inhaler. Boldogh and Sur suggested that it is now important to develop longer-lived antioxidant. "If we can find an antioxidant with a longer half-life, it could be really very effective in asthma and allergy treatment and also prevention," Boldog...

Smoking damages key regulatory enzyme in the lung

Modifications render carbon nanotubes nontoxic

...hree forms of nanotubes that were rendered soluble via the attachment of the chemical subgroups hydrogen sulfite, sodium sulfite and carboxylic acid. The cytotoxicity of undecorated SWNTs was 200 parts per billion, which compares to the level of 20 parts per billion identified last year for undecorated ...

Research casts doubt on circulating stem cells

...e. The story of a "jack of all trades" circulating via the blood stream throughout the body and repairing, wherever needed, any type of tissue is, unfortunately, a myth. In practice their impact is, at best, minimal. The somatic cells mark genetic traits believe by the body to be no longer needed by sti...

Complex gene interactions account for autism risk

...GABA brain system most likely exerts its influence via complex gene-gene interactions. The current findings, and others that might result from the team's new approach, may ultimately point to methods for early diagnosis of autism, and perhaps new autism therapies, according to the researchers. "Identif...

Scientists and engineers apply nature's design to human problems

Tissue regeneration operates differently than expected

...etal muscle tissue can fuse with adult stem cells, via a mechanism based on the participation of mediators which are generally involved in immune cell activation. Although being unable to transdifferentiate into completely functional muscle cells, they are integrated into the tissue complex by fusing wi...

Nanotechnology to provide portable genetic risk detection

...ic anomaly. The sample is injected into the device via a microfluidic header and the deflection of the cantilevers ?by as little as 0.1 to 0.5 nanometres ?is picked up by a photodetector array based on the reflection of light off the cantilevers from Vertical Cavity Surface Emission Lasers (VCSELs). "We...

Firefly protein lets researchers monitor molecule linked to cancer

"Because pigs are particularly susceptible to Nipah infection, public health officials could use these drugs to protect the animals, pig farmers and first-line responders, like paramedics, ...

Molecular mechanism of feather formation found

...n the cells. The over-expression of Bmp2 signaling via the altered receptors led to ongoing down-regulation of normal Shh expression needed to form the barbs. Harris and colleagues used a similar experiment to test whether Shh could up-regulate its own expression during barb formation, and found that it...
