Brain inflammation may be friend, not foe, for Alzheimer's patients

...sease, but it’s also been fraught with difficulty, producing side effects such as encephalitis or severe brain inflammation in people with Alzheimer’s. “The potential to treat Alzheimer’s disease by modulating the immune system is tremendous and is an area that has not been fully explored,” said O’Banion. “...

Soils offer new hope as carbon sink

... the trials, has a pilot plant at Gosford which is producing minimal amounts for research purposes. "We are hoping the technology will take hold and pyrolysis plants will be built where there is a steady stream of green or other biomass waste providing clean energy that is carbon negative," Dr Van Zwieten s...

A new plant-bacterial symbiotic mechanism promising for crop applications

...nt work, seeking to identify the genes involved in producing the unknown signal molecule that plays the role of Nod factor, prompted the team’s hypothesis that a molecule similar to a plant hormone (4), cytokinin, could act in the mechanisms by triggering nodulation. The discovery of the nature of the signal m...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...alciparum degrades the hemoglobin in the red cell, producing a toxic byproduct known as heme, which the parasite then crystallizes so that it won't be poisoned by it. Eventually, however, an infected person can die from cerebral hemorrhages or anemia that are consequences of red cell infection. Natural pro...

Brightening prospects of using fluorescent nanotubes in medical applications

...semiconducting nanotubes, or SWNTs, are capable of producing light. Metallic nanotubes actually inhibit the brightness of their fluorescent neighbors. But it has been very difficult to separate the strongly fluorescent SWNTs from all the rest in large quantities. Nanotube soot is insoluble in water. So resea...

Could fungal collection hold the key to new life-saving drugs?

...0 strains, including Fleming’s original penicillin producing isolate. They will be supplying the University of Strathclyde’s Institute for Drug Research (SIDR) with extracts from filamentous fungi which will be screened to identify pharmaceutically active compounds, which could potentially be developed into d...

Potent possibilities for parasite attack

...y acid synthase, an enzyme that may be involved in producing components of the cell membrane. CFAS is present in the genomes of L. braziliensis and L. infantum, but is absent from the human genome. The parasite genes are thought to have been acquired from bacterial species that have very similar sequences. ...

Common treatment for methamphetamine overdose may damage brain cells

"This work in laboratory animals raises immediate concerns that a standard treatment for methamphetamine overdos...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...known RNA interference to prevent the insects from producing the phenoloxidase enzyme. These insects were more susceptible to regular Photorhabdus bacteria. But when the two were combined, it was found that not being able to produce ST made no difference to Photorhabdus when colonising insects unable to pro...

Herpes infection may be symbiotic, help beat back some bacteria

...d HHV7 permanently infect most humans without ever producing any significant symptoms. The results have potentially wide-reaching implications for immune research. Humans and other mammals have spent millions of years living and evolving with latent viral infections, Virgin notes, and the new results imply ...

Danish researches solve virus puzzle

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

...e Research Meeting. "Current vaccines are good at producing antibodies that block entry into the cell. In the case of some diseases, such as malaria or tuberculosis, antibody vaccines just aren't effective," says Jenny Wilson-Welder, a lead researcher on the study. Wilson-Welder and her colleagues initial...

UCLA study uncovers clues for why Graves' disease attacks the eyes

...es?disease, the thyroid gland goes into overdrive, producing excess levels of hormone that attack the tissue behind the eye, causing them to protrude. In extreme cases, patients experience trouble closing their eyelids, severe double vision, corneal scarring, optic nerve damage and even blindness. Graves...

A 'traffic light' for neurons means 'go' for improving brain research

..., the researchers used a virus to insert genes for producing light-sensitive proteins into cells of interest. The gene ChR2 is derived from an algae that makes affected neurons more active when exposed to blue light. Deisseroth and collaborators first showed this in a paper in Nature Neuroscience in 2005. In t...

Male-killing bacteria makes female butterflies more promiscuous

...ale partners leads to fatigue in males. They start producing smaller sperm packages. Unfortunately, the female butterflies instinctively know that the packages are smaller and that their chances of having been impregnated after mating are lower than usual. This just makes them more rampant!" The male-killli...
