Breakthrough developments in rheumatoid arthritis reported

...een able to show that certain markers are strongly linked to certain ethnic groups and others are not. “This will help us in figuring out what exactly is going on in this illness,” he said. “It’s pretty exciting.” Early on in the rheumatoid arthritis research game, when HLA popped out as a major geneti...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...e" light. The finding, the thirteenth gene to be linked to Leber’s congenital amaurosis (LCA), comes at a time of hope for the people born with the disorder. Scientists at Moorfields Eye Hospital, London, recently announced the start of clinical trials for a gene therapy involving injecting genes into the...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

... through the blood were changing in ways that were linked to testosterone levels. Birds who were given additional testosterone depleted their carotenoid levels and became healthier, as if they were combating testosterone directly with antioxidants. “These findings show that there are nutrient specific me...

Genetic factors are linked to fever following smallpox vaccination

...hors analyzed 19 gene clusters (called haplotypes) linked to the body’s response to viral infections. The new study identified a total of eight haplotypes in four different genes that were associated with altered susceptibility to fever after vaccination. It is the first study to show that fever after sm...

Small, self-controlled planes combine plant pathology and engineering

...ege of Agriculture and Life Sciences, has not only linked agriculture and engineering with his interdisciplinary research but has also given scientists an unprecedented glimpse into the life of microorganisms hundreds of meters above the surface of the earth. “Until recently, researchers used autonomous ...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...ached nanoparticles to the outside of bacteria and linked DNA to the nanoparticles. Then the nanoparticle-laden bacteria transported the DNA to the nuclei of cells, causing the cells to produce a fluorescent protein that glowed green. The same method could be used to deliver drugs, genes or other cargo into...

Herpes virus hijacks DNA repair process

.... To ensure that enhanced viral replication wasn't linked to orf36's interactions with other molecules, researchers turned to mice lacking the genes for ATM and H2AX, the damage response proteins activated by infection. When they infected cells from these mice with murine herpes virus, its ability to reprod...

Blood-brain barrier breached by new therapeutic strategy

...0 percent of the mice that got the antiviral siRNA linked to the rabies peptide survived. These experiments demonstrate how the rabies peptide can be used to deliver antiviral siRNA across the blood-brain barrier and into nerve cells in the brain. Once inside brain nerve cells, the antiviral siRNA can silen...

Reconstructing the biology of extinct species: A new approach

...s through the environment -- should be irrevocably linked to the type of locomotion produced by its limbs. "If an animal evolves a new way of moving about the world, its organ of balance must evolve accordingly," Walker explains. From the visual information, the animal tracks its position relative to stat...

Researchers identify protein pathway involved in Parkinson disease development

...ondrial damage. Other scientists recently have linked early onset Parkinson disease to mutations in both copies of the PINK1 gene (one from each parent). They also have evidence that single-copy mutations in PINK1 are a significant risk factor for the development of later-onset Parkinson disease. "W...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

... species, they are really very different organisms linked simply because they have the deadly toxin. For each type, there is also a near-identical but harmless relative that lacks the toxin. C. sporogenes is the non-malignant, near twin of the organism sequenced. Professor Mike Peck, from the Institute o...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

The ecology of picoeukaryotes, said Moreau, has thus become an intense field of investigation over the last decade as these microalgae, although representing a ...

Mice with a migraine show signs of brain damage

...at CSD underlies some migraines, Nedergaard’s team linked the phenomenon for the first time to both severe hypoxia and to damage to brain cells. As a result of CSD, the team found changes to the synapses, the connections between brain cells known as neurons. The team observed that nerve cells swell and begi...
