Study sheds light on underlying neural mechanism behind macular degeneration

October 20, 2019

Previously, researchers discovered that the deprived neurons begin responding to visual input from another spot on the retina - evidence of plasticity in the adult cortex. Just how such plasticity occurred was unknown, but a new MIT study sheds light on the underlying neural mechanism. "This study shows us one way that the brain changes when its inputs change. Neurons seem to 'want' to receive input: when their usual input disappears, they start responding to the next best thing," said Nancy K...

Arana updates inflammatory pipeline milestones

October 19, 2019

ART123 was produced using Arana's proprietary antibody engineering technologies. Patents have been filed around the novel mechanism of action of ART123, which has demonstrated efficacy in a pre-clinical psoriasis model. Preclinical safety studies are expected to commence in 2010. Arana has developed and tested several new formulations of PMX53 in animal models of AMD, psoriasis and osteoarthritis. The AMD clinical trial is expected to start in the first half of 2009, subject to the successful ...

Zinc and macular degeneration link

October 18, 2019

In studying eye tissue samples, the researches found that deposits, that are hallmarks of age-related macular degeneration (AMD), contain large amounts of zinc. This finding, published in the journal Experimental Eye Research, might be particularly important because zinc supplements are widely given to patients to help boost weak immune systems. In addition, a 2001 study from the National Eye Institute found that high doses of zinc supplements, combined with antioxidants, may postpone the prog...

Bionic eye offers light at the end of the tunnel for the blind

October 17, 2019

If all goes well the bionic eye implant could be available to patients within two years and could help restore the sight of millions of blind people. The prototype device, the Argus II system, will be tested in 50 to 75 patients at five centres across the U.S. and uses a spectacle-mounted camera to feed visual information to electrodes in the eye. Early tests with less-advanced versions of the retinal implant enabled patients to see light, shapes and movement. Professor Mark Humayun, from th...

Blindness added to the risk list of obesity

October 16, 2019

Britain, along with many other developed countries, has an increasing number of obese people and one in five adults and children in the UK is now considered to be obese. The situation is such that the Department of Health recently warned that as many as a third of men in England would be obese by 2010 if no measures were taken to tackle the problem. The RNIB report says obesity is already recognized as one of the leading preventable causes of death from heart disease and diabetes but it is als...
