(Press-News.org) Orlando, Fla. — Scientists have developed the first reversible glue that could be used on the battlefield to treat eye injuries, potentially saving soldiers' vision. The research is being presented at the 2014 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Orlando, Fla.
When applied to a wounded eye, the adhesive warms up and becomes sticky, sealing the wound and minimizing further damage while the soldier is transported for treatment. Upon arriving at a hospital, doctors can simply apply cool saline solution to the glue, causing it to revert to its non-adhesive form and be removed with minimal discomfort.
Improvised explosive devices (IEDs) have increased the frequency of military-related eye injuries to 16% of all injuries reported. Once the eye is punctured, loss of internal fluids can lead to retinal detachment and vision loss if not prevented.
Abstract Title: Thermoresponsive Reversible Adhesive for Temporary Intervention in Ocular Trauma

WHI reports $37.1B economic return on combined hormone therapy clinical trial
2014-05-06
SEATTLE – Economic findings were released today on the Women's Health Initiative (WHI), estrogen plus progestin (E+P) trial. The WHI is one of the largest National Institutes of Health-funded studies ever conducted on women. Housed at the Fred Hutchinson Cancer Research Center in Seattle, it is a 15-year, multimillion-dollar study established in 1991, involving more than 160,000 women nationwide, including some 3,500 in Washington.
The overall economic return from the WHI E+P trial indicates that changes in practice stemming from the trial provided a net economic return ...
Novel antioxidant makes old arteries seem young again, CU-Boulder study finds
2014-05-06
An antioxidant that targets specific cell structures—mitochondria—may be able to reverse some of the negative effects of aging on arteries, reducing the risk of heart disease, according to a new study by the University of Colorado Boulder.
When the research team gave old mice—the equivalent of 70- to 80-year-old humans—water containing an antioxidant known as MitoQ for four weeks, their arteries functioned as well as the arteries of mice with an equivalent human age of just 25 to 35 years.
The researchers believe that MitoQ affects the endothelium, a thin layer of cells ...
Cataract surgery decreases risk of falls in older patients
2014-05-06
Orlando, Fla. — New research finds that cataract surgery dramatically decreases the number of falls individuals suffer due to poor vision. The research is being presented at the 2014 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Orlando, Fla.
In a study of more than 400 Vietnamese patients who were 50-plus years old with cataracts in both eyes, the number of falls patients suffered before and after cataract surgery was monitored. Researchers found a 78% decrease in the risk of falls the year after patients had cataract ...
Simulated model of eye's 3D structure facilitates stem cells transplant
2014-05-06
Orlando, Fla. — Scientists have developed a model that mimics the complex structure of the cornea to enable the transplant of healthy corneal stem cells. The research is being presented at the 2014 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Orlando Fla.
Used to restore sight, corneal stem cells live in a specific physical environment. Transplanting these stem cells requires accurate mimicry of their natural surroundings during transport. In this work, vision scientists have recreated the 3D architecture where corneal ...
Astronomers harness the galaxy's biggest telescope
2014-05-06
An international team of astronomers has made a measurement of a distant neutron star that is one million times more precise than the previous world's best.
The researchers were able to use the interstellar medium, the 'empty' space between stars and galaxies that is made up of sparsely spread charged particles, as a giant lens to magnify and look closely at the radio wave emission from a small rotating neutron star.
This technique yielded the highest resolution measurement ever achieved, equivalent to being able to see the double-helix structure of our genes from the ...
A novel transgenic mouse model of Chinese Charcot-Marie-Tooth disease type 2L
2014-05-06
Dr. Ruxu Zhang and colleagues from Third Xiangya Hospital, Central South University in China previously found that the K141N mutation in heat shock protein B8 (HSPB8) was responsible for Charcot-Marie-Tooth disease type 2L in a large Chinese family. Therefore, they generated a transgenic mouse model bearing the K141N mutation in the human HSPB8 gene, and to determine whether this K141NHSPB8 transgenic mouse model would manifest the clinical phenotype of Charcot-Marie-Tooth disease type 2L, and consequently be suitable for use in studies of disease pathogenesis. The K141NHSPB8 ...
Regulatory effects of glial cells on retinal synaptic plasticity
2014-05-06
Different types of retinal damage could induce plastic changes of retinal synapses, which might precede the serious damage of neuron soma. These morphological and functional changes to synapses after retinal injury could explain why many intervention measures protected neurons from death but failed to fully recover the damaged visual function. Therefore, it is necessary to investigate both the protection of synapses as well as protecting neurons from death. Dr. Lihong Zhou and co-workers from Central South University in China suggested that retinal glial cell activation ...
The Pael-R gene does not mediate the changes in rotenone-induced PD model cells
2014-05-06
Currently, the pathogenesis of Parkinson's disease is not entirely clear, but it has been generally considered to be the result of interactions among various genetic and environmental factors. Ting Zou and coworkers from Second Xiangya Hospital, Central South University in China previously found that Parkin mutation causes Parkin-associated endothelin receptor-like receptor (Pael-R) protein deposition, and the associated cytotoxicity leads to dopaminergic neuronal apoptosis. These researchers speculated that the Pael-R gene is possibly involved in the action of rotenone ...
AMPK and inflammatory mediators are involved in postoperative cognitive dysfunction
2014-05-06
Postoperative cognitive dysfunction is associated with neuronal apoptosis, which may result from post-surgery inflammation, the phosphorylation of tau protein and the accumulation of amyloid in aged people. 5′adenosine monophosphate-activated protein kinase (AMPK) can be involved in anti-inflammation, neuronal repair and anti-inflammation of the body through different downstream proteins and pathways. In addition, the activation of AMPK regulates tau protein phosphorylation and reduces amyloidogenesis in neurons. Yanlin Bi and co-workers from the Affiliated Qianfoshan ...
Danish social workers have become the moral agents of the state
2014-05-06
"We are turning the professional social workers into moral agents. This development recalls a time before the welfare state, when we had poor relief and when the extent to which the state could help you depended on your own dignity."
This is the assertion by Marie Østergaard Møller, who is associate professor at the Department of Political Science and Government, Aarhus University regarding the labour market policy that has been carried out in Denmark since the 1990s. More specifically, since 1994 the opportunities for citizens to get relief from the state have been reduced. ...
