Gene therapy reverses genetic mutation responsible for heart failure in muscular dystrophy

...normal hearts, when examined at eight and one-half months after gene therapy. The adult hamsters also showed significant improvements in heart muscle structure. In contrast, untreated hamsters had severe structural and tissue abnormalities of the heart in addition to secondary symptoms of heart failure such...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

...s. This benign therapy could potentially eliminate months of debilitating chemotherapy and radiation treatment, he adds. "The laser we used is a 3-centimeter beam that's held like a flashlight," he notes. "We can take the beam and put anywhere we want. We can shine it on a local area of the skin or inside ...

Gene therapy works in mice to prevent blindness that strikes boys

...valent to retinoschisis in a 10-year-old boy. Six months later, researchers looked at the interior of the eyes with a laser ophthalmoscope and found cyst formation was clearly evident in the untreated eyes, but the treated eyes appeared healthy. The eye's photoreceptor cells - the rods and cones that help ...

Plant genes identified that can form basis for crops better adapted to environmental conditions

...arly as 1937, scientists knew that it takes only 4 months for a single rye plant to produce some 13 million individual roots! But up to now, the genetic basis of this complex process has remained unexplained. The production of new roots is a complex combination of cell division, growth and differentiation....

PLoS Medicine publishes first trial of effect of male circumcision on HIV infection

...umcised until after the completion of the trial 21 months later. The circumcised men were instructed to abst...rticipants over 21 months, testing them for HIV at months 3, 12 and 21, to see whether there was a difference in the rate of new infections between the two gr...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...ethane, for example, are five months, 52 hours, 13 months and 72 years, respectively." In contrast, the half-life of the potato pesticide residue chloroacrylate -- 10,000 years -- matches the half-life of plutonium-239, the hazardous isotope produced in nuclear power plants, he said. The bacteria Pseudomo...

Chernobyl: The true scale of the accident

...ighly exposed rescue workers, many who died within months of the accident but others who died as late as 2004. The new numbers are presented in a landmark digest report, "Chernobyl's Legacy: Health, Environmental and Socio-Economic Impacts," just released by the Chernobyl Forum. The digest, based on a thre...

Zinc supplements safe for HIV-infected children

Zebrafish may hold key to improved cancer research

...ssible drug therapies, and might tell you in three months what it would take two years to find out with other animal models." "This low cost, efficient research should speed up drug development, save many millions of dollars and help lead to new cancer therapies." Using zebrafish, OSU has extensively studi...

Swimming with dolphins can alleviate depression

... mammals' healing properties, they suggest. Three months after the study, participants in both groups also reported lasting improvement and did not require treatment. This suggests that in patients with mild or moderate depression, using drugs or conventional psychotherapy may not be necessary when biophil...

Fresh water affected by salt from deicing roads

Dr. Kaushal of the University of Maryland Center for Environmental Science Appalachian Laboratory said, "There i...

NIAID researchers show how promising TB drug works

...a complete genome comparison might have taken many months of work; this new technology enables scientists to zero in on the specific genetic difference between mutant and normal bacterial strains in just days, says Dr. Barry. The scientists found a total of four PA-824-resistant mutant strains: two lacked ...

Clinical trial to test stem cell approach for children with brain injury

Safety trials involve too few patients to draw broad conclusions about the effectiveness of tr...

Cells from amniotic fluid used to tissue-engineer a new trachea

...CDH; the amniotic fluid would be collected several months before birth and a tissue-engineered patch made ready for use soon after delivery. His team is also working on stem-cell-based, tissue-engineered grafts to fix spina bifida (in which the spinal column doesn't close fully during fetal development) and...

Sangamo BioSciences demonstrates its ZFP treatment protects cells from HIV infection

... drugs to block HIV binding to CCR5, but in recent months two trials have been halted, one due to reports of liver toxicity of the candidate drug. We believe that using ZFNs to permanently modify the CCR5 gene specifically in T-cells and thus directly block the expression of the protein on the surface of t...

Implantable pumps extend lives of patients too sick for transplant

"When researchers discover an important trait - for example, that a certain species is resistant to disease - then everyt...

Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects

...e could improve Stat1 efficiency during the winter months in patients at risk of developing serious viral infections, including children with asthma, heart disease or compromised immune systems." It may be possible, as well, to screen patients for levels of Stat1 responsiveness and use the same treatment ...

Effective, safe anthrax vaccine can be grown in tobacco plants
