Gene Therapy Proves Effective In Treating Blindness
Researchers from the Perelman School of Medicine at the University of Pennsylvania and The Children's Hospital of Philadelphia have conducted a recent study, published in Science Translational Medicine which focuses on gene therapy for congenital blindness. The scientists were able to improve sight in 3 adult patients who had previously been treated in one eye. The researchers used the same treatment on the second eye of the patients, and they were able to see in low-light situations and also find their way around. There were no conflicting effects reported... (Source: Health News from Medical News Today)

Abstract
Determining the fate of emerging organic contaminants in an aquatic ecosystem is important for developing constructed wetlands (CWs) treatment technology. Experiments were carried out in subsurface flow CWs in Singapore to evaluate the fate and transport of eight pharmaceutical compounds. The CW system included three parallel horizontal subsurface flow CWs and three parallel unplanted beds fed continuously with synthetic wastewater at different hydraulic retention times (HRTs). The findings of the tests at 2-6d HRTs showed that the pharmaceuticals could be categorized as (i) efficiently removed compounds with removal higher than 85% (ketoprofen and salicylic acid); (ii) moderately removed compounds with removal ...
