Are mosaic embryos the ‘dark horse’ of IVF? Study in nonhuman primates gives new hope to people seeking infertility treatment; abnormal embryos can result in successful in vitro fertilization

Not every embryo contains 46 perfect chromosomes. Some have more, others have fewer. The result is a common abnormality known as aneuploidy, which occurs in as many as 80 percent of human embryos. Because aneuploidy has been linked to a risk of in vitro fertilization failure, miscarriage and certain genetic…

Long-lived parents produce better quality offspring

Genetic manipulation that more than doubles lifespan also leads to better offspring — according to new collaborative research from the University of East Anglia and Uppsala University. Researchers studied a gene, known as DAF-2, which is associated with ageing in roundworms (Caenorhabditis elegans). They found that by reducing this gene’s…

Drug interactions in ER’s common but preventable

In a recent Rutgers study, 38 percent of patients discharged from the emergency department had at least one drug interaction resulting from a newly prescribed medicine. The study, which was published in the American Journal of Emergency Medicine, identified the most common prescription drug combinations that may result in a…

Genetic clues to high rates of asthma in those of African ancestry: Scientists discover areas of chromosomes associated with asthma, a complex disease with striking disparities across racial/ethnic groups

In the largest study of its kind, researchers at the University of Colorado Anschutz Medical Campus have found new clues into the parts of the human genome associated with the higher rates of asthma in those of African ancestry. The study was published today in the journal Nature Communications. Using…

New genes associated with the leading cause of blindness

A new study, published in Clinical Epigenetics, identifies genes associated with Age-related Macular Degeneration (AMD) that could represent new targets for future drug development. AMD is the leading cause of blindness in the UK and affects more than 200 million of people worldwide. The condition results in a gradual loss…
