Antisense Therapy Shows Promise Against Parkinson's

Parkinson's disease (PD), as well as many other neurodegenerative disorders, has shown a link between the abnormal aggregation of a protein called α-synuclein (aSyn) and neuronal death. These aggregates, known as Lewy bodies and Lewy neurites depending on their subcellular localization, can spread by continuously causing normal endogenous aSyn to misfold.

Researchers Discover How Common Bacteria can Accelerate Wound Closure in Diabetics

There are many important reasons for keeping cuts and sores clean, but new research from the Perelman School of Medicine at the University of Pennsylvania shows that a certain bug, Alcaligenes faecalis (A. faecalis), can facilitate healing of hard-to-treat wounds among people with diabetes.

New Insights into the Neural Mechanisms Underlying Infant Attachment

Specific neurons in the brain's zona incerta (ZI) play a crucial role in the early social interactions of an infant and its mother, building their bond and reducing stress, according to a new study in mice. Activation of the same neurons in adult mice increased anxiety- and fear-like responses, the study showed.

Cost-Effective Array Sheds Light on Imprinted Gene Regulation

Researchers from North Carolina State University have developed an array that assesses methylation levels of genes located in imprint control regions (ICRs) within the human genome. The array represents a cost-effective, efficient method for exploring potential links between environmental exposures and epigenetic dysregulation during the early developmental origins of diseases and behavioral disorders.
