The challenge of epilepsy research is to develop novel treatments for patients where classical therapy is inadequate. Using a new protocol—with the help of an implantable drug delivery system—we are able to control seizures in anesthetized mice by the electrophoretic delivery of GABA into the epileptic focus.

¹Faculty of Sports Science, Ningbo University, ²School of Health and Life Sciences, University of the West of Scotland, ³Faculty of Engineering, University of Szeged

This study compared the biomechanical characteristics of the lower extremity during unplanned gait termination under different walking speeds. The lower-limb kinematic and kinetic data from fifteen subjects with normal and fast walking speeds were collected using a motion analysis system and plantar pressure platform.

Visualizing and Quantifying Endonuclease-Based Site-Specific DNA Damage

Vasiliki Pantazi^*1, Ivett Berzsenyi^*1, Barbara N. Borsos¹, Tibor Pankotai¹

¹Institute of Pathology, Faculty of Medicine, University of Szeged

This article introduces essential steps of immunostaining and chromatin immunoprecipitation. These protocols are commonly used to study DNA damage-related cellular processes and to visualize and quantify the recruitment of proteins implicated in DNA repair.
