Freiburger Neurowissenschaftler erschließen neue Diagnose- und Therapiewege bei Schläfenlappenepilepsie

Heute vom Fahrrad gestürzt und in zehn Jahren an Epilepsie erkrankt? Solche Zusammenhänge wirken weit hergeholt, sind aber durchaus möglich, sagen Freiburger Forscherinnen und Forscher. Mithilfe neuester Verfahren der Magnetresonanztomografie haben Prof. Dr. Carola Haas, Klinik für Neurochirurgie, Prof. Dr. Jürgen Hennig, Klinik für Radiologie, und Prof. Dr. Ulrich Egert, Institut für Mikrosystemtechnik der Universität Freiburg, in Zusammenarbeit mit Prof. Dr. Jan Korvink vom Karlsruher Institut für Technologie gezeigt, wie bestimmte Störungen des Hippocampus eine medikamentenresistente Epilepsie in Gang setzen.

Im Laufe des Alterns und durch verschiedene Krankheiten wie Diabetes oder Krebs verändern sich Proteine im Körper – zumeist durch ungewünschte Reaktionen mit verschiedenen Stoffwechselprodukten wie z.B. Methylglyoxal. Ein Team um Maria Matveenko und Christian F. W. Becker vom Institut für Biologische Chemie der Universität Wien hat nun zum ersten Mal auf molekularer Ebene die biochemischen Konsequenzen einer solchen Modifikation untersucht – ein Durchbruch in der Analyse von Proteinen. Die Ergebnisse der Studie erscheinen aktuell im renommierten Fachmagazin “Angewandte Chemie”. (more…)

Neue Methode der Proteinmodifizierung verbessert Behandlung und Diagnostik von Krebs.

Viele moderne Diagnostika und Therapeutika basieren auf Proteinen, die nur auf Grund bestimmter Modifikationen ihre komplexen Funktionen in unseren Zellen übernehmen können. Ein Team um Christian F. W. Becker vom Institut für Biologische Chemie der Universität Wien hat nun eine neue Methode entwickelt, die den schnellen Zugang zu modifizierten Peptiden und Proteinen ermöglicht, die für die Behandlung und Diagnostik von Krebs eingesetzt werden können. Die Ergebnisse der Studie erscheinen aktuell im renommierten Fachmagazin “Angewandte Chemie”. (more…)

Advance in tuberous sclerosis brain science

By manipulating the timing of disease-causing mutations in the brains of developing mice, Brown University researchers have found that early genetic deletions in the thalamus may play an important role in course and severity of the developmental disease tuberous sclerosis complex. Findings appear in the journal Neuron.

PROVIDENCE, R.I. [Brown University] — Doctors often diagnose tuberous sclerosis complex (TSC) based on the abnormal growths the genetic disease causes in organs around the body. Those overt anatomical structures, however, belie the microscopic and mysterious neurological differences behind the disease’s troublesome behavioral symptoms: autism, intellectual disabilities, and seizures. In a new study in mice, Brown University researchers highlight a role for a brain region called the thalamus and show that the timing of gene mutation during thalamus development makes a huge difference in the severity of the disease.

Effort to Enforce HIV ‘Health Threat’ Law Raises Questions

ANN ARBOR — Michigan health officials are using HIV surveillance technologies to assist in enforcing a “health threat” law that makes it illegal for HIV-positive people to have sex without disclosing their status.

A new University of Michigan study reveals that health officials employ the state’s names reporting database, alongside partner services referrals, for law enforcement purposes. However, this is bad social policy for a variety of reasons, says Trevor Hoppe, the study’s author and a doctoral candidate in sociology and women’s studies. (more…)

Researchers seek better ways to diagnose, treat disorder

Tania Roth studies what happens to the brain when stress occurs early in life, seeking to pinpoint how those kinds of bad experiences can cause molecular changes to DNA.

Now, by participating in a national consortium of researchers, the assistant professor of psychology at the University of Delaware is hoping to use her expertise to contribute to a better understanding of posttraumatic stress disorder (PTSD). (more…)

Gaming system a new step for telepathology and other telemedicine fields

Online crowd-sourcing — in which a task is presented to the public, who respond, for free, with various solutions and suggestions — has been used to evaluate potential consumer products, develop software algorithms and solve vexing research-and-development challenges. But diagnosing infectious diseases?

Working on the assumption that large groups of public non-experts can be trained to recognize infectious diseases with the accuracy of trained pathologists, researchers from the UCLA Henry Samueli School of Engineering and Applied Science and the David Geffen School of Medicine at UCLA have created a crowd-sourced online gaming system in which players distinguish malaria-infected red blood cells from healthy ones by viewing digital images obtained from microscopes.
