AUSTIN, Texas — Scientists at The University of Texas at Austin have discovered a mechanism that may explain how the brain can recall nearly all of what happened on a recent afternoon — or make a thorough plan for how to spend an upcoming afternoon — in a fraction of the time it takes to live out the experience. The breakthrough in understanding a previously unknown function in the brain has implications for research into schizophrenia, autism spectrum disorders, Alzheimer’s disease and other disorders where real experiences and ones that exist only in the mind can become distorted.

A review of more than 30 studies seeking answers about silicone gel breast implant safety finds that the studies don’t provide definitive evidence. The new paper may help inspire improved analyses of existing data as well as a new registry to provide better data.

PROVIDENCE, R.I. [Brown University] — Uncertainty about safety has swirled around silicone gel breast implants for years. They were suspended from the market in 1992 and then allowed again in 2006. Throughout, despite many studies, definitive evidence about whether they are linked to health problems ranging from cancer to connective tissue disorders to depression has remained elusive. (more…)

Anpassungsfähige Stimulation könnte Patienten mit neurologischen Erkrankungen wie Parkinson deutlich entlasten

Könnten beim Einsatz tiefer Hirnstimulation zur Behandlung von Parkinson potenzielle Nebenwirkungen mithilfe eines so genannten geschlossenen Regelkreises vermieden werden, der sich individuell an die Symptome der Patientin oder des Patienten anpasst? Mit dieser Frage beschäftigen sich der Neurowissenschaftler Dr. Ioannis Vlachos und seine Kollegen Taskin Deniz, Prof. Dr. Arvind Kumar und Prof. Dr. Ad Aertsen in einer aktuellen Studie, die in der Fachzeitschrift „PLoS Computational Biology“ erschienen ist.

Schimmelpilzinfektion in der Lunge frühzeitig entdecken

Wissenschaftler finden bildgebende Methode, um Befall im Körper sichtbar zu machen

Sie sind winzig klein, überall in der Luft und jeder von uns atmet sie täglich ein: Sporen des Schimmelpilzes Aspergillus fumigatus. Gesunden Menschen bereitet das in der Regel keine Probleme, die körpereigene Immunabwehr tötet die Eindringlinge, bevor sie sich im Körper festsetzen können. Bei Menschen, deren Immunsystem jedoch stark geschwächt ist – etwa Leukämie- oder AIDS-Patienten sowie Knochenmarkempfängern – nistet sich der Pilz ohne große Gegenwehr in der Lunge ein und verursacht dort die sogenannte invasive Aspergillose. Diese gefährliche Infektionskrankheit ist eine der häufigsten Todesursachen bei immungeschwächten Patienten. Eine frühzeitige und auf die Patienten abgestimmte Therapie ist für den Krankheitsverlauf entscheidend, wurde aber bisher durch den Mangel an schnellen und gleichzeitig zuverlässigen Diagnosemöglichkeiten erschwert.
