Senckenberg-Wissenschaftler haben erstmalig Borrelien in deutschen Stechmücken nachgewiesen. Die drei identifizierten Arten der Bakterien können beim Menschen die Multisystemerkrankung Lyme-Borreliose auslösen. In ihrer kürzlich im Fachjournal „Ticks and Tick-borne Diseases“ veröffentlichten Studie zeigen die Forschenden außerdem, dass die Krankheitserreger die Umwandlung der Mückenlarve zur Puppe und schließlich zum erwachsenen Tier überleben. Auch wenn die Mücken potentielle Borreliose-Vektoren sein können, spielen sie nach derzeitigem Erkenntnisstand höchstens eine untergeordnete Rolle bei der Übertragung der Krankheitserreger. (more…)

University of Chicago researchers have developed a method to diagnose pancreatic cancer earlier in patients. By collecting samples from the portal vein—which carries blood from the gastrointestinal tract, including from the pancreas, to the liver—physicians can learn far more about a patient’s pancreatic cancer than by relying on peripheral blood from a more easily accessed vein in the arm.

UCLA study finds most patients who choose “active surveillance” don’t follow up with tests and office visits

An increasing number of men diagnosed with low-risk prostate cancer are opting for active surveillance – closely monitoring their cancer – rather than aggressive treatment to avoid the debilitating potential side effects of surgery and radiation, such as erectile and urinary dysfunction. (more…)

Freiburger Wissenschaftler entschlüsselt Gehirnprozesse bei der unbewussten Bewertung sozialer Gruppen

Innerhalb von wenigen Millisekunden bewerten Menschen ihr Gegenüber und entscheiden, ob die Person ihnen sympathisch ist oder nicht. Der Freiburger Psychologe und Neurowissenschaftler Dr. Bastian Schiller hat mit einem Team an der Universität Basel/Schweiz sowie an der Universität Bern/Schweiz erstmals herausgefunden, welche unbewusst ablaufenden Hirnprozesse in welcher zeitlichen Abfolge dafür verantwortlich sind, dass Menschen soziale Informationen wie zum Beispiel Sympathie oder Antipathie verarbeiten. Die Ergebnisse sind in der aktuellen Ausgabe des US-amerikanischen Fachjournals „Proceedings of the National Academy of Sciences“ (PNAS) erschienen. (more…)
