Controversy is the main instrument by which Judaism develops and shapes its philosophy, theology and law. The rabbinical literature speaks with many voices, debating virtually every subject, and failing to reach a consensus on many. However, this willingness to condone controversy is accompanied by much deliberation. Controversy, and its legal, philosophical and social ramifications, was and remains of unparalleled concern to the rabbis. Today, we are also witness to a burgeoning academic interest in controversy and pluralism in Jewish law.

This book is an anthology of passages from the rabbinical literature that address the phenomenon of controversy in Jewish law, affording the English-speaking reader the opportunity for a first-hand encounter with this fascinating material. An extensive analytical introduction contextualizes the material from a philosophical perspective.

Hamodynamische Perfusionseinschrankungen des Gehirns tragen in bis zu 10% der Falle zur Entstehung eines ischamischen Schlaganfalls bei. Eine konservative, kausale Therapie ist gegenwartig nicht verfugbar. Die derzeitige Therapie der Wahl zur Senkung des Schlaganfallrisikos besteht aus einer Verbesserung des zerebralen Kollateralblutflusses mittels operativer Revaskularisierung, beispielsweise durch Anlage eines extra- intrakraniellen Bypasses. Zwecks Erforschung von neuen, therapeutischen Strategien zur kunstlichen Stimulation des zerebralen Kollateralgefasswachstums (Arteriogenese) beschreibt die vorliegende Arbeit die tierexperimentelle Modellentwicklung einer chronisch zerebralen Ischamie bei der C57/BL6 Maus, dem am weitesten verbreiteten Hintergrundstamm zur Zuchtung von transgenen Mauslinien
