Sammanfattning : In a time when the very last Holocaust witnesses will soon be gone, a possible route for commemoration is to ask what testimony images can give. This book seeks to answer the question of how images can bear witness by examining them as multifaceted entities produced, reproduced, and resituated in conflicting political and historical situations.

2. Genetic mechanisms regulating proliferation and cell specification in the Drosophila embryonic CNS
Sammanfattning : The central nervous system (CNS) consists of an enormous number of cells, and large cellular variance, integrated into an elaborate network. The CNS is the most complex animal organ, and therefore its establishment must be controlled by many different genetic programs. LÄS MER
Sammanfattning : The human central nervous system (CNS) contains a daunting number of cells and tremendous cellular diversity. A fundamental challenge of developmental neurobiology is to address the questions of how so many different types of neurons and glia can be generated at the precise time and place, making precisely the right connections.

Sammanfattning : Amyloid diseases are caused by protein misfolding and aggregation. To date there are 27 known proteins causing amyloid disorders involving brain and peripheral protein deposition. The proteins involved in this mechanism do not share sequence homology, but the amyloid fibrils share biophysical properties and possibly a common pathogenic mechanism. LÄS MER
5. Genetic pathways controlling CNS development : The role of Notch signaling in regulating daughter cell proliferation in Drosophila
Sammanfattning : The human central nervous system (CNS) displays the greatest cellular diversity of any organ system, consisting of billions of neurons, of numerous cell sub-types, interconnected in a vast network. Given this enormous complexity, decoding the genetic programs controlling the multistep process of CNS development remains a major challenge. LÄS MER
