Traumatic brain injury (TBI) is a disruption in the brain functions following a head trauma. Cell therapy may provide a promising treatment for TBI. Human neural stem cells cultured in self-assembling peptide scaffolds have been proposed as a potential novel method for cell replacement treatment after TBI. In the present study, we accessed the effects of human neural stem/progenitor cells (hNS/...

In this paper we present the construction of a highly-interactive computer-supported film set (CSFS) by using elements of contextual design and UML models. Specific aspects of usability, domain functionality, cost, realtime and robustness requirements for systems which are used on the set for supporting the production of feature films and commercials are discussed. Contextual design can lead to...

Various organizations increasingly adopt open source software, both on desktop PCs and servers. Since the first movements in open source in the 1960’s its growth has lead to new approaches in software development, licensing, and distribution, as well as in software vendors’ business models. The literature includes very interesting studies regarding prospective benefits, business models and case...

Astrocytes regulate synaptic transmission through controlling neurotransmitter concentrations around synapses. Little is known, however, about their roles in neural circuit development. Here we report that Bergmann glia (BG), specialized cerebellar astrocytes that thoroughly enwrap Purkinje cells (PCs), are essential for synaptic organization in PCs through the action of the l-glutamate/l-aspar...

The impact of the 1994 North American Free Trade Agreement (NAFTA) on relatively disadvantaged groups, including Mexican women, has provoked heated debate for over a decade and continues to divide opinions on NAFTA’s merits. This study uses a differences-in-differences approach to examine how NAFTA affected the female labor participation rate (FLP) in different Mexican regions. NAFTA increased ...
