1. Nasal polyps. A clinical study of endoscopic score systems and epidemiology
Abstract : Introduction: Nasal polyps are a common disease, the etiology and pathogenesis of which are still unclear. For diagnosis, a nasal endoscope is essential, while for follow-up treatment, a reliable score system is necessary. The existing score systems consist of few score steps and measure only large changes in polyp size. READ MORE

3. Adult human neural stem cells : properties in vitro and as xenografts in the spinal cord
Abstract : Though the presence of stem cells in the adult human brain has been presented earlier, much has yet to be discovered about these cells. However, the mere potential of these cells has had a significant impact of how we today evaluate the regenerative capacity of the central nervous system and, importantly, on the possible means for science to provide insights in neural repair.

5. Particulate Formation in GDI Engines
Abstract : The need to comply with stringent emission regulations while improving fuel economy and reducing criteria pollutant emissions from transportation presents a major challenge in the design of gasoline Direct Injection (DI) engines because of the adverse effects of ultrafine Particulate Number (PN) emissions on human health and other environmental concerns. With upcoming advances in vehicle electrification, it may be the case that electric vehicles completely replace all current vehicles powered by internal combustion engines ensuring zero emissions.
