PROBLEM: Paragraph: It is not clear whether turning on the gaspers in the cabins of commercial airliners actually improves the air quality. To answer this question, this study first developed a hybrid turbulence model which was suitable for predicting the air distribution in an aircraft cabin with gaspers turned on. Next, the investigation validated the model using two sets of experimental data from a cabin mockup and an actual airplane. This study then used the validated model to systematically investigate the impact of gaspers on cabin air quality in a seven-row section of the fully-occupied, economy-class cabin of Boeing 767 and 737 airplanes. The CFD calculations formed a database consisting of 9660 data points that provide information about SARS infection risk. It was found that the distribution of opened gaspers can influence the infection risk for passengers. Even though the gasper supplies clean air, it is possible for it to have a negative impact on the passengers' health. Statistically speaking, the overall effect of turning on the gaspers on the mean infection risk for the general population was neutral.

PROBLEM: Paragraph: Multiple sclerosis (MS) is a debilitating disease of the central nervous system (CNS) that has been extensively studied using the animal model experimental autoimmune encephalomyelitis (EAE). It is believed that CD4 + T lymphocytes play an important role in the pathogenesis of this disease by mediating the demyelination of neuronal axons via secretion of proinflammatory cytokines resulting in the clinical manifestations. Although a great deal of information has been gained in the last several decades about the cells involved in the inflammatory and disease mediating process, important questions have remained unanswered. It has long been held that initial neuroantigen presentation and T cell activation events occur in the immune periphery and then translocate to the CNS. However, an increasing body of evidence suggests that antigen (Ag) presentation might initiate within the CNS itself. Importantly, it has remained unresolved which antigen presenting cells (APCs) in the CNS are the first to acquire and present neuroantigens during EAE/MS to T cells, and what the conditions are under which this takes place, ie, whether this occurs in the healthy CNS or only during inflammatory conditions and what the related cytokine microenvironment is comprised of. In particular, the central role of interferon-g as a primary mediator of CNS pathology during EAE has been challenged by the emergence of Th17 cells producing interleukin-17. This review describes our current understanding of potential APCs in the CNS and the contribution of these and other CNS-resident cells to disease pathology. Additionally, we discuss the question of where Ag presentation is initiated and under what conditions neuroantigens are made available to APCs with special emphasis on which cytokines may be important in this process.

SOLUTION: True

PROBLEM: Paragraph: The pathogenesis of SARS-CoV remains largely unknown. To study the function of the SARS-CoV nucleocapsid protein, we have conducted a yeast twohybrid screening experiment to identify cellular proteins that may interact with the SARS-CoV nucleocapsid protein. Pyruvate kinase (liver) was found to interact with SARS-CoV nucleocapsid protein in this experiment. The binding domains of these two proteins were also determined using the yeast two-hybrid system. The physical interaction between the SARS-CoV nucleocapsid and cellular pyruvate kinase (liver) proteins was further confirmed by GST pull-down assay, co-immunoprecipitation assay and confocal microscopy. Cellular pyruvate kinase activity in hepatoma cells was repressed by SARS-CoV nucleocapsid protein in either transiently transfected or stably transfected cells. PK deficiency in red blood cells is known to result in human hereditary non-spherocytic hemolytic anemia. It is reasonable to assume that an inhibition of PKL activity due to interaction with SARS-CoV N protein is likely to cause the death of the hepatocytes, which results in the elevation of serum alanine aminotransferase and liver dysfunction noted in most SARS patients. Thus, our results suggest that SARS-CoV could reduce pyruvate kinase activity via its nucleocapsid protein, and this may in turn cause disease.
