Using Phosphorus Recovery from Wastewater as a Context for Teaching Sustainable Development with USEPA P3 Support

Phosphorus is an essential element required for agriculture. Current practices include one-way use of phosphorus: that is mining; production of fertilizer; land application; and ultimately loss to aquatic sediments. Once in the aquatic environment, phosphorus stimulates eutrophication resulting in the death of water bodies. With financial support from a People, Prosperity, and Planet program grant of the U.S. Environmental Protection Agency, an interdisciplinary team of faculty at the University of Cincinnati used phosphorus recovery from sewage and re-utilization as a struvite fertilizer as the context for a year-long course of study integrating graduate and undergraduate students in Environmental Engineering and Science as well as Environmental Studies. This presentation will highlight the original course format, results of student assessment from the 2004-2005 academic year, modifications incorporated for the 2005-2006 academic year, and the subsequent findings of student perceptions and learning. The challenge of integrating across two colleges within a comprehensive university system will be discussed, and our approaches for meeting the learning needs and course expectations of a diverse student population will be included

A Response to the IPCC Fifth Assessment

The Intergovernmental Panel on Climate Change\u27s (IPCC) Fifth Assessment Report presented significant data and findings about climate change. But the IPCC\u27s working groups\u27 summaries for policymakers avoid making normative statements about the IPCC\u27s findings. The authors, members of the Environmental Law Collaborative, bridge this gap by identifying the normative claims that stem from the working groups\u27 summaries to spark deeper discussion and help shape the IPCC\u27s sixth assessment

A Response to the IPCC Fifth Assessment

This collection of essays is the initial product of the second meeting of the Environmental Law Collaborative, a group of environmental law scholars that meet to discuss important and timely environmental issues. Here, the group provides an array of perspectives arising from the Fifth Assessment of the Intergovernmental Panel on Climate Change. Each scholar chose one passage from one of the IPCC’s three Summaries for Policymakers as a jumping-off point for exploring climate change issues and responding directly to the reports. The result is a variety of viewpoints on the future of how law relates to climate change, a result that is the product not only of each scholar’s individual knowledge but also of the group’s robust discussion

CD4⁺CD25⁻ T Cells Transduced to Express MHC Class I-Restricted Epitope-Specific TCR Synthesize Th1 Cytokines and Exhibit MHC Class I-Restricted Cytolytic Effector Function in a Human Melanoma Model

Cytolytic T cell-centric active specific and adoptive immunotherapeutic approaches might benefit from the simultaneous engagement of CD4⁺ T cells. Considering the difficulties in simultaneously engagingCD4⁺ and CD8⁺ T cells in tumor immunotherapy, especially in an Ag-specific manner, redirecting CD4⁺ T cells to MHC class I-restricted epitopes through engineered expression of MHC class I-restricted epitope-specific TCRs in CD4⁺ T cells has emerged as a strategic consideration. Such TCR-engineered CD4⁺ T cells have been shown to be capable of synthesizing cytokines as well as lysing target cells. We have conducted a critical examination of functional characteristics of CD4⁺ T cells engineered to express the α- and β-chains of a high functional avidity TCR specific for the melanoma epitope, MART-1, as a prototypic human tumor Ag system. We found that unpolarized CD4⁺CD25⁻ T cells engineered to express the MART-1 TCR selectively synthesize Th1 cytokines and exhibit a potent Ag-specific lytic granule exocytosis-mediated cytolytic effector function of comparable efficacy to that of CD8⁺ CTL. Such TCR engineered CD4⁺ T cells, therefore, might be useful in clinical immunotherapy

Genome-Wide Association of Bipolar Disorder Suggests an Enrichment of Replicable Associations in Regions near Genes

Although a highly heritable and disabling disease, bipolar disorder's (BD) genetic variants have been challenging to identify. We present new genotype data for 1,190 cases and 401 controls and perform a genome-wide association study including additional samples for a total of 2,191 cases and 1,434 controls. We do not detect genome-wide significant associations for individual loci; however, across all SNPs, we show an association between the power to detect effects calculated from a previous genome-wide association study and evidence for replication (P = 1.5×10−7). To demonstrate that this result is not likely to be a false positive, we analyze replication rates in a large meta-analysis of height and show that, in a large enough study, associations replicate as a function of power, approaching a linear relationship. Within BD, SNPs near exons exhibit a greater probability of replication, supporting an enrichment of reproducible associations near functional regions of genes. These results indicate that there is likely common genetic variation associated with BD near exons (±10 kb) that could be identified in larger studies and, further, provide a framework for assessing the potential for replication when combining results from multiple studies

Long-term influence of normal variation in neonatal characteristics on human brain development

It is now recognized that a number of cognitive, behavioral, and mental health outcomes across the lifespan can be traced to fetal development. Although the direct mediation is unknown, the substantial variance in fetal growth, most commonly indexed by birth weight, may affect lifespan brain development. We investigated effects of normal variance in birth weight on MRI-derived measures of brain development in 628 healthy children, adolescents, and young adults in the large-scale multicenter Pediatric Imaging, Neurocognition, and Genetics study. This heterogeneous sample was recruited through geographically dispersed sites in the United States. The influence of birth weight on cortical thickness, surface area, and striatal and total brain volumes was investigated, controlling for variance in age, sex, household income, and genetic ancestry factors. Birth weight was found to exert robust positive effects on regional cortical surface area in multiple regions as well as total brain and caudate volumes. These effects were continuous across birth weight ranges and ages and were not confined to subsets of the sample. The findings show that (i) aspects of later child and adolescent brain development are influenced at birth and (ii) relatively small differences in birth weight across groups and conditions typically compared in neuropsychiatric research (e.g., Attention Deficit Hyperactivity Disorder, schizophrenia, and personality disorders) may influence group differences observed in brain parameters of interest at a later stage in life. These findings should serve to increase our attention to early influences
