The Soil and Water Assessment Tool:Historical Development, Applications, and Future Research Directions, 2007

The Soil and Water Assessment Tool (SWAT) model is a continuation of nearly 30 years of modeling efforts conducted by the U.S. Department of Agriculture (USDA), Agricultural Research Service. SWAT has gained international acceptance as a robust interdisciplinary watershed modeling tool, as evidenced by international SWAT conferences, hundreds of SWAT-related papers presented at numerous scientific meetings, and dozens of articles published in peer-reviewed journals. The model has also been adopted as part of the U.S. Environmental Protection Agency’s BASINS (Better Assessment Science Integrating Point & Nonpoint Sources) software package and is being used by many U.S. federal and state agencies, including the USDA within the Conservation Effects Assessment Project. At present, over 250 peer-reviewed, published articles have been identified that report SWAT applications, reviews of SWAT components, or other research that includes SWAT. Many of these peer-reviewed articles are summarized here according to relevant application categories such as streamflow calibration and related hydrologic analyses, climate change impacts on hydrology, pollutant load assessments, comparisons with other models, and sensitivity analyses and calibration techniques. Strengths and weaknesses of the model are presented, and recommended research needs for SWAT are provided.

Iowa's Rural Alzheimer's Demonstration Project, July 1, 2004 - June 31, 2007

The Iowa Department of Elder Affairs, in collaboration with the Iowa Department of Elder Affairs (IDEA) and the University of Iowa College of Nursing (UI CON), has been engaged in developing and evaluating community based services for persons with dementia in the state of Iowa over the past 7 years under two grants form the Administration on Aging. In the current grant period, the involved agencies have completed a collaborative effort aimed to increase the capacity of Adult Day Health and Respite (ADR) providers in serving persons with dementia. Adult day services and respite care were identified by participants in the initial grant through various processes and service providers as important components of caring for persons with dementia and that there was a gap of these services in the state. Therefore, adult day and respite services were chosen as a target for the second AoA grant. The focus, in particular, was to enhance capacity to care for persons with later stages of the disease and those in rural settings as well as to begin to develop services that are more responsive to emerging minority populations. The process of the grant provided the state with a rich amount of information about the status of Iowa’s Adult Day Service providers in general and in regard to provision of dementia specific services, as well as valuable insights into the capability of rural communities to serve persons with dementia and their caregivers at home.

Inflammasome activation by adenylate cyclase toxin directs Th17 responses and protection against Bordetella pertussis.

Inflammasome-mediated IL-1beta production is central to the innate immune defects that give rise to certain autoinflammatory diseases and may also be associated with the generation of IL-17-producing CD4(+) T (Th17) cells that mediate autoimmunity. However, the role of the inflammasome in driving adaptive immunity to infection has not been addressed. In this article, we demonstrate that inflammasome-mediated IL-1beta plays a critical role in promoting Ag-specific Th17 cells and in generating protective immunity against Bordetella pertussis infection. Using a murine respiratory challenge model, we demonstrated that the course of B. pertussis infection was significantly exacerbated in IL-1R type I-defective (IL-1RI(-/-)) mice. We found that adenylate cyclase toxin (CyaA), a key virulence factor secreted by B. pertussis, induced robust IL-1beta production by dendritic cells through activation of caspase-1 and the NALP3-containing inflammasome complex. Using mutant toxins, we demonstrate that CyaA-mediated activation of caspase-1 was not dependent on adenylate cyclase enzyme activity but was dependent on the pore-forming capacity of CyaA. In addition, CyaA promoted the induction of Ag-specific Th17 cells in wild-type but not IL-1RI(-/-) mice. Furthermore, the bacterial load was enhanced in IL-17-defective mice. Our findings demonstrate that CyaA, a virulence factor from B. pertussis, promotes innate IL-1beta production via activation of the NALP3 inflammasome and, thereby, polarizes T cell responses toward the Th17 subtype. In addition to its known role in subverting host immunity, our findings suggest that CyaA can promote IL-1beta-mediated Th17 cells, which promote clearance of the bacteria from the respiratory tract.
