1004-002 Rathbun Lake Watershed Final Report

The Rathbun Land and Water Alliance and partners have undertaken a highly effective approach to water quality protection through the Rathbun Lake Special Project. This approach is achieving a significant reduction in the sediment and phosphorus that impair water quality in Rathbun Lake and its tributaries as a result of the targeted application of best management practices (BMPs) for priority land in the watershed. This application proposes to assist landowners to construct five large sediment retention basins that will reduce sediment and phosphorus delivery from priority land in targeted sub-watersheds. The Alliance, with previous WIRB support, demonstrated that construction of these basins at strategically selected sites is one of the most cost effective measures to reduce sediment and phosphorus delivery to Rathbun Lake. Features of this project are: (1) use of geographic information system (GIS) analysis to identify potential basin sites; (2) assistance for landowners to construct 5 basins that will reduce the annual delivery of sediment by 1,500 tons and phosphorus by 5,000 pounds; (3) evaluation of the benefits from basin construction using GIS analysis and water quality monitoring; and (4) watershed outreach activities that encourage landowners to apply BMPs including sediment retention basins to protect water quality.

Features of this project are: (1) use of geographic information system (GIS) analysis to identify priority land that requires BMPs; (2) assistance for landowners to apply BMPs for 4,000 acres that will reduce the annual delivery of sediment by 6,000 tons and phosphorus by 20,000 pounds; (3) evaluation of the benefits from BMP application using GIS analysis and water quality monitoring; and (4) watershed outreach activities that encourage landowners to apply BMPs for priority land to protect water quality.

08027-016 Competine Creek Watershed Final Report

Competine Creek is an 8,653 acre subwatershed of Whitebreast Creek which drains directly to Lake Red Rock. The Marion Soil and Water Conservation District has prioritized water quality protection efforts within Competine Creek subwatershed because 1) this watershed has been identified as a significant contributor of sediment, nutrients, and bacteria to Competine Creek and Lake Red Rock, 2) the watershed provides unique outreach opportunities due to its unique rural and urban interface, and 3) by using a targeted approach to address water quality, the likelihood of successfully demonstrating water quality improvements is high due to its manageable size. The specific goals of this proposal to WIRB (Phase I) are to: 1) reduce sediment and nutrient delivery by 1787 tons and 2144 lbs by installing conservation practices on high priority agricultural land; and 2) install urban conservation practices that reduce the volume of peak flow, improve streambank stability, and promote infiltration of stormwater runoff before it enters Competine Creek. The Marion SWCD has assembled a unique group of partners and secured funding from multiple sources to implement this project.

07013-004 Rathbun Lake Watershed Final Report

The Rathbun Land and Water Alliance and partners have implemented a uniquely effective approach to water quality protection through the Rathbun Lake Special Project. This approach is achieving a significant reduction in the sediment and phosphorus that impair water quality in Rathbun Lake and its tributaries as a result of the targeted application of best management practices (BMPs) for priority land in the watershed. This project application proposes to assist landowners to apply BMPs that will reduce sediment and phosphorus delivery from priority land in four targeted sub-watersheds as part of the Rathbun Lake Special Project. Features of this project are: (1) use of geographic information system (GIS) analysis to identify priority land that requires BMPs; (2) assistance for landowners to apply BMPs on 5,100 acres that will reduce the annual delivery of sediment by 8,130 tons and phosphorus by 35,980 pounds; (3) evaluation of the benefits from BMP application using GIS analysis and water quality monitoring; and (4) watershed outreach activities that encourage landowners to apply BMPs for priority land to protect water quality.

06014-007 Lower Coldwater-Palmer Creek Watershed Final Report

Lower Coldwater and Palmer Creeks in Butler and Floyd counties are subwatersheds of the Cedar River, which provides drinking water to Cedar Rapids, IA. The increasing concentration of nitrate+nitrate in the river is of concern to the Cedar Rapids water utility, and IDNR snapshot monitoring shows Coldwater and Palmer to be significant potential sources (above the 90th percentile for subwatersheds monitored). Both creeks are also on the Iowa Section 303(d) list of impaired waters (aquatic life). Citizens of these predominantly agricultural watersheds organized the Coldwater-Palmer Watershed Improvement Association to deal proactively with nonpoint source pollutants from crop and livestock operations through a performance-based environmental management program. The locally-adapted program implemented by the Coldwater-Palmer watershed council rewards participants for environmental accomplishments - soil quality improvement and nutrient source reduction as measured by accepted, scientifically-based tests and models. Most of the locally­appropriate BMPs used to improve performance are undertaken voluntarily at participants' initiative. WIRB funds will be combined with funding from the Iowa Com Growers Association and significant in-kind support from the Cedar River Watershed Monitoring Coalition, Iowa State University Extension and other partners. The project will result in sustainable reduction in nutrient loading achieved with voluntary participation of a majority of watershed farm operators.

06025-012 Rathbun Lake Watershed Final Report

The Rathbun Land and Water Alliance and partners have implemented a unique approach to water quality protection through the Rathbun Lake Special Project. This approach is achieving a significant reduction in the sediment and phosphorus that impair water quality in Rathbun Lake and its tributaries as a result of the targeted application of best management practices (BMPs) for priority land in the watershed. This project application proposes to assist landowners to apply BMPs that will reduce sediment and phosphorus delivery from priority land in two targeted sub-watersheds as part of the Rathbun Lake Special Project Features of this project are: (1) use of geographic information system (GIS) analysis to identify priority land that requires BMPs; (2) assistance for landowners to apply BMPs on more than 2,200 acres that will reduce sediment and phosphorus delivery by 3,300 tons and 13,300 pounds per year respectively; (3) evaluation of the benefits from BMP application using GIS analysis and water quality monitoring; and (4) watershed outreach activities that encourage landowners to apply BMPs for priority land to protect water quality.

05028-010 Urban Watershed of Dickinson Cty Lakes Final Report

The Dickinson SWCD is applying for $486,800 over three years from the Watershed Improvement Fund to enhance water quality in Dickinson County through an impairment-based, locally directed watershed improvement project dealing specifically with storm water runoff. The LID Project will provide a cost share incentive and technical expertise to individual and business owners in specially targeted districts who are willing to implement low impact development techniques such as rain gardens, bioswales, pervious paving to reduce storm water runoff from their properties. Goals for the project include: 1) Defining and prioritizing urban watersheds in the Iowa Great Lakes region for implementation of Low Impact Development Practices; 2) Providing technical expertise in the form of a graduate assistant/project manager to design and oversee construction; 3) Continuing public education of such practices and their local existence through project kiosk, brochures, County Naturalist programs, local cable television shows, tours and other interactions of the Clean Water Alliance with its 50 partners in the area concerned about water quality; and 4) Completing 125 separate projects over a three year period.

07032-012 Lake MacBride Watershed Final Report

Lake Macbride is considered to be one of the top four lakes for fishing in the state of Iowa. It is widely used by the public and contributes significant economic benefits to the county. Lake Macbride is situated in the North Corridor which is one of the fastest growing areas in the state. The lake has a surface area of 940 acres and drains 16,205 acres. Lake Macbride is on the Iowa 303(d) list for excessive sediments and nutrients. In 2001, Lake Macbride State Park received over 2.5 million dollars from the Marine Fuel Tax and Fish and Wildlife Trust to install 2 silt basins and stabilize over 12 miles of shoreline in the lake. Also in 2001, the Johnson County SWCD received a WSPF allocation from DSC to address agriculture and urban runoff issues in the watershed. Section 319 funding was received in 2002 to continue watershed efforts to the present. A watershed assessment was completed in 2003 to guide watershed activities. In 2005, a TMDL was completed for the lake. Since 2001, over $645,000 dollars has been spent by landowners and funding partners to install conservation practices in the watershed. Watershed efforts have resulted in the reduction of over 4200 tons of soils from being delivered into Lake Macbride. Nutrient reductions have also occurred from the development of nutrient management plans on 2000 acres. The District is in the process of wrapping up watershed efforts on private land. A series of 13 structures is planned to be installed in the State Park over the next several years. One of the last remaining items that still needs addressed is 1,400 feet of eroding shoreline adjacent to Lake Macbride along Cottage Reserve Road. The road is under the jurisdiction of the Johnson County Board of Supervisors. Both the Board of Supervisors and the IDNR are willing to contribute substantial dollars to address the 250 tons of soil that are being directly delivered to Lake Macbride each year.

1204-003 North Fork Maquoketa Watershed Final Report

The Headwaters North Fork Maquoketa River Project encompasses the Hewitt Creek, Bear Creek, and the Coffee Creek-North Fork Maquoketa subwatersheds. These three.sub-watersheds have intensive livestock agriculture production with manures applied generously on the landscape. Approximately 85% of the watershed area is cropland. Although livestock operations are not permitted to discharge waste directly into surface waters, the mishandling and over-application of animal waste and fertilizer have impacted water quality. Each of the subwatersheds has a strong locally led effort, concentrating significant efforts on monitoring, education, and conservation practice adoption. The original MRBI application was accepted by USDA with funding being extended to producers through FY14. A large component of this effort was the IJOBS funds awarded by IDALS to support the Project Coordinator for the first two years of this project. As previous funding for the support of the Project Coordinator has been exhausted, the local partners identified WIRB as a potential replacement funding source. The goal of the existing MRBI effort, in being consistent with this WIRB application, will help landowners and operators in the three selected watersheds voluntarily implement conservation systems that reduce nutrient loss; protect, restore, and enhance wetlands; maintain agricultural productivity; improve wildlife habitat; and achieve other objectives, such as flood reduction.

1214-008 Clear Lake Watershed Final Report

Clear Lake, Iowa's third largest natural lake, is a premier natural resource and popular recreational destination in north central Iowa. Despite the lake's already strong recreational use, water quality concerns have not allowed the lake to reach its full potential. Clear Lake is listed on Iowa's Draft 2010 303(d) Impaired Waters List for algae, bacteria, and turbidity. Many restoration practices have been implemented to treat the algae and turbidity impairment, but few practices have been installed to treat bacteria. Reducing beach bacteria levels is a priority of the lake restoration partners. Federal, State, and local partners have invested more than $20 million in lake and watershed restoration efforts to improve water clarity and quality. These partners have a strong desire to ensure high bacteria levels at public swim beaches do not undermine the other water quality improvements. Recent bacteria source tracking completed by the State Hygienic Laboratory indicates that Canada Geese are a major contributor of bacteria loading to the Clear Lake swim beaches. Other potential sources include unpermitted septic systems in the watershed. The grant request proposes to reduce bacteria levels at Clear Lake's three public swim beaches by utilizing beach cleaner machines to remove goose waste, installing goose deterrents at the swim beaches, and continuing a septic system update grant program. These practices began to be implemented in 2011 and recent bacteria samples in 2012 are showing they can be effective if the effort is continued.

1231-014 Twelve Mile Lake Watershed Final Report

Twelve Mile Creek Lake is a 660 acre, Significant Publicly Owned Lake with a watershed of 14,820 acres for a ratio of 21:3. The watershed is predominately privately owned agricultural land that originates in Adair County and drains into the lake which serves as the primary source water for the City of Creston, Union County and the seven counties served by the Southern Iowa Rural Water Association. In recent years, frequent algae blooms and recurrent spikes in suspended solid concentrations have been inflating water treatment expenses for the Creston Municipal Utilities (CMU). Declining trends in water quality spurred CMU to enlist the Union Soil and Water Conservation District (SWCD) to assist in evaluating watershed conditions for potential upland improvements. Significant gully erosion issues that had been previously underestimated were discovered during this watershed assessment process. Newly acquired LiDAR elevation data readily revealed this concern which was previously obscured from view by the dense tree canopy. A Watershed Development and Planning Assistance Grant Application was approved and funded by the Iowa Department of Ag and Land Stewardship- Division of Soil Conservation. Throughout the planning process, project partners innovatively evaluated and prioritized a number of resource concerns throughout the watershed. The implementation plan presented will thwart these threats which left unaided will continue to diminish the overall health of the system, reduce the appeal of the lake to recreational users, and contribute to higher water treatment costs.

Please refer to previous reports for this information. The annual report serves as an informational resource for stakeholders, local partners, policy makers and others interested in Iowa’s TB Control efforts.

Mechanistic insights into cytosolic molecular chaperones in protein unfolding and disaggregation

Under optimal non-physiological conditions of low concentrations and low temperatures, proteins may spontaneously fold to the native state, as all the information for folding lies in the amino acid sequence of the polypeptide. However, under conditions of stress or high protein crowding as inside cells, a polypeptide may misfold and enter an aggregation pathway resulting in the formation of misfolded conformers and fibrils, which can be toxic and lead to neurodegenerative illnesses, such as Alzheimer's, Parkinson's or Huntington's diseases and aging in general. To avert and revert protein misfolding and aggregation, cells have evolved a set of proteins called molecular chaperones. Here, I focussed on the human cytosolic chaperones Hsp70 (DnaK) and HspllO, and co-chaperone Hsp40 (DnaJ), and the chaperonin CCT (GroEL). The cytosolic molecular chaperones Hsp70s/Hspll0s and the chaperonins are highly upregulated in bacterial and human cells under different stresses and are involved both in the prevention and the reversion of protein misfolding and aggregation. Hsp70 works in collaboration with Hsp40 to reactivate misfolded or aggregated proteins in a strict ATP dependent manner. Chaperonins (CCT and GroEL) also unfold and reactivate stably misfolded proteins but we found that it needed to use the energy of ATP hydrolysis in order to evict over- sticky misfolded intermediates that inhibited the unfoldase catalytic sites. Ill In this study, we initially characterized a particular type of inactive misfolded monomeric luciferase and rhodanese species that were obtained by repeated cycles of freeze-thawing (FT). These stable misfolded monomeric conformers (FT-luciferase and FT-rhodanese) had exposed hydrophobic residues and were enriched with wrong ß-sheet structures (Chapter 2). Using FT-luciferase as substrate, we found that the Hsp70 orthologs, called HspllO (Sse in yeast), acted similarly to Hsp70 as were bona fide ATP- fuelled polypeptide unfoldases and was much more than a mere nucleotide exchange factor, as generally thought. Moreover, we found that HspllO collaborated with Hsp70 in the disaggregation of stable protein aggregates in which Hsp70 and HspllO acted as equal partners that synergistically combined their individual ATP-consuming polypeptide unfoldase activities to reactivate the misfolded/aggregated proteins (Chapter 3). Using FT-rhodanese as substrate, we found that chaperonins (GroEL and CCT) could catalytically reactivate misfolded rhodanese monomers in the absence of ATP. Also, our results suggested that encaging of an unfolding polypeptide inside the GroEL cavity under a GroES cap was not an obligatory step as generally thought (Chapter 4). Further, we investigated the role of Hsp40, a J-protein co-chaperone of Hsp70, in targeting misfolded polypeptides substrates onto Hsp70 for unfolding. We found that even a large excess of monomeric unfolded a-synuclein did not inhibit DnaJ, whereas, in contrast, stable misfolded a-synuclein oligomers strongly inhibited the DnaK-mediated chaperone reaction by way of sequestering the DnaJ co-chaperone. This work revealed that DnaJ could specifically distinguish, and bind potentially toxic stably aggregated species, such as soluble a-synuclein oligomers involved in Parkinson's disease, and with the help of DnaK and ATP convert them into from harmless natively unfolded a-synuclein monomers (chapter 5). Finally, our meta-analysis of microarray data of plant and animal tissues treated with various chemicals and abiotic stresses, revealed possible co-expressions between core chaperone machineries and their co-chaperone regulators. It clearly showed that protein misfolding in the cytosol elicits a different response, consisting of upregulating the synthesis mainly of cytosolic chaperones, from protein misfolding in the endoplasmic reticulum (ER) that elicited a typical unfolded protein response (UPR), consisting of upregulating the synthesis mainly of ER chaperones. We proposed that drugs that best mimicked heat or UPR stress at increasing the chaperone load in the cytoplasm or ER respectively, may prove effective at combating protein misfolding diseases and aging (Chapter 6).  - Dans les conditions optimales de basse concentration et de basse température, les protéines vont spontanément adopter un repliement natif car toutes les informations nécessaires se trouvent dans la séquence des acides aminés du polypeptide. En revanche, dans des conditions de stress ou de forte concentration des protéines comme à l'intérieur d'une cellule, un polypeptide peu mal se replier et entrer dans un processus d'agrégation conduisant à la formation de conformères et de fibrilles qui peuvent être toxiques et causer des maladies neurodégénératives comme la maladie d'Alzheimer, la maladie de Parkinson ou la chorée de Huntington. Afin d'empêcher ou de rectifier le mauvais repliement des protéines, les cellules ont développé des protéines appelées chaperonnes. Dans ce travail, je me suis intéressé aux chaperonnes cytosoliques Hsp70 (DnaK) et HspllO, la co-chaperones Hsp40 (DnaJ), le complexe CCT/TRiC et GroEL. Chez les bactéries et les humains, les chaperonnes cytosoliques Hsp70s/Hspl 10s et les « chaperonines» sont fortement activées par différentes conditions de stress et sont toutes impliquées dans la prévention et la correction du mauvais repliement des protéines et de leur agrégation. Hsp70 collabore avec Hsp40 pour réactiver les protéines agrégées ou mal repliées et leur action nécessite de 1ATP. Les chaperonines (GroEL) déplient et réactivent aussi les protéines mal repliées de façon stable mais nous avons trouvé qu'elles utilisent l'ATP pour libérer les intermédiaires collant et mal repliés du site catalytique de dépliage. Nous avons initialement caractérisé un type particulier de formes stables de luciférase et de rhodanese monomériques mal repliées obtenues après plusieurs cycles de congélation / décongélation répétés (FT). Ces monomères exposaient des résidus hydrophobiques et étaient plus riches en feuillets ß anormaux. Ils pouvaient cependant être réactivés par les chaperonnes Hsp70+Hsp40 (DnaK+DnaJ) et de l'ATP, ou par Hsp60 (GroEL) sans ATP (Chapitre 2). En utilisant la FT-Luciferase comme substrat nous avons trouvé que HspllO (un orthologue de Hsp70) était une authentique dépliase, dépendante strictement de l'ATP. De plus, nous avons trouvé que HspllO collaborait avec Hsp70 dans la désagrégation d'agrégats stables de protéines en combinant leurs activités dépliase consommatrice d'ATP (Chapitre 3). En utilisant la FT-rhodanese, nous avons trouvé que les chaperonines (GroEL et CCT) pouvaient réactiver catalytiquement des monomères mal repliés en absence d'ATP. Nos résultats suggérèrent également que la capture d'un polypeptide en cours de dépliement dans la cavité de GroEL et sous un couvercle du complexe GroES ne serait pas une étape obligatoire du mécanisme, comme il est communément accepté dans la littérature (Chapitre 4). De plus, nous avons étudié le rôle de Hsp40, une co-chaperones de Hsp70, dans l'adressage de substrats polypeptidiques mal repliés vers Hsp70. Ce travail a révélé que DnaJ pouvait différencier et lier des polypeptide mal repliés (toxiques), comme des oligomères d'a-synucléine dans la maladie de Parkinson, et clairement les différencier des monomères inoffensifs d'a-synucléine (Chapitre 5). Finalement une méta-analyse de données de microarrays de tissus végétaux et animaux traités avec différents stress chimiques et abiotiques a révélé une possible co-expression de la machinerie des chaperonnes et des régulateurs de co- chaperonne. Cette meta-analyse montre aussi clairement que le mauvais repliement des protéines dans le cytosol entraîne la synthèse de chaperonnes principalement cytosoliques alors que le mauvais repliement de protéines dans le réticulum endoplasmique (ER) entraine une réponse typique de dépliement (UPR) qui consiste principalement en la synthèse de chaperonnes localisées dans l'ER. Nous émettons l'hypothèse que les drogues qui reproduisent le mieux les stress de chaleur ou les stress UPR pourraient se montrer efficaces dans la lutte contre le mauvais repliement des protéines et le vieillissement (Chapitre 6).

The Evolution of Sexual Dysfunction in Young Men Aged 18-25 Years

PURPOSE: To assess the evolution of sexual dysfunctions among young males after an average of 15 months follow-up to determine the predictive factors for this evolution and the characteristics differentiating young males who continue reporting a sexual dysfunction from those who do not. METHODS: We conducted a prospective cohort study in two Swiss military recruitment centers mandatory for all Swiss national males aged 18-25 years. A total of 3,700 sexually active young males filled out a questionnaire at baseline (T0) and follow-up (T1: 15.5 months later). Main outcome measures were self-reported premature ejaculation (PE) and erectile dysfunction (ED). RESULTS: Overall, 43.9% of young males who reported (PE) and 51% of those reporting (ED) at T0 still reported it at T1. Moreover, 9.7% developed a PE problem and 14.4% developed an ED problem between T0 and T1. Poor mental health, depression, and consumption of medication without prescription were predictive factors for PE and ED. Poor physical health, alcohol consumption, and less sexual experience were predictive factors for PE. ED persistence was associated with having multiple sexual partners. CONCLUSIONS: This is the first longitudinal study to examine sexual dysfunctions among young males. Our results show high prevalence rates among young males for maintaining or developing a sexual dysfunction over time. Consequently, when consulting with young males, health professionals should inquire about sexual dysfunctions as part of their routine psychosocial assessment and leave the subject open for discussion. Future research should examine in more detail the relationship between sexual dysfunctions and poor mental health.

La Campanya gastronòmica del Peix Blau Ganxó: dels seus orígens a l'actualitat

La realització d’aquest estudi té per objectiu principal analitzar l’activitat promocional de la Costa Brava, com ho és la campanya gastronòmica del Peix Blau Ganxó. Es tracta d’analitzar quina ha estat la seva evolució des de què va néixer la campanya fins a l’actualitat. S’estudien diferents aspectes com, per exemple, l’èxit que ha anat obtenint, les maneres de promoció que s’han anat utilitzant per difondre la campanya, les empreses col•laboradores, a quins diaris s’hi han publicat notes de premsa i alguns aspectes d’imatge gràfica. Un segon objectiu és realitzar un treball de recerca basat en l’organització de la campanya gastronòmica en la seva setzena edició. Això permet desenvolupar un projecte ben documentat i en el qual s’ha pogut extreure la informació necessària de primera mà. Un tercer objectiu és donar a conèixer una de les activitats gastronòmiques amb més ressò del Baix Empordà. Són moltes campanyes de gastronomia que es celebren als diferents municipis de la comarca. Algunes d’elles tenen una trajectòria exitosa de més de 15 anys. La idea és estudiar-ne una en concret per a valorar com es desenvolupa una activitat d’aquesta mena que no té altre objectiu primordial que el d’atraure el turisme i desestacionalitzar la temporada de la Costa Brava
