Iowa 2088 Summer Storms After-Action Report Final, April 27, 2009

In the summer of 2008, the state of Iowa suffered from a series of severe storms that produced tornadoes and heavy rainfall, which resulted in widespread flooding. The Summer Storms1 lasted from late May through mid-August, with the most intense storms occurring over a month-long period from May 25 to June 25. The Summer Storms exacted a major human and economic toll on Iowa, resulting in 18 fatalities and 106 injuries, forcing the evacuation of approximately 38,000 Iowans, and impacting 21,000 housing units. Iowa’s public and private sectors suffered significant monetary damages. Eighty-six of the ninety-nine counties in the state were included in the Governor’s disaster declarations. Presidential disaster declarations made residents in 84 counties eligible for Public Assistance and 78 counties for Individual Assistance. The Rebuild Iowa Advisory Commission estimated $798.3 million in damages to publicly owned buildings and infrastructure, including damages of $53 million to public transportation and $342 million to public utilities. The 2008 Summer Storms presented unique coordination challenges for the Iowa Homeland Security and Emergency Management Division (HSEMD) and the State Emergency Operations Center (SEOC). These challenges arose from three interrelated factors: the large number of local jurisdictions and areas impacted, the prolonged period of time that response operations were conducted, and the increasing complexity of overall response operations. These events caused the SEOC to coordinate response, mitigation, recovery, and preparedness operations simultaneously. HSEMD and the SEOC implemented a variety of measures to enhance their ability to coordinate operations and assistance to localities. The SEOC expanded its organizational structure, implemented innovative techniques, and incorporated new partners into its activities. These steps enabled HSEMD and SEOC to coordinate operations more effectively, which undoubtedly helped save lives and property, while mitigating the effects of the 2008 Summer Storms.

Derivation of the gauge-invariant action for open and closed free bosonic string field theories

The gauge-invariant actions for open and closed free bosonic string field theories are obtained from the string field equations in the conformal gauge using the cohomology operations of Banks and Peskin. For the closed-string theory no restrictions are imposed on the gauge parameters.

Das Auerhuhn im Jura: Qualität des Lebensraum, Demographie, Habitatwahl und nicht-invasive genetische Untersuchungen

Most Central European Capercaillie populations have been declining during the last century. In the Jura Mountains, at the border between Switzerland and France, remaining Capercaillie populations are now isolated and endangered. In this study, land-use and Capercaillie presence data were used to identify key landscape parameters by logistic regression modelling. We found that Capercaillie prefers areas at the highest altitude in the Jura Mountains that are characterised by continous forests and stands with intermediate canopy cover. At the local scale, winter habitat selection revealed a preference for open forests with a sparse canopy cover dominated by spruce and fir. Capercaillie avoided dense undercanopy and understorey, especially when dominated by beech. Population viability and sensitivity analyses underlined the crucial importance of adult female survival, chick survival and breeding success for populations maintenance. Legal bases, scientific knowledge and technical measures are now available to conserve the flagship species Capercaillie within Jura Mountains. Capercaillie-adapted forestry requires a mosaic distribtution of habitat types, with a matrix of open forests where fir is favoured, and understorey kept sparse. Preliminary essays indicate that grouse-adapted forestry costs are similar or even lower than present costs. To increase survival and breeding sucess, one option is to diminish human distrubance by limiting access to Capercailllie breeding and wintering areas. An action plan for the species should avoid more costly and intensive approaches such as the reintroduction of birds from other populations. Capercaillie conservaiton represents a major challenge rising from various and contradictory leisure, tourist and rural development activities. Collaborations with different stakeholders and state agencies for forestry with an effective protection from human distrubance.

Place des antiarthrosiques symptomatiques d'action lente dans l'arthrose (sulfate de chondroïtine, glucosamine, acide hyaluronique) [Role of slow-acting anti-arthritic agents in osteoarthritis (chondroitin sulfate, glucosamine, hyaluronic acid)].

Osteoarthritis (OA) is one of the major causes of pain and of outpatient's clinics. 15 years ago, physiopathology of OA and its potential therapeutic targets were announced to be better understood, but the results of therapeutic trials were finally not as convincing as expected. Slow Acting Drugs (SADs) are part of the treatments evaluated in OA. Even if evidence based medicine is low, positive effects of SADs have been observed. We can reasonably propose these treatments for a short test period. It can sometimes enable us to decrease the dosage of others treatment such as NSAIDs. In any case, the physician must properly inform the patient about products available in Switzerland and must be aware of degrees of purity and costs of the products available on the intemet.

Molecular genetics of ocular diseases

The eye is a complex organ, which provides one of our most important senses, sight. The retina is the neuronal component of the eye and represents the connection with the central nervous system for the transmission of the information that leads to image processing. Retinitis pigmentosa (RP) is one of the most common forms of inherited retinal degeneration, in which the primary death of rods, resulting in night blindness, is always followed by the loss of cones, which leads to legal blindness. Clinical and genetic heterogeneity in retinitis pigmentosa is not only due to different mutations in different genes, but also to different effects of the same mutation in different individuals, sometimes even within the same family. My thesis work has been mainly focused on an autosomal dominant form of RP linked to mutations in the PRPF31 gene, which often shows reduced penetrance. Our study has led to the identification of the major regulator of the penetrance of PRPF31 mutations, the CNOT3 protein, and to the characterization of its mechanism of action. Following the same rationale of investigating molecular mechanisms that are responsible for clinical and genetic heterogeneity of retinitis pigmentosa, we studied a recessive form of the disease associated with mutations in the recently-identified gene FAMI61 A, where mutations in the same gene give rise to variable clinical manifestations. Our data have increased the knowledge of the relationship between genotype and phenotype in this form of the disease. Whole genome sequencing technique was also tested as a strategy for disease gene identification in unrelated patients with recessive retinitis pigmentosa and proved to be effective in identifying disease-causing variants that might have otherwise failed to be detected with other screening methods. Finally, for the first time we reported a choroidal tumor among the clinical manifestations of PTEN hamartoma tumor syndrome, a genetic disorder caused by germline mutations of the tumor suppressor gene PTEN. Our study has highlighted the heterogeneity of this choroidal tumor, showing that genetic and/or epigenetic alterations in different genes may contribute to the tumor development and growth. - L'oeil est un organe complexe, à l'origine d'un de nos sens les plus importants, la vue. La rétine est la composante neuronale de l'oeil qui constitue la connexion avec le système nerveux central pour la transmission de l'information et qui conduit à la formation des images. La rétinite pigmentaire (RP) est une des formes les plus courantes de dégénérescence rétinienne héréditaire, dans laquelle la mort primaire de bâtonnets, entraînant la cécité nocturne, est toujours suivie par la perte de cônes qui conduit à la cécité complète. L'hétérogénéité clinique et génétique dans la rétinite pigmentaire n'est pas seulement due aux différentes mutations dans des gènes différents, mais aussi à des effets différents de la même mutation chez des individus différents, parfois même dans la même famille. Mon travail de thèse s'est principalement axé sur une forme autosomique dominante de RP liée à des mutations dans le gène PRPF31, associées souvent à une pénétrance réduite, me conduisant à l'identification et à la caractérisation du mécanisme d'action du régulateur principal de la pénétrance des mutations: la protéine CNOT3. Dans la même logique d'étude des mécanismes moléculaires responsables de l'hétérogénéité clinique et génétique de la RP, nous avons étudié une forme récessive de la maladie associée à des mutations dans le gène récemment identifié FAMI61 A, dont les mutations dans le même gène donnent lieu à des manifestations cliniques différentes. Nos données ont ainsi accru la connaissance de la relation entre le génotype et le phénotype dans cette forme de maladie. La technique de séquençage du génome entier a été ensuite testée en tant que stratégie pour l'identification du gène de la maladie chez les patients atteints de RP récessive. Cette approche a montré son efficacité dans l'identification de variantes pathologiques qui n'auraient pu être détectées avec d'autres méthodes de dépistage. Enfin, pour la première fois, nous avons identifié une tumeur choroïdienne parmi les manifestations cliniques du PTEN hamartoma tumor syndrome, une maladie génétique causée par des mutations germinales du gène suppresseur de tumeur PTEN. Notre étude a mis en évidence l'hétérogénéité de cette tumeur choroïdienne, montrant que les altérations génétiques et/ou épigénétiques dans les différents gènes peuvent contribuer au développement et à la croissance tumorale.

Role of the GNOM gene in Arabidopsis apical-basal patterning--From mutant phenotype to cellular mechanism of protein action.

How the apical-basal axis of polarity is established in embryogenesis is still a mystery in plant development. This axis appeared specifically compromised by mutations in the Arabidopsis GNOM gene. Surprisingly, GNOM encodes an ARF guanine-nucleotide exchange factor (ARF-GEF) that regulates the formation of vesicles in membrane trafficking. In-depth functional analysis of GNOM and its closest relative, GNOM-LIKE 1 (GNL1), has provided a mechanistic explanation for the development-specific role of a seemingly mundane trafficking regulator. The current model proposes that GNOM is specifically involved in the endosomal recycling of the auxin-efflux carrier PIN1 to the basal plasma membrane in provascular cells, which in turn is required for the accumulation of the plant hormone auxin at the future root pole through polar auxin transport. Thus, the analysis of GNOM highlights the importance of cell-biological processes for a mechanistic understanding of development.

Molecular mechanisms of action of herbal antifungal alkaloid berberine, in Candida albicans.

Candida albicans causes superficial to systemic infections in immuno-compromised individuals. The concomitant use of fungistatic drugs and the lack of cidal drugs frequently result in strains that could withstand commonly used antifungals, and display multidrug resistance (MDR). In search of novel fungicidals, in this study, we have explored a plant alkaloid berberine (BER) for its antifungal potential. For this, we screened an in-house transcription factor (TF) mutant library of C. albicans strains towards their susceptibility to BER. Our screen of TF mutant strains identified a heat shock factor (HSF1), which has a central role in thermal adaptation, to be most responsive to BER treatment. Interestingly, HSF1 mutant was not only highly susceptible to BER but also displayed collateral susceptibility towards drugs targeting cell wall (CW) and ergosterol biosynthesis. Notably, BER treatment alone could affect the CW integrity as was evident from the growth retardation of MAP kinase and calcineurin pathway null mutant strains and transmission electron microscopy. However, unlike BER, HSF1 effect on CW appeared to be independent of MAP kinase and Calcineurin pathway genes. Additionally, unlike hsf1 null strain, BER treatment of Candida cells resulted in dysfunctional mitochondria, which was evident from its slow growth in non-fermentative carbon source and poor labeling with mitochondrial membrane potential sensitive probe. This phenotype was reinforced with an enhanced ROS levels coinciding with the up-regulated oxidative stress genes in BER-treated cells. Together, our study not only describes the molecular mechanism of BER fungicidal activity but also unravels a new role of evolutionary conserved HSF1, in MDR of Candida.
