Mechanisms of symptomatic spinal cord ischemia after TEVAR: insights from the European Registry of Endovascular Aortic Repair Complications (EuREC)

To test the hypothesis that simultaneous closure of at least 2 independent vascular territories supplying the spinal cord and/or prolonged hypotension may be associated with symptomatic spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR).

A new mechanism by which an acute type B aortic dissection is primarily complicated, becomes complicated, or remains uncomplicated

This study is to evaluate if different locations of the primary entry tear result in primary complicated, secondary complicated, or uncomplicated acute type B aortic dissection.

Influence of temperature management on neurocognitive function in biological aortic valve replacement. A prospective randomized trial

Aim of this study was to elucidate if postoperative neurocognitive function after biological aortic valve replacement (AVR) can be influenced by temperature management during cardiopulmonary bypass (CPB).

Dads, Daughters, And Disney: The Historical Trajectory Of Fairy Tale Fathers And Daughters

In my thesis I use a historical approach to close readings of fairy tale texts and movies to study the evolution of fathers, daughters, and marriage within three landmark tales: ¿Cinderella,¿ ¿Sleeping Beauty,¿ and ¿Snow White.¿ Using the works of Giambattista Basile, Charles Perrault, Jacob and Wilhelm Grimm, and Walt Disney and his cohort of animators, I trace the historical trajectory of these three elements, analyzing both the ways they change and develop as history progresses as well as the ways they remain consistent. Through close and comparative readings of primary sources and films, I demonstrate the power structures and familial dynamics evident through the interactions of fathers and daughters. Specifically, I show that through the weakness and ineptitude of fairy tale fathers, fairy tale daughters are able to gain power, authority, and autonomy by using magic and marriage to navigate patriarchal systems. The work I have done is important because it explores how each tale is a product of the story before it and thus that in order for these tales to continue to survive the test of time, we must not only recognize the validity of the academic merit of the Disney stories, but also remember them and others as we forge new paths in the stories we use to teach both children and parents. Specifically, this work is important because it explores the historical trend evident in the evolving relationships between fathers and daughters. This relationship ultimately it reveals the deep underlying need for family within all of us.

Characterization of the bovine IkappaB kinases (IKK)alpha and IKKbeta, the regulatory subunit NEMO and their substrate IkappaBalpha

The Nuclear factor (NF)-kappaB signalling pathway plays a critical role in the regulation and coordination of a wide range of cellular events such as cell growth, apoptosis and cell differentiation. Activation of the IKK (inhibitor of NF-kappaB kinase) complex is a crucial step and a point of convergence of all known NF-kappaB signalling pathways. To analyse bovine IKKalpha (IKK1), IKKbeta (IKK2) and IKKgamma (or NF-kappaB Essential MOdulator, NEMO) and their substrate IkappaBalpha (Inhibitor of NF-kappaB), the corresponding cDNAs of these molecules were isolated, sequenced and characterized. A comparison of the amino acid sequences with those of their orthologues in other species showed a very high degree of identity, suggesting that the IKK complex and its substrate IkappaBalpha are evolutionarily highly conserved components of the NF-kappaB pathway. Bovine IKKalpha and IKKbeta are related protein kinases showing 50% identity which is especially prominent in the kinase and leucine zipper domains. Co-immunoprecipitation assays and GST-pull-down experiments were carried out to determine the composition of bovine IKK complexes compared to that in human Jurkat T cells. Using these approaches, the presence of bovine IKK complexes harbouring IKKalpha, IKKbeta, NEMO and the interaction of IKK with its substrate IkappaBalpha could be demonstrated. Parallel experiments using human Jurkat T cells confirmed the high degree of conservation also at the level of protein-protein interactions. Finally, a yeast two-hybrid analysis showed that bovine NEMO molecules, in addition to the binding to IKKalpha and IKKbeta, also strongly interact with each other.

Coprological study on intestinal helminths in Swiss dogs: temporal aspects of anthelminthic treatment

Coproscopic examination of 505 dogs originating from the western or central part of Switzerland revealed the presence (prevalence data) of the following helminthes: Toxocara canis (7.1%), hookworms (6.9%), Trichuris vulpis (5.5%), Toxascaris leonina (1.3%), Taeniidae (1.3%), Capillaria spp. (0.8%), and Diphyllobothrium latum (0.4%). Potential risk factors for infection were identified by a questionnaire: dogs from rural areas significantly more often had hookworms and taeniid eggs in their feces when compared to urban family dogs. Access to small rodents, offal, and carrion was identified as risk factor for hookworm and Taeniidae, while feeding of fresh and uncooked meat did not result in higher prevalences for these helminths. A group of 111 dogs was treated every 3 months with a combined medication of pyrantel embonate, praziquantel, and febantel, and fecal samples were collected for coproscopy in monthly intervals. Despite treatment, the yearly incidence of T. canis was 32%, while hookworms, T. vulpis, Capillaria spp., and Taeniidae reached incidences ranging from 11 to 22%. Fifty-seven percent of the 111 dogs had helminth eggs in their feces at least once during the 1-year study period. This finding implicates that an infection risk with potential zoonotic pathogens cannot be ruled out for the dog owner despite regular deworming four times a year.
