Für einen Angewandten Utopismus

Utopien beschreiben andere Verhältnisse, um reale Gesellschaften zu kritisieren oder Alternativen zu ihnen zu entwerfen. Sie können ernst sein oder spielerisch. Alle Formen und Realitätsbezüge des Utopischen haben ihren Ort. Aber wir möchten für eine bestimmte Spielart plädieren: Angewandten Utopismus

Comparison of the VetGate and SurgiGATE 1.0 computer assisted surgery systems for insertion of cortex screws across the distal phalanx in horses – an in vitro study

The In vitro experimental study on five cadaveric equine limb pairs (n=10) was conducted to evaluate the functionality and precision of the VetGate Computer Assisted Surgery (CAS) system during insertion of two 4.5mm cortex screws across virtual midsagittal fractures of the distal phalanx (P3) in the horse and to compare the results with those achieved with the SurgiGate 1.0 CAS-System in a similar study. In each specimen wo 4.5mm cortex screws were inserted computer assisted in lag fashion facilitated by the VetGate CASSystem. In none of the specimens did screw penetration of the articular- or solar surface or the semilunar canal, occur. The difference between optimal and actual screw length is significantly better in this study compared to a similar study conducted with the SurgiGATE 1.0 CAS-System. The results achieved with the VetGate CAS-System are even more precise than with the SurgiGATE 1.0 CAS-System (p<0.001). The VetGate CAS-System allows exact screw placement at delicate locations

Phenotypic Adaptation to Antiseptics and Effects on Biofilm Formation Capacity and Antibiotic Resistance in Clinical Isolates of Early Colonizers in Dental Plaque

Despite the wide-spread use of antiseptics in dental practice and oral care products, there is little public awareness of potential risks associated with antiseptic resistance and potentially concomitant cross-resistance. Therefore, the aim of this study was to investigate potential phenotypic adaptation in 177 clinical isolates of early colonizers of dental plaque (Streptococcus, Actinomyces, Rothia and Veillonella spp.) upon repeated exposure to subinhibitory concentrations of chlorhexidine digluconate (CHX) or cetylpyridinium chloride (CPC) over 10 passages using a modified microdilution method. Stability of phenotypic adaptation was re-evaluated after culture in antiseptic-free nutrient broth for 24 or 72 h. Strains showing 8-fold minimal inhibitory concentration (MIC)-increase were further examined regarding their biofilm formation capacity, phenotypic antibiotic resistance and presence of antibiotic resistance genes (ARGs). Eight-fold MIC-increases to CHX were detected in four Streptococcus isolates. These strains mostly exhibited significantly increased biofilm formation capacity compared to their respective wild-type strains. Phenotypic antibiotic resistance was detected to tetracycline and erythromycin, consistent with the detected ARGs. In conclusion, this study shows that clinical isolates of early colonizers of dental plaque can phenotypically adapt toward antiseptics such as CHX upon repeated exposure. The underlying mechanisms at genomic and transcriptomic levels need to be investigated in future studie

Deutschland auf dem Weg zur Klimaneutralität 2045 - Szenarien und Pfade im Modellvergleich (Zusammenfassung)

Erstmals stellt die vorliegende Szenarienanalyse für Deutschland konkreteTransformationspfade zur Klimaneutralität 2045 auf der Basis eines umfassenden Modellvergleichs vor. Das Besondere an dieser Studie des Ariadne-Projektes ist, dass sechs Gesamtsystem- und Sek-tormodelle in einer Studie integriert wurden, die sich in ihren jeweiligen Stärken ergänzen: Für spezifische Fragestellungen wurde jeweils dasjenige Modell als Leitmodell hervorgehoben, welches die entsprechenden Aspekte am genauesten abbildet. Weitere Modelle wurden genutzt, um Auswirkungen der Transformation auf Umweltschutzgüter und die Verteilung der Kosten auf verschiedene Einkommensgruppen zu analysieren.Dieser breit gefächerte Ansatz ermöglicht es, die Implikationen der Energiewende robust und im Detail zu beschreiben

Bauen in Brasilien

Im Herbst 2014 fand die große Exkursion 2014 der Fakultät Bauingenieurwesen der HTWG Konstanz nach Brasilien unter der Leitung von Prof. Dr. Horst Werkle und Prof. Dr. Peter Hirschmann statt. Auf dem Programm stand der Besuch der Städte Sao Paulo, Rio de Janeiro und Iguacu. Der Bericht schildert den Besuch interessanter Baustellen und großer Bauprojekte wie des im Bau befindlichen futuristisch anmutenden „Museum of Tomorrow“, des Maracana-Stadions mit seiner neuen Membrandachkonstruktion sowie des zweitgrößten Wasserkraftwerks der Welt

Consensus on the reporting and experimental design of clinical and cognitive-behavioural neurofeedback studies (CRED-nf checklist)

Exome-Derived Adiponectin-Associated Variants Implicate Obesity and Lipid Biology

Circulating levels of adiponectin, an adipocyte-secreted protein associated with cardiovascular and metabolic risk, are highly heritable. To gain insights into the biology that regulates adiponectin levels, we performed an exome array meta-analysis of 265,780 genetic variants in 67,739 individuals of European, Hispanic, African American, and East Asian ancestry. We identified 20 loci associated with adiponectin, including 11 that had been reported previously (p .60) spanning as much as 900 kb. To identify potential genes and mechanisms through which the previously unreported association signals act to affect adiponectin levels, we assessed cross-trait associations, expression quantitative trait loci in subcutaneous adipose, and biological pathways of nearby genes. Eight of the nine loci were also associated (p <1 x 10(-4)) with at least one obesity or lipid trait. Candidate genes include PRKAR2A, PTH1R, and HDAC9, which have been suggested to play roles in adipocyte differentiation or bone marrow adipose tissue. Taken together, these findings provide further insights into the processes that influence circulating adiponectin levels.Peer reviewe

Highlights From the Annual Meeting of the American Epilepsy Society 2022

With more than 6000 attendees between in-person and virtual offerings, the American Epilepsy Society Meeting 2022 in Nashville, felt as busy as in prepandemic times. An ever-growing number of physicians, scientists, and allied health professionals gathered to learn a variety of topics about epilepsy. The program was carefully tailored to meet the needs of professionals with different interests and career stages. This article summarizes the different symposia presented at the meeting. Basic science lectures addressed the primary elements of seizure generation and pathophysiology of epilepsy in different disease states. Scientists congregated to learn about anti-seizure medications, mechanisms of action, and new tools to treat epilepsy including surgery and neurostimulation. Some symposia were also dedicated to discuss epilepsy comorbidities and practical issues regarding epilepsy care. An increasing number of patient advocates discussing their stories were intertwined within scientific activities. Many smaller group sessions targeted more specific topics to encourage member participation, including Special Interest Groups, Investigator, and Skills Workshops. Special lectures included the renown Hoyer and Lombroso, an ILAE/IBE joint session, a spotlight on the impact of Dobbs v. Jackson on reproductive health in epilepsy, and a joint session with the NAEC on coding and reimbursement policies. The hot topics symposium was focused on traumatic brain injury and post-traumatic epilepsy. A balanced collaboration with the industry allowed presentations of the latest pharmaceutical and engineering advances in satellite symposia

Genetic Studies of Leptin Concentrations Implicate Leptin in the Regulation of Early Adiposity.

Leptin influences food intake by informing the brain about the status of body fat stores. Rare LEP mutations associated with congenital leptin deficiency cause severe early-onset obesity that can be mitigated by administering leptin. However, the role of genetic regulation of leptin in polygenic obesity remains poorly understood. We performed an exome-based analysis in up to 57,232 individuals of diverse ancestries to identify genetic variants that influence adiposity-adjusted leptin concentrations. We identify five novel variants, including four missense variants, in LEP, ZNF800, KLHL31, and ACTL9, and one intergenic variant near KLF14. The missense variant Val94Met (rs17151919) in LEP was common in individuals of African ancestry only, and its association with lower leptin concentrations was specific to this ancestry (P = 2 × 10-16, n = 3,901). Using in vitro analyses, we show that the Met94 allele decreases leptin secretion. We also show that the Met94 allele is associated with higher BMI in young African-ancestry children but not in adults, suggesting that leptin regulates early adiposity
