Photochemical oxidation of phenols and anilines mediated by phenoxyl radicals in aqueous solution

Urs von Gunten, Silvio Canonica, Stephanie Christa Remke

Reactive intermediates formed upon irradiation of chromophoric dissolved organic matter (CDOM) contribute to the degradation of various organic contaminants in surface waters. Besides well-studied "short-lived" photo oxidants, such as triplet state CDOM (3 ...

Mid- and long-term outcome of Salter's, Pemberton's and Dega's osteotomy for treatment of developmental dysplasia of the hip: a systematic review and meta-analysis

Introduction: Early diagnosis and early treatment have become the gold standard for management of developmental dysplasia of the hip. Surgery is required in case of failed initial treatment. Innominate pelvic osteotomy of Salter (SIO), Pemberton's pericaps ...

Modeling biochemical reaction networks in complex intracellular environments

Daniel Robert Weilandt

Whether one aims to design treatments for diseases such as cancer or diabetes, engineer cells to produce valuable biochemicals sustainably, or to grasp the behavior of living organisms, it is essential to understand how cells react to genetic, environmenta ...

The melanization reaction in Drosophila: More than black or white

Jan Paul Dudzic

The melanization reaction is a rapid and important immune mechanism in arthropods. It results in the production of melanin at the site of injury and around invading microbes. The enzymes responsible for melanogenesis are phenoloxidases (PO), which catalyze ...

Seasonality alters drivers of soil enzyme activity in subalpine grassland soil undergoing climate change

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Thomas Spiegelberger, Robert Thomas Edmund Mills

In mountain ecosystems with marked seasonality, climate change can affect various processes in soils, potentially modifying long-term key soil services via change in soil organic carbon (C) storage. Based on a four-year soil transplantation experiment in S ...

Towards artificial methanogenesis: biosynthesis of the [Fe]-hydrogenase cofactor and characterization of the semisynthetic hydrogenase

Xile Hu, Lichen Bai, Tao Xu

The greenhouse gas and energy carrier methane is produced on Earth mainly by methanogenic archaea. In the hydrogenotrophic methanogenic pathway the reduction of one CO2 to one methane molecule requires four molecules of H-2 containing eight electrons. Four ...

Multiple scanning electrochemical microscopy mapping of tyrosinase in micro-contact printed fruit samples on polyvinylidene fluoride membrane

Hubert Girault, Andreas Stephan Lesch, Liang Qiao, Fernando Cortes Salazar, Tzu-En Lin, Alexandra Bondarenko

Herein, we introduce three orthogonal and compatible methods for detecting tyrosinase, a key factor in fruit browning and skin disorders, with high spatial resolution by means of scanning electrochemical microscopy (SECM). All methods are performed subsequ ...

Light availability affects stream biofilm bacterial community composition and function, but not diversity

Tom Ian Battin

Changes in riparian vegetation or water turbidity and browning in streams alter the local light regime with potential implications for stream biofilms and ecosystem functioning. We experimented with biofilms in microcosms grown under a gradient of light in ...

Redefining the metabolic landscape through TGF-beta/Activin signaling in Drosophila melanogaster

Wen Bin Chng

Multicellular organisms assess their nutritional state and adapt their metabolic landscape to match their energy demands. In this thesis, we address a longstanding conundrum of how an organism coordinates digestive enzyme expression in response to its nutr ...

Data, Parameters & Nonlinearities: Development and Applications of Large-scale Dynamic Models of Metabolism

Vassily Hatzimanikatis, Ljubisa Miskovic, Keng Cher Soh, Anirikh Chakrabarti

Dynamic nonlinear models of metabolism offer a significant advantage as compared to constraint-based stoichiometric descriptions. However, progress in the development of large-scale nonlinear models has been hindered by both structural and quantitative unc ...
