Bioelectrocatalysis thus offers an approach to enzyme simplification as a remedy for the inherent instability of self-sufficient cytochrome P450 enzymes. In addition, we examined native and artificial enzyme activation with respect to ionic strength and buffer composition. The optimal conditions of the activation types differ substantially from each other and exhibit a new molecular facet in enzyme characteristics. In a proof-of-principle we demonstrate that the platform is also compatible with raw cell extracts, thus opening the door for random mutagenesis screenings.Rheumatoid arthritis is a chronic, systemic joint disease in which an autoimmune response translates into an inflammatory attack resulting in joint damage, disability and decreased quality of life. Despite recent introduction of therapeutic agents such as anti-TNFα, even the best current therapies fail to achieve disease remission in most arthritis patients. Therefore, research into the mechanisms governing the destructive inflammatory process in rheumatoid arthritis is of great importance and may reveal novel strategies for the therapeutic interventions. To gain deeper insight into its pathogensis, we have developed for the first time a three-dimensional synovium-on-a-chip system in order to monitor the onset and progression of inflammatory synovial tissue responses. In our study, patient-derived primary synovial organoids are cultivated on a single chip platform containing embedded organic-photodetector arrays for over a week in the absence and presence of tumor-necrosis-factor. Using a label-free and non-invasive optical light-scatter biosensing strategy inflammation-induced 3D tissue-level architectural changes were already detected after two days. We demonstrate that the integration of complex human synovial organ cultures in a lab-on-a-chip provides reproducible and reliable information on how systemic stress factors affect synovial tissue architectures.The reactions of two equivalents of germylene [(i-Pr)2NB(N-2,6-Me2C6H3)2]Ge (1) with carbonyl compounds RC(O)R' resulted in carbonyl functionality activation and the formation of 4-(R,R')-1,2-digerma-3-oxa-cyclobutanes (R/R' = Ph/CF3 (2) or C6F5/H (3)). Surprisingly, the analogous reaction of 1 with C6F5C(O)Me led to the insertion of the germanium atom into the C-F bond of the perfluorophenyl group, thus producing a spiro compound (4) with a germanium atom sharing 1,2-digerma-3,5-diaza-4-bora-cyclopentane and 1-germa-2,4-diaza-3-boracyclobutane rings. Furthermore, the reaction of 1 with 2e- donors was investigated. In the case of 4-dimethylaminopyridine (DMAP), an expected complex [(i-Pr)2NB(N-2,6-Me2C6H3)2]Ge(DMAP) (5) was isolated, but using t-BuNC resulted in the formation of germanium(iv) cyanide [(i-Pr)2NB(N-2,6-Me2C6H3)2]Ge(CN)(t-Bu) (6) as a result of C-N bond activation in the starting isocyanide. In contrast, mixing other isocyanides RNC (R = Cy or Ad) with 1 in solution led only to an equilibrium between the starting compounds and most probably the corresponding complexes [(i-Pr)2NB(N-2,6-Me2C6H3)2]Ge(CNR) (R = Cy (7a) or Ad (8a)) based on NMR studies. From these equilibrium mixtures, fortuitously, single crystals of digerma-spiro-complexes (7 and 8) containing two germanium atoms (one of them coordinated to a particular isocyanide) were obtained and structurally authenticated by the X-ray diffraction technique.Diarrheagenic Escherichia coli as an enteropathogen has caused serious public safety problems, especially in children. A fast, easy-to-use, high-throughput method is urgently needed for diarrheagenic Escherichia coli strain identification and monitoring. In this study, we developed a portable microfluidic device based on circular fluorescent probe-mediated isothermal nucleic acid amplification for accurate and rapid detection of twelve virulence factor genes of five diarrheagenic Escherichia coli strains for point-of-care testing. This microfluidic system showed excellent performance in identifying five diarrheagenic Escherichia coli strains within 60 min, when applied in 67 clinical samples collected from hospitals for identifying diarrheagenic Escherichia coli, with a good clinical sensitivity (96.9%), specificity (97.1%) and stability (CV less then 5.0%). This integrated microfluidic system is a promising diagnostic tool for applications in the identification and monitoring of diarrheagenic Escherichia coli epidemics worldwide, particularly in developing countries.Transcription factors (TFs) play critical roles in gene expression regulation and disease development. In this paper, we report an antibody free ELISA-like assay which could be used to analyze transcription factor NF-κB p50 with comparatively low cost and high throughput. selleck chemicals This assay is based on the stabilization of a duplex DNA probe by binding with a transcription factor. The double-stranded DNA (dsDNA) probe immobilized on a 96-well plate was too short in length to stabilize its duplex structure at a relatively high temperature and would unwind into a single strand. In the presence of a target TF, the protein bound to a specific TF-binding site and prevented the specific dsDNA probe from being unzipped at the washing temperature, thus holding the chemiluminescence signal. This method could sensitively detect NF-κB p50 with a detection limit of 0.5 nM. The proposed strategy provides a convenient, cheap and high throughput detection method of TFs, which can potentially help the development of drug discovery and disease diagnosis.Understanding how electrons and protons move in a coupled manner and affect one another is important to the design of proton-electron conductors and achieving biological transport in synthetic materials. In this study, a new methodology is proposed that allows for the quantification of the degree of coupling between electrons and protons in tyrosine-rich peptides and metal oxide hybrid films at room temperature under a voltage bias. This approach is developed according to the Onsager principle, which has been thoroughly established for the investigation of mixed ion-electron conductors with electron and oxide ion vacancies as carriers at high temperatures. Herein, a new device platform using electron-blocking electrodes provides a new strategy to investigate the coupling of protons and electrons in bulk materials beyond the molecular level investigation of coupled proton and electron transfer. Two Onsager transport parameters, αi* and σe', are obtained from the device, and the results of these transport parameters demonstrate that the coupled transport of electrons and protons inside the hybrid film plays an important role in the macroscopic-scale conduction.
