Metaparametric Neurological Networks with regard to Emergency Examination.
We report the synthesis of two new acyclic sulfated acyclic CB[n]-type receptors ( TriM0 and Me 4 TetM0 ) and investigations of their binding properties toward a panel of drugs of abuse ( 1 - 13 ) by a combination of 1 H NMR spectroscopy and isothermal titration calorimetry. TetM0 is the most potent receptor with K a ≥ 10 6 M -1 toward methamphetamine, fentanyl, MDMA and mephedrone. TetM0 is not cytotoxic toward HepG2 and HEK 293 cells below 100 m M according to MTS metabolic and adenylate kinase release assays and is well tolerated in vivo when dosed at 46 mg kg -1 . TetM0 does not inhibit the hERG ion channel and is not mutagenic based on the Ames fluctuation test. Finally, in vivo efficacy studies show that the hyperlocomotion of mice treated with methamphetamine can be greatly reduced by treatment with TetM0 up to 5 minutes later. TetM0 has potential as a broad spectrum in vivo sequestrant for drugs of abuse.Xylo-oligosaccharide (XOS), which is considered as a potential prebiotic, exhibits multiple beneficial effects on modulation of gut microbiota, strength of intestinal barrier, and inhibition of intestinal inflammation. The objective of this study is to investigate whether XOS protects against Salmonella infection by modulating gut microbiota, enhancing the intestinal barrier, and resisting colonization. C57BL/6 male mice received water supplementation with 5% XOS for 14 days before Salmonella Typhimurium infection. The results showed that XOS suppressed the Salmonella-induced inflammation, but had limited effects on tight junction molecules and mRNA expression of mucus proteins, except for claudin-1 in the colon. Data of 16S rDNA sequencing indicated that XOS modulated gut microbiota composition by significantly stimulating Bifidobacterium animalis (B. animalis), and reducing Salmonella counts. Therefore, the potential protective effects of B. animalis against Salmonella challenge were investigated as well.

However, current ECDs typically suffer from low coloration efficiency (CE) and high energy consumption, which have thus hindered their practical applications, especially as components in solar-powered EC windows. Here, the high-performance ECDs with a fully crystalline viologen-immobilized 2D polymer (V2DP) thin film as the color-switching layer is demonstrated. The high density of vertically oriented pore channels (pore size ≈ 4.5 nm; pore density ≈ 5.8 × 1016 m-2 ) in the synthetic V2DP film enables high utilization of redox-active viologen moieties and benefits for Li+ ion diffusion/transport. As a result, the as-fabricated ECDs achieve a rapid switching speed (coloration, 2.8 s; bleaching, 1.2 s), and a high CE (989 cm2 C-1 ), and low energy consumption (21.1 µW cm-2 ). Moreover, it is managed to fabricate transmission-tunable, self-sustainable EC window prototypes by vertically integrating the V2DP ECDs with transparent solar cells. This work sheds light on designing electroactive 2D polymers with molecular precision for optoelectronics and paves a practical route toward developing self-powered EC windows to offset the electricity consumption of buildings.Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders characterized by relapsing intestinal inflammation, but many details of pathogenesis remain to be fully unraveled. Glucocorticoid (GC)-induced leucine zipper (GILZ) is a mediator of the anti-inflammatory effects of GCs, the most powerful drugs for IBD treatment, but they cause several unwanted side effects. The fusion protein TAT-GILZ has been successfully used in some pre-clinical models of inflammatory and autoimmune diseases. To test the efficacy of TAT-GILZ for treating dextran sulfate sodium (DSS)-induced colitis and explore its impact on the gut microbiome, colitis was induced by DSS in C57BL/6J mice and treated with TAT-GILZ or dexamethasone. Various hallmarks of colitis were analyzed, including disease activity index, gut permeability, and expression of pro-inflammatory cytokines and tight junction proteins. TAT-GILZ treatment showed a therapeutic effect when administered after the onset of colitis. Its efficacy was associated with improved gut permeability, as evidenced by zonula occludens-1 and CD74 upregulation in inflamed colonic tissue. TAT-GILZ also ameliorated the changes in the gut microbiota induced by the DSS, thus potentially providing an optimal environment for colonization of the mucosa surface by beneficial bacteria. Overall, our results demonstrated for the first time that TAT-GILZ treatment proved effective after disease onset allowing restoration of gut permeability, a key pathogenic feature of colitis. Additionally, TAT-GILZ restored gut dysbiosis, thereby contributing to healing mechanisms. Interestingly, we found unprecedented effects of exogenous GILZ that did not overlap with those of GCs.Integrated aquatic systems are used to decrease the nutrient loads of effluents negating the negative environmental impacts of aquacultural systems. Some of these systems have a separate algae compartment requiring high maintenance. An integrated culture system was set up with different trophic levels algae, zooplankton and fish. The algal tank was in-line with the fish and zooplankton components to minimise the maintenance required for the algae. A control flow-through system was also set up without the algae and zooplankton compartments. The systems were run for 6 wk and water temperature, pH, dissolved oxygen, NO3 , NO2 , NH4 and PO4 concentrations were measured. A removal rate was determined for each water parameter and the densities of the algae and zooplankton species were measured in each compartment of the integrated system. The concentrations of most nutrients in the integrated system were similar to those of the control system. The density of algae increased during the first three wk and remained almost stable until the end of the experiment. There was an inverse relationship between the densities of two zooplankton suggesting compensatory effects on the control of the algal bloom. The integrated system improved water quality with minimal algal culture maintenance, water exchange and no fish mortality.
Ischemic heart disease is the leading cause of death around the world. Coronary artery bypass grafting offers efficient surgical revascularization for ischemic disease. Both on- or off-pump coronary artery bypass methods provide promising results to octogenarians, once complete vascularization is achieved. However, off-pump bypass requires a certain level of experience to achieve sufficient results. We have applied an off-pump coronary artery bypass-first strategy to all generations since 2008. This study investigated early and long-term results of surgical revascularization for octogenarians by a team with an off-pump-first strategy.

All cases of isolated coronary artery bypass grafting performed since 2008 were identified and divided into a young group (age < 80 years) and an old group (age ≥ 80 years). Peri-operative results were investigated retrospectively in both groups and long-term results for the old group were assessed.

Among the 707 patients, 97% underwent off-pump bypass, and 94 cases were classified to the old group. Distal anastomoses and ventilator time were identical between groups (young vs. old 3.3 vs. 3.2; 3.7 h vs. 3.7 h). In-hospital death rates were 0.5% and 0% in the young and old groups, respectively. With a mean follow-up of 1318 days, actual 1-, 3-, and 5-year survival rates for octogenarians were 92.1%, 81.2%, and 68.3%, respectively. Nearly half of the patients reached their nineties, which was close to the life expectancy of the national general octogenarian.

An experienced team with an off-pump-first strategy could provide valid therapeutic options for octogenarians.

RuZ could self-assemble into nanoaggregates in the cell culture medium and resulted in a high intracellular concentration of RuZ in MDR cancer cells. The self-assembly significantly decreased oxygen consumption and inhibited glycolysis, which decreased cellular ATP levels. The reduction in ATP levels and its low affinity for the ABCB1 and ABCG2 transporters (which mediate MDR) significantly increased the retention of RuZ by MDR cancer cells. Furthermore, RuZ increased cellular oxidative stress, inducing DNA damage, and in combination with the aforementioned effects of RuZ, increased the apoptosis of cancer cells. Proteomic profiling analysis suggested that the RuZ primarily decreased the expression of proteins that mediate glycolysis and aerobic mitochondrial respiration and increased the expression of proteins involved in apoptosis. RuZ inhibited the proliferation of 35 cancer cell lines, of which 7 cell lines were resistant to clinical drugs. It was also active in doxorubicin-resistant MDA-MB-231/Adr mouse tumor xenograft. To the best of our knowledge, our results are the first to show that self-assembled cycloruthenated complexes are efficacious in inhibiting the growth of MDR cancer cells.

The compounds form two isotypic series of 3D-coordination polymers and exhibit fair thermal stability up to 360 °C. The luminescence properties of all ten compounds were determined in the solid-state, with an antenna effect through ligand-metal energy transfer leading to high efficiency of the luminescence displayed by good quantum yields up to 74%. The emission is mainly based on ion specific lanthanide-dependent intra 4f-4f-transitions for Tb 3+ green, Dy 3+ yellow, Sm 3+ orange-red, Eu 3+ red. For the Gd 3+ containing compounds, yellow emission of ligand triplet-based phosphorescence is observed at room temperature and 77 K. Co-doping of the Gd-containing frameworks with Eu 3+ and Tb 3+ allow further shifting of the chromaticity towards white light emission.The electrophilic fluorination of geminal alkyl substituted vinyl-Bmida derivatives proceeds via bora-Wagner-Meerwein rearrangement. According to DFT modelling studies this rearrangement occurs with a low activation barrier via a bora-cyclopropane shaped TS. The Bmida group has a larger migration aptitude than the alkyl moiety in the Wagner-Meerwein rearrangement of the presented electrophilic fluorination reactions.Proteolytic ectodomain shedding of membrane proteins is a fundamental mechanism to control the communication between cells and their environment. A key protease for membrane protein shedding is ADAM17, which requires a non-proteolytic subunit, either inactive Rhomboid 1 (iRhom1) or iRhom2 for its activity. While iRhom1 and iRhom2 are co-expressed in most tissues and appear to have largely redundant functions, the brain is an organ with predominant expression of iRhom1. Yet, little is known about the spatio-temporal expression of iRhom1 in mammalian brain and about its function in controlling membrane protein shedding in the nervous system. Here, we demonstrate that iRhom1 is expressed in mouse brain from the prenatal stage to adulthood with a peak in early postnatal development. In the adult mouse brain iRhom1 was widely expressed, including in cortex, hippocampus, olfactory bulb, and cerebellum. Proteomic analysis of the secretome of primary neurons using the hiSPECS method and of cerebrospinal fluid, obtained from iRhom1-deficient and control mice, identified several membrane proteins that require iRhom1 for their shedding in vitro or in vivo.
