TTC staining was applied to reveal the infarct lesions in the brain of dMCAO mice. Results The pro-inflammatory cytokines, TUNEL-positive cells, and p-mTOR were decreased while the anti-inflammatory cytokine, autophagy-related proteins, and p-AMPK were increased in HUMSCs treated with VX-765 under OGD condition. Different expression patterns were found with the above factors after transfection of 3-MA or Compound C. The pro-inflammatory cytokines, TUNEL-positive cells, and infarct sections were decreased while the anti-inflammatory cytokine and autophagy-related proteins were increased in dMCAO mice transplanted with VX-765-treated HUMSCs compared to those transplanted with HUMSCs only. The autophagy was inhibited while p-mTOR was up-regulated after transfection of MHY. Conclusion VX-765 protects HUMSCs against stroke-induced apoptosis and inflammatory responses by activating autophagy via the AMPK/mTOR signaling pathway in vivo and in vitro.CO2 electroreduction by solid oxide electrolysis cells (SOECs) can not only attenuate the greenhouse effect, but also convert surplus electrical energy into chemical energy. The adsorption and activation of CO2 on the cathode play an important role in the SOEC performance. La0.6 Sr0.4 Co0.2 Fe0.8 O3-δ -Ce0.8 Sm0.2 O2-δ (LSCF-SDC; SDC=samarium-doped ceria) is a promising SOEC cathode. However, its electrocatalytic activity still needs to be improved. In this study, Pt/SDC interfaces are constructed by decorating Pt nanoparticles onto the SDC surface. Electrochemical measurements indicate that the polarization resistance of the SOEC is decreased from 0.308 to 0.120 Ω cm2 , and the current density is improved from 0.913 to 1.420 A cm-2 at 1.6 V and 800 °C. Physicochemical characterizations suggest that construction of the Pt/SDC interfaces increases the oxygen vacancy concentration on the cathode and boosts CO2 adsorption and dissociation, which leads to enhanced CO2 electroreduction performance in SOECs.Background The novel coronavirus 2019 (COVID-19) pandemic has changed health care, challenged by resource constraints and fears of transmission. We report the surgical practice pattern changes in a Head and Neck Surgery department of a tertiary cancer care center and discuss the issues surrounding multidisciplinary care during the pandemic. Methods We report data regarding outpatient visits, multidisciplinary treatment planning conference, surgical caseload, and modifications of oncologic therapy during this pandemic and compared this data to the same interval last year. Results We found a 46.7% decrease in outpatient visits and a 46.8% decrease in surgical caseload, compared to 2019. We discuss the factors involved in the decision-making process and perioperative considerations. Conclusions Surgical practice patterns in head and neck oncologic surgery will continue to change with the evolving pandemic. Despite constraints, we strive to prioritize and balance the oncologic and safety needs of patients with head and neck cancer in the face of COVID-19.The objective of this study was to predict the value of lymphocyte subsets in cancer progression. Peripheral blood was obtained from 327 untreated patients with cancer and 158 healthy volunteers. Levels of lymphocyte subsets were determined by flow cytometry. There were decreased levels of natural killer (NK) cells, CD8+ T cells, and naïve CD4+ /CD4+ T cells in untreated patients with cancer compared to those in healthy controls. Inversely, there were elevated levels of the following T-cell percentages in cancer patients compared to those in healthy controls memory CD4+ /CD4+ , CD8+ T cells, HLA-DR/CD8+ , CD8+ CD38+ /CD8+ , and CD4+ /CD8+ . In addition, there are a decreasing trend in terms of CD4+ T-cell counts and an increase CD8+ HLA-DR/CD8+ T-cell and CD8+ CD38+ /CD8+ T-cell percentages in the advanced stage. An increasing trend with advanced tumor stage and the percentages of CD8+ HLA-DR/CD8+ T cells and CD8+ CD38+ /CD8+ T cells was shown in this study. There are a negative correlation for CD4+ T-cell counts and positive correlation for percentages of CD8+ HLA-DR/CD8+ T cell and CD8+ CD38+ /CD8+ T cells with the lymph node metastasis. In the presence of distant metastatic spread, we observed higher NK-cell counts, CD8+ HLA-DR/CD8+ T-cell percentages, CD8+ CD38+ /CD8+ T-cell percentages, as well as lower CD4+ T-cell counts than those in the absence of distant metastases spread. Abnormal levels of NK cell, CD8+ T cells, memory CD4+ /CD4+ , naïve CD4+ / CD4+ , CD8+ HLA-DR/CD8+ , CD8+ CD38+ /CD8+ , and CD4+ /CD8+ can be a potential blood biomarkers of cancer development. CD4+ T-cell counts and percentages of CD8+ HLA-DR/ CD8+ and CD8+ CD38+ / CD8+ can predict the cancer progression.Purpose/objectives Three-dimensional (3D) printing is recognized as an effective clinical and educational tool in procedurally intensive specialties. However, it has a nascent role in radiation oncology. The goal of this investigation is to clarify the extent to which 3D printing applications are currently being used in radiation oncology through a systematic review of the literature. Materials/methods A search protocol was defined according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Included articles were evaluated using parameters of interest including year and country of publication, experimental design, sample size for clinical studies, radiation oncology topic, reported outcomes, and implementation barriers or safety concerns. Results One hundred and three publications from 2012 to 2019 met inclusion criteria. The most commonly described 3D printing applications included quality assurance phantoms (26%), brachytherapy applicators (20%), bolus (17%), preclin nature and the few clinical studies that do exist report on small sample sizes. Further dissemination of ongoing investigations describing the clinical application of developed 3D printing technologies in larger cohorts is warranted.Stochastic multicolor transgenic labeling systems, such as the Brainbow reporters, have emerged as powerful tools in lineage tracing experiments. Originally designed for large-scale mapping of neuronal projections in densely populated tissues, they have been repurposed for diverse uses. The Brainbow 2.1-derived Confetti reporter was used, for example, to define stem cell clonality and dynamics in crypts of the intestinal mucosa, T-cell clonality, microglial heterogeneity, and B-cell clonal evolution in germinal centers. Traditionally, read-outs have relied on imaging in situ, providing information about cellular localization within tissue stroma. However, recent applications of the technique have moved into hematopoietically derived motile cell types, for example, T and B lymphocytes and their progeny, creating an unmet need to survey larger populations of cells ex vivo to determine labeling densities or skews in color representation over time to read-out clonal expansion and selection effects. Originally designed for imaging methods, these reporters encode information in the spectral properties of fluorophores and their subcellular localization, making them poorly suited to traditional flow cytometry analyses. The advent of high-content imaging and imaging flow cytometry have recently closed the gap between flow cytometry and imaging. We analyzed a 10-color biallelic Confetti reporter using flow and imaging flow cytometry. Beyond its use as a high-throughput method for measuring reporter labeling densities and color distributions over time, it also opens the door to new avenues of research relying on similar read-outs, for example, tumor heterogeneity and clonal dynamics. © 2020 International Society for Advancement of Cytometry.Existing date marking tools, such as use-by and sell-by dates, fail to inform decision-making throughout food distribution because they do not adapt to storage conditions such as temperature. Polymer-based sensors can be incorporated into food packaging to provide an indication of food quality in real time, which can greatly reduce waste. This work identifies free fatty acid (FFA) as a marker for the quality of plant-based milk and demonstrates the first detection tool for the freshness of almond milk using phospholipid-doped polydiacetylene (PDA) vesicles. The sensor discriminates between triglycerides and FFA by a visible color change and can therefore be used to track fat metabolism during food spoilage. The interaction between FFA and PDA is investigated by electron microscopy and dynamic-light-scattering studies. PDA vesicles are then fabricated in agarose and used to discriminate between fresh and spoiled almond milk. Upon exposure of the PDA/agarose sensor to spoiled almond milk, a visible blue-to-red color change is induced in the film, which is correlated with FFA concentration in the samples. Incorporation of this technology into food packaging can be used to indicate food quality in real time, surpassing the efficacy of current date marking tools to reduce food waste.Constructing heterostructures with abundant interfaces is essential for integrating the multiple functionalities in single entities. Protokylol nmr Herein, the synthesis of NiSe2 /CoSe2 heterostructures with different interfacial densities via an innovative strategy of successive ion injection is reported. The resulting hybrid electrocatalyst with dense heterointerfaces exhibits superior electrocatalytic properties in an alkaline electrolyte, superior to other benchmarks and precious metal catalysts. Advanced synchrotron techniques, post structural characterizations, and density functional theory (DFT) simulations reveal that the introduction of atomic-level interfaces can lower the oxidation overpotential of bimetallic Ni and Co active sites (whereas Ni2+ can be more easily activated than Co2+ ) and induce the electronic interaction between the core selenides and surface in situ generated oxides/hydroxides, which play a critical role in synergistically reducing energetic barriers and accelerating reaction kinetics for catalyzing the oxygen evolution. Hence, the heterointerface structure facilitates the catalytic performance enhancement via increasing the intrinsic reactivity of metallic atoms and enhancing the synergistic effect between the inner selenides and surface oxidation species. This work not only complements the understanding on the origins of the activity of electrocatalysts based on metal selenides, but also sheds light on further surface and interfacial engineering of advanced hybrid materials.The luminous efficiency of inorganic white light-emitting diodes, to be used by the next generation as light initiators, is continuously progressing and is an emerging interest for researchers. However, low color-rendering index (Ra), high correlated color temperature (CCT), and poor stability limit its wider application. Herein, it is reported that Sm3+ - and Eu3+ -doped calcium scandate (CaSc2 O4 (CSO)) are an emerging deep-red-emitting material with promising light absorption, enhanced emission properties, and excellent thermal stability that make it a promising candidate with potential applications in emission display, solid-state white lighting, and the device performance of perovskite solar cells (PSCs). The average crystal structures of Sm3+ -doped CSO are studied by synchrotron X-ray data that correspond to an extremely rigid host structure. Samarium ion is incorporated as a sensitizer that enhances the emission intensity up to 30%, with a high color purity of 88.9% with a 6% increment. The impacts of hosting the sensitizer are studied by quantifying the lifetime curves.
