The cell-wall peptidoglycan contained meso-diaminopimelic acid (which is a diagnostic cell-wall diamino acid), alanine and glutamic acid. The respiratory quinones was found to be menaquinone-8. The DNA G+C content of strain DD2AT was 74.8 mol%. On the basis of the findings of genotypic, phenotypic, chemotaxonomic and phylogenetic analyses, strain DD2AT was considered to represent a novel member in the genus Quadrisphaera, for which the name Quadrisphaera setariae sp. nov. is proposed. The type strain of Quadrisphaera setariae is DD2AT (=KACC 21165T=NBRC 113770T).Emerging contaminants are of concern due to their rapidly increasing numbers and potential ecological and human health effects. In this study, the synergistic effects of the presence of multifunctional nitro, amino and carbon-carbon double bond (C═C) groups on the gas phase ozonolysis in O2 or at the air/solid interface were investigated using five simple model compounds. The gas phase ozonolysis rate constants at 296 K were (3.5 ± 0.9) × 10-20 cm3 molecule-1 s-1 for 2-methyl-1-nitroprop-1-ene and (6.8 ± 0.8) × 10-19 cm3 molecule-1 s-1 for 4-methyl-4-nitro-1-pentene, with lifetimes of 134 and 7 days in the presence of 100 ppb ozone in the atmosphere, respectively. The rate constants for gas phase E-N,N-dimethyl-1-propenylamine and N,N-dimethylallylamine reactions with ozone were too fast (>10-18 cm3 molecule-1 s-1) to be measured, implying lifetimes of less than 5 days. A multiphase kinetics model (KM-GAP) was used to probe the gas-solid kinetics of 1-dimethylamino-2-nitroethylene, yielding a rate constant for the surface reaction of 1.8 × 10-9 cm2 molecule-1 s-1 and in the bulk 1× 10-16 cm3 molecule-1 s-1. These results show that a nitro group attached to the C═C lowers the gas phase rate constant by 2-3 orders of magnitude compared to the simple alkenes, while amino groups have the opposite effect. The presence of both groups provides counterbalancing effects. Products with deleterious health effects including dimethylformamide and formaldehyde were identified by FTIR. The identified products differentiate whether the initial site of ozone attack is C═C and/or the amino group. This study provides a basis for predicting the environmental fates of emerging contaminants and shows that both the toxicity of both the parent compounds and the products should be taken into account in assessing their environmental impacts.Direct air capture (DAC) aims to remove CO2 directly from the atmosphere. In this study, we have demonstrated proof-of-concept of a DAC process combining CO2 adsorption in a packed bed of amine-functionalized anion exchange resins (AERs) with a pH swing regeneration using an electrochemical cell (EC). The resin bed was regenerated using the alkaline solution produced in the cathodic compartment of the EC, while high purity CO2 (>95%) was desorbed in the acidifying compartment. After regenerating the AERs, some alkaline solution remained on the surface of the resins and provided additional CO2 capture capacity during adsorption. The highest CO2 capture capacity measured was 1.76 mmol·g-1 dry resins. Moreover, as the whole process was operated at room temperature, the resins did not show any apparent degradation after 150 cycles of adsorption-desorption. Furthermore, when the relative humidity of the air source increased from 33 to 84%, the water loss of the process decreased by 63%, while CO2 capture capacity fell 22%. Finally, although the pressure drop of the adsorption column (5 ± 1 kPa) and the energy consumption of the EC (537 ± 33 kJ·mol-1 at 20 mA·cm-2) are high, we have discussed the potential improvements toward a successful upscaling.Mechanical strain, such as stretching, compression, bending, and rotation, significantly alters the photonic and electronic properties of 2D materials. The laser shock process, which allows 2D materials to deform at an ultrahigh strain rate, is a promising technology for alleviating the low strain transfer efficiency caused by the low interfacial bonding strength of the layered 2D materials. However, the mechanical strain introduced by shock waves is currently limited to uniaxial compression or bending deformation, and the monotonic strain patterns constrain the strain diversity and performance expansion space of 2D materials. This work proposed a novel strategy for nano-twist manufacturing using laser shock processing, based on partial interfacial decoupling behavior. Apart from the conventional uniaxial strain, we demonstrated experimentally and theoretically that the manufacturing of nano-twist allows the introduction of interlayer tensile and rotational strains in TMDCs. The microstructure and properties of the strained 2D materials were investigated. Furthermore, the dynamic deformation response of WSe2 during the shock process was studied using molecular dynamics simulations. The correlation between the laser shock-induced dynamic loading process, interfacial behavior, and deformation behavior of 2D materials was comprehensively explored. The primary contribution of this study lies in the introduction of diversified strain modes through nano-twist manufacturing by the laser shock process, which is expected to provide a convenient nano-twist fabrication process for the strain engineering and twistronics fields.There has been emerging interest in the exploitation of the photophysical and photochemical properties of transition metal complexes for diagnostic and therapeutic applications. In this Perspective, we highlight the major recent advances in the development of luminescent and photofunctional transition metal complexes, in particular, those of rhenium(I), ruthenium(II), osmium(II), iridium(III), and platinum(II), as bioimaging reagents and phototherapeutic agents, with a focus on the molecular design strategies that harness and modulate the interesting photophysical and photochemical behavior of the complexes. We also discuss the current challenges and future outlook of transition metal complexes for both fundamental research and clinical applications.A new Dethiosulfovibrio strain, designated F2BT, was isolated from an anaerobic digester for treating solid waste from a marine recirculating aquaculture system. The motile, Gram-negative, non-spore-forming curved rods were 2-7 µm long and 1 µm in diameter. Growth occurred at temperatures ranging from 20 to 40 °C with a maximum rate of growth at 30 °C. The pH range for growth was pH 6.0-8.0, with a maximum rate of growth at pH 7.5. This isolate was halotolerant growing in NaCl concentrations ranging from 0 to 1.6 M with a maximum rate of growth at 0.4 M. Similarly to the five described Dethiosulfovibrio species, this obligate anaerobe isolate was fermentative, capable of utilizing peptides, amino acids and some organic acids for growth, but unlike described strains in the genus did not reduce thiosulphate or elemental sulphur to hydrogen sulphide during fermentation of organic substrates. The G+C content of 55 mol% is similar to the described Dethiosulfovibrio species. The average nucleotide identity analysis between whole genome sequences showed less than 93.15% sequence similarity between strain F2BT and the five other described Dethiosulfovibrio species. Differences in the physiological and phylogenetic characteristics between the new strain and other Dethiosulfovibrio specied indicate that F2BT represents a novel species of this genus and the epithet Dethiosulfovibrio faecalis sp. nov. is proposed. The type strain is F2BT (=DSM 112078T=KCTC25378T).Simultaneous monitoring of the ATP levels at various sites of a single cell is crucial for revealing the ATP-related processes and diseases. In this work, we rationally fabricated single nanowire-based fluorescence biosensors, by which the ATP levels of the cytoplasm and nucleus in a single cell can be simultaneously monitored with a high spatial resolution. Utilizing the as-fabricated single nanowire biosensor, we demonstrated that the ATP levels of the cytoplasm were around 20-30% lower than that of the nucleus in both L929 and HeLa cells. Observing the ATP fluctuation of the cytoplasm and nucleus of the L929 and HeLa cells stimulated by Ca2+, oligomycin, or under cisplatin-induced apoptosis, we found that the ATP levels at two cellular sites exhibited discriminative changes, revealing the different mechanisms of the ATP at these two cellular sites in response to the stimulations.Drugs are often removed from clinical trials or market progression owing to their unforeseen effects on cardiac action potential and calcium handling. Induced pluripotent stem cell-derived cardiomyocytes and tissues fabricated from these cells are promising as screening tools for early identification of these potential cardiac liabilities. In this study, we describe an automated, open-source MATLAB-based analysis software for calculating cardiac action potentials and calcium transients from fluorescent reporters. WH-4-023 We first identified the most robust manner in which to automatically identify the initiation point for action potentials and calcium transients in a user-independent manner, and used this approach to quantify the duration and morphology of these signals. We then demonstrate the software by assessing changes to action potentials and calcium transients in our micro-heart muscles after exposure to hydroxychloroquine, an antimalarial drug with known cardiac liability. Consistent with clinical observations, our system predicted mild action potential prolongation. However, we also observed marked calcium transient suppression, highlighting the advantage of testing multiple physiologic readouts in cardiomyocytes rather than relying on heterologous overexpression of single channels such as the human ether-a-go-go-related gene channel. This open-source software can serve as a useful, high-throughput tool for analyzing cardiomyocyte physiology from fluorescence imaging.Underreporting of infectious diseases is a pervasive challenge in public health that has emerged as a central issue in characterizing the dynamics of the COVID-19 pandemic. Infectious diseases are underreported for a range of reasons, including mild or asymptomatic infections, weak public health infrastructure, and government censorship. In this study, we investigated factors associated with cross-country and cross-pathogen variation in reporting. We performed a literature search to collect estimates of empirical reporting rates, calculated as the number of cases reported divided by the estimated number of true cases. This literature search yielded a dataset of reporting rates for 32 pathogens, representing 52 countries. We combined epidemiological and social science theory to identify factors specific to pathogens, country health systems, and politics that could influence empirical reporting rates. We performed generalized linear regression to test the relationship between the pathogen- and country-specific isease statistics, particularly when outbreak-specific empirical estimates of underreporting are unavailable. More precise estimates can inform control policies and improve the accuracy of infectious disease models.Blockade of the PD-L1/PD-1 pathway has proven to be a broadly effective cancer immunotherapy. FDA-approved therapeutic monoclonal antibodies (mAbs) targeting the pathway have high affinity, blocking capacity, and low antibody effector activity. A number of rat antimouse mAbs have been used to model cancer immunotherapy in mouse models. We set forth the amino acid sequences of mAbs specific for mouse PD-1 (29F.1A12) and PD-L1 (10F.9G2) and compare their avidities, blocking capacities, biological activities, and epitope recognition with other commonly used mAbs. Further manipulation of these sequences should facilitate better modeling of immunotherapy in mouse models and the generation of novel agents.
