Abstract
The prevention of Botrytis cinerea infection and the study of grape seedlessness are very important for grape industries. Finding correlated regulatory genes is an important approach towards understanding their molecular mechanisms. Ethylene responsive factor (ERF) gene family play critical roles in defence networks and the growth of plants. To date, no large-scale study of the ERF proteins associated with pathogen defence and ovule development has been performed in grape (Vitis vinifera L.). In the present study, we identified 113 ERF genes (VvERF) and named them based on their chromosome locations. The ERF genes could be divided into 11 groups based on a multiple sequence alignment and a phylogenetic comparison with homologues from Arabidopsis thaliana. Synteny analysis and Ka/Ks ratio calculation suggested that segmental and tandem duplications contributed to the expansion of the ERF gene family. The evolutionary relationships between the VvERF genes were investigated by exon-intron structure characterisation, and an analysis of the cis-acting regulatory elements in their promoters suggested potential regulation after stress or hormone treatments. Expression profiling after infection with the fungus, B. cinerea, indicated that ERF genes function in responses to pathogen attack. In addition, the expression levels of most ERF genes were much higher during ovule development in seedless grapes, suggesting a role in ovule abortion related to seedlessness. Taken together, these results indicate that VvERF proteins are involved in responses to Botrytis cinerea infection and in grape ovule development. This information may help guide strategies to improve grape production.

Abstract
During joint inflammation, various reactive oxygen species (ROS) are present in the surrounding tissue and joint fluid. In the laboratory, hydrogen peroxide (H2O2) is typically used to simulate inflammatory conditions, and media containing proteins and hyaluronic acid (HA) are employed to simulate joint synovial fluid. Electrochemical interactions between H2O2 and HA in the presence of a CoCrMo surface are expected, since HA molecules contain redox-active moieties. We hypothesized that any redox reactions of these moieties with ROS will mitigate the oxidizing effect of H2O2 on the CoCrMo surface, limiting the corrosion rate of the metal. Non-destructive electrochemical measurements (open circuit potential, linear polarization resistance and electrochemical impedance spectroscopy) were used to investigate the corrosion response of CoCrMo in synovial model fluid containing physiologically relevant concentrations of albumin proteins and hyaluronic acid, with and without H2O2. Two different molarities of H2O2, 3 mM and 30 mM, were tested. While both molarities are within physiological limits, 3mM is well within the range HA could mitigate, whereas 30 mM is not. Contrary to our hypothesis, HA did not alleviate corrosion in 3 mM H2O2 and even caused a corrosion increase in the case of 30 mM H2O2. The decrease in corrosion resistance of the alloy may be attributed to the complexation of degenerated HA molecular chains with chromium ions released from the metallic surface, which are necessary to build a protective oxide film. This finding has clinical implications, suggesting that HA accelerates corrosion of CoCrMo implants in the presence of strong inflammation.

Abstract
BACKGROUND AND PURPOSE Acidification of the tumor microenvironment from abnormal metabolism along with angiogenesis to meet metabolic demands are both hallmarks of malignant brain tumors; however, the interdependency of tumor acidity and vascularity has not been explored. Therefore, our aim was to investigate the association between pH-sensitive amine chemical exchange saturation transfer echoplanar imaging (CEST-EPI) and relative cerebral blood volume (CBV) measurements obtained from dynamic susceptibility contrast (DSC) perfusion MRI in patients with gliomas. MATERIALS AND METHODS In this retrospective study, 90 patients with histologically confirmed gliomas were scanned between 2015 and 2018 (median age, 50.3 years; male/female ratio = 59:31). pH-weighting was obtained using chemical exchange saturation transfer echo-planar imaging estimation of the magnetization transfer ratio asymmetry at 3 ppm, and CBV was estimated using DSC-MR imaging. The voxelwise correlation and patient-wise median value correlation between the magnetization transfer ratio asymmetry at 3 ppm and CBV within T2-hyperintense lesions and contrast-enhancing lesions were evaluated using the Pearson correlation analysis. RESULTS General colocalization of elevated perfusion and high acidity was observed in tumors, with local intratumor heterogeneity. For patient-wise analysis, median CBV and magnetization transfer ratio asymmetry at 3 ppm within T2-hyperintense lesions were significantly correlated (R = 0.3180, P = .002), but not in areas of contrast enhancement (P = .52). The positive correlation in T2-hyperintense lesions remained within high-grade gliomas (R = 0.4128, P = .001) and in isocitrate dehydrogenase wild-type gliomas (R = 0.4300, P = .002), but not in World Health Organization II or in isocitrate dehydrogenase mutant tumors. Both magnetization transfer ratio asymmetry at 3 ppm and the voxelwise correlation between magnetization transfer ratio asymmetry and CBV were higher in high-grade gliomas compared with low-grade gliomas in T2-hyperintense tumors (magnetization transfer ratio asymmetry, P = .02; Pearson correlation, P = .01). The same trend held when comparing isocitrate dehydrogenase wild-type gliomas and isocitrate dehydrogenase mutant gliomas (magnetization transfer ratio asymmetry, P = .04; Pearson correlation, P = .01). CONCLUSIONS A positive linear correlation between CBV and acidity in areas of T2-hyperintense, nonenhancing tumor, but not enhancing tumor, was observed across patients. Local heterogeneity was observed within individual tumors.

Abstract
To explore how Tim-3 is expressed and how its expression influences invasion and metastasis of colorectal cancer (CRC) cells. A total of 188 CRC patients were prospectively collected for this study. Meanwhile, 135 normal controls were incorporated during the same period. Intestinal samples of the CRC radical cancerous tissues, paracancerous tissues ( 5.0 cm beyond the cancer tissue) were collected for the following experiment. Furthermore, peripheral venous blood samples (10 ml) were collected from each subject. Immunohistochemical analysis, quantitative real-time polymerase chain reaction (RT-qPCR) and western blot were performed for the detection of Tim-3 in different tissues. The immunohistochemical staining results showed that a positive Tim-3 signal was localized in the cytoplasm and nucleus, observed as yellow or brown granules. Tim-3 was largely expressed in colon carcinoma tissues and normal colon mucosa tissues but was rarely expressed in the cell membrane. RT-qPCR results indicated that Tim-3 mRNA levels were significantly lower in CRC tissues than in paracancerous tissues and normal colon mucosa tissues. A trend of decreased Tim-3 mRNA levels was also found in the paracancerous tissues compared with the normal colon mucosa tissues (all P < 0.05). Western blot results revealed reduced Tim-3 protein expression in CRC tissues compared with normal colon mucosa tissues and paracancerous tissues, and Tim-3 protein expression was much lower in the paracancerous tissues than in the normal colon mucosa tissues (all P < 0.05). Furthermore, obviously lower Tim-3 mRNA levels were found in the poorly differentiated CRC patients and in those with lymph node metastasis and distant metastasis (all P < 0.05). Collectively, Tim-3 expression was mainly located in the cytoplasm and nucleus, showing down-regulated expression in colon carcinoma tissues compared with normal and paracancerous tissues. Reduced Tim-3 expression may promote CRC invasion and metastasis providing a medical reference for the treatment of CRC.

Abstract
Objective: To explore the indications and safety of orthopedic liver transplantation for polycystic liver disease (PLD). Methods: Data of 11 patients with PLD who underwent orthotopic liver transplantation between 2004 and 2013 was retrospectively analyzed. Demographic, clinical and follow-up data were collected for statistical analysis. The survival rate was calculated by Kaplan-Meier method. Results: Over a period of 10 years, the patients received modified piggyback orthopedic liver transplantation (n=9) or combined liver-kidney transplantation (n=2) for PLD. The recipients' median age was 56 years. Seven patients were classified as Gigot type Ⅱ PLD, and four were classified as Gigot type Ⅲ PLD. Eight patients had severe decreased mobility (Eastern Cooperative Oncology Group, ECOG≥3). Only three cases were Child-Pguh Class C patients and the model for end-stage liver disease (MELD) score was>20. The mean hospitalization duration was (45.4±15.3) days, and the mean length of stay in intensive care unit was (4.1±1.9) days. The perioperative mortality was 18.2% and morbidity of complications was 63.6%. The median follow-up period was 111 months. Two patients died of severe complications after combined liver-kidney transplantation. One patient died of ischemia cholangitis during follow-up. The actuarial 1-, 5-and 10-year survival rate during the follow-up period was 82.2%, 81.8%, and 65.5%, respectively. Conclusions: Liver transplantation is the only curative and safe procedure for PLD, and it provides a good long-term prognosis and high quality of life for PLD patients. Liver transplantation could be a primary option in treating progressive or advanced PLD.

Abstract
![]()
Despite
performance improvements of organic photovoltaics, the
mechanism of photoinduced electron–hole separation at organic
donor–acceptor interfaces remains poorly understood. Inconclusive
experimental and theoretical results have produced contradictory models
for electron–hole separation in which the role of interfacial
charge-transfer (CT) states is unclear, with one model identifying
them as limiting separation and another as readily dissociating. Here,
polymer–fullerene blends with contrasting photocurrent properties
and enthalpic offsets driving separation were studied. By modifying
composition, film structures were varied from consisting of molecularly
mixed polymer–fullerene domains to consisting of both molecularly
mixed and fullerene domains. Transient absorption spectroscopy revealed
that CT state dissociation generating separated electron–hole
pairs is only efficient in the high energy offset blend with fullerene
domains. In all other blends (with low offset or predominantly molecularly
mixed domains), nanosecond geminate electron–hole recombination
is observed revealing the importance of spatially localized electron–hole
pairs (bound CT states) in the electron–hole dynamics. A two-dimensional
lattice exciton model was used to simulate the excited state spectrum
of a model system as a function of microstructure and energy offset.
The results could reproduce the main features of experimental electroluminescence
spectra indicating that electron–hole pairs become less bound
and more spatially separated upon increasing energy offset and fullerene
domain density. Differences between electroluminescence and photoluminescence
spectra could be explained by CT photoluminescence being dominated
by more-bound states, reflecting geminate recombination processes,
while CT electroluminescence preferentially probes less-bound CT states
that escape geminate recombination. These results suggest that apparently
contradictory studies on electron–hole separation can be explained
by the presence of both bound and unbound CT states in the same film,
as a result of a range of interface structures.

Abstract
Objective: Accurate gating for data acquisition of computed tomography (CT) is crucial to obtaining high quality images for diagnosing cardiovascular diseases. To illustrate the feasibility of an optimized cardiac gating strategy, we present a near real-time implementation based on fusing seismocardiography (SCG) and ECG. Methods: The implementation was achieved via integrating commercial hardware and software platforms. Testing was performed on five healthy subjects (age: 24–27; m/f: 4/1) and three cardiac patients (age: 41–71; m/f: 2/1), and compared with baseline quiescence derived from echocardiography. Results: The average latency introduced by computerized processing was 5.1 ms, well within a 100 ms tolerance bounded by data accumulation time for quiescence prediction. The average prediction error associated with conventional ECG-only versus SCG-ECG-based method over all subjects were 59.58 ms and 27.24 ms, respectively. Discussion: The results demonstrate that the multimodal framework can achieve improved quiescence prediction accuracy over the ECG-only-based method in near real-time.

Abstract
Antiangiogenesis therapy plays an important role in the treatment of advanced hepatocellular carcinoma (HCC). However, treatment options for HCC recurrence after liver transplantation are currently limited. Apatinib is a small tyrosine kinase inhibitor molecule targeting vascular endothelial growth factor receptor-2. Here, we report for the first time one case of a patient with advanced HCC who received apatinib after occurring lung metastasis 7 months after liver transplantation. He took 500 mg of apatinib daily for one month, which was decreased to 250 mg daily because of side effects. The patient was confirmed to have a partial response, according to the Response Evaluation Criteria in Solid Tumors, for 10 months, and the progression-free survival time was greater than 21 months. Our data and experience have indicated that apatinib may be a good choice for HCC recurrence after liver transplantation.

Abstract
The electrical and optical properties of low-dimensional nanostructures depend critically on size and geometry and may differ distinctly from those of their bulk counterparts. In particular, ultrathin semiconducting layers as well as nanowires have already proven the feasibility to realize and study quantum size effects enabling novel ultrascaled devices. Further, plasmonic metal nanostructures attracted recently a lot of attention because of appealing near-field-mediated enhancement effects. Thus, combining metal and semiconducting constituents in quasi one-dimensional heterostructures will pave the way for ultrascaled systems and high-performance devices with exceptional electrical, optical, and plasmonic functionality. This Letter reports on the sophisticated fabrication and structural properties of axial and radial Al-Ge and Al-Si nanowire heterostructures, synthesized by a thermally induced exchange reaction of single-crystalline Ge-Si core-shell nanowires and Al pads. This enables a self-aligned metallic contact formation to Ge segments beyond lithographic limitations as well as ultrathin semiconducting layers wrapped around monocrystalline Al core nanowires. High-resolution transmission electron microscopy, energy dispersive X-ray spectroscopy, and μ-Raman measurements proved the composition and perfect crystallinity of these metal-semiconductor nanowire heterostructures. This exemplary selective replacement of Ge by Al represents a general approach for the elaboration of radial and axial metal-semiconductor heterostructures in various Ge-semiconductor heterostructures.

Abstract
Objective: To screen the key microRNAs targeting Notch signaling pathway in inner ear and investigate its potential regulating function. Methods: The interaction network and the Core-Notch network, involved with key genes in Notch signal pathway and differential-expressed microRNAs in inner ear, were constructed by bioinformatics methods. The important microRNAs in regulating Notch signaling pathway were screened via topological and GO analysis, followed by in vivo and in vitro investigation. Results: MiRNA-384-5p was identified as a key regulator specifically expressed in mouse brain and inner ear, which could down-regulate Notch1. The Notch1 expression was found significantly down-regulated in miRNA-384-5p-mimic-transfected HeLa cells. The dual-luciferase reporter gene assay further confirmed the effect of miRNA-384-5p on the down-regulation of Notch1 and Dll4 in Notch signaling pathway. Conclusions: The Core-Notch network is constructed to screen microRNAs implicated in inner ear development, and miRNA-384-5p is screened and verified to be target-regulating the Notch signaling pathway, which could be the potential target in the regeneration of impaired hair cells.

Abstract
Vacuum ultraviolet (VUV) single photon ionization mass spectrometry (SPI-MS) is a vacuum-based technique typically used for the analysis of gas phase and solid samples, but not for liquids due to the challenge in introducing volatile liquids in a vacuum. Here we present the first demonstration of in situ liquid analysis by integrating the System for Analysis at the Liquid Vacuum Interface (SALVI) microfluidic reactor into VUV SPI-MS. Four representative volatile organic compound (VOC) solutions were used to illustrate the feasibility of liquid analysis. Our results show the accurate mass identification of the VOC molecules and the reliable determination of appearance energy that is consistent with ionization energy for gaseous species in the literature as reported. This work validates that the vacuum-compatible SALVI microfluidic interface can be utilized at the synchrotron beamline and enable the in situ study of gas-phase molecules evaporating off the surface of a liquid, which holds importance in the study of condensed matter chemistry.

Abstract
To more accurately trigger data acquisition and reduce radiation exposure of coronary computed tomography angiography (CCTA), a multimodal framework utilizing both electrocardiography (ECG) and seismocardiography (SCG) for CCTA prospective gating is presented. Relying upon a three-layer artificial neural network that adaptively fuses individual ECG- and SCG-based quiescence predictions on a beat-by-beat basis, this framework yields a personalized quiescence prediction for each cardiac cycle. This framework was tested on seven healthy subjects (age: 22-48; m/f: 4/3) and eleven cardiac patients (age: 31-78; m/f: 6/5). Seventeen out of 18 benefited from the fusion-based prediction as compared to the ECG-only-based prediction, the traditional prospective gating method. Only one patient whose SCG was compromised by noise was more suitable for ECG-only-based prediction. On average, our fused ECG-SCG-based method improves cardiac quiescence prediction by 47% over ECG-only-based method; with both compared against the gold standard, B-mode echocardiography. Fusion-based prediction is also more resistant to heart rate variability than ECG-only- or SCG-only-based prediction. To assess the clinical value, the diagnostic quality of the CCTA reconstructed volumes from the quiescence derived from ECG-, SCG- and fusion-based predictions were graded by a board-certified radiologist using a Likert response format. Grading results indicated the fusion-based prediction improved diagnostic quality. ECG may be a sub-optimal modality for quiescence prediction and can be enhanced by the multimodal framework. The combination of ECG and SCG signals for quiescence prediction bears promise for a more personalized and reliable approach than ECG-only-based method to predict cardiac quiescence for prospective CCTA gating.

Abstract
Understanding magnetic phases in quantum mechanical systems is one of the essential goals in condensed matter physics, and the advent of prototype quantum simulation hardware has provided new tools for experimentally probing such systems. We report on the experimental realization of a quantum simulation of interacting Ising spins on three-dimensional cubic lattices up to dimensions 8 × 8 × 8 on a D-Wave processor (D-Wave Systems, Burnaby, Canada). The ability to control and read out the state of individual spins provides direct access to several order parameters, which we used to determine the lattice's magnetic phases as well as critical disorder and one of its universal exponents. By tuning the degree of disorder and effective transverse magnetic field, we observed phase transitions between a paramagnetic, an antiferromagnetic, and a spin-glass phase.
