Glioblastoma is a lethal disease featured with a high proliferation of tumor cells, excessive angiogenesis, and heavydrug resistance. The overall survival of glioblastoma patients was dismal even with intensive standard care. Recent advantages in immune checkpoint blockades are changing the treatment of cancers. However, the efficacy of immune checkpoint blockades in glioblastoma were unclear. Here, we investigated the roles of CD103<sup>+</sup> cells in regulating the effects of immune checkpoint blockades in glioblastoma mouse models...

The Pipeline Embolization Device (PED) is a flow diverting stent used in the treatment of a wide variety of intracranial aneurysms. The device differs from traditional stents used in stent-assisted coil embolization in that it has a tighter lattice structure with smaller cell sizes designed specifically to disrupt blood flow into aneurysms rather than only to retain coils within aneurysms. While the PED has been shown to be safe and effective, it has a unique risk profile that includes side branch and perforator vessel occlusion...

Multimodal cage-type mesoporous silicas (MCMSs) with Frank���Kasper type square���triangle tiling show a unique defect structure, so-called three-fold symmetric hexagons, or shields, which are caused by phason fluctuations in dodecagonal quasicrystals. We observed and characterized three types of configurations inside shields in both quasiperiodic and periodic 3<sup>2</sup>.4.3.4 tiling of MCMSs by transmission electron microscopy (TEM). The high-resolution TEM images of the shields were well explained by polyhedral models, which are the constituents of the Frank���Kasper type tetrahedrally close-packed structures of MCMSs...

Bone marrow aspirate concentrates (BMACs) and platelet-rich plasma (PRP) are good sources to control the differentiation of tendon derived stem cells (TDSCs) but there has been no study about the effect of BMAC-PRP complex on TDSCs and tendinopathy. The aim of this study was to investigate the effect of BMAC-PRP on the TDSCs and to find the therapeutic effect of BMAC-PRP on the rotator cuff tendon tear. Chondrogenic and osteogenic potential of TDSCs decreased, but adipogenic potential of TDSCs revealed no significant difference when they were co-cultured with BMAC-PRP...

The aberrant generation or activation of T follicular helper (Tfh) cells contributes to the pathogenesis of systemic lupus erythematosus (SLE), yet little is known about how these cells are regulated. In this study, we demonstrated that the frequency of Tfh cells was increased in lupus-prone B6.MRL-<em>Fas<sup>lpr</sup></em> (B6.<em>lpr</em>) mice and positively correlated to plasma cell proportions and serum total IgG as well as anti-dsDNA antibody levels. Transplantation of human umbilical cord mesenchymal stem cells (UC-MSCs) ameliorated lupus symptoms in B6...

We compared the therapeutic effects and mechanism of transplanted human dental pulp stem cells (hDPSCs) and human bonemarrow-derived mesenchymal stem cells (hMSCs) in a stroke model of rats and an <i>in vitro</i> ischemic model. Both hDPSCs- and hMSCs- intravenously injected rats 24&#8201;h after middle cerebral artery occlusion showed improved functional recovery and reduced infarct volume versus control rats, but the hDPSCs group showed greater reduction in infarct volume than hMSCs. The positive area for the endothelial cell marker was greater in the lesion boundary areas in the hDPSCs group than with hMSCs...

<p>Successful subretinal transplantation is limited by considerable early graft loss, despite pharmacological suppression of adaptive immunity. We postulated that early innate immune activity is a dominant factor in determining graft survival and chose a non-immunosuppressed mouse model of retinal pigment epithelial (RPE) cell transplantation to explore this.</p><p>Expression of almost all measured cytokines by DH01 RPE cells increased significantly following graft preparation and the neutrophil chemoattractant, KC/GRO/CINC, was most significantly increased...

Identification of oil type and its QC are important concerns in food control laboratories. Classifying edible oils thathave not been used (i.e., unheated) with the aid of vibrational spectroscopy has previously been reported. However, the classification of used (i.e., heat-treated) oils needs special attention. The effect of long heating times on the classification of four kinds of edible oils (canola, corn, frying, and sunflower) based on attenuated total reflectance (ATR)-FTIR spectra was surveyed. The sampling was done on the oils during a 36 h heating process (at 170°C)...

The antifungal drug itraconazole was recently found to exhibit potent antiangiogenic activity and has since been repurposed as an investigational anticancer agent. Itraconazole has been shown to exert its antiangiogenic activity through inhibition of the mTOR signaling pathway, but the molecular mechanism of action was unknown. We recently identified the mitochondrial protein VDAC1 as a target of itraconazole and a mediator of its activation of AMPK, an upstream regulator of mTOR. However, VDAC1 could not account for the previously reported inhibition of cholesterol trafficking by itraconazole, which was also demonstrated to lead to mTOR inhibition...

One of the major applications of critical metals (CMs) is in electrical and electronic equipment (EEE), which is increasingly embedded in other products, notably passenger vehicles. However, recycling strategies for future CM quantities in end-of-life vehicles (ELVs) are poorly understood, mainly due to a limited understating of the complexity of automotive embedded EEE. We introduce a harmonization of the network structure of automotive electronics that enables a comprehensive quantification of CMs in all embedded EEE in a vehicle...

Strawberry (Fragaria ananassa Duch.) possesses good antioxidant properties. Phenolic compounds in strawberries, such as anthocyanins and ellagic acid, mainly act as antioxidants. This study aimed to compare the phenolic content and expression patterns of genes involved in flavonoid biosynthesis between summer and winter strawberry cultivars affected by seasonal variation, degree of ripeness, and genotype. Antioxidant activity and the total content of phenols and flavonoids decreased with fruit ripening. Most notably, summer strawberry cultivars showed higher antioxidant activity than winter cultivars...

We study the competition of disorder and superconductivity for a generalized Kitaev model in incommensurate potentials. The generalized Kitaev model describes one dimensional spinless fermions with long-range p-wave superconducting pairing, which decays with distance <i>l</i> as a power law ���1/<i>l</i><sup>��</sup>. We focus on the transition from the topological superconducting phase to the topologically trivial Anderson localized phase, and effects of the exponent �� on this phase transition...

BACKGROUND: Tomatoes provide a significant dietary source of the carotenoids, lycopene and β-carotene. During ripening, carotenoid accumulation determines the fruit colors while chlorophyll degradation. These traits have been, and continue to be, a significant focus for plant breeding efforts. Previous work has found strong evidence for a relationship between CYC-B gene expression and the orange color of fleshy fruit. Other work has identified a point mutation in SGR that impedes chlorophyll degradation and causes brown flesh color to be retained in some tomato varieties...

Background/Aims: The presence of invasion is a diagnostic criterion of early gastric cancer (EGC) in Korea, whereas diagnosis in Japan is based on enlarged nuclei and prominent nucleoli. Moreover, the depth of invasion is the location of cancer cell infiltration in Korea, whereas it is the location of lymphovascular invasion (LVI) or cancer cell infiltration in Japan. We evaluated the characteristics of EGC with LVI to uncover the effects of different diagnostic criteria. Methods: Consecutive T1-stage EGC patients who underwent complete resection were included after endoscopic or surgical resection...
