Accordingly, YZFDF increased the expression of the phosphorylated mammalian targets of rapamycin (mTOR), leading to inhibition of autophagy (downregulated LC3 and upregulated P62). Moreover, the Aβ1-42 oligomers-induced alterations of autophagy in murine mouse brain capillary (bEnd.3) cells were blocked by RAGE small interfering RNA (siRNA). These results suggest that YZFDF restored TJ proteins' injury by suppressing autophagy via RAGE signaling. Furthermore, YZFDF reduced the pathological precipitation of Aβ in the hippocampus, and improved cognitive behavior impairment of the AD model suggested that YZFDF might be a potential therapeutic candidate for treating AD through RAGE/CaMKKβ/AMPK/mTOR-regulated autophagy pathway.Polygala tenuifolia Willd. is a traditional Chinese herbal medicine that is widely used in treating nervous system disorders. Triterpene saponins in P. tenuifolia (polygala saponins) have excellent biological activity. As a precursor for the synthesis of presenegin, oleanolic acid (OA) plays an important role in the biosynthesis of polygala saponins. However, the mechanism behind the biosynthesis of polygala saponins remains to be elucidated. In this study, we found that CYP716A249 (GenBank ASB17946) oxidized the C-28 position of β-amyrin to produce OA. Using quantitative real-time PCR, we observed that CYP716A249 had the highest expression in the roots of 2-year-old P. tenuifolia, which provided a basis for the selection of samples for gene cloning. To identify the function of CYP716A249, the strain R-BE-20 was constructed by expressing β-amyrin synthase in yeast. Then, CYP716A249 was co-expressed with β-amyrin synthase to construct the strain R-BPE-20 by using the lithium acetate method. Pralsetinib c-RET inhibitor Finally, we detected β-amyrin and OA by ultra-HPLC-Q Exactive hybrid quadrupole-Orbitrap high-resolution accurate mass spectrometry and GC-MS. The results of this study provide insights into the biosynthesis pathway of polygala saponins.Hemorrhoids are a common anorectal disease. Epidemiological studies on medication trends and risk factors using information from real-world databases are rare. Our objective was to analyze the relationship between hemorrhoid treatment prescription trends and several risk factors using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) Open Data Japan and related medical information datasets. We calculated the standardized prescription ratio (SPR) based on the 2nd NDB Open Data Japan from 2015. The correlation coefficients between the SPR of antihemorrhoidals and those of "antispasmodics," "antiarrhythmic agents," "antidiarrheals, intestinal regulators," "purgatives and clysters," "hypnotics and sedatives, antianxietics," "psychotropic agents," and "opium alkaloids preparations" were 0.7474, 0.7366, 0.7184, 0.6501, 0.6320, 0.4571, and 0.4542, respectively. The correlation coefficient between the SPR of antihemorrhoidals and those of "average annual temperature," "percentage of people who were smokers," and "percentage of people who drank regularly" were -0.7204, 0.6002, and 0.3537, respectively. The results of cluster analysis revealed that Hokkaido and Tohoku regions tended to have low average annual temperature values and high percentage of people who were smokers and had comparatively high SPRs of "antispasmodics," "antiarrhythmic agents," "antidiarrheals, intestinal regulators," "purgatives and clysters," "hypnotics and sedatives, antianxietics," "psychotropic agents," and "opium alkaloids preparations." Antihemorrhoidals are frequently used in Hokkaido and Tohoku, Japan; thus, it is important for these prefectural governments to focus on these factors when taking measures regarding health promotion.Blood transport proteins are biogenic molecules with unique and interesting inherent characteristics that make up living organisms. As the utilization of their inherent characteristics can be a groundbreaking strategy to resolve and improve several clinical problems, attempts have been made to develop pharmaceutical and biomedical preparations based on blood transport proteins for the treatment and diagnosis of disorders. Among various blood transport proteins, we focus on the immense potential of hemoglobin and albumin to serve as carriers of biomedical gases (oxygen and carbon monoxide) and anticancer agents (low-molecular compounds and antisense oligodeoxynucleotides), respectively, for the development of innovative drug delivery systems (DDS) to treat intractable disorders and solid cancers. In this review, I introduce the pharmaceutical technology, strategies, and application of DDS carriers that have been designed on the basis of the structure and function of hemoglobin and albumin. In addition, the prospect of using hemoglobin and albumin as materials for DDS carriers is discussed.Osteoarthritis (OA) is a chronic joint disease with high prevalence. However, effective treatment options for OA are still lacking. It was previously reported that LINC00473 was upregulated in patients with OA and upregulated LINC00473 might be associated with the progression of OA; however, the role of LINC00473 in OA remains to be investigated. CHON-001 human chondrocyte cells stimulated with 10 ng/mL interleukin (IL)-1β were utilized to mimic OA in vitro. Protein expression, cell apoptosis and cell proliferation of CHON-001 cells were investigated by Western blot, Annexin V and propidium iodide (PI) double staining, cell counting-8 kit assay and immunofluorescence staining respectively. The result indicated IL-1β triggered viability decrease and apoptosis in CHON-001 cells, which was alleviated by LINC00473 knockdown. Meanwhile, IL-1β-induced upregulation of cleaved caspase 3 and Bax were ameliorated by LINC00473 knockdown. Likewise, IL-1β-induced downregulation of X-linked inhibitor of apoptosis protein was alleviated by LINC00473 knockdown. In addition, LINC00473 knockdown protected CHON-001 cells against IL-1β by inhibiting the methylation of LIM mineralization protein (LMP)-1 gene. Moreover, c-Jun N-terminal kinase (JNK)/nuclear factor-kappaB (NF-κB) signaling pathway was proved to be involved in the cell protective effect of LINC00473 knockdown in IL-1β treated CHON-001 cells. Taken together, LINC00473 knockdown defended CHON-001 cells from IL-1β induced cell injury via inhibition of the methylation of LMP-1. Thus, LINC00473 might possibly act as a novel therapeutic target for OA.Pancreatic neuroendocrine neoplasms occasionally have a cystic component. We herein report a case of multiple hepatic tumors, including a huge one and a 24-mm sized pancreatic cystic lesion. The hepatic tumor showed an enhancement pattern consistent with hepatic adenoma. The pancreatic cystic lesion revealed a thickened outside border and a solid inside component, which was enhanced following a contrast study, suggesting cystic pancreatic neuroendocrine neoplasm. Surgical resection was performed. After the surgery, somatostatin receptor scintigraphy detected an occult lumbar spine metastasis. Huge multiple liver and bone metastases of the neuroendocrine neoplasm G2 component were seen, with a G1 small primary lesion.Objective Associations between aortic stiffness and cardiovascular disease events are mediated in part by pathways that include coronary microvascular dysfunction (CMD) and remodeling. However, the relationship between aortic stiffness and CMD remains unclear. The present study aimed to determine whether aortic stiffness causes CMD as evaluated by the hyperemic microvascular resistance index (hMVRI) in patients with non-obstructive coronary artery disease (CAD). Methods The intracoronary physiological variables in 209 coronary arteries were evaluated in 121 patients with non-obstructive CAD (fractional flow reserve >0.80) or reference vessels. The cardio-ankle vascular index (CAVI) as a measure of aortic stiffness and atherosclerotic risk factors were also measured. Results Univariate analyses showed that hMVRI correlated with age (β=0.24, p=0.007), eicosapentaenoic acid (EPA; β=-0.18, p=0.048), EPA/arachidonic acid (AA) (EPA/AA) ratio (β=-0.22, p=0.014) and CAVI (β=0.30, p=0.001). A multivariate regression analysis identified CAVI (β=0.25, p=0.007) and EPA/AA ratio (β=-0.26, SE=0.211, p=0.003) as independent determinants of hMVRI. Conclusion Aortic stiffness may cause CMD in patients with non-obstructive CAD via increased coronary microvascular resistance. Aortic stiffness is associated with CMD which is evaluated as hyperemic microvascular resistance in patients with non-obstructive CAD.Glioblastoma is the most common malignant tumor of the central nervous system and is treated with a combination of surgery, radiation and chemotherapy. However, the tumor often acquires radiation resistance, which is characterized by an increased DNA damage response (DDR). Here, we show that CD73, which generates extracellular adenosine from ATP, and A2B receptor, which is activated by adenosine, are involved in the γ-radiation-induced DDR and the enhanced migration ability of human glioblastoma cell line A172. link2 To investigate DDR, we evaluated ataxia telangiectasia mutated (ATM) activation and focus formation of histone H2A isoform γ (γH2AX) and p53-binding protein 1 (53BP1) in the nucleus of A172 cells after γ-irradiation. Antagonists of A2B receptor and CD73, or knockdown with small interfering RNA (siRNA), suppressed γ-radiation-induced DDR and promoted γ-radiation-induced cell death, as well as suppressing γ-radiation-induced cell migration and actin remodeling. These results suggest that activation of A2B receptor by extracellular adenosine generated via CD73 promotes γ-radiation-induced DDR, leading to recovery from DNA damage, and also enhances cell migration and actin remodeling. The CD73-A2B receptor pathway may be a promising target for overcoming radiation resistance and the acquisition of malignant phenotypes during radiotherapy of glioblastoma.This study evaluated the antifungal, physical, and mechanical properties of tissue conditioner incorporated with different amounts of zinc oxide nanoparticles (ZnOnps) at different storage times (0, 7, and 14 days). Specimens of 0, 5, 10, 15 wt% ZnOnps, or 15 wt% nystatin incorporated into tissue conditioner were fabricated (control, 5Zn, 10Zn, 15Zn, and Nys). link3 The direct contact test (n=6) was performed to evaluate the antifungal effect against C. albicans suspension. The penetration depth (n=6) and tensile bond strength (n=8) were evaluated following ISO 13139. The 15Zn significantly reduced C. albicans cell number compared with control at all storage times (p0.05). In conclusion, the 15Zn provides antifungal effect up to 14 days without adverse effects on penetration depth and tensile bond strength.The aim of this study was to compare the effects of conventional, sonic or pre-heating insertion techniques on internal void formation of bulk-fill composites with micro-computed tomography. Standardized cylindrical cavities were prepared in 160 human third molars. Four groups received different paste-like bulk-fill composites SonicFill 2 (SF2); VisCalor Bulk (VCB); Filtek One Bulk-fill restorative (FBF); Tetric EvoCeram Bulk Fill (TEB); and a conventional posterior composite, Clearfil Majesty Posterior (CMP). A hybrid CAD/CAM block was selected as a control (n=10). Composite restorations were built according to each resin composite type and insertion technique (n=10). Micro-CT was used to assess internal void rates. Data was analyzed with two-way ANOVA and Tukey's multiple comparisons test (α=0.05). CAD/CAM blocks were free of voids. For each composite, the highest void rates were observed for the sonic delivery method (p0.05). Other composites showed the lowest void rates with pre-heating technique.
