Therefore, it is still of great significance to find effective biomarkers and explore the pathogenesis of HUA. Metabolomics reflects the influence of internal and external factors on system metabolism, explains the changes in metabolite levels during the development of diseases, and reveals the molecular mechanism of pathogenesis. Metabolomics is divided into untargeted metabolomics and targeted metabolomics according to different research modes. Each other's advantages can be fully utilized by combining the two so that the results of metabolomics research can be consummated. 20 HUA patients and 20 healthy individuals participated in the experiment, and untargeted metabolomics was employed to find 50 differential metabolites in HUA serum samples. Twelve candidate biomarkers were screened based on literature research and ROC Curve analysis for subsequent verif...

Considering the critical role of lncRNAs in cancer biology, further functional analysis of MCM3AP-AS1 in PTC may provide novel insights into PTC management. Subjects and methods: Paired tumor and non-tumor tissues were collected from 63 papillary thyroid carcinoma (PTC) patients. Expression levels of MCM3AP-AS1, miR-218 and GLUT1 in tissue samples were analyzed by qRT-PCR. Cell transfection was performed to explore the interactions among MCM3AP-AS1, miR-218 and GLUT1. Cell proliferation assay was performed to evaluate the effects of MCM3AP-AS1 and miR-218 on cell proliferation. Results: MCM3AP-AS1 accumulated to high levels in PTC tissues and was affected by clinical stage. MCM3AP-AS1 showed a positive correlation with GLUT1 across PTC tissues. RNA interaction prediction showed that MCM3AP-AS1 could bind to miR-218, which can directly target GLUT1. MCM3AP-AS1 and miR-218 showed no regulatory role regulating the expression of each other, but overexpression of MCM3AP-AS1 upregulated GLUT1 and enhanced cell proliferation. In contrast, overexpression of miR-218 downregulated GLUT1 and attenuated cell proliferation. In addition, miR-218 suppressed the role of MCM3AP-AS1 in regulating the expression of GLUT1 and cell proliferation. Conclusions: MCM3AP-AS1 may serve as a competing endogenous RNA of miR-218 to upregulate GLUT1 in PTC, thereby promoting cell proliferation. The MCM3AP-AS1/miR-218/GLUT1 pathway characterized in the present study might serve as a potential target to treat PTC.

In this work, colloidal CdSe/CdS 2D nanoplatelets are embedded into a microcavity, and exciton-polariton BEC is realized with an ultralow threshold of 0.5 μJ cm-2 at room temperature. The superlinear power-dependent emission, macroscopic occupation of the ground state, strong blueshift and broadening of the emission peak, and long-range coherence strongly confirm the realization of the polariton laser. This work suggests considerable prospects for colloidal nanoplatelets in low-cost, high-performance polariton devices, and coherent light sources.

Here, we report a strategy for rational design of stimulus-responsive phenothiazine derivatives with triplet-related dual emissions and high-contrast mechanochromism guided by Polymorph Prediction. The designed phenothiazine derivatives have the characters of simple structures, facile synthetic procedure and good crystalline nature. We found that the crystals of those derivatives with potential to form both quasi-axial (ax) and quasi-equatorial (eq) conformations could undergo conformation transition and show significant emission difference (Δλem> 100 nm) under mechanical force. Meanwhile, all these phenothiazine derivatives exhibit aggregation-induced emission character and emit room temperature phosphorescence or thermally activated delayed fluorescence. The significant luminescent change of these materials under different stimuli endows them promising applications in encryption and anti-counterfeiting fields.

However, it remains unclear whether this competition can be alleviated when the species richness of understory vegetation increases. In this study, we tested different gradients of understory vegetation species richness, including understory vegetation removal (UR), the retention of a single main understory vegetation species (RS), and the retention of natural diverse understory vegetation (RD) as part of a poplar (Populus deltoides ‘Nanlin-3804′) plantation, to study their effects on poplar growth, and to evaluate nitrogen (N) usage and how this was affected by the interactions between the poplar and understory vegetation. The results showed a generally lower periodic growth, and a significant decline in the foliar chlorophyll content and glutamine synthetase ac...

The deubiquitinase BRCA1–BRCA2-containing complex subunit 3 (BRCC3)-mediated nucleotide-binding domain and leucine-rich repeat receptor containing a pyrin domain 3 (NLRP3) inflammasome activation participate in this progress. This study aims to clarify whether the E3 ubiquitin ligase synoviolin (SYVN1) relieves DR via regulating the BRCC3/NLRP3 axis. The DR model was established using streptozotocin-induced mice. Immunofluorescence staining with anti-CD31, anti-glutamine synthetase, and anti-vimentin was performed to identify DR and Müller cells. Levels of pro-inflammatory cytokines, including interleukin-1β, tumor necrosis factor-α, IL-6, and IL-18, in murine serum and Müller cell supernatants were determined. Co-immunoprecipitation (Co-IP) and ubiquitination assays were used to clarify the interactions among SYVN1, BRCC3, and NLRP3. SYVN1 was reduce...

To achieve both sludge reduction and organic resource recovery, this study developed a new biorefinery technology that includes the hydrothermal treatment of sludge followed by fungal fermentation to form hyphae fibers and acidogenic fermentation to produce volatile fatty acids (VFAs). Hydrothermal treatment at 160 °C or 180 °C allows solubilization of approximately 40% of solid organics in sludge into the supernatant, resulting in significant sludge reduction and dewaterability improvement. The fermentation of the fungus Aspergillus niger converted waste organics in the hydrolyzed sludge liquor, with a chemical oxygen demand (COD) concentration of around 15,000 mg/L, into hyphae fibers, resulting in fungal biomass production of more than 1.7 g/L. After the recovery of hyphae fibers, the residual sludge liquor was further fermented to produce VFAs to a concentration of about 2500 mg COD/L. The genera Petrimonas, Arcobacter, and Aminobacterium played important roles in acidogenic fermentation. The stepped biorefinery strategy can transform approximately 35% of waste organics in the hydrothermal sludge liquor into valuable fibrous materials and VFAs for effective resource recovery.

In tumors, glycolytic metabolism has been identified to promote cell proliferation and chemoresistance. However, the molecular mechanisms underlying glycolytic metabolism and chemoresistance in colon cancer remains enigmatic. Hence, this research was designed to explore the mechanism underlying the OLR1/c-MYC/SULT2B1 axis in the regulation of glycolytic metabolism, to affect colon cancer cell proliferation and chemoresistance. Colon cancer tissues and LoVo cells were attained, where OLR1, c-MYC, and SULT2B1 expression was detected by immunohistochemistry, RT-qPCR, and western blot analysis. Next, ectopic expression and knockdown assays were implemented in LoVo cells. Cell proliferation was detected by MTS assay and clone formation. Extracellular acidification, glucose uptake, lactate production, ATP/ADP ratio, and GLUT1 and LDHA expression were measured to evaluate glycolytic metabolism. Then, the transfected ce...

METHODS For this retrospective study, 20 eyes from 20 patients undergoing myopic LASIK were included from August 2008 to November 2011. Posterior corneal curvature in peripheral 7 to 10 mm fitting zone of postoperative cornea was measured with Orbscan II topography. The ratio between anterior cornea and posterior cornea was used to calculate the preoperative total corneal power of each eye. The predicted postoperative spherical equivalent was calculated by the calculated preoperative total corneal power, power of implanted IOL, refractive error before cataract surgery and eye length from IOL-Master into the double-K method for SRK-T formula. The predicted postoperative spherical equivalent was also calculated by double-K method for SRK-T formula with clinical histo...

We investigated visual function and morphological changes in the macular area in short‐term follow‐up of patients with type 2 diabetes mellitus after intensive insulin therapy. Methods This was a prospective clinical study of nonproliferative DR patients (102 eyes, 120 patients) undergoing intensive insulin therapy. The Contrast Glare Tester (Takagi CGT‐1000) was used to examine contrast sensitivity (CS) and Heidelberg Retina Tomograph (HRT) II and Stratus Model 3000 OCT were used to observe the changes of morphology in the macular area. Follow‐up times were pre‐intensive therapy, 3 and 6 months post‐intensive therapy. Results CS at low and middle frequencies was higher at 3 and 6 months post‐therapy compared with pre‐therapy (P <0.05). Significant differences in CS at low frequency were fou...
