08, 1.30]) metabolites. In subgroup analysis stratified by types of OH-PAH metabolites, A significant stronger odds of diabetes was observed in the highest versus the lowest category of 2-PHEN (OR = 1.66, 95% CI [1.32, 2.00]), 2-NAP (OR = 1.66, 95% CI [1.16, 2.17]), 2-FLU (OR = 1.62, 95% CI [1.28, 1.97]), and 9-FLU (OR = 1.62, 95% CI [1.21, 2.04]) metabolites. Furthermore, there was a meaningfully greater likelihood of diabetes per 1-fold increase in 2-FLU (OR = 1.34, 95% CI [1.10, 1.57]), 2-PHEN (OR = 1.33, 95% CI [1.14, 1.51]), and 3-PHEN (OR = 1.19, 95% CI [1.04, 1.34]) metabolites. In conclusion, our study suggests the significant odds of association between urinary OH-PAH metabolites and diabetes. Understanding the impacts of climate change on runoff is of great importance for water resource assessments and adaptation strategy developments especially for the areas where scare and unevenly distributed water are available. Compared to the hydrological modelling method, the climate elasticity method is more flexible with the advantage of using few data in addressing the issue of investigating the effects of climate change on runoff. This study employed Budyko-based climate elasticity method, combined with temperature-based Blaney-Criddle equation, to obtain the elasticities of runoff to two major climate variables, and then applied this methodology to the upper reach of Heihe River basin, China. The runoff elasticity to precipitation in the study area was estimated to be 0.56-0.57, and the elasticity to temperature was -0.017 to -0.018. Precipitation increases showed a positive effect to runoff increases, and temperature increases showed a negative effect. Performances of 18 General Circulation Models (GCMs) of the Coupled Model Intercomparison Project Phase 5 (CMIP5) were assessed and the best GCMs were selected based on the entropy weighted TOPSIS approach. CSIRO-Mk3.6.0, CCSM4, and CanESM2 were ranked the first three with the best performances in simulating the observed precipitation and temperature over the study area. Climate projections from the above three GCMs showed that precipitation increased by 10% and 12% on average during the two periods of 2021-2050 and 2051-2080, producing 5.6% and 6.7% decreases in the projected long-term runoff compared to those in baseline period (1961-1990). Temperatures were projected to be increased by 2.0 °C and 2.9 °C for the two periods, resulting in the future long-term runoff decreased by nearly 2.0% and 2.9%, respectively. Colon cancer (CC), one of the major causes of tumor-associated death, is often presented with a heterogenic pool of cells with unique differentiation patterns. This study explored the functions that LINC00460 displayed in CC by regulating microRNA-433-3p (miR-433-3p) and Annexin A2 (ANXA2). LINC00460 expression was either silenced or overexpressed in HCT-116 and LOVO cells to explore the functional roles of LINC00460 in CC. The relationship between miR-433-3p and LINC00460/ANXA2 was analyzed using dual-luciferase reporter assay, RNA-pull down, and RNA immunoprecipitation (RIP) assays. Cell proliferation, metastasis, invasion, and apoptosis were examined in vitro, and tumorigenicity was evaluated in vivo following LINC00460 silencing. Additionally, the regulatory mechanisms were investigated using LINC00460 and ANXA2 gain- or loss-of-function experiments. We found that LINC00460 was expressed highly in CC. Downregulation of LINC00460 inhibited cell invasion and proliferation in vitro and restrained tumor growth in vivo. Moreover, LINC00460 was able to specifically bind to miR-433-3p to increase the expression of ANXA2. Furthermore, LINC00460 downregulated the E-cadherin expression and upregulated the vimentin and N-cadherin expression by upregulating ANXA2, therefore inducing epithelial-mesenchymal transition. These findings suggested that LINC00460 might function as an oncogenic long non-coding RNA (lncRNA) in CC development and could be explored as a potential biomarker and therapeutic target for CC. Long non-coding RNAs (lncRNAs) play a significant role in post-translational modifications of proteins, yet the importance of lncRNAs for SUMOylation is unknown. rhabdomyosarcoma 2 associated transcript (RMST) expression in glioma tissues and normal brain tissues was measured by quantitative real-time PCR and in situ hybridization. The functional roles of RMST in astrocytomas were demonstrated by a series of in vitro experiments. The potential mechanisms of RMST for SUMOylation were investigated by RNA immunoprecipitation, RNA pull-down, western blotting, and coimmunoprecipitation assays. We first demonstrated the oncogenic activity of lncRNA RMST by inhibiting glioma cells mitophagy. We also first determined that RMST is an enhancer of FUS SUMOylation, especially boosting SUMO1 modification at K333. SUMOylation induced by RMST contributes to the interaction between FUS and heterogeneous nuclear ribonucleoprotein D (hnRNPD) and stabilized their expression and cells mitophagy. Importantly, lncRNA RMST could serve as a promising prognostic factor for glioma patients. Our results demonstrated a previously unknown function of lncRNAs worked as an enhancer in FUS SUMOylation, and RMST will be a significant guide for the development of medications targeting gliomas. Stem cell-based therapy is one of the most attractive approaches to ischemic heart diseases, such as myocardial infarction (MI). We evaluated the cardio-protective effects of the human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) stably expressing lymphoid enhancer-binding factor 1 (LEF1; LEF1/hUCB-MSCs) in a rat model of MI. LEF1 overexpression in hUCB-MSCs promoted cell-proliferation and anti-apoptotic effects in hypoxic conditions. For the application of its therapeutic effects in vivo, the LEF1 gene was introduced into an adeno-associated virus integration site 1 (AAVS1) locus, known as a safe harbor site on chromosome 19 by CRISPR/Cas9-mediated gene integration in hUCB-MSCs. Transplantation of LEF1/hUCB-MSCs onto the infarction region in the rat model significantly improved overall survival. The cardio-protective effect of LEF1/hUCB-MSCs was proven by echocardiogram parameters, including greatly improved left-ventricle ejection fraction (EF) and fractional shortening (FS). Moreover, histology and immunohistochemistry successfully presented reduced MI region and fibrosis by LEF1/hUCB-MSCs. We found that these overall positive effects of LEF1/hUCB-MSCs are attributed by increased proliferation and survival of stem cells in oxidative stress conditions and by the secretion of various growth factors by LEF1. In conclusion, this study suggests that the stem cell-based therapy, conjugated with genome editing of transcription factor LEF1, which promotes cell survival, could be an effective therapeutic strategy for cardiovascular disease. The RNA-guided, modified type II prokaryotic CRISPR with CRISPR-associated proteins (CRISPR/Cas9) system represents a simple gene-editing platform with applications in biotechnology and also potentially as a therapeutic modality. The system requires a small guide RNA (sgRNA) and a catalytic Cas9 protein to induce non-homologous end joining (NHEJ) at break sites, resulting in the formation of inactivating mutations, or through homology-directed repair (HDR) can engineer in specific sequence changes. Although CRISPR/Cas9 is a powerful technology, the effects can be limited as a result of nuclease-mediated degradation of the RNA components. Significant research has focused on the solid-phase synthesis of CRISPR RNA components with chemically modified bases, but this approach is technically challenging and expensive. Development of a simple, generic approach to generate chemically modified CRISPR RNAs may broaden applications that require nuclease-resistant CRISPR components. We report here the development of a novel, functional U-replaced trans-activating RNA (tracrRNA) that can be in vitro transcribed with chemically stabilizing 2'-fluoro (2'F)-pyrimidines. These data represent a unique and facile approach to generating chemically stabilized CRISPR RNA. The severe and pervasive effects of multispecies foodborne microbial biofilms highlight the importance of rapid detection and diagnosis of contamination risk in the field using epifluorescence-based techniques (EBT) combined with automatic image-counting software. This study screened the hygiene quality of the environment, the carcass and the slaughtering equipment in the El-Kharga abattoir, New Valley Province, Egypt, to assess possible contamination during slaughter process. In addition, biofilm was assessed, and bacteria was enumerated by epifluorescence microscopy. Using both conventional and EBT, the highest bacterial counts were observed for the slaughtering equipment (6.6 and 5.2 cfu/cm2, respectively), followed by different parts of the carcass (4.1 and 4.4 cfu/cm2, respectively) and environmental samples (3.9 and 4.1 cfu/cm2, respectively). A high prevalence of E. coli O157H7 was observed on the slaughtering equipment (25%), which also led to carcass (1%) contamination. Moreover, Enterobacteriaceae members were detected during examination, such as Klebsiella pneumoniae, Enterobacter aerogenes, and Raoultella ornithinolytica. Despite the relatively good hygiene quality of the abattoir environment, there is also a high risk associated with biofilm formation by pathogenic microorganisms on the slaughtering equipment. Moreover, EBT showed different structures of the biofilm, including those formed at different maturation stages, such as voids, microbubbles, channels and mushroom shapes. (EBT) microscopy combined with image-counting software could be a candidate substitute to estimate efficiently, precisely and rapidly the microbial aggregation and exposure risk in field than the conventional counting techniques. Coal fly ash (CFA) is one of the most promising secondary sources of rare earth elements and yttrium (REY). This research first studied the modes of occurrence of REY in CFA collected from a China's power generation plant which utilizes a coal feedstock with an elevated REY content. The fact that rare earth minerals remain in CFA and REY associate with metal oxides was proved by emission-scanning electron microscope with an energy-dispersive X-ray spectrometer. The technical feasibility of recovery of REY from CFA was then studied through conducting various physical separation methods followed by acid leaching. It was found that REY are concentrated in fine particle size, non-magnetic and middle density fractions. Using combined physical separation processes, the REY of CFA was enriched from 782 μg·g-1to 1025 μg g-1. The acid leaching process was optimized for various parameters via the Taguchi three-level experimental design. Upon optimization, the physical separation product was leached at the optimum condition and 79.85% leaching efficiency was obtained. Based on the obtained results, a conceptual process flowsheet was developed for recovery of REY from CFA. Such recovery maximizes REY resources utilization and enhances sustainability of CFA disposal. Land surface vegetation dynamics are strongly affected by drought. Thus, understanding the responses of vegetation to drought can inform measures to increase biome stability. In this study, the normalized difference vegetation index (NDVI) and the Palmer drought severity index (PDSI) were utilized to investigate the relationship between vegetation activity and drought across different drought regions and ecological community types from 1982 to 2015. Our results showed that the highest correlation between monthly NDVI and PDSI at different timescales (1-36 months) indicated the degree of drought impact on vegetation. There were diverse responses of vegetation to drought according to the drought features and climatic environment. The northern grassland, cropland, and desert ecosystems were strongly impacted by drought. These vegetation ecosystems had a low sensitivity to drought in southern China. Drought had the strongest impact on grassland in summer, which is the high frequency drought season. The most susceptible ecosystem types to drought were those with homogenous vegetation, especially under long-term drought conditions (such as the Inner Mongolia Plateau dominated by grassland).
