Obesity-induced insulin resistance is a risk factor for diabetes and cardiovascular disease. However, the mechanisms underlying endothelial senescence in obesity, and how it impacts obesity-induced insulin resistance remain incompletely understood. In this study, transcriptome analysis revealed that the long non-coding RNA (lncRNA) Maternally expressed gene 3 (Meg3) is one of the top differentially expressed lncRNAs in the vascular endothelium in diet-induced obese mice. Meg3 knockdown induces cellular senescence of endothelial cells characterized by increased senescence-associated β-galactosidase activity, increased levels of endogenous superoxide, impaired mitochondrial structure and function, and impaired autophagy. Moreover, Meg3 knockdown causes cellular senescence of hepatic endothelium in diet-induced obese mice. Furthermore, Meg3 expression is elevated in human nonalcoholic fatty livers and nonalcoholic steatohepatitis livers, which positively correlates with the expression of CDKN2A encoding p16, an important hallmark of cellular senescence. Meg3 knockdown potentiates obesity-induced insulin resistance and impairs glucose homeostasis. Insulin signaling is reduced by Meg3 knockdown in the liver and, to a lesser extent, in the skeletal muscle, but not in the visceral fat of obese mice. We found that the attenuation of cellular senescence of hepatic endothelium by ablating p53 expression in vascular endothelium can restore impaired glucose homeostasis and insulin signaling in obesity. In conclusion, our data demonstrate that cellular senescence of hepatic endothelium promotes obesity-induced insulin resistance, which is tightly regulated by the expression of Meg3. Our results suggest that manipulation of Meg3 expression may represent a novel approach to managing obesity-associated hepatic endothelial senescence and insulin resistance.Nitrogen (N) and phosphorus (P) are two of the most important nutrients for plant growth and crop yields. In the last decade, plenty of studies have revealed the genetic factors and their regulatory networks which are involved in N and/or P uptake and utilization in different model plant species, especially in Arabidopsis and rice. However, increasing evidences have shown that epigenetic regulation also plays a vital role in modulating plant responses to nutrient availability. In this review, we make a brief summary of epigenetic regulation including histone modifications, DNA methylation, and other chromatin structure alterations in tuning N and P responses. We also give an outlook for future research directions to comprehensively dissect the involvement of epigenetic regulation in modulating nutrient response in plants.In this study, the ability of laccase Gl-LAC-4, purified from Ganoderma lucidum, to degrade and detoxify two representative alkylphenol pollutants, 4-n-octylphenol and 2-phenylphenol, was systematically studied. Gl-LAC-4 laccase had a very strong ability to degrade high concentrations of 4-n-octylphenol, 2-phenylphenol, and alkylphenol mixtures. The degradation speed of Gl-LAC-4 toward 2-phenylphenol was very fast. Gl-LAC-4 displayed strong tolerance for a variety of metal salts and organic solvents in the degradation of alkylphenols. Gl-LAC-4 showed strong tolerance for high concentrations of various metal salts, such as MgSO4, MnSO4, Na2SO4, CuSO4, ZnSO4, CdSO4, and K2SO4, in the degradation of 4-n-octylphenol and 2-phenylphenol.In the case of the same metal cation, the inhibitory effect of the metal salt with Cl- as the anion on the degradation of 4-n-octylphenol and 2-phenylphenol by laccase was stronger than that of the metal salt with SO42- as the anion. An increase in the number of chloride ions caused a greater inhibitory effect on alkylphenol degradation by laccase. Gl-LAC-4 exhibited strong tolerance for glycerol, ethylene glycol, butanediol, propylene glycol, and organic solvent mixtures in the degradation of alkylphenols. Gl-LAC-4 treatment significantly reduced or eliminated the phytotoxicity of 4-n-octylphenol and 2-phenylphenol.
To validate a translated and culturally adapted version of the Morisky Medication Adherence Scale for use in Spanish population, and to examine the psychometric properties of this scale in patients with type 2 diabetes mellitus in Spain.

This cross-sectional study was conducted in a single university hospital in Spain. Patients diagnosed with type 2 diabetes mellitus at least 1 year before inclusion, being treated with anti-diabetic medication were included.

We used the Spanish version of the scale to measure treatment adherence.

three level categorical scale is broken down into low adherence (score of <6), medium adherence (score of 6 to <8) and high adherence (score of 8). To validate the questionnaire, we measured internal consistency through Cronbach's α, confirmed construct validity through an exploratory principal component analysis and assessed test-retest reliability.

232 patients met the inclusion criteria. Compstatin in vitro The Cronbach's α coefficient was 0.40 (95% CI 0.28-0.52). link2 The exploratory principal component analysis showed three components. The intraclass correlation coefficient was 0.718 (95% CI 0.564-0.823).

the Spanish version of the Morisky Medication Adherence scale showed low internal consistency, the exploratory factor analysis identified three dimensions, and the test-retest reliability was acceptable, therefore, psychometric properties of MMAS-8 are not suitable for measuring medication adherence in type 2 diabetes mellitus patients from Spain.

A novel fast kilovoltage switching dual-energy CT with deep learning [Deep learning based-spectral CT (DL-Spectral CT)], which generates a complete sinogram for each kilovolt using deep learning views that complement the measured views at each energy, was commercialized in 2020. The purpose of this study was to evaluate the accuracy of CT numbers in virtual monochromatic images (VMIs) and iodine quantifications at various radiation doses using DL-Spectral CT.

Two multi-energy phantoms (large and small) using several rods representing different materials (iodine, calcium, blood, and adipose) were scanned by DL-Spectral CT at varying radiation doses. Images were reconstructed using three reconstruction parameters (body, lung, bone). The absolute percentage errors (APEs) for CT numbers on VMIs at 50, 70, and 100keV and iodine quantification were compared among different radiation dose protocols.

The APEs of the CT numbers on VMIs were <15% in both the large and small phantoms, except at the minimum dose in the large phantom. There were no significant differences among radiation dose protocols in computed tomography dose index volumes of 12.3mGy or larger. The accuracy of iodine quantification provided by the body parameter was significantly better than those obtained with the lung and bone parameters. Increasing the radiation dose did not always improve the accuracy of iodine quantification, regardless of the reconstruction parameter and phantom size.

The accuracy of iodine quantification and CT numbers on VMIs in DL-Spectral CT was not affected by the radiation dose, except for an extremely low radiation dose for body size.

We assessed the role of adjuvant chemotherapy (ACT) in patients with advanced nasopharyngeal carcinoma treated with concurrent chemoradiotherapy (CCRT) and investigated the prognostic factors for recurrence and survival.

Between January 2008 and January 2018, 88 non-metastatic nasopharyngeal carcinoma patients treated with CCRT and with or without ACT in two institutions were retrospectively reviewed. link3 The initial tumor response evaluation was performed 1month after CCRT completion. Survival analysis was performed for factors such as initial tumor regression, ACT and other clinical factors. Subgroup analysis was performed for the four-group categorized according to tumor regression and ACT (CR with/without ACT, non-CR with/without ACT).

Complete response (CR) 1month after CCRT was a favorable prognosticator for progression-free survival (PFS) (hazard ratio [HR] 3.16, 95% confidence interval [CI] 1.02-9.85, p=0.046) and overall survival (OS) (HR 3.19, 95% CI 1.14-8.93, p=0.027). Also, ACT was an independent factor for PFS (HR 0.38, 95% CI 0.15-0.98, p=0.047) and OS (HR 0.37, 95% CI 0.13-0.99, p=0.047). In subgroup analysis, the CR after CCRT followed by ACT group showed significantly higher locoregional recurrence-free survival (p=0.02), OS (p=0.003), distant-metastasis free survival (p=0.07), and PFS (p=0.01) than the other three groups.

Tumor regression 1month after CCRT, and administration of ACT identified as an independent prognosticator for PFS and OS in this study. Even patients who show early tumor regression after CCRT may benefit from ACT. Further randomized trials should define the role of ACT in patients with nasopharyngeal cancer who achieved CR after CCRT.

Cognitive Orientation to daily Occupational Performance (CO-OP) is recommended for its effectiveness in improving activity performance in children with Developmental Coordination Disorder (DCD). Since parental support is a key element in CO-OP, parental coaching seems relevant to be investigated.

Compare the efficacy of the CO-OP Approach with and without additional parental coaching to improve activity and participation in children with DCD.

Randomized clinical trial with 7-12-years-old children with DCD, randomly assigned to experimental (E-group) or active control (AC-group) groups, with 11 children each. Both groups received traditional CO-OP, E-group received four additional parental group-coaching sessions. Occupational performance and satisfaction on intervention goals were measured at baseline, post-intervention, and follow-up. Participation, motor performance and executive function were assessed at baseline and post-intervention.

CO-OP with and without additional parental coaching resulted in improved occupational performance according to children, parents, and external evaluators. Children showed statistically significant gains in motor performance and cognitive flexibility. Participation measures did not change.

As coaching did not add additional gains, parent's required participation in CO-OP might be enough to support children's occupational performance.
