There was no overt effect on neuronal viability, but defects of mitochondrial function were found in the pathogenic lines. Thus, we have a human neuronal cell model of HD that may recapitulate some of the earliest stages of HD pathogenesis, namely inclusion formation and mitochondrial dysfunction. © 2020 Federation of American Societies for Experimental Biology.The incorporation of impurity ions or doping is a promising method for controlling the electronic and optical properties and the structural stability of halide perovskite nanocrystals (NCs). Herein, we establish relationships between rare earth ions doping and intrinsic emission of lead-free double perovskite Cs 2 AgInCl 6 NCs to impart and tune the optical performances in the visible light region. Tb 3+ ions were incorporated into Cs 2 AgInCl 6 NCs and occupied In 3+ sites verified by both crystallographic analyses and first-principles calculations. Trace amount of Bi doping endowed the characteristic emission ( 5 D 4 → 7 F 6-3 ) of Tb 3+ ions with new excitation peak at 368 nm rather than single characteristic excitation at 290 nm of Tb 3+ . By controlling Tb 3+ ions concentration, the emission colors of Cs 2 AgInCl 6 Bi,Tb NCs could be continuously tuned from green to orange, due to the efficient energy transfer channel from self-trapped excitons to Tb 3+ ions. Our study provides the salient features of the material design of lead-free perovskite NCs and to expand their luminescence applications. © 2020 WILEY-VCH Verlag GmbH & Co.

MATERIALS AND METHODS Patients over 70 years of age starting new chemotherapy regimens were prospectively included in a multicenter study. A prechemotherapy assessment that included sociodemographics, tumor/treatment variables, and geriatric assessment variables was performed. Association between these factors and the development of grade 3-5 toxicity was examined by using logistic regression. RESULTS A total of 551 patients were accrued. Chemotherapy doses (odds ratio [OR] 1.834; 95% confidence interval [CI] 1.237-2.719) and creatinine clearance (OR 0.989; 95% CI 0.981-0.997) were the only factors independently associated with toxicity. Only 19% of patients who received reduced doses of chemotherapy and had a creatinine clearance ≥40 mL/minute had grade 3-4 toxicity, compared with 38% of those who received standard doses or had a creatinine clearance less then 40 mL/minute (p less then .0001). However, no satisfactory multivariate model was obtained using different selection approaches. CONCLUSION Chemotherapy doses and renal function were identified as the major risk factors for developing severe toxicity in the older patient. These factors should be considered when planning to initiate a new chemotherapy regimen and should also lead to a closer follow-up in these patients. IMPLICATIONS FOR PRACTICE Older patients are more vulnerable to chemotherapy toxicity. However, standard tools are inadequate to identify who is at higher risk of developing chemotherapy-related complications. Chemotherapy doses (standard vs. reduced) and renal function were identified as the major risk factors for developing severe toxicity in the elderly. These factors should be considered when planning to initiate a new chemotherapy regimen and should also lead to a closer follow-up. © AlphaMed Press 2020.Chromosome segregation errors in mammalian embryos are common and jeopardize embryo health. Here, we perform for the first time 4-Dimensional imaging and tracking of chromosomes and centromeres through each preimplantation mitotic cell division in mouse embryos to define the normal dynamics of chromosome segregation. We show that a microtubule (MT)-dependent inward movement of chromosomes occurs at the time of nuclear envelope breakdown (NEBD), particularly in the earliest cell divisions, to position chromosomes prior to spindle assembly. Establishment of a rudimentary metaphase plate occurs immediately after NEBD, and is followed by a progressive alignment and biorientation of mitotic chromosomes. Stable end-on kinetochore-MT attachments form rapidly and attachment errors are uncommon. Altogether our data describe a rapid and efficient spindle assembly pathway that apparently minimizes the need for canonical MT attachment error correction in normally dividing embryos. © 2020 Her Majesty the Queen in Right of Canada The FASEB Journal © 2020 John Wiley & Sons Ltd.The circadian rhythm plays a central role in immune function, and its disruption has been closely linked to the etiology of depression. However, the mechanisms underlying the association between depression and circadian rhythm remain unclear. CD532 We found that mice deficient of Per2, a central clock component of circadian output, were resilient to neuroinflammation-induced depressive behavior. After repeated central lipopolysaccharide (LPS) injections, MCP-1, MIP-1β, and RANTES increased in wild type (WT) but not in Per2-deficient mice. In addition, intracerebroventricular injection of RANTES resulted in depression-like behavior, and Met-RANTES, a CCR5 antagonist, could reverse depression-like behavior induced by LPS treatments. These results indicated that the Per2 gene contributes to depression via chemokines, especially RANTES. Furthermore, BMAL1 expression decreased in LPS-treated Per2-deficient mice and BMAL1 could bind to the promoter of Rantes, indicating clock gene can act as a regulator for neuroinflammation. In conclusion, Rantes, a clock-controlled gene (CCG), is involved in clock-immunological mechanisms underlying the effects of Per2 on neuroinflammation-induced depression-like behavior. © 2020 The Authors.

To better understand the role of DNA methylation in benzene toxicity, peripheral blood mononuclear cells were collected from six benzene-poisoning patients and six matched controls for genome-wide DNA methylation screening by Illumina Infinium Methylation 450 BeadChip. The Gene Chip Human Gene 2.0 ST Array (Affymetrix) was used to analyze global mRNA expression. Compared with the corresponding sites of controls, 442 sites in patients were hypermethylated, corresponding to 253 genes, and 237 sites were hypomethylated, corresponding to 130 genes. The promoter methylation and mRNA expression of CSF3R, CREB5, and F2R were selected for verification by bisulfite sequencing and real-time PCR in a larger data set with 21 cases and 23 controls. The results indicated that promoter methylation of CSF3R (p = .005) and F2R (p = .015) was significantly higher in cases than in controls. Correlation analysis showed that the promoter methylation of CSF3R (p  less then  .
