P2X7L-transfected HEK 293 cells have phagocytic but not channel, pore, or membrane-blebbing function, and double-transfected P2X7L and P2X7A cells have reduced pore function. Heteromeric receptor complexes of P2X7A and P2X7L are predicted to have reduced numbers of ATP-binding sites, which potentially alters receptor function compared to homomeric P2X7A complexes. © 2020 Federation of American Societies for Experimental Biology.Where we fit in to the puzzle The world is standing at a crossroads and with large-scale challenges and difficulties facing us all, the role of chemists in upcoming developments will continue to be a crucial one. In this article, the United Nations 17 Sustainable Goals are outlined and highlighted to show where chemists will fit into the puzzle of trying to reshape and reform the environment and industrial practices so that targets can be reached. © 2020 Wiley-VCH Verlag GmbH & Co.

OBJECTIVES To further characterize the clinical and neuropathological characteristics of pugs with longstanding thoracolumbar myelopathy. ANIMALS Thirty client-owned pure-bred pugs with a history of more than a month of ataxia and paresis of the pelvic limbs, suggesting a myelopathy localized to the thoracolumbar spinal cord, were included in the study. METHODS Prospective clinicopathological study. Included pugs underwent a complete neurological examination and gross and histopathologic postmortem studies with focus on the spinal cord. Computed tomography (n = 18), magnetic resonance imaging (n = 17), and cerebrospinal fluid analysis (n = 27) were performed before or immediately after death. RESULTS Twenty male and 10 female pugs had a median age at clinical onset of 84 months (interquartile range, 66-96). Affected pugs presented with a progressive clinical course and 80% were incontinent. There was circumferential meningeal fibrosis with concomitant focal, malacic, destruction of the neuroparenchyma in the thoracolumbar spinal cord in 24/30 pugs. Vertebral lesions accompanied the focal spinal cord lesion, and there was lympho-histiocytic inflammation associated or not to the parenchymal lesion in 43% of the pugs. CONCLUSIONS AND CLINICAL IMPORTANCE Meningeal fibrosis with associated focal spinal cord destruction and neighboring vertebral column lesions were common findings in pugs with long-standing thoracolumbar myelopathy. © 2020 The Authors.

The standard Cox model assumes a constant covariate effect across the entire covariate domain. However, in many epidemiological and other applications, the covariate of main interest is subject to a threshold effect a change in the slope at a certain point within the covariate domain. Often, the covariate of interest is subject to some degree of measurement error. In this paper, we study measurement error correction in the case where the threshold is known. Several bias correction methods are examined two versions of regression calibration (RC1 and RC2, the latter of which is new), two methods based on the induced relative risk under a rare event assumption (RR1 and RR2, the latter of which is new), a maximum pseudo-partial likelihood estimator (MPPLE), and simulation-extrapolation (SIMEX). We develop the theory, present simulations comparing the methods, and illustrate their use on data concerning the relationship between chronic air pollution exposure to particulate matter PM10 and fatal myocardial infarction (Nurses Health Study (NHS)), and on data concerning the effect of a subject's long-term underlying systolic blood pressure level on the risk of cardiovascular disease death (Framingham Heart Study (FHS)). The simulations indicate that the best methods are RR2 and MPPLE. © 2020 WILEY-VCH Verlag GmbH & Co.

In Uruguay in December 2013, cannabis for recreational purposes was legalized. This study assessed the association between implementation of this law and changes in traffic fatality rates. Navoximod molecular weight DESIGN Interrupted time series analysis of traffic fatality rates of light motor vehicle drivers and motorcyclists in urban and rural settings. Changes are reported as step and trend effects against modelled trends in the absence of legalisation. SETTING Uruguay, Montevideo and four rural provinces (Colonia, Florida, Río Negro and San José) from January 1st , 2012 to December 31st , 2017. CASES AND MEASUREMENT Weekly traffic fatalities of light motor vehicle drivers and motorcyclists per type of vehicle. Data were gathered from the National Road Safety Agency of Uruguay and the Ministry of Transport and Public Works respectively. RESULTS Cannabis legalisation was associated with a 52.4% immediate increase (95% CI 11.6, 93.3, p = 0.012) in the light motor vehicle driver's fatality rate. However, no significant change in the motorcyclists' fatality rate was observed. In Montevideo the legislation was associated with an absolute increase in its light motor vehicle driver's fatality rate by 0.06 (95% CI 0.01, 0.11, P = 0.025), but no significant associations were observed in rural settings. CONCLUSIONS In Uruguay, the 2013 legislation legalizing recreational cannabis consumption may have been associated with an increase in fatal motor vehicle crashes, particularly in light motor-vehicle drivers and urban settings.

DESIGN A mega-analysis combining raw (as opposed to aggregate-level) data from eight studies conducted in five establishments. A multiple treatment reversal design was used for each data set, with wine glass size changed fortnightly while serving sizes were unaffected, in studies lasting between 14 and 26 weeks. SETTING AND PARTICIPANTS Five bars and restaurants in England participated in studies between 2015 and 2018, using wine glasses of five sizes 250, 300, 370, 450 and 510 ml, with the largest size only used in bars. MEASUREMENTS Daily volume of wine sold by the glass, bottle or carafe for non-sparkling wine were recorded at bars (594 days) and restaurants (427 days), averaging 4 months per study. FINDINGS Mega-analysis combining data from bars did not find a significant effect of glass size on volume of wine sold compared with 300-ml glasses the volume of wine sold using 370-ml glasses was 0.5% lower [95% confidence interval (CI) = -8.
