PARP1 expression and its correlation with survival is tumour molecular subtype dependent in glioblastoma

Overexpression of PARP1 exists in various cancers, including glioblastoma (GBM). Although PARP1 inhibition is a promising therapeutic target, no comprehensive study has addressed PARP1's expression characteristics and prognostic role regarding molecular heterogeneity in astrocytomas including GBM. Our aim was to evaluate PARP1's associations with survival, WHO grade, lineage specific markers, and

Treatment and suicide in severe depression. A case-control study on antidepressant therapy at last contact before suicide

Treatment at last contact in 89 persons with severe depression who committed suicide was compared with treatment at a corresponding date in 89 matched persons who did not commit suicide. No difference in electroconvulsive therapy use or prescription of antidepressant medication could be shown between those who committed suicide and those who did not. Neither was there a difference in response to t

A generalization of the sparse iterative covariance-based estimator

In this work, we extend the popular sparse iterative covariance-based estimator (SPICE) by generalizing the formulation to allow for different norm constraint on the signal and noise parameters in the covariance model. For any choice of norms, the resulting generalized SPICE method enjoys the same benefits as the regular SPICE method, including being hyperparameter free, although the choice of nor

Fundamental debates and policy choices for supporting innovation in Africa

Over the past three decades, a range of attempts have been made to raise the importance of science, technology and innovation on the policy agenda in Africa. This article explores four themes along which growth paths and patterns may be realized, namely regional and global integration, inclusive innovation, priorities and approaches to diversify African economies, and the role of the state. The ou

Multicenter patch testing with methylchloroisothizoline/methylisothiazolinone in 100 and 200 ppm within the international contact dermatitis research group

Background: The preservative methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) is a well-known contact sensitizer. Historically, there have been different opinions on the optimal patch test concentration of MCI/MI, and both 0.01% and 0.02% aqueous (aq.) have been proposed. In 2011, based on literature reviews, it was recommended that the concentration of 0.02% aq. should be used in the in

Large meta-analysis of genome-wide association studies identifies five loci for lean body mass

Lean body mass, consisting mostly of skeletal muscle, is important for healthy aging. We performed a genome-wide association study for whole body (20 cohorts of European ancestry with n = 38,292) and appendicular (arms and legs) lean body mass (n = 28,330) measured using dual energy X-ray absorptiometry or bioelectrical impedance analysis, adjusted for sex, age, height, and fat mass. Twenty-one si

Different DRB1*03 : 01-DQB1*02:01 haplotypes confer different risk for celiac disease

Celiac disease is associated with the HLA-DR3-DQA1*05:01-DQB1*02:01 and DR4-DQA1*03:01-DQB1*03:02 haplotypes. In addition, there are currently over 40 non-HLA loci associated with celiac disease. This study extends previous analyses on different HLA haplotypes in celiac disease using next generation targeted sequencing. Included were 143 patients with celiac disease and 135 non-celiac disease cont

Gas gain stabilisation in the ATLAS TRT detector

The ATLAS (one of two general purpose detectors at the LHC) Transition Radiation Tracker (TRT) is the outermost of the three tracking subsystems of the ATLAS Inner Detector. It is a large straw-based detector and contains about 350,000 electronics channels. The performance of the TRT as tracking and particularly particle identification detector strongly depends on stability of the operation parame

Online lurking and offline action: young people, social media, and (non-)participation

Research has described political participation as becoming ever more individualised (eg Bennett & Segerberg, 2013). This has been argued to be connected to the general individualisation of society, but also to affordances made possible by new media. One line of research explains political participation combining selective benefits (Olson, 1965), psychological factors (Klandermans & van Ste

Dementia with Lewy Body (DLB) Symptoms Hidden within the Diagnosis “Dementia Not Otherwise Specified” a Cross-Sectional Study in 40 Swedish Nursing Homes.

Background: Dementia with Lewy Body (DLB) is a neurocognitive disorder with core features, such as Parkinsonism, visual hallucinations, and fluctuating cognition/ excessive daytime sleepiness, and supportive features, such as rapid eye movement sleep behaviour disorder. DLB is often misdiagnosed and unrecognized in elderly individuals. A diagnosis of DLB is important because of the risk of hyperse

Modeling the role of highly oxidized multifunctional organic molecules for the growth of new particles over the boreal forest region

In this study, the processes behind observed new particle formation (NPF) events and subsequent organic-dominated particle growth at the Pallas Atmosphere-Ecosystem Supersite in Northern Finland are explored with the one-dimensional column trajectory model ADCHEM. The modeled sub-micron particle mass is up to ∼75 % composed of SOA formed from highly oxidized multifunctional organic molecules (HOMs

Influence of Vacuum Impregnation with Different Substances on the Metabolic Heat Production and Sugar Metabolism of Spinach Leaves

Vacuum impregnation (VI) has been widely used as pre-treatment prior to, e.g., minimal processing, freezing, or drying of fruit and vegetables. Most of the investigations have focused on the applicability of VI to modify physicochemical, sensory, and nutritive characteristics. However, little attention has been paid to the metabolic consequences of impregnating different substances into the plant

Measurement of the flexibility of wet cellulose fibres using atomic force microscopy

Flexibility and modulus of elasticity data for two types of wet cellulose fibres using a direct force–displacement method by means of AFM are reported for never dried wet fibres immersed in water. The flexibilities for the bleached softwood kraft pulp (BSW) fibres are in the range of 4–38 × 1012 N−1 m−2 while the flexibilities for the thermomechanical pulp (TMP) fibres are about one order of magni

Ponezumab in mild-to-moderate Alzheimer's disease : Randomized phase II PET-PIB study

Introduction The safety, pharmacokinetics, and effect on peripheral and central amyloid β (Aβ) of multiple doses of ponezumab, an anti-Aβ monoclonal antibody, were characterized in subjects with mild-to-moderate Alzheimer's disease treated for 1 year. Methods Subjects were aged ≥50 years with Mini–Mental State Examination scores 16 to 26. Cohort Q was randomized to ponezumab 10 mg/kg (n = 12) or p
