Exposure time was 24 h short-term exposure. Following exposure, to detect cell DNA damage, cell apoptosis, and reactive oxygen species (ROS) generation, the Comet assay test, flow cytometry, DAPI (4',6-diamidino-2-phenylindole dihydrochloride) staining, and a fluorescent probe were used, respectively. Our experiments revealed that mobile phone RFR did not cause DNA damage in marginal cells, and the rate of cell apoptosis did not increase (P > 0.05). However, the production of ROS in the 4 W/kg exposure group was greater than that in the control group (P  less then  0.05). In conclusion, these results suggest that mobile phone energy was insufficient to cause cell DNA damage and cell apoptosis following short-term exposure, but the cumulative effect of mobile phone radiation still requires further confirmation. Activation of the ROS system plays a significant role in the biological effects of RFR. Bioelectromagnetics. © 2020 The Authors.

In the present study, we aimed to determine whether there is any relationship between aortic stiffness and the severity of ED. Patients with ED were divided into 3 groups according to the International Index of Erectile Function (IIEF) scores. Mild ED was named as group 1, moderate ED as group 2 and severe ED as group 3. The values of fasting blood glucose (FBG), serum lipid values, total testosterone (T. tes), and free testosterone (F tes) were recorded. Aortic stiffness was determined by pulse wave velocity (PWV) and augmentation index (AIX) measurements. The mean or median values of the laboratory parameters among the groups were similar (p > .05). No statistical difference was found between the groups in terms of AIX value (p = .386). Mean PWV values were calculated as 7.26, 8.30 and 8.78 in group 1, group 2 and group 3 respectively. PWV values were significantly different between groups (p less then .0001). PWV values were found to be increased with increasing severity of erectile dysfunction. © 2020 Blackwell Verlag GmbH.AIMS Methylation profiling (MP) is increasingly incorporated in the diagnostic process of central nervous system (CNS) tumours at our centres in The Netherlands and Scandinavia. We aimed to identify the benefits and challenges of MP as a support tool for CNS tumour diagnostics. METHODS 502 CNS tumour samples were analysed using (850k) MP. Profiles were matched with the DKFZ/Heidelberg CNS Tumour Classifier. For each case, the final pathological diagnosis was compared to the diagnosis before MP. RESULTS In 54.4% (273/502) of all analysed cases, the suggested methylation class (calibrated score ≥0.9) corresponded with the initial pathological diagnosis. The diagnosis of 24.5% of these cases (67/273) was more refined after incorporation of the MP result. In 9.8% of cases (49/502), the MP result led to a new diagnosis, resulting in an altered WHO grade in 71.4% of these cases (35/49). In 1% of cases (5/502), the suggested class based on MP was initially disregarded/interpreted as misleading, but in retrospect the MP result predicted the right diagnosis for 3 of these cases. In 6 cases, the suggested class was interpreted as 'discrepant but non-contributory'. The remaining 33.7% of cases (169/502) had a calibrated score less then 0.9, including 7.8% (39/502) for which no class indication was given at all (calibrated score less then 0.3). CONCLUSIONS MP is a powerful tool to confirm and fine-tune the pathological diagnosis of CNS tumours, and to avoid misdiagnoses. However, it is crucial to interpret the results in the context of clinical, radiological, histopathological and other molecular information. This article is protected by copyright.

For individuals, these accounts can provide an important resource, offering a sense of control and an opportunity to re-frame past events. Furthermore, as involvement activities and the use of personal accounts have become more prominent, it is timely to examine the involvement process from the perspective of the 'lay participants'. Hence, the aim of this study is to explore how people become involved and how they construct the accounts of their lived experience. We analyse the stories of people with lived mental illness or caring experiences, who have become experts by experience (n = 13). We argue that becoming an expert by experience can help to re-contextualise past experiences and support the re-discovery of skills and expertise, leading experts by experience to construct both professionalised and politicised identities. The process has the potential to enforce narratives that portray illness experiences as motivators for social action and change. Additionally, we claim that the stories experts by experience share with health services and the public are not 'lay accounts' or ad hoc tales, but accounts constructed to serve specific purposes. © 2020 Foundation for the Sociology of Health & Illness.INTRODUCTION Few stroke survivors receive upper limb constraint-induced movement therapy (CIMT). The aims of this study were to evaluate whether a behaviour change program for occupational therapists increased the number of stroke survivors receiving CIMT, describe the time and process involved in delivering the first program, any adverse events, fidelity and dose of CIMT provided, and upper limb outcomes. Caffeic Acid Phenethyl Ester METHODS A feasibility pre-post implementation study design was used, with intervention and measures for therapists and stroke survivors. Intervention for occupational therapists was informed by the Behaviour Change Wheel and included CIMT training, barrier identification, mentoring and a community of practice. Therapists delivered 2-week CIMT programs with 11 supervision, first assisting stroke survivors to identify upper limb goals using the Canadian Occupational Performance Measure. The primary outcome was change in the number of stroke survivors receiving CIMT (program reach). Hours associated with program delivery, adverse events and participant repetitions were recorded (program fidelity and dose).
