We also measured Ca2+ dynamics in ORAI1/2-deficient (shOrai1/2) LS8 cells and in cells with siRNA knock-down of Trpm7. We found that primary enamel cells stimulated with the TRPM7 activator potentiated Ca2+ influx via SOCE compared to control cells. However, blockade of TRPM7 with NS8593 did not decrease the SOCE peak. Furthermore, activation of TRPM7 in shOrai1/2 LS8 cells lacking SOCE failed to elicit Ca2+ influx, and Trpm7 knock-down had no effect on SOCE. Taken together, our data suggest that TRPM7 is a positive modulator of SOCE potentiating Ca2+ influx in enamel cells, but its function is fully dependent on the prior activation of the ORAI channels. BACKGROUND Individuals with stroke often experience difficulty in dual-task walking and are prone to falling when walking and talking. Previous studies in other populations have suggested that non-invasive brain stimulation could enhance dual-task gait performance by stimulating dorsolateral prefrontal cortex (DLPFC) or supplementary motor area (SMA). It was unclear if the benefits of brain stimulation would be observed in individuals with stroke. RESEARCH QUESTION Would single-session 5 Hz rTMS applied to DLPFC or SMA improve dual-task gait performance in individuals with stroke? METHODS This single group repeated measure study included fifteen individuals with left chronic stroke (mean age = 58 years). Participants received 5 Hz rTMS to either DLPFC, SMA, or M1 of the left lesioned hemisphere across three different sessions. Single- and dual-task gait speed was assessed before and after rTMS with the dualtask gait being walking and counting backward by 3 s. RESULTS We observed that rTMS to left DLPFC resulted in a greater increase in dual-task gait speed, but not single-task gait speed, compared to the other two stimulation sites (M1 and SMA) but the difference was not statistically significant (p = 0.06). Five out of fifteen participants demonstrated a clinically significant improvement in dual-task gait speed (> 0.1 m/s) after rTMS to DLPFC. SIGNIFICANCES The results suggest that DLPFC could be a potential treatment target to improve dual-task gait performance in persons with chronic stroke. Reactive Oxygen Species (ROS) are essential cellular messengers required for cellular homeostasis and regulate the lifespan of several animal species. The main site of ROS production is the mitochondrion, and within it, respiratory complex I (CI) is the main ROS generator. ROS produced by CI trigger several physiological responses that are essential for the survival of neurons, cardiomyocytes and macrophages. Here, we show that CI produces ROS when electrons flow in either the forward (Forward Electron Transport, FET) or reverse direction (Reverse Electron Transport, RET). We demonstrate that ROS production via RET (ROS-RET) is activated under thermal stress conditions and that interruption of ROS-RET production, through ectopic expression of the alternative oxidase AOX, attenuates the activation of pro-survival pathways in response to stress. Accordingly, we find that both suppressing ROS-RET signalling or decreasing levels of mitochondrial H2O2 by overexpressing mitochondrial catalase (mtCAT), reduces survival dramatically in flies under stress. Our results uncover a specific ROS signalling pathway where hydrogen peroxide (H2O2) generated by CI via RET is required to activate adaptive mechanisms, maximising survival under stress conditions. Wet skid-resistance is of paramount importance for road safety as it has been recognized to affect wet-road accidents. Recently European Regulations are introducing mandatory classification for tyre friction performance by means of tyre labelling procedure. In this paper an experimental study has been carried out in order to search for a relationship between indexes employed in the tyre and pavement classification. Coupled friction tests have been performed in a controlled manner on five test track with varying texture properties and significant statistical relationship has been derived between Wet Grip Index (WGI), as defined in the European Tyre Labelling Procedure and the International Friction Index (IFI), according to World Road Association (PIARC) friction harmonization experiment. If a temperature correction of skid data is applied a good correlation between WGI and IFI can be obtained. Although the experimental study has to be integrated with a wider measurement campaign, preliminary results seem to indicate that a unified wet tyre-road classification can be pursued allowing a better awareness of the road safety level among road users. Acute myeloid leukemia (AML) is primarily a disease of older adults. Many older patients with AML are not candidates for intensive chemotherapy regimens aimed at inducing remission before transplantation. The prognosis for this patient population remains poor, with 5-year overall survival (OS) rates of less than 10 %. At present, there is no standard of care, and clinical trials should be considered. Hypomethylating agents often are the mainstay of treatment in this setting; however, improved genetic profiling and risk stratification based on molecular, biological, and clinical characteristics of AML enhance the ability to identify an individual patient's risk and can refine therapeutic options. Over the past 2 years, several novel agents have been approved for AML patients in either the frontline or relapsed settings. Additional agents have also shown promising activity. It is becoming a challenge for physicians to navigate these different options and select the optimal therapy or combination of therapies. The aim of this review is to summarize the available information to assist with treatment decisions for leukemia patients who are not suitable for intensive chemotherapy. BACKGROUND The objective of this study was to test the effect of chemotherapy and/or radical cystectomy (RC) and/or radiotherapy (RT) on survival of patients with non-metastatic small-cell carcinoma of the urinary bladder (SCCUB). MATERIALS AND METHODS Within the Surveillance, Epidemiology, and End Results registry (2001-2016), we identified patients with non-metastatic (T1-4, N0, M0) SCCUB. Treatment was defined as chemotherapy alone, chemotherapy + RC, and chemotherapy + RT. Temporal trends, cumulative incidence plots, and multivariable competing risks regression models were used. Fostamatinib cost RESULTS Of 595 patients with SCCUB, 230 (38.5%), 159 (27%), and 206 (34.5%) were treated with chemotherapy alone, chemotherapy + RC, and chemotherapy + RT, respectively. The rates of chemotherapy + RC increased (estimated annual percentage changes [EAPC], +5.9%; P = .002). Conversely, chemotherapy alone (EAPC, -1.7%; P = .1) and chemotherapy + RT rates decreased (EAPC -2.2%; P = .08). Overall, 5-year cancer-specific mortality (CSM) rates were 44%, 29%, and 40% for patients treated with chemotherapy alone, chemotherapy + RC, and chemotherapy + RT, respectively (P = .
