    05) were demonstrated by the machine-learning model. Thirteen features were able to discriminate FU disease status after NCA selection. Best performance in DA classification was obtained using the combination of the 13 selected features (sensitivity 74%, specificity 58% and accuracy 66%) compared to the use of all features (sensitivity 40%, specificity 52%, and accuracy 51%). Per-site performance of the 13 selected features in DA classification were as follow T= sensitivity 63%, specificity 83%, accuracy 71%; N= sensitivity 87%, specificity 91% of and accuracy 90%; bone-M= sensitivity 33%, specificity 77% and accuracy 66%. Conclusions An artificial intelligence model demonstrated to be feasible and able to select a panel of 18F-Cho PET/CT features with valuable association with PCa patients’ outcome.Background Vascular calcification is an established feature of atherosclerosis process. The sodium/phosphate transporter PiT-1 acts as a biosensor in vascular calcification of VSMCs. -Pentavalent dimercaptosuccinic acid (99mTc-(V)-DMSA) was mediated by PiT-1 transporter in tumoral cells and we propose its evaluation in a vascular calcification in vitro model. The aim of this study was to determine if 99mTc-(V)-DMSA can follow the vascular calcification process in vascular smooth muscle cells (VSMCs) based on PiT-1 expression. Methods From a rat aortic VSMC cell line (A7r5), we set up a model of calcification within 7 days using a calcifying medium containing a high inorganic phosphate concentration. Phosphocalcic deposits were monitored with Alizarin red and Von Kossa staining and with phase contrast microscopy. PiT-1 expression was evaluated with an immunofluorescence assay and osteopontin expression, with whole cell ELISA assay. 99mTc-(V)-DMSA uptake was measured in control and calcifying conditions and compared with optical microscopy evaluation. Results Under hyperphosphatemia conditions, the VSMC cells progressively overexpressed osteopontin protein, PiT-1 transporter, and synthetized mineralized matrix with phosphocalcic deposition. 99mTc-(V)-DMSA uptake was to 2.8+/-2.08%DA/mg-protein in control cells and 42+/-24%DA/mg-protein in calcified cells (p less then 0,001). PiT-1 inhibition with phosphonoformic acid completely reverse the calcium deposition as well as the 99mTc-(V)- DMSA uptake. These results demonstrated that 99mTc-(V)-DMSA in vitro uptake is mediated by PiT-1 transporter and follow the VSMC calcification process. Conclusions These preliminary in vitro results showed 99mTc-(V)-DMSA uptake follow the phospho-calcic deposition mediated by PiT-1 transporter. This radiotracer may have some potential to detect changes of VSMC metabolism occurring in the atherosclerosis process.The COVID-19 virus has spread rapidly around the world and there are many patients in multiple countries. Great efforts have been made to find effective medications against the COVID-19. BI-3812 chemical structure This study aims to compare the effectiveness of LINCOCIN® and AZITRO® in the treatment of COVID-19 associated pneumonia. A total of 24 hospitalized patients aged between 30-80 years who were admitted to the Tarsus Medical Park Hospital between February to March 2020 was included in the study. The patients were divided into LINCOCIN® and AZITRO® treatment groups. Bronchoalveolar-lavage PCR results were compared after treatment. The mean age was 58.4±15.4 years in the LINCOCIN® group and 59.1±16.6 years in the AZITRO® group. In the LINCOCIN® group, the rate of males was 66.7% and it was 58.3% in the AZITRO® group. There were no statistical differences in terms of age and gender between the groups. On the 6th day after starting treatment, negative bronchoalveolar PCR result was 83.3% in the LINCOCIN® group and 33.3% in the AZITRO® group. The negative bronchoalveolar PCR proportion was significantly higher in the LINCOCIN® group than in the AZITRO® group. LINCOCIN® usage may be more appropriate in the treatment of COVID-19 associated pneumonia. Further studies with a large sample size should clarify these results.A previous assessment of the alignment of health technology assessments and price negotiations for new drugs for rare disorders in Canada completed between 2014 and 2018 demonstrated that it is working for governments but has yet to lead to improved access in a timely manner for all appropriate patients in all provinces. In this analysis, drugs for rare and ultra-rare disorders with a completed price negotiation or no negotiation between 2014 and 2018 in Canada, and their reimbursement recommendations and listings in Canadian public drug programs are compared with their regulatory approval in New Zealand and listing in the New Zealand National Formulary. The results show that pharmaceutical manufacturers generally seek regulatory approval for rare disorder drugs in Canada before New Zealand, and fewer rare disorder medicines receive regulatory approval in New Zealand. One reason for this difference might be New Zealand’s smaller population. However, another reason is likely the restrictive drug formulary in New Zealand. Drugs not given coverage in New Zealand are frequently made unavailable by the manufacturer. Planned changes to Canada’s pricing regulations and guidelines will significantly diminish the country’s attractiveness as a place in which pharmaceutical companies want to do business, which has the potential to negatively impact the health of all Canadians irrespective of whether they have private or public drug coverage.Alternate nostril breathing (ANB) is one of the best and easiest breathing exercises. ANB exercise has beneficial effects on cardiac function in healthy and diseased people. The objectives of this study were to assess the effects of ANB exercise on cardiac physiology among healthy medical students. This was a prospective interventional study that was conducted in the Department of Physiology, Chittagong Medical College (CMC), Chattogram, Bangladesh, from July 2017 to June 2018. A total of 100 research participants (RPs) aged 18-20 years, Year-I medical students of CMC, were selected. A simple random sampling method was adopted. The selection was done after the inclusion and exclusion criteria were applied. The age and body mass index (BMI) of the RPs were analogous in both the control and experimental groups. Cardiac parameters, like pulse and blood pressure (BP), were measured. The initial baseline data were recorded for both groups and after 4 weeks. The research respondents of the experimental group performed ANB exercise for 4 weeks.
