Integration of longitudinal deep-radiomics and clinical data improves the prediction of durable benefits to anti-PD-1/PD-L1 immunotherapy in advanced NSCLC patients.

Background: Identifying predictive non-invasive biomarkers of immunotherapy response is crucial to avoid premature treatment interruptions or ineffective prolongation. Our aim was to develop a non-invasive biomarker for predicting immunotherapy clinical durable benefit, based on the integration of radiomics and clinical data monitored through early anti-PD-1/PD-L1 monoclonal antibodies treatment in patients with advanced non-small cell lung cancer (NSCLC).

Methods: In this study, 264 patients with pathologically confirmed stage IV NSCLC treated with immunotherapy were retrospectively collected from two institutions.

CloudMC: a cloud computing application for Monte Carlo simulation.

This work presents CloudMC, a cloud computing application-developed in Windows Azure®, the platform of the Microsoft® cloud-for the parallelization of Monte Carlo simulations in a dynamic virtual cluster. CloudMC is a web application designed to be independent of the Monte Carlo code in which the simulations are based-the simulations just need to be of the form: input files → executable → output files. To study the performance of CloudMC in Windows Azure®, Monte Carlo simulations with penelope were performed on different instance (virtual machine) sizes, and for different number of instances.

[Role of cyclic AMP in gastric secretion. The secretion and mechanism of action of gastrin].

The present study involved evaluation of the role played by cyclic AMP on the secretion and mechanism of action of gastrin in man. On the basis of the results obtained, gastrin secretion induced by an excessive rise in gastric pH is accompanied by a simultaneous increase in plasma cyclic AMP concentrations (p less than 0.05) as well as a tissue cyclic AMP in the region of the fundus (p less than 0.

Deoxycytidylate deaminase in the diagnosis of acute myocardial infarction.

The diagnostic value of deoxycytidylate deaminase (dCMP) in the diagnosis of acute myocardial infarction (AMI) was examined in 31 healthy controls and 32 patients with proven AMI. Its specificity in normal controls was 93.5%.
