Summary: This study examined the immune microenvironment composition in different sites of resected pancreas specimens from pancreatic ductal adenocarcinoma (PDAC) patients. The results showed a decreased ratio of lymphoid and myeloid cells, as well as M1 and M2 macrophages, in the tumor tissue compared to non-tumorous tissue. Additionally, an increase in CD169+ macrophages was observed in patients undergoing neoadjuvant therapy, and the PDAC area had more immune-suppressive cells and a lower ratio of CD8 to M2 macrophages compared to adjacent non-tumorous tissue. Furthermore, there were more immune-suppressive cells in the central tumor area compared to the invasive front.

Summary: Our study investigates the impact of spatial confounding on the estimation accuracy of SDMs. We conduct simulation studies and analyze real vegetation data to explore how different types of spatial confounding affect model estimates. Our results show that model estimates for coarse scale covariates are likely to be biased if a species distribution depends on unobserved covariates with finer spatial scale. We provide recommendations for assessing and reducing the chance of biased model estimates due to spatial confounding.

Summary: The study aimed to assess the impact of respiratory motion and cardiac driven pulsation on renal DWI and investigate the use of asymmetrical velocity-compensated diffusion encoding waveforms for robust ADC mapping in the kidneys. The results showed that short trigger delays in respiratory-triggered scans could cause higher ADC values, especially in the right kidney. The asym-vc waveform was found to reduce ADC variation due to respiratory motion, although at the cost of reduced SNR compared to the pgse waveform.

Summary: VAV1-MYO1F is a newly identified fusion protein that is frequently detected in T-cell non-Hodgkin's lymphoma (T-NHL) patients. The pathophysiological functions of VAV1-MYO1F in lymphomagenesis are not well defined. In this study, transgenic mouse models were generated to conditionally express VAV1-MYO1F in T-cells. The results demonstrate that VAV1-MYO1F triggers cell autonomous activation of T-cell signaling and induces aberrant T-cell differentiation, proliferation, and neoplastic transformation.

Summary: This study evaluated the perception of different types of AI-based assistance and the interaction of radiologists with the algorithm's predictions and certainty measures. Four radiologists classified Breast Imaging-Reporting and Data System 4 (BI-RADS4) lesions and the effect of different AI-based assistance on their performance was measured. The results showed that trust in the algorithm's performance was mostly dependent on the certainty of the predictions in combination with a plausible heatmap, and the human-AI interaction varied widely and was influenced by personality traits.
