A practical distribution pattern of α-SMA-positive carcinoma associated fibroblasts indicates poor prognosis of patients with pancreatic ductal adenocarcinoma.

Purpose The present study aimed to clarify the distribution pattern of carcinoma associated fibroblasts (CAFs) across pancreatic ductal adenocarcinoma (PDAC) and its prognostic prediction value. Methods Data of two cohorts were retrospectively collected from consecutive patients who underwent primary pancreatic resection from January 2015 to December 2017. We used tumor specimens to screen out the most suitable markers for the spatial distribution analysis for CAFs subpopulations.

The Impact of Linguistic Signals on Cognitive Change in Support Seekers in Online Mental Health Communities: Text Analysis and Empirical Study.

Background: In online mental health communities, the interactions among members can significantly reduce their psychological distress and enhance their mental well-being. The overall quality of support from others varies due to differences in people's capacities to help others. This results in some support seekers' needs being met, while others remain unresolved.

Association between hormone therapy and glioma risk in US women: a cancer screening trial.

Objective: Gliomas are the most common primary brain tumors in adults, and the role of hormone therapy (HT) in their development remains controversial. This study with a cohort design aimed to investigate the association between HT use and glioma risk using the data from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial.

Methods: We analyzed data from 75,335 women, aged 50-78, who were enrolled between 1993 and 2001.

Isolation of Quick-Response High-Affinity Aptamers for Continuous and Reagentless Detection of Thrombin.

Continuous and reagentless biomolecular detection technologies are bringing an evolutionary influence on disease diagnostics and treatment. Aptamers are attractive as specific recognition probes because they are capable of regeneration without washing. Unfortunately, the affinity and dissociation kinetics of the aptamers developed to date show an inverse relationship, preventing continuous and reagentless detection of protein targets due to their low dissociation rates.

UBE2S, downregulated by miR-152-3p, facilitates prostate cancer progression through the PTEN-mediated AKT/mTOR pathway.

Objectives: In recent years, the incidence and mortality rates of prostate cancer (PCa) have still not been significantly reduced and the mechanisms of tumor onset and progression are still not fully understood. The pathogenic mechanisms and upstream regulation of UBE2S expression in prostate cancer have not been elucidated.

Methods: Here, we performed bioinformatic analysis of public databases to reveal the expression of UBE2S in PCa and its association with Gleason score, tumor staging, biochemical recurrence, and survival.
