Purpose: To investigate the prognostic value of apparent diffusion coefficient (ADC) metrics, MRI characteristics, and clinicopathological parameters in predicting non-muscle-invasive bladder urothelial carcinoma (UCB) recurrence, and to develop a novel multiparametric risk stratification framework.

Methods: This retrospective single-center study (n = 135) with histologically confirmed non-muscle-invasive UCB diagnosed between January 2015 and March 2023. ADC values, vesical imaging reporting and data system (VI-RADS) scores, and clinicopathological variables were analyzed with recurrence-free survival (RFS) as the primary endpoint.

Accurate detection of viable bacteria is crucial for evaluating and monitoring the fermentation process. However, the complexity of fermentation samples presents challenges to developing precise and rapid detection tools. Here, we present a Cas13a-Csm6 tandem nuclease probe capable of the one-pot detection of viable microorganisms during fermentation, eliminating the need for nucleic acid preamplification.

Article Synopsis
  • The study aimed to predict the muscular invasion status of bladder urothelial carcinoma using advanced diffusion-weighted imaging techniques and compare the effectiveness of these techniques with the established VI-RADS system.
  • Patients with confirmed UCB underwent preoperative MRI, and several quantitative imaging parameters were analyzed to distinguish between non-muscle invasive and muscle-invasive cases.
  • The results showed that specific diffusion metrics (Axial diffusivity and Mean diffusivity) were strong predictors for muscle invasion, leading to a new MRI model that outperformed the VI-RADS system in diagnostic accuracy.

Disruptions in large-scale brain connectivity are hypothesized to contribute to psychiatric disorders, including schizophrenia, bipolar I disorder, and attention-deficit/hyperactivity disorder. However, high inter-individual variation among patients with psychiatric disorders hinders achievement of unified findings. To this end, we adopted a newly proposed method to resolve heterogeneity of differential structural covariance network in schizophrenia, bipolar I disorder, and attention-deficit/hyperactivity disorder.
