Prospective Validation of an Automated Hybrid Multidimensional MRI Tool for Prostate Cancer Detection Using Targeted Biopsy: Comparison with PI-RADS-based Assessment.

Purpose To evaluate the use of an automated hybrid multidimensional MRI (HM-MRI)-based tool to prospectively identify prostate cancer targets before MRI/US fusion biopsy in comparison with Prostate Imaging and Reporting Data System (PI-RADS)-based multiparametric MRI (mpMRI) evaluation by expert radiologists. Materials and Methods In this prospective clinical trial (ClinicalTrials.gov registration no.

Spectroscopic studies and Non-Linear optical response through C/N replacement and modulation of electron Donor/Acceptor Units on naphthyridine derivatives.

This study explores the nonlinear optical (NLO) and photophysical properties of newly designed naphthyridine derivatives by density functional theory (DFT). The first hyperpolarizability (β), a key indicator of NLO activity, varies significantly depending on the substituent groups. N-substituted compounds (IUB-N series) generally show lower β values, while compounds with electron donor/acceptor groups (IUB-P series) demonstrate a broader range, with IUB-A-02 achieving the highest β value of 16,362 a.

Dengue virus infection in Saudi Arabia from 2003 to 2023: a systematic review and meta-analysis.

Dengue virus (DENV) remains one of the most common arboviral infections threatening humans. This study was conducted to systematically review the available literature and provide an updated overview of the overall prevalence of DENV infection in Saudi Arabia. The prevalence data was pooled from 21,891 participants recruited in 17 studies.

Quantitative Multi-Parametric MRI of the Prostate Reveals Racial Differences.

This study investigates whether quantitative MRI and histology of the prostate reveal differences between races, specifically African Americans (AAs) and Caucasian Americans (CAs), that can affect diagnosis. Patients (98 CAs, 47 AAs) with known or suspected prostate cancer (PCa) underwent 3T MRI (T2W, DWI, and DCE-MRI) prior to biopsy or prostatectomy. Quantitative mpMRI metrics: ADC, T2, and DCE empirical mathematical model parameters were calculated.
