Comparison of tracer kinetic models in differentiating malignant from normal prostate tissue using dynamic contrast-enhanced MRI.

Purpose: The aim of this study was to evaluate the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) derived kinetic parameters with high spatiotemporal resolution in discriminating malignant from normal prostate tissues.

Methods: Fifty patients with suspicious of malignant diseases in prostate were included in this study. Regions of interest (ROI) were manually delineated by experienced radiologists.

Single-Bundle Posterior Cruciate Ligament Reconstruction With Suture Tape Augmentation and Transtibial Tubercle Fixation.

The posterior cruciate ligament (PCL) is the strongest ligament of the knee and plays an important role in stabilizing the knee joint posteriorly. PCL tears are common injuries in sports injuries and traffic accidents; however, clinical outcomes after PCL reconstruction have not yet met clinicians' expectations, with a high postsurgery failure rate reported. Suture tape augmentation and supplementary fixation have shown ideal biomechanical properties in early studies.

The role of the components of PM in the incidence of Alzheimer's disease and related disorders.

Background: The associations of PM mass and various adverse health outcomes have been widely investigated. However, fewer studies focused on the potential health impacts of PM components, especially for dementia and Alzheimer's diseases (AD).

Methods: We constructed a nationwide population-based open cohort study among Medicare beneficiaries aged 65 or older during 2000-2018.

A Novel Circular Delta-XBB15 RBD Dimeric Protein Subunit Vaccine Mediated by Split Intein Elicits an Immune Response and Protection Against Multiple SARS-CoV-2 Variants in Mice.

SARS-CoV-2 continues to mutate, leading to breakthrough infections. The development of new vaccine strategies to combat various strains is crucial. Protein cyclization can enhance thermal stability and may improve immunogenicity.

Effectiveness of Total Hip Arthroplasty Combined With Hip Braces for Hip Charcot Arthropathy.

Objective: Charcot arthropathy is characterized by varying degrees of sensory loss and rapidly progressive joint destruction. Historically, limited studies indicated that Charcot arthropathy of the hip joint may be a contraindication for total hip arthroplasty (THA). Yet, some recent studies have shown that good clinical results and acceptable survival rate.
