PRIMARY scoring in 68Ga-PSMA PET/CT: correlation with prostate cancer risk groups and its potential impact on active surveillance.

Objective: The PRIMARY scoring system is a scale designed to identify clinically significant intraprostatic malignancies on 68Ga-PSMA PET/CT images. Active surveillance is a management method for patients with low-risk prostate cancer. In this study, we aimed to assess the efficacy of PRIMARY scoring in identifying appropriate candidates for active surveillance based on the distribution within prostate cancer risk groups.

Screening of phenolic components and antimicrobial properties of L. subsp. extracts by in vitro and in silico methods.

Aim: We investigated the NF-κB/MAPK inflammatory pathway and cellular apoptosis to determine the efficacy of trigonelline alkaloid (TRIG) in preventing DOX-induced lung injury.

Determining the impact of pre-pressing pretreatments applied to sugarcane on the aroma compounds and quality characteristics of sugarcane juice.

The study examined the effects of three pretreatments, blanching (5, 10, and 30 min), ultrasound (15, 20, and 30 min), and steam blanching (10, 20, and 30 min) on sugarcane, assessing their impact on sugarcane juice quality parameters and aroma compounds. The control had the highest soluble solid content, while the ultrasound-15 min (US-15 min)-treated sample had the lowest, affecting pH, total acidity, and color values significantly. Color analysis showed lower L* values and less greenish tones in treated samples.

Dielectric Detection of Single Nanoparticles Using a Microwave Resonator Integrated with a Nanopore.

The characterization of individual nanoparticles in a liquid constitutes a critical challenge for the environmental, material, and biological sciences. To detect nanoparticles, electronic approaches are especially desirable owing to their compactness and lower costs. While electronic detection in the form of resistive-pulse sensing has enabled the acquisition of geometric properties of various analytes, impedimetric measurements to obtain dielectric signatures of nanoparticles have scarcely been reported.

Methods: Forty-one ADPKD patients on tolvaptan and 40 ADPKD patients not on tolvaptan as the control group were evaluated for thirst distress sensation and intensity.

A Global Perspective on PDA Management in the Extremely Premature: Shifting Trend Toward Transcatheter Closure.

Patent ductus arteriosus (PDA) is a frequently encountered defect in infants born extremely premature (≤26 weeks' gestation). Historically, closure of the PDA was performed using cyclooxygenase inhibitor medications or by surgical ligations. However, the benefits of PDA closure using these therapies have never been demonstrated, albeit studies have previously not focused on the extremely premature infants.

Determinants of Leaky Gut and Gut Microbiota Differences in Children With Autism Spectrum Disorder and Their Siblings.

Leaky gut hypothesis is one of the well-known theory which tries to explain etiology of Autism Spectrum Disorder (ASD). Unfortunately there is still a gap of evidence to investigate the corner points of the hypothesis. The aim of this study was to investigate the determinants of leaky gut in children with ASD, their siblings and healthy controls.

In vitro effects of thirty-eight cardiac drugs on human serum paraoxonase.

In this study, the effects of 38 commonly used cardiac drugs on the human paraoxonase (PON1) were investigated. PON1 was purified from human serum blood by ammonium sulfate precipitation (60%-80%) and hydrophobic interaction chromatography (Sepharose-4B~L-tyrosine~1-napthylamine gel). All of the cardiac drugs inhibited PON1 at the micro molar level.
