Article Synopsis
- Contrast-enhanced dual-energy mammography (DEM) can detect tumors better in dense breast tissue than standard mammography, but traditional iodine-based contrast agents have significant limitations, including use restrictions and high doses.* -
- The study introduces ultrasmall molybdenum disulfide nanoparticles (MoS NPs) that are biocompatible and produce higher image contrast in DEM compared to conventional contrast agents like iopamidol.* -
- MoS NPs also show rapid elimination from the body, reducing concerns about long-term toxicity, which suggests they could effectively serve as dual-modality contrast agents for both DEM and CT imaging.*
Unlabelled: Recent advances in machine learning technologies and omics methodologies are revolutionizing dietary assessment by integrating phenotypical, clinical, and metabolic biomarkers, which are crucial for personalized precision nutrition. This investigation aims to evaluate the feasibility and efficacy of artificial intelligence tools, particularly machine learning (ML) methods, in analyzing these biomarkers to characterize food and nutrient intake and to predict dietary patterns.
Methods: We analyzed data from 138 subjects from the European Dietary Deal project through comprehensive examinations, lifestyle questionnaires, and fasting blood samples.
Chronic viral inflammation is associated with oxidative stress and changes in gut microbiota. The Mediterranean diet (MD), with recognized anti-inflammatory and antioxidant properties, modulates gut microorganisms, specifically on the interaction between extra virgin olive oil, a key component of the MD with well-documented antioxidant effects. This study investigated the influence of adherence to MD and antioxidant-rich foods (extra virgin olive oil) on biochemical, inflammatory, and microbiota profiles in patients with chronic inflammation defined as a prolonged inflammatory response due to immune dysregulation following the acute phase of the viral infection.

- Monogenic diabetes results from rare gene mutations affecting beta cell function, and this study examines how common variants may also influence young-onset type 2 diabetes (YOD) and related health issues.
- Researchers created a weighted polygenic risk score (wPRS) using data from individuals with and without YOD to explore the association of 135 common variants across 34 monogenic diabetes genes.
- The findings indicate that higher wPRS correlates with an increased likelihood of YOD and a higher risk for cardiovascular and kidney events in individuals with type 2 diabetes.
Article Synopsis
- Levonorgestrel (LNG) is primarily used as an emergency contraceptive by delaying ovulation, and this study aimed to explore its effects on the human Fallopian tube's ciliary movement and muscle contractions.
- In an experimental setup using tissue samples from women, the researchers tested LNG at various concentrations to see any changes in ciliary beat frequency and muscular contractions.
- Results showed that while LNG did not significantly affect ciliary movement or muscle tone, the highest concentration (100 ng/ml) did reduce muscular contractions, indicating that the Fallopian tube is not likely a target for LNG's contraceptive effects at typical emergency contraception doses.
