A Gold Rush: Designing Hydrogels for Selective Recovery in Wastewater Containing Mixed Metal Ions.

The use of synthetic hydrogels in wastewater treatment represents a promising and scalable approach to achieving clean water. By modulation of their chemical structure, hydrogels can effectively remove a wide range of toxic compounds, including emerging organic pollutants and heavy metals. For the latter, recovery is essential for both environmental protection and metal recycling.

Microbiota and social behavior alterations in a mouse model of down syndrome: Modulation by a synbiotic treatment.

Sex differences in the composition and functionality of gut microbiota are an emerging field of interest in neurodevelopmental disorders, as they may help in understanding the phenotypic disparities between males and females. This study aimed to characterize sex-related specific alterations in gut microbiota composition in a mouse model of Down syndrome (Ts65Dn mice, TS mice) through the sequencing of the PCR-amplified 16S ribosomal DNA fraction. Moreover, it intended to examine whether the modulation of gut microbiota by the administration of a synbiotic (SYN) treatment would be beneficial for the behavioral alterations observed in male and female TS mice.

Prospective Study of Contamination Spread Produced During Open Surgical vs Conventional Percutaneous vs Novel Percutaneous Tracheostomy During COVID-19 Era in a Pig Model.

Background: Because of concerns about provider contamination during tracheostomy procedures in a pandemic such as COVID-19, it is essential to objectively evaluate aerosol generation in all tracheostomy approaches, including newly developed tracheostomy procedures. We performed open surgical tracheostomy (OST), conventional percutaneous tracheostomy (CPT), and novel percutaneous tracheostomy (NPT), a modification of CPT designed to reduce contamination spread, in pig models and then compared the degree of contamination to providers using Glo Germ (Glo Germ, Moab, UT, USA).

Study Design: Six Yorkshire pigs were used for data collection.

Cardiovascular and Metabolic Benefits of Extra Virgin Olive Oil Phenolic Compounds: Mechanistic Insights from In Vivo Studies.

Extra virgin olive oil (EVOO) represents a significant source of monounsaturated fatty acids (MUFA) and vitamin E, but it is also considered a functional food, due to the content of peculiar bioactive molecules, such as phenolic compounds, being able to modulate various processes related to aging and the most common metabolic and degenerative diseases. A lot of experimental research has focused on some of these components, but in most cases, the studies were performed in vitro testing compounds at non-physiological concentrations and achieving results that cannot easily be translated in vivo. Recent clinical studies demonstrated that in vivo these compounds are able to regulate physiological functions and prevent several pathological events including metabolic and cardiovascular diseases (CVDs), which represent the main causes of death worldwide.

Glycated hemoglobin, type 2 diabetes, and poor diabetes control are positively associated with impulsivity changes in aged individuals with overweight or obesity and metabolic syndrome.

Impulsivity has been proposed to have an impact on glycemic dysregulation. However, it remains uncertain whether an unfavorable glycemic status could also contribute to an increase in impulsivity levels. This study aims to analyze associations of baseline and time-varying glycemic status with 3-year time-varying impulsivity in older adults at high risk of cardiovascular disease.
