Kapok fibers modified with cationic surfactants: Structural insights and efficient removal of Cr(VI) and bisphenol A.

In this study, kapok fiber (KF) a hollow and hydrophobic fiber, was modified with cetyltrimethylammonium bromide (CTAB) or cetylpyridinium chloride (CPC), rendering adsorbed amount of ∼0.75 × 10 mol/g. Small-angle X-ray scattering (SAXS) measurements of dry KF/CTAB and KF/CPC evidenced a periodic distance of ∼2.

Chitosan/vanillin/polydimethylsiloxane scaffolds with tunable stiffness for muscle cell proliferation.

The mechanical properties of scaffolds can significantly influence cell behavior. We propose a methodology for producing chitosan and vanillin-crosslinked chitosan films with tunable mechanical properties to be applied as scaffolds for C2C12 myoblasts. In this approach, aqueous polydimethylsiloxane (PDMS) elastomeric dispersions were prepared using polysorbate 20 as emulsifier.

[Italian Association of Epidemiology: How has the demographic, educational, and occupational profile of members changed in recent years].

In recent years, the number of members of the Italian Association of Epidemiology (AIE) has increased considerably, and their profile has undergone many changes. The aim of this work is to describe the characteristics of the members, with particular attention to those who have been continuously enrolled. To evaluate these characteristics, the data from membership forms submitted to the Association and information available on the new website in the personal profile area (period 2016-2024) were used.

Vaccines and vaccination in prison settings: availability and model of service delivery in 20 European countries.

Prisons, due to various risk factors, are environments that are conducive to infectious disease transmission, with significantly higher prevalence of infectious diseases within prisons compared to the general population. This underscores the importance of preventive measures, particularly vaccination. As part of the international project "Reaching the hard-to-reach: Increasing access and vaccine uptake among the prison population in Europe" (RISE-Vac), this study aimed to map the availability and delivery framework of vaccination services in prisons across Europe and beyond.

Integrated environmental and clinical surveillance for the prevention of acute respiratory infections (ARIs) in indoor environments and vulnerable communities (Stell-ARI): Protocol.

The epidemiological relevance of viral acute respiratory infections (ARIs) has been dramatically highlighted by COVID-19. However, other viruses cannot be neglected, such as influenza virus, respiratory syncytial virus, human adenovirus. These viruses thrive in closed spaces, influenced by human and environmental factors.
