Finding the ideal solvent for the analysis of polar analytes using supercritical fluid chromatography.

The analysis of polar analytes with the help of hydrophilic interaction liquid chromatography (HILIC) using classic methods of high-performance liquid chromatography is not without its downsides. In these applications, acetonitrile is prevalent as main eluent and sample diluent. This results not only in slow diffusion processes during the separation, but also in often unstable sample solutions where polar analytes are concerned.

Readiness for influenza and COVID-19 vaccination in Germany: a comparative analysis.

Introduction: Vaccination readiness refers to psychological motives and beliefs that decisively determine individual and collective vaccination prevention behavior. Readiness to be vaccinated depends on expected individual and social benefits and harms. Differences exist in the perception of the threat of potential influenza vs.

Different risk and protective factors predict change of planning ability in middle versus older age.

Age-related cognitive decline has become an increasingly relevant public health issue. However, risk and protective factors of cognitive decline have yet to be investigated prospectively taking into account genetic, lifestyle, physical and mental health factors. Population-based data from middle-aged (40 to 59 years; N = 2,764) and older individuals (60 to 80 years; N = 1,254) were drawn from a prospective community cohort study using the Tower of London (TOL) planning task.

Analyzing early childhood allergy prevention motivation of mothers of infants and its predictors using latent class analysis and structural equation modelling.

Background: Allergic diseases are among the most common chronic diseases in childhood. Early childhood allergy prevention (ECAP) behaviors of those caring for the infant during pregnancy and the first months of life may influence the risk of allergy development over the life course. Motivation and intention to use appropriate primary ECAP measures are thus of critical importance.
