Economic, Psychological, and Emotional Well-Being of Pregnant Women During the COVID-19 Pandemic.

Introduction: The intersection between perinatal mental health and the coronavirus disease 2019 (COVID-19) pandemic remains of significant public health importance. The current study examined the emotional and financial well-being and predictors of elevated depressive symptoms among pregnant women during the COVID-19 pandemic.

Methods: This online survey was conducted with 2118 women ≥18 years old who were pregnant at the time of the survey and living in the United States or Puerto Rico.

Between good and evil: Complexation of the human cathelicidin LL-37 with nucleic acids.

The innate immune system provides a crucial first line of defense against invading pathogens attacking the body. As the only member of the human cathelicidin family, the antimicrobial peptide LL-37 has been shown to have antiviral, antifungal, and antibacterial properties. In complexation with nucleic acids, LL-37 is suggested to maintain its beneficial health effects while also acting as a condensation agent for the nucleic acid.

Droplet Microfluidic Technology for the Early and Label-Free Isolation of Highly-Glycolytic, Activated T-Cells.

A label-free, fixation-free and passive sorting method is presented to isolate activated T-cells shortly after activation and prior to the display of activation surface markers. It uses a recently developed sorting platform dubbed "Sorting by Interfacial Tension" (SIFT) that sorts droplets based on pH. After polyclonal (anti-CD3/CD28 bead) activation and a brief incubation on chip, droplets containing activated T-cells display a lower pH than those containing naive cells due to increased glycolysis.

Production of nascent ribosome precursors within the nucleolar microenvironment of Saccharomyces cerevisiae.

35S rRNA transcripts include a 5'-external transcribed spacer followed by rRNAs of the small and large ribosomal subunits. Their processing yields massive precursors that include dozens of assembly factor proteins. In Saccharomyces cerevisiae, nucleolar assembly factors form 2 coaxial layers/volumes around ribosomal DNA.

A Toolbox for Mimicking Gastrointestinal Conditions in Children: Simulated Paediatric Breakfast Media (SPBM) for Addressing the Variability of Gastric Contents After Typical Paediatric Breakfasts.

Since co-administration of dosage forms with food can impact drug exposure, food effect studies became an integral part of oral drug product development. Studies are usually performed in healthy adults and the dosage form is co-administered with a high-fat high-calorie standard breakfast meal to mimic worst-case dosing conditions. A corresponding study design for children is lacking but would be essential for a proper risk-assessment in this vulnerable patient group.
