Fine-Tuning Genetic Circuits via Host Context and RBS Modulation.

The choice of organism to host a genetic circuit, the chassis, is often defaulted to model organisms due to their amenability. The chassis-design space has therefore remained underexplored as an engineering variable. In this work, we explored the design space of a genetic toggle switch through variations in nine ribosome binding site compositions and three host contexts, creating 27 circuit variants.

Pulmonary involvement in newly diagnosed and untreated rheumatoid arthritis and psoriatic arthritis: a prospective longitudinal study.

Objectives: To longitudinally assesses pulmonary involvement in newly diagnosed rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients over a 12-months follow-up. To identify biomarkers and establish a diagnostic algorithm for monitoring pulmonary changes.

Methods: Newly diagnosed RA and PsA patients were examined with clinical and laboratory assessments, pulmonary function tests (PFT), and chest radiography (CXR) at three-months intervals for one year.

GPR180 is a new member of the Golgi-dynamics domain seven-transmembrane helix protein family.

GOLD domain seven-transmembrane helix (GOST) proteins form a new protein family involved in trafficking of membrane-associated cargo. They share a characteristic extracellular/luminal Golgi-dynamics (GOLD) domain, possibly responsible for ligand recognition. Based on structural homology, GPR180 is a new member of this protein family, but little is known about the cellular role of GPR180.

Peer teachers as ultrasound instructors? - a systematic literature review of peer teaching concepts in undergraduate ultrasound education.

Background: As ultrasound is one of the most utilized imaging procedures in clinical practice in Germany, its integration into undergraduate medical education is imperative. Thereby, the limited availability of qualified instructors is a major challenge. Peer tutors, who are trained to instruct their peers collaboratively, could resolve staff constraints.
