Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

open access: yesArtificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Opening closed inward rectifier potassium channel doors

open access: yesBritish Journal of Pharmacology, EarlyView.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

MAVS oligomerization drives a faster and more efficient antiviral signaling activation at peroxisomes compared to mitochondria

open access: yesThe FEBS Journal, EarlyView.
Cells rely on mitochondria and peroxisomes to trigger antiviral defenses via the protein MAVS. This manuscript demonstrates that the robust production of antiviral effectors resulting from MAVS activation at peroxisomes is faster than at mitochondria due to a swifter oligomerization of this protein at peroxisomal membranes. These results underscore the

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Eigenfrequency sensitivity analysis of flexible rotors

open access: yesApplied and Computational Mechanics, 2007
This paper deals with sensitivity analysis of eigenfrequencies from the viewpoint of design parameters. The sensitivity analysis is applied to a rotor which consists of a shaft and a disk. The design parameters of sensitivity analysis are the disk radius and the disk width. The shaft is modeled as a 1D continuum using shaft finite elements.
