An accelerometry-based, low cost and non-invasive respiration monitoring in anesthetized mice.

Respiratory rate monitoring is essential especially for anesthetized animals in veterinary and biomedical research. Current methods often rely on invasive or wearable devices, which can stress animals, especially smaller ones like rodents. Here we present a non-invasive, environmentally integrated device that detects subtle breathing movements through waveform analyzed data via a triaxial accelerometer under a flexible fabric sheet in a trampoline-like box.

Possible roles of N- and C-terminal unstructured tails of CPI-17 in regulating Ca sensitization force of smooth muscle.

CPI-17 regulates the myosin phosphatase and mediates the agonist-induced contraction of smooth muscle. PKC and ROCK phosphorylate CPI-17 at Thr38 leading to a conformational change of the central inhibitory domain (PHIN domain). The N- and C-terminal tails of CPI-17 are predicted as unstructured loops and their sequences are conserved among mammals.
