Advanced Science, EarlyView.In AKI, initial kidney injury upregulates the expression of Cav‐1, which subsequently binds to and stabilizes SERCA2 via its scaffolding domain and through deubiquitination, thereby regulating Ca2+ homeostasis and ER stress. Conversely, Cav‐1 deficiency accelerates SERCA2 degradation, triggering Ca2+ overload and ER stress, and ultimately exacerbating ...

Integrated ultrasound transducers
Proceedings of IEEE Ultrasonics Symposium ULTSYM-94, 1994Piezoelectric polymer materials are of interest for high frequency transducer array applications primarily because the array geometry can be achieved using photolithography. The UMIST research team have fabricated up to 64-element polymer transducer arrays.

Journal of Diagnostic Medical Sonography, 2015
Diagnostic medical ultrasound transducers have evolved through the years and have contributed significantly to improved patient care. This article discusses the history and types of transducers and the elements that have changed over time. There has been a sharp transition from natural to human-made elements and from one to many in a single transducer.
