Overproduction of mucus is a hallmark of asthma. The aim of this study was to identify potentially effective therapies for removing excess mucus. The role of voltage-gated (Kir 6.1, KCa 1.1) and store-operated ion channels (SOC, CRAC) in respiratory cilia, relating to the tracheal ciliary beat frequency (CBF), was compared under the physiological and(More)
Paper focuses on main topics in frequency measurement with high speed video camera. The system is designed as phantom measurement. Phantom is realized with linear motor and controlled by DSP processor. The motor frequency is measured using image acquisition. This acquisition is done by high speed video camera. The sequences of captured images are processing(More)
Objects investigated by light transmission microscopy usually can’t be highlighted using reflection marks or equipped with sensors of cinematic parameters. In this case we often use advantages of image analysis and signal processing. Some methods for frequency measurement (using photodiode and photomultiplier) of biomechanical or microscopic objects can’t(More)
