Identification and Assessment of Human Error during the Process of Operating Various Types of Fire Apparatus

Background and Aim: Firefighting is a difficult and dangerous job. This job requires decision-making and speed of action in critical situations. Such conditions increase the probability of human error in the firefighting activities. Setting up fire apparatus as the first step of emergency response is associated with high criticality. The purpose of this study is identification and assessment th...

Thermal Excitation of the Mechanotransduction Apparatus of Hair Cells.

Although a hair bundle is normally deflected by mechanical stimuli, we found that irradiation of a hair cell from the bullfrog's sacculus with ultraviolet light causes rapid motion of the hair bundle toward its tall edge. This movement is associated with opening of mechanotransduction channels and disappears when tip links are disrupted. We localized the absorptive element responsible for the m...

Two-photon excitation fluorescence imaging of the living juxtaglomerular apparatus.

Recently, multiphoton excitation fluorescence microscopy has been developed that offers important advantages over confocal imaging, particularly for in vivo visualization of thick tissue samples. We used this state-of-the-art technique to capture high-quality images and study the function of otherwise inaccessible cell types and complex cell structures of the juxtaglomerular apparatus (JGA) in ...
