Invention and improving the methods of ENT examination are closely connected with technological inventions 19th 20th centuries. The invention classical exam head mirror in 1861 improvement manufacturing compact powerful sources light (filament lamps) at time caused researchers to create new devices for examination. In particular, a head-mounted electro-mirror was created, principle which later ...

Since opportunities for spaceflight experiments are scarce, ground-based microgravity simulation devices (MSDs) offer accessible and economical alternatives gravitational biology studies. Among the MSDs, random positioning machine (RPM) provides simulated conditions on ground by randomizing rotating biological samples in two axes to distribute Earth’s gravity vector all directions over time. Re...

Fluorescent tracers and bioluminescent proteins allow researchers to label specific cells and to study their biological properties in vivo or in vitro. However, the epifluorescence compound microscopes typically used to observe labeled cells have a short working distance, and they are not suited for observing and manipulating labeled cells in vivo. Commercial epifluorescence attachments are ava...

T HE object of this study is to increase our knowledge in the field of endodontics through critical examination of tooth apices and to organize the findings in a definite statistical form. This study of 400 anterior teeth is a continuation of my previous research dealing with the root apices of 100 mandibular molars. It was extended to anterior teeth as a result of the great interest exhibited ...

OBJECTIVE To evaluate the effect of varying concentrations of brilliant blue green (BBG) and their different biochemical characteristics on retinal pigment epithelial (RPE) cells under xenon light source illumination at varying distances to identify safe parameters for intraoperative use. METHODS Human retinal RPE cells (ARPE-19) were exposed to two concentrations (0.25 and 0.50 mg/mL) of BBG...

We report on the development and applications of a new generation, commercial, optically sectioning programmable array microscope (PAM) for rapid, light efficient 3D fluorescence imaging of living specimens. The stand-alone module, including light source(s) and detector(s), features an innovative catadioptric design and a ferroelectric liquid-crystalon-silicon (LCoS) SLM instead of the DMD used...
