BACKGROUND The success of endodontic treatment is greatly affected by the location of the root canals. The purpose of this study was to evaluate the root and canal morphology of permanent maxillary first and second molars in a Polish population using cone-beam computed tomography scanning. METHODS Cone-beam computed tomography (CBCT) scans of maxillary first and second molars the maxilla were...

Pesticides are used worldwide within agriculture to protect crops and ensure the quantity and quality of the harvest. However, intensive and inappropriate pesticides application can directly or indirectly affect different parts of the environment, especially water source. Besides the occurrence of pesticides in drinking water, control of pesticide presence in surface and groundwater is also ver...

Dynamics and kinematics of the angular vestibulo-ocular reflex in monkey: effects of canal plugging. J. Neurophysiol. 80: 3077-3099, 1998. Horizontal and roll components of the angular vestibulo-ocular reflex (aVOR) were elicited by sinusoidal rotation at frequencies from 0.2 Hz (60 degrees/s) to 4.0 Hz ( approximately 6 degrees/s) in cynomolgus monkeys. Animals had both lateral canals plugged ...
