Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: To investigate the influences of bicortical anchorage on values of natural frequencies of dental implants utilizing the 3-dimensional finite element analysis.', 'Using the commercial code of Solidworks, 3-D models of a screw-shaped dental implant and a mandibular bone segment were generated. After the 3-D implant-bone complex was meshed by ABAQUS software, effects of bicortical anchorage on the buccolingual and axial first-order natural frequencies of the implant were computed.', 'Bicortical anchorage increased both the buccolingual and axial natural frequencies remarkably. As the bicortical anchorage got deeper, the frequencies correspondingly got higher.

Output: Do [ Influence of bicortical anchorage on the natural frequencies of dental implant ]?


Input: Consider Input: The author addresses whether the face bow is irrelevant for all types of prosthetic work and for planning orthognathic surgery.', 'The author searched electronic databases to find studies whose investigators used the strongest clinical evidence (that is, randomized clinical trials) and studies whose investigators incorporated the use of cinefluorography. The author found 13 studies and 1 Internet video that provided strong evidence to support the irrelevancy of the face bow transfer.', 'Evidence indicates that the face bow has nothing\xa0to do with speech, the fit and comfort of the prostheses, ridge morphology, facial contours, the color of\xa0the teeth and denture bases, the arrangement of the artificial teeth, chewing efficiency stability, and the psychological aspects of prosthodontic treatment. The cinefluorographic example showed that there was no condylar axis\xa0of rotation\xa0during functional activity, a sawing action of the\xa0mandibular incisors during the incising of\xa0toast and\xa0the\xa0mandible moving in a back and forth,\xa0rocking\xa0chair-like movement during functional activity.

Output: Is the face bow irrelevant for making prostheses and planning orthognathic surgery?


Input: Consider Input: NADH fluorescence microscopy has been used as an index of the metabolic state of tissue but is associated with various obstacles such as low spatial resolution and quenching effects of blood pigments that prevent reliable monitoring of tissue bioenergetics. The objective of this study was to develop a system to monitor tissue bioenergetics in vivo using NADH fluorescence microscopy in the rat ileal mucosa.', 'Using an inverted microscope with an epifluorescence unit and an intensified charge-coupled device camera, NADH fluorescence images were visualized. Fluorescence intensity was measured of beta-NADH solutions at varying concentration (n = 6) and pH (n = 3) and in ex vivo (n = 6) and in vivo (n = 6) preparations of ileal mucosa of Sprague-Dawley rats anesthetized with isoflurane.', 'Intravital fluorescence microscopy reveals a map of the microcirculation that permits visualization of NADH fluorescence and intercapillary areas. The system was adjusted so a linear relationship between physiological concentrations of beta-NADH and fluorescence was achieved (r(2) = 0.98, p < .0001). Decreasing the pH of the solution had no effect on fluorescence intensity and fluorescence intensity in an anoxic ex vivo ileal segment was similar to that of the in vivo ileum after ischemia. Ischemia also resulted in spatial heterogeneity that was abolished by the addition of a 550-nm LP filter.


Output: Does high-resolution intravital NADH fluorescence microscopy allow measurements of tissue bioenergetics in rat ileal mucosa?
