Studies suggest that brain-derived neurotrophic factor (BDNF) plays an essential role in regulating memory-related neuroplasticity in the hippocampus. Type 2 diabetes (T2DM) is associated with impairment in many domains of cognitive function which may result from reduced BDNF; however, the correlation of BDNF with cognitive impairment in T2DM has not been(More)
Target restoration space (TRS) is the most precise space required for designing optimal prosthesis. TRS consists of an internal or external tooth space to confirm the esthetics and function of the final restoration. Therefore, assisted with quantitive analysis transfer, TRS quantitative analysis is a significant improvement for minimum tooth preparation.(More)

In this paper, we introduce two autoradiography imaging systems from Packard Instrument Company, that provide unmatched speed, accuracy, sensitivity, and resolving power for radioisotopic imaging in biomedical research. The first system is a direct nuclear imaging system, which provides fast and accurate nuclear counting without intermediate steps. Data are(More)
Although traditional tooth preparation techniques (e.g., depth-groove-guided and index-guided techniques) are designed to improve preparation precision, the results are unsatisfactory because of the lack of proper estimating tools. This study proposed a novel technique, in which relevant details for preparation of drilling holes are provided and(More)
