BACKGROUND Acupuncture has been used for the enhancement of functional recovery from various disorders. In the present study, the effect of acupuncture on the apoptosis and new cell proliferation in the hippocampal dentate gyrus of gerbils (n = 25) following transient global ischemia was investigated. METHODS To determine the level of apoptosis and cell(More)
Nine algorithms were implemented to overcome the problem associated with rendering high-dynamic-range scientific imagery to low-dynamic-range display devices. The algorithms were evaluated using two paired-comparison psychophysical experiments judging preference and " scientific usefulness ". The results showed that, on average, the Zone System algorithm(More)
This research integrates the techniques used for the display of high dynamic range pictorial imagery for the practical visualization of non-pictorial (scientific) imagery such as remote sensing, medical imaging, astronomical imaging, etc. for data mining and interpretation. Nine algorithms were utilized to overcome the problem associated with rendering high(More)
OBJECTIVES To evaluate the inhibitory effect of ursolic acid (UA)-containing composites on Streptococcus mutans (S. mutans) biofilm. MATERIALS AND METHODS Composite resins with five different concentrations (0.04, 0.1, 0.2, 0.5, and 1.0 wt%) of UA (U6753, Sigma Aldrich) were prepared, and their flexural strengths were measured according to ISO 4049.

In order to identify response predictors for a post-operative glioblastoma therapy consisting of tamoxifen, carboplatin and radiotherapy, expression of 12 antigens was evaluated in 36 newly diagnosed tumours and 13 recurrences. Results were correlated with the clinical course of the disease. Antigen expression was assessed immunohistochemically for CD44s,(More)
