eight samples of flowering tops from six species of the genus crataegus l., commonly called hawthorn, from different geographic locations of iran were standardized according to german pharmacopoeia monograph on crataegi folium cum flore (hawthorn leaf with flower) by high-performance thin-layer chromatograph-ic (hptlc) fingerprinting combining with digital scanning profiling of their major poly...

conclusions expression levels of 1,426 genes were significantly up-regulated in the mutant compared to wt. furthermore, 301 genes were down-regulated with false discovery rates (fdr) of < 0.001 and absolute value of log2 ratio of ≥ 1. results a total of 4,182,944 and 4,182,021 clean tags were obtained from the wt and a nonpathogenic mutant stain (bct89), respectively, and 10,410 differentially ...

background and aims. the manufacturing process of rotary ni-ti file can influence its resistance to fracture. the rotary profile (dentsply-maillefer, baillagues, switzerland) is manufactured by grinding mechanism whereas twisted file (sybron endo, usa) is manufactured with a twisting method. the purpose of this study was to comparatively evaluate the effect of manufacturing process on distortio...

in this paper, by applying three functional operators the previous results on the(poisson) variance of the external profile in digital search trees will be improved. we study the profile built over $n$ binary strings generated by a memoryless source with unequal probabilities of symbols and use a combinatorial approach for studying the poissonized variance, since the probability distribution of...

PURPOSE To test and demonstrate measurement precision, imaging resolution, 3D thickness mapping, and clinical utility of a new prototype 3D very high-frequency (VHF) (50 MHz) digital ultrasound scanning system for corneal epithelium, flap, and residual stromal thickness after laser in situ keratomileusis (LASIK). METHODS VHF ultrasonic 3D data was acquired by arc-motion, meridional scanning w...

PURPOSE To examine epithelial and stromal layers by three-dimensional very high-frequency (VHF) digital ultrasound scanning before and after implantation of Intacs (intracorneal ring segments [ICRS]). METHODS Three-dimensional scanning was performed in five eyes before and 3 months after Intacs insertion. Digital signal processing techniques provided high-resolution B-scan imaging and I-scan ...
