Background Several strategies have been previously applied for classifying cervical cytology cells, all pursuing a nucleus segmentation. Sanchez sets regions [1] using a simple threshold [2], a procedure broadly adapted to different techniques: a local adaptive segmentation nuclei procedure [3], seed growing [4], mathematical morphology [5], a Hough transform [6], and active contours [7]. Jantz...

Bone's microporosity plays important biological and mechanical roles. Synchrotron radiation micro-computed tomography (SR CT) is considered the gold standard when evaluating osteocyte lacunae, vascular channels and their three-dimensional (3D) distribution, yet it is a rather exclusive technique. Here, we explored nondestructive desktop micro-computed tomography (desktop CT) as an alternative...

A method of morphometric quantitative of the number of pseudopodia per individual basal cell and the ratio of the total cross-sectional area of the pseudopodia to the base area of the basal cell, using the transmission electron microscope, was developed. The diameters and areas of the bases of basal cells and the pseudopodia were also obtained. The number of pseudopodia per basal cell (N) and t...

OBJECTIVES The purpose of this study was to determine the anatomical characteristics of the fibular incisura of the tibia and the distal end of the fibula that form together the tibiofibular syndesmosis joint and to obtain the morphometric data in both genders. MATERIALS AND METHODS Current study has been performed on 35 dry adult tibia-fibula sets (22 males and 13 females). RESULTS 35% of ...

The black sea urchin (Arbacia lixula, Linnaeus, 1758) is a non-edible marine echinoderm of high ecological importance with the potential to affect communities. A. lixula were sampled monthly for one year from supralittoral fringe at two locations in Pagasitikos Gulf, north-western Aegean Sea. Morphometric characteristics exhibited significant spatiotemporal variation. population closer proximit...

PURPOSE This study was performed to determine the optimal tile size for the fractal dimension of the mandibular trabecular bone using a tile counting method. MATERIALS AND METHODS Digital intraoral radiographic images were obtained at the mandibular angle, molar, premolar, and incisor regions of 29 human dry mandibles. After preprocessing, the parameters representing morphometric characterist...

The effects of ethanol (90% and 95% concentration) preservation on the morphometric characteristics Clarias gariepinus Oreochromis niloticus were investigated. characters observed total length, standard head body depth, eye diameter, weight for period sixty-three (63) days. Samples first euthanized before taking after which samples individually preserved in separate bottles filled with respecti...

The purpose of this study was to determine the morphometric and meristic characteristics, growth Signal barb fish in Tasik river. method used research is a survey method. Morphometric characteristics Bodyweight (BW) ranges from 4-73 gr, Total Length (TL), Standard 6.3-15.5 mm (SL), Head (HL) 1.8-2.5, Snout (SL) 0.5, Dorsal Fin Height (DFH) 2.3, (DFL) 3-7, Eye Diameter (EM) 0.8, Tail Trunk (TTH)...
