The structure of the zona pellucida and the early interactions between human oocytes and spermatozoa were investigated in an in vitro fertilization program. Thirty-five mature (preovulatory) oocytes, 10 immature oocytes lacking a germinal vesicle, and 11 atretic oocytes which had not undergone fertilization at 10-20 hr after insemination were studied by(More)
AIMS Vascular calcification correlates with inflammation and plaque instability in a dual manner, depending on the spotty/granular (micro) or sheet-like/lamellated (macro) pattern of calcification. Modified lipoproteins trigger both inflammation and calcification via receptors for advanced lipoxidation/glycation endproducts (ALEs/AGEs). This study compared(More)
Atherosclerotic plaques have a high probability of undergoing rapid progression to stenosis, becoming responsible of acute coronary syndrome or stroke. Microcalcifications may act as enhancers of atherosclerotic plaque vulnerability. Considering that calcifications with a diameter smaller than 10 mm in paraffin embedded tissue are rather difficult to(More)
In order to study the three-dimensional topographic arrangement of the oocyte and zona pellucida, follicular cells and follicle microvasculature, this study applied alkali maceration methods for tissue exposure, the ruthenium red-detergent method for the extracellular matrix visualization, and the vascular corrosion cast technique to rabbits, guinea-pigs(More)
The surface micro-morphology of the zona pellucida (ZP) was investigated in 158 inseminated but unfertilized mature human oocytes derived from assisted reproduction trials (ART) by means of traditional scanning electron microscopy (SEM) techniques (gold coating and conductive staining methods) and saponin-ruthenium red-osmium tetroxide-thiocarbohydrazide(More)
Despite recent advances, mineralization site, its microarchitecture, and composition in calcific heart valve remain poorly understood. A multiscale investigation, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive X-ray spectrometry (EDS), from micrometre up to nanometre, was conducted on human severely(More)
The exposure of humans to erionite fibres of appropriate morphology and dimension has been unambiguously linked to the occurrence of Malignant Mesothelioma. For this reason, a detailed morpho-structural investigation through Electron Microscopy techniques has been performed on erionite samples collected at two different localities, Durkee (ED) and Rome(More)
The tubule-like cells (TLC) of the parietal layer of the Bowman's capsule of the renal corpuscle in normal male mice are provided with bundles of thin microfilaments (50-70 A). Moreover, the ultrastructural observations demonstrated that similar thin filaments (50-70 A) are located in the flattened cells of the parietal layer of the Bowman's capsule and in(More)
BACKGROUND Human mature oocytes are very susceptible to cryodamage. Several reports demonstrated that vitrification might preserve oocyte better than slow freezing. However, this is still controversial. Thus, larger clinical, biological and experimental trials to confirm this concept are necessary. The aim of the study was to evaluate and compare fine(More)
Neuroanatomy is considered to be one of the most difficult anatomical subjects for students. To provide motivation and improve learning outcomes in this area, clinical cases and neurosurgical images from diffusion tensor imaging (DTI) tractographies produced using an intraoperative magnetic resonance imaging apparatus (MRI/DTI) were presented and discussed(More)
