We report a case of the Werdnig-Hoffmann disease in a 4-month-old male infant. The morphological study revealed perimysial fibrosis, variability in the size of muscle fibers, absence of target fibers, few central nuclei and normality in vessels, nerves and neuromuscular junctions. The morphometrical examination showed the existence of normal-sized and atrophic fibers in both fibrillar types, as...

On Kranjsko polje in central Slovenia, carbonate conglomerates have been dated to several Pleistocene glacial phases by relative dating based on the morphostratigrafic mapping and borehole data, and by paleomagnetic and 10Be analyses. To define how the age of conglomerates determines the geomorphological characteristics of karst surface features, morphometrical and distributive spatial analyses...

Method Current research comprised of histo-morphometrical study of 120 skin samples collected in horizontal and vertical orientations from anterior chest area and lateral chest areas of formalin embalmed human cadavers (n = 30). The quantitative fraction of dermal collagen and elastic fiber content was obtained by tissue-quant image analysis. Spearman correlation coefficient (r) was computed to...

The present study examined the efficacy of Ocimum basilicum extract, a natural herb, with antioxidant properties, against testicular toxicity induced by Lead, which is one of the most important toxic heavy metals. The intoxicated rats showed decreased cell proliferation was reflected by a decrease in Ki-67 expression, whereas the increase in apoptotic rate was associated with a decrease in the ...

The aim of the present study was analyze, by histological and morphometrical studies, mandibular glands of Melipona bicolor queens collected from monogynic and polygynic colonies and compare their level of development. The results showed that the glands ofphysogastric queens from monogynic colony present a higher level of activity in relation to the queens of polygynic colonies; this is explain...

This paper describes the occurrence of digenetic Rhipidocotyle santanaensis Lunaschi, 2004 in Brazil. This parasite was found in the liver, heart, gonads, intestine, pyloric caeca, stomach, swim bladder and cavity of Acestrorhynchus lacustris (Lütken, 1875) from the Batalha River, São Paulo State, with higher incidence in gonads and digestive tract. The parasite specimens found in this study sh...

Ichnology deals with the traces of prehistoric organisms and thus with the study of dinosaur footprints and tracks. This paper reports on a reliable and precise methodology developed to integrate high-resolution close range photogrammetry and range sensors for 3D surveys of dinosaur footprints. The 3D footprint and track models recovered here yield a great deal of accurate morphological and mor...
