Using corrosion casts prepared with methyl methacrylate (MURAKAMI, 1971), the distribution of minute blood vessels in the thyroid gland of the dog, rat and rhesus monkey was observed with the scanning electron microscope. The blood capillaries derived from the interlobular or interfollicular arteries make a complex network encapsulating each follicle like a basket. In most follicles, capillarie...

According to the current view, the formation of new alveolar septa from preexisting ones ceases due to the reduction of a double- to a single-layered capillaries network inside the alveolar septa (microvasculature maturation postnatal days 14-21 in rats). We challenged this view by measuring stereologically the appearance of new alveolar septa and by studying the alveolar capillary network in t...

The blood vascular bed of the rat thyroid gland was reproduced by injection of a methacrylate casting medium and observed with a scanning electron microscope. The rat thyroid gland received the superior and inferior thyroid arteries and emitted the superior and inferior thyroid veins. Anastomosis between the interlobular arteries or between the interlobular veins was frequently observed in the ...

We report a 3D analysis of the neuronal circuits of human cerebral cortex. Neuronal circuits, which are essential for brain functions, are built up by neurons as a 3D network, so tracing the 3D neuronal network of human cerebral cortex is the first step to understanding the mechanism of human brain functions. The cortical microstructures were visualized by X-ray microtomographic imaging of adul...

For patients with extensive burns, wound coverage with an autologous in vitro reconstructed skin made of both dermis and epidermis should be the best alternative to split-thickness graft. Unfortunately, various obstacles have delayed the widespread use of composite skin substitutes. Insufficient vascularization has been proposed as the most likely reason for their unreliable survival. Our purpo...

The thermodynamic properties of fluid mixtures play a crucial role in designing physically meaningful models and robust algorithms for simulating multi-component multi-phase flow subsurface, which is needed many subsurface applications. In this context, the equation-of-state-based flash calculation used to predict equilibrium each phase given mixture going through splitting component, often bot...
