In the present paper X-ray microtomographic research of a molar tooth was conducted. The study revealed regions with a reduced mineral density in the vicinity of the fissure tip. The basic assumption investigated is that corrosion induced enamel mineral density decrease is enhanced by high tensile stresses generated by mechanical load on the occlusal surface of the tooth during crushing of food.

Multilayered and functionally graded coatings are extensively used for protection against wear of the working surfaces of mechanisms and machines subjected to sliding contact. The paper considers the problem of wear of a strip made of a functionally graded material, taking into account the heating of the sliding contact from friction. Wear is modeled by a moving strip along the surface of a hard abrasive in the form of a half-plane.

Article Synopsis
  • Current assessment methods for penile cavernous fibrosis in animal models are limited, prompting the study to evaluate micro-computed tomography (micro-CT) as a more effective alternative.
  • The study used 25 male rabbits with induced testosterone deficiency, assessing changes in penile samples over a period of 84 days through various analysis methods, including 3D modeling and tissue morphometry.
  • Results indicated that micro-CT provided detailed visualization and changes in tissue density, with significant alterations in smooth muscle/connective tissue and collagen ratios observed at different time points, suggesting a relationship between gray value changes and tissue reorganization in fibrosis.

Micro-CT visualization allows reconstruction of eye structures with the resolution of light microscopy and estimation of tissue densities. Moreover, this method excludes damaging procedures and allows further histological staining due to the similar steps in the beginning. We have shown the feasibility of the lab-based micro-CT machine usage for visualization of clinically important compartments of human eye such as trabecular outflow pathway, retina, iris and ciliary body after pre-treatment with iodine in ethanol.
