Abstract The paper describes a theoretical study and exploration of authors in the field biomechanics. lung parenchyma is focused, its elastic behaviour under physiological mechanical load, pressure change during breathing. Anatomical view to human respiratory system generally introduced first together with more detailed description alveolus. Then appropriate theory elaborated, aimed on mathema...

Using a new NMR correlation-peak imaging technique, we were able to investigate noninvasively the spatial distribution of carbohydrates and amino acids in the hypocotyl of castor bean seedlings. In addition to the expected high sucrose concentration in the phloem area of the vascular bundles, we could also observe high levels of sucrose in the cortex parenchyma, but low levels in the pith paren...

Computer-aided diagnosis (CAD) system provides effective early lung diseases diagnoses. Parenchyma refers to the part Lung that is responsible for that Lung working properly. People with lung parenchymal disease often suffer from conditions such as sarcoidoisis, characterized by tissue swelling and the formation of lumps in the tissue. Other conditions commonly found in the lung’s parenchyma ar...

The intralobar and subcapsular areas of human liver were compared in terms of morphometry and morphology, and a correlation was made between the thickness of liver capsules and the amount of intralobar non-parenchyma in normal and diseased livers. Tissue was systematically sampled from 16 normal and 26 fibrotic livers taken at necropsy. The volume fraction of subcapsular and intralobar non-pare...

In transverse orientation, maize (Zea mays) roots are composed of a central stele that is embedded in multiple layers of cortical parenchyma. The stele functions in the transport of water, nutrients, and photosynthates, while the cortical parenchyma fulfills metabolic functions that are not very well characterized. To better understand the molecular functions of these root tissues, protein- and...

Sapwood respiration often declines towards the sapwood/heartwood boundary, but it is not known if parenchyma metabolic activity declines with cell age. We measured sapwood respiration in five temperate species (sapwood age range of 5-64 years) and expressed respiration on a live cell basis by quantifying living parenchyma. We found no effect of parenchyma age on respiration in two conifers (Pin...
