Effect of Postmortem Time and Preservation Fluid on the Tensile Material Properties of Bovine Liver Parenchyma
… the tensile failure properties of human liver parenchyma at 48hrs postmortem, it is currently unknown how the material properties change between time of death and 48hrs postmortem. Therefore, the purpose of this study was to quantify the effects of postmortem degradation on the tensile material …

Diabetes-related ultrastructural and immunohistochemical changes in human salivary gland parenchyma and a study on a native scaffold obtained from salivary gland stroma
… patients is the regeneration of salivary parenchyma. A “Native Human Submandibular Gland Scaffold” (nHSMGS) was isolated from healthy submandibular glands, and was analyzed by light and electron microscopy and by histochemistry. Morphological examinations showed a fiber arrangement similar …

Effects of feeding level and diet composition on mammary growth in prepubertal lambs and mice
… heavier mammary glands, with greater amounts of parenchyma and fat pad and higher content of dry, fat-free parenchymal tissue compared to the mean of the remaining groups. Total gland weight was lower in group R, although weight of parenchyma was similar to groups A and G. Parenchyma made up a …

Aquaporin-4 mediates blood brain barrier permeability during endotoxemia
… the exchange of fluids and solutes between the parenchyma of the central nervous system (CNS) and perivascular spaces. We hypothesized that activation of AQP4 may mediate permeability of the CNS during systemic inflammation. Here, mice were i.v. injected with fluorescent tracers of low (1 kd) …

Long-Term T Cell Responses in the Ischemic Brain
… of systemic immune cells into the brain parenchyma. T lymphocytes, part of the adaptive arm of the immune response, are present bordering the infarct region within days after stroke. Accumulation of these cells in the early inflammatory phase peaks 3 to 4 days after stroke injury. …

Modeling and Optimization of Individualized Liver Contrast-enhanced CT Imaging
… utility of building a patient-informed hepatic parenchyma contrast enhancement prediction model using retrospective clinical images. This project was conducted in two parts: 1) constructing the patient-informed contrast enhancement prediction model using retrospective patient cases and prior …

Maintenance and function of antigen-specific CD4 T cells within the lung during tuberculosis
… lung-associated vasculature and not in the lung parenchyma as previously thought. However, the PD-1+ population that shares features with follicular helper (Tfh) and memory T cells is principally located within the lung parenchyma. This distribution can be largely explained by considering the TB …

The structure and mechanical behavior of bamboo and bamboo products
… of cellular solids. Bamboo tissue is made up of parenchyma and vascular bundles, consisting of sclerenchyma fibers and vessels; the structure can be thought of as a fiber reinforced composite. There is a radial gradient in the volume fraction of vascular bundles as well as the fraction of quite …

Characterizing the Biomechanical Response of Liver
… 24 tensile failure tests were performed on the parenchyma. It was determined that there were no statically significant differences between failure stresses and strains between the testing temperatures. To test the effects of freezing, tensile tests were performed on the parenchyma of a single …
