Explicit physics-informed neural networks for non-linear upscaling closure: the case of transport in tissues [PDF]

open access: yes, 2021
In this work, we use a combination of formal upscaling and data-driven machine learning for explicitly closing a nonlinear transport and reaction process in a multiscale tissue. The classical effectiveness factor model is used to formulate the macroscale reaction kinetics. We train a multilayer perceptron network using training data generated by direct

Isolation and primary cultures of human intrahepatic bile ductular epithelium [PDF]

open access: yes, 1988
A technique for the isolation of human intrahepatic bile ductular epithelium, and the establishment of primary cultures using a serum- and growth-factor-supplemented medium combined with a connective tissue substrata is described.

Reactive Oxygen Species and Oxidative Stress in the Pathogenesis and Progression of Genetic Diseases of the Connective Tissue [PDF]

open access: yes, 2020
Connective tissue is known to provide structural and functional 'glue' properties to other tissues. It contains cellular and molecular components that are arranged in several dynamic organizations.

Histologic evaluation of bone healing of adjacent alveolar sockets grafted with bovine- and porcine-derived bone: a comparative case report in humans [PDF]

open access: yes, 2017

Commentaries on the publication entitled Evidence for continuity of interstitial spaces across tissue and organ boundaries in humans [PDF]

open access: yesarXiv, 2021
Interstitial connective tissues are one of the four basic types of animal tissue and continuously distributed throughout the body. Illustrated by the movements of the micron-sized particles across the defined tissue boundaries and the continuously distributions of the fluorescently stained hyaluronic acid within the fibrous tissues around blood vessels

Oxidative Stress and Human Skin Connective Tissue Aging

open access: yes, 2016
Everyone desires healthy and beautiful-looking skin. However, as we age, our skin becomes old due to physiological changes. Reactive oxygen species (ROS) is an important pathogenic factor involved in human aging.

Usefulness in daily practice of the Systemic Lupus Erythematosus Disease Activity Index 2000 scale and the Systemic Lupus Erythematosus Disease Activity Score index for assessing the activity of systemic lupus erythematosus

open access: yesRheumatology
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by high hetero­geneity of clinical manifestations and an uncertain prognosis. Although the mortality rate due to SLE has decreased significantly in recent decades, there is still a

Increase of cell surface vimentin is associated with vimentin network disruption and subsequent stress-induced premature senescence in human chondrocytes

open access: yeseLife, 2023
Accumulation of dysfunctional chondrocytes has detrimental consequences on the cartilagehomeostasis and is thus thought to play a crucial role during the pathogenesis of osteoarthritis(OA). However, the underlying mechanisms of phenotypical alteration in

Shape Programming in Entropic Tissues [PDF]

open access: yesarXiv, 2023
Epithelial morphogenesis, a signature problem of tissue biology and tissue mechanics, continues to inspire biologists and physicists alike. Many treatments focus on tissue fluidization, apical/basal ratio changes, or mechanical instabilities. In contrast to these approaches, shape-programmable materials, where the local lengths in the material change ...
