Inflammatory injury to the pancreas results in regeneration of normal tissue and formation of metaplastic lesions of a ductal phenotype. These metaplastic ductal lesions (MDL) are called tubular complexes (TC), mucinous metaplasia, or pancreatic intraepithelial neoplasia. Because they are regularly found in chronic pancreatitis and pancreatic cancer, their formation is thought to represent a st...

The mechanisms that define the body pattern during development and regeneration are the object of major concern in developmental biology. To understand the process and sequence of antero-posterior pattern formation of planarian body regions during regeneration, regenerating organisms were treated with exogenous retinoic acid, which affects development and regeneration in other systems, and the ...

In this article we review the types of natural and synthetic materials that are being used in brain tissue engineering applications for traumatic brain injury and stroke. We analyse modifications of scaffolds including immobilizing drugs, growth factors and extracellular matrix molecules to improve central nervous system regeneration and functional recovery. This review attempts to outline the ...

We previously reported that nidogen is an extracellular matrix protein regulating Schwann cell proliferation and migration. Since Schwann cells play a critical role in peripheral nerve regeneration, nidogen may play a role in it via regulation of Schwann cells. Here, we demonstrate direct evidence that nidogen induces elongation of regenerative axon growth of adult sensory neurons, and that the...

context periodontal plastic surgery can help people improve their lives by addressing aesthetic parameters of their smile. much of what comprises a beautiful and appealing smile is influenced by emotion and personality; however, many structural elements of a smile can be improved through surgical intervention. evidence acquisition the end result often lends significant support to people who wis...

J/ψ production at forward and midrapidity at the Relativistic Heavy-Ion Collider (RHIC) is calculated within a previously constructed rate-equation approach accounting for both direct production and regeneration from c and c̄. The results are compared to experimental data. The observed stronger suppression at forward rapidity can be qualitatively explained by a smaller statistical regeneration c...

The rat optic nerve is a useful model for stem cell regeneration research. Direct injection into the rat optic nerve allows delivery into the central nervous system in a minimally-invasive surgery without bone removal. This technique describes an approach to visualization and direct injection of the optic nerve following minor fascial dissection from the orbital ridge, using a conjunctival trac...

Abstract The paper presents the results on rapid production of H 2 from CH 4 by its direct decomposition in a plasma-catalytic mode stimulated microwave irradiation (MWI) at 600°C. Methane was passed through bed iron-containing carbon adsorbent obtained gas coal characterized large dielectric loss tangent. Under MWI, intense breakdown effects with plasma generation appear surface iron–carbon sy...

Liver regeneration is a complex process, having evolved to protect animals from the consequences of liver loss caused by food toxins. We establish a computational 3D single-cell-based model of the liver lobule regenerating after intoxication by CCl4. In order to constitute a statistically representative liver lobule, we assemble information from light and confocal microscopy analyzed by an imag...

Central and peripheral neural injuries are traumatic and can lead to loss of motor and sensory function, chronic pain, and permanent disability. Strategies that bridge the site of injury and allow axonal regeneration promise to have a large impact on restoring quality of life for these patients. Engineered materials can be used to guide axonal growth. Specifically, nanofiber structures can mimi...
