Robust axon regeneration occurs after peripheral nerve injury through coordinated activation of a genetic program and local intracellular signaling cascades. Although regeneration-associated genes are being identified with increasing frequency, most aspects of regeneration-associated intracellular signaling remain poorly understood. Two independent studies now report that upregulation of cAMP i...
INTRODUCTION The use of guided tissue regeneration (GTR) techniques has been proposed as an adjunct to endodontic surgery in order to promote bone healing. Studies assessing the added benefits of GTR for the outcome of endodontic surgery are significantly variable in their treatment protocols, follow-up periods, and inclusion criteria, thus generating inconsistent and confusing results. The aim...
Hair cell death and regeneration on the three distal-most neuromasts in the posterior lateral line of zebrafish larvae were investigated after neomycin treatment. Treatment with ibuprofen, dexamethasone and salicylate examined the role of a normal inflammatory response on hair cell regeneration. Regeneration was observed 48 hours post-treatment indicating these reagents have no effect on the re...
The regeneration of an extreme dilution of bacteriophage in a large volume of broth, as described by Gratia and De Kruif, is due to the influence of partial anaerobiosis upon the regeneration of the principle. The influence of partial anaerobiosis upon regeneration of an extremely diluted bacteriophage was investigated in relation to different factors with the following results. 1. The See PDF ...
The epidemic of heart failure has stimulated interest in understanding cardiac regeneration. Evidence has been reported supporting regeneration via transplantation of multiple cell types, as well as replication of postmitotic cardiomyocytes. In addition, the adult myocardium harbors endogenous c-kit(pos) cardiac stem cells (eCSCs), whose relevance for regeneration is controversial. Here, using ...
Nerve regeneration conditioned fluid is secreted by nerve stumps inside a nerve regeneration chamber. A better understanding of the proteinogram of nerve regeneration conditioned fluid can provide evidence for studying the role of the microenvironment in peripheral nerve regeneration. In this study, we used cylindrical silicone tubes as the nerve regeneration chamber model for the repair of inj...
Axons of the mammalian CNS lose the ability to regenerate soon after development due to both an inhibitory CNS environment and the loss of cell-intrinsic factors necessary for regeneration. The complex molecular events required for robust regeneration of mature neurons are not fully understood, particularly in vivo. To identify genes affecting axon regeneration in Caenorhabditis elegans, we per...
Hepcidin is a key regulator of iron metabolism. The expression of hepcidin is significantly induced by iron overload, inflammation, and infection of pathogens. Recent studies have indicated that the expression of hepcidin in the liver is also regulated during liver regeneration. However, the mechanism of the regulation of hepcidin expression and its role in liver regeneration remain unclear. In...
