Appendage regeneration is defined by rapid changes in gene expression that achieve dramatic developmental effects, suggesting involvement of microRNAs (miRNAs). Here, we find dynamic regulation of many miRNAs during zebrafish fin regeneration. In particular, miR-133 levels are high in uninjured fins but low during regeneration. When regeneration was blocked by Fibroblast growth factor (Fgf) rec...

State of health (SOH) prediction in Li-ion batteries plays an important role in intelligent battery management systems (BMS). However, the existence of capacity regeneration phenomena remains a great challenge for accurately predicting the battery SOH. This paper proposes a novel prognostic framework to predict the regeneration phenomena of the current battery using the data of a historical bat...

The ability to fully restore damaged or lost organs is present in only a subset of animals. The Xenopus tadpole tail is a complex appendage, containing epidermis, muscle, nerves, spinal cord, and vasculature, which regenerates after amputation. Understanding the mechanisms of tail regeneration may lead to new insights to promote biomedical regeneration in non-regenerative tissues. Although chro...

PURPOSE To evaluate the effect of diabetes on rhodopsin regeneration in the excised mouse eye. METHODS A superfused excised mouse eye preparation that exhibits rhodopsin regeneration after moderate bleaches and that is responsive to the composition of the perfusate was used. Diabetes was induced in albino mice (BALB/c) with the diabetogenic agent streptozotocin. Absorption spectrophotometry o...

a common cause of peripheral nerve injury is trauma. the positive effect of antioxidants on the improvement of nerve regeneration has currently become a focus of attention. in this experiment, the effect of intraperitoneal administration of ubiquinone (coq10) on an acute experimentally sciatic nerve crush was studied in a rat model. forty-five male wistar rats, weighing between 160-180 g were u...

the purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (af) on a cross section of rat sciatic nerves. thirty adult male sprague-dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or af (n=10), (2) normal saline or ns (n=10), and (3) sham surgery (n=10). the af was aspirated from the amniotic cavity of incubat...

who recommends artemisinin-based combination therapies (acts) as the most effective choice to treat malaria. for developing transgenic plants with high accumulation of artemisinin (by introducing genes encoding enzymes which regulate the biosynthetic pathway of artemisinin), an efficient protocol for tissue culture and plant regeneration is necessary. in the present study, leaf explants of arte...

human adipose tissue represents an abundant, practical and appealing source of donor tissue for autologous cell replacement. recent findings have shown that stem cells within the stromalvascular fraction of adipose tissue display a multilineage developmental potential. adipose tissue-derived stem cells can be differentiated towards adipogenic, osteogenic, chondrogenic,myogenic and neurogenic li...

Appendage regeneration is one of the most compelling phenomena in regenerative biology and is extensively studied in axolotls and newts. However, the regenerative capacity in other families of salamanders remains poorly described. Here we characterize the limb regeneration process in Bolitoglossa ramosi, a direct-developing terrestrial salamander of the plethodontid family. We (1) describe the ...
