Liver has a very amazing ability to regenerate from the remnant liver after injury or partial hepatectomy (PH). Carbohydrate metabolism plays a critical role in regeneration. Many signaling pathways are involved in the metabolism process. We analyzed the changes of proteins at 0-36 h after PH in rats using isobaric tags for relative and absolute quantitation (iTRAQ) coupled with LC-MS/MS-based ...

An experimental method has been developed to investigate the cellular responses to central nervous system (CNS) injury using the fruit-fly Drosophila. Understanding repair and regeneration in animals is a key question in biology. The damaged human CNS does not regenerate, and understanding how to promote the regeneration is one of main goals of medical neuroscience. The powerful genetic toolkit...

Abstract Degradation of raw water quality promoted the introduction GAC (granular activated carbon) filtration and ozonation into Korean drinking treatment facilities in 1994 order to cope with organic pollutants. This study focuses on evaluation organics reduction performance regenerated carbons using long-term operational data. Three at Busan were selected for this purpose. It was found that ...

Recent studies have demonstrated that mesenchymal stem cells (MSCs) combined with CD34+ hematopoietic/stem progenitor cells (HSPCs) can function as surrogate urinary bladder cells to synergistically promote multi-faceted bladder tissue regeneration. However, the molecular pathways governing these events are unknown. The pleiotropic effects of Wnt5a and Cyr61 are known to affect aspects of hemat...

Optic nerve regeneration was examined in goldfish radioautographically, as well as by a variety of behavioral measures of visual function. The rate of regeneration was markedly enhanced by increasing temperature above the ambient level (20 °C). The earliest functional indication of recovery was the appearance of an autonomic response to a change in illumination, then the ability to localize foo...

Saguaro cacti (Carnegiea gigantea) are long-lived and exhibit great variability in growth that makes age estimation problematic. A few single-site studies have focused on those locales where long-term data (e.g. 85 years) are available. Using a newly developed technique, 733 saguaros were sampled in three locales (Silverbell, Harcuvar, Kofa) across Arizona and their age structure reconstructed ...

A published set of downstream targets of MyoD defined in a well-controlled in vitro experiment was filtered for relevance to muscle regeneration using a 27-time-point in vivo murine regeneration series. Using interactive hierarchical and Bayes soft clustering, only a minority of the targets defined in vitro can be confirmed in vivo (approximately 50% of induced transcripts, and none of represse...

delayed neuronal death after seizure attack may be mediated by the induction of apoptosis-pathway. caspase-3, a mammalian cysteine protease, promotes apoptosis after some neurological disorders. neuron regeneration peptides (nrps) are small synthetic peptides that stimulate neural proliferation, migration, and differentiation with no apparent toxicity and high target specificity in cns. in the ...

background: since the treatments of long tracheal leisions are associated with some limitations, tissue enginered trachea is considered as an alternative option. this study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. methods: nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°c/min) ...

the following study aims to present an innovative approach for design. participatory design is the model of direct involvement of different social groups in the design from functional tools to environments, social institutions and businesses. diverse collection of practices has been developed to support this direct involvement by participatory design. people are invited to participate during di...
