Despite the capacity of Schwann cells to support peripheral nerve regeneration, functional recovery after nerve injuries is frequently poor, especially for proximal injuries that require regenerating axons to grow over long distances to reinnervate distal targets. Nerve transfers, where small fascicles from an adjacent intact nerve are coapted to the nerve stump of a nearby denervated muscle, allow for functional return but at the expense of reduced numbers of innervating nerves. A 1-hour period of 20 Hz electrical nerve stimulation via electrodes proximal to an injury site accelerates axon outgrowth to hasten target reinnervation in rats and humans, even after delayed surgery. A novel strategy of enticing donor axons from an otherwise intact nerve to grow through small nerve grafts（cross-bridges） into a denervated nerve stump, promotes improved axon regeneration after delayed nerve repair. The efficacy of this technique has been demonstrated in a rat model and is now in clinical use in patients undergoing cross-face nerve grafting for facial paralysis. In conclusion, brief electrical stimulation, combined with the surgical technique of promoting the regeneration of some donor axons to ‘protect＇ chronically denervated Schwa nn cells, improves nerve regeneration and, in turn, functional outcomes in the management of peripheral nerve injuries.

In this study, inhibition of tall oil fatty acid hydrodeoxygenation(HDO) activity due to addition of rosin acid over sulfided Ni Mo/Al_2O_3 was investigated. Oleic acid and abietic acid were used as model compounds for fatty acid and rosin acid respectively in tall oil. After completion of each HDO experiment,the Ni Mo catalysts were recovered and used again under the same conditions. The results showed that the oleic acid HDO activity of sulfided catalysts was inhibited by addition of abietic acid due to competitive adsorption and increased coke deposition. The rate of carbon deposition on the catalysts increased when abietic acid was added to oleic acid feed. Moreover, the coke was in a more advanced form with higher stability for the catalysts exposed to both oleic acid and abietic acid. Furthermore, a clear correlation between the rate of coke formation and concentration of abietic acid was observed.

This short article explores the meaning of Shusterman＇s ＂transactional body,＂ derived from his statement that the will is not a purely mental affair that is independent of physical modality but is always an interaction with its environment. While he appreciates the Deweyan interaetional model, he develops the ＂transactional mode,＂ which he implies should expand the body-mind unity to the level of social and cultural conditions. Shusterman finds similar integrations and transactions among the mental, psychophysical and physical levels in Asian philosophical traditions. This article conducts a comparative study between his theory and Mencius＇ understanding of the body. Within the discussion, the analysis of aesthetic experience explicated by Dewey and Shusterman is reviewed as the link to the comparison.

Across the African continent efforts to intensify agriculture have been limited to specific commodities,locations or particular production *** causes for the widespread failure to overcome low land and labor productivity while maintaining ecosystem services have often be analyzed but remain poorly understood.A socialecological system approach may help to better understand the complex nature of ecological disadvantages,postcolonial structures,limited connect between producers and consumer markets,low off-farm livelihood opportunities,partial underpopulation and lacking experience with the concept of sustainable production as a major impediment for sustainable intensification of the agricultural ***,recent success stories in agro-pastoral systems as well as urban vegetable and animal production and associated value chains in West Africa,and in intensive mixed-cropping systems of the Great Lakes Region show the potential of stakeholder-driven agricultural *** interpretation of these cases may provide lessons for a more widespread eco-intensification of smallholder agriculture in sub-Saharan Africa.

Preconditioning stimulus：Preconditioning is an adaptive response,whereby a small dose of a harmful substance protects the brain from a subsequent damaging insult（Dirnagl et al.,2009）.The concept of preconditioning was first described in an ischemic heart model,it was observed that brief ischemic episodes protect against a subsequent ischemic insult（Murry et al., 1986）.
