The chemical regeneration of granular activated carbon exhausted in a petrochemical wastewater unit was investigated. Gas chromatography and energy-dispersive X-ray spectroscopy demonstrated that spent activated carbon carries large types of organic and inorganic materials. Diverse chemical solvents were adopted in comparison with traditional chemical solvents and regeneration efficiency was in...

Conventional methods of pear breeding, largely based on intra- and inter-specific hybridization, are difficult because pear is highly heterozygous, polygenic and has a long juvenile period. Genetic improvements of pear cultivars are possible through induction of mutations and gene transfer by genetic engineering. A general prerequisite for these approaches is to establish an efficient plant reg...

central nervous system axons fail to regenerate after spinal cord injury (sci), partially due to the accumulation of extracellular matrix molecules in the lesion and formation of the glial scar. depakine, as known as histone deacetylase inhibitor, has neuroprotective effects. this study evaluated the histological changes (cavitation and axon regeneration) after sci associated with (following ad...

strawberry is a valuable, nutritious, and economically important fruit all over the world including bangladesh. therefore, there is a demand to develop a suitable variety of strawberry. for this purpose, leaf explants from in vitro grown strawberry plantlets were cultured onto ms medium supplemented with different concentrations and combinations of 2,4-d, naa and ba for callus induction. the mo...

objectives : stem cell (sc) therapy is a promising technique for tissue regeneration. this study aimed to compare the viability and proliferation ability of periodontal ligament stem cells (pdlscs) isolated from the periodontium of healthy and periodontitis-affected teeth to obtain an autologous, easily accessible source of scs for tissue regeneration in periodontitis patients. materials and me...

objective: the aim of present study was to evaluate the quality, density and thickness of newly formed bone in experimental defects treated with combi-pack®, bio-oss® and biostite®. materials and methods: eight new zealand white rabbits were included in this randomized,blinded study. four equal 3×6 mm bone defects were created on the frontal and parietal bones of each animal and three were imme...

direct regenerations by using mature cotyledonary node as a explants has been shown to be time-saving and convenient strategy for micropropagation of soybean. so we have evaluated regeneration protocol through single shoot using cotyledonary node as a rapid and efficient protocol for two soybean cultivars and one mutant line. cotyledonary nodes explants obtained from 7-days-old in vitro seedlin...
