Natural antioxidants such as polysaccharides with strong antioxidant activities are used to protect against oxidative damage, yet little is known so far about the antioxidant effects of litchi fruit polysaccharides. In the present study, four different polysaccharide-enriched fractions were isolated from litchi pulp tissue and partially purified by a stepwise method of ethyl alcohol (EtOH) prec...

AIM In the last decade, tissue engineering has undergone enormous expansion in the fields of regenerative medicine and dentistry. In response to mechanical and chemical injuries, the dentine-pulp complex possesses a regenerative ability due to a speci?c population of mesenchymal stem cells, which have been widely described in literature. The postnatal dental pulp also contains progenitor stem c...

This review describes medium and high molecular weight organic material found in wastewaters from pulp and paper industry. The aim is to review the versatile pollutants and the analysis methods for their determination. Among other pollutants, biocides, extractives, and lignin-derived compounds are major contributors to harmful effects, such as toxicity, of industrial wastewaters. Toxicity of wa...

Orange peel and pulp were analyzed for their proximate composition, water and oil holding capacity. Data showed that, orange peel and pulp had high amount of dietary fiber (74.87 and 70.64%, respectively) with high proportion of IDF, also it has high level of water and oil holding capacity. Biscuits prepared from blendes containing different proportion (0,5,15 and 25%) orange peel or pulp were ...

Introduction Quantification of carious lesions and measurement of the distance to the pulp is an important task in conservative dentistry. This information can improve identification of cases with the potential for maintaining pulp vitality and monitor treatment success of indirect pulp capping. In the procedure of indirect pulp capping the nearly exposed pulp is covered with a chemical (usuall...

the effect of bleaching with sodium hypochlorite, as one of the most important parameters in obtaining optimal alpha cellulose pulp from cotton linter was studied. in this respect, unbleached cotton linter pulp was prepared from parchin chemical industry co., bleached by hea sequence in ph=9, 11 and 13; and then its chemical structures properties such as alpha cellulose, degree of polymerizatio...
