1Biorefinery of bacterial cellulose from rice straw:enhanced enzymatic saccharification by ionic liquid pretreatment显示文摘The pretreatment of rice straw is often used to enhance the hydrolysis. 1-allyl-3-methylimidazolium chloride([AMIM]Cl) is a kind of low viscous,nontoxic and recyclable ionic liquid. It was used to treat rice straw and improve the enzymatic hydrolysis of rice straw in this study. The factors influencing the pretreatment were as follows:the dosage of rice straw in [AMIM]Cl,crush mesh of rice straw,pretreatment temperature and time. After the pretreatment with a 3 %(the weight ratio of rice straw to ionic liquid) rice straw dosage in [AMIM]Cl at 110 ℃ for 1 h,the yield of reducing sugar of regenerated rice straw by 33 U/mL cellulase hydrolysis was 53.3 %,which was two times higher than that of un-treated rice straw(23.7 %) . More researches regarding straw biorefinery to bacterial cellulose are being performed in the lab and prospective results will be published in near future.Hong Feng Han Shifen 2011Engineering Sciences2011,9,4:7
2Effects of moxibustion on heat-shock protein 70 expression in the spinal cord and colonic mucosa in a rat model of ulcerative colitis显示文摘Pathological changes in the colon are closely associated with the spinal cord,and innervation of spinal cord can regulate cellular functions.Our previous studies verified that moxibustion protects and restores the colonic mucosa,but the mechanisms of action remain unknown.The present study observed the effects of moxibustion and salicylazosulfapyridine on expression of heat-shock protein 70(HSP70) and its mRNA in the spinal cord and colonic mucosa of ulcerative colitis rats.Results demonstrated that moxibustion and salicylazosulfapyridine increased HSP70 mRNA expression in the spinal cord and colonic mucosa of ulcerative colitis rats.The decreased transcriptional activity of HSP70 in the spinal cord and colonic mucosa might participate in damage to the colonic mucosa in ulcerative colitis rats.Moxibustion exerted protective effects on colonic mucosa by up-regulating HSP70 transcriptional activity in the spinal cord and colonic mucosa.Li Qi Yin Shi Luyi Wu Jingping Mu Linying Tan Xiaopeng Ma Huirong Liu Shifen Xu Huangan Wu 2010Neural Regeneration Research2010,5,22:3
