苯酚在内蒙古粘土上的吸附

对苯酚在内蒙古粘土上的吸附进行了研究，测定了吸附等温线和吸附动力学，观察了pH值和离子强度等因素对吸附量的影响．结果表明：苯酚的吸附速率符合一级动力学规律；苯酚的吸附等温线符合hangmulr等温式，降低pH值和增加离子强度使苯酚在该土壤上的吸附量明显减小．     

胆源性急性胰腺炎119例诊治体会

目的:探讨胆源性急性胰腺炎的诊断和手术时机,方法:对1995年7月至2005年5月收治的胆源性急性胰腺炎(BAP)119例进行前瞻性分析,随机分为早期手术治疗组43例和保守治疗组76例,结果:入院后1w内行急诊手术43例,死亡3例,治愈40例,保守治疗组76例,晚期手术63例(保守治疗2～3w后),死亡3例,13例未行手术出院,结论:BAP(2w内)一般均可保守治疗,重型胆源性胰腺炎应在发病后3～4w炎症控制良好,病情稳定后再及时手术,可以缩短住院时间,减少并发症,降低手术死亡率。

Simultaneous mineralization of CO2 and recovery of soluble potassium using earth-abundant potassium feldspar

CO2 capture and storage(CCS) is an important strategy in combatting anthropogenic climate change.However,commercial application of the CCS technique is currently hampered by its high energy expenditure and costs.To overcome this issue,CO2 capture and utilization(CCU) is a promising CO2 disposal method.We,for the first time,developed a promising method to mineralize CO2 using earth-abundant potassium feldspar in order to effectively reduce CO2 emissions.Our experiments demonstrate that,after adding calcium chloride hexahydrate as an additive,the K-feldspar can be transformed to Ca-silicates at 800 C,which can easily mineralize CO2 to form stable calcium carbonate and recover soluble potassium.The conversion of this process reached 84.7%.With further study,the pretreatment temperature can be reduced to 250 C using hydrothermal method by adding the solution of triethanolamine(TEA).The highest conversion can be reached 40.1%.The process of simultaneous mineralization of CO2 and recovery of soluble potassium can be easily implemented in practice and may provide an economically feasible way to tackle global anthropogenic climate change.

PTC124 targets genetic disorders caused by nonsense mutations

Nonsense mutations promote premature translational termination and cause anywhere from 5-70% of the individual cases of most inherited diseases. Studies on nonsense-mediated cystic fibrosis have indicated that boosting specific protein synthesis from <1% to as little as 5% of normal levels may greatly reduce the severity or eliminate the principal manifestations of disease. To address the need for a drug capable of suppressing premature termination, we identified PTC124-a new chemical entity that selectively induces ribosomal readthrough of premature but not normal termination codons. PTC124 activity, optimized using nonsense-containing reporters, promoted dystrophin production in primary muscle cells from humans and mdx mice expressing dystrophin nonsense alleles, and rescued striated muscle function in mdx mice within 2-8 weeks of drug exposure. PTC124 was well tolerated in animals at plasma exposures substantially in excess of those required for nonsense suppression. The selectivity of PTC124 for premature termination codons, its well characterized activity profile, oral bioavailability and pharmacological properties indicate that this drug may have broad clinical potential for the treatment of a large group of genetic disorders with limited or no therapeutic options.
