HIV-1 protease is a dimeric aspartic protease that plays an essential role in viral replication. To further understand the catalytic mechanism and inhibitor recognition of HIV-1 protease, we need to determine the locations of key hydrogen atoms in the catalytic aspartates Asp-25 and Asp-125. The structure of HIV-1 protease in complex with transition-state analog KNI-272 was determined by combin...

A comprehensive study pertaining to the emulsion liquid membrane (ELM) extraction process to enrich dilute aqueous solutions of silver salt is presented. The study has highlighted the importance and influence of membrane composition for maximizing the extraction of Ag+ ions. The liquid membrane was made up of Cyanex-302 as an extractant and the industrial solvent mainly consists of p...

폐리튬이온배터리를 고온에서 용융환원시키면 코발트, 니켈 및 구리 금속합금상을 얻을 수 있다. 이러한 금속합금상으로부터 금속을 분리회수하기 위한 공정을 개발하기 위해 혼합한 금속혼합물을 3% 과산화수소를 함유한 2 M 황산용액으로 침출하면 9.6%의 구리와 함께 코발트와 니켈이 모두 침출된다. 침출용액에서 Cyanex 301로 구리(II)가 선택적으로 추출되었으며, 30% 왕수로 구리(II)를 탈거했다. 구리가 분리된 여액에서 이온성액체인 ALi-SCN으로 Co(II)를 추출했으며, 15%의 암모니아용액으로 3단의 교차식 탈거를 통해 본 연구를 금속혼합물의 황산침출액에서 용매추출로 세 분리할 있는 제안했다.
Sports-related sudden cardiac arrest (SCA) is widely recognized in young competitive athletes, yet recent studies have shown it occurs most frequently middle-aged, recreational athletes. Few comprehensively described the incidence of sports-related SCA general population. To describe events 3 Canadian Provinces: Ontario, Saskatchewan, and British Columbia, with a combined estimated population 7...
Chronic stimulation of a predominantly fast skeletal muscle enhanced the expression of type I (slow muscle) Ca-ATPase and suppressed the expression of the type II (fast muscle) Ca-ATPase. Monoclonal antibodies IID8 and IIH11 against type I (slow) and type II (fast) isozymes respectively, were used to type the Ca-ATPases of the isolated SR (sarcoplasmic reticulum) by Western blots, and the Ca-AT...
