摘要:这项研究的主要目的是确定也门风湿性心脏病的患病率.在1997年10月至1998年3月期间,对5000名年龄在5至18岁之间的学童(2504名女性和2496名男性)进行了一项前瞻性集群抽样筛查研究.疑似病例接受了心电图,胸部x光和多普勒超声心动图检查.尽管未发现活动性风湿热病例,但有12名女孩和6名男孩患有该疾病,患病率为每千人3.6例,高于邻国的报道.所有确诊和疑似病例每3周按体重给予苄青霉素g,先进行试验剂量.风湿热的预防计划,以及预防链球菌喉部感染,是未来的目标.

摘要:The present disclosure relates to the synthesis of Vitamin K2 bearing varying prenyl side chains. The synthesis comprises the reaction of phenyl sulfone of tert-butyl dimethyl silyl (TBDMS) protected mono prenyl menadiol with prenyl halides bearing varying prenyl units in the presence of the phase transfer catalyst followed by reductive desulphonation to yield TBDMS ether of Vitamin K2. The TBDMS ether is then oxidized in the presence of chromium trioxide and periodic acid to yield the corresponding Vitamin K2.
