    • The present invention provides methods for identification of methylated, and/or potentially methylatable CpG dinucleotides in genomic DNA sequences, and methods for isolating genomic DNA sequences comprising methylated CpG dinucleotide sequences. The present invention further provides methods for comparison of the methylation status of specific CpG dinucleotides, and patterns thereof between normal and diseased genomic DNA sequences, along with methods for determining all potentially methylatable CpG dinucleotides in a genomic DNA sample. Specifically, the present invention discloses a novel use of 5-methylcytosine DNA glycosylase (5-MCDG) in combination with art-recognized DNA base excision repair (BER) enzymes, and in particular embodiments, in combination with DNA methyltransferase to specifically label methylated CpG dinucleotide sequences in genomic DNA sequences.
    • 本发明提供用于鉴定基因组DNA序列中甲基化和/或潜在可甲基化CpG二核苷酸的方法,以及用于分离包含甲基化CpG二核苷酸序列的基因组DNA序列的方法。 本发明还提供了用于比较特定CpG二核苷酸的甲基化状态及其在正常和患病基因组DNA序列之间的模式的方法,以及用于确定基因组DNA样品中所有潜在可甲基化CpG二核苷酸的方法。 具体地,本发明公开了5-甲基胞嘧啶DNA糖基化酶(5-MCDG)与本领域公认的DNA碱基切除修复(BER)酶的组合的新用途,并且在具体实施方案中,与DNA甲基转移酶组合以特异性标记甲基化CpG 基因组DNA序列中的二核苷酸序列。

    • An implantable defibrillator, which may include cardioversion and pacemaker capabilities, which has EMI filters which are not susceptible to defibrillation shocks and which reduce or eliminate the effects of charging noise on sensing circuits used for continuous confirmation. A first filter capacitor is provided between a sense electrode, which may include pacing capabilities, and a ground reference within a hermetically sealed can containing a pulse/shock generator. A second filter capacitor is provided between a sensing/pacing reference electrode, which may also be a high voltage or shock electrode, and the ground reference. In addition, there is a third filter capacitor between the ground reference and the can. Preferably, the connections of the first, second and third filter capacitors are physically as well as electrically adjacent to each other. The filter capacitors are housed in the can and in or adjacent to a feedthrough assembly which passes through the can. Most preferably, the filter capacitors are discoidal capacitors mounted in or adjacent to the feedthrough.
    • 可植入除颤器,其可以包括心脏复律和起搏器功能,其具有不易于除颤冲击的EMI滤波器,并且其减少或消除了用于连续确认的感测电路上的充电噪声的影响。 第一滤波电容器设置在可包括起搏能力的感测电极和包含脉冲/冲击发生器的密封罐内的接地基准之间。 在感测/起搏参考电极(也可以是高电压或冲击电极)和接地参考之间提供第二滤波电容器。 另外,接地参考和罐之间有一个第三个滤波电容。 优选地,第一,第二和第三滤波电容器的连接在物理上以及彼此电气相邻。 滤波电容器容纳在罐中并且位于或靠近通过罐的馈通组件。 最优选地,滤波电容器是安装在馈通或邻近馈通的盘形电容器。
