Over that period, IBM has continued to update both the hardware and software, providing added features, higher performance, greater physical security, and improved management features. This commitment continues with the System z9e, as demonstrated by(More)
A 54-year-old neurotic patient developed pyridostigmine-induced proximal weakness with daily 3600 mg of pyridostigmine. Detailed analysis of the RNS test showed three different types of responses which were reproduced in the in vitro nerve-muscle preparation, confirming that three different responses represent the different degree of pyridostigmine(More)
