"We expect oil demand will be around 2 million barrels per day more in 2005 versus the average in 2004, so we need something like 3 million barrels per day of additional capacity globally to avoid another year of high prices," Mandil told Reuters on the eve of the 19th World Energy Congress in Sydney.

&我们预计,与2004年的平均水平相比,2005年的石油日需求量会再增加200万桶左右,因此,我们需要在全球范围内把石油日产量再额外提高300万桶左右,以避免下一年再度出现价格过热的现象。&

A potential approach to this problem is to make use of a natural defense mechanism called " the stress response," which is characterized by a transient down - regulated synthesis of nonvital cellular proteins and increased production of endogenous protective factors known as heat shock proteins that act to allow proper refolding of proteins denatured by the incipient injury.

应激反应的特征是一过性下调细胞非必需蛋白的合成及增加被称为热休克蛋白的内源性保护因子的合成。热休克蛋白作用是促使损伤导致变性的蛋白适当地再折叠。HSP家族中HSP70被认为在细胞保护中发挥重要作用。
