摘要: The present invention provides nucleic acid molecules, DNA constructs, plasmids, and methods for post-transcriptional regulation of gene expression using RNA molecules to both repress and activate translation of an open reading frame. Repression of gene expression is achieved through the presence of a regulatory nucleic acid element (the cis-repressive RNA or crRNA) within the 5′ untranslated region (5′ UTR) of an mRNA molecule. The nucleic acid element forms a hairpin (stem/loop) structure through complementary base pairing. The hairpin blocks access to the mRNA transcript by the ribosome, thereby preventing translation. In particular, in embodiments of the invention designed to operate in prokaryotic cells, the stem of the hairpin secondary structure sequesters the ribosome binding site (RBS). In embodiments of the invention designed to operate in eukaryotic cells, the stem of the hairpin is positioned upstream of the start codon, anywhere within the 5′ UTR of an mRNA. A small RNA (trans-activating RNA, or taRNA), expressed in trans, interacts with the crRNA and alters the hairpin structure. This alteration allows the ribosome to gain access to the region of the transcript upstream of the start codon, thereby activating transcription from its previously repressed state.
摘要翻译: 本发明提供核酸分子,DNA构建体,质粒和用于转录后调节基因表达的方法,其使用RNA分子抑制和激活开放阅读框的翻译。 通过在mRNA分子的5'非翻译区(5'UTR)内存在调节性核酸元件(顺式抑制性RNA或crRNA)来实现基因表达的抑制。 核酸元件通过互补碱基配对形成发夹(茎/环)结构。 发夹阻止核糖体进入mRNA转录物,从而阻止翻译。 特别地,在设计用于在原核细胞中操作的本发明的实施方案中,发夹二级结构的茎螯合核糖体结合位点(RBS)。 在设计用于在真核细胞中操作的本发明的实施方案中,发夹的茎位于起始密码子的上游,位于mRNA的5'UTR内的任何位置。 以反式表达的小RNA(反式激活RNA或taRNA)与crRNA相互作用并改变发夹结构。 这种改变允许核糖体进入起始密码子上游的转录物区域,从而从其先前的抑制状态激活转录。

摘要: A battery movement, storage, and charging system for large size batteries used in lift trucks includes spaced, parallel storage racks, each of which have multiple storage and charging bays. A battery transport tower is positioned in an aisle between the storage racks and is moveable horizontally between the two rows of racks. The tower includes an extendable fork lift mounted which may rotate around the axis of the tower as well as move vertically upwardly or downwardly on the tower. A battery exchanger loads a discharged battery from a lift truck, places it on a pallet and then transfers the pallet and battery to a transfer bay in a storage rack where the tower forklift moves a pallet and battery to a selected charging bay.

摘要: A process challenge device and method of using the same is presented for testing the efficiency of various sterilization procedures on objects to be sterilized. The device is assembled from two tapered end portions having opposite open ends and an open pathway extending therethrough. A central chamber in the open pathway receives a Biological Indicator for testing the efficiency of the sterilization process. The device is ideal for testing a sterilization process on elongated objects such as tubing, at any point along their length. The coupling structures on the end portions provide the device with single-use security.
