摘要:
Several endogenous genes have been identified in Escherichia coli, the overexpression of which increases recombinant peptide production. Increasing the copy number of aroB, aroK, proB, or crl increases the amount of a recombinant peptide produced by a host cell. Recombinant host cells comprising at least one chimeric genetic construct encoding a peptide of interest and at least one genetic modification that increases recombinant peptide production are provided as well as methods of using such recombinant host cells

Disrupting the expression of endogenous Escherichia host cell genes gcvA and spr provides mutant host cells having increased heterologous peptide production relative to control Escherichia host cells. Recombinant Escherichia host cells are provided as well as methods of using such host cells for heterologous peptide production.
摘要:
Short single chain peptides having affinity for a target surface often lack the binding durability required for certain commercial applications. One way to improve durability is to promote multivalent binding by linking together binding sequences using peptide linkers. However, the resulting single chain binding peptides often suffer from linker entropy. It has been discovered that the use of rigid peptide linkers when linking together multiple binding sequences enhances the binding affinity of the resulting single chain peptide.

Methods for avoiding handover failure are provided. The method includes determining, by a source Base Station (BS), to perform a handover of a User Equipment (UE); determining, by the source BS, whether a target BS connects with a user plane node serving the UE at the source BS; and releasing resources, when the target BS does not connect with the user plane node serving the UE at the source BS.
摘要:
A processor is disclosed and includes at least one core including a first core, and interrupt delay logic. The interrupt delay logic is to receive a first interrupt at a first time and delay the first interrupt from being processed by a first time delay that begins at the first time, unless the first interrupt is pending at a second time when a second interrupt is processed by the first core. If the first interrupt is pending at the second time, the interrupt delay logic is to indicate to the first core to begin to process the first interrupt prior to completion of the first time delay. Other embodiments are disclosed and claimed.
摘要:
A method and system to provide user-level multithreading are disclosed. The method according to the present techniques comprises receiving programming instructions to execute one or more shared resource threads (shreds) via an instruction set architecture (ISA). One or more instruction pointers are configured via the ISA; and the one or more shreds are executed simultaneously with a microprocessor, wherein the microprocessor includes multiple instruction sequencers.
摘要:
A method for detachment of a mobile set within the equivalent route area moving between the communication systems comprising steps of: during the detachment process is implemented between a mobile set and a service node in one communication system, the service node generates one or more messages and transmits it to the service nodes in one or more communication system within the ERA. If the message is transmitted to the service node within the ERA of only one communication system, this service node transmits this message or the message generated according to this message to the service nodes within the ERA of the other communication system. With the method proposed in present invention, when a mobile is detached from two or more communication systems which share the same ERA, the service nodes in all communication systems within the ERA can still correctly manage the relevant information on this mobile set.
摘要:
A condom of embodiments of the disclosed technology has a tip and base with cords connecting the two, creating portals where the urethra is exposed and fully capable of feeling abrasion with other objects. The base ring is oppositely disposed from the tip and an extreme other end of the condom. The base ring also extends circumferentially and in parallel to a largest circumference of the solid tip, when the cord extends perpendicularly to the largest circumference of the solid tip and the base ring. The largest circumference of the circle referred to herein, in embodiments of the disclosed technology, is a portion of the tip which is closest to the base ring.
摘要:
The present invention relates to a method of identifying compounds useful in inhibiting protein kinase-like endoplasmic reticulum protein kinase (PERK). The method comprises providing a first model comprising PERK active domains, where the said active domains are selected from the group consisting of the peptide spanning from amino acid residue Asp144 to amino acid residue Ser191 of SEQ ID NO: 1 and a peptide comprising the amino acid residue at position 7 of SEQ ID NO: 1, providing one or more candidate compounds, evaluating contact between the candidate compounds and the first model to determine which of the one or more candidate compounds have an ability to bind to and/or fit in the first model, and identifying the compounds which, based on said evaluating, have the ability to bind to and/or fit in the first model as compounds potentially useful for inhibiting PERK. The present invention further relates to compounds that can be used for inhibition of PERK, for example human PERK, and methods related to treatment of PERK-mediated diseases.
