In one embodiment, a system can comprise an interface that receives data related to a communication session and a messaging security device component that evaluates the data and enables a security measure for preventative monitoring of a threat based on the evaluation, the security measure can be universally applied to two or more messaging formats.
摘要:
The present invention relates to methods of producing a polypeptide having biological activity in a bacterial cell, comprising: (a) cultivating a bacterial host cell in a medium conducive for production of the polypeptide, wherein the bacterial host cell comprises a nucleic acid construct comprising a promoter region operably linked to a polynucleotide sequence encoding the polypeptide and a modified mRNA processing/stabilizing sequence located downstream of the promoter region and upstream of the ribosome binding site of the polynucleotide sequence encoding the polypeptide, wherein the modified mRNA processing/stabilizing sequence promotes higher expression of the polynucleotide sequence compared to an unmodified mRNA processing/stabilizing sequence; and (b) isolating the polypeptide having biological activity from the cultivation medium. The present invention also relates to such modified mRNA processing/stabilizing sequences, nucleic acid constructs, and bacterial host cells and to methods of obtaining such bacterial host cells.

An automated, highly sensitive, specific and potentially quantitative detection method using an automated microscope for identifying and enumerating rare cancer cells in blood and other fluids.
摘要:
A method for managing access to a confined space which is cooled by the direct injection of a cryogenic fluid, comprising at least one system for closing the confined space, which can prevent access to said confined space and can be opened/closed to a variable and controllable degree, and a data acquisition and processing device. The device can: control the open or closed state of the closure system; set and control the degree to which the closure system is open/closed; ensure that a time delay (TP) is respected every time the closure system is closed, after which time delay the injection of cryogenic fluid into the space resumes; and, at the request of a user, implement the cycle for opening the closure system. The device determines the time that has elapsed (TE) in the closed position since the last closure cycle of the closure system and compares TE to TP. If TE=TP the device immediately authorizes the opening of the closure system. If TE>TP the device authorizes the opening of the closure system after a predefined waiting time.
摘要:
An intramedullary fixation device and related method for treatment of a Jones fracture. An exemplary device may comprise a rod having a distal section and a threaded proximal section, and means for securing the distal section within a first bone portion on a distal side of a fracture site. The device may also comprise a compression collar threadably received over the proximal section for providing compression to the fracture site, the compression collar comprising a threaded portion on its exterior surface configured to engage an interior of a second bone portion on a proximal side of the fracture site. In addition, the device includes an anti-rotational system engaging the compression collar to prevent rotation of the compression collar from its position providing the compression to the fracture site.
摘要:
An filter, apparatus and method for preparing microscope slides is presented. After filtration of the specimen is performed, the filter containing the filtrand is configured to be microscopically examined. The filter may either be affixed to a microscope slide or, in an embodiment, the filter may be incorporated into a microscope slide.
摘要:
An orthopedic fixation system having two rings or other base/frame elements separated by a plurality of struts. The struts are attached to the rings by a combination of a attachment mechanism having at least two degrees of movement each, and at least one connecting mechanism. The connecting mechanisms may be moveably or non-moveably connected to one or more tracks located on either or both rings of base elements. A combination of these elements provides a fixation device that allows for six degrees of freedom of movement between the rings or other base elements.
摘要:
The present invention relates to a plasma generating device having a first and a second electrode (3, 4) which are at a spacing from each other for generating a plasma (13) between the two electrodes (3, 4), a dielectric (8) which is disposed between the two electrodes (3, 4), a gas inlet (10) in the space between the two electrodes (3, 4) for supply of a plasma generating gas (12), one of the two electrodes (3, 4) having at least one opening (5) as gas outlet from the space between the two electrodes (3, 4), through which the plasma (13), which can be generated between the two electrodes (3, 4), can be expelled parallel to the direction of the electrical field which can be produced by the two electrodes (3, 4) between the two electrodes (3, 4), a grating, net and/or fabric (1) being disposed across the cross-section of the at least one opening (5).
