摘要:
In apparatus for separating the components of a mixture, the mixture is admitted to a first inlet which communicates with a working region which may be defined by a cylindrical tube. A fluid under pressure is admitted to a chamber through a second inlet. The chamber also communicates with the working region. The fluid forms a spiralling flow which draws the mixture into the working region in the form of a vortex. In the apparatus, the chamber communicates with the working region by way of a throat, and the mixture is conveyed from the working region along an outlet.

An apparatus and method are provided for clamping a belt with a quick clamping action. The apparatus and method employ an impact force applied to a clamping device that causes a clamping portion of the clamping device to be driven into clamping engagement with the belt received in a housing for the clamping device. In one form, the clamping device has a clamp actuator that includes an impact receiving end preferably disposed outside the housing and a clamp member in the housing that is driven into clamping engagement with the belt by the actuator. The preferred belt clamp has the actuator and clamp member configured so that during belt pulling operations, the clamp also self-locks onto the belt to increase the clamping force applied thereto. In another aspect, the housing preferably has wall portions of varying thickness to provide increased strength where needed while keeping the weight thereof to a minimum.

The present invention is directed toward inhibitors of antiplasmin cleaving enzyme for use in various therapies related to fibrin and α2-antiplasmin, and to substrates of APCE, which may be used, for example, in screening methods for identifying such inhibitors. The present invention is further directed to methods of treating or inhibiting atherosclerosis and thrombus disorders by altering the rations of types of plasma α2-antiplasmin.
摘要:
An apparatus and method for cryogenic processing comprising a chamber having a specially optimized configuration and geometry and having internal insert array of pathways and supporting elements to facilitate advanced materials processing. The pathways and supporting components can be configured by bending and positioning in different planes with bending the pathways with optimal radii and in different planes. The pathways bending radii can be within an optimal range for the size of the chamber and the angles between the pathway bending planes can be within an optimal range. The angles between the supporting components positioning planes and the pathway bending planes can be in an optimal range. The invention can also include structural supporting components that are attached at the pathway small movement points and the length of attachment can vary from about approximately zero to the full length of the supporting component. A space can be provided between pathway and supporting components or between the array and the chamber walls allowing their independent movement and product exchange
摘要:
Human α2-antiplasmin (α2AP) is the major inhibitor of the proteolytic enzyme plasmin that digests fibrin. Two forms of α2AP circulate in human plasma: a 464-residue protein, which we have termed “pro”-form, or α2APpro and an N-terminally-shortened 452-residue “activated”-form, or α2APact. The latter becomes crosslinked to fibrin by activated factor XIII about 5-fold more rapidly than α2APpro and makes fibrin resistant to digestion by plasmin. A new human plasma proteinase has been identified herein that cleaves the Pro12-Asn13 bond of α2APpro to yield α2APact. This enzyme is identified herein as Antiplasmin Cleaving Enzyme (APCE). Novel inhibitors of circulating APCE can diminish α2AP inhibitory capacity within forming fibrin or blood clots thereby making fibrin deposits or blood clots more susceptible to removal by plasmin. Patients who are susceptible to atherosclerotic plaque formation or are susceptible to developing thrombi that compromise organ function will benefit by therapies providing such inhibitors on a long term basis.
