Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. A protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.

Abstract: Viral infection has been suspected in the development of primary Sjögren's syndrome (pSS). Using a custom viral microarray, hepatitis delta virus (HDV) genomes and antigens were detected in minor salivary glands of patients with pSS. Expression of HDV antigens in healthy mice led to a Sjögren's syndrome-like pathogenesis characterized by a reduction in salivary flow, increase in lymphocytic foci, and the development of an autoantibody profile similar to HDV-positive patients. Also described herein is the detection of HDV in patients diagnosed with lymphoma. Expression of HDV antigen in healthy mice resulted in the development of tertiary lymphoid structures characteristic of the early stages of lymphoma. A sensitive, nested qPCR assay to detect HDV transcript and/or HDV genome in patient samples is also described.

Abstract: Chelating agents are often used in conjunction with stimulation operations in a subterranean formation to address the presence of certain metal ions therein. Hydrophobically modified chelating agents can be used to form metal-ligand complexes in a subterranean formation that can sometimes exhibit significantly different behavior than do their more water-soluble variants. Methods for treating a subterranean formation can comprise: providing a treatment fluid comprising a hydrophobically modified aminopolycarboxylic acid chelating agent, the chelating agent comprising an N-substitution having no carboxylic acid groups and about 6 carbon atoms or more; introducing the treatment fluid into a subterranean formation; and complexing metal ions in the subterranean formation with the chelating agent to form a metal-ligand complex.

Abstract: In order to reduce crosstalk effects, cables that carry contaminating signals can be routed using physically adjacent cables in pairs that carry replica signals of opposite polarity. Keeping the cables in close proximity will reduce loop area and will cause the magnetic fields induced by the wires carrying the paired signals to cancel. Accordingly, the crosstalk induced both by the differential and common-mode components of these two signals on any other medium or device cancel each other.

Abstract: Some embodiments provide reconfigurable web application firewall (WAF) functionality across a distributed platform. Specifically, the WAF function at each distributed platform server is customizable on a per customer and per inbound message basis. When a server receives an inbound message, the server identities the content or services of which specific customer are implicated by the inbound message. The server screens the inbound message for attacks using a first set of rules and policies defined as part of a production profile from a WAF instance defined by the specific customer while contemporaneously testing the inbound message against a second set of rules and polices defined as part of an audit profile from the same WAF instance. In this manner, the specific customer tests the audit profile rules and policies while still receiving the protections of the production profile rules and policies.

Abstract: Some embodiments provide a content delivery network (CDN) solution that affords the CDN control over those elements of customer content that are delivered by third parties. The CDN integrates a distributed set of monitoring agents. Each monitoring agent monitors the delivery performance of third parties to the region in which the agent operates. The CDN uses the performance monitoring information to dynamically manage the content tags to the third-party delivered elements of CDN-customer content. Specifically, a CDN server retrieves the parent page for requested CDN-customer content. The CDN server identifies the region from where the request originates and retrieves the logs from the monitoring agents monitoring from that region. The CDN server then modifies the base page by dynamically removing the tags to the third-party delivered elements that are reported in the monitoring agent logs as being unavailable, inaccessible, or underperforming in the identified region.
