Abstract:
Techniques and systems are disclosed for measuring arterial transit delay using pseudo- continuous arterial spin labeling (ASL) with variable TR and interleaved post-labeling delays. In one aspect, a magnetic resonance imaging method for measure arterial blood flow and transit delay using arterial spin labeling (ASL) includes applying an ASL pulse sequence. The ASL pulse sequence includes a pre- saturation pulse, and a labeling pulse. The method includes performing data acquisition to measure a transit delay, which represents a time needed for labeled blood to arrive in an imaging slice.
Abstract:
The present invention is directed to inhibiting amyloidogenic processing of amyloid precursor protein, and/or inhibiting production of amyloid beta peptides. These methods can involve accelerating cis/trans isomerization of amyloid precursor protein at a phosphorylated serine/threonine-proline motif and/or contacting a cell with a compound that mimics the cis conformation of a phosphorylated serine/threonine-proline motif of an amyloid precursor protein. The present invention also relates to treating and/or preventing in a subject a degenerative neurological disease characterized by amyloidogenic processing of amyloid precursor protein and/or overproduction of amyloid beta peptide. This method involves administering an agent that accelerates cis/trans isomerization of amyloid precursor protein at a phosphorylated serine/threonine-proline motif and/or inhibits production of amyloid β peptides. Methods of screening for therapeutic agents effective in treating and/or preventing such diseases, methods of screening for biological molecules involved in the amyloidogenic pathway, and compounds that mimic the cis conformation of a phosphorylated serine/threonine-proline motif of an amyloid precursor protein are also disclosed.
Abstract:
A novel class of NIMA interacting proteins (PIN), exemplified by Pin1, is provided. Pin1 induces a G2 arrest and delays NIMA-induced mitosis when overexpressed, and triggers mitotic arrest and DNA fragmentation when depleted. Methods of identifying other Pin proteins and Pin-interacting proteins and identifying compositions which affect Pin activity or expression are also provided.
Abstract:
A battery ejection mechanism for ejecting a battery housing removably attached to an electrical device housing. The mechanism includes at least two ejection members, each having a button and an arm. The arms are adapted to transfer a force applied on the buttons to the electrical device housing to provide a pushing force for ejection of the battery pack from the electrical device housing. Force on the buttons also causes associated latches on the battery pack to move to their release position.
Abstract:
A pneumatic tire comprising a plurality of wishbone shaped patterns, each comprising a first substantially inclined circumferential groove and a second substantially inclined circumferential groove; and a plurality of curved, substantially lateral grooves, wherein each first substantially inclined circumferential groove and each second substantially inclined circumferential groove is intersected by at least one substantially lateral groove, and each of the inclined circumferential and lateral grooves is perpendicular with the turning axis of the tire.
Abstract:
The invention relates to methods and compositions of WW-domains as phosphoserine and phosphothreonine binding modules. The WW-domain containing polypeptides of the invention can be used, for example, to regulate cell growth; to treat neurodegenerative diseases; to screen for substances that modulated interactions between WW-domain containing polypeptides and phosphorylated ligands; as drug targeting vehicles; to direct protein degradation; and in the treatment of certain diseases or conditions characterized by aberrant WW-domain containing polypeptides or their ligands.
Abstract:
The instant invention pertains to the discovery of two novel regulatory mechanisms of NF-kB. The instant invention demonstrates that NF-kB is regulated by Pin1-catalyzed prolyl isomerization and ubiquitin-mediated proteolysis of p65. Accordingly, the instant invention provides methods for regulating NF-kB, and diseases and disorders associated with NF-kB. Further, the invention provides compositions capable of modulating the activity or expression of NF-kB, Pin1, and/or the proteolysis of p65.
Abstract:
An engaging and ejecting device for expansion module/cell of portable computer, including a control member and a switch member pivotally disposed on one side of a housing of the portable computer. The control member and the switch member drivingly cooperate with each other. One side of the expansion module is disposed with a block body. After the module is inserted into the portable computer housing, the control member, switch member and control block drivingly cooperate with each other to engage the module inside the computer housing. When the switch member is pushed outward, the module is ejected out of the computer housing.
Abstract:
Providing malware-free web content to a user is disclosed. The web content is any type of web content that may potentially be infected by any type of malware. Upon receiving a request for a piece of web content from the user, the requested piece of web content is obtained from the appropriate source, and a dynamic template for the piece of web content is retrieved. The dynamic template indicates whether the requested piece of web content includes any malware and what actions are to be performed if any malware is included in the piece of web content. The requested piece of web content is cleaned up by performing the actions indicated in the dynamic template. Thereafter, the piece of web content is provided to the user. The dynamic template is updated from time to time based on the currently available information regarding the piece of web content.
Abstract:
A method for generating a behavioral model for a targeted advertisement category (TAC), including: obtaining click stream data including ad-clicks and events preceding the ad-clicks and performed on web pages; assigning features having categories and keywords associated with the web pages to the events; identifying an ad-click of the ad-clicks and a subset of the events preceding the ad-click that result in the ad-click, where the subset of the events is associated with at least one feature; generating an aggregated event sequence by aggregating the ad-click and the subset of the events; selecting, in response to the at least one feature being associated with the TAC, a training data set including at least the aggregated event sequence; generating the behavioral model for the TAC by applying a learning algorithm to a portion of the training data set; and evaluating performance of built models and select model based on performance result.
