摘要:
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.

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.
摘要:
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.
摘要:
Methods for the use of Pin1 as a marker of abnormal cell growth are disclosed. In one embodiment, the method includes detecting a level of Pin1 to stage an abnormal cell growth, such as breast or prostate cancer. In another embodiment, the method includes evaluating the efficacy of a treatment of an abnormal cell growth, such as cancer, by monitoring the levels of Pin1. In another embodiment, the method includes evaluating the extent of metastasis of abnormal cell growth, such as cancer. The levels of Pin1 can be protein levels or nucleic acid levels.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.
