摘要:
Bacteria that are auxotrophic for at least two amino acids found in at least one tumor are effective anti tumor treatments, labeling agents, and vaccines against infection. Improved antitumor effects can also be provided such strains by passage through an appropriate tumor model.

An object recognition system performs a number of rounds of dimensionality reduction and consistency learning on visual content items such as videos and still images, resulting in a set of feature vectors that accurately predict the presence of a visual object represented by a given object name within an visual content item. The feature vectors are stored in association with the object name which they represent and with an indication of the number of rounds of dimensionality reduction and consistency learning that produced them. The feature vectors and the indication can be used for various purposes, such as quickly determining a visual content item containing a visual representation of a given object name.

The invention encompasses radiopharmaceutical compounds that can be used in imaging cell death associated with either apoptosis or necrosis. Phosphatidylethanolamine (PtdE) is externalized to the surface of apoptotic cells, and also becomes accessible in necrotic cells due to compromised plasma membrane integrity. Duramycin, a 19 amino acid polypeptide, binds PtdE at a 1:1 ratio with high affinity and exclusive specificity. Novel Duramycin-based radiopharmaceuticals and non-radioactively labeled compounds are disclosed herein. Such compounds facilitate detection of cell apoptosis and/or necrosis by binding to PtdE. The location of the bound compound can then be pinpointed using standard imaging techniques.

A system and method are set forth for remotely controlling a presentation from a portable electronic device so as to freeze a slide on a remote projector to permit searching for a desired slide on the portable electronic device and then continuing the presentation when searching is complete. In one embodiment, a switch is provided in a communication layer of a presentation application such that when the switch is turned off, communication is suspended between the portable electronic device and the projector, thereby permitting browsing on the portable electronic device without interrupting the presentation. When the switch is turned on the current slide information is transmitted from the portable electronic device to the projector.

A video demographics analysis system selects a training set of videos to use to correlate viewer demographics and video content data. The video demographics analysis system extracts demographic data from viewer profiles related to videos in the training set and creates a set of demographic distributions, and also extracts video data from videos in the training set. The video demographics analysis system correlates the viewer demographics with the video data of videos viewed by that viewer. Using the prediction model produced by the machine learning process, a new video about which there is no a priori knowledge can be associated with a predicted demographic distribution specifying probabilities of the video appealing to different types of people within a given demographic category, such as people of different ages within an age demographic category.

Polymers are described that are prepared from di and mono-functional silicone and silane monomers of Formula 1 in which Y represents a direct bond or a oxy group; R1 represents an optionally substituted organo group with at least one double bond which optionally may be an activated unsaturated moiety such as a (meth)acrylate group: for example 1-n-propoxy(acrylate) or ethenyl; and R2 and R3 each separately, and independently within each optional repeat unit, represent an optionally substituted hydrocarbo, hydrocarbo(oxy), hydrosilico and/or hydrosilico(oxy) groups; or example, methyl; or trimethylsiloxy; R4 independently represents an optionally substituted organo group with at least one double bond (such as R1 above) an optionally substituted hydrocarbo, and/or hydrosilico group for example trimethylsilyl or ethenyl; and n is from about 0 to about 2000; preferably from about 1 to about 100, for example n is 1. Such polymer precursors can be used to prepare flow modifying agents, defoamers and/or pressure sensitive adhesives.
摘要:
A multi-modal data acquisition system for detecting target material on a biological reaction surface, the system comprising a radiation source for generating an incoming beam that impinges on the biological reaction surface at an oblique incidence angle and produces a reflected beam, an interferometric detector for detecting an interferometric signal from the illuminated surface, the reflected beam being directed to the interferometric detector, a fluorescence detector for detecting a fluorescence signal from the illuminated surface; the fluorescence detector being positioned to substantially minimize the incidence of the reflected beam; and a processing system for receiving the interferometric and fluorescence signals and determining the presence or absence of target material on the biological reaction surface. A reaction surface conditioned for the simultaneous collection of fluorescence, interferometric and other signals. A multi-modal data acquisition system for collecting and processing additional modes, including multiple interferometric, fluorescence and scattering channels.

The invention relates generally to methods of influencing central nervous system cells to produce progeny useful in the treatment of CNS disorders. More specifically, the invention includes methods of exposing a patient suffering from such a disorder to a reagent that modulates the proliferation, migration, differentiation and survival of central nervous system cells. These methods are useful for reducing at least one symptom of the disorder.
摘要:
A system and method are set forth for remotely controlling a presentation in a loop mode to allow the presentation to continue in the absence of a communication channel between the portable electronic device and remote presentation device. In particular, the portable electronic device can issue a command to the remote presentation device to present the presentation in loop mode so that a user of the portable electronic device can leave the vicinity of the remote presentation device (e.g. out of communication range) while the presentation plays in loop mode.
