Tongs for manipulating shish-kebob on a barbeque grill, the tongs having two arms, the two arms being in parallel relationship at an insulated handle end which includes the pivot point at one end, the arms diverging at the opposing end of the handle end, to form two opposing spaced apart arms having kebob engaging ends, each end having an aperture there through, the apertures engaging the ends of the skewer, the tongs then being compressed so that the kebob engaging ends engage the outer food items on the skewer preventing their rotation so that the kebob may be either flipped for even cooking on the opposing side, or removed from the grill for consumption without endangering the fingers of the user.
摘要:
A method for producing a biomarker indicative of a repetitive head injury in a subject using a magnetic resonance imaging (MRI) system is provided. Two-dimensional spectroscopic data is acquired from a subject using an MRI system. From the two-dimensional spectroscopic data, a two-dimensional spectrum is produced. The two-dimensional spectrum contains spectral information indicated by a first spectral dimension and a second spectral dimension. Such a two-dimensional spectrum may include diagonal peaks and off-diagonal, or cross-peaks. In such an instance, each cross peak may indicate, for example, scalar coupling between the two protons it connects on the diagonal. However, depending on the type of method used, different types of coupling may also be present. Using the two-dimensional spectrum, a biomarker indicative of repetitive head injury in the subject is identified, and may be used to produce a report indicating a status or regression of a neurological dysfunction.

A method and system are disclosed for retrieving information through the use of a multi-stage interaction with a client to identify particular knowledge content associated with a knowledge map. The present invention is an application program running on a server accessed via the world-wide web or other data network using standard Internet protocols, a web browser and web server software. In addition to an automated portion, the present invention allows a human dialog designer to model the way the system elicits information, giving a human feel to the dialog and a better customer experience. In operation, users start a dialog by directing their web browser to a designated web page. This web page asks the user some initial questions that are then passed to a dialog engine. The dialog engine then applies its methods and algorithms to a knowledge map, using dialog control information\ and the user's responses to provide feedback to the user. The feedback may include follow-up questions, relevant documents, and instructions to the user (e.g., instructions to contact a human customer service representative). This dialog engine response is rendered as a web page and returned to the user's web browser. The user can then respond further to the follow-up questions he or she is presented, and the cycle repeats. The invention can be implemented so that it can interact with customers through a wide variety of communication channels including the Internet, wireless devices (e.g., telephone, pager, etc.), handheld devices such as a Personal Data Assistant (PDA), email, and via a telephone where the automated system is delivered using an interactive voice response (IVR) and/or speech-recognition system.
摘要:
The invention is based on the discovery of methods for purification of an acid active hyaluronidase found in human plasma (hpHAse), including both biochemical and immunoaffinity purification methods. The method of immunoaffinity purification of the invention is based on the discovery of a method for identifying antibodies that specifically bind native hpHAse (anti-native hpHAse antibodies), and anti-native hpHAse antibodies identified by this screening method. The invention also features an assay for sensitive detection of HAse activity using biotinylated hyaluronic acid (bHA). Purification and characterization of hpHAse lead to the inventors' additional discovery that hpHAse is encoded by the LuCa-1 gene, which gene is present in the human chromosome at 3p21.3, a region associated with tumor suppression. The invention additionally features methods of treating tumor-bearing patients by administration of hpHAse and/or transformation of cells with hpHAse-encoding DNA.

摘要:
A nickel catalytic system that makes it possible to obtain branched compounds from fatty substances by reacting simple olefins on polyunsaturated esters, which may or may not be conjugated, is described. The compounds that are obtained may be hydrogenated and used as lubricant bases or may be transformed according to known procedures into compounds of acid, alcohol, amine or amide type, used in varied applications.
