摘要:
Mass spectrometry techniques for determining the status of sepsis in an individual are provided. A biomarker profile resolved from a biological sample, taken from the individual, using a mass spectrometry technique is compared to a reference biomarker profile. A single such comparison classifies the individual as belonging to or not belonging to a reference population. The individual's biomarker profile and the reference biomarker profile comprise a plurality of ions each having a mass-to-charge ratio of about 100 Daltons to about 1000 Daltons. The plurality of ions can be detected by electrospray ionization mass spectrometry in positive mode. The comparison uses a decision rule, such as a classification tree, that determines the status of sepsis in the individual without requiring knowledge of the identity of the biomarkers in the biomarker profile from the individual and without requiring knowledge of the identity of the biomarkers in the reference biomarker profile.

The present invention pertains to methods of quantifying the levels of at least one analyte in a sample or extract comprising adding a known quantity of at least one internal standard to the sample or extract. The present invention also relates to internal standards used in mass spectrometry, as well as compositions thereof. Internal standards for mass spectrometry according to the invention can be used, for example, to assist aligning mass spectra obtained from two different samples, each of which comprises the internal standard. In one aspect of the invention, the internal standard is a dendrimer. A labile internal standard may be used in conjunction with the dendrimer.

An Avocado Skinning and Pulping Device. The avocado pulper has two grip belts approximately oval in shape and further having a plurality of grip plates around the grip belts. The grip plates are knurled thereby facilitating a grasping of an avocado as it is conveyed into the grip belts and rides through to the rear opening. A pivotable and adjustable belt guide within an inner section of each grip belt is adapted to exert maximum squeezing pressure on the avocado at the approximate middle section of the grip belts at which point the grip belts are in approximate contact with one another. Pulp is thereby squeezed from the avocado. The grip belts separate at the approximate rear defining space for releasing the skin of the avocado. A de-seeder adjacent to the front end opening of the grip belts removes the seed from the avocado prior to its entry into the maximum squeezing section.

There is provided herein a system and method for automatic configuration of data routings for use with electronic data such as phone calls, faxes, etc. In an exemplary embodiment, when more than one carrier might potentially terminate the transmission, the carriers are ordered based on some screening criterion (e.g., transmission price). Data transmissions are then assigned to the carriers based on the sorting order, with the second place and lower carriers (e.g., the higher priced carriers) not being selected unless the first carrier cannot complete the transaction. The switch instructions necessary to implement this scheme may be generated automatically.

Embodiments related to detecting object information from image data collected by an image sensor are disclosed. In one example embodiment, the object information is detected by receiving a frame of image data from the image sensor and detecting a change in a threshold condition related to an object within the frame. The embodiment further comprises adjusting a setting that changes a power consumption of the image sensor in response to detecting the threshold condition.

A system, method and computer readable medium are disclosed that allow a set top box to receive control messages transmitted using multicasting. The set top box is programmed with either an address or a URL that it uses to obtain the control messages directly, or obtain other messages that carry the multicast address. In other implementations, a specialized offer message is transmitted to the set top box in response to a discover message. Embedded within the specialized offer message is the multicast address being used to multicast the control messages.
