Abstract: The present invention is a system and method for significantly improving gas chromatography resolution using a dynamic and non-linear thermal gradient along the entire column length and is achieved by decreasing the velocity of analytes when approaching the back end of the capillary column in order to compensate for an increase in velocity of carrier gas as the carrier gas expands when approaching the back end, and wherein the thermal gradient is selected so that the analyte achieves a constant velocity through the capillary column.

Clamping shoes, disposed in opposition to one another within the receptacle, are elastically biased towards one another by at least one elastic member such that the clamping shoes engage opposing sides of a portion of the pot call residing within the receptacle. A flexible strap is coupled to the receptacle for securing the receptacle to a limb of a user.

Abstract: A MNase-Sequence Capture method, mTSS-seq, was developed herein to map genome-wide nucleosome distribution in cancer, for example primary human lung and colon adenocarcinoma tissue. Here, it was confirmed that nucleosome redistribution is an early, widespread event in lung adenocarcinoma (LAC) and colon adenocarcinoma (CRC). These altered nucleosome architectures are consistent between LAC and CRC patient samples indicating that they can serve as important early adenocarcinoma markers. As such, this consistency would be expected in other adenocarcinomas, as well as other carcinomas. It was demonstrated that the nucleosome alterations are driven by the underlying DNA sequence and potentiate transcription factor binding. DNA-directed nucleosome redistributions are widespread early in cancer progression, thus providing a methodology for early detection of cancer in grade one patients.

Abstract: A system for providing standard mixtures of volatile and semi-volatile organic compounds for simultaneous GC and MS calibration in a calibration vial, wherein calibration mixtures are prepared by diluting calibration analytes in granular PDMS such that most of the analytes are in the PDMS phase and the sample can then be taken from the analytes in the headspace vapor in the calibration vial, wherein a reliable calibration sample can be taken from the calibration vial because the analytes in the PDMS phase and the headspace vapor are in thermodynamic equilibrium, and wherein the method provides solvent-less sampling, long-time stability, ease of use, is quantifiable, and related to temperature.
