Abstract: A method for determining a presence of a pancreatic tumor, assessing a development or risk of development of a pancreatic tumor, and/or assessing a progression of a pancreatic tumor, including determining a presence and/or content of a modification status of a DNA region with gene EBF2 or a fragment thereof in a sample to be tested.

Abstract: Compositions and methods for regenerating pancreatic islet viability and/or cell proliferation in vitro, ex vivo, and/or in vivo; and/or for regenerating glucose-stimulated insulin secretion; and/or for regenerating viability and/or cell proliferation of a transplanted pancreatic islets; and/or for preventing and/or inhibiting rejection of a transplanted islets; and/or for pancreatic islet transplantation; and/or for treating a symptom of a condition, disorder, or disease associated with abnormal insulin responsiveness to glucose are provided. In some embodiments, the compositions include a peptide and/or a pharmaceutically acceptable salt thereof, and/or a biologically active fragment, analog, or derivative thereof, wherein the peptide, the pharmaceutically acceptable salt thereof, and/or the biologically active fragment, analog, or derivative thereof has an amino acid sequence of any of SEQ ID NOs: 1-60, or any combination thereof.

Abstract: A gas injection system, a reactor system including the gas injection system, and methods of using the gas injection system and reactor system are disclosed. The gas injection system can be used in gas-phase reactor systems to independently monitor and control gas flow rates in a plurality of channels of a gas injection system coupled to a reaction chamber.

Abstract: A reactor system including a gas distribution assembly and method of using the reactor system are disclosed. The gas distribution assembly includes a gas distribution device, a gas expansion area, and a showerhead plate downstream of the gas distribution device and the expansion area.

Abstract: This invention provides an integrated chair frame motor transmission assembly for adjusting the position of a chair backrest bracket, including a bracket. A fixing part fixed to the chair frame is arranged at an upper end and a lower end of the bracket. A motor speed reducing module is fixed to the bracket, and one end of a screw rod is connected to the motor speed reducing module. The other end of the screw rod is connected to a fixing block, and the fixing block is fixed to the bracket. A sliding groove is formed in the bracket, and a sliding block is arranged corresponding to the sliding groove. The screw rod is matched with and connected to the sliding block and drives the sliding block to move back and forth along the sliding groove.

Abstract: A coating and a method to form the coating is proposed for a semiconductor film pre-clean and etch apparatus. The coating may be employed in environments where it is difficult to use a traditional coating or coating method. The coatings provide advantages including: an ability to effectively deliver hydrogen radicals and fluorine radicals to a wafer surface in one apparatus or individually in two apparatuses; a coverage of high aspect ratio features on critical components; an operability in high temperatures exceeding 150° C.; and a protection of a part with high aspect ratio features underneath the coating, thereby preventing metal and particles on a processed wafer.
