  • Publication number: 20200318194
    Abstract: Methods and compositions disclosed herein generally relate to methods of improving clinical and economic outcomes to address adverse effects related to anesthesia, analgesics, opioids, and inadequate pain relief. Embodiments of the invention relate to the association between genes, specific polymorphisms of genes, and non-genetic factors with inadequate pain relief and anesthesia-, analgesic, and/or opioid-related adverse effects. Embodiments of the invention can be used to determine and manage patient risk factors for development of adverse perioperative effects and can allow for personalized anesthesia and pain management for improvement of pain control and reduction of anesthesia-, analgesic-, and opioid-related adverse outcomes. These methods and compositions apply to non-surgical pain management with opioids.

  • Publication number: 20200199544
    Abstract: Provided are a proline hydroxylase and uses thereof. The proline hydroxylase comprises (a) a protein having the amino acid sequence as shown in SEQ ID NO: 2; (b) a protein having an amino acid sequence of SEQ HD NO: 2 with a mutation of one or more amino acids and having a proline hydroxylase activity; or (c) a protein retaining the mutation of one or more amino acids as in (b), and having the proline hydroxylase activity and having at least 78% homology with the amino acid sequence of the protein in (b). Protein having the amino acid sequence as shown in SEQ HD NO: 2 and mutants obtained by genetically engineering have higher catalytic specificity or significantly increased catalytic activity when compared to proline hydroxylases in prior art.

  • Publication number: 20190003001
    Abstract: An oil-immersion quenching cooling precursor and an oil-immersion quenching cooling method includes an axle-type workpiece or a workpiece that has sections in an axle form. Several separation rings are arranged on the workpiece in the axial direction to separate the axle-type workpiece or the workpiece that has sections in an axle form into a plurality of sections before oil-immersion quenching cooling. In the method, there is a cutting procedure before a quenching cooling procedure. Several separation rings distributed in the axial direction are reserved outside a dimension required for the workpiece. sections before oil-immersion quenching cooling.

  • Publication number: 20140377757
    Abstract: Amplification primers, sequencing primers, kits for screening, and screening methods for identifying a SLC6A8 creatine transporter gene mutation are disclosed. The screening method includes treating a sample of DNA with polymerase chain reaction amplification primers for amplifying regions of the DNA having SLC6A8 to produce a first, second, and third amplification product, sequencing the first, second, and third amplification products with sequencing primer pairs to provide a DNA sequence of SLC6A8 in the sample, and comparing the DNA sequence of SLC6A8 with a reference DNA sequence of SLC6A8.

  • Publication number: 20090253878
    Abstract: A polyolefin polymer comprising one or more terminal polymerizable methacryloyl groups (i.e. tethered to the main body of the polymer) and a novel process for preparing same are herein disclosed. A hyperbranched polyethylene polymer and a process for preparing same are also disclosed. The polymer is prepared by a novel one-pot copolymerization reaction of an olefin, such as ethylene, and a heterobifunctional comonomer comprising a methacryloyl group, catalyzed by a late transition metal ?-diimine catalyst which is selectively non-reactive towards methacryloyl groups. The process allows for preparation of polymers with various chain topologies, including linear, branched, and hyperbranched topologies. The terminal methacryloyl groups within the polymer are reactive in further polymerization reactions. Thus, the polymer may be used in materials and applications which require cross-linking or further polymerization, for example, UV/thermal/radical curable crosslinkers for use in thermoset applications.
