摘要:
The present invention discloses uses of a HLA-B*1301 allele, comprising: 1) a use of a substance for detecting whether a person has the HLA-B*1301 allele in preparation of a product for evaluating a risk of adverse drug reactions in response to dapsone in the person; 2) a method for detecting or evaluating a risk of adverse drug reaction in response to dapsone in a person, comprising detecting whether the person has the HLA-B*1301 allele, wherein, a person with LA-B*1301 allele suffers a higher risk of adverse drug reaction upon being administered dapsone, as compared with a person without HLA-B*1301 allele, and a person with LA-B*1301 alleles at both chromosomes of a pair of homologous chromosomes suffers a higher risk of adverse drug reaction upon being administered dapsone, as compared with a person with HLA-B*1301 allele at only one of a pair of homologous chromosomes.

A method of calibrating a glucose sensor, which method comprises: (a) preparing a first glucose-containing calibration solution by combining water or an aqueous solution with alpha and beta glucose, the alpha and beta glucose being provided in solid form; (b) exposing a glucose sensor to said first glucose-containing calibration solution and determining the sensor output; (c) exposing the glucose sensor to one or more further calibration solutions having different glucose concentrations from each other and from said first glucose-containing calibration solution and determining the sensor output for the or each calibration solution; and (d) determining a calibration curve from the sensor output data collected in steps (b) and (c); wherein the first glucose-containing calibration solution of step (a),and if used the or each glucose-containing calibration solution of step (c), is prepared using 25 to 50 % alpha glucose and 50 to 75 % beta glucose, and wherein the first glucose-containing calibration solution of step (a), and if used the or each glucose-containing calibration solution of step (c), is prepared by combining water or an aqueous solution with freeze-dried glucose.
摘要:
This invention is a process for enzymatic synthesis of estolides through the reaction between stearic acid and methyl ricinoleate, using an immobilized lipase as the catalyst, in a solvent-free medium. This process prevents degradation of the product, reduces the formation of secondary products that generate color and odor in the lubricant, and allows recovery of the lipase and its subsequent reuse.

The present invention provides a pharmaceutical preparation for tumor chemotherapy and a method for producing the same, the pharmaceutical preparation for tumor chemotherapy comprises cell vesicles derived from apoptotic tumor cells and chemotherapeutic drugs as active ingredients wrapped within the cell vesicles. The chemotherapeutic drugs contained within the pharmaceutical preparation are chemotherapeutic drugs containing active ingredients for the treatment of the tumors from which the cell vesicles are provided. The present invention also provides a method for producing the pharmaceutical preparation for tumor chemotherapy. The technical solutions provided by the present invention can selectively release the chemotherapeutic drugs to the tumor sites and maintain lasting medicinal effect, increasing their killing effects against tumor cells and reducing the toxic side-effect of the chemotherapeutic drugs to normal cells.

A method of calibrating a reversible-binding sensor for detecting an analyte includes: (i) varying the temperature of a first calibration solution from a first temperature (T1) to a second temperature (T2) while the first calibration solution is in contact with a sensing region of the sensor; (ii) determining the sensor output for the first calibration solution as a function of temperature; (iii) varying the temperature of a second calibration solution from a third temperature (T3) to a fourth temperature (T4) while the second calibration solution is in contact with the sensing region, the second calibration solution having a concentration of analyte which is different from that of the first calibration solution; (iv) determining the sensor output for the second calibration solution as a function of temperature; and (v) using the determined sensor output from steps (ii) and (iv) to calibrate the sensor.

An Fe-Ni alloy pipe stock having a chemical composition comprising, by mass %, C ≤ 0.04%, Si ≤ 0.50%, Mn: 0.01 to 6.0%, P ≤ 0.03%, S ≤ 0.01%, Cr: 20 to 30%, Ni: 30 to 45%, Mo: 0 to 10%, W: 0 to 20%, with Mo(%) + 0.5W(%): more than 1.5% to not more than 10%, Cu: 0.01 to 1.5%, Al ≤ 0.01% and N: 0.0005 to 0.20%, and the balance substantially being Fe, with 1440 - 6000P - 100S - 2000C ≥ 1300, Ni + 10(Mo + 0.5W) + 100N ≤ 120, (Ni - 35) + 10(N - 0.1) - 2(Cr - 25) - 5(Mo + 0.5W - 3) + 8 ≥ 0, can be manufactured into a seamless pipe by use of a Mannesmann piercing and rolling mill because of its excellent inner surface properties. The resulting seamless pipe has excellent mechanical properties and moreover has excellent corrosion resistance in a sour gas environment, and thus, the Fe-Ni alloy pipe stock can be used as a pipe stock for oil country tubular goods and line pipes and further as a pipe stock for various structural members of nuclear power plants and chemical industrial plants.
摘要:
An imaging agent for cells which produces an intracellular imaging signal proportional to the amount of hCE-1 in the cells independently of the amount of hCE-2 and/or hCE-3 in the cells, said imaging agent being a covalent conjugate of (a) an imaging agent and (b) an alpha mono- or di-substituted amino acid ester, wherein (a) is directly linked to (b), or (a) is indirectly linked to (b) by a linker radical, and wherein said direct or indirect linkage is via the amino group of (b), and wherein the amino group is not directly linked to a carbonyl group, and wherein the said alpha mono- or di-substituted amino acid ester part is selectively hydrolysable to the corresponding carboxylic acid part by the intracellular carboxylesterase enzyme hCE-1 relative to the intracellular enzymes hCE-2 or hCE-3.
