  • Publication number: 20230203589
    Abstract: The invention relates to systems and methods for determining personalized recommended daily intake, for example, the recommended daily allowance (RDA) for nutrients based on genetic information of the individual. In several embodiments, the systems and methods of the invention can be used to determine recommendations for specific nutrient supplements, foods, beverages, meals, menus, diets and recipes for an individual which are more accurately adapted to their needs based on their personal genetic risk scores.

  • Patent number: 10513676
    Abstract: Provided is a measurement method whereby the amount of unbound bilirubin (UB) can be exactly reflected whether a specimen contains a large amount of conjugated bilirubin or not. The measurement method for UB according to the present invention comprises decomposition step (i), decomposition stopping step (ii), contact step (iii) and detection step (iv). In decomposition step (i), a blood sample containing unconjugated bilirubin (iD-Bil) and conjugated bilirubin (D-Bil) is subjected to an oxidative decomposition reaction of UB in iD-Bil and D-Bil. In decomposition stopping step (ii), the oxidative decomposition reaction is stopped to give a decomposition product of the sample. In contact step (iii), the decomposition product of the sample is contacted with UnaG that is capable of specifically binding to iD-Bil. Separately, an unreacted sample, which is the blood sample not subjected to decomposition step (i), is contacted with UnaG too.

  • Patent number: 9957308
    Abstract: In order to provide a novel fluorescent protein and use thereof, the polypeptide according to the present invention has fluorescent properties in the presence of bilirubin and includes (1) the amino acid sequence of SEQ ID NO: 1, (2) an amino acid sequence having, for example, substitution of 1 to 21 amine acids in the amino acid sequence of SEQ ID NO: 1, (3) an amino acid sequence having 85% or more sequence identity to the amino acid sequence of SEQ ID NO: 1, or (4) the amino acid sequence encoded by a polynucleotide that hybridizes with a polynucleotide consisting of a sequence complementary to the polynucleotide encoding the polypeptide according to the amino acid sequence in (1) under a stringent condition.

  • Patent number: 8080531
    Abstract: ATR kinase is a key regulator of checkpoint responses to incompletely replicated and damaged DNA. Without this checkpoint, cells will enter mitosis prematurely, likely resulting in cell death. The invention provides methods and reagents to either block or activate the activation of the ATR kinase checkpoint, through, for example, either blocking or activating the expression of an ATR activator TopBP1. The invention also provides screening methods to identify additional ToBP1 inhibitors or activators that may be used to modulate the activity of the ATR checkpoint.

  • Patent number: 7807489
    Abstract: A light-emitting device with a protection layer for Zn inter-diffusion and a process to form the device are described. The device of the invention provides an active layer containing aluminum (Al) as a group III element, typically AlGaInAs, and protection layers containing silicon (Si) to prevent the inter-diffusion of zing (Zn) atoms contained in p-type layers surrounding the active layer. One of protection layers is put between the active layer and the p-type cladding layer, while, the other of protection layers is disposed between the active layer and the p-type burying layer.
