Provided herein are devices and methods for monitoring biofluids related to ovulation. Such devices include the use of electrochemical aptamer-based (EAB) sensors.

Provided is a model for evaluating the degree of liver fibrosis constructed based on bile acids. A plurality of bile acids are simultaneously detected by a liquid chromatography-tandem mass spectrometer to further improve the accuracy in combination with other liver indicators; moreover, a multiple regression analysis method is applied to establish a grading diagnosis model for the degree of liver fibrosis caused by a chronic liver disease, which can significantly improve the sensitivity and specificity of the existing non-invasive diagnosis of liver fibrosis. When the model is used to evaluate the degree of liver fibrosis of a patient, the highest AUC is up to 0.9278; the sensitivity is up to 86.79%; and the specificity is up to 89.01%. The detection results are completely consistent with the pathological results of clinical liver biopsy. Therefore, patients need not receive a liver biopsy.

The present invention relates to compounds which are suitable to be used in mass spectrometry as well as methods of mass spectrometric determination of analyte molecules using said compounds.

The present invention provides systems, devices, and methods for point-of-care and/or distributed testing services. The methods and devices of the invention are directed toward automatic detection of analytes in a bodily fluid. The components of the device can be modified to allow for more flexible and robust use with the disclosed methods for a variety of medical, laboratory, and other applications. The systems, devices, and methods of the present invention can allow for effective use of samples by improved sample preparation and analysis.

The present disclosure relates to a method for diagnosing mood disorder such as mania, depression and mania mixed using a circadian rhythm. According to the diagnostic method of the present disclosure, the condition of mood disorder can be diagnosed objectively and clearly based on the advance or delay of the circadian rhythm. That is to say, hypomania, mania, depression, mixed mania, etc. may be determined quickly and adequately so that appropriate therapeutic intervention can be made. In addition, according to the diagnostic method of the present disclosure, schizophrenia which is frequently confused with severe depression or bipolar disorder can be distinguished clearly. In addition, the selection of a therapeutic drug can be benefited greatly through this.

The present disclosure provides a compound having Formula (I): or a pharmaceutically acceptable salt of hydrate thereof, wherein R.sup.1, A, m, and n are as described herein, for use in conducting immunodiagnostic assays for accurately measuring concentrations of circulating vitamin D, as well as for thyroxine and related analytes, estrogen and related analytes, and testosterone and related analytes.

The invention relates to a kit and methods for quantitative detection of steroids in a sample. The kit comprises quantitative charge tags and an oxidizing agent.

The present invention provides novel antigens of an allergy to egg, methods and kits for diagnosing an allergy to egg, pharmaceutical compositions comprising such an antigen, eggs or processed products of egg in which such an antigen is eliminated or reduced, birds that deliver such eggs or are born from such eggs, a method for producing processed products of egg in which such an antigen is eliminated or reduced, and a tester for determining the presence or absence of an egg antigen in an object of interest. The present invention also relates to polypeptides comprising an epitope of an antigen, kits, compositions and methods for diagnosing an allergy, comprising such a polypeptide, pharmaceutical compositions comprising such a polypeptide, and raw materials or processed products in which an antigen comprising such a polypeptide is eliminated or reduced. The present invention further relates to a tester for determining the presence or absence of an antigen in an object of interest.

Methods and formulations of reducing one or more symptoms of gastroesophageal reflux disease (GERD) in a human patient with symptomatic GERD not completely responsive to proton pump inhibitors (PPIs). The patient is administered a therapeutically effective amount of an enteric coated gastro-retentive oral dosage form in the form of a tablet of a bile acid sequestrant dispersed in a polymeric matrix consisting essentially of poly(alkylene)oxide and one or more filler or compressing agent such that the patient experiences a clinically meaningful reduction in one or more symptoms of GERD.

Isolated polypeptides with steroid binding activity and methods for their use as therapeutics and detection agents are disclosed herein.
