The present invention is directed to a method for identifying an individual who is at risk for developing metastatic liver disease that involves measuring, in a sample isolated from the individual, exosomal levels of one or more markers of metastatic liver disease. Kits for carrying out this method are also disclosed. The present invention also relates to a method of preventing metastatic liver disease in an individual who are at risk for developing the disease that involves administering one or more inhibitors of liver pre-metastatic niche formation.

The invention provides a breath test for assessing a metabolic phenotypeand/or assessing a disease state.

The present invention relates to a method of directly detecting, using a mass-spectrometry method, whether a microorganism contained in a sample is resistant to antibiotics, and a kit for detection used therewith. More particularly, the present invention relates to a method and kit for directly detecting an antibiotic hydrolase secreted by a microorganism resistant to antibiotics, thereby directly determining whether the microorganism is resistant to antibiotics. According to the present invention, it is possible to very simply and immediately confirm whether a specific strain is resistant to antibiotics in the field. In particular, a complicated pretreatment process such as proteolysis is not performed, and a complicated identification process of calibrating and then combining the obtained results is not performed. Accordingly, it is possible to realize a method of easily confirming whether antibiotic resistance occurs in just a dozen minutes, compared to a conventional technology in which it takes several days to confirm whether antibiotic resistance occurs, and a simple diagnostic kit used therewith.

Disclosed are compounds having formula (1): ##STR00001##
or a pharmaceutically acceptable salt, ester, amide, solvate, or stereoisomer thereof, wherein L, Y.sup.1, Y.sup.2, Y.sup.3, Y.sup.4, Y.sup.5, Z.sup.1, Z.sup.2, Z.sup.3, Z.sup.4, Z.sup.5, Z.sup.6 are each as defined in the specification; compositions thereof; uses thereof; and methods of use thereof.

Provided herein are analytical methods utilizing a self-limiting catalytic reaction, and compositions and kits useful therefore. In one aspect the method is used to quantify Pd, and in another, the method is a horseradish peroxidase assay.

An enzymatic electrochemical sensor for the detection of blood propofol is provided.

Disclosed are methods and compositions which may be used in human cytochrome P450 (CYP450) enzyme phenotyping. The methods and compositions typically utilize substrate for CYP3A5 comprising eplerenone which may be administered orally to a subject. Subsequently, metabolites of eplereone may be detected in the subject's saliva as well as any non- metabolized eplerenone to calculate a metabolic ratio for CYP3A5 enzyme in order to generate a phenytopic CYP3A5 enzyme profile for the subject.

Light-generating fusion proteins having a ligand binding site and a light-generating polypeptide moiety and their use as diagnostics, in drug screening and discovery, and as therapeutics, are disclosed. The light-generating fusion protein has a feature where the bioluminescence of the polypeptide moiety changes upon binding of a ligand at the ligand binding site. The ligand may be, for example, an enzyme present in an environment only under certain conditions, e.g., ubiquitin ligase in a hypoxic state, such that the light-generating fusion protein is “turned on” only under such conditions.

This document provides methods and materials involved in identifying and/or treating mammals having a treatment-resistant prostate cancer (e.g., an enzalutamide-resistant, castration-resistant prostate cancer). For example, methods and materials for identifying a mammal (e.g., a human) having treatment-resistant prostate cancer (e.g., an enzalutamide-resistant, castration-resistant prostate cancer) as having an elevated level of one or more polypeptides (e.g., one or more of a CXXC5, a CXXC4, a TET2, an ID1, an ID3, and/or a PFN2 polypeptide) in treatment-resistant prostate tissue are provided. Methods and materials for administering one or more targeted therapies with or without one or more chemotherapeutic agents to a mammal having treatment-resistant prostate cancer identified as having an elevated level of one or more polypeptides (e.g., one or more of a CXXC5, a CXXC4, a TET2, an ID1, an ID3, and/or a PFN2 polypeptide) in treatment-resistant prostate tissue also are provided.

A method of dosing LSD in treating patients, by assessing genetic characteristics in the patient before LSD use, administering LSD to the patient based on the patient genetics, and producing maximum positive subjective acute effects in the subject and/or reducing anxiety and negative effects. A method of determining a preferred dose of LSD, by determining metabolic and genetic markers in a patient (such as by assessing CYP2D6 activity and/or assessing 5HTR1A rs6295 and 5HTR2A rs6313 genotypes in a patient), adjusting a dose of LSD based on the metabolic activity and genetic profile, administering the dose of LSD to the patient, and producing maximum positive subjective acute effects in the subject and/or reducing anxiety and negative effects. A method of determining a dose of LSD based on an assessment of the presence of CYP2D6 inhibitors.
