A composition for treating type 1 diabetes mellitus autoimmunity can include a therapeutically effective amount of two or more overlapping fragments of preproinsulin and a pharmaceutically acceptable carrier, wherein at least of the polypeptide fragments is antigenic.

A method for determining past exposure to chemical agents or heavy metals may include coating a capture material with a capture reagent. The capture reagent may be selected based on an ability of the capture reagent to bind with a target antibody, and the target antibody may be an indicator associated with a particular chemical agent or heavy metal. The method may further include interrogating a clinical sample associated with an individual by forming a mixture of the capture material and the clinical sample, and determining an exposure status of the individual to the particular chemical agent or heavy metal based on whether the capture material demonstrates capture of the indicator.

There are no FDA-approved disease-modifying therapies for GSDs like GSD Ia and GSD Ib. Disclosed herein are compositions for and methods of detecting GSD biomarkers as well as methods of diagnosing GSD, methods of determining the efficacy of a GSD treatment, methods of monitoring metabolic control status, and methods of determining the efficacy of regulating dietary intake of carbohydrates using the disclosed biomarkers.

This invention discloses diagnosis of risk of chemotherapy-induced cardiotoxicity by measurement of increased expression of soluble epoxide hydrolase in vitro and in vivo in cells, tissues or animals including measurement of increased levels of soluble epoxide hydrolase metabolites, e.g., 14,15-DHET and 11,12-DHET, in biological fluids. This invention also includes diagnosis of risk of chemotherapy-induced cardiotoxicity by measuring increased levels of oxidative stress in cells, tissues or animals including measurement of increased levels of oxidative stress biomarkers, e.g., 8-isoprostane, in biological fluids. Fatty acid and protein biomarkers to diagnose the risk of chemotherapy-induced cardiotoxicity are detected using various detection methods including mass spectrometry and immunoassay such as ELISA, Western blot analysis or label-free microwell and nanowell technologies. This invention discloses targeted medical intervention for a subject who is at risk or with chemotherapy-induced cardiotoxicity by treating with soluble epoxide hydrolase inhibitor(s) with or without antioxidants to prevent or ameliorate the chemotherapy-induced cardiotoxicity.

Disclosed herein are biosensors including transcription, translation, and coupled transcription/translation systems. The biosensors may be made from cell lysates, purified enzymes, or a combination thereof. The biosensors may include an inhibitor, and may include a reporter. The biosensor may be supplied in a kit for testing for a disease or condition. Methods of using the biosensor are also disclosed.

An object of the present invention is to provide a convenient sampling method and kit for histamine measurement. The present invention provides a method and a kit which involve non-invasively sampling a specimen, and detecting histamine from the obtained sample.

Methods and devices for rapid assessment of the severity of injury not due to a natural disease based upon measurement of neutrophil gelatinase-associated lipocalin (NGAL) are provided.

Described are glutathione adducts of fatty aldehydes (FALD-GSH) and methods useful in the detection of FALD-GSH in the identification of pathologies associated with leukocyte-mediated disease conditions, including eosinophil and neutrophil activation. Thus, the present disclosure provides methods of diagnosing a subject as having or being at risk of developing a leukocyte-mediated disease (LMD) comprising (a) detecting the level of glutathione adducts of 2-halofatty aldehydes (FALD-GSH) in a sample; (b) comparing the amount of FALD-GSH with a control or standard reflective of diseased and/or healthy levels of FALD-GSH; and (c) diagnosing the subject as having or being at risk of developing LMD if the level of FALD-GSH in the sample is higher than the control or standard.
