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.

The invention relates to complement inhibitors that inhibit both the classical and alternative complement pathways. In particular, the invention relates to complement inhibitors derived from the salivary glands of haematophagous arthropods that inhibit both the classical and alternative complement pathways. The invention also relates to the use of the complement inhibitors in the treatment and prevention of diseases.

Disclosed are specifically a marker polypeptide of a Bothrops atrox-like thrombin and a method thereof for detecting species source and content of a snake venom-like thrombin and an application, relating to the technical field of snake venom detection. An amino acid sequence of the marker polypeptide is EAYNGLPAK (SEQ ID NO:1), and the marker polypeptide may be used to detect the species source and content of the snake venom-like thrombin in a sample. The marker polypeptide of the present disclosure may play an important role in characterizing the species source and content of the snake venom-like thrombin in the sample, and fill in the blank of a quality standard of snake venom of the Bothrops atrox.

Reagents and methods to use said reagents for detection of markers of various aspects of Lyme disease have been identified in biological fluids thus permitting diagnosis or classification of Lyme disease subjects as well as indicating suitable methods of treatment.

A method and system for identifying and treating various medical conditions caused by toxins, pathogens, hormonal imbalances and other factors involving intravenous therapy.

The present invention provides an oxygenated fatty acyl glycerol for use in treating and/or preventing an inflammatory disease a subject.

A sensor uses a combination of biocompatible quantum dots and an organic fluorophore in a controlled ratio. The organic fluorophore exhibits fluorescence of a first color, and the biocompatible quantum dots are sized to exhibit fluorescence of a second color different from the first color. The biocompatible quantum dots are functionalized with an organic coating arranged to chemically interact with a substance to quench the fluorescence of the quantum dots. The sensor exhibits a ratio of fluorescence of the quantum dots and the organic fluorophore from which a presence of the substance can be detected.

Anaplasma Marginale surface protein OmpA and homologous genes from Anaplasmatacaea family members are used in compositions suitable for vaccines to treat or prevent infections caused by tick-born bacteria of the Anaplasmatacaea family. OmpA proteins or peptide fragments may be used in combination with other Anaplasmatacaea surface proteins to elicit an immune response. Furthermore, antibodies to OmpA proteins can be used in diagnostic methods to determine whether an individual has contracted an Anaplasmatacaea infection.
