The present invention pertains to an in vitro method for detecting intestinal barrier failure in an avian population, the method comprising the following steps: a) collecting a pooled fecal sample deriving from an avian population and b) determining the amount of at least one protein marker contained in said sample; wherein the at least one protein marker comprises or consists of an acute phase protein or a functional fragment thereof, and wherein an increased amount of said at least one protein marker contained in said sample versus a reference sample indicates intestinal barrier failure.

The invention encompasses methods and test strips for detecting the presence of cerebrospinal fluid (CSF) in a biological sample comprising removing sialo-transferrin and selectively detecting or measuring asialo-transferrin in the biological sample.

It is an object of the present invention to provide a method for determining the medicinal effect or sensitivity of an anti-transferrin receptor antibody. According to the present invention, provided is a method for determining the medicinal effect or sensitivity of an anti-human transferrin receptor antibody having an action to inhibit the binding between human transferrin and a human transferrin receptor, wherein the method uses an intracellular iron content as an indicator.

The present invention is the protein of lactoferrin, or an encoding nucleic acid of same, for use in the diagnosis or prognosis of Alzheimer's disease (AD). The invention is a method of diagnosis or prognosis of AD in a subject, comprising assessing the level of lactoferrin in the saliva or in a saliva sample of said subject and determining whether said level is above or below a value of 7.43 g/ml, wherein a value below 7.43 g/ml is indicative of AD or of the prognosis of AD. Another aspect is the protein of lactoferrin, or an encoding nucleic acid of same, for use in the diagnosis of Parkinson's disease (PD) in a saliva sample of a subject.

The present invention provides methods and systems to accurately detect and measure levels of endogenous antibodies, for examples endogenous IgA, to particular antigens in a biological sample from a companion animal, which is useful to diagnose inflammatory conditions, including bowel disease (IBD), gastrointestinal infections, and food sensitivities in companion animals, e.g., dogs or cats, and to distinguish among such gastrointestinal disorders. Such methods and systems identify whether a sample from the patient is associated with an inflammatory condition, infection, and/or food sensitivity condition, by using non-invasive means, thus conveniently providing information useful for guiding treatment decisions.

The present invention relates to the field of myocardial injury. More specifically, the present invention provides methods and compositions useful in the diagnosis, prognosis and/or assessment of myocardial injury. In a specific embodiment, a method comprises the steps of (a) diagnosing a subject as having myocardial injury based on the statistically significant over expression of one or more markers described herein compared to a baseline value, wherein the markers are measured in a biological sample obtained from the subject; and (b) treating the subject with one or more of an anti-thrombolysis agent, coronary bypass surgery or angioplasty.

Provided are methods for protein analysis in which proteins to be analyzed are displayed on a population of discrete and dispersible structures, such as beads or other particles, for subsequent affinity reactions and analysis/detection. The proteins to be analyzed may be provided as denatured protein samples in the presence of a denaturing agent.

We identified >40 proteins that elicited at least a 2-fold increase in antibody response post-pancreatic-cancer vaccination, from each of three patients' sera. The antibody responses detected against these proteins in patients with >3 years disease-free survival indicates the anti-tumor potential of targeting these proteins. We found that tissue expression of proteins PSMC5, TFRC and PPP1R12A increases during tumor development from normal to pre-malignant to pancreatic tumor. In addition, these proteins were shown to be pancreatic cancer-associated antigens that are recognized by post-vaccination antibodies in the sera of patients that received the vaccine and have demonstrated a favorable disease free survival.
