A method for measuring radiation intensity includes measuring the radiation intensity received by the protein in a radiation field based on degree of protein degradation in the radiation field, wherein the degree of degradation is a ratio of the molecular weight of the protein before and after irradiation. The measuring method is simple in operation, small in number of steps, small in error, and capable of measuring radiation doses of various radiation fields or even mixed radiation fields. Use of a biological dosimeter for measuring the radiation intensity by the method in a neutron capture therapy system can not only assess radiation contamination in the irradiation chamber, but also evaluate the neutron dose.

The present invention provides a method, wherein the method classifies a subject as suffering from dry eye, the method consisting of: a. obtaining demographic data, consisting of the age and gender of the subject; b. obtaining a tear sample from the patient, and determining the level of human serum albumin; c. from the determined level of human serum albumin, assigning a score for the determined amount of human serum albumin; and d. from the assigned score, calculating a cutoff probability score, according to the following equation: $\frac{\exp \left(-0.6491-1.1142*\mathrm{Albumin}\right)}{1+\exp \left(-0.6491-1.1142*\mathrm{Albumin}\right)}$
wherein the subject has dry eye, if the calculated cutoff probability score is from 50% to 60%.

This disclosure provides methods, systems, and compositions of matter for studying solvent accessibility and three-dimensional structure of biological molecules. A plasma can be used to generate marker radicals, which can interact with a biological molecule and mark the solvent-accessible portions of the biological molecule.

An in vitro method for diagnosing Alzheimer's disease (AD) includes determining the content of mercaptoalbumin (HMA) in a sample of cerebrospinal fluid (CSF), and comparing the content determined with the content of HMA in CSF in healthy subjects. If the HMA content is less than that of the healthy subjects, it is indicative of AD.

The present invention relates to a method for quantitative measurement of catechol estrogen bound protein in blood sample. By detecting adduction levels of binding sites of the catechol estrogen on the protein in blood sample, the catechol estrogen bound protein in the blood sample can be detected quantitatively and a limit of quantitation can be decreased.

The object of the present invention is a method of diagnosis of a chronic kidney disease (CKD) or glomerulopathy in a subject, comprising the following steps: (a) determination of the level of at least three or four or five protein markers selected from the group consisting of serum albumin (ALB), alpha-1-antitrypsin (serpinal), alpha-1-acid glycoprotein 1 (ORM1), serotransferrin (TF) and trefoil factor 1 (TFF), wherein said markers also comprise the non-full-length fragments thereof, in a urine sample from said subject and (b) assigning a probability of the subject having or being at a risk of chronic kidney disease or glomerulopathy or not having nor being at a risk thereof based on the results of the assay of step (a), wherein this involves estimating a probability of the subject having or being at a risk of chronic kidney disease or glomerulopathy or not having nor being at a risk thereof based on the level of each of the marker levels determined in (a)), the probability being estimated based on the levels of each of the markers as determined in subjects known to suffer from a glomerulopathy or a chronic kidney disease; and determining the probability of the subject, providing the urine sample tested in step (a), having or being at a risk of a glomerulopathy or a chronic kidney disease or not having nor being at a risk thereof as a product of the corresponding probabilities obtained from each marker. A further object of the present invention is a method of monitoring a response to treatment of a chronic kidney disease (CKD) or glomerulopathy in a subject, comprising the following steps: a) measurement of the level, at a first point in time, for three or four or five of the markers selected from a group consisting of serum albumin (ALB), alpha-1-antitrypsin (serpinal), alpha-1-acid glycoprotein 1 (ORM1), serotransferrin (TF) and trefoil factor 1 (TFF), wherein said markers also comprise the non-full-length fragments thereof, in a urine sample from a subject; b) repeating the assay of step (a) at a later point in time after a period wherein the subject was undergoing a treatment; c) assessing a response to said treatment by comparing the results of the assays of steps (a) and (b), wherein lower marker levels after treatment are indicative of a positive response to treatment. A further object of the present invention is a method of treatment of a chronic kidney disease (CKD) or glomerulopathy in a subject, comprising the following steps: (a) determination of the level of at least three or four or five protein markers selected from the group consisting of serum albumin (ALB), alpha-1-antitrypsin (serpinal), alpha-1-acid glycoprotein 1 (ORM1), serotransferr
