Provided herein are peptide formulations comprising polymers as stabilizing agents. The peptide formulations can be more stable for prolonged periods of time at temperatures higher than room temperature when formulated with the polymers. The polymers used in the present invention can decrease the degradation of the constituent peptides of the peptide formulations.

A method for collecting information about the health status of a subject is proposed involving the quantitative detection, in serum, plasma or blood of the subject, of the concentration of THBS1, the proportion of free PSA (% fPSA), preferably including the concentration of at least one protein selected from the group consisting of CTSD, OLFM4, ICAM1.

[Problem] To provide a method for detecting high-risk prostate cancer, for the purpose of providing useful information, such as necessity of biopsy, to a test-positive patient in a PSA test. [Solution] The method for detecting high-risk prostate cancer according to the present invention comprises reacting a PSA contained in a sample composed of urine collected from a human body which is suspected to be suffering from prostate cancer with (1) a fucose α1.fwdarw.6 affinitive lectin which has a characteristic property that the lectin has affinity expressed by a binding constant of 1.0×10.sup.4 M.sup.−1 or more (at 25° C.) for an α1.fwdarw.6 fucose sugar chain No. 405. The fucose α1.fwdarw.6 affinitive lectin is preferably (2) a fucose α1.fwdarw.6 specific lectin which has a characteristic property that the lectin has a binding constant of 1.0×10.sup.4 M.sup.−1 or less (at 25° C.) for a sugar chain No. 003 that does not contain α1.fwdarw.6 fucose and a glycolipid-type sugar chain No. 909 that does not contain α1.fwdarw.6 fucose.

According to one embodiment, a detection device includes a sensor element and a probe molecule. The probe molecule is immobilized at the sensor element. The probe molecule associates with a receptor exposed at a surface of a detection target. The sensor element detects cleavage of the receptor having associated with the probe molecule.

The present invention relates to methods for treating or preventing a coronavirus infection with serine protease inhibitors targeted against the host protease, transmembrane serine protease 2 (TMPRSS2), and related compositions and methods.

Methods are provided for extracting one or more neutrophil serine proteases (NSPs), e.g., neutrophil elastase (NE), proteinase 3 (PR3), cathepsin G (CatG), neutrophil serine protease 4 (NSP4), or a combination thereof, from a sample comprising white blood cells (WBCs) obtained from a subject. The extraction methods feature the use of nonionic surfactants and two or more cycles of repeated lysis of WBCs and their residuals. Also provided are methods for treating dipeptidyl peptidase 1 (DPP1)-mediated conditions in a patient with compositions comprising certain N-(1-cyano-2-phenylethyl)-1,4-oxazepane-2-carboxamide compounds of formula (I), including pharmaceutically acceptable salts thereof,

that reversibly inhibit (DPP1) activity. The treatment methods provided herein use the concentration of active NSPs extracted from a patient's WBC sample as a biomarker to guide the selection of, or adjustment to, an effective dosage of the compounds of formula (I).

This invention relates to methods of diagnosing COVID-19 disease, preferably post-acute COVID-19 syndrome, in a subject using a fluorescent or microscopy detection method to detect persistent anomalous (amyloid) clotlets in the sample, wherein the presence of persistent anomalous (or amyloid) clotlets in the sample, particularly clotlets that are resistant to fibrinolysis, is indicative of either acute COVID-19 disease or post-acute COVID-19 syndrome in the subject. The invention also relates to diagnostic kits for diagnosing acute COVID-19 disease, in particular post-acute COVID-19 syndrome, in a subject based on the methods disclosed.

The present application relates to an effective dosage of an aqueous solution comprising an engineered AAT-Fc fusion dimeric protein for use in a method of treating or alleviating a symptom associated with aberrant serine protease activity in a subject in need thereof.

Use of caseinolytic protease P (ClpP) function and/or concentration as a biomarker for predicting the response of a neoplastic disease, preferably cancer or another disease where enhancing ClpP activity may provide a therapeutic benefit, to a compound of Formula I. In other aspects it relates to methods and kits, as well as methods of treatment involving the use of the biomarker.

Disclosed herein are evacuated blood collection tubes comprising protease inhibitor cocktails in liquid form and uses thereof for assessing features associated with the contact system in a subject, including the endogenous level of contact system activation, the endogenous level of a drug that targets a component of contact system during treatment, and/or the immunogenicity of such a drug.
