Provided is an antibody that recognizes and binds to carbonic anhydrase or antigen-binding fragment, a nucleic acid molecule coding for the antibody or antigen-binding fragment, a vector carrying the nucleic acid molecule, a host cell including the nucleic acid molecule or the vector, and use of the antibody or antigen-binding fragment thereof in the alleviation, prevention, treatment or diagnosis of solid cancers.

The present disclosure relates to a method for obtaining an antibody or antigen-binding fragment thereof that specifically binds to and against a tumor sample, comprising: administering autologous dendritic cells to a subject; taking immune cells and a tumor sample from the subject; constructing an antibody library of the immune cells; and screening the antibody library to obtain the antibody or a fragment thereof specifically binding to and against the tumor sample. The disclosure also relates to a method for engineering immune cells, an antibody or antigen-binding fragment thereof that specifically binds to and against a tumor sample and uses thereof.

A method for efficiently purifying and detecting 6-hydroxynobilonine in fresh stems of dendrobium huoshanense uses a gas chromatography-mass spectrometry (GC-MS) method to detect 6-hydroxynobilonine in dendrobium huoshanense is, i.e., a to-be-detected solution of 6-hydroxynobilonine is extracted from fresh stems of dendrobium huoshanense, the extraction method is as follows: freeze-drying, smashing and screening fresh stems of dendrobium huoshanense to obtain dendrobium dry powder, adding water for performing ultrasonic treatment, and then adding a composite enzyme for enzymolysis to obtain an enzymolysis solution; adding acidity alcohol into the enzymolysis solution, extracting for 1 min under an ultra-high pressure, and then taking filtrate; and concentrating the filtrate in vacuum, then purifying using a mixed-mode cation exchanger (MCX) extraction column, eluting with a methanol-acetonitrile solution, collecting eluent, blowing with nitrogen until no water, and then dissolving with methanol and filtering to obtain the to-be-detected solution.

The invention provides anti-CaENO1 antibodies and humanized antibodies as effective diagnostic agent or therapeutic treatment against infections caused by Candida spp. (preferably Candida. albicans, Candida tropicalis), fluconazole resistance Candida spp., Streptococcus, or Staphylococcus.

The present disclosure relates to compounds that are useful as near-infrared fluorescence probes, wherein the compounds include i) a ligand that binds to the active site of carbonic anhydrase, ii) a dye molecule, and iii) a linker molecule that comprises an amino acid, amide, ureido, or polyethylene glycol derivative thereof. The disclosure further describes methods and compositions for making and using the compounds, methods incorporating the compounds, and kits incorporating the compounds.

Provided herein are methods of diagnosing or monitoring the treatment of abnormal glycan accumulation or a disorder associated with abnormal glycan accumulation.

Provided herein are processes for detecting oligosaccharides in a biological sample. In specific instances, the biological sample is provided from an individual suffering from a disorder associated with abnormal glycosaminoglycan accumulation.

Novel complexes of peptides from human collagen type II and types of MHC class II associated with rheumatoid arthritis are provided. There is also provided novel therapies and methods for diagnosis of rheumatoid arthritis.

Methods for quantifying the amount of drug present in a prodrug composition are provided.

In some embodiment, the present invention is directed to a device for obtaining samples from a subject. In other embodiments, methods and devices of the present invention allow the evaluation of conditions of the gastrointestinal tract of a subject. Measurements may be utilized, for example, to diagnose a disease of the esophagus, to monitor inflammation of the esophagus, or to access the treatment of a disease of the esophagus. In one embodiment, the invention comprises a method for measuring esophageal inflammation comprising deploying a device into the esophagus of a subject, removing the device after a predetermined period of time, analyzing the device for a diagnostic indicator of esophageal inflammation and evaluating the diagnostic indicator to diagnose esophageal inflammation.
