Methods and kits for sampling mucous from within a sinus to determine if a single sample includes one or more bacterial types indicating a bacterial infection, such as bacterial sinusitis, and one or more viruses indicating a viral infection, such as influenza.

The invention provides for a proteomic approach for identification of specific bacterial protein profiles that may be used in the development of methods for the diagnosis of bacterial chronic sinusitis. The invention provides for methods for determining the presence of pathogenic bacteria in the upper respiratory tract of a subject using protein profiles of the pathogenic bacteria. The invention also provides for methods of diagnosing a bacterial infection of the upper respiratory tract of a subject using protein profiles of a pathogenic bacteria. In addition, the invention provides for devices, immunoassays and kits for identifying pathogenic bacteria in the upper respiratory tract.

The methods and apparatus of the present invention allow the evaluation of inflammation of the esophagus. 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.

Provided herein is technology for esophageal disorder screening and particularly, but not exclusively, to methods, compositions, and related uses for detecting the presence of esophageal disorders (e.g., Barrett's esophagus, Barrett's esophageal dysplasia, etc.). In addition, the technology provides methods, compositions and related uses for distinguishing between Barrett's esophagus and Barrett's esophageal dysplasia, and between Barrett's esophageal low-grade dysplasia, Barrett's esophageal high-grade dysplasia, and esophageal adenocarcinoma within samples obtained through endoscopic brushing or nonendoscopic whole esophageal brushing or swabbing using a tethered device (e.g. such as a capsule sponge, balloon, or other device).

Described are methods and compositions for increasing islet-1 (Isl1) activity (e.g., biological activity) and or expression (e.g., transcription and/or translation) in a biological cell and or in a subject.

Methods and kits for sampling mucous from within a sinus to determine if a single sample includes one or more bacterial types indicating bacterial sinusitis.

Recurrent tonsillitis disease (RT) is a common indication for pediatric tonsillectomy, the most frequent childhood surgery. It is unknown why some children develop RT. The present disclosure demonstrates that RT tonsils exhibit significantly smaller germinal centers than non-RT tonsils, concomitant with a bias against Group A Streptococcus (GAS)-specific germinal center follicular helper CD4.sup.+ T cells (GC Tfh), and significantly reduced antibodies to the GAS virulence factor SpeA. The present disclosure also shows a significant immunogenetic component to this disease, with the identification of at risk and protective HLA alleles for RT. Finally, the present disclosure identifies a new cell type, granzyme B+GC Tfh cells, which are activated by SpeA, are significantly more abundant in RT GC Tfh cells, and have the capacity to kill B cells, thus, providing a window into the immunology and genetics of a classic childhood disease and identifies a new type of pathogenic T cell.

The present invention, relates to the use of TFF3 in the diagnosis and detection of Barrett's Oesophagus using non-invasive, non-endoscopic methods.

The present disclosure relates to a kit and an information providing method capable of predicting or diagnosing a cause-specific therapeutic effect of sensorineural hearing loss. The kit and the method according to one aspect of the present invention can diagnose a cause-specific therapeutic effect of sensorineural hearing loss at an early stage and allow selection of the most appropriate treatment method.

The invention is directed to a method of detecting a biological substance in the nasal secretion and diagnosing a disease following the detection of the biological substance wherein the biological substance is not related to a respiratory disease. The invention also provides treatment of the diseases following the detection of the biological substance and/or diagnosis of the disease. In some embodiments, the diseases are cancer, hepatitis, smell loss, taste loss, diabetes, and leprosy. The invention also provides a kit for diagnosing a disease.

The present invention includes methods of analyzing samples from the nose for the detection of biological substances. In particular, nasal secretion or nasal mucus is collected and analyzed for biological substances. The results of this analysis are then suitable for use in diagnosis, prognosis, and determination of suitability of therapeutic interventions.
