Resumen de: US20260347488A1

The invention belongs to the field of biomedicine, and particularly relates to a humanized anti-human CD132 monoclonal antibody and a use thereof. According to the invention, based on monoclonal chimeric antibodies 2D4 and 5H10 previously obtained in the laboratory, humanized transformation is performed on a target antibody, so as to screen and obtain high-affinity humanized monoclonal antibodies h2D4H4K12 and/or h5H10H6K4 targeting human CD132, so that, without attenuating antibody activities, immunogenicities of parental chimeric antibodies are reduced, thereby reducing the risk of potential immune responses to the antibodies in patients receiving the antibodies. The antibodies have promising application prospects in therapeutic drugs for prevention, neutralization or treatment of autoimmune diseases related to IL-4, IL-7, IL-9, IL-15 and/or IL-21 cytokines (such as systemic lupus erythematosus, rheumatoid arthritis, vitiligo, psoriasis, alopecia areata, inflammatory bowel disease, systemic sclerosis, graft-versus-host disease and aplastic anemia).

Resumen de: US20260351393A1

A non-contact bowel movement detection system for a dependent individual includes a patient unit, a cloud-based processing platform, and a mobile application. The patient unit is positioned in an occupied room and includes a housing with air intake apertures on a side surface and air exhaust apertures on a top surface. The housing contains a microcontroller with wireless communication, gas sensors including hydrogen, hydrogen sulfide, and volatile organic compounds, and a temperature and humidity sensor. An internal fan draws ambient air through the intake apertures, across the sensors, and out through the exhaust apertures to enhance detection. The microcontroller periodically collects sensor data and transmits it to the cloud platform. The cloud platform applies a machine-learning model to determine a bowel movement probability and generates an alert when a threshold is met. The mobile application receives and forwards the alert to a caregiver device.

Resumen de: US20260309591A1

A system and method for monitoring gastrointestinal health using a passive air-sampling device positioned on top of a toilet tank. The device comprises a gas sensor array, environmental sensors, and a processor configured to collect data during a user's bowel movement. Gas signatures are analyzed using machine learning to identify users and assess gut health without requiring stool handling. A proprietary health score is generated from sensor and contextual data and displayed to the user via a mobile application. The system continuously improves by associating sensor patterns with user-reported symptom classifications and retraining its algorithms to detect gastrointestinal conditions. The neural-network-enabled gas sensor produces multidimensional digital fingerprints of sampled gas compositions, enabling condition screening based on complex patterns rather than predefined biomarkers. The application includes a goal-setting chatbot using cognitive behavioral therapy methods to promote habit change. Data processing is distributed across on-device inference, edge AI, and cloud services.

Resumen de: US20260298945A1

Predicting non-responsiveness of IBD patients The present invention relates to an in vitro method for predicting the responsiveness of an IBD patient to a therapy with an intracellularly acting immunosuppressive agent of interest, wherein a sample is provided from the IBD patient at an initial period of a treatment with the immunosuppressive agent of interest, said sample comprising effector mononuclear cells, and responsiveness is predicted from the difference between a multidrug ABC transporter activity level in the effector mononuclear cells in said sample and a reference transporter activity level. The method is useful in a treatment of IBD, e.g. in monitoring the progress of the disease or in a decision on a shift from an initial treatment with an agent to another agent like csDMARD or tsDMARD.
