[Problem] To provide a method for acquisition of data able to serve as an index for determining the likelihood that an ovarian endometriosis cyst is cancerous. [Solution] This data acquisition method for determining the likelihood that an ovarian endometriosis cyst is cancerous includes an iron concentration measurement step for measuring the iron concentration in the cystic fluid of the ovarian endometriosis cyst. This diagnostic device for diagnosing the likelihood that an ovarian endometriosis cyst is cancerous is provided, at a minimum, with an iron concentration measurement unit for measuring the iron concentration in the cystic fluid of the ovarian endometriosis cyst.

A system for detecting analytes in a test sample, and a method for processing the same, is provided. The system includes a cartridge reader unit that has a control unit and a pneumatic system, and a cartridge assembly that prepares the samples with mixing material(s) through communication channels. The assembly has a memory chip with parameters for preparing the sample and at least one sensor. The assembly, pneumatic system, and control unit operate together to prepare the sample and provide the prepared sample to the sensor for detecting analytes, and also process measurements from the sensor to generate test results.

Genetically encoded calcium indicator (GECI) polypeptides and the nucleic acid molecules encoding such polypeptides are provided. In addition, methods of using such nucleic acids and polypeptides in methods of screening for agonists or antagonists of G-protein coupled receptor (GPCR) or ion channels and methods of monitoring neural activity also are provided.

Affinity sensors may exhibit advantaged regeneration behavior when pH is changed in proximity to a sensing element. Such affinity sensors may comprise at least one sensing element comprising a recognition moiety that interacts with an analyte by reversibly forming an analyte complex, and a solid-state pH-modulating element in proximity to the at least one sensing element, wherein formation of the analyte complex is pH-dependent and the at least one sensing element provides a signal that changes when the analyte complex reversibly forms, and a change in magnitude of the signal is correlatable to an amount of analyte interacted with the at least one sensing element.
