Abstract: An intracellular monitoring device (IMD) that fits completely inside a living cell, and causes no significant impairment, to a cell's normal biological processes. The IMD monitors a cell for its level of a biological substance (e.g., calcium ion concentration) of interest. If the biological substance reaches or exceeds a threshold, the IMD transmits an electromagnetic signal, received by an antenna outside the cell. Each IMD has its electromagnetic signal encoded with a unique frequency. Detection of the frequency components, in the signals received by an antenna, permits identification of the source IMD's. A high calcium ion concentration is indicative of a strongly-activated cerebral cortex neuron. Brain tissue is relatively transparent to near infrared, making it a good frequency band, for the electromagnetic signals from neuron-monitoring IMD's. The near infrared of each IMD can be produced by quantum dots, powered by bioelectric catalysis triggered by high calcium ion concentration.

Abstract: Continuous Glucose Monitoring (CGM) devices provide glucose concentration measurements in the subcutaneous tissue with limited accuracy and precision. Therefore, CGM readings cannot be incorporated in a straightforward manner in outcome metrics of clinical trials e.g. aimed to assess new glycaemic-regulation therapies. To define those outcome metrics, frequent Blood Glucose (BG) reference measurements are still needed, with consequent relevant difficulties in outpatient settings. Here we propose a “retrofitting” algorithm that produces a quasi continuous time BG profile by simultaneously exploiting the high accuracy of available BG references (possibly very sparsely collected) and the high temporal resolution of CGM data (usually noisy and affected by significant bias).
