Abstract: The present invention relates to a controller unit and methods for controlling an insulin pump. The controller unit includes a user input that receives a gain factor. The gain factor has been calculated based on historical data in relation to a patient. The controller unit includes a measurement input for receiving data representative of a measured blood glucose level for the patient. Processing logic of the controller unit is configured to apply the measured blood glucose level to a pancreatic beta-cell insulin secretion computational model to predict an insulin output level, apply the gain factor to the predicted insulin output level to determine a patient insulin deficiency level, and calculate a control signal for controlling the insulin output level of the insulin pump based on the patient insulin deficiency level. Methods are provided for optimizing the gain factor based on the historical data in relation to the patient.

Abstract: Apparatus comprising a module for detecting a single nucleotide polymorphism, SNP, within a genome and comprising: four reaction chambers for receiving a fluid sample, the reaction chambers each containing a different one of the bases A, C, G, T, and a primer; a reference electrode which in use is immersed in said fluid sample; a pair of Ion Sensitive Field Effect Transistors, ISFETs, associated with each reaction chamber, the ISFETs of each pair comprising respective sensing membranes, or a common sensing membrane, exposed within the associated reaction chamber; and a plurality of difference detectors, each difference detector having a pair of inputs coupled respectively to outputs of ISFETs associated with different reaction chambers.

Abstract: A method of selecting a product suited to an individual. The method includes: identifying a product category from a predefined set of product categories, each product category being associated with a set of products; on the basis of said selected product category, selecting a genetic testing cartridge type from a set of available cartridge types, each cartridge type being configured to perform a genotype profiling test on a polynucleotide sample; collecting a polynucleotide sample from the individual; performing a genotype profiling test on said polynucleotide sample using a genetic testing cartridge of the selected genetic testing cartridge type; and using the result of said test to select a product from within the identified product category.
