Abstract: A method for predicting whether a patient with cancer is likely to respond to a treatment is described. The method comprises measuring a value indicative of a level of certain biomarkers; calculating a total value using a weighted sum of the measured values; comparing the total value to a threshold value and when the total value is below the threshold value, determining that the patient is likely to respond to the treatment. Alternatively, the method comprises applying a model comprising coupled ordinary differential equations defining the rate of change of a plurality of biomarkers to predict a plurality of output values for the biomarkers for the treatment; selecting a biomarker; comparing the output value for the selected biomarker to an associated threshold value for the selected biomarker; and when the output value is below the associated threshold value, determining that the patient is likely to respond to the treatment.

Abstract: Devices and methods for inspecting containers for the presence of foreign matter include, in at least one embodiment, at least one sampling head, at least one pressure sensor, and a filter. The at least one sampling head is configured to introduce an amount of a first fluid into a container and to remove an amount of a second fluid from the container for inspection for the presence of foreign matter. The at least one pressure sensor is configured to measure a pressure of the second fluid upon removal of the second fluid from the container. The filter is arranged in the at least one sampling head and is configured to filter the second fluid.
