Abstract: In a method for establishing a degree of browning of food to be cooked in a cooking chamber of a household cooking appliance, a reference image is captured by a camera of the household cooking appliance, which camera is directed into the cooking chamber. A first measurement image is captured at a first brightness of a light source of the household cooking appliance, and a second measurement image is captured at a second brightness of the light source. A difference image is generated from the first measurement image and the second measurement image, and the difference image is compared with the reference image.

Abstract: The present invention relates generally to a method of diagnosing, predicting and/or monitoring the development or progress of an inflammatory response in a mammal. More particularly, the present invention relates to a method of diagnosing, predicting and/or monitoring the development or progress of an inflammatory response by analysing one or both of activin or follistatin expression levels either in a subject mammal or in a biological sample derived from said mammal. The present invention further provides a method for predicting, diagnosing and/or monitoring conditions associated with or characterised by the onset of inflammatory response. Also provided are diagnostic agents useful for detecting activin and/or follistatin expression levels.
