Abstract: An apparatus includes a flow cell, an imaging assembly, and a processor. The flow cell includes a channel and a plurality of reaction sites. The imaging assembly is operable to receive light emitted from the reaction sites in response to an excitation light. The processor is configured to drive relative movement between at least a portion of the imaging assembly and the flow cell along a continuous range of motion to thereby enable the imaging assembly to capture images along the length of the channel. The processor is also configured to activate the imaging assembly to capture one or more calibration images of one or more calibration regions of the channel, during a first portion of the continuous range of motion. The processor is also configured to activate the imaging assembly to capture images of the reaction sites during a second portion of the continuous range of motion.

Abstract: A feeding regimen for an infant which includes (a) providing a first composition comprising a fat or lipid; a protein source, wherein the protein source has from about 72% to about 90% whey and from about 10% to about 28% casein; a prebiotic composition; and at least about 72 IU/100 kcal of vitamin D, (b) instructing that the first composition is to be fed to an infant from birth through 4 months of age; (c) providing a second composition, the second composition comprising: a fat or lipid; a protein source, wherein the protein source has from about 50% to about 70% whey and from about 30% to about 50% casein; a prebiotic composition; and no greater than 70 IU/100 kcal of vitamin D; and (d) instructing that the second composition is to be fed to an infant starting at 4 months of age.

Abstract: A feeding regimen for an infant which includes (a) feeding to a newborn infant a first composition including a fat or lipid; a protein source, wherein the protein source has from about 72% to about 90% whey and from about 10% to about 28% casein; a prebiotic composition; and at least about 72 IU/100 kcal of vitamin D, and (b) feeding to a later stage infant a second composition which includes a fat or lipid; a protein source, wherein the protein source has from about 50% to about 70% whey and from about 30% to about 50% casein; a prebiotic composition; and no greater than 70 IU/100 kcal of vitamin D.

Abstract: The present invention relates to a nutritional supplement for administration to children. The supplement comprises a protein component, a carbohydrate component, and a fat or lipid component which further comprises a source of DHA. The supplement has an ?-6:?3 fatty acid ratio of about 6:1 or less. The present invention also relates to a method of providing nutrition to a pediatric subject comprising administering to the subject a nutritional supplement comprising a protein component; a carbohydrate component; and a fat or lipid component, which further comprises a source of DHA, wherein the composition has an ?-6:?-3 fatty acid ratio of about 6:1 or less.
