Abstract: Use of a compound as shown in formula I in preparation of a medicament for prevention, treatment or amelioration of learning, memory and cognitive impairment of Down's syndrome. The compound as shown in formula I can enhance the learning and memory ability of a Down's mouse, increase the number of synapses in the hippocampus of the Down's mouse, and can restore the damaged phagocytic function of the brain microglia cell of the Down's mouse. Therefore, the compound can be used as a therapeutic medicament to be applied to the symptoms of learning, memory and cognitive impairment of Down's syndrome.

Abstract: Embodiments disclosed herein relate to reagent containers configured to allow for different liquid and solid reagents to be mixed in situ prior to the measurement.

Abstract: Systems and methods for providing spectral measurements are described. In one embodiment, a spectral measuring device comprises at least one radiation source configured to provide N (N?2) linearly independent illuxninant sources characterized by M (M?N) wavelength channels in a predetermined wavelength range; a sensor unit including at least one sensor, configured to be in optical communication with the radiation sources and an object; a memory storing an illuminant characterization matrix including spectral characteristics of the N illuminant sources in the M wavelength channels; and a processor configured to provide spectral responses of the object in the M wavelength channels, based at least in part on the illuminant characterization matrix. The embodiments of the invention can be used to construct a new class of compact spectral measuring devices, such as handheld color measuring devices.
