摘要:
A calorie estimating device for measuring a calorie content of a food item is provided. The device comprises a holder substrate, a transmitter antenna configured to transmit ultra-wide band (UWB) signals to at least a portion of the food item disposed on a side of the holder substrate, wherein the transmitter antenna comprises a planar antenna, a first receiver antenna configured to receive at least a portion of UWB signals reflected by the food item, wherein the first receiver antenna comprises a planar antenna, and a second receiver antenna configured to receive at least a portion of UWB signals propagated through the food item, wherein the second receiver antenna comprises a planar antenna.
摘要:
Imaging agents are described that comprise labeled substrates capable of being introduced into cells via the cystine/glutamate antiporter. The substrates may be used for imaging or detecting oxidative stress in cells by introducing the labeled agents into cells via the cystine/glutamate antiporter and subsequent detection.

摘要:
Provided herein are isolated polypeptides derived from the staphylococcal protein A protein B domain comprising a pair of anti-parallel alpha helices that are capable of binding a target. Also provided are nucleic acid sequences encoding such two helix binders, vectors containing the nucleic acid sequences encoding for two helix binders, and host cells transformed with vectors containing the nucleic acid sequences encoding for the two-helix binders. Also provided are methods of using the two helix binders.

摘要:
A system includes an estimating unit to non-destructively estimate a fat content and a water content of a food sample. The system further includes a processing unit operatively coupled to the estimating unit to determine a calorie content based solely on the fat content and the water content of the food sample.
摘要:
An isolated polypeptide, Z domain, derived from B domain of Staphylococcal protein A, comprising a pair of anti-parallel alpha helices that are capable of binding a target, is provided herein. Introduction of an engineered disulfide bridge between two natural or un-natural amino acids in the polypeptide is provided here. Also provided are methods of using the two-helix binders.
