摘要:
A Field Scanning OCT (FSOCT) system that overcomes the bottleneck of imaging speed through simultaneous (parallel) detection of photons from a sample. This provides phase stability during imaging. The herein-disclosed FSOCT methods and devices detect backscattered photons in parallel simultaneously from multiple locations without relying on mechanical motion to capture them at offset positions at different times. This significantly improves the performance of OCT imaging.

A method for converting animal cells into brown adipose tissue cells is provided that includes transforming the animal cells using an expression vector. The expression vector includes a nucleotide sequence encoding HB-EGF operatively linked to a promoter and a nucleotide sequence encoding ADAM 12 operatively linked to a promoter. Converting animal cells to brown adipose tissue cells can be used to treat obesity or to treat cancer by converting target cells to brown adipose tissue cells.
摘要:
A method and device for reducing gag reflex by applying pressure to a pressure point in the palm of the hand. A splint that holds the hand relatively immobile has a rigid member and an actuating pressure system, such as a solenoid, at the pressure point. The rigid member at least partially immobilizes the human user's palm and fingers. The actuating pressure system is mounted at an inner side of the volar side of the enclosure adjacent to a pressure region of the palm. A power supply is connected to the actuating pressure system to apply an electrical current to the pressure system, which exerts pressure to the pressure region of the user's palm in order to diminish or normalize the user's gag reflex response.

Metal-organic framework-based molecular sieves comprising pores with a temperature-adjustable pore opening. The temperature-adjustable pore size molecular sieves comprise a plurality of metal clusters bound with a plurality of amphiphilic ligands, each ligand comprising a functionalized hydrophobic moiety and a functionalized hydrophilic moiety, and wherein the metal clusters and amphiphilic ligand hydrophilic moieties form a metal cluster layer, the metal cluster layer forming at least one hydrophilic pore. On each side of the metal cluster layer, a plurality of associated amphiphilic ligand hydrophobic moieties cooperate with the metal cluster layer to form a tri-layer and a plurality of tri-layers are held in proximity with each other to form at least one hydrophobic chamber. The hydrophobic moieties form temperature-adjustable pore size hydrophobic pores. When adjusted to a pre-selected temperature the temperature-adjustable pore openings allow for the passage of molecules having a size less than the size of the pre-selected temperature-adjustable pore opening.
摘要:
The present invention provides novel methods and materials for detecting the presence of a fungus in a biological sample. The inventive methods and materials exploit the fact that the amino acid sequence of the saccharopine dehydrogenase molecule is highly conserved in fungi. Inventive hybridization probes, nucleic acids, PCR primers, antibodies, epitopes, reagents and methods are provided.
摘要:
Ice nucleating agents are introduced into or on invertebrates. They elevate the supercooling point of such invertebrates. Where such invertebrates are freeze-intolerant, they may be killed or made susceptible to freezing by subjecting them to temperatures at or below the elevated supercooling point. Food sources treated with ice nucleating agents can be used to introduce the agents effectively to the invertebrate.

摘要:
Electromagnetic radiation (10) is provided in a gas mixture (12) including helium in the X(1) state and nitrogen in the Y(1) state. The helium is pumped to excite a high population density of its atoms from the X(1) state to the X(2) state; and photons (15) of suitable frequency are injected into the mixture (12) to excite, via a three-body radiative collision of an atom of X(2) with a molecule of Y(1) and a photon (15): a high population density of molecules of the nitrogen from the Y(1) state to the Y(3) state, followed by a substantially simultaneous return of a substantial portion of the excited helium atoms to the X(1) state and a substantial depopulation of the Y(3) state of the nitrogen, causing the molecules thereof to drop to the lower energy Y(2) state, thereby stimulating the emission from the nitrogen of two photons (10) at the same wavelength for each absorbed photon (15), and thus providing a total quantity of photon emission (10) with sufficient gain for amplification of electromagnetic radiation (10), and finally resulting in the depopulation of the molecules in the Y(2) state by autoionization.
