摘要:
Luminescent semiconductor quantum dots (QDs) conjugated with biomolecules to serve as sensitive probes for early detection of the cancer cells, specifically for ovarian cancer and lung cancer, which represents the most lethal malignancies. The luminescence characterization of the bin-conjugated QDs with cancer specific antigens using linkage molecules. Photo-enhancement is measured at various laser density power, temperatures and laser wavelengths.

The invention is drawn to novel gold nanoparticles that are used in a dual optical method for sensitive and selective detection of antigens. The gold nanoparticle aggregates are synthesized from gold hydrochloride and sulfur salts in an aqueous solution. The aggregates can be selectively sized using a spectral notch filter that results in an improved product with versatile uses. The gold nanoparticles can also be used in improved optical communications devices.

The invention is drawn to a method of using nanoparticle aggregates to form sensors and optical filters. Properly sized (60 and 200 nm) nanoparticle aggregates with cores having a sulfur-oxygen molecular species and a shell with a surface in contact with the core are obtained. Those nanoparticle aggregates have a first resonance profile to wavelengths between 350 nm and 1075 nm. A modified resonance profile for those nanoparticle aggregates is determined. The nanoparticle aggregates are then selectively sized by irradiating them with electromagnetic energy at sufficient intensity and spectral content to modify the first resonance profile towards the modified resonance profile. The resulting nanoparticle aggregates can be used as sensors or optical filters at a selected wavelength.

摘要:
The present disclosure provides methods for treating a subject having a HER2 non-amplified (HER2-negative) cancer or low HER2 expressing (HER2-low) cancer, comprising detecting expression of a BCAR4 gene fusion in a biological sample from the subject. If expression of the BCAR4 gene fusion is detected, a HER2-targeted cancer treatment is administered to the subject; if expression of the BCAR4 gene fusion is not detected, a cancer treatment that is not HER2-targeted is administered to the subject. Methods of predicting response to a HER2-targeted cancer treatment and detecting BCAR4 or BCAR4 gene fusion activation are also provided.

The present invention discloses an air energy boiler and belongs to the technical field of energy conversion. A crankshaft of the boiler is fixed at the output end of a rotating unit. The crankshaft is provided with at least one bulge. A driving piston of each conversion assembly is arranged in an air cavity in a reciprocating motion. The driving piston divides the air cavity into a first cavity and a second cavity. A wrist pin is arranged in the second cavity, and the wrist pin is fixed and connected with the driving piston. Both ends of a piston rod is rotatably connected with the wrist pin and the corresponding bulge respectively. The first cavity is provided with an air intake. Multiple heating pipes are in communication with the first cavity at one end and stretch into the boiler body at the other end. The boiler body is sealed and stores water, and the boiler body is provided with a steam outlet, wherein the steam outlet of the boiler body is connected to various terminals through the use of pipelines. Since air is used as the heat source, no conditional limitations exist for installation, and it is safe to use and saves energy and electricity.

The therapeutic eye mask includes a multi-layer composite main body having a heater plate and a plurality of vibrators mounted therein. The heater plate is located over the wear's eyes when the mask is worn. The vibrators are located in upper locations relative to the heater plate. The heater plate and the vibrators are operated by a pulse control circuit and a timer which are operative by an electrical controller connected to an electrical supply with a USB connector. A space cloth plate and a plurality of magnet disks are provided in the main body. The electrical controller has a first switch operative to connect the eye mask to the electrical supply and a second switch is operative to facilitate the user in choosing selective massage motions to provide effective therapeutic operation.
