This invention relates to methods of rapidly detecting influenza, including differentiating between type and subtype. CDC researchers have developed a rapid, accurate, real-time RT-PCR assay that has several advantages over culture and serological tests, which require 5 to 14 days for completion; this assay can also be easily implemented in kit form. To date, hundreds of human cases of infection with the H3N2 variant virus have been confirmed.

Cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines are disclosed. Human induced pluripotent stem cells (hiPSCs) can be generated by reprogramming somatic cells by the expression of four transcription factors. The hiPSCs exhibit similar properties to human embryonic stem cells, including the ability to self-renew and differentiate into all three embryonic germ layers: ectoderm, endoderm, or mesoderm.

The invention pertains to a system for reconstructing images acquired from MR and CT scanners in a robust Gadgetron based cloud computing system. A hardware interface connects clinical imaging instruments (e.g., MR or CT scanners) with a cloud computing environment that includes image data reconstruction and processing software not limited by the computational constraints typical of static hardware with finite processor power.

Chikungunya virus (CHIKV) is mosquito-borne alphavirus endemic in Africa, India, and Southeast Asia. In 2013 CHIKV infection has also emerged in the Caribbean and a pandemic of CHIKV has re-emerged in the Philippines following Typhoon Haiyan. Currently, there is no vaccine available for the prevention of CHIKV infection and no specific therapy exists to treat the illness.

CDC researchers have developed a Madin-Darby Canine Kidney (MDCK) reporter cell line that is exceptionally permissive for influenza virus replication and provides a highly specific, sensitive approach for the simultaneous detection and isolation of influenza viruses. Simplified antibody neutralization assays and high-throughput antiviral drug screening can also be easily and efficiently implemented using this reporter system.

This technology relates to the field of radioactive, isotopically-labeled calcofluor derivatives and uses of such compounds to detect a broad spectrum of filamentous fungi including pathogenic species such as Aspergillus and Mucorales, by diagnostic imaging methods such as positron emission tomography (PET) scanning.

In various x-ray imaging methods, including scattering correction and phase contrast imaging, intensity modulation in space is introduced into the projection images by the use of masks, gratings, or apertures. The present invention relates to a process to demodulate the modulation. The current demodulation processes are either to remove the modulation pattern through digital processing or to move the modulation pattern on the detector in a series of images that requires mechanical movements of a component and tends to lose some information of the imaged object.

The present invention relates to improving x-ray phase contrast imaging. The invention discloses a novel grating interferometer for phase contrast imaging with hard x-rays that overcomes limitations in the level of sensitivity by utilizing the advantages of far-field interferometers. The novel design and fabrication process can easily acquire absolute and differential phase images of lightly absorbing samples.

The magnetic resonance imaging (MRI) systems are used for a variety of imaging application. The present invention discloses an improving MRI device and method by amplifying signals received by resonant NMR coils of MRI systems. It utilizes positive feedback from low-noise Field-Effect Transistor to amplify the signal current that can be coupled out to receiving loops positioned externally without loss in sensitivity. Therefore, the NMR coil can be flexibly positioned near internal tissues and used to develop high-resolution images in highly invasive situations.

The invention pertains to a technique for enhancing the resolution of images in light sheet microscopy by adding additional enhanced depth-of-focus optical arrangements and high numerical aperture objective lenses. The technique employs an arrangement of three objective lenses and a processor for combining captured images. The image composition utilizes the greater resolving power of the third high numerical aperture objective lens by imaging the light sheet and enhanced depth-of-focus arrangement resulting in improved overall resolution of the light sheet system.
