US Classification:

Abstract:

An apparatus for and method of performing multi-photon light sheet microscopy (MP-LISH), combining multi-photon excited fluorescence with the orthogonal illumination of light sheet microscopy are provided. With live imaging of whole and zebrafish embryos, the high performance of MP-LISH compared to current state-of-the-art imaging techniques in maintaining good signal and high spatial resolution deep inside biological tissues (two times deeper than one-photon light sheet microscopy), in acquisition speed (more than one order of magnitude faster than conventional two-photon laser scanning microscopy), and in low phototoxicity are demonstrated. The inherent multi-modality of this new imaging technique is also demonstrated second harmonic generation light sheet microscopy to detect collagen in mouse tail tissue. Together, these properties create the potential for a wide range of applications for MP-LISH in 4D imaging of live biological systems.

Abstract:

A system and method for communicating content to users that includes a prioritizer and a listing module communicating the category and content identifier for a content to the prioritizer. The prioritizer associates a lifecycle having a plurality of lifecycle states with the category, assigns a first priority to the content in response to a first lifecycle state of the plurality of lifecycle states, changes the first lifecycle state to a second lifecycle state and changes the first priority to a second priority in response to changing the first lifecycle state to the second lifecycle state.

US Classification:

359385, 359368

Abstract:

An apparatus for and method of performing light sheet microscopy (LISH) and light scanning microscopy (RAPS) in a single device are provided. The dual-mode imaging microscope allows for the use of both LISH and RAPS in a single instrument. This dual-mode device will allow researchers to have access to both types of microscopy, allowing access to the widest possible selection of samples. In addition, the device will reduce the high costs and space requirements associated with owning two different microscopes (LISH and RAPS).

US Classification:

83 22, 83 78, 83168, 382128

Abstract:

The present invention relates to a microscope coupled tissue sectioning system. The tissue sectioning system includes a frame for coupling with a microscope. A sample cutting apparatus is attached with the frame. The sample cutting apparatus includes a sample cutter (e.g., blade) and is operable for causing the sample cutter to engage with the sample and remove a portion of the sample. Additionally, a sample moving apparatus attached with the frame. The sample moving apparatus is operable for causing the sample to align with an imaging path of a microscope for imaging by the microscope.
