摘要:
An optical imaging system includes a first diffractive optical element that receives a multi-wavelength beam of light and separates the received beam of light into diffractive orders. The optical imaging system also includes a second diffractive optical element that includes panels displaced along the second diffractive element in at least one direction, where each panel is positioned to receive and pass the multi-wavelength beam of one of the diffractive orders. A refractive optical element is positioned to receive multi-wavelength beams of the diffractive orders that pass through the second diffractive element, and an optical lens that receives the multi-wavelength beams of the diffractive orders that pass through the refractive element and focuses each of the multi-wavelength beams of the diffractive orders to a different location on an image plane at the same time.
摘要:
A mammalian Green Fluorescent Protein (GFP) Reconstruction Across Synaptic Partners (mGRASP) method and system is provided by optimizing synaptic transmelectron microscopicbrane carriers for mammalian synapses. The method and system in one form integrates molecular and cellular approaches with a novel computational strategy to reliably reconstruct neurons in 3D. The method and system allows mGRASP to be applied to both long-range and local microcircuits, analysis of synaptic distribution at the level of single neurons and dendritic compartments within neural cells.

In recognition of the need to develop novel therapeutic agents and efficient methods for the synthesis thereof, the present invention provides novel bifunctional, trifunctional, or multifunctional compounds for inhibiting histone deacetylases, and pharmaceutically acceptable salts and derivatives thereof. The present invention further provides methods for treating disorders regulated by histone deacetylase activity (e.g., proliferative diseases, cancer, inflammatory diseases, protozoal infections, hair loss, etc.) comprising administering a therapeutically effective amount of an inventive compound to a subject in need thereof. The present invention also provides methods for preparing compounds of the invention.
摘要:
A voltage indicator includes a polypeptide sequence comprising a voltage-sensitive opsin domain and a capture protein domain arranged and disposed to capture a fluorescent dye ligand. When the fluorescent dye ligand is captured and the voltage indicator is bound to a cell membrane, an increase in voltage across the cell membrane causes an increase in fluorescent emission.
摘要:
A microscope directs light through an excitation objective to generate a lattice light sheet (LLS) within a sample. A detection objective collects signal light from the sample in response to the LLS and images the collected light onto a detector. Second and third light beams are imaged onto focal planes of the excitation objective and detection objective, respectively. One or more wavefront detectors determine wavefronts of light emitted from the sample and through the excitation objective in response to the imaged second light beam and emitted from the sample through the detection objective in response to the imaged third light beam. A wavefront of the first light beam is modified to reduce a sample-induced aberration of the LLS within the sample, and a wavefront of the signal light emitted from the sample is modified to reduce a sample-induced aberration of the signal light at the detector.
