CHROMATIN HIGHER-ORDER STRUCTURE. In the context of chromatin, “higher-order structure” may be defined as any assemblage of nucleosomes that assumes a reproducible conformation in 3D space. The most obvious chromatin higher-order structure is the mitotic/meiotic chromosome in which the DNA is compacted some 10,000- to 20,000-fold.

Nucleic acid detection using structured probes

Disclosed are compositions and a method for detection of nucleic acid sequences. The disclosed method uses a structured probe to distinguish between sequences. Structured probes are bifunctional molecules where one function is as a probe to a target nucleic acid sequence and the other function is as a detection sequence to facilitate detection of the probe. Structured probes include a detection sequence, sequence complementary to a target sequence, and sequences that form duplex regions (higher order structures). The duplex region is stable unless the probe hybridizes to the target sequence. The disclosed method involves hybridizing the structured probe to a target sequence and detecting the detection sequence on the structured probe. The detection sequence is available for detection only if the duplex region of the structured probe is disrupted. This links detection of the structured probe with the hybridization of the structured probe to the target sequence.

Methods for producing three dimensional, self-supporting, light redirecting roof lighting systems

A self-supporting roof lighting system that accepts low elevation light and rejects high elevation light may be produced by making arrays of parallel laser cuts through, or partly through, a flat sheet of transparent acrylic, cutting the segment containing the arrays from the sheet, positioning the segment over linear heating elements to soften the acrylic along the lines between adjoining laser cut arrays, folding the segment along the softened lines through the angle necessary to form a multi-faceted structure of saddle, pyramid or higher order form and allowing this structure to cool and solidify to produce a self-supporting angle-selective roof lighting system with an array of light redirecting laser cuts on each facet. The sequence of the method may be changed so that a saddle, pyramid or higher order structure is first formed by folding or moulding transparent acrylic and, subsequently, an array of parallel laser cuts is made in each facet of the structure to produce an angle-selective roof lighting system. A conical angle-selective roof lighting system may be produced by making concentric laser cuts through, or partly through, a disc of transparent acrylic with a segment cut out, softening the laser cut disc and moulding the disc into conical form.

Circular Dichroism Fluorescent Microscope

According to a circular dichroism fluorescent microscope 100, in one embodiment of the present invention, it is possible to analyze, by using a small amount of a sample and directly in a living organism, a high-order structure of the sample such as a biomolecule, for example, protein and the like. The circular dichroism fluorescent microscope includes a confocal section. In the circular dichroism fluorescent microscope, a circularly polarizing / modulating section converts, into right and left circularly polarized lights, a light beam emitted from a light source. Thus obtained right and left circularly polarized light is focused on the sample so that the sample is irradiated with the right and left circularly polarized lights. Then, an optical lens focuses fluorescence emitted from the sample. Further, a wavelength selecting section transmits only fluorescence having a predetermined wavelength. Subsequently, the fluorescence having passed through the wavelength selecting section is detected. Based on fluorescent intensity signals of the fluorescence thus detected, a difference between an intensity of the fluorescence emitted from the sample at the time of irradiation with the use of the right circularly polarized light and an intensity of the fluorescence emitted from the sample at the time of irradiation with the use of the left circularly polarized light is calculated.
