SIRNA STRUCTURES FOR HIGH ACTIVITY AND REDUCED OFF TARGET
Compounds, compositions, and methods for modulating expression of target genes using RNA interference. RNAi structures and molecules can be used for modulating or silencing the expression of genes, with high levels of RNAi activity and reduced off target actions. Advantageous structures include siRNAs targeted to any gene having one or more 2′-deoxy nucleotides located in the seed region. The RNA interference molecules can be used in methods for preventing or treating diseases.
A production method for a polarizing film according to the present invention includes a step (I) for conveying a PVA sheet in the longitudinal direction while at least stretching, dyeing, and then washing the PVA sheet to produce a stretched PVA sheet that contains water, a step (II) for applying a liquid that includes a water-soluble compound to the stretched PVA sheet that contains water in a state in which the water content of the stretched PVA sheet is x wt% (40 ≥ x ≥ 1.1 × thickness (μm) of stretched PVA sheet) to produce a stretched PVA sheet that has a coating liquid film that is 0.3–2.2 μm thick, and a step (III) for drying the stretched PVA sheet that has a coating liquid film to produce a polarizing film. This production method for a polarizing film makes it possible to impregnate the polarizing film with a water-soluble component without precipitation.
The present invention provides a mirror member which can be easily configured in a complex curved surface shape or the like with good productivity and is excellent in mirror surface properties. The present invention relates to a film mirror laminate having an adhesive layer, a substrate film, a metal reflective layer, and an optical adjustment layer in the stated order, wherein, when light is incident from the optical adjustment layer side at an incident angle of 60° on a sample in which the adhesive layer-side surface of the film mirror laminate is attached to a glass plate, the reflection image clarity at an optical comb width of 0.125 mm is 60% or more.

Provided is a high-quality optical laminate with good yield. This method for manufacturing an optical laminate includes: preparing a first laminate that comprises a substrate, an absorption-type polarizing membrane formed on the substrate, and a protective film that is affixed to the absorption-type polarizing membrane; obtaining a sheet-like first laminate by cutting the first laminate into a prescribed shape; preparing a sheet-like second laminate that comprises a phase difference member having a first principal surface and a second principal surface that face each other, and a first adhesive layer that is disposed on the first principal surface side of the phase difference member; and peeling the protective film from the sheet-like first laminate and affixing the absorption-type polarizing membrane of the sheet-like first laminate to the first adhesive layer of the sheet-like second laminate. The thickness of the absorption-type polarizing membrane is 7 μm or less, and the tensile modulus of elasticity of the protective film is less than the tensile modulus of elasticity of the substrate.
