Thermochromic liquid crystal filters are fabricated by providing two polarizers oriented at offset polarity with respect to each other; providing alignment structures adjacent the inner surfaces of the polarizers; placing a plurality of spacers between the polarizers; and filling a space created by the spacers with a thermotropic liquid crystal that acts as a wave block in an isotropic state and acts as a depolarizer in a nematic state. Alternatively, the filters can be created by encapsulating a thermochromic liquid crystal with a polymer material to form a flexible film and orienting the thermochromic liquid crystal in the polymer material to create a structure that functions as a thermochromic optical filter. Such filters can control the flow of light and radiant heat through selective reflection, transmission, absorption, and / or re-emission. The filters have particular application in passive or active light-regulating and temperature-regulating films, materials, and devices, and particularly as construction materials.

The present invention is directed to methods and compositions for blocking the effect of the intronic inhibitory splicing region of intron 7 of the SMN2 gene. The compositions and methods of the instant invention include short oligonucleotide reagents (e.g., oligoribonucleotides) that effectively target sites in the SMN2 pre-mRNA, thereby modulating the splicing of SMN2 pre-mRNA to include exon 7 in the processed transcript. The short target regions are 8-mers and 5-mers and also include the identification of a single nucleotide base that is essential for initiating a long distance stearic inhibitory interactions as well as novel targets distant from intron 7 which block the intronic inhibitory splicing of the same. These short target regions and concomitant inhibitory blocking oligonucleotides are less expensive and easier to manufacture and are small enough to cross the blood brain barrier.

A flow regulator has a pair of side walls extending generally parallel to one another, a bottom wall connecting the side walls to one another and defining an elongate channel for receiving a compressible tube, a roller rotatably and shiftably mounted to the side walls for rolling along the tube in the channel and compressing the tube against the bottom wall. The bottom wall is provided with a formation which varies from a first end of the channel towards an opposite, second end thereof, whereby compressive force applied to the tube via the roller is different at different longitudinal positions of the roller along the channel.

The present disclosure provides a system for conditioning a gaseous supply stream. The system includes a desiccant-free heat and moisture exchange wheel that efficiently transfers both heat and moisture between a warmer, substantially saturated gaseous exhaust stream and a gaseous supply stream such that the supply stream becomes heated and substantially saturated. The presently disclosed conditioning system, therefore, beneficially allows the use of a desiccant-free heat and moisture exchange wheel in applications requiring the transfer of both heat and relatively large amounts of moisture between counter-flowing air streams. The desiccant-free heat and moisture exchange wheel is designed in accordance with the present disclosure to transfer moisture through a process of condensation and re-evaporation. A desiccant-free wheel provides the benefits of being generally easier and less expensive to manufacture than an enthalpy wheel, which is conventionally used in such heat and moisture applications, since an enthalpy wheel includes a coating of desiccant material over its sensible heat exchange media for trapping, transferring, and releasing water vapor between counter-flowing air streams.

The preferred embodiments have six teeth on each gear, and one preferred embodiment also uses balls for the internal teeth. The gears, while rotating at high speeds under load, can intersect throughout a continuous maximum range of 60° or more in any direction.
