Abstract:
A display device includes a display module, a light source module and a guiding optical film. The display module includes a first substrate, a second substrate and a display medium. The light source module generates directional light. The display module has a vertical electric field. The display medium is optically isotropic, and the display medium is optically anisotropic when driven by the vertical electric field. The directional light is not perpendicular to the first substrate when the directional light enters the display nodule. The directional light is not perpendicular to the second substrate when the directional light exits the display module. The guiding optical film is disposed on the second substrate and has a light incident surface and a light emitting surface. After the directional light exits the guiding optical film, emitting light is formed, and the emitting light and the light emitting surface has an included angle there between.

A lamp driving device is provided for driving plural lamps. The lamp driving device includes a power conversion circuit and plural lamp connectors. The power conversion circuit is capable of converting an input voltage into a first DC voltage, and outputting a first current having a constant current value. The plural lamp connectors are serially connected with each other, and have respective positive terminals and respective negative terminals connected with corresponding lamps, thereby outputting respective output voltages and respective output currents to corresponding lamps. The first DC voltage is subject to voltage-division to obtain the output voltages, and the magnitudes of the output voltages from the lamps are substantially identical.

A LED current-controlling circuit includes a first magnetic amplifier, a first current detecting circuit, a first magnetic amplifier controller and a first diode. The first magnetic amplifier is connected to an input terminal of the LED current-controlling circuit and the first LED string. The first current detecting circuit is connected to the first LED string in series for detecting the first current flowing through the first LED string.

The first diode is connected to an output terminal of the first magnetic amplifier, the first LED string and the first magnetic amplifier controller. The first magnetic amplifier controller controls on/off statuses of the first magnetic amplifier according to the magnitude of the first current, thereby maintaining the first current at a specified DC current level.

A brightness-adjustable LED driving circuit includes a rectifying and filtering circuit, a power factor correction power conversion circuit, and a detecting and controlling circuit. The rectifying and filtering circuit is used for filtering and rectifying a brightness adjusting voltage into a first DC voltage. The power factor correction power conversion circuit is electrically connected to the rectifying and filtering circuit and at least one LED string for generating an output current required for powering the at least one LED string. The detecting and controlling circuit detects phase data of the brightness adjusting voltage and the output current generated by the power factor correction power conversion circuit. The detecting and controlling circuit generates a control signal to the power factor correction controller according to the phase data of the brightness adjusting voltage, so that the magnitude of the output current is changed according to the phase data of the brightness adjusting voltage.

The present invention relates generally to the field of human genetics. Specifically, the present invention relates to methods and materials used to detect a human sporadic DCM predisposing gene, specifically the dystrophin gene, some mutant alleles of which cause susceptibility to sporadic DCM. More specifically, the invention relates to germline mutations in the dystrophin gene and their use in the diagnosis of predisposition to sporadic DCM. The invention also relates to the prophylaxis and/or therapy of sporadic DCM associated with a mutation in the dystrophin gene. The invention further relates to the screening of drugs for sporadic DCM therapy. Finally, the invention relates to the screening of the dystrophin gene for mutations/alterations, which are useful for diagnosing the predisposition to sporadic DCM.
Abstract:
In our research, two commercially available compounds, 3-amino-1,2,4-dithiazole-5-thione (1) and xanthane hydride (2), and their derivatives 3-6 are found to be potential sulfur-transfer reagents. The efficiency and optimization of these new sulfur-transfer reagents were investigated by solid-phase syntheses of dinudeotide and oligonucleotide phosphorothioates. The results show that both compounds 1 and 2 are highly efficient sulfurizing reagents, and better than 99% sulfur transfer efficiency can be achieved at each step. In contrast to Beaucage reagent, these novel sulfur-transfer reagents are very stable in various solvents, and are available in bulk quantities at low cost. Due to these advantages, compounds 1 and 2 can be considered alternatives to Beaucage reagent, especially in large-scale preparation of oligonucleotide phosphorothioates. Furthermore, compounds 1 and 2 were modified to enhance their solubility in acetonitrile. Three types of structure, as described as Formulae I, II, and III, are considered as potential efficient sulfur-transfer reagents based on our results.
Abstract:
The present invention comprises an improved method of synthesizing oligonucleotides. The method comprises employing dinucleotides (or "dimer blocks") as the basic synthetic unit building block. The method results in extremely high purity oligonucleotides in which the N-1 content is very low, generally less than 1-2% of the full length, N, oligonucleotide. We have found that synthesis using dinucleotide phosphorothioates results in oligonucleotides having very little phosphodiester content. Furthermore, we have found that the amount of dimer required in each coupling step can be less than about 6 and is preferably about 2 equivalents. Synthesis of oligonucleotides according to the dimer block approach described herein can also be conducted without the capping step that has heretofore been deemed necessary after each coupling.

Abstract:
New methods of loading solid supports for oligonucleotide synthesis are presented. The new methods comprise coupling a succinylated nucleoside to a solid support using diisopropylcarbodiimide (DIC) as an activator and N-hydroxybenzotriazole (HOBT) as an acid catalyst. DIC is substantially cheaper than the currently used activating agent, 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (DEC). Furthermore, in the preferred embodiment, when it is used in combination with HOBT, coupling is more efficient, requiring less nucleoside to achieve the same loading densities as in the prior art. The loading process is faster than prior art methods and the overall cost savings of about 43% are realized.
