Animals infected with duck hepatitis B virus may be treated with the 2 min ,3 min -dideoxynucleoside of adenine, guanine, hypoxanthine, 2,6-diaminopurine or various analogs of substituted purines. Several purine 2 min ,3 min -dideoxynucleosides inhibit duck hepatitis B virus in hepatocyte culture >99% at 1  mu g/ml. Potent in vivo efficacy of the 2,6-diaminopurine 2 min ,3 min -dideoxynucleoside for clearance of duck hepatitis B virus from the sera of Pekin ducks is demonstrated. The selective effect on hepadnavirus replication by the purine 2 min ,3 min -dideoxynucleosides is based on the discovery of an unexpected sensitivity of hepadnavirus to purine 2 min ,3 min -dideoxynucleoside analogs. These compounds present a new antiviral therapy of acute or persistent hepadnavirus infections.

Abstract: An electroluminescent device includes a semiconductor layer (4) in the form of a thin dense polymer film comprising at least one conjugated polymer, a first contact layer (5) in contact with a first surface of the semiconductor layer, and a second contact layer (3) in contact with a second surface of the semiconductor layer. The polymer film (4) of the semiconductor layer has a sufficiently low concentration of extrinsic charge carriers that on applying an electric field between the first and second contact layers across the semiconductor layer so as to render the second contact layer positive relative to the first contact layer charge carriers are injected into the semiconductor layer and radiation is emitted from the semiconductor layer. The polymer film can be poly (p-phenyenevinylene) [PPV] of formula (I) wherein the phenylene ring may optionally carry one or more substituents each independently selected from alkyl (preferably methyl), alkoxy (preferably methoxy or ethoxy), halogen (preferably chlorine or bromine) or nitro. A method of manufacture of an electroluminescent device includes steps of depositing a thin layer of a precursor polymer onto a substrate and then heating the precursor polymer to a high temperature to form the conjugated polymer.

Abstract: An exposing device of a color video printer is includes: a mono LCD panel having an image to be printed and a same-sized displaying area; an interval maintaining member attached on the mono LCD panel to make a photoresist medium maintains an uniformed interval on the overall screen between the mono LCD panels; a color filter unit for sequentially receiving the signal voltage corresponding to R,G,B image signals, then forming the mono image and exposing the photoresist medium fixed on one position; and a light source for sequentially examining the R,G,B lights by unifying the lights of R,G,B with the order for applying the R,G,B signal voltages to the LCD panel, thereby printing the colorful images to the photoresist medium.
