摘要:
A new process for stabilizing purified human interferon is described, using propylene glycol. Propylene glycol also aids in the interferon purification procedure. Older methods used stabilizing agents which are toxic, antigenic or irritating. The new process will make available significantly more interferon of clinical purity for use in patients with cancer, viral illnesses and other diseases as yet undesignated (e.g. multiple sclerosis, amyotropic lateral sclerosis, scleroderma, etc.).
摘要:
The presence of neuro-cognitive disorders associated with systemic immunological malfunction are assessed in human patients by determining the level of intracellular RNase L in a sample of the patient's peripheral blood and comparing that level to predetermined levels of RNase L in healthy individuals. Aberrant RNase L levels as compared with those in healthy individuals indicate the presence of neuro-cognitive disorders associated with systemic immunological malfunction. This procedure is useful to distinguish systemic immunological malfunction from primary psychological or neuropsychiatric disorders presenting otherwise similar clinical symptoms.
摘要:
Parenterally administered systemic dsRNAs release host mediators into various compartmentalized biological fluids to combat various microorganisms, particularly viruses, thereby reducing the infectivity and spread of various organisms including those associated with various diseases such as those caused by venereal warts, herpes and HIV.

Hepatitis viral infections are efficaciously treated with mismatched dsRNAs, notably rI.multidot.r(C.sub.11-14,.sup.U).sub.n, alone or in combination with one or more of ganciclovir, coumermycin Al, dideoxyinosine or its nucleoside analogs.
摘要:
dsRNA reduces the phenomenon of viral escape and cellular damage attendant thereto. Viral escape is a process by which a virus of intracellular pathogen alters its host range or indirectly alters its susceptibility to antiviral or immunological therapies. Viruses do so by causing specific changes in their genomic/antigenic composition and/or by causing the elaboration of factors which enhance destructiveness of cells and their ability to multiply progeny virus. Animals susceptible to viral infections and pathology secondary to antigenic drift may have damage reduced by exposing them to dsRNA which prevents or substantially minimizes viral escape brought about through these mechanisms of molecular rearrangement and/or elaboration of factors which break down the natural host defenses.
摘要:
The molten exterior surface portion of a hot dip galvanized steel strip is solidified after the strip is withdrawn from a bath of molten zinc by spraying finely divided particles of a liquid nucleating agent for initiating solidification. The particles are sprayed into an electrostatic field alongside the strip. The particles are initially directed along a path which avoids impingement against the strip. However, the smaller particles are attracted to the strip under the influence of the electrostatic field, to initiate solidification. The larger particles have a momentum along their path large enough to resist the influence of the electrostatic field, thereby permitting the larger particles to continue along a path which avoids impingement. This minimizes the formation of undesirably large spangles and an undesirable surface appearance on the strip.
摘要:
The present invention relates to the induction of interferon production in the cells of living organisms, including human beings. According to the invention, nucleic acid complexes, such as the polyriboinosinate and polycytidylate complex (rI.sub.n .multidot.rC.sub.n), are modified to yield unpaired bases, (uracil or guanine) along the polycytidylate strand which render the complexes more readily hydrolyzable by nucleases present in living cells. The modified complexes retain their ability to stimulate interferon release by the cells but are rendered more vulnerable to destruction within the cells, the modified complexes being significantly less toxic than the original complexes. In addition, polyinosinate strand now has been prepared to contain 5-16% 2'-O-methyl inosinate residues, designated as (rI.sub.5-20, 2'-MeI).sub.n. The new complex (rI.sub.5-20, 2'-MeI).sub.n .multidot.rC.sub.n, exhibits 100-fold more activity than rI.sub.n .multidot.rC.sub.n as an interferon inducer in human cells.
摘要:
A DC superconducting coaxial transmission system provides electrical transmission of 5,000 megawatts of energy while simultaneously delivering liquid hydrogen. The transmission system includes a coaxial transmission segment including an inner superconductor, an outer superconductor disposed in surrounding relation to the inner conductor, and a dielectric insulator disposed between the inner superconductor and the outer superconductor. Liquid hydrogen surrounds the superconductors. Three phase transformers and poly phase rectifier/inverters provide a DC voltage source to the superconductors from the electrical grid. In one embodiment, a switching circuit connected between the voltage source and the superconductor injects a cancellation current component into the direct current flow. The cancellation current component is polarized to flow in a direction opposite to the direct current flow to produce a current zero, thus enabling safe interruption of the high DC current while minimizing the magnitude of transient voltages during switching.

An antiviral/immunomodulatory response in an animal is induced by oral administration to an infected animal, including humans, of a human α-interferon. Methods of conferring resistance or mitigating the effects of exposure to a virus including avian influenza are described.
