摘要:
The present invention is directed to a device that comprises a biomolecular processor and one or more nanotubes. Each biomolecular processor comprises a bioreactor chamber defined by a solid substrate, a plurality of spaced support structures within said bioreactor chamber and attached to the solid substrate, and one or more capture molecules immobilized to some or all of said plurality of spaced support structures, said one or more capture molecules suitable to bind to a portion of a target nucleic acid molecule in a sample. The device also comprises one or more nanotubes defined by the solid substrate and fluidically coupled to the bioreactor chamber.

Lipoxin A4 and its analogs have been discovered to promote the cell proliferation of cornea endothelial cells, and thus promote the proper functioning of the labile tissue layer of cornea endothelial cells. These lipoxin compounds can be administered alone or in combination with other known compounds as a solution that can be topically administered to decrease the swelling of the cornea or maintain the clarity of the cornea. Lipoxin A4 or its analogs can also be combined with other known nutritive compounds to form a solution for storage of a cornea prior to transplantation.
摘要:
New RNA cap analogs are disclosed containing one or more phosphorothioates groups. The analogs also contain modifications at the 2′-O position of 7-methylguanosine that prevent them from being incorporated in the reverse orientation during in vitro synthesis of mRNA and that hence are “anti-reverse cap analogs” (ARCAs). The ARCA modification ensures that the S atom is precisely positioned within the active sites of cap-binding proteins in both the translational and decapping machinery. The new S-ARCA analogs are resistant to in vivo decapping enzymes. Some S-ARCAs have a higher affinity for eIF4E than the corresponding analogs not containing a phosphorothioate group. When mRNAs containing the various S-ARCAs are introduced into cultured cells, some are translated as much as five-fold more efficiently than mRNAs synthesized with the conventional analog m7GpppG.
摘要:
A recombinant herpes simplex virus type-1 (HSV-1) has been constructed that carries a deletion of one of the two viral gamma1 34.5 genes and other immediate early genes, which render the virus able to selectively replicate in cancer cells but not efficiently replicate in normal cells, and in which specific mutations have been introduced to enable the virus to spread among cancer cells by virus-induced fusion. Specifically, syncytial mutations have been introduced in the genes coding for glycoprotein B and glycoprotein K of the virus, enabling high replication and spread of the virus in cancer cells in the presence of substantially lower amounts of gamma1 34.5 protein, which is required for optimum infectious virus produced and virus-induced cell fusion. These altered viruses or the isolated bacterial chromosomes could be used to treat various cancers including breast, liver, colon, and other tissues.
摘要:
Catalysis is used to reduce levels of radicals, other toxins, and carbon monoxide in cigarette smoke. The catalysis operates efficiently at temperatures typical of tobacco smoke, is formed from nontoxic materials, and is relatively inexpensive. The nanostructured catalyst contains titanium oxide, iron oxide, and calcium oxide. The catalyst comprises a layer of iron oxide in the y form supported on a titanium oxide core. Addition of calcium cations helps to stabilize the iron oxide in the y form. The iron oxide layer is on the order of a few nanometers thick on the surface of the titanium oxide core, in an 'egg-in-shell' structure. The nanocatalyst is highly active in promoting the oxidation of compounds such as hydroquinone, catechol, other hydrocarbons, chlorinated phenols, semiquinone radicals, and carbon monoxide, at room temperature and higher temperatures. Catalysis remains active in a pyrolytic or combustion environment for extended periods of time, and has high redox cycling potential. The efficiency of catalysis is not strongly affected by coking in a pyrolytic or combustion environment.
摘要:
The present invention relates to pharmaceutical combinations of opioid and non-opioid analgesics in an intimate admixture with an analgesic from a series of N-acylated 4-hydroxyphenlyamine derivatives, linked via an alkylene bridge to the nitrogen atom of a 1,2-benzisothiazol-3 (2H)-one 1, 1-dioxide group and methods for their use to alleviate pain in mammals. The analgesic combinations exhibit enhanced analgesic potency, do not suppress blood coagulation, and have little hepatotoxic effect.
摘要:
Administration of modified transposon-based vectors has been used to achieve stable incorporation of exogenous genes into animals. These transgenic animals produce transgenic progeny. Further, these transgenic animals produce large quantities of desired molecules encoded by the transgene. Transgenic egg-laying animals produce large quantities of desired molecules encoded by the transgene and deposit these molecules in the egg.
