摘要:
The instant invention provides for novel cationic lipids that can be used in combination with other lipid components such as cholesterol and PEG-lipids to form lipid nanoparticles with oligonucleotides. It is an object of the instant invention to provide a cationic lipid scaffold that demonstrates enhanced efficacy along with lower liver toxicity as a result of lower lipid levels in the liver. The present invention employs low molecular weight cationic lipids with one short lipid chain to enhance the efficiency and tolerability of in vivo delivery of siRNA.
摘要:
Methods are provided for inhibiting stenosis following vascular trauma or disease in a mammalian host, comprising administering to the host a therapeutically effective dosage of a therapeutic conjugate containing a vascular smooth muscle binding protein that associates in a specific manner with a cell surface of the vascular smooth muscle cell, coupled to a therapeutic agent dosage form that inhibits a cellular activity of the muscle cell. Methods are also provided for the direct and/or targeted delivery of therapeutic agents to vascular smooth muscle cells that cause a dilation and fixation of the vascular lumen by inhibiting smooth muscle cell contraction, thereby constituting a biological stent.

摘要:
A method of manufacturing a nanocrystallite from a M-containing salt forms a nanocrystallite. The nanocrystallite can be a member of a population of nanocrystallites having a narrow size distribution and can include one or more semiconductor materials. Semiconducting nanocrystallites can photoluminesce and can have high emission quantum efficiencies.

A novel method of over expressing genes in plants is provided. This method is based on the RNA amplification properties of plus strand RNA viruses of plants. A chimeric multicistronic gene is constructed containing a plant promoter, viral replication origins, a viral movement protein gene, and one or more foreign genes under control of viral subgenomic promoters. Plants containing one or more of these recombinant RNA transcripts are inoculated with helper virus. In the presence of helper virus, the recombinant transcripts are replicated producing high levels of foreign gene RNA.

A novel means for DNA compaction is provided. The object is accomplished by providing a fullerene derivative having 1 to 4 nitrogen-containing hydrophilic side chain(s) or its salt for DNA compaction. DNA compaction can be achieved effectively, and application to gene therapy is also expected.
摘要:
The invention provides systems containing a sterile container for aspiration, filtering, treating and reinjection into a subject of a bodily fluid in a sterile environment. The systems are particularly designed to facilitate transfection of cells within the sterile container by gene therapy molecules and reinjection of the transfected cells into the donor at controlled depth in precisely controlled volumes such as is useful for revascularization of ischemic cardiac tissue. For injection, a pressure actuator, preferably hand-held, applies force to liquids held within the sterile container in precisely controlled increments, thereby expressing liquids through a hollow needle or injection catheter in precisely controlled microvolumes. The invention systems include a hand-held injection device with audible cues that correspond to an operator-selected injection volume and/or audible cues that correspond to needle penetration depth selected by the operator.

摘要:
The invention describes compositions and methods of use in which an infectious modified Tobacco Mosaic Virus (TMV) virion comprising a coat protein (CP) or a movement protein (MP) gene is replaced with a nuclear inclusion protease (NIa) expression cassette for the expression of a heterologous peptide in a tobacco mosaic virus (TMV) host plant.
摘要:
A method and solution for perioperatively inhibiting a variety of pain and inflammation processes at wounds from general surgical procedures including oral/dental procedures. The solution preferably includes multiple pain and inflammation inhibitory at dilute concentration in a physiologic carrier, such as saline or lactated Ringer's solution. The solution is applied by continuous irrigation of a wound during a surgical procedure for preemptive inhibition of pain and while avoiding undesirable side effects associated with oral, intramuscular, subcutaneous or intravenous application of larger doses of the agents. One preferred solution to inhibit pain and inflammation includes a serotonin2 antagonist, a serotonin3 antagonist, a histamine antagonist, a serotonin agonist, a cyclooxygenase inhibitor, a neurokinin1 antagonist, a neurokinin2 antagonist, a purinoceptor antagonist, an ATP-sensitive potassium channel opener, a calcium channel antagonist, a bradykinin1 antagonist, a bradykinin2 antagonist and a null-opioid agonist.
