摘要:
Provided are devices adapted to isolate, amplify, and detect nucleic acids that may be present in a biological sample. The devices can, in some embodiments, isolate, amplify, and detect nucleic acid in a single chamber. In other embodiments, the devices are adapted to isolate and amplify nucleic acids in a reaction chamber, after which the nucleic acids may be communicated to a pervious medium—such as a lateral flow strip—where the user may label and detect the nucleic acids.

摘要:
Disclosed are methods, devices and systems for biological and chemical sample processing using microfluidic chips. The disclosed microfluidic chips contain at least two detection zones for interacting with pre-selected RNA sequences, DNA sequences, antibodies, or antigens to determine their presence in the sample. Systems are also described comprising a cassette having at least one port and a sample inlet in fluid communication with a detection zone for interacting with pre-selected RNA sequences, DNA sequences, antibodies, or antigens, or mixtures thereof, if present, in a sample. Methods for concurrent testing of at least two of RNA, DNA, antibody, and antigen in a sample are also described, as are methods for testing for pre-selected pathogens and microfluidic methods.

The invention includes compositions comprising substantially purified salivary glycoproteins and carbohydrate ligands thereof which are useful in methods for the treatment and prevention of HIV-1 infection. The invention also includes methods for the treatment and prevention of HIV-1 infection comprising contacting a composition of the invention with a human patient. Additionally, the invention includes antibodies and kits useful in the treatment and prevention of HIV-1 infection.
摘要:
The invention is directed to compositions comprising polyvalent complexes containing a biocompatible polymer backbone to which is attached a plurality of monomeric anti-microbial peptides and to methods for using such complexes to stabilize anti-microbial peptides for treating or preventing a disease or condition resulting from infection with a microbe. Multivalent derivatives of existing antimicrobial peptides in which several peptides are covalently linked have been investigated. The resulting construct may contain up to 30 or more units, and exhibits a significant enhancement of anti-microbial effect relative to the free peptides: on the order of a ten fold improvement in effectiveness, suggesting that higher multimerization can indeed lead to more effective agents. The invention is also directed to the use of such complexes for delivery of anti-viral peptides, in particular, peptides and peptide fragments obtained from salivary agglutinin protein (gp-340) for use in treating or preventing infection with HIV.
摘要:
A remotely controlled drug delivery device administers a dose of a drug, agent or microbicide using a gas pressure delivery system. The device stores multiple doses of the drug or agent. A toroid shaped housing includes three chambers, a gas chamber containing a pressurized gas, a drug storage chamber containing the drug or agent, and an expandable chamber for delivering the drug from the drug storage. The device includes an electronic controller for opening a valve connecting the gas chamber to the expandable chamber for a predetermined period of time in order to deliver a predetermined dose of the drug. The controller communicates with a remote control device via radio frequency. The remote control device sends a signal to the controller, which causes a dose to be delivered. The controller returns a signal to the remote control device indicating that the dose has been delivered and a signal indicating when the device needs to be removed for maintenance. The device may be used in any body cavity to deliver any desired type of drug.
