摘要:
This invention relates to a method of isolating deletion mutants of Vibrio cholerae ,wherein the deletion is predetermined by digestion with restriction endonucleases of known specificity. The deletions are inserted into the Vibrio cholerae chromosone by in vivo recombination between a plasmid carrying the desired deletion, with adjacent flanking sequences, and the Vibrio cholerae chromosome. The invention includes the isolation and characterization of a new Vibrio cholerae strain having a deletion in the tox gene, as defined by Acc I, Xba I, C/a I and/or restriction endonuclease sites.
摘要:
The present disclosure provides methods and compositions for inducing an immune response that confers dual protection against infections by either or both of a rabies virus and a coronavirus, and/or which can be used therapeutically for an existing infection with rabies virus and/or a coronavirus to treat at least one symptom thereof and/or to neutralize or clear the infecting agents. In particular, the present disclosure provides a recombinant rabies virus vector comprising a nucleotide sequence encoding at least one coronavirus immunogenic glycoprotein fragment, as well as pharmaceutical compositions comprising the vaccine vectors.

A hemostatic putty for treatment of a variety of wounds topographies, including but not limited to highly three dimensional wounds, for example gunshot wounds and impalements, is disclosed. The putty is comprised of a matrix polymer weakly crosslinked or not crosslinked such that a viscoelastic matrix is formed. The viscoelastic nature of the putty is tunable by the composition and enables the putty to conform to a variety of wound topographies. Likewise, a hemostatic polymer, for example chitosan or hydrophobically modified chitosan, is included in this matrix to impart hemostatic properties and tissue adhesive on the putty. The hemostatic polymers disclosed prevent microbial infection and are suitable for oxygen transfer required during normal wound metabolism.
摘要:
The present invention provides methods of detecting prostate cancer employing biomarkers, including hZIPl, zinc and citrate. Also provided are antibodies to detect hZIPl protein or peptides and an expression vector comprising a genetic sequence effective to increase uptake of zinc into a prostate cell upon expression thereof. Furthermore, methods of treating prostate cancer and of increasing uptake of zinc into a prostate cell are provided.
摘要:
The present invention relates to methods for treating or preventing graft versus host disease (GVHD) in a host subject, with the methods comprising treating either the graft or the host subject or both to reduce the interaction of graft-origin, CD103-expressing cells with cells in the host. The present invention also relates to methods of screening a graft to determine the likelihood of the graft to generate GVHD.
摘要:
A roaming service method for a fast and secure wireless network is provided. In an embodiment of the present invention, an AP, which an STA associates with, transmits security keys needed for roaming to neighbor APs of the AP. When the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided security key. In another embodiment of the present invention, an authentication server transmits security keys needed for roaming to neighbor APs to which the STA is likely to move, so that when the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided security key.
摘要:
A substantially pure mammalian protein, hereinafter "zonulin", that is a physiological modulator of mammalian tight junctions is disclosed, as well as methods for the use of the same.
摘要:
Compounds are described which modulate the tzrosine kinase activity of p56lck and signal transduction pathways in which this enzyme is involved. The invention also relates to compounds which have immunomodulatory activity, e.g., which have immunosuppressant or immunostimulatory activity, and/or which have an antineoplastic effect. The invention further relates to compositions comprising these compounds, and methods of using them.
摘要:
A purified nucleic acid sequence which encodes for a protein having ketolase enzyme activity and has the nucleic acid sequence of SEQ ID NO: 1 or 3, or has a sequence which encodes the amino acid sequence of SEQ ID NO: 2 or 4, as well as vectors and host cells containing them. Methods of use of the nucleic acid sequences to produce ketocarotenoid in host cells and methods of use of the nucleic acid sequences to modify the production of carotenoids in a host cell are included.
