摘要:
The present invention relates to the discovery, identification and characterization of toxic agents which are lethal to pathogens and methods for targeting such toxic agents to a pathogen or pathogen infected cells in order to treat and/or eradicate the infection. In particular, the present invention relates to toxic agents which target bacteria at different stages of the bacterial life cycle, which are delivered alone or in combination to bacteria or bacteria-infected cells. The invention relates to toxic agents which are lethal to diseased cells and methods for targeting such toxic agents to a diseased cell in order to treat and/or eradicate the disease. The present invention relates to promoter elements which are pathogen-specific or tissue-specific and the use of such promoter elements to achieve pathogen-specific or tissue-specific expression of the toxic agent(s) and/or ribozyme(s) of the present invention. Specifically, the invention relates to the delivery of one or more toxic gene products, antisense RNAs, or ribozymes, or combination thereof. The invention provides a novel system by which multiple pathogenic targets may be simultaneously targeted to cause the death of a pathogen, or cell infected with a pathogen. Further, the invention has important implications in the eradication of drug-resistant bacterium and bacterial pathogens. The invention provides a novel system by which multiple targets may be simultaneously targeted to cause the death of a diseased cell. The invention has important implications in the eradication of drug-resistant pathogens (such as antibiotic resistant bacteria) and drug-resistant diseased cells (such as drug-resistant cancer cells).
摘要:
The present invention relates to multi-ribozymes and their use to target RNA in a tissue-specific, target RNA-specific, or pathogen-specific manner for the treatment of cancers, proliferative disease, and bacterial, parasitic and viral infections. More specifically, the present invention relates to the use of virions and viral vectors to package and deliver DNA encoding the multi-ribozymes to a host. The present invention relates to the use of liposomes and lipid-DNA complexes to deliver DNA encoding ribozymes to a host. Most specifically, the invention relates to the use of target specific virions to package and deliver DNA comprising a target specific promoter and encoding a ribozyme(s) directed to the target organism nucleic acids. The present invention further relates to a novel vectors encoding a multi-ribozyme structure with enhanced 5′ and/or 3′ autocatalytically cleaving ribozymes. The invention further relates to nucleotides encoding a multi-ribozyme comprising one or more ribozyme cassettes which contain one or more trans-acting ribozymes and one or more autocatalytically cleaving ribozyme sequences.
摘要:
In the case of a process for the mechanical cleaning of reusable drinks containers made of glass or plastic, the process comprising one or more washing cycles or zones and rinsing cycles or zones in a cleaning installation, the reusable drinks containers undergo pretreatment before being supplied to the actual cleaning installation. The reusable drinks containers are sprayed with an aqueous cleaning formulation by means of one or more nozzles which produce a spray yet which is directed into the interior of the reusable containers and, in the interior of the reusable containers, is transformed into a spray mist, with the result that the cleaning formulation is distributed uniformly. The pretreatment ensures that even stubborn dirt or microorganisms such as mold or yeasts is/are removed effectively in the cleaning installation.
摘要:
The operation of filling plants for filling drinks or other foods is subject to stringent regulations under the law on foodstuffs. In this connection, an essential aspect is the cleanness of the filling plant, which consists of a filler and a conveyor. To clean a filling plant, it is known to provide four separate cleaning systems with four separate supply stations and control systems as well as line systems.The invention provides, for all partial cleaning systems in a common central cleaning circuit (40a, 57), a common supply station (10) comprising the componentsfresh water container (12)storage containers (13-16)heating station (29)dosing station (27),which can selectively be connected to or disconnected from the cleaning circuit by means of valves and rotary valve flaps, as well as a programme control system (11) as well as a common partial line system.
摘要:
An isolated nucleic acid encoding a SecA protein of M. tuberculosis is provided. This nucleic acid can be a native coding sequence for the SecA protein of M. tuberculosis. A specific example of the isolated nucleic acid is one that encodes a polypeptide comprising the amino acid sequence set forth in SEQ ID NO:2. An isolated fragment of the secA gene that is specific for M. tuberculosis is provided. A purified SecA protein of Mycobacterium tuberculosis is provided. The purified SecA protein of Mycobacterium tuberculosis comprises the polypeptide having the sequence set forth in the Sequence Listing as SEQ ID NO:2. Fragments of the M. tuberculosis SecA protein are provided. A purified mutant SecA protein of Mycobacterium tuberculosis is provided. The invention provides purified mutant M. tuberculosis expressing the mutant SecA protein of the invention. The invention also provides methods of screening for putative M. tuberculosis virulence factors translocated by the SecA protein.
