An adenovirus, including adenoviral capsid proteins, and a replication-defective adenoviral vector that includes a 5′ retroviral LTR nucleic acid sequence, a 3′ retroviral LTR nucleic acid sequence, a nucleic acid sequence encoding a portion of a retroviral envelope protein adjacent to either the 5′ LTR or the 3′ LTR nucleic acid sequence, a retroviral packaging sequence and a nucleic acid sequence encoding a transgene located between the 5′ LTR and the 3′ LTR is provided. Host cells infected with this adenovirus are also provided. An adenoviral vector is provided that includes an adenoviral polynucleotide sequence comprising a nucleic acid encoding a transgene, a retroviral packaging signal, a 5′ and a 3′ retroviral LTR, and a portion of a retroviral envelope polypeptide, wherein the adenoviral polynucleotide sequence does not encode one or more of E1, E3 or E4. A method for transforming a cell is also provided using a virus or a vector of the invention, as is a method for introducing a transgene into a cell that is not able to produce viral particles with a single viral vector. A method is also provided for preventing or treating disorder in a subject using the adenoviral vectors of the invention. A pharmaceutical composition is also provided that includes an adenoviral vector of the invention and a pharmaceutically acceptable carrier.

Provided are compounds and pharmaceutically acceptable salts thereof, their pharmaceutical compositions, their methods of preparation, and their use for treating viral infections mediated by a member of the retrovirus family of viruses such as the Human Immunodeficiency Virus (HIV).

The invention provides compounds with activity against infectious diseases. The compounds of the invention may inhibit retroviral reverse transcriptases and thus inhibit the replication, of the virus. The compounds of the invention may be useful for treating human patients infected with a human retrovirus, such as human immunodeficiency virus (strains of HIV-l or HIV-2) or human T-cell leukemia virus (HTLV-1 or HTLV-II) which results in acquired immunodeficiency syndrome (AIDS) and / or related diseases. Representative of the invention is a compound of the following formula, with the substituents defined herein:

This invention pertains to a method for treating a human with human immunodeficiency virus infection which comprises administering to the human a therapeutically effective amount of a thymidine analog, which analog acts as an inhibitor of viral reverse transcriptase necessary for viral replication of human immunodeficiency virus, and a thymidylate synthase inhibitor, or pharmaceutically acceptable salts thereof.

Provided are compounds and pharmaceutically acceptable salts thereof, their pharmaceutical compositions, their methods of preparation, and their use for treating viral infections mediated by a member of the retrovirus family of viruses such as the Human Immunodeficiency Virus (HIV).

The invention belongs to the technical field of detection and diagnosis of aquatic animal pathogeny, and discloses a detection kit and detection method for siniperca chuatsi rhabdoviruses. The reverse transcription-polymerase chain reaction type rapid detection kit for the siniperca chuatsi rhabdoviruses is filled with a 5* reverse transcription buffer solution, reverse transcriptase, a random primer, 1.0 mL of 2*reaction mixed buffer solution, a preferably-designed sense primer, a preferably-designed reverse primer, Taq DNA polymerase, a positive control solution, a negative control solution and ddH2O. The novel reverse transcription-polymerase chain reaction type rapid detection kit and detection method for the siniperca chuatsi rhabdoviruses overcome shortcomings of an existing detection method for the siniperca chuatsi rhabdoviruses, are practicable when applied to clinical diagnosis of the siniperca chuatsi rhabdoviruses, have the advantages of rapidity, accuracy and specificity, meet requirements of the clinical diagnosis, and provide convenience for detection of the siniperca chuatsi rhabdoviruses.

Provided are compounds and pharmaceutically acceptable salts thereof, their pharmaceutical compositions, their methods of preparation, and their use for treating viral infections mediated by a member of the retrovirus family of viruses such as the Human Immunodeficiency Virus (HIV).

The present invention provides novel compounds with activity against infectious viruses. The compounds of the invention may inhibit retroviral reverse transcriptases and thus inhibit the replication of the virus. They are useful for treating human patients infected with a human retrovirus, such as human immunodeficiency virus (strains of HIV-1 or HIV-2) or human T-cell leukemia viruses (HTLV-I or HTLV-II) which results in acquired immunodeficiency syndrome (AIDS) and / or related diseases. The present invention also relates generally to the accumulation or retention of therapeutic compounds inside cells. The invention is more particularly related to attaining high concentrations of active metabolite molecules in HIV infected cells. Intracellular targeting may be achieved by methods and compositions which allow accumulation or retention of biologically active agents inside cells. Such effective targeting may be applicable to a variety of therapeutic formulations and procedures.

The present invention relates to methods and compositions having trehalose and DNA polymerase for facilitating the rapid and efficient amplification of nucleic acid molecules and the detection and quantitation of RNA molecules, and for increasing the detection sensitivity and reliability through generation of secure cDNA molecules prior to gene-specific primer dependent amplification. The reagent mixture comprises a ready to use reagent solution, wherein the solution comprises: (a) trehalose in a concentration between about 5% and about 35%; (b) a viral reverse transcriptase; and (c) at least one DNA polymerases, in a buffer suitable for use in a reverse transcription reaction, wherein the buffer comprises a co-factor metal ion and nucleoside triphosphates.
