A packaging cell line capable of complementing recombinant adenoviruses based on serotypes from subgroup B, preferably adenovirus type 35. The cell line is preferably derived from primary, diploid human cells (e.g., primary human retinoblasts, primary human embryonic kidney cells and primary human amniocytes) which are transformed by adenovirus E1 sequences either operatively linked on one DNA molecule or located on two separate DNA molecules, the sequences being operatively linked to regulatory sequences enabling transcription and translation of encoded proteins. Also disclosed is a cell line derived from PER.C6 (ECACC deposit number 96022940), which cell expresses functional Ad35 E1B sequences. The Ad35-E1B sequences are driven by the E1B promoter or a heterologous promoter and terminated by a heterologous poly-adenylation signal. The new cell lines are useful for producing recombinant adenoviruses designed for gene therapy and vaccination. The cell line can also be used for producing human recombinant therapeutic proteins such as human growth factors and human antibodies. In addition, the cell lines are useful for producing human viruses other than adenovirus such as influenza virus, herpes simplex virus, rotavirus, measles virus.

Methods of inhibiting growth of yeast, fungus, bacteria or Herpes simplex virus by topical application of compositions that include an isolated Bacillus species, spores or an extracellular product of a B. coagulans strain are disclosed.

A herpes simplex virus is disclosed in which the herpes simplex virus genome comprises a nucleic acid sequence encoding an ING4 polypeptide.

The use of Herpes Simplex Virus (HSV) in the treatment of tumour by extratumoural administration of said HSV, and the use of HSV in treatment of tumour by combination therapy with a pharmaceutical wherein the HSV and/or pharmaceutical is administered at an extratumoural location, is disclosed.

The invention belongs to the technical field of digital image processing and pattern recognition and particularly relates to a plant disease and pest detection method based on SVM (support vector machine) learning. The plant disease and pest detection method comprises the following steps: acquiring a large number of regularly grown plant leaves and the plant leaves with diseases and pests from a large number of monitoring videos of agricultural scenes; extracting a part of pictures of the regularly grown plant leaves and the plant leaves with diseases and pests as samples; extracting characteristics [including color characteristic, HSV (herpes simplex virus) characteristic, edge characteristic and HOG (histogram of oriented gradient) characteristic] of each leaf picture; combining the characteristics into characteristic vectors; training the characteristic vectors of each leaf picture through an SVM learning method; forming a classifier after training; and detecting the large number of plant leaf pictures by the classifier to detect whether diseases or pests occur to the plant leaves. Compared with a biologic plant disease and pest detection method, the plant disease and pest detection method based on the SVM learning is higher in real time and easier to implement; and the shortcoming of detecting the plant diseases and pests by working in the fields is overcome.

This invention relates to a method for systemic immune activation which is effective for eliciting both a systemic, non-antigen specific immune response and a strong antigen-specific immune response in a mammal. The method is particularly effective for protecting a mammal from herpes simplex virus. Also disclosed are therapeutic compositions useful in such a method.

The invention provides a herpes simplex virus (HSV) vector that does not express toxic HSV genes in non-complementing cells and which comprises a genome comprising one or more transgenes, wherein the vector is capable of expression of a transgene for at least 28 days in non-complementing cells. The disclosed vectors include vectors having deletions in the genes ICP0, ICP4, TCP22, TCP27 and TCP47, or alternative inactivating mutations, or vectors which express one or more of these genes with modified kinetics. The invention also relates to viral stocks of the inventive vectors, compositions thereof suitable for use therapeutically or for in vitro applications, and methods relating thereto. In another aspect, the invention provides a complementing cell, in particular a U20S cell, engineered to express ICP4 and ICP27 when the cell is infected with HSV for the production of the inventive vector. Said cells are disclosed as naturally complementing ICP0.

The present invention provides an HSV having a genome with a mutation of a TAATGARAT sequence such that, in the presence of a ICP4 gene product, a native immediate early gene is expressed from the genome with delayed kinetics, the genome having a further inactivating mutation of each of the genes encoding ICP4.

The invention relates to fatty acid stimulation of rectal mucosa initiating the process of defecation, acting as a laxative. Furthermore, the invention relates to the usage of free fatty acids, fatty acid mixtures and fatty acid extracts from marine lipids in pharmaceutical formulations such as suppositories, ointments, tablets and gelatin capsules for treatment and prevention of multiple disorders like constipation, hemorrhoids, bacterial infections (e.g. helicobacter pylori), viral infections (e.g. herpes simplex virus infections) and inflammations, as well as against fissura ani and pruritus ani.

The present invention provides a recombinant oncolytic Herpes Simplex Virus (oHSV) comprising a non-HSV ligand specific for a molecule (protein, lipid, or carbohydrate determinant) present on the surface of a cell (such as a cancer cell) and one or more copies of one or more microRNA target sequences inserted into one or more HSV gene loci, preferably one or more HSV gene(s) required for replication of HSV in normal (i.e., non-cancerous) cells. The invention further provides stocks and pharmaceutical compositions comprising the inventive oHSV and methods for killing tumor cells employing the inventive oHSV.

An application of indole-2.3-bione in preparing the antiviral medicine for HIV, influenza virus, hemorrhagic virus and herpes simplex virus and the immunopotentiator is disclosed.

A method of treating cancer in a subject is disclosed, the method comprising administration of an oncolytic herpes simplex virus and administration of lymphocyte cells modified to express a chimeric antigen receptor (CAR) or modified to express a T cell receptor (TCR).

The present disclosure generally relates to vaccine compositions for Herpes Simplex Viruses (HSV) types 1 and/or 2. The vaccines comprise isolated antigens or glycoprotein subunits of the viruses, optionally with an adjuvant, such as a cationic liposome DNA complex (CLDC). Also the present disclosure contains methods of vaccinating a subject utilizing these compositions.

Novel immunoregulatory utilities of Escherichi coli heat-labile enterotoxin (LT) are disclosed. This enterotoxin can be used in combination with an unrelated antigen to achieve a higher immune response to said antigen when administered as part of an oral vaccine preparation. By way of example, the efficacy of oral adjuvant therapy of LT in the development of immunological protection against herpes simplex virus was examined. In addition, the ability of LT to influence the induction and maintenance of tolerance in animals primed orally with two unrelated protein antigens administered simultaneously, OVA and BSA was examined. Simultaneous administration of LT with OVA was shown to prevent the induction of tolerance to OVA and to increase the serum anti-OVA IgG response to 30-90 fold over PBS primed and OVA primed animals, respectively.
