Background and Aims: The emergence of drug-resistant influenza viruses has become a serious threat for human and animal populations. Glycyrrhiza glabra (Gg) is a traditional medicine clinically used for the treatment of viral respiratory infection symptoms in most countries. We evaluated the effects of the herb on influenza virus replication in human lung cultured cells (A549) following the det...

The H1N1 influenza A virus of swine-origin caused pandemics throughout the world in 2009 and the highly pathogenic H5N1 avian influenza virus has also caused epidemics in Southeast Asia in recent years. The threat of influenza A thus remains a serious global health issue and novel drugs that target these viruses are highly desirable. Influenza A possesses an endonuclease within its RNA polymera...

Widespread resistance among circulating influenza A strains to at least one of the anti-influenza drugs is a major public health concern. A triple combination antiviral drug (TCAD) regimen comprised of amantadine, oseltamivir, and ribavirin has been shown to have synergistic and broad spectrum activity against influenza A strains, including drug resistant strains. Here, we used mathematical mod...

The authors investigated whether thoracic lymphatic pumping (TLP) after FluShield vaccination enhanced the production of anti-influenza immunoglobulins in elderly individuals, who are at particular risk for influenza. Osteopathic students and non-TLP-treated elderly subjects served as controls. Serum antibody titers were quantified with enzyme-linked immunosorbent assay, and hemagglutination in...

A trivalent influenza split vaccine was formulated at high concentration for coating on the transdermal microneedle system. Monovalent bulks of three strains, two and one B strain were diafiltrated, concentrated, lyophilized. The lyophilized powder each separately reconstituted subsequently combined into a formulation vaccine. process converted monovalent with low hemagglutinin (HA) concentrati...

background and aims: influenza a virus of orthomyxoviridae family is able to create pandemic influenza. vaccination is the most effective way to prevent influenza virus infection. matrix protein 2 (m2) is a homotetramer ion channel with 97 amino acids length and highly conserved among influenza viruses and is considered for development of a universal influenza vaccine. materials and methods: we...

We previously identified a series of compounds which specifically inhibited the transcription of influenza A and B viruses (J. Tomassini, H. Selnick, M.E. Davies, M.E. Armstrong, J. Baldwin, M. Bourgeois, J. Hastings, D. Hazuda, J. Lewis, W. McClements, G. Ponticello, E. Radzilowski, G. Smith, A. Tebben, and A. Wolfe, Antimicrob. Agents Chemother. 38:2827-2837, 1994). The compounds, 4-substitut...

Influenza viruses are the worldwide major causative agents of human and animal acute respiratory infections. Some of the influenza subtypes have caused epidemics and pandemics among humans. The varieties of methods are available for the rapid isolation and identification of influenza viruses in clinical and environmental samples. Since nucleic acids amplification techniques such as RT-PCR have ...

Meliae Fructus (MF) is the dried ripe fruit of Melia toosendan Siebold et Zuccarini, Meliaceae family. MF is widely used in traditional medicine to treat inflammation and helminthic infection and has anti-bacterial, anti-oxidant, anti-cancer, anti-inflammatory, and analgesic activities. However, potential anti-influenza properties of MF have yet to be investigated. We determined whether an etha...
