Immunohistochemical detection of hepatocyte nuclear factor-4α in vertebrates.

Hepatocyte nuclear factor-4α (HNF4α) presents in multiple isoforms generated using alternative promoter (P1 and P2) and splicing. Neither conservation of tissue distribution of HNF4α isoforms, nor presence of alternative promoter usage is known. In this study, to detect the expression of HNF4α in some species of animals, we have applied monoclonal antibodies against P1 (K9218) and P2 (H6939) promoter-driven and P1/P2 promoter-driven H1415 HNF4α for immunohistochemistry and western blot analysis.

Roundabout1 distribution in neoplastic and non-neoplastic diseases with a focus on neoangiogenesis.

Slit and its receptor Roundabout (Robo) are important for neuronal development and neo-angiogenesis in various neoplastic and non-neoplastic diseases. Angiogenesis is a key factor for tumor growth and other angiogenesis-dependent diseases including rheumatoid arthritis, and chronic inflammation Recently, over-expression of Slit/Robo1 family proteins has been reported in several types of malignancy. We explored the expression of Robo1 in neoplastic and non-neoplastic diseases with a focus on newly formed blood vessels.

Effectiveness of four types of neuraminidase inhibitors approved in Japan for the treatment of influenza.

Background: Neuraminidase inhibitors (NAIs) effectively treat influenza. The clinical effectiveness of four NAIs (oseltamivir, zanamivir, laninamivir, and peramivir) was evaluated against influenza A/H1N1pdm09, A/H3N2, and B viruses. Additionally, fever duration in patients infected with oseltamivir-resistant influenza A/H1N1pdm09 with the H275Y mutation was evaluated.

Phylogeographic analysis of human influenza A and B viruses in Myanmar, 2010-2015.

We investigated the circulation patterns of human influenza A and B viruses in Myanmar between 2010 and 2015 by analyzing full HA genes. Upper respiratory tract specimens were collected from patients with symptoms of influenza-like illness. A total of 2,860 respiratory samples were screened by influenza rapid diagnostic test, of which 1,577 (55.

Neuraminidase inhibitor susceptibility and evolutionary analysis of human influenza B isolates from three Asian countries during 2012-2015.

Influenza B viruses of both the Yamagata and the Victoria lineages are implicated in a large proportion of the morbidity and mortality associated with influenza outbreaks. In this study, we characterized the full genomes of 53 influenza B viruses isolated during 2012-2015 in three Asian countries: Japan, Myanmar, and Vietnam. Analysis of the hemagglutinin (HA) genes revealed co-circulation of both the Yamagata and Victoria lineages within the same season in these countries.

Influenza Virus Shedding in Laninamivir-Treated Children upon Returning to School.

The current School Health and Safety Act in Japan states that children with influenza infection should stay home until day 6(th) after symptoms onset. This was an amendment of a previous version recommending school return on day 3 after defervescence. Here, we investigated the duration of fever and virus shedding after laninamivir treatment in 7 children infected with influenza A(H3N2) virus and 21 children with influenza B virus in relation to the school return timing recommended by the School Health and Safety Act during the 2011-2012 influenza season.
