Redesign and Validation of a Real-Time RT-PCR to Improve Surveillance for Avian Influenza Viruses of the H9 Subtype

open access: yesViruses, 2022
Avian influenza viruses of the H9 subtype cause significant losses to poultry production in endemic regions of Asia, Africa and the Middle East and pose a risk to human health. The availability of reliable and updated diagnostic tools for H9 surveillance

SUMOylated DDX3 Promotes HBV Replication and Tumor Growth of Hepatocellular Carcinoma via TRIM28‐DDX3‐KLF4α Signaling Axis

open access: yesAdvanced Science, EarlyView.
TRIM28 binds to DDX3 protein to catalyze the SUMOylation of DDX3 (S‐DDX3), thus the S‐DDX3 involves in aberrant alternative splicing of KLF4 mRNA, and the splicing variant KLF4α‐mediated cell cycle and signal transduction, weakens tumor suppressor function of DDX3 protein, which promotes progression of HBV‐HCC.

Mapping hemagglutinin residues driving antigenic diversity in H5Nx avian influenza viruses

open access: yesJournal of Virology
Since its emergence in 1996, the H5 avian influenza virus (AIV) A/Goose/Guangdong/1/1996 (Gs/GD) hemagglutinin (HA) has evolved into over 30 genetically and antigenically distinct clades, including the widespread clade 2.3.4.4b.

Genetic Evolution Characteristics of Genotype G57 Virus, A Dominant Genotype of H9N2 Avian Influenza Virus

open access: yesFrontiers in Microbiology, 2021
This study aimed to investigate the genetic evolution of the H9N2 avian influenza virus (AIV). Whole genome phylogenetic trees were constructed based on 306 H9N2 avian influenza strains collected in China from 2014 to 2019.

Price Transmission and Leadership in the Global Poultry Market: Results From Parametric and Nonparametric Approaches

open access: yesAgribusiness, EarlyView.
ABSTRACT Brazil and the United States account for more than 40% of global poultry exports, with China and South Korea among their major destination markets. This study examines price transmission and market linkages between Brazil and the United States using monthly poultry export price data from January 1990 to December 2024. It also assesses which of

Intra- and interspecies transmission of H7N7 highly pathogenic avian influenza virus during the avian influenza epidemic in the Netherlands in 2003 [PDF]

open access: yes, 2009
The poultry epidemic of H7N7 highly pathogenic avian influenza (HPAI) virus in the Netherlands in 2003 was probably the result of the introduction of an H7N7 low pathogenic avian influenza (LPAI) virus (by interspecies transmission from wild birds) and ...

Discordant correlation between serological assays observed when measuring heterosubtypic responses against avian influenza H5 and H7 viruses in unexposed individuals [PDF]

open access: yes, 2014
The human population is constantly exposed to multiple influenza A subtypes due to zoonotic spill over and rapid viral evolution driven by intrinsic error-prone replication and immunological pressure.

Do More Open Economies Export Less Diversely in Brazilian Agribusiness?

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper asks whether municipalities with a larger export‐to‐revenue ratio display a more concentrated bundle of exported goods in Brazilian agribusiness. Recent advances in export imputation for Brazilian municipalities allow for an analysis of the concentration profile of each municipality and its association with export openness.

Nucleolar localization of influenza A NS1: striking differences between mammalian and avian cells [PDF]

open access: yes, 2010
In mammalian cells, nucleolar localization of influenza A NS1 requires the presence of a C-terminal nucleolar localization signal. This nucleolar localization signal is present only in certain strains of influenza A viruses.
