A variant NS1 protein from H5N2 avian influenza virus suppresses PKR activation and promotes replication and virulence in mammals

Emerging Microbes and Infections, 2022
Highly pathogenic avian influenza viruses (HPAIVs) frequently receive global attention as threats to public health. The NS1 protein is a key virulence factor known to impair host antiviral responses.

Occurrence and speciation of mercury in the recent sediments of the western coastal area of the Gulf of Trieste (northern Adriatic Sea): is the legacy of historical mining still present?

, 2023
Mercury (Hg) contamination in the northern Adriatic Sea (Italy) is still an issue of environmental concern due to historical mining at Idrija (Slovenia) which was the second largest Hg mine worldwide (Covelli et al., 2001).

Identification of mercury species via thermodesorption in environmental samples from a tetrahedrite historical Cu-Sb(-Ag) mining site (Mt. Avanza, Friuli Venezia Giulia, Italy)

, 2023
Fahlore minerals of the tetrahedrite-tennantite series are common constituents of a variety of mineral deposits. The chemical formula of tetrahedrite (TTR) is Cu6[Cu4(Fe,Zn)2]Sb4S13 and can host high quantities of several trace elements such as Ag, As ...

Transfer of maternal antibodies against avian influenza virus in mallards (Anas platyrhynchos).

PLoS ONE, 2014
Maternal antibodies protect chicks from infection with pathogens early in life and may impact pathogen dynamics due to the alteration of the proportion of susceptible individuals in a population.

May mercury availability to methylation in contaminated sediments be reduced by using biochar as an amendment? Preliminary evidences from laboratory experiments

, 2023
Among potentially toxic trace elements introduced in the environment by both natural and anthropogenic sources, mercury (Hg) is a contaminant of major concern due to its toxicity and relatively high bioavailability of its most toxic chemical form ...

Search for stable ferromagnets among AIV/Fe digital alloys (AIV = Si, Ge) using first-principles calculations [PDF]

, 2012
Using first-principles electronic structure calculations we investigate the existence of stable ferromagnets among the AIV/Fe digital alloys (AIV=Si,Ge), modeled as periodic sequence of Fe monolayers in the AIV host.
