Article Abstract

With the demonstration that AF is highly hereditable and strongly associated with over 100 genetic loci, one step towards personalized treatment of AF is the potential use of genetic testing to predict response to therapy. Although various clinical models have been developed to predict recurrence, none have shown a consistent ability to predict treatment outcomes. This highlights a need for additional patient information to increase predictive value. Here, we review the use of genetic data for prediction of AF recurrence after interventions such as ablation, cardioversion, or drug therapy. We explore the use of other downstream predictors, such as mRNA and protein, as other possible predictive tools. Finally, we assess how this genetic data can further our mechanistc understanding of AF pathogenesis and recurrence.

Integration of multi-omics resources reveals genetic features associated with environmental adaptation in the Wuzhishan pig genome.

In light of the challenges posed by global climate change, the environmental adaptability of organisms is becoming increasingly important. The Wuzhishan (WZS) pig, tolerant to high heat and humidity, is an ideal model for genomic study. By characterizing its genome and assessing its genetic diversity and runs of homozygosity (ROH), we can gain insights into its current conservation status and genomic architecture.

Antarctic krill () is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Climate change is threatening krill populations and their predators, while current catch limits do not take into account climate variability or krill population dynamics. In 2024, CCAMLR was unable to renew its spatial catch limits, highlighting the urgent need for improved management of the krill fishery to prevent any harm to the Southern Ocean ecosystem.

N460S in PB2 and I163T in nucleoprotein synergistically enhance the viral replication and pathogenicity of influenza B virus.

Influenza B viruses (IBVs), though often overshadowed by influenza A viruses (IAVs), remain a significant global public health concern, particularly during seasons when they predominate. However, the molecular mechanisms underlying IBV pathogenicity remain largely unknown. In this study, we identified two amino acid substitutions, PB2-N460S and NP-I163T, from IBV clinical isolates with distinct replication and pathogenicity profiles.

Six Cases of Borealpox and Evidence of a Zoonotic Source-Alaska, 2020-2023.

Section of Epidemiology, Alaska Division of Public Health, Anchorage, Alaska, USA.

Background: Borealpox virus (previously known as Alaskapox virus) is an Orthopoxvirus species first identified in a patient living near Fairbanks, Alaska, in 2015; the source of the patient's infection was unknown. Six additional borealpox cases have been identified through 2023.

Methods: We conducted interviews to ascertain travel history and potential exposures for the six patients, trapped small mammals for orthopoxvirus testing, and performed a phylogenetic analysis of viral DNA sequences.
