A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Endogenous Retrovirus ev21 dose Not Recombine with ALV-J and Induces the Expression of ISGs in the Host

Frontiers in Cellular and Infection Microbiology, 2016
Avian leukosis virus subgroup J (ALV-J) infection can cause tumors and immunosuppression. Endogenous viruses integrate into host genomes and can recombine with exogenous avian leukosis virus (ALV). In this study, we analyzed the interaction of endogenous

Gut microbiota profiles of commercial laying hens infected with tumorigenic viruses

BMC Veterinary Research, 2020
Background Studies have shown that some viral infections cause structural changes in the intestinal microflora, but little is known about the effects of tumorigenic viral infection on the intestinal microflora of chickens.

Shared Waters, Shared Responsibility: Solving Collective Action Problems in an Upstream‐Downstream Setting

Environmental Policy and Governance, EarlyView.
ABSTRACT The governance of shared water systems requires collaboration across diverse stakeholders. In this study we advance the theoretical understanding of asymmetric collective action problems (CAPs) by reassessing the role of third‐party interventions and emphasizing the strategic importance of policy brokers and institutional venues.

Exosomal miR-7-25207 Increases Subgroup J Avian Leukosis Virus Titers by Targeting the Akt-CyclinQ1 and PRC1-YAF2 Dual Pathways

Microorganisms
Subgroup J avian leukosis virus (ALV-J) is a major pathogen in poultry, causing substantial economic losses to the poultry industry worldwide. Exosomal small RNAs derived from virus-infected cells or biological fluids can serve as viral transmission ...

Simulations of Photovoltaic Systems on Different Types of Ships in Sweden: Solar Energy Generation, Comparison to Energy Consumption, and Reduction of CO2 Emission

Energy Science &Engineering, EarlyView.
Investigation of the potential of using solar cells on different types of ships, to see how it reduces energy consumption and emissions of carbon dioxide (CO2). From the reduction in fuel consumption, the fuel cost reduction was estimated, and an approximate payback time for the solar cell system was calculated.

A chicken liver cell line efficiently supports the replication of ALV-J possibly through its high level viral receptor and efficient protein expression system

Veterinary Research, 2018
In this study, we identified a chicken liver cell line (LMH) which could strongly support the replication of ALV-J (Subgroup J of avian leukosis virus) with high viral titer.

Changes in 1‐year relative survival of patients with cancer during the COVID‐19 pandemic in Denmark, Finland, Iceland, Norway, and Sweden: A population‐based cohort study

International Journal of Cancer, EarlyView.
What's New? In the first year of the COVID‐19 pandemic, cancer reporting in the Nordic countries declined, presumably owing to delays in cancer diagnosis. How the pandemic impacted cancer survival in these countries, however, remains unclear. Using data from Nordic cancer registries that together include more than 27 million people, the authors of the ...
