Toward a phylogenomic classification of magnoliids.

Premise: Magnoliids are a strongly supported clade of angiosperms. Previous phylogenetic studies based primarily on analyses of a limited number of mostly plastid markers have led to the current classification of magnoliids into four orders and 18 families. However, uncertainty remains regarding the placement of several families.

Horizontal transposon transfer (HTT) plays an important role in the evolution of eukaryotic genomes; however, the detailed evolutionary history and impact of most HTT events remain to be elucidated. To better understand the process of HTT in closely related microbial eukaryotes, we studied Ty4 retrotransposon subfamily content and sequence evolution across the genus Saccharomyces using short- and long-read whole genome sequence data, including new PacBio genome assemblies for two Saccharomyces mikatae strains. We find evidence for multiple independent HTT events introducing the Tsu4 subfamily into specific lineages of Saccharomyces paradoxus, Saccharomyces cerevisiae, Saccharomyces eubayanus, Saccharomyces kudriavzevii and the ancestor of the S.

Psychodinae (Diptera: Psychodidae), commonly known as "drain flies", are a subfamily of insects adapted to environments modified by humans. While often regarded as harmless, it has been reported that they may carry pathogenic microorganisms, contributing to hospital environmental contamination and potentially playing a role in healthcare-associated infections. This study aimed to investigate drain flies in a hospital setting to assess their role in carrying microbial pathogens.

Introduction: Anandamide (AEA) is an endocannabinoid that has recently been recognized as a regulator of various inflammatory diseases as well as cancer. While AEA was thought to predominantly engage cannabinoid (CB) receptors, recent findings suggest that, given its protective anti-inflammatory role in pathological conditions, anandamide may engage not only CB receptors.
Methods: In this study, we studied the role of exogenous AEA in a mouse AirPouch model of acute inflammation by examining immune cell infiltrates by flow cytometry.

Midbrain dopamine (mDA) neurons participate in a wide range of brain functions through an intricate regulation of DA biosynthesis. The epigenetic factors and mechanisms in this process are not well understood. Here we report that histone demethylase JMJD3 is a critical regulator for DA biosynthesis in adult mouse mDA neurons.
