Population Phylogenomics and Genetic Structure of the Polyphagous Leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae)

open access: yesEvolutionary Applications, Volume 18, Issue 7, July 2025.
ABSTRACT The agromyzid leafminer Liriomyza trifolii (Burgess) is an important polyphagous pest of vegetable crops and ornamental plants. It is native to the Americas but has spread throughout the world over the past 50 years. Previous molecular research has indicated that this species contains highly distinct mitochondrial lineages suggestive of ...

Thyroid Hormone Dynamics and DIO2 Variants in Schizophrenia: Exploring Genetic Links to Neuroendocrine Imbalance

open access: yesJournal of Cellular and Molecular Medicine, Volume 29, Issue 13, July 2025.
ABSTRACT Thyroid hormone modulates multiple neurotransmitter systems, including dopaminergic, serotonergic, glutamatergic and GABAergic pathways, which are implicated in schizophrenia (SCH) pathophysiology. The Type II deiodinase (DIO2) enzyme plays a critical role in thyroid metabolism, converting thyroxine (T4) into the biologically active ...

Multivariate Effects of SNPs on Environmental Streptococcal Mastitis Evaluated With an NGS‐Based Association Study Using Targeted Resequencing in the Bovine MHC Region

open access: yesHLA, Volume 106, Issue 1, July 2025.
ABSTRACT Mastitis is an inflammatory reaction caused by bacterial infection of the teat, and a relationship between its onset and cattle major histocompatibility complex (BoLA) region has been reported. However, no comprehensive genetic analysis of mastitis caused by environmental streptococci has been reported.
