Article Abstract
is a phytophagous insect widely distributed across Asia, Europe, and Africa, yet its genetic variation remains poorly understood. This study presents the first comprehensive analysis of the genetic diversity and structure of in Thailand using mitochondrial cytochrome c oxidase subunit 1 () sequences from 202 individuals across 27 localities. A total of 58 haplotypes were identified, with high haplotype and nucleotide diversity observed, suggesting substantial genetic variation. The haplotype network revealed a star-like topology, indicating recent population expansion or ongoing gene flow. Neutrality tests and mismatch distribution analyses showed no strong signal of recent demographic expansion. Phylogenetic analysis confirmed that all Thai specimens clustered within a well-supported clade along with sequences from India, Namibia, and Europe. Analysis of Molecular Variance (AMOVA) revealed significant genetic differentiation among four continental groups, indicating that geographic isolation and restricted gene flow have shaped genetic divergence at a broad biogeographic scale. Further research using highly polymorphic nuclear markers is recommended to better resolve the population structure and evolutionary history of in Thailand and beyond.

The emergence of organoid models has significantly bridged the gap between traditional cell cultures/animal models and authentic human disease states, particularly for genetic disorders, where their inherent genetic fidelity enables more biologically relevant research directions and enhances translational validity. This review systematically analyzes established organoid models of genetic diseases across organs (e.g.

Pharmacological modulation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) through dual GIP/GLP-1 receptor agonists, commonly used for diabetes and obesity, shows promise in reducing alcohol consumption. We applied drug-target Mendelian randomization (MR) using genetic variation at these loci to assess their long-term effects on problematic alcohol use (PAU), binge drinking, alcohol misuse classifications, liver health, and other substance use behaviors. Genetic proxies for lowered BMI, modeling the appetite-suppressing and weight-reducing effects of variants in both the GIPR and GLP1R loci ("GIPR/GLP1R"), were linked with reduced binge drinking in the primary (β = -0.

To breed for climate resilient crops, an understanding of the genetic and environmental factors influencing adaptation is critical. Barley provides a model species to study adaptation to climate change. Here we present a detailed analysis of genetic variation at a major photoperiod response locus and relate this to the domestication history and dispersal of barley.

Purpose: Polymorphous adenocarcinoma of the salivary gland is characterized by cellular uniformity associated with a variety of morphological growth patterns, a fact that makes its diagnosis challenging. Therefore, the identification of genetic alterations and signaling pathways emerges as a tool for elucidation of the pathogenesis of this tumor and accurate differential diagnosis. The aim of this study was to assess mutations in the PRKD1 gene and in protein components of the HH pathway (SHH, IHH, SMO, and GLI-1) in cases of polymorphous adenocarcinoma of the salivary gland.

T-cell receptors (TCRs) recognize antigens derived from fragments of somatically expressed proteins that are degraded by the proteasome and presented by specific human leukocyte antigen (HLA) molecules. Recent therapeutic advances using the TCR as a tumor-targeting moiety have focused attention on loss of heterozygosity (LOH) as a potential resistance mechanism. Allele-specific LOH, rather than allele-agnostic, is particularly pertinent, but rarely evaluated.
