Lispe represents a species-rich genus within the family Muscidae. The current subdivision of Lispe species into species groups is based mainly on adult morphology and ecology, with the only available phylogenetic study based on three molecular markers. Nonetheless, certain species groups remain unclear and the relationships and composition of these groups are still unresolved.

Background: Patients with Fontan circulation are frail and experience multisystem dysfunction including impaired exercise capacity, low resting and exercise-augmented cardiac output, and progressive liver fibrosis. However, common underlying biochemical abnormalities or disease-specific biomarkers have not been well-described.

Objectives: We wish to investigate Fontan and their matched healthy subjects using a nontargeted, followed by targeted metabolomic analysis.

The discovery that extracellular RNAs (exRNA) can act as endocrine signalling molecules established a novel paradigm in intercellular communication. ExRNAs can be transported, both locally and systemically in virtually all body fluids. In association with an array of carrier vehicles of varying complexity, exRNA can alter target cell phenotype.

Article Synopsis
  • - Blowflies are a diverse group with limited genomic information available, as only 16 species have publicly accessible genome assemblies, despite there being many more species known.
  • - The current genetic databases show significant gaps, with only about 16.5% of blowfly species represented in DNA barcodes, approximately 3% in mitogenomes, and less than 1% in complete genomes.
  • - The review emphasizes the need for more comprehensive genomic research across various blowfly subfamilies to improve studies related to their identification, evolution, and systematics.

Background: Dyslipidaemia in patients with diabetes contributes to the risk of atherosclerotic cardiovascular disease. We aimed to identify a dyslipidemic profile associated with both dysglycemia and subclinical coronary atherosclerosis.

Methods: Study participants (n = 5050) were classified in three groups: normoglycemia, pre-diabetes, and diabetes.
