- Megaleporinus macrocephalus (piauçu) is a Neotropical fish with a unique ZZ/ZW sex determination system, making it an excellent model to study sex chromosomes.
- Researchers assembled a high-quality reference genome of over 1.28 billion base pairs, revealing distinct regions on the sex chromosome that exhibit degeneration and differentiation.
- Key findings indicate that genes like amhr2 and bmp7 may play important roles in sex determination and provide insights into the evolutionary dynamics of fish sex chromosomes.
Background: As the diagnosis of Pediatric venous thromboembolism has dramatically increased in recent decades, this study aims to evaluate these patients, determining the incidence and describing their biological and clinical characteristics.
Methods: An observational, cross-sectional study was conducted at a Brazilian quaternary hospital between January 2022 and February 2023. Under 18-year-old hospitalized patients with a confirmed diagnosis of venous thromboembolism were included, while those with arterial or chronic thrombosis were excluded.
