Metal complexes are well known for their DNA cleavage activity. Copper is a metal that stands out for this purpose because it is able to perform cleavage through oxidative mechanisms using the Haber–Weiss cycle. We report two unprecedented copper(II) complexes ( 2 and 3 ) with long-chain ligands and compare the results with those of a previously reported complex ( 1 ), which we use as a reference in our studies. They were all...

Medulloblastoma (MB), the most common malignant pediatric brain tumor, is classified into four molecular groups: WNT, SHH, G3, and G4. G3 and G4 MBs are characterized by poor prognosis and high metastatic potential. Although USP2 (ubiquitin-specific peptidase 2) has been described as a prognostic biomarker and a promising therapeutic target in several cancer types, its role in the pathogenesis of G3 and G4 MBs remains unexplor...

Oncogenetics focuses on identifying and managing hereditary cancer predisposition, enabling risk-reducing interventions and targeted therapies. This descriptive study evaluated the landscape of oncogenetics training within Medical Genetics Residency Programs in Brazil. Data were collected through online questionnaires and interviews with program supervisors. We assessed rotation availability, timing and duration, clinical and...

This paper describes the Santos Basin Underwater Soundscape Monitoring Project (PMPAS-BS), a Brazilian ocean soundscape monitoring initiative. The main objective of the project is to quantify and assess hydroacoustic noise of anthropogenic origin in a large sedimentary basin extending from 23° S to 28° S on the southeastern Brazilian continental margin of the South Atlantic Ocean. Noise associated with oil and gas (O&G) explor...
