Cardio-Obstetrics Practice in Latin America: A Regional Survey of General Cardiologists.

Background: Cardiovascular (CV) disease is a leading cause of death in pregnant women globally, especially in low- and middle-income countries including Latin America (LATAM), where there is lack of data on how cardiologists are trained in cardio-obstetrics (CO) and the practice patterns in the care of pregnant patients.

Objectives: The authors aimed to identify CO competency and practice patterns among LATAM general cardiologists.

Methods: An anonymous cross-sectional Google-based electronic survey was sent via email to clinical cardiologists through local American College of Cardiology chapters and CV societies.

Impact of gold nanoparticle size and coating on radiosensitization and generation of reactive oxygen species in cancer therapy.

Radiation therapy is a common cancer treatment but often damages surrounding healthy tissues, leading to unwanted side effects. Despite technological advancements aimed at improving targeting, minimizing exposure to normal cells remains a major challenge. High-Z nanoparticles, such as gold nanoparticles (AuNPs), are being explored as nano-radiosensitizers to enhance cancer treatment through physical, biological, and chemical mechanisms.

Hybridization and Introgression in Black Hakes (Merluccius polli and M. senegalensis): Evolutionary Dynamics and Conservation Implications in the Contact Zone Exploited by Multi-Species Fisheries.

Hybridization is relatively common between closely related species that share part of their distribution. Understanding its dynamics is important both for conservation purposes and to determine its role as an evolutionary mechanism. Here we have studied the case of black hakes (Merluccius polli and Merluccius senegalensis) in its contact zone.

CRISPR/Cas9 screens identify LIG1 as a sensitizer of PARP inhibitors in castration-resistant prostate cancer.

PARP inhibitors (PARPi) have received regulatory approval for the treatment of several tumors, including prostate cancer (PCa), and demonstrate remarkable results in the treatment of castration-resistant prostate cancer (CRPC) patients characterized by defects in homologous recombination repair (HRR) genes. Preclinical studies showed that DNA repair genes (DRG) other than HRR genes may have therapeutic value in the context of PARPi. To this end, we performed multiple CRISPR/Cas9 screens in PCa cell lines using a custom sgRNA library targeting DRG combined with PARPi treatment.

Genetic diversity of dengue virus circulating in the Philippines (2014-2019) and comparison with dengue vaccine strains.

Dengue virus has four distinct serotypes and the genetic diversity within each of the four serotypes contribute to its complexity. An important aspect of dengue molecular evolutionary studies has been the dissection of the extent and structure of genetic variation among major genotypes within each serotype. It is important to understand the role of dengue genetic variability and its potential role and impact in the effectiveness of the dengue vaccine.
