Thermally Activated Delayed Fluorescence in B,N-Substituted Tetracene Derivatives: A Theoretical Pathway to Enhanced OLED Materials.

Polycyclic aromatic hydrocarbons (PAHs) exhibit intriguing characteristics that position them as promising candidates for advancements in organic semiconductor technologies. Notably, tetracene finds substantial utility in Electronics due to its application in organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). The strategic introduction of an isoelectronic boron-nitrogen (B,N) pair to replace a carbon-carbon pair in acenes introduces changes in the electronic structure, allowing for the controlled modulation of diradical characteristics.

Spontaneous Tumor Lysis Syndrome in a Thoracic Burkitt Lymphoma: A Case Report.

Burkitt lymphoma has a high proliferation rate and a significant risk of tumor lysis syndrome. Risk stratification and early identification are imperative since it is an oncological emergency. We report the case of a 20-year-old woman, without relevant past medical history, admitted to the Emergency Department with a three-week history of fatigue, chest discomfort, productive cough, night sweats, myalgia, odynophagia, and holocranial headache.

Mortality from Hypertrophic Cardiomyopathy in Brazil-Historical Series.

Hypertrophic cardiomyopathy (HCM) is a relatively prevalent disease, primarily of a genetic etiology, affecting both sexes and characterized by left ventricular hypertrophy. However, limitations within healthcare systems, socioracial factors, and the issue of underdiagnosis hinder accurate mortality assessments in our region. This study, therefore, aimed to assess the mortality trends associated with HCM in Brazil from 2010 to 2020, with a focus on socioracial factors and healthcare disparities.

Association between total, regional and organ fat and type 2 diabetes risk factors among Latino youth: A longitudinal study.

Introduction: To examine whether within-person changes in total, regional and organ fat were associated with within-person changes in type 2 diabetes (T2D)-related biomarkers following interventions.

Methods: A secondary analysis from a randomised trial among Latino youth (30 males, 25 females) aged 12-16 years with obesity. The study sample combined participants randomised to either lifestyle intervention (N = 39) or usual care (N = 16).

Autophagy and cancer therapy.

Autophagy is an intracellular degradation process that sequesters cytoplasmic components in double-membrane vesicles known as autophagosomes, which are degraded upon fusion with lysosomes. This pathway maintains the integrity of proteins and organelles while providing energy and nutrients to cells, particularly under nutrient deprivation. Deregulation of autophagy can cause genomic instability, low protein quality, and DNA damage, all of which can contribute to cancer.
