Unraveling the organellar genomic landscape of the therapeutic and entheogenic plant Mimosa tenuiflora: insights into genetic, structural, and evolutionary dynamics.

Mimosa tenuiflora, popularly known as "Jurema-Preta", is a perennial tree or shrub native to the tropical regions of the Americas, particularly among Afro-Brazilian and Indigenous Brazilian communities. Known for producing N,N-Dimethyltryptamine, a psychedelic compound with profound psychological effects, Jurema-Preta has been studied for its therapeutic potential in mental health. This study offers a comprehensive analysis of the plastid (ptDNA) and mitochondrion (mtDNA) genomes of M.

Cavitary Pulmonary Tuberculosis in an Infant.

Tuberculosis (TB) continues to pose a significant health challenge globally and in Portugal. Diagnostic challenges persist, especially in infants, where TB often presents with atypical symptoms. A previously healthy three-month-old male infant from Vila Nova de Famalicão, Portugal, was admitted with cough, rhinorrhea, respiratory distress, and high-grade fever.

New Germline TP53 Variant Detected After Radiotherapy-Induced Angiosarcoma of the Chest Wall in a Previously Treated Breast Cancer Patient: A Case Report and Review of Li-Fraumeni Syndrome and Radiotherapy-Induced Sarcoma.

Li-Fraumeni syndrome (LFS) is one of the most common hereditary cancer predisposition syndromes in Brazil. The high frequency of the syndrome is due to a founding variant (R337H) in the country. LFS is characterized by a wide variety of malignant phenotypes.

New low-dose curcumin derivative with therapeutic potential in Alzheimer's disease: Results from an in vitro and in vivo study in mice.

Curcumin has been proposed as a potential treatment for Alzheimer's disease (AD) due to its ability to inhibit amyloid-β (Aβ) peptide aggregates and to destabilise pre-formed ones. Derivative 27 was synthesized to improve low-dose efficacy in the context of AD. Its anti-inflammatory, antioxidant and anti-amyloidogenic activities were evaluated in chemico, in vitro using AD and neuroinflammation cell models, and in vivo using the double-transgenic APP/PS1 mice.

Perioperative Changes in Serum Transaminases Levels Predicts Long-Term Survival Following Liver Resection of Hepatocellular Carcinoma.

Background: We sought to define whether and how hepatic ischemia/reperfusion (I/R) as manifested by perioperative aspartate aminotransferase (AST) and alanine aminotransaminase (ALT) levels impact long-term outcomes after curative-intent resection of hepatocellular carcinoma (HCC).

Patients And Methods: Intrasplenic injection of HCC cells was used to establish a murine model of HCC recurrence with versus without I/R injury. Patients who underwent curative resection for HCC were identified from a multi-institutional derivative cohort (DC) and separate external validation (VC) cohort.
