Mammary Gland Reactive Stroma Characterization at Aging After Bisphenol A Exposure During Hormonal Susceptibility Windows.

Mammary glands development is influenced by endocrine signaling, which remodels epithelial and stromal compartments. Reactive stroma phenotype is observed when stromal disturbances occur, leading to changes in extracellular matrix composition and occurrence of reactive cell types. One of the triggers of these alterations is endocrine-disrupting chemical exposure, such as bisphenol A (BPA).

Autoantibody clusters in childhood-onset systemic lupus erythematosus: Insights from a multicenter study with 912 patients.

To identify clusters of autoantibodies in a large cSLE population and to verify possible associations between different autoantibody clusters and the following variables: demographic data, cumulative clinical and laboratory manifestations, disease activity, cumulative damage and mortality. A cross-sectional study was performed in 27 Pediatric Rheumatology University centers, including 912 cSLE patients. The frequencies of seven selected autoantibodies (anti-dsDNA, anti-Ro/SSA, anti-La/SSB, anti-Sm, anti-RNP, aCL IgM and/or IgG and LA) were used for cluster analysis using the K-means method.

Assessing diapocynin's different effects on osteosarcoma and breast cancer cells: An in vitro study.

Osteosarcoma is the most common primary bone cancer, accounting for approximately 5 % of new cancer cases globally. In contrast, breast cancer remains the most prevalent malignancy and a leading cause of cancer-related mortality among women. Given the limitations of current therapies, novel treatment strategies are urgently needed.

Cashew nut consumption reduces waist circumference and oxidative stress in adolescents with obesity: A randomized clinical trial.

Previous evidence suggests that certain types of nuts, when included in a healthy diet pattern, may provide health benefits. Therefore, we hypothesize that the consumption of cashew nuts associated with a healthy diet may enhance antioxidant defenses and improve anthropometric and body composition parameters in individuals with obesity. We conducted a 12-week randomized clinical trial, divided into 4 sessions, involving adolescents randomly assigned to receive either 30 g of roasted cashew nuts together with nutrition education (cashew nut group-CNG) or only nutrition education (control group-CG).

Selective phosphodiesterase 4 inhibitor roflumilast reduces inflammation and lung injury in models of betacoronavirus infection in mice.

Objective: We aimed to understand the potential therapeutic and anti-inflammatory effects of the phosphodiesterase-4 (PDE4) inhibitor roflumilast in models of pulmonary infection caused by betacoronaviruses.

Methods: Mice were infected intranasally with murine hepatitis virus (MHV-3) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Roflumilast was given to MHV-3-infected mice therapeutically at doses of 1 mg/kg or 10 mg/kg, or prophylactically at 10 mg/kg.
