Early-Stage Luminal B-like Breast Cancer Exhibits a More Immunosuppressive Tumor Microenvironment than Luminal A-like Breast Cancer.

Background: Breast cancer is a heterogeneous malignant disease with a varying prognosis and is classified into four molecular subtypes. It remains one of the most prevalent cancers globally, with the tumor microenvironment playing a critical role in disease progression and patient outcomes.

Methods: This study evaluated tumor samples from 40 female patients with luminal A and B breast cancer, utilizing flow cytometry to phenotypically characterize the immune cells and tumor cells present within the tumor tissue.

Prognostic Implications of Decorin, E-Cadherin and EGFR Expression in Inflammatory and Non-Inflammatory Canine Mammary Carcinomas.

Inflammatory mammary carcinoma (IMC) is the most aggressive variant of invasive mammary tumours in dogs and in women. Decorin is an extracellular matrix molecule whose expression can be reduced or absent in various human cancers, which is associated with a poor prognosis. E-cadherin is a cell adhesion protein whose expression is reduced in several neoplasms.

Electrochemical Biosensors 3D Printed by Fused Deposition Modeling: Actualities, Trends, and Challenges.

The technology of 3D printing, particularly fused deposition modeling (FDM) 3D printing, has revolutionized the development of electrochemical biosensors, offering a versatile and cost-effective approach for clinical applications. This review explores the integration of FDM in fabricating biosensing platforms tailored for clinical diagnostics, emphasizing its role in detecting various biomarkers and viral pathogens. Advances in 3D printing materials, especially the emergence of bespoke conductive filaments, have allowed the production of highly customizable and efficient biosensors.

Sex-specific association between maternal childhood adversities and offspring's weight gain in a Brazilian cohort.

Maternal adverse childhood experiences (ACEs) are linked to negative health and developmental outcomes in offspring. However, whether maternal ACEs influence infant weight gain in the first months of life, and if this effect differs by infant sex, remains unclear. This study included 352 full-term newborns from low-risk pregnancies and their mothers in low-income settings in Brazil.
