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.

BidCorpus: A multifaceted learning dataset for public procurement.

Digital transformation has significantly impacted public procurement, improving operational efficiency, transparency, and competition. This transformation has allowed the automation of data analysis and oversight in public administration. Public procurement involves various stages and generates a multitude of documents.

High percentage of immune Th1 and Tc1 cells infiltrating visceral adipose tissue in people with obesity.

Subcutaneous (SAT) and visceral (VAT) adipose tissue dysfunction during the obesity onset can lead to increased expression of inflammatory molecules, and consequently to immune cell infiltration. The aim was to deeply characterize the T cells, those infiltrating SAT and VAT, compared to peripheral blood (PB), in individuals undergoing bariatric surgery. Forty-two adult individuals were recruited, SAT and VAT samples were collected.

Paclitaxel-Coated Balloon for the Management of In-Stent Coronary Restenosis: An Updated Meta-Analysis and Trial Sequential Analysis.

Background: Drug-coated balloons present a potentially advantageous therapeutic approach for managing coronary in-stent restenosis (ISR). However, the comparative benefits of paclitaxel-coated balloons (PCBs) over uncoated balloons (UCBs) remain unclear.

Aims: We conducted a systematic review and meta-analysis to evaluate and compare the clinical outcomes of patients treated with PCBs and UCBs.

Venom from Spiders Collected in Southeastern and Northeastern Brazilian Regions Cause Hemotoxic Effects on Human Blood Components.

Spiders of the genus represent a public health problem in Brazil due to the severity of the cutaneous and systemic effects that may result from their bite. In the systemic form of loxoscelism, hemolytic anemia, thrombocytopenia, and disseminated intravascular coagulation can occur. Despite the seriousness of accidents, the venom of some species has not yet been properly characterized considering these hemotoxic effects, such as that of , , and .
