The Link Between Venous and Arterial Thrombosis: Is There a Role for Endothelial Dysfunction?

Venous thromboembolism (VTE) and arterial thrombosis (AT) are distinct yet closely related pathological processes. While traditionally considered separate entities, accumulating evidence suggests that they share common risk factors, such as inflammation and endothelial dysfunction (ED). This review explores the parallels and differences between venous and arterial thrombosis, with particular attention to the role of unprovoked VTE and its potential links to atherosclerosis and systemic inflammation.

Time to initiation of dialysis and length of stay in hospitalized patients with kidney damage: a cross-sectional study.

Background: Universal healthcare is a cornerstone of Brazil's public health system. However, delayed diagnosis and treatment of chronic kidney disease (CKD) remain substantial issues. The scarcity of outpatient dialysis facilities contributes to extended hospital stays.

A proof-of-concept study in small and large animal models for coupling liver normothermic machine perfusion with mesenchymal stromal cell bioreactors.

To fully harness mesenchymal-stromal-cells (MSCs)' benefits during Normothermic Machine Perfusion (NMP), we developed an advanced NMP platform coupled with a MSC-bioreactor and investigated its bio-molecular effects and clinical feasibility using rat and porcine models. The study involved three work packages: 1) Development (n = 5): MSC-bioreactors were subjected to 4 h-liverless perfusion; 2) Rat model (n = 10): livers were perfused for 4 h on the MSC-bioreactor-circuit or with the standard platform; 3) Porcine model (n = 6): livers were perfused using a clinical device integrated with a MSC-bioreactor or in its standard setup. MSCs showed intact stem-core properties after liverless-NMP.

Göttingen Minipigs as a Model for Assessing the Impact of Drugs on the Gut and Milk Microbiota-A Preliminary Study.

Background: Early gut microbiota (GM) dysbiosis can affect a child's health and has been linked to the onset of pathologies later in life. Breast milk is recognized as a major driver of the structure and dynamics of an infant's GM. In addition to nutritious and prebiotic compounds, milk contains a microbiota that is shaped by several maternal factors, including gut microorganisms and medications.

Inside-out submitochondrial particles affect the mitochondrial permeability transition pore opening under conditions of mitochondrial dysfunction.

The inside-out submitochondrial particles (IO-SMPs) showed a strong protective effect against mitochondrial permeability transition pore (mPTP) opening in mitochondria isolated from swine hearts 3 h after explantation. The latter condition was used to emulate situation of mitochondrial damage. We identified that the protective effect of IO-SMPs cannot be attributed to a functional modulation of the enzymatic complexes involved in mPTP formation.
