Objective: Several works highlight the role of CsA in the prevention of IRI, but none focus on isolated lungs. Our objective was to evaluate the effects of CsA on IRI on ex vivo reperfused pig lungs.
Methods: Thirty-two pairs of pig lungs were collected and stored for 30 minutes at 4 °C. The study was performed in four groups. First, a control group and then three groups receiving different concentrations of CsA (1, 10, and 30 μM) at two different times: once at the moment of lung procurement and another during the reperfusion procedure. The ex vivo lung preparation was set up using an extracorporeal perfusion circuit. Gas exchange parameters, pulmonary hemodynamics, and biological markers of lung injury were collected for the evaluation.
Results: CsA improved the PaO2 /FiO2 ratio, but it also increased PAP, Pcap, and pulmonary vascular resistances with dose-dependent effects. Lungs treated with high doses of CsA displayed higher capillary-alveolar permeability to proteins, lower AFC capacities, and elevated concentrations of pro-inflammatory cytokines.
Conclusions: These data suggest a possible deleterious imbalance between the beneficial cell properties of CsA in IRI and its hemodynamic effects on microvascularization.

Dynamin-related protein 1 (Drp1) is a mitochondrial fission protein and a viable target for cardioprotection against myocardial ischaemia-reperfusion injury. Here, we reported a novel Drp1 inhibitor (DRP1i1), delivered using a cardiac-targeted nanoparticle drug delivery system, as a more effective approach for achieving acute cardioprotection. DRP1i1 was encapsulated in cubosome nanoparticles with conjugated cardiac-homing peptides (NanoDRP1i1) and the encapsulation efficiency was 99.

Background: Hepatic ischemia/reperfusion (I/R) injury (HIRI) is an intrinsic phenomenon observed in the process of various liver surgeries. Unfortunately, there are currently few options available to prevent HIRI. Accordingly, we aim to explore the role and key downstream effects of B-cell lymphoma 6 (BCL6) in hepatic I/R (HIR).

Chronic pain is a prevalent condition affecting a significant portion of the global population and is known to be associated with an increased risk of cardiovascular diseases. Despite the clinical relevance, the mechanisms underlying the link between chronic pain and myocardial ischemia-reperfusion (MI/R) injury remain poorly understood. This study aimed to investigate the role of the superior cervical ganglion (SCG) in mediating the effects of chronic pain on MI/R injury and to develop a novel therapeutic strategy.

Objective: Recently, the pig liver model perfused ex vivo using a normothermic machine perfusion (NMP) has been proposed as a suitable model to study xenobiotic metabolism and biliary excretion. The aim of our study is to describe the metabolism of NPS such as cathinones (with a focus on 4-Cl-PVP and eutylone) in blood and bile, using a normothermic perfused pig liver model.
Methods: Livers (n = 4) from male large white pigs, 3-4 months of age and weighing approximately 75-80 kg, were harvested and reperfused onto an NMP (LiverAssist®, XVIVO) using autologous whole blood at 38 °C.
