Dynamic conditioning of porcine kidney grafts with extracellular vesicles derived from urine progenitor cells: A proof-of-concept study.

 : Among strategies to limit ischemia/reperfusion (IR) injuries in transplantation, cell therapy using stem cells to condition/repair transplanted organs appears promising. We hypothesized that using a cell therapy based on extracellular vesicles (EVs) derived from urine progenitor cells (UPCs) during hypothermic and normothermic machine perfusion can prevent IR-related kidney damage. We isolated and characterized porcine UPCs and their extracellular vesicles (EVs).

[Organ conservation and transportation modalities].

ORGAN CONSERVATION AND TRANSPORTATION MODALITIES. Organ preservation in transplantation is an essential step in the graft journey between the donor and the recipient. The modalities of preservation have become a major element in this process given the evolution of donors in terms of age and associated comorbidities.

Analysis of Pre-clerkship Medical Students' Perceptions and Performance During the COVID-19 Pandemic.

Purpose: Virtual instruction became the primary educational delivery method for pre-clerkship medical students during the COVID-19 pandemic. The aims of this study were to evaluate the effectiveness of a virtual and blended pre-clerkship curriculum and to assess its impact on students.

Methods: We surveyed 223 1st- and 2nd-year medical students (MS1s and MS2s) enrolled at the Paul L Foster School of Medicine.

Perinatal Administration of C-Phycocyanin Protects Against Atherosclerosis in apoE-Deficient Mice by Modulating Cholesterol and Trimethylamine-N-Oxide Metabolisms.

Objective: Gestational hypercholesterolemia concomitantly with a highly oxidative environment is associated with higher atherosclerosis in human and animal offspring. This work aimed to determine whether perinatal administration of a C-phycocyanin concentrate, a powerful antioxidant, can protect against atherosclerosis development in genetically hypercholesterolemic mice in adult life. Approach and Results: C-Phycocyanin was administered during gestation solely or gestation and lactation to apolipoprotein E-deficient mice.
