Valorization of platelets with no therapeutic value with Pulsed Electric Fields

Platelets are blood components with high biomedical potential due to their physiological role in wound healing and their rich growth factor content. This paper describes proof of concept experiments aimed to produce a new blood derived product by applying Pulsed Electric Fields (PEF) in platelet concentrates with no therapeutic value for transfusion medicine. A human platelet concentrate suspension was subjecte...

Arterio-arterial graft – an option for hemodialysis patients with exhaustion of...

Introduction: Vascular access (VA) for hemodialysis (HD) is the lifeline for End Stage Renal Disease (ESRD) patients. Long-term HD patients often have exhaustion of their venous patrimony for an autologous VA construction and, sometimes, even for a central venous catheter (CVC) placement. Case report: We describe the case of a 43-year-old woman with ESRD due to lupus nephritis, on maintenance HD since 2009. She...

Endovascular Treatment of Internal Iliac Artery Aneurysms: Single Center Experi...

Objective: Internal iliac artery aneurysms (IIAA) are rare, representing only 0.3% of aortoiliac aneurysms. Its treatment with open surgery is complex and associated with high morbidity and mortality, which led to increasing application of endovascular solutions. In this study, we aimed to evaluate outcomes of endovascular aneurysm repair (EVAR) of IIAA in one institution. Methods: We retrospectively reviewed a...

Endovascular Treatment of Isolated Chronic Abdominal Aortic Dissection

Isolated acute abdominal aortic dissection is a relatively rare event. Its natural history is not fully understood and its optimal treatment is not established. Open surgery represents the most described treatment but endovascular intervention has had increasing application. Isolated chronic abdominal aortic dissection is even less described in the literature. We describe three patients with isolated chronic ab...

Control of predators in industrial scale microalgae cultures with Pulsed Electr...

This work describes the utilization of Pulsed Electric Fields to control the protozoan contamination of a microalgae culture, in an industrial 2.7m3 microalgae photobioreactor. The contaminated culture was treated with Pulsed Electric Fields, PEF, for 6h with an average of 900V/cm, 65μs pulses of 50Hz. Working with recirculation, all the culture was uniformly exposed to the PEF throughout the assay. The develop...
