Long lasting argon neuroprotection in a non-human primate model of transient endovascular ischemic stroke.

In the past decade, noble gases have emerged as highly promising neuroprotective agents. Previous studies have demonstrated the efficacy of argon neuroprotection in rodent models of cerebral ischemia. The objective of the present pre-clinical study was to confirm the neuroprotective effect of argon in a non-human primate model of endovascular ischemic stroke.

Comparing Different Methods for the Diagnosis of Liver Steatosis: What Are the Best Diagnostic Tools?

Background: Due to the ongoing organ shortage, marginal grafts with steatosis are more frequently used in liver transplantation, leading to higher occurrences of graft dysfunction. A histological analysis is the gold standard for the quantification of liver steatosis (LS), but has its drawbacks: it is an invasive method that varies from one pathologist to another and is not available in every hospital at the time of organ procurement. This study aimed to compare non-invasive diagnostic tools to a histological analysis for the quantification of liver steatosis.

In Vivo Feasibility of Arterial Embolization with a New Permanent Agar-agar-Based Agent.

Purpose: Evaluate the safety and efficacy of an eco-friendly permanent agar-agar-based embolization agent (ABEA) (EmboBio®) for intra-arterial use.

Materials And Methods: Six pigs embolized with one ABEA torpedo (6 lower polar renal and 6 lumbar arteries) and one coil (6 lower polar renal and 6 lumbar arteries). Technical success was defined as a complete occlusion with no residual flow in DSA.

Predicting primate tongue morphology based on geometrical skull matching. A first step towards an application on fossil hominins.

As part of a long-term research project aiming at generating a biomechanical model of a fossil human tongue from a carefully designed 3D Finite Element mesh of a living human tongue, we present a computer-based method that optimally registers 3D CT images of the head and neck of the living human into similar images of another primate. We quantitatively evaluate the method on a baboon. The method generates a geometric deformation field which is used to build up a 3D Finite Element mesh of the baboon tongue.
