Porcine kidney xenotransplantation: From primate models to clinical reality
Animal Models and Experimental Medicine, EarlyView.In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Waves in arteries: A review of wave intensity analysis in the systemic and coronary circulations
Artery Research, 2008 The intermittent ejection of blood by the ventricle results in pulsatile pressure and flow waveforms in the circulation. Understanding and characterizing this pulsatile behaviour is attracting increasing clinical interest, as it may have important ...

Effect of waveform on turbulence transition in pulsatile pipe flow
Pulsatile flow in a straight pipe is a model system for unsteady internal flows in industrial engineering and physiology. In some parameter regimes, the laminar flow is susceptible to helical perturbations, whose transient energy growth scales ...

Idiopathic Intracranial Hypertension Is Characterized by a Distinct Proteomic Profile
Annals of Neurology, EarlyView.Objectives The pathophysiology of idiopathic intracranial hypertension (IIH) is poorly understood and disease‐specific biomarkers are lacking. We aimed to shed light on IIH pathophysiology and identify disease‐specific biomarkers. Methods This prospective cross‐sectional cohort study included patients with new‐onset IIH and age‐, body mass index‐, and ...

The Anatomical Record, EarlyView.This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

An Interactive Data Acquisition and Control System Coupled on a Pulsatile Pipe Flow Test Rig
Measurement + Control, 2002 A test rig to be used for time-dependent static pressure and velocity distribution measurements in a pulsatile pipe flow with laminar, transitional and turbulent regimes was initially designed and constructed.

Turbulent puffs in transitional pulsatile pipe flow at moderate pulsation amplitudes
We show that, in the transitional regime of pulsatile pipe flow, at moderate-to-high amplitudes 0.5≲≲1, the first long-lived turbulent structures are localized and take the form of the puffs and slugs observed in statistically steady pipe flow.
