TLDR
Comparatively little is known of the life of Jean Leonard Marie Poiseuille but he did establish, in a series of meticulously executed experiments, that at a given temperature water flow through tubes of very fine bore is inversely proportional to the length of the tube and directly proportional toThe pressure gradient and to the fourth power of thetube diameter.Abstract:
Comparatively little is known of the life of Jean Leonard Marie Poiseuille (1797-1869) of Paris. He made important contributions to the experimental study of circulatory dynamics but it can hardly be said that Poiseuille knowingly described the law which governs laminar flow. He did however establish, in a series of meticulously executed experiments, that at a given temperature water flow through tubes of very fine bore is inversely proportional to the length of the tube and directly proportional to the pressure gradient and to the fourth power of the tube diameter.read more

Juan Ignacio Valle,Harpreet Wasan,Daniel H. Palmer,David Cunningham,Alan Anthoney,Anthony Maraveyas,Srinivasan Madhusudan,Timothy Iveson,Sharon M. Hughes,Stephen P. Pereira,M Roughton,John Bridgewater +11 more
TL;DR: Cisplatin plus gemcitabine is an appropriate option for the treatment of patients with advanced biliary cancer and was associated with a significant survival advantage without the addition of substantial toxicity.

Cerebral hemodynamics and vascular risk factors: setting the stage for Alzheimer's disease.
TL;DR: Keeping cerebral hemodynamic homeostasis by careful management of vascular risk factors could be a decisive therapeutic target in the prevention of AD.

Pressure matters: intrarenal pressures during normal and pathological conditions, and impact of increased values to renal physiology
TL;DR: IRP increase remains a neglected predictor of upper tract endourology complications and its intraoperative monitoring should be taken into consideration.

Pathogenesis of the Limb Manifestations and Exercise Limitations in Peripheral Artery Disease
TL;DR: Evaluated mechanisms include a cascade of pathophysiological responses during exercise-induced ischemia and reperfusion at rest that are associated with endothelial dysfunction, oxidant stress, inflammation, and muscle metabolic abnormalities that provide opportunities for targeted therapeutic interventions to address the complex pathophysiology of the exercise impairment in peripheral artery disease.

Jean Leonard Marie Poiseuille
TL;DR: Poiseuille, born and died in Paris, appears to have passed his entire life as unattached (libre) professor of medical physics as discussed by the authors, who was the son of a carpenter.
