α1D-Adrenoceptors are responsible for the high sensitivity and the slow time-course of noradrenaline-mediated contraction in conductance arteries [PDF]

, 2013
The objective of this study was to determine whether the different time-course characteristics of α1-adrenoceptor-mediated contraction in arteries can be related to the subtypes involved.

Aorta Segmentation from 3D CT in MICCAI SEG.A. 2023 Challenge [PDF]

arXiv, 2023
Aorta provides the main blood supply of the body. Screening of aorta with imaging helps for early aortic disease detection and monitoring. In this work, we describe our solution to the Segmentation of the Aorta (SEG.A.231) from 3D CT challenge. We use automated segmentation method Auto3DSeg available in MONAI.

Beat Pressure and Comparing it with Ascending Aorta Pressure in Normal and Abnormal Conditions [PDF]

4th European Conference of the International Federation for Medical and Biological Engineering, pp. 276-285. Springer Berlin Heidelberg, 2009, 2014
Lumped method (Electrical analogy) is a quick and easy way to model human cardiovascular system. In this paper Lumped method is used for simulating a complete model. It describes a 36-vessel model and cardiac system of human body with details that could show hydrodynamic parameters of cardiovascular system.
