Descending Aorta Blood Flow Characteristics before the Development of Necrotizing Enterocolitis in Preterm Neonates [PDF]
Neonatal Medicine, 2018 Purpose To investigate the hemodynamic risk factors for necrotizing enterocolitis (NEC), we analyzed the characteristics of descending aorta (DA) blood flow in preterm neonates, who later developed NEC.

The central role of metabolism in vascular morphogenesis [PDF]
arXiv, 2021 As nutrients travel through microcirculation and are absorbed, their availability continuously decreases. However, a uniform nutrient distribution is critical, as it prevents tissue death in poorly supplied areas. How, then, do vascular networks achieve equi-perfusion?

Anxiety increases the blood pressure response during exercise
Motriz: Revista de Educacao Fisica, 2019 Aim: The hypothesis that higher levels of anxiety promote greater blood pressure (BP) responses during physical exercise is tested. The hypothesis that metaborreflex response is increased in an anxious individual is tested as well. Methods: There were

Acute cardiovascular response after maximal cycling exercise in endurance- and strength-trained men
Journal of Men's Health, 2022 Background: Post-exercise hypotension is an important regulator of ambulatory blood pressure—an independent risk factor for cardiovascular disease. Although post-exercise hypotension may be associated with aerobic exercise capacity in male athletes, it ...

Adhering to a Tai Chi Chuan Exercise Program Improves Vascular Resistance and Cardiac Function
International Journal of Gerontology, 2011 Background: Cardiac function is an important predictor for life expectancy in elderly subjects. Tai Chi Chuan (TCC) is a generalized tolerable exercise for the aged population. The current study evaluated the effects of TCC on the vascular compliance and

Pitfalls in the Assessment of Vascular Resistance [PDF]
Cardiology, 1994 Vascular resistance (R) to flow is calculated as the ratio of perfusion pressure between two points (P1-P2) to flow rate (Q). In high-pressure circuits (e.g., systemic), it is justifiable to use arterial pressure (P1) to represent perfusion pressure. It is not permissible to calculate resistance without measuring Q unless a comparison is being made in ...

Optical flow-based vascular respiratory motion compensation [PDF]
arXiv, 2023 This paper develops a new vascular respiratory motion compensation algorithm, Motion-Related Compensation (MRC), to conduct vascular respiratory motion compensation by extrapolating the correlation between invisible vascular and visible non-vascular. Robot-assisted vascular intervention can significantly reduce the radiation exposure of surgeons.

Generative ODE Modeling with Known Unknowns [PDF]
, 2020 In several crucial applications, domain knowledge is encoded by a system of ordinary differential equations (ODE), often stemming from underlying physical and biological processes. A motivating example is intensive care unit patients: the dynamics of vital physiological functions, such as the cardiovascular system with its associated variables (heart ...

Comparison of Carotid Artery Intima-media Thickness and Resistive Index by Ultrasound and Colour Doppler in Pre-hypertensives and Stage One Hypertensives [PDF]
International Journal of Anatomy Radiology and Surgery, 2019 Introduction: Pre-hypertension and stage one hypertension remains major public health problem in both developed and developing countries. It primarily affects elastic arteries, hence common carotid artery Intima-Media Thickness (IMT) and Resistive ...
