Larger First-Trimester Placental Volumetric Parameters Are Associated With Lower Pressure and More Flow-Mediated Vasodilation of the Fetoplacental Vasculature After Delivery

Frontiers in Physiology, 2020
ObjectiveTo explore the correlation between in vivo placental volumetric parameters in the first trimester of pregnancy and ex vivo parameters of fetoplacental vascular function after delivery.MethodsIn ten singleton physiological pregnancies, placental ...

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.

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 ...

Increased Serum Klotho With Age-Related Aortic Stiffness and Peripheral Vascular Resistance in Young and Middle-Aged Swine

Frontiers in Physiology, 2020
The anti-aging function of Klotho gene has been implicated in age-related diseases. The physiological importance of Klotho in the progression of arterial stiffness with aging, however, remains unclear.

Changes in Vascularization of Human Breast Cancer Xenografts Responding to Antiestrogen Therapy

Neoplasia: An International Journal for Oncology Research, 1999
To elucidate the previously suggested vascular effect(s) of antiestrogen therapy, we studied the effect of estrogen withdrawal and tamoxifen on 1) vascular resistance, 2) glucose and oxygen consumption, 3) vascular density in a perfused breast cancer ...

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 ...

Mild Hypobaric Hypoxia Enhances Post-exercise Vascular Responses in Young Male Runners

Frontiers in Physiology, 2019
It has been reported that sustained post-exercise vasodilation may be linked to exercise-induced angiogenesis. The present study aimed to evaluate whether mild hypobaric hypoxia enhances the post-exercise reduction in systemic vascular resistance in ...

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 ...
