Calculating vascular resistances [PDF]

open access: yesClinical Cardiology, 1997
AbstractVascular resistance calculations often affect decisions regarding therapeutic options encountered by physicians and their patients. However, many of the terms, units, and methods used when calculating vascular resistances are ambiguous. This report attempts to clarify some of these ambiguities and suggests methods for predicting normal vascular

Descending Aorta Blood Flow Characteristics before the Development of Necrotizing Enterocolitis in Preterm Neonates [PDF]

open access: yesNeonatal 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

open access: yesJournal 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 ...

Absence of reflex vascular responses from the intrapulmonary circulation in anaesthetised dogs [PDF]

open access: yes, 2000
The aim of this investigation was to determine whether reflex cardiovascular responses were obtained to localised distension of the intrapulmonary arterial and venous circulations in a preparation in which the stimuli to other major reflexogenic areas ...

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

open access: yesFrontiers 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.

Nitric Oxide Bioavailability and Its Potential Relevance to the Variation in Susceptibility to the Renal and Vascular Complications in Patients With Type 2 Diabetes [PDF]

open access: yes, 2009
OBJECTIVE—We compared the renal and systemic vascular (renovascular) response to a reduction of bioavailable nitric oxide (NO) in type 2 diabetic patients without nephropathy and of African and Caucasian heritage.

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

open access: yesNeoplasia: 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 ...

Natriuretic peptides and cardiovascular damage in the metabolic syndrome. Molecular mechanisms and clinical implications [PDF]

open access: yes, 2010
Natriuretic peptides are endogenous antagonists of vasoconstrictor and salt- and water-retaining systems in the body's defence against blood pressure elevation and plasma volume expansion, through direct vasodilator, diuretic and natriuretic properties ...
