Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Associations between intake of vitamins E and A and serum concentrations in preterm infants: A retrospective cohort study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Infants in neonatal intensive care are at risk of both deficiency and excess of fat‐soluble vitamins, particularly E and A, due to limited reserves and the need for prolonged intravenous nutrition. We aimed to determine the effects of increased intravenous vitamin intake and to characterise the relationships between vitamin intake ...

Gymnema sylvestre: Bioactive constituents, health benefits, and emerging applications in nutraceuticals and functional foods

JSFA reports, EarlyView.
Abstract Gymnema sylvestre (Retz.) R.Br. ex‐Schult., commonly known as “gurmar” or “sugar destroyer,” belongs to the Apocynaceae family and is traditionally used in Ayurveda for diabetes management. This review synthesizes ethnomedicinal evidence with contemporary pharmacological studies, to evaluate the therapeutic properties and mechanistic actions ...

Heterogeneity Analyzed by CT‐Based Habitat Analysis for Clinical Management of Cancers: A Narrative Review

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Tumors are highly heterogeneous, and whole‐lesion radiomics analysis is a popular method for extracting texture features that reflect this heterogeneity, which can be used to build models for cancer diagnosis, staging, therapy response evaluation, and prognosis prediction.

Adrenomedullin in the cerebral circulation

Peptides, 2001
The central nervous system requires an effective autoregulation of cerebral circulation in order to meet the critical and unusual demands of the brain. In addition, cerebral microvessels has a unique feature, the formation of the blood-brain barrier, which contributes to the stability of the brain parenchymal microenvironment. Many factors are known to

Rheology of the Cerebral Circulation

Neurosurgery, 1984
Current concepts of brain perfusion focus on the importance of rheological factors in the determination of cerebral blood flow. Blood viscosity, a primary determinant of blood flow, increases as the shear rate (velocity gradient) decreases, thereby impeding cerebral perfusion.

The Control of the Cerebral Circulation

JAMA, 1961
The cerebral circulation is broadly limited by factors extrinsic to the brain, namely the general arterial blood pressure and the cardiac output. The cerebral blood flow will be maintained until the cardiac output is decreased by more than a third or the blood pressure is lowered to half or less of the normal value.

Cerebral circulation in aging

Ageing Research Reviews, 2016
Cerebral circulation is known to be protected by the regulatory function against the hypoperfusion that will affect the cognitive function as a result of brain ischemia and energy failure. The regulatory function includes cerebrovascular autoregulation, chemical control, metabolic control, and neurogenic control, and those compensatory mechanisms can ...

Cerebral Circulation and Resuscitation

Acta Anaesthesiologica Scandinavica, 1968
SUMMARYAfter reviewing the literature mainly with a view to elucidate the effect of drugs commonly used in cardiac resuscitation on CBF, attention is drawn to the frequent occurrence of obstruction or stenosis in the extracranial cerebral vessels.

Regulation of the Cerebral Circulation

Annual Review of Physiology, 1981
This aspect of the regulation of the cerebral circulation has been under intensive investigation for the past several years. Many uncertainties have been clarified, but a satisfying answer to the important question of what role neurogenic influences play in the physiological regulation of cerebral blood flow (CBF) remains elusive.
