Measuring the Interaction Between the Macro- and Micro-Vasculature

Frontiers in Cardiovascular Medicine, 2019
Structural and functional dysfunction in both the macro- and microvasculature are a feature of essential hypertension. In a healthy cardiovascular system, the elastic properties of the large arteries ensure that pulsations in pressure and flow generated ...

Milrinone acts as a vasodilator but not an inotrope in children after cardiac surgery - Insights from wave intensity analysis [PDF]

, 2020
Objectives: Milrinone is an inodilator widely used in the postoperative management of children undergoing cardiac surgery. The literature supporting its inotropic effect is sparse.

Comparison of arterial waves derived by classical wave separation and wave intensity analysis in a model of aortic coarctation [PDF]

Medical & Biological Engineering & Computing, 2008
Coarctation of the aorta may develop during fetal life and impair quality of life in the adult because upper body hypertension and aneurysm formation in the descending aorta may develop. We used our computational model of the young adult arterial circulation, incorporated aorta coarctation over a range from 0 to 80% and evaluated the effects in terms ...

Altered cardiac‐coronary coupling relates to abnormal fractional flow reserve without flow limitation after percutaneous coronary interventions

Physiological Reports
A significant proportion of stenoses have an abnormal fractional flow reserve (FFR) after angiographically successful percutaneous coronary intervention (PCI), which is traditionally attributed to differences in coronary flow velocity reserve (CFVR) or ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Wave Intensity Analysis and Central Blood Pressure [PDF]

Hypertension, 2009
In this issue of Hypertension , Manisty and colleagues1 provide, using wave intensity analysis (WIA), new insight into hemodynamic mechanisms of blood flow and energy transfer in conduit arteries which are relevant to the basic pathophysiology of cardiovascular disease.

Intense and Mild Wave of COVID-19 in The Gambia: a Cohort Analysis [PDF]

SSRN Electronic Journal, 2020
ABSTRACT Background The SARS-CoV-2 pandemic is evolving differently in Africa compared to other regions, with lower transmission and milder clinical presentation. Reasons for this are not fully understood.

Analysis of gravity-waves produced by intense tropical cyclones [PDF]

Annales Geophysicae, 2010
Abstract. Conventional and wavelet methods are combined to characterize gravity-waves (GWs) produced by two intense tropical cyclones (TCs) in the upper troposphere and lower stratosphere (UT/LS) from GPS winsonde data. Analyses reveal large contribution of GWs induced by TCs to wave energy densities in the UT/LS. An increase in total energy density of

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

A non-invasive clinical application of wave intensity analysis based on ultrahigh temporal resolution phase-contrast cardiovascular magnetic resonance

Journal of Cardiovascular Magnetic Resonance, 2012
Background Wave intensity analysis, traditionally derived from pressure and velocity data, can be formulated using velocity and area. Flow-velocity and area can both be derived from high-resolution phase-contrast cardiovascular magnetic resonance (PC-CMR)
