Increased Pulse Wave Velocity in Subclinical Hypothyroidism [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2006
Subclinical hypothyroidism affects 5-15% of the general population and is associated with increased morbidity from cardiovascular disease. Brachial-ankle pulse wave velocity (baPWV) is a parameter of arterial stiffening and a good independent predictor for the presence of coronary artery disease.

Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Clinical Associations of Vascular Stiffness, Microvascular Dysfunction, and Prevalent Cardiovascular Disease in a Black Cohort: The Jackson Heart Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Measures of vascular dysfunction are related to adverse cardiovascular disease (CVD) outcomes in non‐Hispanic, White populations; however, data from Black individuals are limited.

A novel drifter designed for use with a mounted Acoustic Doppler Current Profiler in shallow environments [PDF]

, 2013
We present a novel design for a surface drifter, mounted with a pulse-coherent Acoustic Doppler Current Profiler (ADCP) for measuring near-surface (depths 0.18-1 m) flows.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

The study of vascular wall stiffness in patients with arterial hypertension depending on some factors of risk and associated clinical conditions [PDF]

КардиоСоматика, 2019
Aim. To study the effect of gender, age, duration of disease and different forms of ischemic heart disease on the stiffness of the vascular wall in patients with arterial hypertension by determining the propagation velocity of the pulse wave.

Photoacoustic microscopy of blood pulse wave [PDF]

, 2012
Blood pulse wave velocity (PWV) is an important physiological parameter that characterizes vascular stiffness. In this letter, we present electrocardiogram-synchronized, photoacoustic microscopy for noninvasive quantification of the PWV in the peripheral

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Central Aortic Pressure Influences Pulse Wave Velocity [PDF]

Hypertension, 2002
To the Editor: The study reported by Lantelme and colleagues1 suggests that increasing heart rate is independently associated with higher aortic pulse wave velocity (PWV). We are concerned that the authors of this study have neither addressed the impact of central aortic pressure changes on PWV nor the presence of potential bias in their study.
