Effect Of Mirthful Laughter On Vascular Function [PDF]

open access: yes, 2010
In contrast to the well-established scientific evidence linking negative emotional states (e.g., depression, anxiety, or anger) to increased risk for cardiovascular disease, much less is known about the association between positive emotional states (e.g.,

Saxagliptin Prevents Increased Coronary Vascular Stiffness in Aortic-Banded Mini Swine

open access: yesHYPERTENSION, 2018
Increased peripheral conduit artery stiffness has been shown in patients with heart failure (HF) with preserved ejection fraction. However, it is unknown whether this phenomenon extends to the coronary vasculature. HF with preserved ejection fraction may

Angiogenic and angiostatic factors in renal scleroderma-associated vasculopathy [PDF]

open access: yes, 2017
BACKGROUND: The angiogenesis in systemic sclerosis (SSc) is impaired. An imbalance of pro-angiogenic factors and angiogenesis inhibitors has been implicated in the progression of peripheral microvascular damage, defective vascular repair and fibrosis ...

Dill extract induces elastic fiber neosynthesis and functional improvement in the ascending aorta of aged mice with reversal of age-dependent cardiac hypertrophy and involvement of lysyl oxidase-like-1 [PDF]

open access: yes, 2020
Elastic fibers (90% elastin, 10% fibrillin-rich microfibrils) are synthesized only in early life and adolescence mainly by the vascular smooth muscle cells through the cross-linking of its soluble precursor, tropoelastin.

Regulation of blood vessel stiffness by focal adhesions of vascular smooth muscle [PDF]

open access: yes, 2013
Thesis (Ph.D.)--Boston UniversityThe operation of the cardiovascular system is inherently mechanical. Changes in the stiffness of the vascular tree have been implicated in various pathophysiologic states, and increased aortic stiffening with age is an ...

Persistent Vascular Collagen Accumulation Alters Hemodynamic Recovery from Chronic Hypoxia [PDF]

open access: yes, 2012
Pulmonary arterial hypertension (PAH) is caused by narrowing and stiffening of the pulmonary arteries that increase pulmonary vascular impedance (PVZ). In particular, small arteries narrow and large arteries stiffen. Large pulmonary artery (PA) stiffness

Sensitivity analysis and uncertainty quantification of 1D models of the pulmonary circulation [PDF]

open access: yes, 2018
This study combines a one-dimensional (1D) model with micro-CT imaging and hemodynamic data to quantify uncertainty of flow and pressure predictions in the pulmonary arteries in a control and hypoxia induced hypertensive mouse. We use local and global sensitivity and correlation analysis to determine parameters that can be inferred from the model and ...

Long term effects of mesoglycan on brachial arterial stiffness and MMP-9/TIMP-1 system in patients with metabolic syndrome [PDF]

open access: yes, 2018
Objectives: The aim of this study was to evaluate the chronic effects of mesoglycan on the vascular remodeling in patients with metabolic syndrome (Mets).

Tumor stiffness extends its grip on the metastatic microenvironment [PDF]

open access: yes, 2017
The increased stiffness of a tumor triggers a multitude of responses that aid cancer cell dissemination. Stiffness-induced expression of CCN1 mediates autocrine signaling in the endothelium to upregulate N-Cadherin levels.

Unraveling the vascular fate of deformable circulating tumor cells via a hierarchical computational model [PDF]

open access: yesarXiv, 2019
Distant spreading of primary lesions is modulated by the vascular dynamics of circulating tumor cells (CTCs) and their ability to establish metastatic niches. While the mechanisms regulating CTC homing in specific tissues are yet to be elucidated, it is well documented that CTCs possess different size, biological properties and deformability.
