Journal ArticleDOI
A role for VEGF as a negative regulator of pericyte function and vessel maturation.
Joshua I. Greenberg,David J. Shields,Samuel Barillas,Lisette M. Acevedo,Eric A. Murphy,Jianhua Huang,Lea Scheppke,Christian Stockmann,Randall S. Johnson,Niren Angle,David A. Cheresh +10 more
TL;DR: A role is defined for VEGF as an inhibitor of neovascularization on the basis of its capacity to disrupt VSMC function and reveals a dichotomous role for V EGF and VEGf-R2 signalling as both a promoter of endothelial cell function and a negative regulator of VSMCs and vessel maturation.
Journal ArticleDOI
Semaphorin 3A suppresses VEGF-mediated angiogenesis yet acts as a vascular permeability factor
TL;DR: A novel role is defined for Sema3A both as a selective inhibitor of VEGF-mediated angiogenesis and a potent inducer of VP.
Journal ArticleDOI
Uncultured adipose-derived regenerative cells (ADRCs) seeded in collagen scaffold improves dermal regeneration, enhancing early vascularization and structural organization following thermal burns.
Philippe Foubert,Samuel Barillas,Andreina D. Gonzalez,Zeni Alfonso,Sherry Zhao,Isaac Hakim,Carol Meschter,Mayer Tenenhaus,John K. Fraser +8 more
TL;DR: It is demonstrated that seeding uncultured ADRCs onto CBM dermal substitute enhances wound angiogenesis, blood vessel maturation and matrix remodeling, as well as improving matrix properties and enhancing healing of the grafted wound.
Journal ArticleDOI
Carotid Endarterectomy as the Criterion Standard in High-Risk Elderly Patients
TL;DR: Carotid endarterectomy in elderly patients with significant comorbidities, traditionally thought to be a high-risk undertaking, is a safe procedure with periprocedural risks of stroke, death, and MI equivalent to those of younger patients.
Journal ArticleDOI
Role of a Novel Tetrodotoxin-Resistant Sodium Channel in the Nitrergic Relaxation of Corpus Cavernosum from the South American Rattlesnake Crotalus Durissus Terrificus
Rodrigo O. Capel,Fabíola Z. Mónica,Marcovan Porto,Samuel Barillas,Marcelo Nicolas Muscará,Simone A. Teixeira,André Moreira Martins Arruda,Lorenzo Pissinatti,Alcides Pissinatti,André Almeida Schenka,Edson Antunes,César R.D.

TL;DR: Rattlesnake CC relaxation is mediated by the NO-cGMP-PDE5 pathway in a manner similar to mammals and the novel TTX-resistant Na channel identified here may be responsible for the slow response of smooth muscle following nerve stimulation and could explain the extraordinary duration of snake coitus.
