Angiogenic expansion of the vasa vasorum (VV) is an important contributor to pulmonary vascular remodeling in the pathogenesis of pulmonary hypertension (PH). High proliferative potential endothelial progenitor-like cells have been described in vascular remodeling and angiogenesis in both systemic and pulmonary circulations. However, their role in hypoxia-induced pulmonary artery (PA) VV expans...

Early events play a decisive role in virus multiplication. We have shown previously that activation of MAPK/ERK1/2 (mitogen-activated protein kinase/extracellular-signal-regulated kinase 1/2) and protein kinase A are pivotal for vaccinia virus (VV) multiplication [de Magalhães, Andrade, Silva, Sousa, Ropert, Ferreira, Kroon, Gazzinelli and Bonjardim (2001) J. Biol. Chem. 276, 38353-38360]. In t...

A standardized analysis of wind retrieval collocations from a set of ERS (C-band VV polarization) and RADARSAT (C-band HH polarization) synthetic aperture radar (SAR) open ocean images is presented. The field validation opportunities, carried out over the past eight years, provided collocated (in time and space) in situ validation data consisting of wind vector and ocean wave spectrum measureme...

A universal C∗-algebra is constructed which is generated by a partial isometry. Using grading on this algebra we construct an analog of Cuntz algebras which gives a homotopical interpretation of KK-groups. It is proved that this algebra is homotopy equivalent up to stabilization by 2×2 matrices to M2(C). Therefore those algebras are KK-isomorphic. We recall the definition of partial isometry. D...

At present, tumor invasion represents the most reliable prognostic factor for primary malignant melanoma. The 10-year survival rate of "thin" melanomas (Breslow less than 0.76 mm) is more than 95%, but approximately 5% of these low-risk tumors do metastasize. In an attempt to determine prognostic markers for "thin" melanomas we investigated the volume-weighted mean nuclear volume (Vv) of primar...

Vaccinia virus (VV) protein A39R has amino acid similarity to the extracellular domain of a glycosylphosphatidylinositol-linked cell surface semaphorin (SEMA7A/CDw108) that has an immunological expression profile and binding properties, thereby implicating A39R as an immunomodulator. Previously, a closely related A39R protein expressed by ectromelia virus was shown to induce cytokine production...

Abstract. Single-pass interferometric synthetic aperture radar (InSAR) enables the possibility for sea ice topographic retrieval despite inherent dynamics of ice. InSAR digital elevation models (DEMs) are measuring scattering center height. The height bias induced by penetration electromagnetic waves into snow and leads to inaccuracies DEM, especially thick deformed with cover. In this study, a...

The purpose of this study was to develop a method for retrieving the rain rate from C-band (∼5.3 GHz) synthetic aperture radar (SAR) images during tropical cyclones (TCs). Seven dual-polarized (vertical-vertical [VV] and vertical-horizontal [VH]) Sentinel-1 (S-1) SAR were acquired in interferometric-wide (IW) swath mode Satellite Hurricane Observation Campaign. These collocated with rates measu...

Background: Our aim is to describe Gallucci’s (VV-G) technique for vesicourethral anastomosis and posterior musculofascial reconstruction (PMFR) during robot-assisted radical prostatectomy (RARP) assess early urinary continence recovery perioperative outcomes. VV-G consists of a “single knot–single running suture” with PMFR. Methods: Between September 2019 October 2021, we prospectively compare...
