Typification of the name Galatella sorrentinoi (Asteraceae)
2020
The name Galatella sorrentinoi Todaro (Asteraceae) is lectotypified with a specimen housed in the Herbarium Mediterraneum Panormitanum (PAL). The specimen selected as the lectotype agrees with protologue and with the current usage of the name.
Transnationalism and Settlement of Latvian Emigrants in the Nordic Countries
2021
The intra-European migration flows have fostered debates about the intentions of migrants to settle in their destination country or return to their countries of origin. Based on a quantitative analysis of survey data ('N' = 1391), this article presents a typology of migration patterns among migrants from Latvia in the Nordic countries. Using two dimensions—attachment to the destination country and attachment to the country of origin—the article identifies and characterises the following four migration patterns: (1) bi-nationals, (2) settlers, (3) footloose migrants and (4) isolated migrants who focus on their country of origin and are willing to return (separated).
Research Regarding Physical Testing in the Military Pentathlon at the 50 M Race with Obstacles
2019
Abstract The research started from the necessity of finding new ways to physical test the military students that are part of the military pentathlon 50 m race with obstacles team. The research methods used was the experiment method, using two groups: the first group was the control group and the second the experiment group. The experiment consisted in testing the students at: 50 m speed running, 800 m resistance running, push-ups, and specific testing like: 50 m swimming with obstacles, 8 km run in varied terrain. The results of our investigation showed that calculation of the statistical significance of the differences between the averages of the two samples showed significant values at p&…
La tradición clásica como referencia de vanguardia: la Antigüedad griega y romana en la obra del pintor Gregorio Prieto (1897-1992)
2019
This article analyses the impact of classical tradition on the artistic production of Gregorio Prieto (1897-1992), painter par excellence of the Generation of 1927. It will be discovered how this influence, far from becoming a conservative reference, would constitute an incentive for his entailment with the avant-garde, especially with surrealism. Although the classic trace is found with more intensity in the creations produced during his Roman years, between 1928 and 1929, when he also made important trips to Sicily and Greece, Greece and Rome would nevertheless continue to be constitutive of his aesthetic experience throughout his later and extensive career.

NOSIP, a novel modulator of endothelial nitric oxide synthase activity.
2001
Production of nitric oxide (NO) in endothelial cells is regulated by direct interactions of endothelial nitric oxide synthase (eNOS) with effector proteins such as Ca2+-calmodulin, by posttranslational modifications such as phosphorylation via protein kinase B, and by translocation of the enzyme from the plasma membrane caveolae to intracellular compartments. Reversible acylation of eNOS is thought to contribute to the intracellular trafficking of the enzyme; however, protein factor(s) that govern the translocation of the enzyme are still unknown. Here we have used the yeast two-hybrid system and identified a novel 34 kDa protein, termed NOSIP (eNOS interacting protein), which avidly binds …
Reconstruction of Peritoneal-like Structure in Three-Dimensional Collagen Gel Matrix Culture
1997
The peritoneum is a serous membrane consisting of different kinds of cells and extracellular matrix components (ECM). The aim of the present study was to develop a three-dimensional (3D) in vitro culture system for possible investigation of pathological conditions of the peritoneum. Human omental mesothelial cells (MC) and endothelial cells from the umbilical vein (EC) were cultivated either on (MC) or in (EC) a preformed type I collagen matrix. In 3D culture mesothelial cells showed their phenotypical in vivo characteristics and the synthesis of a new basal membrane (BM). Endothelial cells developed vessel-like structures, produce a BM and express E-selectin after TNF-alpha stimulation. Th…
Inflammation Determines the Pro-Adhesive Properties of High Extracellular D-Glucose in Human Endothelial Cells In Vitro and Rat Microvessels In Vivo
2010
BACKGROUND: Hyperglycemia is acknowledged as an independent risk factor for developing diabetes-associated atherosclerosis. At present, most therapeutic approaches are targeted at a tight glycemic control in diabetic patients, although this fails to prevent macrovascular complications of the disease. Indeed, it remains highly controversial whether or not the mere elevation of extracellular D-glucose can directly promote vascular inflammation, which favors early pro-atherosclerotic events. METHODS AND FINDINGS: In the present work, increasing extracellular D-glucose from 5.5 to 22 mmol/L was neither sufficient to induce intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion mo…
Analysis of the Biological Response of Endothelial and Fibroblast Cells Cultured on Synthetic Scaffolds with Various Hydrophilic/Hydrophobic Ratios: …
2009
In this study we developed polymer scaffolds intended as anchorage rings for cornea prostheses among other applications, and examined their cell compatibility. In particular, a series of interconnected porous polymer scaffolds with pore sizes from 80 to 110 microns were manufactured varying the ratio of hydrophobic to hydrophilic monomeric units along the polymer chains. Further, the effects of fibronectin precoating, a physiological adhesion molecule, were tested. The interactions between the normal human fibroblast cell line MRC-5 and primary human umbilical vein endothelial cells (HUVECs) with the scaffold surfaces were evaluated. Adhesion and growth of the cells was examined by confocal…
Apigenin‐induced nitric oxide production involves calcium‐activated potassium channels and is responsible for antiangiogenic effects
2007
Summary. Background: The dietary flavonoid apigenin (Api) has been demonstrated to exert multiple beneficial effects upon the vascular endothelium. The aim of this study was to examine whether Ca2+-activated K+ channels (KCa) are involved in endothelial nitric oxide (NO) production and antiangiogenic effects.Methods: Endothelial NO generation was monitored using a cyclic guanosine monophosphate radioimmunoassay. KCa activity and changes of the intracellular Ca2+ concentration [Ca2+]i were analyzed using the fluorescent dyes bis-barbituric acid oxonol, potassium-binding benzofuran isophthalate, and fluo-3. The endothelial angiogenic parameters measured were cell proliferation, [3H]-thymidine…
