On the Accuracy of Cadastral Marks: Statistical Analyses to Assess the Congruence among GNSS-Based Positioning and Official Maps
2022
Cadastral marks constitute a dense source of information for topographical surveys required to update cadastral maps. Historically, in Italy, cadastral marks have been the cartographic network for the implementation of mapping updates. Different sources of cadastral marks can be used by cadastral surveyors. In recent years, the cadastre is moving toward a digital world, and with the advancement of surveying technology, GNSS CORS technology has emerged in the positioning of cadastral marks. An analysis of congruence among cadastral marks using GNSS CORS and official maps is missing. Thus, this work aims to analyze the positional accuracy of some cadastral marks, located in Palermo, Italy, wi…
High-resolution records of growth temperature and life history of two Nacella limpet species, Tierra del Fuego, Argentina
2020
Stable isotope ratios in patelloid limpets of the genus Patella have been established as proxies for coastal environmental change at sub-monthly resolution along the eastern North Atlantic and Mediterranean Sea. Nacella deaurata (Gmelin, 1791) and N. magellanica (Gmelin, 1791) are common intertidal species of patelloid limpets inhabiting the coast of Tierra del Fuego, Argentina/Chile and are commonly found in Holocene archaeological deposits. Here, we examine oxygen and carbon isotope ratios (δ18Oshell and δ13Cshell, respectively) of modern specimens of N. deaurata and N. magellanica to test the hypotheses that: 1) they form their shells in isotopic equilibrium with ambient water; and 2) pr…

Salix breviserrata Flod., novedad para la flora palentina
2016
Hemos encontrado una pequeña población del sauce rastrero Salix breviserrata Flod., novedad para la provincia de Palencia. Esta localización representa el emplazamiento más meridional de la corología global de este taxon alpino, que alcanza el norte de la Península Ibérica. S. breviserrata está catalogado como Vulnerable en la Lista Roja de la flora vascular española, lo que afianza el ya conocido valor florístico del entorno del macizo de Valdecebollas (Palencia, España). We found a small formation of brushes and low scrubs willow dominated by Salix breviserrata Flod., new taxon for the province of Palencia. This location represents the southernmost of the global chorology of this alpine s…
Biomolecular conjugation inside synthetic polymer nanopores via glycoprotein-lectin interactions
2011
We demonstrate the supramolecular bioconjugation of concanavalin A (Con A) protein with glycoenzyme horseradish peroxidase (HRP) inside single nanopores, fabricated in heavy ion tracked polymer membranes. Firstly, the HRP-enzyme was covalently immobilized on the inner wall of the pores using carbodiimide coupling chemistry. The immobilized HRP-enzyme molecules bear sugar (mannose) groups available for the binding of Con A protein. Secondly, the bioconjugation of Con A on the pore wall was achieved through its biospecific interactions with the mannose residues of the HRP enzyme. The immobilization of biomolecules inside the nanopore leads to the reduction of the available area for ionic tran…
Influence of anti-inflammatory flavonoids on degranulation and arachidonic acid release in rat neutrophils.
1994
We assessed the effects of 24 flavonoid derivatives, reported as anti-inflammatory, on lysosomal enzyme secretion and arachidonic acid release in rat neutrophils. Amentoflavone, quercetagetin- 7-O -glucoside, apigenin, fisetin, kaem pferol, luteolin and quercetin were the most potent inhibitors of β-glucuronidase and lysozyme release. The first com pound was also able to inhibit basal release. These flavonoids besides chrysin and to a reduced extent, naringenin, significantly inhibited arachidonic acid release from membranes. A correlation between degranulation and arachidonic acid release was found for this series of compounds. Structureactivity relationships and implications for the anti-…

Piedziņas vēršana uz parādnieka naudas līdzekļiem
2016
Latvijas Universitātes Juridiskās fakultātes tiesību zinību maģistra studiju programmas students Toms Rajunčus ir autors maģistra darbam ar tēmu “Piedziņas vēršana uz parādnieka naudas līdzekļiem”. Parādu piedziņa, līdzīgi kā lielākā daļa tautsaimniecības nozaru, ir pakļauta konkrētam tiesiskajam regulējumam, kas nosaka nozares darbības specifiku. Parādu piedziņas tiesiskā regulējuma mērķis, galvenokārt, ir noteikt skaidru kārtību, kādā ir vēršama piedziņa pret parādnieku mantu, lai aizsargātu parādniekus no piedzinēju un izpildinstitūciju patvaļas. Ar grozījumiem Civilprocesa likumā, kas stājušies spēkā 2014.gada sākumā ir būtiski mainījusies kārtība, kādā piemērojams galvenais piespiedu i…
Redox signaling in acute pancreatitis
2015
Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…
