Investigating the Antiproliferative and Antioxidant Properties of Pancratium maritimum L. (Amaryllidaceae) Stems, Flowers, Bulbs, and Fruits Extracts

2018

Pancratium maritimumstems, flowers, bulbs, and fruits extracts were investigated for their antiproliferative and antioxidant properties. Total phenols and total flavonoids were also determined. Thein vitroantiproliferative activity was tested against seven cancer cell lines such as C32, HeLa, MDA-MB-231, PC3, A549, MCF-7, and LNCaP by using SRB assay. Interesting results were obtained with stems ethanol extract (ET1) against C32 cells (IC50of 27.1μg/mL) and fruits aqueous extract (AQ) against MCF-7 cell line (IC50of 36.5μg/mL). To define the antioxidant activity, four tests such as DPPH, ABTS FRAP, andβ-carotene bleaching tests were used.The most promising ABTS scavenging capacity was obser…

Efecto del género y parámetros antropométricos en marcadores de estrés oxidativo e inflamación en situación postprandial

Título Efecto del género y parámetros antropométricos en marcadores de estrés oxidativo e inflamación en situación postprandial Introducción La arteriosclerosis (AE) es la principal causa de las enfermedades cardiovasculares y está relacionada con múltiples factores que son marcadores de inflamación crónica de bajo grado y de estrés oxidativo (EO) contribuyendo desde su inicio en el desarrollo de la disfunción endotelial. La lipemia postprandial (LPP) alterada está asociada con el desarrollo precoz de AE, siendo un factor de riesgo cardiovascular aun en ausencia de hipertrigliceridemia en ayunas. Dado que la mayor parte del día el sujeto lo pasa en situación postprandial, la medida de la li…

Mi descrivi il tuo disegno del Mattoncino Lego? Un’esperienza didattica di matematica nella scuola dell’infanzia

2018

La consapevolezza dell’importanza di guardare, attraverso una lente di tipo matematico, i disegni prodotti dai bambini, considerandoli come strumento diagnostico per quello che D’Amore et al. (2004) chiamano come il “Campo di Esperienza” Spazio, Ordine e Misura, ha dato spunto a questo contributo che discute una sperimentazione didattica condotta in una sezione di scuola dell’infanzia (5 anni). All’interno della stessa è stato chiesto ai bambini di rappresen- tare dei mattoncini Lego con un disegno, e di descrivere successivamente i propri elaborati rintracciando e argomen- tando in essi eventuali segni di scarto numerico-spaziali rispetto al mattoncino osservato/manipolato, attraverso visi…

PICTURES, GESTURES AND DISCOURSES: A CASE STUDY WITH KINDERGARTEN STUDENTS DISCOVERING LEGO BRICKS

The awareness of the importance to look, through a mathematical lens, to the children drawings, gestures and discourses, considering them as diagnostic tools for the mathematics competences, stays at the base of this contribution. It discusses a didactic experience conducted in a Kindergarten (students 5 or 6 years old) in which we asked children to represent and discus a Lego block with a drawing and speech, observed from different prospective. The discussed results seem to us interesting both for researchers in Mathematics Education and for Kindergarten teachers who want to deepen the role of drawing and gestures as an expressive and diagnostic forms to analyze students’ knowledge, abilit…

Liquidation of the Bankruptcy Estate in Poland

2020

The purpose of this study is to present the general principles and general issues of liquidation of the bankruptcy estate under Polish law. It should be stressed that liquidation of the bankruptcy estate is intended to satisfy the creditors of the insolvent debtor. Therefore, the manner of liquidation of the bankruptcy estate has an obvious impact on the final bankruptcy dividend for the creditors. The rules governing the liquidation of the bankrupt’s assets are of the key-importance for the theory of law and the practice. The article defines the directional principles of liquidation of the bankruptcy estate, procedure of liquidation of the bankruptcy estate. The subject of this paper there…

A (1->3)-beta-D-glucan recognition protein from the sponge Suberites domuncula. Mediated activation of fibrinogen-like protein and epidermal growth f…

2004

Sponges (phylum Porifera) live in a symbiotic relationship with microorganisms, primarily bacteria. Until now, molecular proof for the capacity of sponges to recognize fungi in the surrounding aqueous milieu has not been available. Here we demonstrate, for the demosponge Suberites domuncula (Porifera, Demospongiae, Hadromerida), a cell surface receptor that recognizes (1--3)-beta-D-glucans, e.g. curdlan or laminarin. This receptor, the (1--3)-beta-D-glucan-binding protein, was identified and its cDNA analysed. The gene coding for the 45 kDa protein was found to be upregulated in tissue after incubation with carbohydrate. Simultaneously with the increased expression of this gene, two further…

The efficacy of two immunostimulants against Flavobacterium columnare infection in juvenile rainbow trout (Oncorhynchus mykiss).

2009

Abstract Bacterium Flavobacterium columnare is the causative agent of columnaris disease in many wild and farmed fish species. Immunostimulants are used with success in aquaculture against many pathogens, but the ability to improve innate resistance to columnaris disease has not been studied. Fingerling rainbow trout were treated with two immunostimulants, yeast β-glucan and β-hydroxy-β-methylbutyrate (HMB). Selected innate immune function parameters, the production of reactive oxygen species (ROS) by whole blood and by isolated head kidney leukocytes, plasma lysozyme activity and complement bacteriolytic activity, were determined to assess the immune status of fish. The fish were then bath…

The Complement System: Activation and Control

1985

One of the hallmarks of immunology has been analysis and characterization of the C system in biological fluids. It is composed of 11 proteins of the “classical” pathway:1 C1q, C1r, C1s, C4, C2, C3, C5, C6, C7, C8, and C9. There are three proteins of the “alternative” pathway (IUIS-WHO Nomenclature Committee 1981) B, D, and P. Finally, there are four control proteins: C1 inhibitor (Cl¯ INH) and C4b binding protein (C4b-bp) for the classical pathway, I (C3b inactivator or C3b INA) and H (β1 or C3b INA accelerator) for the alternative pathway, and anaphylatoxin inactivator. Due to the dramatic advances in protein chemistry, these 19 distinct serum proteins have been highly purified and charact…
