Cytoprotection assessment against mycotoxins on HepG2 cells by extracts from Allium sativum L

2021

Abstract Cytoprotection effects of Allium sativum L garlic extract from a local garlic ecotype from Ferrara (Italy) on hepatocarcinoma cells, HepG2 cells, is presented in this study. This garlic type is known as Voghiera garlic and has been characterized as PDO (Protected designation of Origin) product. Voghiera garlic extract (VGE) was evaluated against beauvericin (BEA) and two zearalenone (ZEA) metabolites (α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL))-induced cytotoxicity on HepG2 cells by the MTT (3–4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay, over 24 h and 48 h. Direct treatment, simultaneous treatment and pre-treatment strategies at the dilution 1:16–1:00 for VG…

Hormone directed sucrose transport during fruit set induced by gibberellins in Pisum sativum

1987

A new system has been developed to study hormone-directed transport in intact plants during parthenocarpic fruit set induced by gibberellins. Gibberellic acid (GA3) and gibberellin A1 (GA1) applied to unpollinated ovaries of pea (Pisum sativum L. cv. Alaska) promoted sucrose transport from the leaf to the site of hormone application. In vivo experiments showed an early (30 min) accumulation of [14C]-sucrose in ovaries of pea stimulated by gibberellins. This activation of sucrose transport appears to be mediated by gibberellins (GA1, GA3), increasing both loading of phloem with sucrose in the leaf (source) and sucrose unloading in the ovary (sink). The ability of pea tissue segments to take …

Verkkosivustojen omaksumiseen vaikuttavat tekijät

2016

Tässä tutkielma käsiteltiin verkkosivustojen omaksumista ja siihen vaikuttavia tekijöitä. Tutkielmassa tutustuttiin aluksi teknologian omaksumiseen yleisellä tasolla, ja syvennyttiin sitten tarkemmin verkkosivustoihin. Teoreettinen tausta pohjautui teknologian omaksumisen malliin (Technology Acceptance Model, TAM), joka esittää, että kaksi tärkeintä teknologian omaksumista selittävää teki-jää ovat käyttäjän kokema hyödyllisyys ja helppokäyttöisyys. Teknologian omaksumisen tutkimus on olennaista teknologian suunnitteluprosessissa, sillä ymmärrys siihen vaikuttavista tekijöistä voi helpottaa suunnittelijoita kehittämään helpommin hyödyllisiksi ja helppokäyttöisiksi koettuja tuotteita ja palve…

Thermal Denaturation of Pea Globulins (Pisum sativum L.)—Molecular Interactions Leading to Heat-Induced Protein Aggregation

2013

The heat-induced denaturation and aggregation of mixed pea globulins (8%, w/w) were investigated using differential scanning calorimetry (DSC), SDS-PAGE, and size-exclusion chromatography (SEC-HPLC). DSC data showed that the pea proteins denaturation temperature (T(d)) was heating-rate dependent. The T(d) value decreased by about 4 °C by lowering the heating rate from 10 to 5 °C/min. The SDS-PAGE analysis revealed that protein denaturation upon heating at 90 °C was mainly governed by noncovalent interaction. The SEC-HPLC measurements indicated that low-denatured legumin (≈350-410 kDa) and vicilin/convicilin (≈170 kDa) globulins were heat-denatured and most of their subunits reassociated int…

Upper thoracic-spine disc degeneration in patients with cervical pain.

2003

To study the relationship of upper thoracic spine degenerative disc contour changes on MR imaging in patients with neck pain. The relation between upper thoracic and cervical spine degenerative disc disease is not well established.One hundred and fifty-six patients referred with cervical pain were studied. There were 73 women and 77 men with a mean age of 48.6 +/- 14.6 years (range, 19 to 83 years). All MR studies were performed with a large 23-cm FOV covering at least from the body of T4 to the clivus. Discs were coded as normal, protrusion/bulge or extrusion.Degenerative thoracic disc contour changes were observed in 13.4% of patients with cervical pain. T2-3 was the most commonly affecte…

Efectos del ajo en ratones infectados experimentalmente con Echinostoma caproni

2017

Debido a la inexistencia de vacunas antihelmínticas, el control de las infecciones por helmintos intestinales depende fundamentalmente de las medidas higiénico-sanitarias y de la quimioterapia. Sin embargo, la continua aparición de resistencias a los tratamientos habituales hace necesario desarrollar nuevos fármacos contra estos parásitos. En este trabajo, se han investigado los potenciales efectos antihelmínticos del ajo (Allium sativum), a dosis dietéticas, sobre trematodos intestinales trasmitidos por alimentos, empleando para ello el modelo Echinostoma caproni-roedor. Los efectos potenciales del consumo del ajo en la prevención y/o tratamiento de la infección se analizaron siguiendo dif…

Representació del passat : ciència i ficció

2012

Aquest treball fa un repàs del cinema de ficció que ha tractat la prehistòria. Al voltanta de 90 pel·lícules han transmès a la societat idees que mostren quin és el coneixement que a hores d’ara tenim sobre els aspectes més rellevants dels nostres origens, però també reflecteixen les idees preconcebudes que tenim sobre nosaltres mateixos i obre la reflexió a cóm les pel•lícules ens parlen més del present que del passat i la importància que té el context social i històric de les pel•lícules en la representació qu es fa del passat, tant a nivell estètic com el que fa a les qüestions que ens preocupen com a societat humana. This work analyse the fast 90 films of prehistoric past produced until…
