LO SPECCHIO DEI SASSONI DI DRESDA. DIRITTO TERRITORIALE II. Introduzione, TRADUZIONE, Glossario.
2010
E lo Specchio, come la parte tecnica integrata all’uomo, un cyborg si direbbe oggi, non opera privilegi: chiunque vi si rifletta in una determinata situazione, lo Specchio, che contiene, sia nel testo che nella parte illustrata visi amorfi, darà una faccia a chi vi cade dentro. In quel momento il testo descriverà anche l’aspetto esteriore di quell’uomo che aveva fotografato a priori interiormente, nel suo pensare e nel suo agire. Quello che prima era un teorico modello-monito proteiforme si trasforma in un organismo vivo, operante, imparziale, di giustizia bendata: “E adesso udite per quanto riguarda i crimini, quale tribunale sentenzia su cosa. Il ladro si deve impiccare. Se si verifica pe…
Lo Specchio dei Sassoni di Dresda. Diritto Territoriale I. Introduzione, TRADUZIONE, Glossario.
2009
Il Sachsenspiegel (Specchio dei Sassoni) è un testo interdisciplinare nel quale prevalgono le leggi e la trasformazione lessicale e strutturale della lingua. È il codice, in questo senso, più importante del medioevo tedesco. Questa affermazione è senz'altro esatta, ma anche riduttiva, perché studiare o anche solo leggere il Sachsenspiegel significa fare un "viaggio" nel medioevo tedesco, significa entrare nel mondo dei Sassoni e vivere con loro la loro vita quotidiana. Vuol dire accostarsi alle loro consuetudini, quindi ai loro rapporti interpersonali, capire come si muovono e devono muoversi il feudatario e il gaugravio, lo sculdascio e il capocontadino, e come si comporta una donna sposat…
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…
Beyond Pseudo‐natural Products: Sequential Ugi/Pictet‐Spengler Reactions Leading to Steroidal Pyrazinoisoquinolines That Trigger Caspase‐Independent …
2021
In this work, we describe how stereochemically complex polycyclic compounds can be generated by applying a synthetic sequence comprising an intramolecular Ugi reaction followed by a Pictet-Spengler cyclization on steroid-derived scaffolds. The resulting compounds, which combine a fragment derived from a natural product and a scaffold not found in nature. are both structurally distinct and globally similar to natural products at the same time, and interrogate an alternative region of the chemical space. One of the new compounds showed significant antiproliferative activity on HepG2 cells through a caspase-independent cell-death mechanism, an appealing feature when new antitumor compounds are…
Does low concentration mycotoxin exposure induce toxicity in HepG2 cells through oxidative stress?
2020
The purpose of this study was to determine whether exposure to low concentrations of deoxynivalenol (DON), T-2 toxin (T-2) and patulin (PAT) in a human hepatocellular carcinoma cell line (HepG2) exerts toxic effects through mechanisms related to oxidative stress, and how cells deal with such exposure. Cell viability was determined by the MTT and protein content (PC) assays over 24, 48 and 72 h. The IC
Dabas vielu lipīdu uzkrāšanās un acetilholīnesterāzes inhibīcija cilvēku aknu šūnu līnijā HepG2 in vitro
2022
Taukaino aknu slimība ir viena no izplatītākajām aknu slimībām attīstītajās valstīs, un tiek iedalīta alkohola un ne-alkohola taukaino aknu slimībā. Taukaino aknu slimībai ir potenciāls progresēt līdz steatohepatītam un cirozei, bet joprojām nav atrastas mērķētas terapijas slimības progresijas palēnināšanai. Maģistra darba mērķis ir pētīt Vaccinium ģints ogu izspaidu ekstraktu iedarbību uz acetilholīna koncentrāciju, acetiholīnesterāzes aktivitāti un lipīdu akumulāciju HepG2 šūnu modelī. Pētījuma rezultāti liecina, ka ogu izspiedu ekstrakti samazina lipīdu akumulāciju šūnās un gan ekstrakti, gan zināmais aknu šūnu funkciju uzlabotājs silimarīns inhibē acetilholīnesterāzes (AChE) aktivitāti.…
Selenofēnkumarīnu un selenofēnhinolonu salīdzinošā ietekme uz HepG2 šūnu fermentatīvo antioksidatīvo sistēmu
2015
Latvijas Organiskās sintēzes institūtā izstrādātas metodes jaunu selenofēn[3,2-c] un [2,3-c]kumarīnu un selenofēn[3,2-c] un [2,3-c]hinolonu sintēzei, kuriem pierādīts antiproliferatīvais efekts in vitro. Darbā tika noteikts savienojumu inhibējošais efekts uz trim hepatomas HepG2 šūnu galvenajiem antioksidatīvajiem fermentiem (GPx, TrxR, SOD) ar mērķi noskaidrot savienojumu antiproliferatīvā efekta darbības mehānismus. Pētījumā konstatēts, ka visi savienojumi ir efektīvi GPx inhibitori. TrxR aktivitāti inhibē selenofēnhinoloni un [3,2-c] aizvietotie selenofēnkumarīni, savukārt SOD aktivitāti ietekmē tikai divi no savienojumiem. Kopumā noteikts, ka selenofēnhinoloni ir aktīvāki antioksidatīvo…
