L'antagonismo immanente. Da Tronti a Gramsci

2022

Il presente saggio si pone il compito di tracciare una linea di continuità tra la produzione teorica di Mario Tronti e la scrittura carceraria di Antonio Gramsci in merito alla questione del rapporto, talvolta antinomico talaltra corrispondente, tra antagonismo e immanenza.

Staphylococcus aureus nēsāšana veselu cilvēku starpā

2016

Staphylococcus aureus bieži vien kolonizē nāsis, padarot veselu cilvēku par šo patogēno mikroorganismu nēsātāju. Medicīnas darbiniekiem un medicīnas studentiem, kas ir pakļauti ilgu laika periodu slimnīcas videi, ir lielākais risks kļūt par S.aureus nēsātāju. Nēsātāji darbojas kā pastāvīgi infekcijas avoti. Stafilokoku infekcijas visbiežāk attīstās imūn-novājinātiem pacientiem, tāpēc nēsāšana medicīnas darbinieku vidū ir sevišķi svarīga. Darba mērķis: noteikt S.aureus nēsāšanas biežumu medicīnas fakultātes studentu vidū. Galvenie uzdevumi: 1.Noteikt S.aureus nēsāšanas atkarību no medicīnas fakultātes kursa ( otrais kurss, sestais kurss) – tātad no saskares ar slimnīcas vidi. 2.Noteikt S.aur…

Interactive effects of zearalenone and its metabolites on cytotoxicity and metabolization in ovarian CHO-K1 cells.

2014

Zearalenone (ZEA) is a non-steroidal estrogen mycotoxin with high binding affinity to estrogen receptors. ZEA is rapidly absorbed and metabolized in vivo to α-zearalenol (α-ZOL) and β-zearalenol (β-ZOL). So, mixtures of them may be present in biological systems and suppose a hazard to animals and human health. The aims of this study were to determine the cytotoxic effects of ZEA and its metabolites, alone and in combination in ovarian (CHO-K1) cells during 24, 48 and 72h by the MTT assay; and to investigate the metabolism of the CHO-K1 cells on ZEA, and its conversion into α-ZOL and β-ZOL by CHO-K1 cell after 24 and 48h of exposure. The IC50 value obtained for individual mycotoxins range fr…

Elucidating the aryl hydrocarbon receptor antagonism from a chemical-structural perspective.

2020

The aryl hydrocarbon receptor (AhR) plays an important role in several biological processes such as reproduction, immunity and homoeostasis. However, little is known on the chemical-structural and physicochemical features that influence the activity of AhR antagonistic modulators. In the present report, in vitro AhR antagonistic activity evaluations, based on a chemical-activated luciferase gene expression (AhR-CALUX) bioassay, and an extensive literature review were performed with the aim of constructing a structurally diverse database of contaminants and potentially toxic chemicals. Subsequently, QSAR models based on Linear Discriminant Analysis and Logistic Regression, as well as two tox…

Suppression ofBotrytis cinereacausing the grey mould disease of grape-vine by an aggressive mycoparasite,Pythium radiosum

1999

Pythium radiosum Paul has been found to be an aggressive mycoparasite of Botrytis cinerea which causes grey mould disease on the grape-vine. The mycoparasitic fungus enters the host mycelium, coagulates its protoplasm, empties its contents and finally comes out producing numerous ramifications and sexual structures. When the infected mycelium of B. cinerea is applied to the leaves of the grape-vine, the characteristic grey mould symptoms fail to appear. Since P. radiosum causes no harm to the grape-vine, it can be used as a biological control agent against B. cinerea. A brief account of the mycoparasite and its antagonism towards B. cinerea is discussed here.

A new species ofPythiumisolated from burgundian vineyards and its antagonism towardsBotrytis cinerea, the causative agent of the grey mould disease

2004

During the course of an investigation on the pythiaceous fungi occurring in burgundian vineyards, three isolates of Pythium were found, all of which were characterised by spherical to lemoniform, proliferating sporangia. Only one out of these three isolates produced sexual characters (S-12) after prolonged incubation, but their asexual structures, temperature growth relationship and molecular characteristics were identical. Saprolegnia-type internal proliferation of the sporangia, and Phytophthora-type lemoniform, papillate sporangia were characteristic of all the three isolates. The type specimen is S-12 which is a medium slow growing saprophyte. The sequence of its ITS region of the rDNA …
