A proposito di alcune citazioni della “Vita di Feodosij”
No full textThe present work investigates the structure and the process of adaptation of some scriptural references from the New Testament in the Life of Feodosij Pečerskij. In the vast scriptural repertoire the loci chosen for the analysis gather around a few of the numerous themes, milestones of the monk’s spiritual life. Among the forms of citations and references, moreover, some similitudes and analogies were considered, in which, in addition to the persistent semantic and linguistic connections with the source text, we looked at the user and the possible intentions of the author in the process of building the exemplum
Age-related changes in interstitial norepinephrine. A microdialysis study in spontaneously hypertensive rats
No full textThis study was aimed at evaluating the time course of interstitial norepinephrine (NE) concentrations in the white adipose tissue and at assessing NE release after local perfusion with tyramine hydrochloride (TYR) in rats of different ages. Two groups of eight spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto (WKY) rats, aged 14 to 16 weeks, were studied. The same animals were reexamined at the age of 52 to 54 weeks. A soft microdialysis probe was implanted subcutaneously in the parascapular region and was perfused with Ringer solution (flow rate: 2.0 mu L/min). After an equilibration period, NE levels were monitored for 120 min, following which, TYR (0.1 nmol/min) was perfused for 90 min. Dialysates from each 30 min collection period were analyzed by HPLC using electrochemical detection.
At 14 to 16 weeks, SHR showed higher NE concentrations in dialysates as compared to WKY (1124.0 pg/mL v 541.4 pg/mL; P < .001) and a blunted response to TYR challenge. The net output, estimated by subtracting basal values, was 86.0 pg NE/h in SHR as compared to 212.5 pg NE/h in WKY (P = .005). Differences in basal NE levels persisted in the same aged groups (P < .001) as well as a blunted response to TYR. The net NE output was still lower in SHR as compared to WKY (320.4 pg NE/h v 414.7 pg NE/h in WKY; P = .023). Basal levels of NE in SHR could be accounted for by either a higher amount of the neurotransmitter stored into and released from vescicles or by an increased firing rate of the sympathetic fibers. Since TYR is known to deplete axoplasmic but not vesicular NE available for neurotransmission, the response of SHR to TYR challenge is consistent with an increased turnover rate of NE. Aging was associated with an increased response to TYR in both strains, thus suggesting an age-dependent decline in turnover rates or changes in NE reuptake mechanism
Aflatoxicosis and Vitamins A and E supplementation in Sows: Immunological State in Their Piglets
No full textABSTRACT
The authors’ previous investigations showed that daily administration of 300 ppb of
aflatoxin to sows from day 42–45 of gestation until weaning time, produced indirect
intoxication of their piglets, leading to the exhibition of mild clinical signs of disease
and histological patterns of altered cell-mediated immunity (Cabassi et al., 2002).
Harvey et al. (1995) reported deficient levels of retinol and tocopherol in the tissue
and serum of pigs affected by aflatoxicosis; they suggested that greater amounts of
vitamins E and A are required by the body during the course of this disease and that
both vitamins play a protective and detoxifying role in the presence of aflatoxins.
Based on these considerations, the aim of our research was to assess wherether
vitamin A and E supplements in AF contaminated feedstuff given to sows during
gestation and lactation had a similar protective and detoxifying effect on their offspring.
To verify this, the young animals’ immune status was examined and signs of
any adverse effects were sought by means of haematological and morphostructural
examinations
Езопова басна код Доситеја Обрадовића
No full textThe potential and intrinsic polysemy of the esopic fable made a very flexible means of lively expression over the centuries, as evidenced by the fortune it enjoyed in the traditions of many countries: so was in the literature of the southern Slavs, full of evidences the book tries to bring to light. Bearing multiple messages and meanings, a banner of other literary genres, the classical fable lived an unusual flourishing in the eighteenth century, thanks to its versatility and its didactic-didascalic functions. From the categories of the classical tradition Obradović fable comes out revived and renewed: its centrality, in the author's production, is gathered by the youth writings in which few and essential features already highlight all the didactic and illustrative potentialities: the Basne collection becomes the privileged means of entrusting the message and communicating with a wide audience, a space in which the author can disclose himself to the ideas of the Age of the Enlightenment
A curious case of culinary polysemy
No full textThe term maslo represents a curious case of polysemy in whose microcosm two civilizations seems to meet and collide, Northern and Southern Europe: two universes, butter and oil, silently facing and challenging each other for centuries . The lexeme will be investigated in the relations of form and meaning observed in diachrony, in an attempt to grasp the representation of the polysemic word as a whole, with a dynamic structure constantly changing over tim
Cicerone, Seneca, Giovenale in un saggio sul destino umano.
No full textThe present work intends to investigate the chapter on the old age of Blago Cara Radovana, one of Jovan Ducˇic ́ proses (1926) where the classical spiritual heritage merges into the meditations of a modern man: never as in this work the Serbian writer cites so explicitly his sources: Cicero with the Cato Maior dialogue De Senectute, the XII Letter to Lucilius by Seneca, the X Satire by Juvenal. The contribution attempts to compare some serbian and latin excerpts, echoed not slavishly, but rielaborated by the author through simplifying and omitting, in order to clarify even better his own positions, and coming to conclusions, sometimes discordant from his latin models. The examples of the ancient world, harbingers of a lasting knowledge, are here used as a traditional rhetorical tool, giving to his reasoning a plastic-figurative effect
Un'incursione nel thriller: Poslednja knjiga di Zoran Živković
No full textThe contribution will analyze some of the original features of Poslednja Knjiga (The last book) by Zoran Živković, who does not follow the strict tradition of crime - novels, on the contrary, wishing to transcend reality, the writer overcomes the restrictions of logic and scientifically proved, in order to venture into dimension of the imagery, surreal, dreamy. Živković sets his crime story in a library in Belgrade: inspector Dejan Lukić is entrusted with the case of mysterious deaths, but the investigation, with dramatic turns of events, ends up in a complete nonsense. The truth does not lie in the detection of the murderer (the last book), it is elsewhere, in the mind of the almighty creator - the Author himself, who manipulates the ephemeral lives of his characters. Rich in meta-crime elements, the crime story reveals the complex interaction between the writer's and his creatures' universe
„Teško nama ženama [...]”: la questione femminile in „Tergovci”
No full textThe relation between fathers and children is one of the ideological points of the play chosen by E. Janković, according to the parameters of a bourgeois and mercantile society looking at a useful and modern education and instruction, organic to the needs of the community. The pedagogical commitment of the author from Novi Sad could not ignore some considerations on the key role played by women in the organization of society as a girl, wife and mother, that was to be redefined on the basis of new demands during the 18th century. Goldoni tried to deal with the debate on female education thanks to the lively confrontation between Giannina and Beatrice, being the first model of educated and learned woman, and the latter, prototype of domestic virtue modeled on ancient customs. Behind the comparison between the two figures, Goldoni couldn’t neglect a burning issue of the Enlightment between progressive openness and conservative positions concerning the female question. The work aims at analyzing the two characters in a dialogic interaction that seems to reveal, in the Italian text, a dialectic of opposing models, shaped by Janković in ambivalent and complementary forms. The choice made by Janković, to translate a comedy where the woman is revaluated, by presenting her as main character and by focusing on the problem of her education and instruction, is one of the values of his enlightened program
