As representações de Medeia nas Metamorfoses de Ovídio e na Argonáutica de Apolônio de Rodes

This paper focuses on how the ancient roman poet Ovid’s approach on the mythical character Medea in Metamorphoses Book VII relates to the presence of the character in the Hellenistic greek epic poem Argonautica of Apollonius Rhodius, once the Greek author is known to influence the Roman. Although Ovid’s narrative goes further and focuses on events subsequent to the Argonauts travel, the relationship between the two works allows to address two aspects: the inner monologue and the anxieties of Medea which, by their turn, draw a timeline of the historical influence of Euripedes’ tragedy Medea; going through Apollonius and eventually arriving at Ovid; and the description of Medea’s magical practices and powers, used in Argonautica to protect Jason, which are widely described in Metamorphoses when she rejuvenates Aeson, the hero’s father. It is intended not only to point out aspects of character related to these topics, but primarily to address the mechanisms that can identify the direct influence of Apollonius on Ovid

A figura de Dido em Virgílio e Ovídio: uma análise da rainha cartaginesa na Epopeia e na Elegia

This paper has been written as monograph. Its objective is to create a scene of the way the queen Dido is constructed in Virgil's Aeneid and in Ovid's Heroid 7, aiming a comparison between the two constructions of this character, to establish their resemblances and differences. Thus we are able to build the picture that both writers composed for this so important woman for latin literature

Association between hepatic cholesterol and oleic acid in the liver of rats treated with partially hydrogenated vegetable oil

Objective The aim of the present study was to investigate the lipid profiles of the hepatic and adipose tissues of Wistar rats treated for 21 days with a diet high in saturated fat (high saturated fat, n=6) or high in hydrogenated fat, that is, having 50% partially hydrogenated vegetable oil in its composition (high hydrogenated fat, n=6), and compare them to those of a control group (control group, n=6). Methods Adipose tissue and total hepatic fat were higher in the saturated fat group than in the hydrogenated fat group. Hepatic lipid peroxidation was greatest in the saturated fat group, with consequent lower hepatic vitamin E and A levels. In contrast, serum vitamin A was highest in the saturated fat group. Analysis of hepatic lipid fractions found more cholesterol and less high density lipoprotein-cholesterol in the hydrogenated fat group. The hydrogenated fat group had the highest levels of triacylglycerols, followed by the saturated fat group. Results Significant amounts of trans fatty acids were detected in the hepatic and adipose tissues of the hydrogenated fat group. Among the identified fatty acids, 18:1n9 had a higher positive association with hepatic cholesterol and triacylglycerols, and a higher negative association with high density lipoprotein-cholesterol. Partially hydrogenated vegetable oil promotes greater accumulation of cholesterol and triacylglycerols in the liver than saturated fats. Conclusion Trans fatty acids were incorporated into hepatocytes and adipocytes in a highly efficient manner.

Protein Oxidative Stress and Dyslipidemia in Dialysis Patients

Our aim was to investigate and determine the associations between oxidative stress (OS), dyslipidemia and inflammation in patients treated with continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) using observational cross-sectional study. Twenty patients in CAPD and 48 in HD for at least 8 weeks and aged =18 years were included in the study. Individuals with malignant or acute inflammatory disease were excluded. A control group of 17 healthy individuals was also recruited. The biochemical parameter evaluations were analyzed using colorimetric kits for albumin, serum glucose, total cholesterol (TC) and lipid fractions. To determine the inflammatory status, CRP, IL-6 and TNF-a were analyzed by automated chemiluminescence kits. Plasma advanced oxidation protein products (AOPP) were determined by spectrophotometry. Mean AOPP levels were significantly higher for the HD group compared to the control, and there was no difference in AOPP concentrations between the control and CAPD groups. Dialysis patients had levels of inflammatory parameters higher than controls, and showed a high prevalence of patients with dyslipidemia, especially in CAPD. In the HD group, AOPP was positively correlated with triglycerides (TG) and inversely associated with HDL. Also the HD group was observed to have negative associations between TNF-a and HDL, LDL and TC. In the CAPD group, CRP was inversely correlated with HDL. Hemodialysis patients had increased protein OS and associations of inflammation and dyslipidemia were also observed in these dialysis groups. A more detailed characterization of the relations between oxidative stress and other more traditional risk factors has therapeutic importance, since cardiovascular diseases are the leading cause of death among dialysis patients.

Evaluation of Sperm DNA Peroxidation in Fertile and Subfertile Dogs

Contents Oxidative stress (OS) has been recognized as one of the most important causes of male infertility. The antioxidant activities of seminal plasma and epididymal fluid are not enough to prevent OS, which can damage sperm membranes and DNA, so antioxidant supplementation has been used as a treatment of male infertility. The aim of this experiment was to evaluate the DNA peroxidation before and after antioxidant supplementation with vitamin C and E in dogs with and without fertility problems. A total of eleven dogs were used and were divided in two groups: fertile group (G1), dogs with normal spermiogram (n=5); subfertile group (G2): dogs with low sperm count (<20x106sptz/ml) and/or more than 30% of total sperm pathology (n=6). Both groups received 500mg/day of vitamin C and 500mg/day of vitamin E for 60days. A semen sample was collected before (M1) and after (M2) oral supplementation. Samples were analysed for DNA peroxidation by measuring the 8-hydroxy-2'-deoxyguanosine concentration. No significant difference was observed between groups at either time. Oral supplementation with 500mg/day of vitamin C and 500mg/day of vitamin E did not change the DNA peroxidation in fertile and subfertile dogs.

L'immagine di Roma nella cultura russa tra fine XVIII secolo e inizio XIX secolo

Nella tesi si osserva come nella cultura russa cambiava l’immagine di Roma. Se ancora alla fine del settecento l’antichità romana poteva risultare solamente uno strumento retorico-filologico da utilizzare per fare il proprio discorso più convincente, la generazione dei decabristi la stessa antica romanità la accostava alla cultura e storia russe tramite gli elevati ideali civici. La romanità ora risultava uno strumento di analisi della esperienza storica e politica della Russia anche nel contesto europeo. Da qui nasceva una serie di modelli russi legati all’antica Roma: il Catone di Radiscev, il Bruto dei decabristi, ecc. Vi attingeva generosamente anche una corrente di lirica russo-antica con i suoi ricchi riferimenti agli autori classici, Ovidio, Tacito, Orazio. Nasceva così una specie di Roma antica russa che viveva secondo le sue regole etiche ed estetiche. Con il fallimento dell’esperienza decabrista cambia anche l’approccio alle antichità: ci si distacca dalla visione storico-morale dell’antico, Roma non è più una categoria da emulare, ma una storia a sé stante e chiusa in sé stessa come ogni periodo storico. Essa smette di essere un criterio universale di giudizio etico e morale. Allo stesso tempo, una parte integrante della cultura russa all’epoca era il viaggio a Roma. I russi cresciuti con interesse e amore verso la Roma antica, impazienti ed emozionati, desideravano ora di vedere quella patria dei classici. Era come se fosse un appuntamento fra gli amici di vecchia data. Si affrettava a verificare di persona le muse di storia e di poesia. E con tutto questo si imparavano ad amare tutti i defetti della Roma reale, spesso inospitale, la Roma del dolore e della fatica. La voce importante nel racconto romano dei russi era anche la Roma del cristianesimo, dove ritrovare e ricoprire la propria “anima cristiana”.

Nerve stimulator-guided sciatic-femoral nerve block in raptors undergoing surgical treatment of pododermatitis.

OBJECTIVE To describe the nerve stimulator-guided sciatic-femoral nerve block in raptors undergoing surgical treatment of pododermatitis. STUDY DESIGN Prospective clinical trial. ANIMALS Five captive raptors (Falco peregrinus) aged 6.7 ± 1.3 years. METHODS Anaesthesia was induced and maintained with isoflurane in oxygen. The sciatic-femoral nerve block was performed with 2% lidocaine (0.05 mL kg(-1) per nerve) as the sole intra-operative analgesic treatment. Intraoperative physiological variables were recorded every 10 minutes from endotracheal intubation until the end of anaesthesia. Assessment of intraoperative nociception was based on changes in physiological variables above baseline values, while evaluation of postoperative pain relied on species-specific behavioural indicators. RESULTS The sciatic-femoral nerve block was feasible in raptors and the motor responses following electrical stimulation of both nerves were consistent with those reported in mammalian species. During surgery no rescue analgesia was required. The anaesthesia plane was stable and cardiorespiratory variables did not increase significantly in response to surgical stimulation. Iatrogenic complications, namely nerve damage and local anaesthetic toxicity, did not occur. Recovery was smooth and uneventful. The duration (mean ± SD) of the analgesic effect provided by the nerve block was 130 ± 20 minutes. CONCLUSION AND CLINICAL RELEVANCE The sciatic-femoral nerve block as described in dogs and rabbits can be performed in raptors as well. Further clinical trials with a control groups are required to better investigate the analgesic efficacy and the safety of this technique in raptors.

Alfaxalone anesthesia by immersion in oriental fire-bellied toads (Bombina orientalis).

OBJECTIVES To establish an effective alfaxalone concentration to be used for bath immersion of fire-bellied toads (Bombina orientalis) and to describe its effects. STUDY DESIGN Prospective experimental study. ANIMALS Thirteen oriental fire-bellied toads. METHODS The study was carried out in two phases. The pilot phase involved five animals and aimed to identify an alfaxalone concentration capable of producing induction of anesthesia, defined as immobility with a head down position and loss of responsiveness to stimulation with a stick. The following trial in an additional eight toads used the effective alfaxalone concentration established during the pilot phase. Data from 11 animals (three toads in the pilot study and the eight additional toads) were analyzed. Twenty minutes after immersion in the anesthetic solution, the toads were removed from the bath, and heart rate, respiratory rate, the righting, myotactic and the nociceptive withdrawal reflexes were evaluated every 5 minutes. The loss of both righting and nociceptive withdrawal reflexes was considered indicative of a surgical depth of anesthesia. The time elapsed from anesthetic induction to return of righting reflex, the quality of recovery and the occurrence of undesired effects were observed and recorded. RESULTS Immersion was found to be a suitable anesthetic technique for oriental fire-bellied toads and 200 mg L(-1) alfaxalone concentration produced anesthetic induction in 10 out of 11 toads. Side effects, such as skin irritation, erythema and changes in cutaneous pigmentation, were not observed in any animal. The duration of anesthesia ranged from 10 to 30 minutes after removal of the toads from the alfaxalone bath, and surgical depth of anesthesia was never achieved. CONCLUSIONS AND CLINICAL RELEVANCE It was concluded that alfaxalone anesthesia induced by immersion in a concentration of 200 mg L(-1) is only suitable for toads undergoing non-invasive short procedures.

Alfaxalone versus alfaxalone-dexmedetomidine anaesthesia by immersion in oriental fire-bellied toads (Bombina orientalis)

OBJECTIVE To determine a dexmedetomidine concentration, to be added to an alfaxalone-based bath solution, that will enhance the anaesthetic and analgesic effects of alfaxalone; and to compare the quality of anaesthesia and analgesia provided by immersion with either alfaxalone alone or alfaxalone with dexmedetomidine in oriental fire-bellied toads (Bombina orientalis). STUDY DESIGN Pilot study followed by a prospective, randomized, experimental trial. ANIMALS Fourteen oriental fire-bellied toads. METHODS The pilot study aimed to identify a useful dexmedetomidine concentration to be added to an anaesthetic bath containing 20 mg 100 mL(-1) alfaxalone. Thereafter, the toads were assigned to one of two groups, each comprising eight animals, to be administered either alfaxalone (group A) or alfaxalone-dexmedetomidine (group AD). After immersion for 20 minutes, the toads were removed from the anaesthetic bath and the righting, myotactic and nociceptive reflexes, cardiopulmonary variables and von Frey filaments threshold were measured at 5 minute intervals and compared statistically between groups. Side effects and complications were noted and recorded. RESULTS In the pilot study, a dexmedetomidine concentration of 0.3 mg 100 mL(-1) added to the alfaxalone-based solution resulted in surgical anaesthesia. The toads in group AD showed higher von Frey thresholds and lower nociceptive withdrawal reflex scores than those in group A. However, in group AD, surgical anaesthesia was observed in two out of eight toads only, and induction of anaesthesia was achieved in only 50% of the animals, as compared with 100% of the toads in group A. CONCLUSIONS AND CLINICAL RELEVANCE The addition of dexmedetomidine to an alfaxalone-based solution for immersion anaesthesia provided some analgesia in oriental fire-bellied toads, but failed to potentiate the level of unconsciousness and appeared to lighten the depth of anaesthesia. This limitation renders the combination unsuitable for anaesthetizing oriental fire-bellied toads for invasive procedures.

Alfaxalone-butorphanol versus alfaxalone-morphine combination for immersion anaesthesia in oriental fire-bellied toads (Bombina orientalis)

Oriental fire-bellied toads (Bombina orientalis) are small semi-aquatic anuran species popular as both pets and laboratory animals. Although they are commonly anaesthetized to undergo clinical and experimental procedures, very little is known about their anaesthetic management. The aims of this prospective, randomized, cross-over experimental trial were to establish effective butorphanol and morphine concentrations to be added to alfaxalone for immersion anaesthesia (pilot study), and to compare the anaesthetic and antinociceptive effects of the two drug mixtures (alfaxalone-butorphanol and alfaxalone-morphine), in Bombina orientalis toads. For the actual trial, the toads were randomly assigned to one of two treatment groups: AB and AM, with seven animals in each group, which received alfaxalone-butorphanol and alfaxalone-morphine combinations, respectively, at the concentrations established during the pilot study. Heart rate, respiratory rate, von Frey filament threshold and response to nociceptive withdrawal (NWR), righting and myotactic reflexes were measured at 5 min intervals until return of righting reflex was observed. The investigator who carried out all the measurements was blinded to the treatment. Any undesired effect or complication was noted and recorded. The two treatments were found to be comparable in terms of onset and duration of anaesthesia, and occurrence of undesired effects. However, group AM resulted in lower NWR scores and higher von Frey filament thresholds than group AB. It is concluded that, at the investigated concentrations and in combination with alfaxalone by immersion, morphine provides better antinociception than butorphanol in oriental fire-bellied toads.

Alfaxalone-butorphanol-dexmedetomidine anaesthesia in striped skunks (Mephitis mephitis ) undergoing skin biopsy: two cases

Skunks are becoming increasingly popular as pets. As such, they often undergo a variety of surgical procedures. Two pet skunks undergoing a dermatological examination, including skin biopsy, were anaesthetised with a combination of dexmedetomidine (0.02 mg/kg), butorphanol (0.3 mg/kg), and alfaxalone (4 mg/kg), all administered intramuscularly. Anaesthesia was characterised by rapid onset, absence of detectable side effects and fast recovery after atipamezole administration. Biopsies and toe-pinch did not elicit cardiorespiratory responses, nor did it result in movements or lightening of the anaesthetic depth. Both skunks recovered uneventfully, and showed normal appetite and regular defecation within eight hours following surgery. However, both the animals experienced mild hypothermia at recovery. The dexmedetomidine-alfaxalone-butorphanol combination produced satisfactory anaesthesia in the two skunks, object of this report. This anaesthetic protocol may be used in this species to provide immobility, myorelaxation, unconsciousness and analgesia during skin biopsy or other minor surgical procedures.
