Adversa divi Augusti. Pliny the Elder: Naturalis Historia 7. 147–150

The life-work of Augustus and its memory is usually illustrated by the Res gestae as well as the historical pieces of Tacitus, Suetonius and Cassius Dio. This cultural memory omits the Augustus-portrait of the chapters 147–150 of Book 7 of the Naturalis Historia, which summarize the life or more exactly the misfortunes of the life of Rome’s first emperor. This anti-Res gestae divi Augusti is unique not only in ancient literature but in the context of the Naturalis Historia as well. Critics have advocated different explanations. This paper is devoted to an analysis of these chapters in the context of the textual unit that organically contains them, and which culminates in them

Long-Term Exposure of Lead Acetate on Rabbit Renal Tissue

Background: Lead has been widely used in different industries for ages. It is one of the heavy metals, highly poisonous even at low doses, and has biochemical, physiological and behavioral side effects on human and animals. It has been shown that lead has toxic effects on different tissues such as neural and genitourinary tissues, cardiovascular systems and blood. Therefore, high attention has been paid to its environmental pollutions. Objectives: Although many histological and biochemical studies have reported about the effects of lead on the renal tissue, there are a few studies about the ultrastructure and morphometric effects of lead on the kidney. Hence, the aim of this study was the evaluation of morphology and morphometrics of rabbit renal urinary barrier ultrastructure following long-term exposure to lead acetate. Materials and Methods: In this experimental study, 20 male New Zealand rabbits were divided into control and test groups (10 in each). The test group was injected intraperitoneally with chronic dose (8.5 mg/kg of body weight) of lead acetate and for the control group the same volume of normal saline was used, every other day for 10 weeks. After anesthetizing, the biopsies of renal tissues were taken for light and electron microscopic morphometric and morphologic analyses. Results: Long-term exposure to lead acetate caused histopathology effects including dilatation, congestion, nuclei heterochromatic effects, increase in diameter of renal tubules and urinary barrier thickness in rabbit renal tissue. Conclusions: Quantitative and qualitative results of long-term lead acetate exposure showed many histopathology side-effects, especially in the urinary barrier.

Evaluation of Anteroposterior Lip Positions in the Most-Favored Iranian Facial Profiles Using Silhouette

Objective: One of the most important goals of orthodontic treatment is to create an esthetic, well balanced facial profile. However, the components of a wellbalanced Iranian facial profile have not yet been established. The purpose of this study was to evaluate the anteroposterior lip position of the Iranian population and to compare the perception of orthodontists, dental students and orthodontic patients using a series of silhouettes with varying anteroposterior lip positions. Materials and Methods: Average female and male silhouette profiles were constructed from the profiles of 30 Iranian men and women with a normal skeletal relationship. The lips in each average profile were protruded or retruded in 2-mm increments and the 7 images were arranged randomly. Thirty orthodontists, 30 dental students and 30 orthodontic patients were asked to score each silhouette from 1 (very bad) to 5 (very good). Results: Both the orthodontists and the students preferred the average profile for men and slightly more retruded lip position for women. Orthodontic patients had a wide range of preference for men and selected more retruded lip positions for women. The least-favored profile was the most protrusive in the 3 groups. Conclusion: These findings suggest that Iranian orthodontists, dental students and orthodontic patients prefer an average profile for men and slightly retruded profiles for women

Genetic diversity of Fusarium solani isolates from black pepper (Piper nigrum L.) in Malaysia by ISSR marker

For effective management and control of yellowing disease, inter-simple sequence repeat (ISSR) markers were employed to investigate genetic diversity among 34 isolates of Fusarium solani, which had been isolated from major growing areas of black pepper in Malaysia. Over 15 primers, with fragment sizes ranging from 200 bp to 3600 bp, and a total of 253 amplified loci were amplified in all 34 isolates, with an average of 17 bands per primer; among which 248 (98.02 %) were polymorphic. High genetic diversity at species level was revealed (Nei’s gene diversity h = 0.2671 and Shannon information index I = 0.4134, respectively). Sarikei population was found to have a higher degree of polymorphism compared to other populations. The dendrogram generated from UPGMA cluster analysis categorized the 34 F. solani isolates into two major clusters based on Jaccard’s similarity coefficients. Cluster I contained a unique isolate. Cluster II contained 33 isolates which were split into two different subclusters. Results showed that the clusters were not related to geographic origins. Meanwhile, ISSR fingerprinting generated highly polymorphic markers that could be used to study genetic characterization of F. solani and to clarify phylogenic relationships, as well as useful for efficient management of yellowing disease and finding breeding programmes to find cultivars of black pepper that are resistant to F. solani

Dispersion, Performance and Durability of Pt Nanoparticles on Carbon for PEM Fuel Cell Catalysis

The main objective of this work has been to develop the understanding of the effect of Pt particle dispersion on activity and durability of the Pt/C electrocatalysts. In order to have such understanding, extensive testing of the electrocatalysts with different structure ex-situ and in-situ was needed. The first step was to synthesize the electrocatalysts with desired structural and thus electrochemical features. Wet impregnation and three forms of polyol techniques were used and Pt/C catalysts with isolated and aggregated particles with the flexibility to choose the dominant phase were synthesized. The isolated, aggregated and film-coat Pt nanoparticles on carbon black, carbon nanofiber and carbon nanotube were studied physico-chemically and ex-situ electrochemically. Then three samples, the catalysts with aggregated, with only isolated and with film-coat Pt nanoparticles were tested in a fuel cell before and after an accelerated degradation test (ADT) with N2/harmix and also the exposure to CO. Isolated particles presented higher ORR activity followed by film-coat and finally aggregated particles. However, the relative durability (the percentage in performance loss upon ADT) had an opposite trend. The CO tolerance of catalysts with isolated particles was higher than for those with aggregated particles, but recovery of the fuel cell performance after being exposed to CO was slightly higher for catalysts with aggregated particles than for those with isolated particles. Dynamic electrochemical impedance spectroscopy (dEIS) was only applied to catalysts with aggregated particles, and performance and degradation as a function of cathode catalyst layer (CCL) thickness was only studied for catalysts containing isolated particles only. dEIS proved to be a convenient tool for investigation of small changes in the electrode, and it was possible to detect changes in electrode performance that would go practically un-detected by cyclic voltammetry and CO stripping. Electrodes with different thickness based on cathode electrodes with Pt loadings of 10 wt%, 20 wt%, and 30 wt% (containing only isolated Pt particles), were tested in a H2|O2 fuel cell before and after an ADT. The initial electrochemical activity was found to be independent of CCL thickness but in diluted oxygen, the activity was strongly dependent on the CCL thickness or Pt-to-carbon ratio. There was a much larger reduction in cell voltage for the sample with 10 wt% Pt loading comparing with the other two samples that was attributed to the local current density. We suggest that the local current density for this sample crosses a border between two Tafel regimes upon ADT while the 20% and 30% sample remained in the same Tafel regime also after the degradation

Od „Skóry Satyra” do „Barbarzyńcy wypchanego”. Wersje mitu Marsjasza w literaturze węgierskiej.

The tragic myth of Marsyas challenging Apollo was eternalized in Ovid’s wonderful works (Fasti, Metamorphoses). To this day, the ar­ chetypical Ovidian story has attracted the attention of Hungarian literature. The essay proceeds from the interpretation of the original narrative, which has become an unavoidable point of reference for contemporary Hungarian works. These texts enter into intertextual dialogue with each other not only because of the similar topic. It is the meaningfulness of the body, the body as a textual representational strategy that becomes the common point which joins these texts into the discourse about the body. This approach from the side of corpore­ al narratology invites a reading of Gergely Péterfy’s The Stuffed Bar‑ barian, which can be interpreted as the most special rewriting of the Marsyas narrative.Tragiczna historia pojedynku Marsjasza z Apollinem uwieczniona została przez Owidiusza w jego arcydziełach: Kalendarzu poetyckim i Metamorfozach. Utrwalony przez poetę mityczny archetyp cieszy się po dziś zainteresowaniem literatury węgierskiej, niespotykanie silnym zwłaszcza po II wojnie. W niniejszym szkicu wskazano drogę od in­ terpretacji pierwotnego mitu jako nieuniknionego punktu odniesienia dla omawianych współczesnych tekstów literatury węgierskiej – ku in­ tertekstualnemu dialogowi, w jaki wchodzą one pomiędzy sobą, nie tylko ze względu na wspólny temat, ale także włączenie ich w dys­ kurs o ciele. Proponowane przez Autorkę spojrzenie od strony narracji korporalnej pozwala odczytywać Barbarzyńcę wypchanego (Kitömött barbár / Stuffed barbarian) Gergely’a Péterfy’ego jako najbardziej swoistą wersję opowieści o Marsjaszu

Comparison of methods for determination of glomerular filtration rate: low and high-dose Tc-99m-DTPA renography, predicted creatinine clearance method, and plasma sample method

The gamma camera uptake method with Tc-99m-DTPA (diethylenetriaminepentaacetic acid) is a simple method for determination of glomerular filtration rate (GFR), and is less time-consuming than other methods, but its diagnostic accuracy is debated. Gate’s method (low-dose; LD), the high-dose method (HD), the predicted-clearance method, and the plasmaclearance method with Tc-99m-DTPA are compared in this study. We also performed GFR measurement and diuretic renography simultaneously. Tc-99m DTPA renography was performed in 36 patients aged 18–72 years with a wide range of renal function (serum creatinine 1.37 ± 0.49mg/dl).GFR was determined by four methods: the gamma camera uptake method with low-dose Tc-99m DTPA (Gates, LD); the gamma camera uptake method with high-dose Tc-99m DTPA (HD); the predicted creatinine clearance method (Cockcroft– Gualt, CG); and the plasma sample clearance (PSC) method using a mono-exponential curve. The PSC method was chosen as reference. The regression equations for the CG, Gates (low-dose), and HD methods against the PSC method were 28.68 + 0.80X (r = 0.72; P value\0.0001, RMSE = 21.65 ml/min/ 1.73 m2), 6.19 + 0.79X (r = 0.90; P value\0.0001, RMSE = 10.64 ml/min/1.73 m2), and 6.53 + 0.88X (r = 0.93; P value\0.0001, RMSE = 9.35 ml/min/ 1.73 m2), respectively. In comparison with determination of GFR by the PSC method, the CGmethod tended to overestimate GFR while, perversely, the LD and HD methods tended to underestimate GFR. The three methods were in agreement with the PSC method but the high-dose GFR method resulted in less error in estimation of GFR. Furthermore, GFR measurement and diuretic renography could be performed at the same time when the high-dose method was used. Because of the low cost and negligible radiation burden, this method might be preferred for routine practice in nuclear medicine
