No full textThis article examines the creative use of the German language in the works of Ilma Rakusa, a writer born in Slovakia and currently living in Zurich, Switzerland. In particular, the analysis deals with the collection of poems Impressum: Langsames Licht. Gedichte (2016) and the literary creativity of the author who mixes with great skill multilingual play on words, sounds, voices and alliterations, rendered through a creative manipulation of the German language. Chinese words, Hebrew names as well as entire English and French sentences can be found in Ilma Rakusa’s poems, which lead to a rhythmic, multilingual and partly rhymed texture
Expression of Endothelin-1 and Endothelin Receptor A in Canine Ovarian Tumours
No full textOvarian tumours have a low incidence in bitch. Endothelin (ET-1) and endothelin A receptor (ET-A) are overexpressed in human ovarian cancer. Twenty canine ovarian tumours and five normal samples were first evaluated by western blotting and then immunohistochemically for ET-1 and ET-A expression. Seventeen out of twenty tumours were ET-1 positive. Eight out of twenty tumours were ET-A immunohistochemically positive. At molecular level both proteins were proven to be expressed in normal as well as in tumour samples. Our results show that ET-1 and ET-A are overexpressed in canine ovarian tumours, suggesting a potential role of these two molecules in canine ovarian carcinogenesis
Chaos and Non-linear Tools inWebsite Visits
No full textThe present work is an application of linear and non-linear tools, with
particular attention to the chaotic dynamics, in order to analyze the daily visits to the
Italian newspaper website “La Repubblica”. The series is examined, using the time
chart, the recurrence plot and the power spectrum. In the phase space, the detrend
series consists of 5 clusters of points, explained by the frequency distribution that
is centred on 3 values. The analysis is performed by calculating the embedding
dimension, Lyapunov exponents and the correlation dimension that suggests the
existence of an attractor. A non-linear forecast of the following values is made.
In conclusion, some theoretical issues on the characteristics of a chaotic system
emerge
Malignant mixed sex cord-stromal tumour in a stallion.
No full textA 30-year-old Standardbred stallion was examined for unilateral scrotal swelling. Physical and
ultrasound examinations revealed a painless enlarged left testis with a non-homogeneous
echogenicity, when compared with the controlateral testis. The stallion underwent left unilateral
orchiectomy. Grossly, the excised testis was irregularly enlarged (12 ×9×9cm; weight: 530g) and
firm. The sections showed that testicular parenchyma was replaced by a lobulated, greyish-white
mass, which involved the epididymal head. At microscopy, a dual Leydig and Sertoli cell tumour
component could be seen. Neoplastic Sertoli cells were prevalent and presented pleomorphic cells,
mitotic figures and occasional vascular invasion. Tumour patterns showed tubular and solid areas,
cord-like or diffuse in appearance, among which newly formed Leydig cell nests and low-density
fibrillar bundles were interposed. Immunohistochemically, a weak to moderate immunostaining for
vimentin, AE1/AE3 cytokeratin, α-1-antitrypsin and CD99 antigens was found in the growing
Sertoli cells, whose nuclear MIB-1 labelling index scored 13±2%. The Leydig tumour cells, on the
other hand, displayed a moderate to strong positivity for α-inhibin, vimentin, AE1/AE3 cytokeratin,
neurone-specific enolase and CD99. On the basis of these findings, a diagnosis of malignant mixed
sex cord-stromal tumour was made

Imaging of canine neoplastic reproductive disorders
No full textDiagnostic imaging plays an essential role in the diagnosis and management of reproductive neoplasia in dogs and cats. The initial diagnosis, staging, and planning of surgical and ra-diation treatment and the response to therapy all involve imaging to varying degrees. Routine ra-diographs, ultrasound, nuclear medicine, and cross‐sectional imaging in the form of computed tomography (CT) and magnetic resonance imaging (MRI) are routinely used in canine reproductive disorders. The choice of imaging modality depends on many factors, including the level of referral and the pathological information required. The biological behaviour of the tumour also guides the choice of imaging in cancer staging, and imaging may play an important role in guiding serial tumour biopsy during the course of therapy. The sophistication of imaging modalities is in-creasing exponentially. Each modality has advantages and disadvantages in terms of cost, availa-bility, sensitivity, specificity, and qualities of anatomic versus functional imaging
Assessment of vascular perfusion kinetics using contrast-enhanced ultrasound for the diagnosis of prostatic disease in dogs
No full textVascular perfusion was assessed in 10 dogs without prostatic abnormalities and 26 dogs with prostatic disease using contrast-enhanced ultrasound. The time to reach peak contrast intensity (TTP) and peak perfusion intensity (PPI) were measured, and histological biopsies were collected from each dog. Biopsies confirmed normal prostate (n = 10), benign prostatic hyperplasia (n = 11), mixed benign pathology (n = 9), prostatitis (n = 1), prostatic malignancy [adenocar- cinoma (n = 4); leiomyosarcoma (n = 1)]. In normal dogs, mean PPI was 16.8% ± 5.8 SD, and mean TTP was 33.6 ± 6.4 s. Benign conditions overall were not statistically different from normal dogs (p > 0.05); for benign prostatic hyperplasia, mean PPI was 16.9 ± 3.8%, and mean TTP was 26.2 ± 5.8 s; for mixed benign pathology mean PPI was 14.8 ± 7.8%, and mean TTP was 31.9 ± 9.7 s; for prostatitis, PPI was 14.2%, and TTP was 25.9 s. The malignant conditions overall had perfusion values that differed from the normal dogs (p < 0.05), although evaluation of the data for individ- ual malignancies did not demonstrate a consistent trend; for adenocarcinomas, the PPI was numerically higher with a mean of 23.7 ± 1.9%, and the mean TTP was 26.9 ± 4.8 s, whilst for the dog with leiomyosarcoma values were numerically lower with a PPI of 14.1% and TTP of 41.3 s. Contrast- enhanced ultrasound appears to offer some ability to docu- ment differences in perfusion that may differentiate between malignant and benign lesions, although studies with larger numbers of animals are required to confirm this contention
Prostatic Perfusion in the Dog Using Contrast-Enhanced Doppler Ultrasound
No full textUltrasonography has become the imaging modality of choice
for evaluation of the prostate gland in the dog. Unfortunately,
despite providing excellent images, it may be difficult to
differentiate the common canine prostatic diseases with
ultrasound because many have a similar ultrasonographic
appearance. Real-time contrast-enhanced ultrasound was used
to monitor and characterise the normal perfusion pattern and
perfusion dynamics of the canine prostate gland when using
a micro bubble contrast agent. In all contrast studies, the
prostatic artery, entered the prostate gland on the dorso-lateral
surface then tunnelled into the prostatic capsule and branched
into many small parenchymal arteries which were directed
medially towards the urethra to supply the body of the
prostate gland. The flow of the contrast medium into the
prostatic parenchyma was visible after 15 s. During the washin
phase, there was an homogenous enhancement of the
prostatic parenchyma. During the wash-out phase, an homogenous
decrease of the echogenicity was visible in all cases
