Pros and cons of an aggressive initial treatment with surgery and radioiodine treatment in minimally invasive follicular thyroid carcinoma
No full textBACKGROUND: Currently, surgery alone is the gold standard treatment for minimally invasive follicular thyroid cancer (mi-FTC). CASE PRESENTATION: A case of a mi-FTC diagnosed in 1994 was treated with total thyroidectomy and radioiodine (RAI) ablation, according to the therapeutic algorithm used at that time. Nevertheless, he had a recurrence with distant metastasis after 24 years from the initial treatment. CONCLUSION: Total thyroidectomy and RAI ablation might have delayed the development of distant metastasis but they were not sufficient to avoid disease recurrence. Certainly, remnant ablation simplified the follow-up and the monitoring of serum thyroglobulin allowed the early detection of the biochemical recurrence, but didn’t change the outcome of the disease. Moreover, because of this early detection the patient was exposed to useless biochemical and imaging examinations. The aim of this report is to discuss the pros and cons of an aggressive treatment of a patient with mi-FTC
Effect of topical ophthalmic instillation of rocuronium bromide on the intraocular pressure of kestrels (Falco tinnunculus) and little owls (Athene noctuae)
No full textOBJECTIVE: To assess the effect of rocuronium bromide-induced mydriasis on the intraocular pressure (IOP) of kestrels (Falco tinnunculus) and little owls (Athene noctuae). ANIMALS: 13 adult kestrels and 13 adult little owls. PROCEDURES: All birds were ophthalmologically normal. During the first of 2 treatment periods, a 1% rocuronium bromide solution was topically instilled in both eyes of all birds at a dose of 0.12 mg (12 μL) for kestrels and 0.20 mg (20 μL) for little owls. No ophthalmic treatments were administered during the second (control) treatment period, which was conducted 1 week after the first. During both treatment periods, rebound tonometry was used to measure IOP before rocuronium bromide instillation or at the beginning of the control period (baseline) and at predetermined times after baseline or until the pupillary light reflex returned to normal. All IOP measurements were obtained between 8 am and 5 pm. RESULTS: The mean IOP did not differ significantly from baseline for either species during the control treatment period. During the rocuronium bromide treatment period, complete mydriasis was achieved in all birds. The mean IOP was significantly decreased from baseline and from the corresponding mean IOP for the control period beginning 60 and 30 minutes after drug instillation for kestrels and owls, respectively, and reached its nadir at 60 minutes after drug instillation for both species. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that topical instillation of rocuronium bromide in the eyes successfully induced mydriasis and decreased the IOP of common kestrels and little owls
“but I am also influenced by no such thing”-The Radical Pietist and Theological Author Johanna Eleonora Petersen
No full textJohanna Eleonora von und zu Merlau, verheiratete Petersen, von jeher tief gläubig, veränderte die religiöse Welt des 17. Jahrhunderts. Sie bekannte sich zur Bewegung des Pietismus und vertrat radikale Ansichten, nicht nur im privaten Kreis, sondern als anerkannte und heftig kritisierte theologische Autorin. Ihrem Werk ist eine Studie gewidmet, in der neue Forschungsergebnisse vorgestellt und Leben und Werk dieser bedeutenden Autorin in zeitgenössische Diskurse eingebunden werden.The deeply devout Johanna Eleonora Petersen, whose maiden name was „von und zu Merlau,” changed the religious world of the seventeenth century. She avowed herself to Pietism and held radical views, not only in private but also as an acknowledged and sharply criticized theological author. This study attends to her work. It presents new research results and weaves the life and work of this important author into contemporary discourses
La notion de défectuosité du produit dans les jurisprudences des pays européens
No full textThis work analyses the notion of defective product originally developed by US Courts, then ambiguously defined by the European directive n. 374 of 1985 and differently interpreted and applied by the respective domestic Courts. In particular, some European jurisdictions apply the risk / utility test introduced by the US Courts for design defects cases, although this test is not mentioned by the European Directive. The author, having highlighted the inconsistences of the risk / utility test, proposes an alternative model of classification of defective products according to the elements actually used by judges in order to allocate the liability, as emerging from the text of their decisions. This classification leads to held the manufacturer strictly liable not only for manufacturing defects, but also for those design defects which he was aware of (as in some cases of defective vaccine).Cette étude examine la notion de défectuosité du produit initialement élaborée par les Cours américaines, définie de manière ambigüe par le législateur européen avec la directive n° 374 de 1985, puis différemment interprétée et appliquée par les Cours respectives des pays membres. Notamment certains systèmes juridiques européens appliquent le risk/ utility test élaboré par les Cours américaines pour les cas de défaut de conception du produit, bien que ce test ne soit pas mentionné par la directive européenne. L’auteur, après avoir mis en évidence les incongruences du risk/ utility test, propose un modèle alternatif de classification des cas de produits défectueux sur la base des critères d’imputation de la responsabilité qui sont concrètement utilisés par les juges et tels qu’imagés dans les textes de leurs décisions. Cette reconstruction amène à imputer au fabricant une responsabilité objective non seulement pour les cas de défaut de production, mais aussi pour les cas de défaut de conception dont il était averti (tel que certain cas de vaccin défectueux).Rajneri Karageorgevitch Eleonora.

No full textHebb's idea of a cell assembly as the fundamental unit of neural information processing has dominated neuroscience like no other theoretical concept within the past 60 years. A range of different physiological phenomena, from precisely synchronized spiking to broadly simultaneous rate increases, has been subsumed under this term. Yet progress in this area is hampered by the lack of statistical tools that would enable to extract assemblies with arbitrary constellations of time lags, and at multiple temporal scales, partly due to the severe computational burden. Here we present such a unifying methodological and conceptual framework which detects assembly structure at many different time scales, levels of precision, and with arbitrary internal organization. Applying this methodology to multiple single unit recordings from various cortical areas, we find that there is no universal cortical coding scheme, but that assembly structure and precision significantly depends on the brain area recorded and ongoing task demands

No full textMorphological study of the iris musculature in diurnal and nocturnal raptors
No full textIn literature it is established that the iris musculature consists of striate muscle fibers in birds while in mammals it consists of smooth muscles. Some authors report the presence of smooth muscle tissue also in the iris of some species of birds. In the present study we report on the iris muscle tissues (type of tissue, direction and mean diameter of muscle fibers or cells) in five species of Accipitriformes (diurnal raptors) and four species of Strigiformes (nocturnal raptors) because they show different way of life depending of their predatory behavior. This morphological study was carried out from raptors died or euthanized at the Wild Life Rescue Centre of Sea and Water birds in Livorno (Italy). From histological examination of iris serial radial sections we find both striated and smooth musculature even if with marked differences among analyzed species, not directly correlated with diurnal or nocturnal lifestyle. Striated fibers are always present, mainly with cross direction, throughout the iris stroma, while the histological differences concern the smooth cells. Indeed, harrier and sparrow hawk (Accipitriformes) and great horned owl and little owl (Strigiformes) show a compact layer of cross smooth muscle cells throughout the iris stroma. In the other species analyzed smooth muscle cells are slightly detectable as scattered or not detectable. Since the cross smooth muscle tissue allows to maintain a myotic state for extended periods of time, our results might be correlated more to the predatory behavior than the taxonomic order
