A model is described in which transient complete cerebral ischemia is induced in rats by intracardiac injection of potassium chloride. The animals were intubated and mechanically ventilated with a nitrous oxide/oxygen (70:30) mixture. Cardiac arrest was achieved following a brief period of ventricular fibrillation. After 5-6 min, the circulation was restored by cardiopulmonary resuscitation and pa

Patent citations added by examiners are often used as indicators of technological impact and knowledge flows, despite various criticisms. In this study we analyze the distribution of examiner patent citations according to patent characteristics in order to show their limitations. According to our findings, the number of applicant citations included is dependent on the science-base of the technolog

Objectives: To develop and validate a new algorithm to identify patients with rheumatoid arthritis (RA) and estimate disease prevalence using administrative health databases (AHDs) of the Italian Lombardy region. Design: Case-control and cohort diagnostic accuracy study. Methods: In a randomly selected sample of 827 patients drawn from a tertiary rheumatology centre (training set), clinically vali

Boken behandlar det äldsta statliga konstmuseet i Sverige, Kongl. Museum i Stockholms slott, med beaktande av dess tillkomsthistoria, samlingarnas ursprung och uppställning samt överförandet till Nationalmuseum i mitten av 1860-talet. Publikationen bygger på forskning om föremålen och dokumentation i arkiven och ger en helhetsbild som i flera avseenden korrigerar tidigare uppfattningar och ger en

In A Transnational History of the Australian Animal Movement, Gonzalo Villanueva covers the important events that led to the addition of an entirely new issue to the political agenda, transforming the conditions of nonhuman animals into a matter of public concern. Grounded in transnational history, social movement studies, and the emerging field of critical animal studies, A Transnational History

Translation Studies has crossed a tumultuous interval of theorization. But has it passed the linguistic limits instituted by a semiotician like Umberto Eco? Wouldn’t be the time to access more courageously the intersemiotic interregnum with its heterogeneous transfer of signs? As it happens in advertising, concrete poetry, tattoos, and stage or filmed version of famous texts? If we have gradually

Testicular microlithiasis (TM) has been reported in up to 46% of men with testicular cancer. This has given rise to the suspicion that TM is a premalignant condition. In studies of healthy men there is, however, no association between TM and development of cancer. Nonetheless, patients with TM and contralateral testicular cancer, testicular atrophy, inhomogeneous parenchyma, infertility or a histo

Prepositions already formed a grammatical category in the Common German language. New Scandinavian pepositions were established during the preliterary and the early literary periods. In this paper it is demonstraed that most of them were grammaticalizations of prepositional phrases or adverbs linked to a noun by an established preposition. The genesis of these new prepositions is investigated sema

BACKGROUND: Multifocal electroretinogram (mfERG) has the power to discriminate between localized functional losses and overall retinal changes when evaluating retinal injury. So far, full-field ERG has been the gold standard for examining retinal ischemia and the effects of different neuroprotectants in experimental conditions. The aim of the present study was to establish mfERG, with simultaneous
