The predators were collected in mate crop in Cascavel and São Mateus do Sul, Paraná, Brazil and some other additional specimens in coffee and maize crops in Ribeirão Preto, São Paulo, Brazil. Illustrations obtained by SEM are given by the first time to the principal structures. Three species of Hemerobius were identified: H. bolivari Banks, 1910; H. domingensis Banks, 1941 and H. gaitoi Monserrat, 1996. H. domingensis is recorded for the first time to Brazil.

This research was carried out in order to compare the occurrence of insects in two maté cultivation systems, native and high tree density. It was performed from August/2000 to September/2001, in a private property in São Mateus do Sul county, in Paraná State, Brazil. Visual inspections of trees and light traps were used to evaluate insect populations in both areas. For Hedypathes betulinus (Klug) (Coleoptera, Cerambycidae), only six adults were observed in the dense area. Based on presence of sawdust at the basis of the trunk, it was obtained that the number of attacked trees did not surpass 11% in either area. For Gyropsylla spegazziniana (Lizer y Trelles) (Hemiptera, Psyllidae), the number of galls per tree was counted and it was observed that the population peak occurred from November to January. For Hylesia spp. (Lepidoptera, Saturniidae) and Thelosia camina Schaus (Lepidoptera, Eupterotidae), the presence of caterpillars on the trees was noticed from September to February, with the population peak in November and December. Adults of Hylesia spp. were more numerous in February and March. Two species that were not previously recorded for Brazil on maté were identified: Hylesia paulex Dognin (83%) and Hylesia remex Dyer (17%), collected with light traps. The maté caterpillar, T. camina was not collected with these traps. Nymphs and adults of Ceroplastes grandis Hempel (Hemiptera, Coccidae) were observed along the year on the branches, with population peak between April and June for the nymphs and from September to November for the adults. It should be considered that despite higher insect incidence in the dense area compared to the native area, the first presents higher yield, and that with a good pest management program the insect problems can be minimized.

Objectives The relevance of the SYNTAX score for the particular case of patients with acute ST- segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI)  has previously only been studied in the setting of post hoc analysis of large prospective randomized clinical trials. A "real-life" population approach has never been explored before. The aim of this study was to evaluate the impact of the SYNTAX score for the prediction of the myocardial infarction size, estimated by the creatin-kinase (CK) peak value, using the SYNTAX score in patients treated with primary coronary intervention for acute ST-segment elevation myocardial infarction. Methods The primary endpoint of the study was myocardial infarction size as measured by the CK peak value. The SYNTAX score was calculated retrospectively in 253 consecutive patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) in a large tertiary referral center in Switzerland, between January 2009 and June 2010. Linear regression analysis was performed to compare myocardial infarction size with the SYNTAX score. This same endpoint was then stratified according to SYNTAX score tertiles: low <22 (n=178), intermediate [22-32] (n=60), and high >=33 (n=15). Results There were no significant differences in terms of clinical characteristics between the three groups. When stratified according to the SYNTAX score tertiles, average CK peak values of 1985 (low<22), 3336 (intermediate [22-32]) and 3684 (high>=33) were obtained with a p-value <0.0001. Bartlett's test for equal variances between the three groups was 9.999 (p-value <0.0067). A moderate Pearson product-moment correlation coefficient (r=0.4074) with a high statistical significance level (p-value <0.0001) was found. The coefficient of determination (R^2=0.1660) showed that approximately 17% of the variation of CK peak value (myocardial infarction size) could be explained by the SYNTAX score, i.e. by the coronary disease complexity. Conclusion In an all-comers population, the SYNTAX score is an additional tool in predicting myocardial infarction size in patients treated with primary percutaneous coronary intervention (PPCI). The stratification of patients in different risk groups according to SYNTAX enables to identify a high-risk population that may warrant particular patient care.

Der am ehesten um 1200 entstandene ,Mauritius von Craûn' gilt als Forschungsproblem. Als gemeinsamen Nenner der kontroversen Zugänge zum Text konstatiert der Aufsatz das Bemühen um eine Verbindung der rätselhaften Erzählung mit einem durch die historische Distanz verlorenen oder verwischten Sinnzusammenhang über einen textexternen missing link. Demgegenüber wird ein themen- und handlungsanalytischer Zugriff vorgeschlagen: Thema der Erzählung ist die im 12. Jahrhundert vorrangig in der Lyrik entwickelte strukturelle Figur der Hohen Minne, die ihre Ästhetik aus einem Paradox gewinnt: Die Möglichkeitsbedingung dieser in beständigem Werben bestehenden Liebe, die niemals erfüllt werden darf, ist ihre Unmöglichkeit. Seine ideelle Füllung erhält das Modell durch eine darin vernetzte Ordnung höfischer Werte wie stæte, triuwe, milte oder mâze. Diese Werte, so die These, ,,erzählt" die Handlung des ,Mauritius': Hier wird nicht nur der Versuch unternommen, lyrische Struktur in narrative Struktur zu verwandeln, sondern auch der, eine ins lyrische Modell eingebettete Ordnung ethischen Wissens zu narrativieren. Einzelne Figurenhandlungen erscheinen aus dieser Perspektive weniger als Bestandteile eines inhaltlichen Entwurfs mit dem Anspruch übergreifender Stimmmigkeit und dem Fluchtpunkt eines Deutungsangebots, sondern als Ausdruck verschieden graduierter Negierungen oder Positivierungen eines bestimmtes Wertes. Hierfür sprechen auch die konstanten Über- oder Unterzeichnungen der Figurenhandlungen, die als markantestes Merkmal der narrativen Faktur des Textes beschrieben werden. Die Mikroanalyse einer einzelnen Szene zeigt ferner, wie die Dichotomie von Statik und Dynamik, die schon dem lyrischen Entwurf der Hohen Minne eingeschrieben ist und die durch die Narrativierung des lyrischen Konzepts im ,Mauritius' zunehmend virulent wird, in Sequenzen aufeinanderfolgender Doppelungen von Bewegung und Zustand auserzählt wird. Insgesamt lässt sich der ,Mauritius' als Erprobung von Verfahren verstehen, eine idealisierte höfische Welt in Analogie zum lyrischen Modus auch im narrativen Modus zu literarisieren: als ein Stück Erzählkasuistik.

The potential for "replacement cells" to restore function in Parkinson's disease has been widely reported over the past 3 decades, rejuvenating the central nervous system rather than just relieving symptoms. Most such experiments have used fetal or embryonic sources that may induce immunological rejection and generate ethical concerns. Autologous sources, in which the cells to be implanted are derived from recipients' own cells after reprogramming to stem cells, direct genetic modifications, or epigenetic modifications in culture, could eliminate many of these problems. In a previous study on autologous brain cell transplantation, we demonstrated that adult monkey brain cells, obtained from cortical biopsies and kept in culture for 7 weeks, exhibited potential as a method of brain repair after low doses of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) caused dopaminergic cell death. The present study exposed monkeys to higher MPTP doses to produce significant parkinsonism and behavioral impairments. Cerebral cortical cells were biopsied from the animals, held in culture for 7 weeks to create an autologous neural cell "ecosystem" and reimplanted bilaterally into the striatum of the same six donor monkeys. These cells expressed neuroectodermal and progenitor markers such as nestin, doublecortin, GFAP, neurofilament, and vimentin. Five to six months after reimplantation, histological analysis with the dye PKH67 and unbiased stereology showed that reimplanted cells survived, migrated bilaterally throughout the striatum, and seemed to exert a neurorestorative effect. More tyrosine hydroxylase-immunoreactive neurons and significant behavioral improvement followed reimplantation of cultured autologous neural cells as a result of unknown trophic factors released by the grafts.
