Efeito do exercício prévio na determinação da potência crítica

The objective of this study was to analyze the influence of previous exercise on the determination of critical power (CP). Seven apparently healthy nontrained males, of 18 to 25 years, participated of this study. The subjects were submitted, in different days to the following protocols in a cyclergometer: 1) one progressive test until voluntary exhaustion for the determination of lactate threshold (LL), maximal oxygen uptake (VO2max) and its corresponding intensity (IVO2max); 2) six constant workload tests at 95,100 and 110% IVO2max until exhaustion with and without a previous exercise at 70% , in random order. The exhaustion times (tlim) at 95, 100 and 110% IVO2max were adjusted forme thress models of two parameters to estimate CP and anaerobic work capacity (AWC) [P=CTAn/tlim)+CP; tlim = CTAn/(P-PC); P=PC.tlim+ CTAn]. The model with the lowest standard error was considered for the estimation of CP. The tlim at 95% IVO2max was similar without (501 ± 140 s) and with previous exercise (473 ± 99 s). However, the tlim at 100% (381 ± 103 s and 334 ± 101 s) and 110% IVO2max (267 ± 163 s and 227 ± 68 s) was significantly longer with previous exercise. There was no significant difference in CP and AWCat conditions without (200 ± 27 W and 23 ± 11 kJ, respectively) and with previous exercise (212 ± 30 W and 18 ± 8 kJ, respectively). It can be concluded that the parameters of the relationship between power and time were not modified by the previous severe exercise

501(C)(3) Nonprofit Organizations in Nebraska: 2008

Nonprofit organizations are important to the quality of life in communities. They exist in complex variety and include church congregations, private schools, service clubs, business leagues, social and recreational clubs, labor unions, farm bureaus, community theaters, neighborhood organizations and many more. Only the largest of nonprofits are likely to have employees, with most relying upon volunteers to meet their human resource requirements. They obtain their financial resources through donations, investments, grants and fee based activities, such as festivals and educational programs.

Trends in aortic aneurysm- and dissection-related mortality in the state of Sao Paulo, Brazil, 1985-2009: multiple-cause-of-death analysis

Background: Aortic aneurysm and dissection are important causes of death in older people. Ruptured aneurysms show catastrophic fatality rates reaching near 80%. Few population-based mortality studies have been published in the world and none in Brazil. The objective of the present study was to use multiple-cause-of-death methodology in the analysis of mortality trends related to aortic aneurysm and dissection in the state of Sao Paulo, between 1985 and 2009. Methods: We analyzed mortality data from the Sao Paulo State Data Analysis System, selecting all death certificates on which aortic aneurysm and dissection were listed as a cause-of-death. The variables sex, age, season of the year, and underlying, associated or total mentions of causes of death were studied using standardized mortality rates, proportions and historical trends. Statistical analyses were performed by chi-square goodness-of-fit and H Kruskal-Wallis tests, and variance analysis. The joinpoint regression model was used to evaluate changes in age-standardized rates trends. A p value less than 0.05 was regarded as significant. Results: Over a 25-year period, there were 42,615 deaths related to aortic aneurysm and dissection, of which 36,088 (84.7%) were identified as underlying cause and 6,527 (15.3%) as an associated cause-of-death. Dissection and ruptured aneurysms were considered as an underlying cause of death in 93% of the deaths. For the entire period, a significant increased trend of age-standardized death rates was observed in men and women, while certain non-significant decreases occurred from 1996/2004 until 2009. Abdominal aortic aneurysms and aortic dissections prevailed among men and aortic dissections and aortic aneurysms of unspecified site among women. In 1985 and 2009 death rates ratios of men to women were respectively 2.86 and 2.19, corresponding to a difference decrease between rates of 23.4%. For aortic dissection, ruptured and non-ruptured aneurysms, the overall mean ages at death were, respectively, 63.2, 68.4 and 71.6 years; while, as the underlying cause, the main associated causes of death were as follows: hemorrhages (in 43.8%/40.5%/13.9%); hypertensive diseases (in 49.2%/22.43%/24.5%) and atherosclerosis (in 14.8%/25.5%/15.3%); and, as associated causes, their principal overall underlying causes of death were diseases of the circulatory (55.7%), and respiratory (13.8%) systems and neoplasms (7.8%). A significant seasonal variation, with highest frequency in winter, occurred in deaths identified as underlying cause for aortic dissection, ruptured and non-ruptured aneurysms. Conclusions: This study introduces the methodology of multiple-causes-of-death to enhance epidemiologic knowledge of aortic aneurysm and dissection in Sao Paulo, Brazil. The results presented confer light to the importance of mortality statistics and the need for epidemiologic studies to understand unique trends in our own population.

Bestandsaufnahme und Kritik der Versuche zur Integration der Völkerkunde/Ethnologie in den Schulunterricht /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 68

Diese Arbeit ist der Versuch einer Bestandsaufnahme der Diskussion um die Rolle des Fachs Eth¬nologie in den allgemeinbildenden Schulen. Eine solche Übersicht zu den im deutschsprachigen Raum veröffentlichten Beiträgen lag bis dahin noch nicht vor. Sie reicht zurück bis zum Ende des 19. Jahrhunderts. Im vorliegenden Papier wurden die grundlegenden Argumentationen dargelegt, mit denen Fachvertreter und -vertreterinnen ein völkerkundliches/ethnologisches Engagement in den Schulen, in Schulbüchern und bei der Lehrerausbildung forderten. Mit einem historisch vertieften Vergleich dieser Argumentationen wurde angestrebt, Kontinuitäten und Brüche in der Diskussion darzustellen. Diese Perspektive ermöglichte zum einen die Darstel¬lung von älteren und kaum mehr rezipierten Beiträgen in einem größeren Rahmen, zum anderen jedoch auch eine Kritik der vorliegenden, oft nur vordergründig verschiedenen Ansätze. Im Schlusskapitel stellte der Autor essentialistische/relativistische und universalistische Ansätze gegenüber und formulierte darauf basierend Ausgangspunkte eines weiteren schulischen Engagements im Rahmen einer vergleichenden Sozialwissenschaft Ethnologie. Im Anhang der Arbeit befindet sich eine chronologische Biblioghraphie all jener Beiträge, die Ethnologen und Ethnologinnen zur Integration ihres Fachs in die Schulen verfassten.

Ahmedabad | Laboratorio di architettura moderna Il National Institute of Design (1961-68) fra contatti internazionali ed echi della tradizione

Oggetto della ricerca è lo studio del National Institute of Design (NID), progettato da Gautam Sarabhai e sua sorella Gira, ad Ahmedabad, assunta a paradigma del nuovo corso della politica che il Primo Ministro Nehru espresse nei primi decenni del governo postcoloniale. Obiettivo della tesi è di analizzare il fenomeno che unisce modernità e tradizione in architettura. La modernità indiana, infatti, nacque e si sviluppò con i caratteri di un Giano bifronte: da un lato, la politica del Primo Ministro Nehru favorì lo sviluppo dell’industria e della scienza; dall’altro, la visione di Gandhi mirava alla riscoperta del locale, delle tradizioni e dell’artigianato. Questi orientamenti influenzarono l’architettura postcoloniale. Negli anni ‘50 e ’60 Ahmedabad divenne la culla dell’architettura moderna indiana. Kanvinde, i Sarabhai, Correa, Doshi, Raje trovarono qui le condizioni per costruire la propria identità come progettisti e come intellettuali. I motori che resero possibile questo fermento furono principalmente due: una committenza di imprenditori illuminati, desiderosi di modernizzare la città; la presenza ad Ahmedabad, a partire dal 1951, dei maestri dell’architettura moderna, tra cui i più noti furono Le Corbusier e Kahn, invitati da quella stessa committenza, per la quale realizzarono edifici di notevole rilevanza. Ad Ahmedabad si confrontarono con forza entrambe le visioni dell’India moderna. Lo sforzo maggiore degli architetti indiani si espresse nel tentativo di conciliare i due aspetti, quelli che derivavano dalle influenze internazionali e quelli che provenivano dallo spirito della tradizione. Il progetto del NID è uno dei migliori esempi di questo esercizio di sintesi. Esso recupera nella composizione spaziale la lezione di Wright, Le Corbusier, Kahn, Eames ibridandola con elementi della tradizione indiana. Nell’uso sapiente della struttura modulare e a padiglione, della griglia ordinatrice a base quadrata, dell’integrazione costante fra spazi aperti, natura e architettura affiorano nell’edificio del NID echi di una cultura millenaria.

In-vivo-Tumorbiologie mittels 68 Ga-PET: Beurteilung der p-Glykoprotein-Aktivität in Weichgewebe-Tumoren sowie Diagnose und Therapie von Knochenmetastasen

Krebs ist eine der häufigsten Krankheiten und stellt eine der wichtigsten medizinischen Herausforderungen des 21. Jahrhunderts dar. Eine frühzeitige Diagnose ist dabei essentiell für eine individuell angepasste Therapie zur Verbesserung der Lebensqualität und -erwartung der Patienten. Hierbei kommen der 68Ge/68Ga-Generator und das daraus resultierende PET-Nuklid 68Ga immer stärker in den Fokus von Wissenschaft und Medizin. rnrnFür eine erfolgreiche Therapie stellt die Chemoresistenz (Multi-Drug-Resistance) zahlreicher Tumore eine schwerwiegende Komplikation dar. Für das Therapieversagen ist die Aktivierung des Transportproteins p-Glykoprotein (pGP) maßgeblich mit verantwortlich. Mit Hilfe der Schiff’schen Base [68Ga]MFL6.MZ konnte die Aktivitätsänderung von pGP unter verschiedener Beeinflussung erstmals in vivo beobachtet werden. So zeigte sich, dass sich unter azidotischen Bedingungen in Tumoren die Aktivität des pGP erhöht und somit vermehrt auch Zytostatika, die pGP-Substrate sind, aus den Tumoren transportiert werden. Durch Aufklärung der Abhängigkeit der pGP-Aktivität von dessen Signalkaskade konnte gezeigt werden, dass durch eine Blockade der MAP-Kinase p38 eine Erniedrigung der pGP-Aktivität zu verzeichnen ist. Die ebenfalls in der Signalkaskade eingebundene MAP-Kinase ERK1/2 hingegen spielt hier nur eine untergeordnete Rolle.rnrnNeben dem Versagen der Chemotherapie stellt auch die Metastasierung eines Malignoms massive Einschnitte in die Lebensqualität von Erkrankten dar. Befallen die Metastasen das Skelett eines Menschen, wird dies zumeist erst spät registriert. 68Ga-markierte Bisphosphonate bieten nun die Möglichkeit, Patienten quantitativ auf Knochenmetastasen hin untersuchen zu können. So konnten zu Beginn einfache Phosphonate wie EDTMP und DOTP nicht die nötige in vivo Stabilität bzw. hohe radiochemische Ausbeuten liefern und sind damit für die Anwendung am Menschen uninteressant. Jedoch die DOTA-basierten Bisphosphonate allen voran der Ligand BPAMD zeigen ein großes Potential. In vivo-Versuche an Ratten mit Knochenmetastasen zeigten, dass sich [68Ga]BPAMD an den Metastasen anreichert und einen sehr guten Kontrast zum gesunden Knochen darstellt. Der Tracer konnte erstmals am Menschen angewendet werden und zeigte in ausgewählten Regionen eine höhere Anreicherung als eine zuvor durchgeführte PET-Aufnahme mit [18F]Fluorid. Der Ligand BPAMD bietet außerdem den Vorteil, neben 68Ga auch andere dreiwertige Radionuklide wie das therapeutische 177Lu komplexieren zu können. Durch Studien zur Komplexbildung und Stabilität konnte auch [177Lu]BPAMD in der klinischen Anwendung erprobt werden und zeigte eine Anreicherung an den Knochenmetastasen. So ist es nun möglich, Knochenmetastasen mittels 68Ga-PET zu diagnostizieren, eine entsprechende Dosisberechnung anzustellen und anschließend mit dem gleichen Liganden eine Therapie mit [177Lu]BPAMD durchzuführen.
