This research was based on a study regarding the myth, the landscape and then man in Bolivian literature, a country whose cultural tradition transcends myth and reality, with an exotic nature, inherited from extraordinary people from a remote time, with archeological remains that show its glory, making it particular among other Latin American literatures. To contextualize the literary study of this nation, rich in fantasy literature, understanding its traits in the current literature, we have sought to rescue the history of its first inhabitants, the Kollas, and the cultural reference they inherited and reviewed in the acculturation process between indigenous and Spanish people. This study is based on the contributions of Latin American theorists, such as Antonio Conejo Polar, Nestor Canclini, the Cuban ethnologist Fernando Ortiz, and especially the concept of transculturation of the Uruguayan critic Ángel Rama. Thus, we have tried to rescue a study about the Andean past, approaching the fundamentals of mythic component in literature, addressing landscape and nature as the ones that illustrate, characterize and give life to the mythical characters and social problems of the Andean man

Diese These besteht aus der Analyse der Enteignungsverhältnisse und der Misselung, welche in den Texten der Ursprung des Kunstwerkes und die Hymnen Hölderlins vorkommen. Germanien und der Rhein sind in den 30en-Jahren letzten Jahrhunderts von Martin Heidegger verfasst worden. Ab anwendung der kritischen Methodologia von Harold Bloom und der starken Texgestaltung von Richard Rorty wird es deutlich, dass die Heideggers Lesungen der Hölderlins Poesia als ei Ersatzversuch der von Hegel entwickelte Kulturgeschichte ab deutescher Überlieferung klassicher Studien, die das tragische Erlebnis der alten Griechen als grundlegender Punkt des Westen Daseins vorbringen, verstanden werden können. So verlegt Heidegger die Aufbauachse der Entstehungserzälung des Abendlandes in Richtung Dichtkunst, indem er in seiner Wendung zum Dichterischen gleichzeitig auf der Suche nach einer abweichenden Feststellung der vorherrschaftlichen These ist, in welcher die Tragödie das grosse Antrittsereignis der westlichen Zivilisation darstellt, und darüber hinaus noch der Herstellung einer innigen Verbindung zwischen der Poesie von Hölderlin und Hesiudus, um die Enge der dichterischen Überinstimmung zu zeigen, welche die alten Griechen und die zeitegemässigen Deutschen verbrände. Dieser geistige Aufbau Heideggers hat man somit als ein überholungsversuch Hegels Einfluss und Denkungsart zur Vollendung der von Nietzsche begonnenen Überwindungsaufgabe des Hegelianismus´zu verstehen

Primary aldosteronism (PA) is a common form of endocrine hypertension previously believed to account for less than 1% of hypertensive patients. Hypokalemia was considered a prerequisite for pursuing diagnostic tests for PA. Recent studies applying the plasma aldosterone/plasma renin activity ratio (ARR) as a screening test have reported a higher prevalence. This study is a retrospective evaluation of the diagnosis of PA from clinical centers in five continents before and after the widespread use of the ARR as a screening test. The application of this strategy to a greater number of hypertensives led to a 5- to 15-fold increase in the identification of patients affected by PA. Only a small proportion of patients ( between 9 and 37%) were hypokalemic. The annual detection rate of aldosterone-producing adenoma (APA) increased in all centers ( by 1.3-6.3 times) after the wide application of ARR. Aldosterone-producing adenomas constituted a much higher proportion of patients with PA in the four centers that employed adrenal venous sampling ( 28 - 50%) than in the center that did not (9%). In conclusion, the wide use of the ARR as a screening test in hypertensive patients led to a marked increase in the detection rate of PA. Copyright © 2004 by The Endocrine Society

Once considered rare, primary aldosteronism (PAL) is now regarded as the commonest potentially curable and specifically treatable form of hypertension. At Greenslopes Hospital Hypertension Unit (GHHU), the decision in 1991 to screen all (and not just hypokalemic or resistant) hypertensives by aldosterone/renin ratio (ARR) testing led to a 10-fold increase in detection rate of PAL and four-fold increase in removal rate of aldosterone-producing adenomas (APAs). The GHHU/Princess Alexandra Hospital Hypertension Unit PAL series stands at 977 patients and 250 APAs removed with hypertension cured in 50-60% (remainder improved). Reliable detection requires that interfering medications are withdrawn (or their effects considered) before ARR measurement, and reliable methods (such as fludrocortisone suppression testing) to confirm PAL. Adrenal venous sampling is the only dependable way to differentiate APA from bilateral adrenal hyperplasia. Genetic testing has facilitated detection of alucocorticoid-remediable, familial PAL. Identification of mutations causing the more common familial variety described by GHHU in 1991 should further aid in detection of PAL. (C) 2003 Elsevier Ireland Ltd. All rights reserved.

Recognition that primary aldosteronism (PAL) is a common specifically treatable form of hypertension and that most patients are normokalemic has led to a marked increase in demand for aldosterone/renin ratio (ARR) testing as a means of screening for this disorder. The value of this screening test depends on an appreciation of many factors (such as diet, posture, time of day, presence of hypokalemia, medications, age, and renal function), which can affect the results, on the care with which these factors are either controlled or their effects taken into account, and on access to reliable and reproducible assays for renin and aldosterone. Even then, physiological day-to-day variability reduces the value of a single estimation, and repeated testing is necessary before a decision that PAL is highly likely (warranting further testing) or highly unlikely can be made. Provided that testing of aldosterone suppressibility is always carried out to confirm or exclude the diagnosis, and the subtype is determined by hybrid gene testing and adrenal venous sampling, wide application of the ARR can have a major beneficial clinical impact with improved therapeutic outcomes, including possible cure in those with unilateral disease.

Monogenic mutations leading to excessive activation of the mineralocorticoid pathway result, almost always, in suppressed renin and hypertension in adult life and sometimes in hypokalaemia and alkalosis, which can be severe. In most of these syndromes, precise molecular changes in specific steroidogenic or effector genes have been identified, permitting appreciation of (1) pathophysiology, (2) great diversity of phenotype and (3) possibility of genetic methods of diagnosis. Yet to be achieved elucidation of the genetic basis of familial hyperaldosteronism type 11, the most common and clinically significant of them, will enhance detection of primary aldosteronism, currently the commonest specifically treatable and potentially curable form of hypertension. While classic, complete-phenotype presentations of monogenic forms of mineralocorticoid hypertension are rarely recognised, more subtle genetic expression causing less florid manifestations could represent a significant proportion of so-called 'essential hypertension.'

Primary aldosteronism (PAL) is caused by the autonomous over-production of aldosterone. Once thought rare, it is now reported to be responsible for 5–10% of hypertension. Familial hyperaldosteronism type II (FH-II), unlike familial hyperaldosteronism type I, is not glucocorticoid-remediable and not associated with the hybrid CYP11B1/CYP11B2 gene mutation. At least five times more common than FH-I, FH-II is clinically, biochemically and morphologically indistinguishable from apparently sporadic PAL, suggesting that its incidence maybe even higher. Studies performed in collaboration with C Stratakis (NIH, Bethesda) on our largest Australian FH-II family (eight affected members) demonstrated linkage at chromosome 7p22. Similar linkage at this region was also found in a South American FH-II family (DNA provided by MI New, Presbyterian Hospital, New York). Mutations in the exons and intron/exon boundaries of the PRKARIB gene (which resides at 7p22 and is closely related to PRKARIA gene mutated in Carney complex) have been excluded in our largest Australian FH-II family. Using more finely spaced markers, we have confirmed linkage at 7p22 in these 2 families, and identified a second Australian family with evidence of linkage at this locus. The combined multipoint LOD score for these 3 families is 4.87 (θ=0) with markers D7S462 and D7S2424, which exceeds the critical threshold for genome-wide significance suggested by Lander and Kruglyak (1995), providing strong support for this locus harbouring mutations responsible for FH-II. A newly identified recombination event in our largest Australian family has narrowed the region of linkage by 1.8 Mb, permitting exclusion of approximately half the genes residing in the original reported 5Mb linked locus. In addition, we have strongly excluded linkage to these key markers in two Australian families (maximum multipoint LOD scores −3.51 and −2.77), supporting the notion that FH-II may be genetically heterogeneous. In order to identify candidate genes at 7p22, more closely spaced markers will be used to refine the locus, as well as single nucleotide polymorphism analysis.
