Early rise in blood pressure following administration of adrenocorticotropic hormone-[1-24] in humans

1. An elevation in blood pressure has been consistently observed 24 h after adrenocorticotropic hormone (ACTH) administration and is caused by increased ACTH-stimulated cortisol secretion, in association with increased cardiac output. The aim of the present study was to investigate the previously undefined time of onset of this increase in blood pressure in normal humans. 2. Ten normal healthy volunteers received 250 mug ACTH-[1-24], in 500 mL normal saline, infused at a constant rate over 8 h. Six subjects also received a placebo infusion (normal saline only). Blood pressure, heart rate and cortisol levels were determined hourly. Adrenocorticotropic hormone (ACTH-[1-24] plus native ACTH) was measured at 0, 1, 7 and 8 h. 3. Infusion of ACTH-[1-24] produced maximal secretion rates of cortisol, resulting in a mean peak plasma level of 985 +/- 46 nmol/L at 8 h. In response, blood pressure and heart rate rose significantly by 2 h and remained generally elevated for the duration of the infusion. 4. The early onset of haemodynamic responses is consistent with classical steroid receptor-mediated genomic mechanisms, but could be due non-genomic mechanisms. 5. The cardiovascular consequences of therapeutic use of ACTH are well recognized. This results of the present study suggest that even diagnostic administration of ACTH, delivered over a few hours, may raise blood pressure.

Steiner trades that give rise to completely decomposable latin interchanges

In this paper we focus on the representation of Steiner trades of volume less than or equal to nine and identify those for which the associated partial latin square can be decomposed into six disjoint latin interchanges.

Displaying the future: Techno-nationalism and the rise of the consumer in postwar Japan

This paper explains how, in the aftermath of World War II, a type of techno-nationalism emerged that linked being Japanese to science and technology and the increased consumption of electrical appliances. By closely examining official exhibitions, we can see how the state and private sector strongly encouraged this techno-scientific dreaming. Dazzling displays highlighted how the peaceful atom would help lead the nation to achieve high economic growth. At the same time, through the judicious purchase of labor saving appliances, consumers could reconcile the need to spend with the need to save.

Brazil's rise on the international scene: Brazil and the World

Since Cardoso and during Lula's Administration, the international order has undergone significant changes. These changes have allowed the Brazilian foreign policy to mitigate internal effects of an order established by others and, at the same time, to become an active participant in the formulation of the new order. To democratize globalization became the mainspring of Brazilian foreign policy. In the scope, President Lula has maintained the tradition of formulating and programming foreign policy as a State policy, and also has fostered the logistic strategy of incorporation of Brazil into the international scene.

Japan and India: soft balancing as a reaction to China's rise?

What are Indian and Japanese reactions to China's rise in economic, political and military terms? According to realist tradition, their option would be between balancing and bandwagoning. Applying Stephen Walt's balance of threats approach, this work aims to analyze Indian and Japan responses to an increasingly powerful China; its conclusions point to an evolving relationship between India and Japan, in military terms, especially after 2005.

Peaceful rise and the limits of Chinese exceptionalism

Throughout the last thirty years of opening to the world Beijing has stressed that its rise will be peaceful and that, from a strategic point of view, China is exceptional. There are many challenges facing Beijing's response to the US rebalancing to the Asia-Pacific, but we consider that the ones with greater impact are, in point of fact, of a domestic nature and constitute limits to Chinese exceptionalism.

Rise and fall in ischemic heart disease mortality: it may have happened before

The rise in ischemic heart disease(IHD) mortality occurring mostly during the first half of the 20th century is usually associated with economic development and its consequences for people's lifestyles. On the basis of historical evidence, it is postulated that a previous IHD epidemic cycle may have occurred in England and Wales towards the turn of the nineteenth century. The implications of this on causal theories and current etiological research on atherosclerosis are discussed.

The Rise of democracy in Europe and the fight against mass poverty in Latin America: the implications for marxist thought of some recent mainstream papers

Recently a number of mainstream papers have treated the rise of democracy in 19th century Europe and its instability in Latin America in an eminently Marxist fashion. This paper sets out their implications for Marxist thought. With respect to Europe, Marx's emphasis on political action backed by the threat of violence is vindicated but his justification for socialism is not. With respect to Latin America, the unequal distribution of wealth is the cause of political instability that is, in turn, the root cause of mass poverty. In addition it is possible to explain some of the paradoxical characteristics of neo-liberalism and to make a weak argument for socialism in spite of its rejection in Europe.
