Several assays for gamma-hydroxybutyrate (4-hydroxybutyrate, GHB) have been developed based on the enzyme gamma-hydroxybutyrate dehydrogenase (GHB-DH). Enzymatic oxidation of GHB by NAD+ is coupled to diaphorase-mediated reduction of pro-dye to yield colored product. GHB-DH from Ralstonia eutropha was cloned and expressed as a stable fusion protein easily purified by affinity chromatography. Quantitative initial velocity and endpoint versions of the assay in solution are described. Michaelis-Menten parameters for oxidation of GHB and ethanol were estimated. A semi-quantitative "dipstick" version of the assay on paper also is described. Both solution endpoint and "dipstick" assays are sensitive to about 0.05 mg GHB/mL using 10 microL of sample. Ethanol at concentrations possible in urine and agents used to stabilize physiological fluids for forensics analysis do not interfere significantly. The "dipstick" assay also allows detection of GHB in alcoholic beverages after evaporation of about one-fourth drop of beverage before testing. The enzymatic assay for GHB is reliable, sensitive, inexpensive and rapid. 相似文献
Thirty-six male students, drawn from a sample of 1195, were interviewed to obtain a personal history. A battery of projective psychological tests (Rorschach and TATs) were also administered to them. The students were divided into four groups of nine each, Jewish radicals (JR), Christian radicals (CR), Jewish moderates (JM), and Christian moderates (CM), to test the significance of religious background as it related to political outlook. Eight significant psychological variables were found and defined. No differences were found between JMs and CMs. Radicals differed from moderates on three variables: negative identity, masochistic surrender, and treating people as concepts. In addition, JR subjects demonstrated consistently a wandering fantasy, flight from the mother, the mother as salient, and machismo as psychological variables. CRs were not characterized by any of these variables. As with both groups of moderates, the father of the CRs was psychologically salient, but unlike the moderates, CTs perceived their fathers as flawed. The possible dynamic meaning of these configurations is discussed, as are their possible relationship to radical behavior and radical political ideology.This study was supported by grants from the American Jewish Committee and The National Science Foundation (GS35307A).Director of Resident Education, McLean Hospital.

The legislative process in the tax field and the administrative process for the issuance of regulatory and interpretative material by the Treasury Department are closely coordinated. The same persons and interests both inside and outside of Government are involved in both processes. There is thus continuity of expertise, understanding of what is at stake, adversary viewpoints, and Washington knowhow. The preparation of administrative material within the Treasury is a task for those technical personnel and policy officials who in varying degrees also have a voice in the preparation of the Treasury's legislative position and the legislative development of statutory language. The outside forces who watch legislative activity also closely watch administrative activity and seek to shape the latter just so they do the former. The response of the Treasury is much the same in both situations, and governed by the policies, attitudes and predilections of tax policy officials and career personnel. 相似文献
The military manpower demands created by U.S. operations in Afghanistan and Iraq are causing extraordinary strains on recruitment, and the desirable size of the U.S. armed forces has become a topic of national concern. One key issue is the balance between active-duty forces and the reserve components, citizen-soldiers who face numerous service-related issues that the active-duty forces do not and who have their own unique sociology. We cannot continue to rely on the reserves for missions such as Iraq and Afghanistan, but must look to the use of short-term active-duty enlistments, drawn from recent college graduates, to perform duties currently being performed by reservists and even active-duty personnel. 相似文献
If there is no single long-standing American grand strategy, one nonetheless sees through the course of U.S. history the tracks of a grand strategy. It started with the idea of a U.S. monopoly in the Western Hemisphere, along with balances of power in the chief theaters of the world; with belief in the primacy of sea and air power and the need for an economic system to support these; and the objective of transforming international politics. Since 9/11, even if the strategic hierarchy, intensity, and political basis have changed, the Bush administration has largely been continuing in this same project, with a sensible strategy but poorly considered tactics. 相似文献
