OBJECTIVES The aim of this study was to assess the impact of oral water and intravenous furosemide challenges on blood oxygenation level-dependent magnetic resonance imaging measurements in the kidney and to examine the contribution of R2 (=1/T2) to changes in R2* (=1/T2*). MATERIALS AND METHODS This Health Insurance Portability and Accountability Act-compliant study had institutional review ...
background: in this study the basic radiation properties of n-isopropylacrylamaide polymer gel dosimeter were determined together with verification of its soft tissue equivalency. materials and methods: the nipam gel was prepared and irradiated approximately 2 h after manufacturing. the magnetic resonance (mr) images were made 24 h after irradiation. the nuclear magnetic resonance (nmr) respons...

In the title adduct, 3C(13)H(9)N·C(9)H(6)O(6) or (acr)(3)(btc), associ-ations of one btc and three acr molecules linked by O-H⋯N hydrogen bonds occur. C-H⋯O interactions also occur, resulting in a cyclic hydrogen-bonded synthon R(2) (1)(6). The acr mol-ecules and the btc mol-ecules also form slipped or offset π-π stacking inter-actions [centroid-centroid distances of 3.5212 (17) Å for btc rings...
OBJECTIVE Beta-trace protein concentrations in cerebrospinal fluid (CSF), serum and nasal secretions are investigated with a new quantitative, immunonephelometric assay. RESULTS The mean beta-trace concentration of normal lumbar CSF (18.4 mg/l) and normal serum (0.59 mg/l), from n = 132 control patients, were 10% higher than reported earlier for smaller control groups. The reference range of ...
