In 9 of 11 ambulatory patients with hyperaldosteronism due to aldosterone-producing adenoma (APA). plasma aldosterone fell during the morning; but in all 7 cases of idiopathic adrenal hyperplasia (IAH) standing caused an increase in plasma aldosterone. Further comparisons of the 9 cases of "typical" APA with the 7 patients with IAH showed other differences. The diurnal curve of plasma aldosterone in APA showed a decline from early morning to late evening, parallel with falling plasma cortisol, regardless ...

In normotensive controls and patients with essential hypertension, plasma aldosterone concentration increased during a morning in the standing position. In 6 cases of hyperaldosteronism with bilateral hyperplasia or indeterminate pathology, plasma aldosterone concentration was above normal, increasing further after standing. Seven of 9 patients with hyperaldosteronism due to unilateral adenoma had high resting plasma aldosterone concentration which fell after standing. The change in plasma aldosterone ...

Thallium-201/technetium-99m pertechnetate subtraction scintigraphy of the parathyroid glands was performed in a prospective study of 33 patients who had undergone bilateral neck exploration for elevated serum calcium and serum parathyroid hormone levels. In 31 cases, the Tl-201/Tc-99m subtraction technique yielded an overall sensitivity of 81%, specificity of 99%, and accuracy of 94% for identifying solitary parathyroid adenomas. Tl-201/Tc-99m subtraction scintigraphy correctly identified 73% of ...

Paranasal sinus osteomas are mostly asymptomatic; however, secondary mucocele can develop if they impede the natural sinus drainage. Such a mucocele can destroy the bone and extend into the adjacent structures. We report on an unusual case of frontal sinus osteoma in a 27-year-old patient, complicated by large secondary mucocele that eroded the bone and extended into the frontal lobe of the brain. Unexpectedly, the patient did not report any visual or other symptoms attributable to central nervous ...

Background. Posttransplant combined lamivudine (LAM) and immunoglobulin (HBIg) prophylaxis is the gold standard in the case of single hepatitis B virus (HBV), but is still not recommended in the case of patients coinfected with hepatitis delta virus (HDV). Methods. We compared two consecutive groups of chronic HDV carriers who survived >6 months after liver transplantation of the risk of recurrence, survival and HBIg requirements: 21 received passive prophylaxis (HBIg group) and 25 were treated with combined ...

The performances in the direct synthesis of hydrogen peroxide (H2O2) with Pd-Me (Me = Ag, Pt) catalysts prepared by depositing the noble metals by electroless plating deposition (EPD) or deposition–precipitation (DP) methods on α-Al2O3 asymmetric ceramic membrane with or without a further surface coating by a carbon thin layer are reported. The effect of the second metal with respect to Pd-only catalysts considerably depends on the presence of the carbon layer on the membrane support. On ceramic membranes ...

Palladium catalysts supported on SO4=-, Cl−-, F−-, and Br−-doped zirconia were tested for the direct synthesis of hydrogen peroxide under very mild (1 bar and 20 °C) and nonexplosive conditions. The catalysts were characterized by thermogravimetric/differential scanning calorimetry analysis, N2 physisorption, and temperature-programmed reduction before and after catalytic tests to investigate the oxidation state of the metal. The catalytic tests were carried out in different solvents, and the effect ...

All samples have been characterized by N2 physisorption, ion chromatography and thermal analysis coupled with MS analysis of evolved gases (EGA). The samples possessed high specific surface areas and mean pore size in the mesopore range. TG/DSC/EGA analysis allowed us to observe all phenomena related to the calcination process ...

A series of new tubular catalytic membranes (TCMs) have been prepared and tested in the direct synthesis of H2O2. Such TCMs are carbon-coated asymmetric α-alumina mesoporous membranes supported on macroporous α-alumina. Pd was introduced by deposition–precipitation to obtain an even Pd particle distribution inside the membrane pore network. This type of membrane was active in the direct synthesis of H2O2. Catalytic tests were carried out in a semi-batch recirculating reactor under very mild conditions. ...

Tubular catalytic membranes (TMCs) active in the direct synthesis of hydrogen peroxide were prepared, characterized, and tested using methanol as the reaction medium. Low hydrogen peroxide selectivity was found when only palladium was used as a catalyst, whereas palladium/platinum bimetallic samples gave higher productivity and selectivity, with an optimum molar ratio of 18. The H2O2 decomposition rate is influenced by the feed gases. O2 improves H2O2 stability, whereas H2 causes hydrogen peroxide ...

Ga2O3-promotion of ZrO2/SO4 (SZ) systems has been shown to influence the catalytic activity of n-butane isomerization. This contribution reports a study on the influence of Ga2O3 addition and of calcination temperature on ZrO2 structure, morphology and activity. Small additions of Ga2O3 (1–5 mol%) bring about an increase of specific surface area (SSA). By N2 physisorption, X-ray diffraction, Raman spectroscopy and TEM microscopy, the increase of an amorphous phase and the decrease of SSA were observed ...

Such TCM's are asymmetric α-alumina mesoporous membranes supported on macroporous α-alumina, either with a subsequent carbon coating (CAM) or without (AAM). Pd was introduced by two different impregnation techniques. Deposition–precipitation (DP) was applied to CAM's to obtain an even Pd particles distribution inside the membrane pore network, whereas electroless plating deposition (EPD) ...

Abstract A single step sol–gel reaction starting from Zr alkoxides, in water–propanol mixtures, was employed to obtain ZrO 2 –SO 4 powders; sulphuric acid was used both as the sulphating agent and as the catalyst of the polycondensation reaction in the gel formation. The water/alkoxide ratio and the acid catalyst amounts were varied in the starting mixtures. Samples prepared by using nitric acid as the reaction catalyst and subsequently impregnated with sulphuric acid were also obtained for the sake ...

We describe a patient with structurally normal heart who developed hemodynamic instability during orthotropic liver transplantation caused by severe dynamic left ventricular outflow tract obstruction. Successful management of this adverse event was facilitated by the use of intravenous terlipressin. The case highlights a role for terlipressin as a selective vasopressin receptor agonist with subsequent effects on systemic vascular resistance.
