MgAl and MgAl/ZnO coatings were prepared by plasma electrolytic oxidation (PEO) of AZ31 magnesium alloy in aluminate electrolyte (5 g/L NaAlO2) without with addition ZnO particles various concentrations. The coating was partially crystallized contained MgO MgAl2O4 phases. to had no significant effect on the surface morphology formed coatings, while Zn content increased particle X-ray diffractio...

The mannitol-lactulose intestinal permeability test was evaluated in 100 healthy controls and 47 patients with Crohn's disease. These patients were further separated into three subgroups of increased activity (Harvey-Bradshaw index) and in two subgroups, with elective colonic lesions and associated ileal and colonic lesions. Results were given as percentages of urinary recoveries for mannitol (...

O'Barr, Thomas P. (Agricultural Research Service, Washington, D.C.). Effect of alanine and threonine on the synthesis of serine by Leuconostoc mesenteroides. J. Bacteriol. 86:1321-1325. 1963.-Growth of Leuconostoc mesenteroides in the absence of serine was inhibited by l-alanine and l-threonine. Varying the glycine concentration when l-alanine was present suggested a direct relationship between...

Brainstem gliomas constitute 10% of brain tumors in children and less than 2% in adults. Since therapeutic options are limited and brainstem gliomas are associated with a high morbidity and mortality, we sought to analyze the prognostic factors associated with a better outcome. We reviewed the records of 86 patients with brainstem gliomas treated between 1996 and 2006. We recorded demographic a...

Leuthardt [1938a] and Bach [1939] have expressed the opinion that in addition to the ornithine cycle there are other mechanisms of urea synthesis in the mammalian liver. Leuthardt [1938a] found that liver of starved guinea-pigs forms urea more rapidly from glutamine than from NH4Cl. He concluded that NH3 cannot be an intermediate in the urea formation from glutamine and that there is a more or ...

Microcomputer virus programs have become a serious problem for users of DOS-based microcomputers. Although the number of viruses in circulation is growing steadily, fewer organizations are being disrupted by infections. Prompt detection of (and effective response to) virus infections is limiting the damage. The prudent course of action for organizations that use DOS-based microcomputers is to i...
