174 people studied , 91 were normal controls, 55 nephropathy with renal insufficiency ( CIR ) and 28 without renal failure ( SIR) . The standard test of glucose tolerance (TST ) in 102 , being a definite intolerance in nephropathy , which was greater in the CIR group was performed . The differences between the 3 groups were statistically significant from 90 minutes. The tolbutamide test ( TT ) conducted in 83 subjects showed a decrease with poor resilience in response nephropathy . The curves allow differentiation found curves diabetics. Tolbutamide index also allowed differentiation between the 3 groups . The glucagon test (TG ) conducted in 20 subjects suggests the existence of a normal glycogenolysis in nephropathy , which showed a hyperglycemic response than controls. Relationship between the magnitude of serum creatinine of nephropathy with the degree of abnormality of test glucose ...

The present research study analyses, for the first time, the viability of using thermally activated ichu grass as a supplementary cementitious material for the design of future eco-cements. To this end, the ichu ash resulting from the activation was characterised and its pozzolanic activity, the evolution of its mineralogical phases during the pozzolanic reaction and the physical-mechanical behaviour of the blended cementitious matrices were analysed. The results show that ichu ash exhibited high pozzolanic activity in a pure pozzolan/lime system as a consequence of its high reactive silica content. Conversely, its use in a pozzolan/cement system gave rise to negative effects due to the presence of important alkali contents in the ash (9.6% Na2O eq). The blended cements presented greater water demand, reduced capillary absorption, increased resistivity and lower mechanical properties (10...
