Dopamine (DA) and noradrenaline (NA) contents were determined in the areas of the brain directly related to such behaviours (hippocampus, striatum and amygdala). An acute dose of(More)
A direct 2 stage enzymatic test and the direct anti gamma globulin test were used to predict hemolytic disease of the newborn. Maternal allo-antibodies were determined in cord blood of all newborns from April to June 1988. 0.25% bromelase was used for the 2 Stage Enzymatic Test and a polyspecific anti-gammaglobulin serum was used for the Anti Gamma Globulin(More)
Dilute acid hydrolysis (DAH) and auto-hydrolysis (AU) have demonstrated to be optimal pre-treatments for the generation of biofuels from wood. Recent studies have highlighted the importance of ensuring the accessibility of cellulose enzymes during the enzymatic hydrolysis (EH) of pre-treated materials. In this work, the microscopic and nanoscopic structures(More)
The antigen pattern pertaining to the ABO (A, B, AB, O (H)), Rh (D, C, c, E, e), Duffy (Fya and b), Kell (K, k) and MNS (M, N) systems were determined in 144 patients between 1 and 74 years of age who had leukemia, lymphoma or myeloma. An association of phenotype Fy (a-b+) with acute lymphatic leukemia and phenotype NN with chronic myeloid leukemia was(More)
