The reduced activity of glucose-6-phosphate dehydrogenase (D-glucose-6-phosphate; NADP+ 1-oxidoreductase; G6PF) in Mediterranean erythrocytes explains the precarious equilibrium of the hexose monophosphate pathway (HMP) and the susceptibility of these cells to haemolytic agents. G6PD-deficient erythrocytes, in steady-state conditions, have a low NADPH/NADP+(More)
The present paper reports the incidence from 1965 to 1979 of acute hemolytic anemia for a total of 948 cases in G-6-PD-deficient subjects due to the ingestion of fresh or dried fava beans or certain drugs and to viral infections. The highest percentage of hemolytic crises was due to fresh fava beans (94.4%). No cases of favism were observed in breast-fed(More)
Glucose 6-phosphate dehydrogenase (G6PD) activity was assayed quantitatively in red cells from 100 consecutive G6PD-deficient newborn male babies born in a city hospital in Sassari, Sardinia. In four cases G6PD activity was between 30% and 45% of normal: these appeared on electrophoresis to be identical with G6PD Seattle-like. In 65 cases G6PD activity(More)
BACKGROUND Increased intestinal lactase activity has been shown to occur in alloxan and streptozotocin diabetic rats. OBJECTIVE The objective of this study was to determine whether increased intestinal lactase activity is present in humans with diabetes mellitus. DESIGN We assessed the capacity to digest lactose by measuring breath-hydrogen production(More)
A few studies have reported an increased prevalence of Helicobacterpylori (HP) infection in diabetic subjects, which may be one of the causes of gastrointestinal symptoms and chronic atrophic gastritis frequently seen in diabetes of long duration. We determined the prevalence of HP infection in children and adolescents with Type 1 diabetes mellitus (T1DM)(More)
Red cells of G6PD (D-glucose-6-phosphate:NADP+ 1-oxidoreductase; G6PD) deficient (Mediterranean variant) subjects were studied during a fava bean haemolytic crisis. Two representative cases are described. In Case 1, haemolysis was still going on. In more than 50% of the red cells the Hb was confined to one part of the cell, leaving the other part as(More)
This paper describes a laboratory study to choose an appropriate frequency weighting network for predicting the annoyance caused by the noise from small, medium, and large weapons. The results indicate that the annoyance of all three weapon types is the same if the blasts are heard at identical A-weighted SEL's. On the other hand, equal C-weighted SEL's(More)
The last stage of fetal development and the neonatal period represent the most critical phases for the mammals' offspring. In the dog, the knowledge about the final intrauterine fetal development and biology, as well as about the neonatal physiology, remains scarce. Hormonal changes occurring in the last intrauterine fetal phase and during the early(More)
