Palmaria palmata (Dulse) is a red seaweed that may be a potential protein source in the human diet. Its protein content, amino acid composition, and protein digestibility were studied with algae collected every month over a 1-year period. Significant variations in protein content were observed according to the season: The highest protein content (21.9 +/-(More)
The proximate composition of pulp, skin and seeds of prickly pear cactus (Opuntia ficus indica) was investigated and is reported on a dry weight basis. The most abundant component of the pulp and skin was ethanol-soluble carbohydrates. Pulp contained glucose (35%) and fructose (29%) while the skin contained essentially glucose (21%). Protein content was(More)
Phycoerythrin is a major light-harvesting pigment of red algae and cyanobacteria widely used as a fluorescent probe. In this study, phycoerythrin of the red macroalga Palmaria palmata was extracted by grinding the algal sample in liquid nitrogen, homogenisation in phosphate buffer and centrifugation. Phycoerythrin was then purified from this crude extract(More)
BACKGROUND A 776C-->G variant (dbSNP ID: rs1801198) in the transcobalamin gene (TCN2; MIM# 275350) decreases the cellular and plasma concentration of transcobalamin and thereby influences the cellular availability of vitamin B(12). OBJECTIVE To evaluate the worldwide prevalence of this variant and its association with homocysteine plasma level. METHODS(More)
Blood glucose (BG) and plasma insulin (IRI) were measured during two breakfasts different only by the nature of proteins--egg (E) or ham (H)--in eight normal subjects. Compared with H, E led to a flattened BG response at 30, 40, and 50 min and to a sustained BG from 150 to 240 min. Integrated BG response was not significantly different between E and H.(More)
The circadian and ultradian variations of blood glucose and plasma insulin have been characterized individually and as a group phenomenon in five healthy young adults studied while adhering as closely as possible to their usual routine of sleep, activity, meal content and timing. Three complementary methods were used to analyze the data: displaying raw data(More)
Palmaria palmata (dulse) is an edible red alga constituting a potential protein source in human diet. However, previous studies showed that the digestibility of dulse proteins is bad because of the cell-wall encapsulating cytoplasmic proteins and the presence of fibers. The water-soluble xylan, present in high proportions in dulse, could be involved to(More)
BACKGROUND Moderate hyperhomocysteinemia is a risk for neural tube defect and neurodegenerative and vascular diseases and has nutritional, metabolic, and genetic determinants. Its prevalence in sub-Saharan Africa remains unknown. OBJECTIVE Our goal was to evaluate the prevalence of hyperhomocysteinemia and the influence of nutritional, metabolic, and(More)
Blood glucose, plasma insulin and glucagon, as well as pancreatic insulin, glucagon and somatostatin contents, were measured in control (C group, 18% casein), deprived (D group, 5% casein) and pair-fed (PF) rats at seven intervals during 23 wk after weaning (wk 0). In C rats, plasma and pancreatic insulin showed parallel variations, in D rats, plasma(More)
The authors report on the observation of a woman treated with isoniazide, who presented clinical symptoms of hypoglycemia during treatment (seating, confusion, anxio-depressive syndrome, lipothymia). After the antitubercular treatment was stopped, a moderate hypoglycemia without clinical manifestations accompanied by a marked hyperinsulinemia and normal(More)
