'Pseudohypertriglyceridemia' caused by hyperglycerolemia due to congenital enzyme deficiency.
TLDR
A 76-year-old man was found to have a false hypertriglyceridemia due to a 40-fold increased glycerolemia because of a deficiency in glycerol kinase, and the small number of this family's members did not allow to specify the mode of transmission of this genetic trait. Expand
Effect of pH on oligomeric equilibrium and saccharide-binding properties of peanut agglutinin.
TLDR
The conformation and saccharide-binding properties of peanut agglutinin (PNA) depend on pH as studied by analytical ultracentrifugation, fluorescence, circular dichroism, equilibrium dialysis, and absorption spectroscopy, indicating that tryptophanyl residues are more accessible to the ligand in dimeric than in tetrameric PNA.

Characterization of N-linked oligosaccharides of an HLA-DR molecule expressed in different cell lines.
TLDR
Investigation of the N-glycosylation of a molecule of the human major histocompatibility complex (MHC) class II, the HLA-DR antigen, found differences were noticed within the same molecule, showing the importance of the individual peptide backbone for the glycosylations process. Expand
Structural analysis of the carbohydrate chain of glycopeptides isolated from Robinia pseudoacacia seed lectins.
TLDR
Robinia pseudoacacia seeds contain lectins which are closely related and pronase digestion of the dimeric and tetrameric lectins gave glycopeptides which gave oligosaccharide chains which were determined by 1H NMR spectroscopy and carbohydrate determination. Expand
Activation of human B lymphocytes induced by Robinia pseudoacacia lectin in the presence of T cells.
TLDR
Results show that B cells proliferate in the presence of T cells and Robinia lectin and led to their maturation to plasma cells in the same way as PWM. Expand
Chemical characterization of two urinary sialic acid-rich glycopeptides.
TLDR
The present work describes the preparation and characterization of two new sialic acid-rich glycopeptides, which have been prepared from milk and urine and could not originate from serum. Expand
Serum albumin biosynthesis and secretion by resting and lectin stimulated human lymphocytes.
Normal human peripheral lymphocytes, cultured in serum-deprived medium, synthetized and released serum albumin and some glycoproteins into the culture supernatant. With the use of [3H]leucine, it wasExpand
Analysis of HLA-DR antigen glycosylation by serial lectin affinity chromatography.
TLDR
In contrast to murine and guinea-pig Ia antigens, no significant amount of glycopeptides with biantennary structure was found in HLA-DR, and oligosaccharide heterogeneity is found for each alpha 1, alpha 2- and beta-chain described. Expand
Glycosylation of the human erythrocyte glucose transporter is essential for glucose transport activity.
TLDR
Using transport glycoproteins reconstituted in proteoliposomes, kinetic studies of zero-trans influx were performed and it could be concluded that the release of the carbohydrate moiety from the transport glyCoproteins leads to the loss of their transport activity. Expand
Glycosylation of the human erythrocyte glucose transporter: a minimum structure is required for glucose transport activity.
TLDR
Kinetic measurements of glucose equilibrium influx confirm that a minimum glycosidic structure is required for glucose transport activity and suggest that treatment of the same proteoliposomes by a pool of exoglycosidases led to a complete abolition of activity. Expand
