Light and electron microscopy were used to analyse the process of interaction of Streptococcus agalactiae (serotypes Ia, III, and V) with resident and activated mouse peritoneal macrophages. Transmission electron microscopy showed that adherence of the S. agalactiae serotype Ia, but not III and V serotypes, to the surface of activated macrophages triggers(More)
A study of several pathways of carbohydrate and ketone bodies metabolism was carried out in Atlantic salmon (Salmo salar) to assess the basal metabolism of the brain, and the possible existence of post-feeding changes in brain and liver metabolism. The main results obtained in brain of Atlantic salmon indicate a use of exogenous glucose as a main fuel(More)
The levels of glycogen and glucose, and the activities of several key enzymes of glycogenolysis, glycolysis, gluconeogenesis and the pentose phosphate shunt were assessed in kidneys of rainbow trout (Oncorhynchus mykiss) of two sizes (80 and 140 g) after transfer to seawater (28 p.p.t.) during 7 days. The results indicated changes, mainly size-independent,(More)
RATIONALE Several mutations that impair the development of blood lineages in the mouse also impair the formation of the lymphatic vasculature and its separation from the blood vasculature. However, the basis for these defects has remained unknown because the mutations characterized affect more than one blood lineage. OBJECTIVE We tested the hypothesis(More)
The effect of seawater and brackishwater exposure on gill HCO3(-)-ATPase and Ca2+ dependent ATPase activity in rainbow trout (Oncorhynchus mykiss) was investigated at different periods of time. HCO3(-)-ATPase activity decreased after the transfer to either brackishwater or seawater. Ca2+ dependent ATPase activity decreased during the initial period (1 to 4(More)
Rationale: Several mutations that impair the development of blood lineages in the mouse also impair the formation of the lymphatic vasculature and its separation from the blood vasculature. However, the basis for these defects has remained unknown because the mutations characterized affect more than one blood lineage. Objective: We tested the hypothesis(More)
Two sizes of domesticated rainbow trout (Oncorhynchus mykiss, 40 +/- 0.67 and 180 +/- 3.9 g) were directly transferred to brackish water (9 ppt) and seawater (28 ppt). Kidney Na(+)-K(+)-ATPase and Mg(2+)-ATPase activities were measured in fresh water, and after long-term seawater adaptation (up to 21 days). Renal Na(+)-K(+)-ATPase activity increased after(More)
Readily derived from D-glucose, 5-[(2R,3S,4R)-3,4-dihydroxypyrrolidin-2-yl]-2-methyl-3-furoic esters and amides are selective and competitive inhibitors (K(i)> or = 3 microM) of alpha-L-fucosidase from bovine epididymis and from human placenta.
