The microenvironment of the central nervous system is important for neuronal function and development. During the early stages of embryo development the cephalic vesicles are filled by embryonic cerebrospinal fluid, a complex fluid containing different protein fractions, which contributes to the regulation of the survival, proliferation and neuro-genesis of(More)
During limb outgrowth, Shh, Fgf4, and Fgf8 act as signals controlling limb growth and patterning. Because these genes are expressed in the limb bud and other known signalling centers, we have explored the relationships between the expression of these during mouse development using double in situ hybridization. Within the node and limb bud the expression(More)
Supernumerary chromosomes (B chromosomes) occur in approximately 15% of eukaryote species. Although these chromosomes have been extensively studied, knowledge concerning their specific molecular composition is lacking in most cases. The accumulation of repetitive DNAs is one remarkable characteristic of B chromosomes, and the occurrence of distinct types of(More)
The 5S ribosomal DNA (rDNA) sequences are subject of dynamic evolution at chromosomal and molecular levels, evolving through concerted and/or birth-and-death fashion. Among grasshoppers, the chromosomal location for this sequence was established for some species, but little molecular information was obtained to infer evolutionary patterns. Here, we(More)
We studied protein synthesis, lipid synthesis and CO2 production by oxidation of glycine, alanine and leucine by slices of rat hippocampus during the period of brain growth spurt. The metabolism of the three amino acids decreased with the age of the animals. A major reduction was observed in protein synthesis, which was 4 times higher at 7 days of age than(More)
