High levels of albumin, alpha-fetoprotein (AFP), IgG, prealbumin and transferrin have been detected in cerebro-spinal fluid (CSF) of human fetuses between 14 and 25 weeks old. The concentration of each plasma protein in CSF was found to vary during the gestational period in relation to its serum levels and rate of synthesis and as a consequence of a reduced… (More)
Marine invertebrates, such as lobsters and crabs, deal with a widely and wildly fluctuating temperature environment. Here, we describe the effects of changing temperature on the motor patterns generated by the stomatogastric nervous system of the crab, Cancer borealis. Over a broad range of “permissive” temperatures, the pyloric rhythm increases in… (More)
The crustacean stomatogastric ganglion (STG) receives descending neuromodulatory inputs from three anterior ganglia, the paired commissural ganglia (CoGs) and the single esophageal ganglion (OG). In this paper we provide the first detailed and quantitative analyses of the short- and long-term effects of removal of these descending inputs (decentralization)… (More)
Many farmlands are periodically flooded or ponded by excessive precipitation resulting in changes to soil chemical and biochemical properties. In this study, one set (eight treatments with four replications) of field-moist surface soils (0–15 cm) and their air-dried counterparts obtained from a long-term liming experiment were incubated at 30 °C under… (More)
The levels of IgM were measured in sera from mice with different chromosome complements, including 39,XO mice and phenotypically male mice bearing the sex-reversed gene (Sxr) (XX,Sxr/+ and XY,Sxr/+). The mean values of IgM were found to be higher in normal female mice than in the males belonging to two different strains. This is in agreement with the higher… (More)
The levels of beta-trace protein and lysozyme were estimated in amniotic fluids from normal fetuses and from fetuses with neuraltube defects. The values of these proteins in normal amniotic fluids were found to be similar to those detected in fetuses with anencephaly and spina bifida. The levels of lysozyme were shown to be correlated with gestational age.
