The myristoylated, alanine-rich C kinase substrate (MARCKS) is a prominent substrate for protein kinase C (PKC) in a variety of cells, and has been implicated in diverse cellular processes including neurosecretion, fibroblast mitogenesis, and macrophage activation. In macrophages that have spread on the substratum, MARCKS has a punctate distribution at the cell-substratum interface of pseudopod...

Because of the massive amount of incoming visual information, perception is fundamentally selective. We are aware of only a small subset of our visual input at any given moment, and a great deal of activity can occur right in front of our eyes without reaching awareness. While previous work has shown that even salient visual objects can go unseen, here we demonstrate the opposite pattern, where...

GDANSK, Poland (A P) — Solidarity ch ief Lech W alesa re tu rned to a joyful hom ecom ing yesterday after m ysteriously disappearing for m ore than a day following his release from 11 m onths in martial-law custody. There was no im m ediate explana­ tion for Walesa’s delay in com ing hom e to the first-floor apartm ent in this Baltic port city w here his wife, seven children and hundreds of fri...

The objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. In a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. This time indicates the basal response of vestibular end-organ. After caloric irrigation, pulsed signal was applied for each...

A radioimmunoassay has been developed for Somatomedin B, a growth hormone-dependent factor that stimulates DNA synthesis in human glia-like cells. The sensitivity permits detection of this factor in human plasma diluted 1: 20,000 and in monkey plasma diluted 1: 5,000. It is not measurable in nonprimate plasma diluted 1: 20. The concentration in growth hormone-deficient adult patients is equival...

An investigation has been made of the changes in the major phosphorus containing substances in Avena sativa during the first 8 days of dark germination. The endosperm, roots, and shoots were analyzed separately for acid soluble-P, phytic acid-P, inorganic-P, lipid-P, nucleic acid-P, and protein-P. Phytic acid-P comprised 53% of the total seed phosphate, while the sum of lipid-P, nucleic acid-P ...

Developmental patterns of glyoxylate cycle and photosynthetic activities have been correlated with electrophoretic profiles of cotyledonary RNA and protein in both light- and dark-grown cucumber seedlings (Cucumis sativus L.) Cytoplasmic rRNA increases 10-fold between days 0 and 5, and the steepest increase coincides with the most rapid rise in activities of the glyoxysomal enzymes, isocitrate ...
