Strongylocentrotus purpuratus embryos were fractionated into two cell populations of defined lineages at times corresponding to two critical developmental events: determination (16-cell stage) and early differentiation (mesenchyme blastula). The 16-cell stage blastomeres, labeled with [35S]methionine, exhibited identical protein synthesis patterns by fluorography, and this pattern was not signi...

The pattern and schedule of histone synthesis in unfertilized eggs and early embryos of the sea urchin Strongylocentrotus purpuratus were studied using two-dimensional gel electrophoresis. After fertilization there is an abrupt change in the pattern of histone variant synthesis. Although both cleavage-stage (CS) variants. However, after fertilization, both CS and alpha messages are translated. ...

The aim of antenna array synthesis is to achieve a desired radiation pattern with the minimum number of antenna elements. In this paper the antenna synthesis problem is studied from a totally new perspective. One of the key principles of compressive sensing is that the signal to be sensed should be sparse or compressible. This coincides with the requirement of minimum number of element in the a...

Red pine leafs were applied for the green method preparation of MgO nano-plates. The MgO nano-plates were used for the one-pot synthesis of dihydropyrano [3,2-c] chromene derivatives. This procedure is very simple and affords excellent yields. MgO nanoplates were synthesized via a simple precipitation method with the using of an extract solution of red pine leaves. The XRD pattern shows a cubic...

Bromodeoxyuridine incorporation is a useful method for studying the pattern of DNA synthesis in proliferating cells. The distribution pattern of incorporated BrdU in villus enterocytes of duodenal explants was analysed after exposure to TNFalpha in organ culture. TNFalpha caused a consistent, low level uptake of BrdU in the portion of the nucleus close to the nuclear membrane, this pattern was ...

Objective(s): In recent years, green synthesis of nanoparticles is under exploration due to wide medicine and biological applications and research interest in nanotechnology. Green synthesis of zinc oxide nanoparticles (ZnO NPs) is becoming increasingly importance as eco-friendly. The objectives of this study were the production of zinc oxide nanoparticles using pars...

The rate of protein synthesis through the cell cycle of Schizosaccharomyces pombe has been determined from the incorporation of pulses of [3H]tryptophan in synchronous cultures prepared by selection in an elutriating rotor. This selection procedure caused minimal perturbations as judged by asynchronous control cultures, which had also been put through the rotor. The rate of synthesis showed a p...

This paper presents a logic synthesis tool called BETSY (BIST Environment Testable Synthesis) for synthesizing circuits that achieve complete (100%) fault coverage in a user specified BIST environment. Instead of optimizing the circuit fo r a generic pseudo-random test pattern generator (by maximizing its random pattern testability), the circuit is optimized for a specific test pattem generator...
