Addition of the four deoxyribonucleosides in vitro to 6C3HED mouse ascites tumor stimulates 32P incorporation into DNA and depresses incorporation into RNA at concentrations greater than 10~4 M. The four ribonucleosides stimulate incorporation into both DNA and RNA. Hydroxyurea blocks the ribonucleoside stimulation of 32P incorporation into DNA but not RNA. The inhibition of 32P incorporation i...

Nanoporous carbon films were deposited by 248 nm pulsed laser ablation of a graphite target in different background pressures of argon (PAr). The morphology changed from smooth, high-density amorphous carbon films at PAr = 20 mTorr to ultra-low density nanoporous material at PAr = 380 mTorr. Subsequently, the nanostructural, chemical and electrical properties of metal containing nanoporous carb...

The author discusses the experience of 'being invaded' that is sometimes communicated by certain severely disturbed patients. The complaint can sometimes be couched in terms of bodily suffering and such patients may state that they have the experience of a 'foreign body' inside. It is suggested that these patients have suffered severe early failure of containment of their projections, while at ...

To test this hypothesis, we have investigated the incorporation of radioactive inorganic phosphate into these phospholipids by rabbit brain slices. If the biosynthesis proceeds as formulated, I --f II + III, the following results can be predicted. Before equilibration of the labeled phosphorus, the phosphate groups in position 4 of II and positions 4 and 5 of 111 must have a higher radioactivit...

This paper proposes a semantics for incorporation that does not require the incorporated nominal to form a syntactic or morphological unit with the verb. Such a semantics is needed for languages like Hindi where semantic intuitions suggest the existence of incorporation but the evidence for syntactic fusion is not compelling. A lexical alternation between regular transitive and incorporating tr...

In this paper, we present a critique of the uniform treatment of nominal and adverbial quantification in van der Sandt’s binding theory of presuppositions. We develop an alternative account of adverbial quantification framed in terms of Beaver’s reconstruction of Karttunen’s satisfaction theory. This account provides a simpler characterization of adverbial quantification that does not require r...

Using selenomethionine to phase macromolecular structures is common practice in structure determination, along with the use of selenocysteine. Selenium is consequently the most commonly used heavy atom for MAD. In addition to the well established recombinant techniques for the incorporation of selenium in prokaryal expression systems, there have been recent advances in selenium labelling in euk...

This review discusses recent developments in the field of nanosized biomaterials and their use in tissue regeneration approaches. The aim is to provide an overview of the research focused on nanoparticle-based strategies to stimulate regeneration. In particular, nanoparticles improve the regenerative capabilities of biomaterials offering ways to control surface and mechanical properties. Moreov...

To define a model for enzyme latency in vitro, the capture was studied of egg white lysozyme by liposomes (phospholipid spherules in the smectic mesophase). Gel filtration resolved liposomes formed in the absence of enzyme from free enzyme when both were chromatographed immediately after mixing. In contrast, if liposomes were swollen in the presence of lysozyme, subsequent chromatography disclo...
