Radioactive precursors are not incorporated into deoxyribonucleic acid in viva until 18 hours after partial hepatectomy (1,2). This lag period may represent the time required for the synthesis of some specific protein which enables DNA synthesis to occur (3). It is known that inhibitors of protein synthesis will inhibit the synthesis of bacteriophage DNA if they are added before DNA synthesis b...

in this study, the susceptibility of twenty-nine tomato varieties to broomrape infection under glasshouse conditions was investigated. results showed that differences in susceptibility to infection were significant among tomato varieties. significant differences were in number and time of broomrape shoots emerging, broomrape dry weigh (shoots and tubercles) and growth and fruit yield of tomato....

Description OpenMath and MathML are two ways of representing mathematical objects. Semantically, OpenMath is a superset of (content) MathML. The aim is to build a translator from OpenMath to content MathML, using presentation MathML where necessary as in the example of rank in Section 5.3 on MathML OpenMath is extensible, the translator will need to be. There is no a priori choice of implementa...

Olindias sambaquiensis, known as agua viva, is an endemic hydromedusa that is distributed from latitude 23 degrees to 42 degrees south in the southwestern Atlantic Ocean and is known to cause severe stings. This is the first report of the use of vinegar in disarming O sambaquiensis nematocysts and includes preliminary observations on its use in managing the stings of hydromedusae.

The addition of millimolar concentrations of n-butyrate to tissue culture media has been shown to cause a dramatic buildup of the acetylated l -aminolysine forms of cellular histones, without causing cell death (Riggs, M. G., Whittaker, R. G., Neumann, J. R., and Ingram, V. M. (1977) Nature 268,462-464). We find that n-butyrate acts by strongly inhibiting histone deacetylation, without any appa...
