Loss of radioactivity to the aqueous phase of conventional extraction procedures has been observed in studies of glyceride synthesis with labeled fatty acids. A method is presented which does not involve washing procedures and by which ...

Catechol oxidase has been solubilized from the particulate fraction of apple peel using Triton X-100, dialysis and butanol extraction. The partially purified enzyme retained activity during lyophilization in the presence of mercaptobenz...

A differential screw drive for microelectrodes is described, that can be used Nike Free Run 5 with skull chambers or with open tissue preparations. The instrument has a coarse movement providing displacement limited only by the length o...

PGF2α or hypertonic (20 per cent) saline followed by oxytocin was used to terminate pregnancy in 160 women between the 10th and 20th weeks of gestation.In the patients treated with PGF2α minor side-effects were reported in about 50 pe...

Vapor pressure and miscibility isotope effects in hydrogen bonded systems are reviewed. It is shown that the changes caused by H/D substitution reflect the molecular structure. Condensed phase isotope effects are therefore suggested to ...

Let T be a linear operator on the space of all m × n complex matrices such that the rank of T(A) is the rank of A whenever the rank of A is k. We show that there are nonsingular m × m and n × n matrices U and V respectively such that...

We introduce concepts of external and internal complexity to analyze the relation between an adaptive system and its environment. We apply this theoretical framework Nike Free Run 2 Canada to the construction of models in a cognitive sy...

A local realistic model is proposed that agrees approximately with quantum mechanics in the predictions about experiments testing Bell's inequalities by measuring polarization correlations of photon pairs emitted in atomic cascades. No ...

Two new triterpenoids namely putranjivanonol, a hydroxy ketone, and putranjic acid, a hydroxy acid, have been isolated from the trunk bark of Putranjiva roxburghii Wall. (Euphorbiaceae) along with friedelin and putranjivadione and a ste...

An inhibitor of cyclin-dependent kinase (CDK) has been well tolerated in Phase Ia clinical trials and is due to enter Phase Ib trials for glomerulonephritis (GN), a group of inflammatory kidney diseases, in autumn 2002. Details of this ...
