    Notes: [Auszug] Since then we have had the opportunity of examining the activity in vitro and in vivo of the relatively insoluble cupric complex of isoniazid : H2O 1 O-Cu +- HO N-JNTH2 a univalent an ion The results now reported (see Table 1) indicate that this complex is highly active. Thus, it might now be ...

    Notes: [Auszug] A third type of papaverine analogue, obtained by opening the isoquinoline ring along the line bb, does not seem to have been investigated (except that a-diethylamino-4-methoxy deoxybenzoin is reported5 to have half the antispasmodic activity of papaverine in an isolated observation), and we now ...

    Notes: [Auszug] It is known1 that hydrazides form stable complexes with copper. The structures (Ha and 116) have been suggested2*3 for the copper complex of (I), and the anti-tuberculous activity of isoniazid has been attributed4, without direct experimental evidence, to the ability of the hydrazide structure ...

    Notes: [Auszug] This report deals with the in vivo action of verazide and directs attention to its prolonged action and potential value in the treatment of tuberculosis. As verazide : ~CO.NH.N:CH OOH3 OCH3 l-isoMcotinoyl-2-veratrylidene hydrazine is an insoluble derivative of isoniazid, it was decided to test ...

    Notes: [Auszug] AFTER my letter on the above subject (NATURE, January 11) had been posted, it occurred to me to investigate to what extent temperature deviations in Egypt are opposite to those in England, and for this purpose I compared the annual mean temperatures at Abbassia (near Cairo) with those for ...

    Notes: [Auszug] I HAVE read with much interest the letters on this subject that appeared in NATURE during last February and March, and also the account of the discussion at the, British Association (NATURE, October 1, 1908), and my only excuse for re-opening the question at this late date is that a point seems ...

    Notes: [Auszug] Consider the following idealized model. An expanding uni-verse with scale factor a = (1 + z)~l oc r2/3 is filled with uniformly distributed sources of radiation, for example smoothly dis-tributed stars or decaying particles, emitting a luminosity density /. Gas with mean density pg absorbs this ...

    Notes: [Auszug] AMONG the suggestions that the Universe is made mainly of invisible material, one of the most predictive is a proposal put forward by Sciama1'2. In this scheme, this 'dark' matter includes neutrinos with a mass of 27.7 ± 0.5 electron volts (about 0.005 per cent of the electron's mass). The ...

    Notes: [Auszug] A new mechanism is described which can create an instability in homogeneous gaseous matter at very low density. When an isotropic background radiation field has, near an electronic resonance (such as the hydrogen Lyman-α line), a spectral feature for which photon occupation number increases ...

    Notes: [Auszug] We have focused on kidney and Wilms' tumours (WT), because both H19 and IGF2 are expressed in developing kidney and because WT occurs 700-fold more frequently in Beckwith-Wiedemann syndrome (BWS) than in the general population5'15. DNA from 11 normal kidneys, as well as 17 WTs from these and other ...
