AbstractAbstract
[en] The National Tritium Labelling Facility (NTLF) is a multipurpose facility engaged in tritium labeling research. It offers to the biomedical research community a fully equipped laboratory for the synthesis and analysis of tritium labeled compounds. The design of the tritiation system, its operations and some labeling techniques are presented

AbstractAbstract
[en] The essential nature of rapid radiotracer synthesis very early in drug discovery programs has driven the need for better and more varied tritium incorporation methods. This review presents a summary of recent advances for tritium introduction via tritiated water, tritium gas, complex tritides, and a range of recently improved tritiation reagents. Access to a wider range of tritiated reagents (for tritioacetylation, tritioformylation, methlylation, etc.) and commercial manifolds for the transfer and use of tritium gas is also discussed

AbstractAbstract
[en] The synthesis of tritiated farnesyl pyrophosphate with high specific activity is reported. trans-trans Farnesol was oxidized to the corresponding aldehyde followed by reduction with lithium aluminium tritide (5%-3H) to give trans-trans [1-3H]farnesol. The specific radioactivity of the alcohol was determined from its triphenylsilane derivative, prepared under very mild conditions. The tritiated alcohol was phosphorylated by initial conversion to an allylic halide, and subsequent treatment of the halide with tris-tetra-n-butylammonium hydrogen pyrophosphate. The hydride procedure followed in this work has advantages over existing methods for the synthesis of tritiated farnesyl pyrophosphate, with the possibility of higher specific activity and a much higher yield obtained. 10 refs., 3 figs

AbstractAbstract
[en] The anomalous Ward identities for flavour U3 x U3 are shown to allow a wide range of values for the quark mass ratio msub(s)/m, but only if there is considerable violation of SUsub(3.currents) symmetry in the vacuum. The consequences are discussed for radiative decays of the eta and eta'

AbstractAbstract
[en] The predominant effect of thermal atom irradiation on solid molecules is saturation of their aromatic functions. Only low level of tritium exchange is observed for aliphatic solids. In contrast, liquids whose frozen surface can be rendered somewhat mobile at appropriate temperatures exhibit more exchange than addition. The rank order of effectiveness of several metals in promoting exchange/addition appears similar to the rank order for heterogeneous catalytic hydrogenation. 3 refs., 8 figs

AbstractAbstract
[en] Modified phase-shift analyses of pp scattering are presented at psub(I)=1.25 and 1.66 GeV/c and shown to give large negative elastic effects in Δsigmasub(L)sup(tot). Using a combination of phase-shift analyses from low energies up to 1.66 GeV/c and simple models of both elastic (pp→pp) and inelastic (pp→NΔ) scattering it is concluded that the measured behaviour of Δsigmasub(L)sup(tot) is mostly inelastic, but the large negative value of Δsigmasub(L)sup(tot) is predominantly elastic with fluctuations produced by inelastic effects. No evidence for a dibaryon resonance is found. (Auth.)

AbstractAbstract
[en] It is stated that recent theories which unite weak and electromagnetic interactions provide new hope for a unified theory of fields and their interactions. Experimental developments such as the discovery of neutral currents and the new psi particles lend encouraging support for some of the ideas embodied in these theories. (author)
