- An aluminium alkoxy-hydride compound of formula Al(OR)aHb (I) is new. In (I), R = 3-10 C alkyl or 5-8 C cycloalkyl; a = 1 or 2; b = 1 or 2; and a + b = 3. Also claimed are: (i) a process for the prodn. of (I) by reacting an Al hydride (II) with an ...
stage50. Quantification by qPCR on genomic DNA or qRT-PCR on total RNA indicated that the deletion of exons 9 and 10 reached 95 % in follicular B cells (FoB) fromCD21-Cre HellsF/Fmice and was almost complete inMb1-Cre HellsF/FFoB (Supplementary Fig.2b, c). Even though mutant B c...
so as to decrease the hysteresis of the mixture. The process for the preparation of this copolymer comprises a method of grafting the complex polyether block in three stages: i) functionalization of the ends of living polymer chains by a cyclic organosiloxane compound, in order to form a livin...
concentrated and recrystallized using ethanol, yielding 88% OHB (Fig.1), the purity of which was determined by TLC. The aluminium 60F-254 base of the thin layer chromatography plates (10.0 cm ×

From these, thick sections were cut, washed (pH 7.4), fixed, dehydrated in an ethanol series, mounted on aluminium slabs and sputter-coated in gold. For the SEM, samples were examined using a Cambridge Instruments S600 Scanning Electron Microscope operating at 7.5 v. A further set of samples...
(2013) demonstrated that ROS production induced by ethephon, an ethylene-releasing compound, was mitigated by exogenously applied GSH in sweet potato [22,23]. Furthermore, ethylene signalling was involved in the stimulation of GSH synthesis in aluminium (Al)-exposed A. thaliana plants [24]. ...

of an element analogous to tellurium, which we can describe as dvi-tellurium, Dt having an atomic weight of 212, and the property of forming the oxide DtO3. If this element really exists … Dvi-tellurium is, of course, polonium. To date, only PoO and PoO2 have been prepared. ...
