... were collected in the open top chambers of Montar- don and Donon. These plants were placed under controlled conditions of air pollution which were equivalent to the pollution recorded in ... needles of fumigated trees. In the Montardon forest, the terpene composition of IST and LC was indepen- dent of air pollution conditions during...

... which correspond to a half-life of dissociation of 36–105 min [15]. The oxidation of elafin and trappin down-shifts the half-life of there complexes with NE to % 1.3– 1.8 min. On the other hand, the oxidized ... article reports the kinetic consequences of inhibitor elafin and trappin oxidation on their interaction with NE and Pr3. It also examines the effect of insol...

... coincide with the region that binds HR1 upon 6HB formation. The strong affinity of RC-101 for HR2 prevents the inter- action of HR1 and HR2, formation of the 6HB, and subsequent fusion of the host ... regions of gp41 [12]. During 100 days of serial passaging, HIV-1 strain BaL developed three cationic mutations in the presence of sublethal concentrations of RC-101 [1...

The relative contribution of this second kind of element to gene expression is expected to depend on the length of the transcription unit, it being greater in longer ... all along the transcription unit. Among the former, we find the general transcrip- tion factors involved in PIC assembly, initiation and early elongation [4,5]. The mech...

... this region is localized on the tip of the FAD-binding domain, in close spatial proximity to the protein region encoded by exon VIa of the mSMOl isoform. This observation has led us to hypothesize ... correct localization of this isoform within the nucleus. In con- clusion, the mSMOl enzyme needs at least two domains to be nuclear localized. Fig. 2. Stereo representation...
