  Yet, the standards fall back on the development process with justification. As shown by Littlewood and Strigini (1993), the extent to which the reliability of software (both OTS and bespoke) can be proved by testing is severely limited––not because appropriate tests cannot be devised, but because ad

  2021-04-23

  

  In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B. An

  Acknowledgments Significance The mechanisms underlying the adverse effects of Epo-stimulating agents on the reduced survival of cancer patients are not well understood. Here, we identified EphB4 as an alternative Epo receptor, which triggers Src/Stat3 signaling via EphB4. We also showed that r

  2021-04-23

  

  Within the X1CX3PX5RX7 motif of several prokaryotic FGE substrates, the residues of X3, X5, and X7 are variably found as mixtures of alanine, glycine, threonine, or serine residues [26], [27]. The docked model of our identified HCTPRRP motif revealed that position X1 (H1) and position X7 (P7) were n

  2021-04-23

  

  We not only found that the ISR leads to attenuation of conventional cap-dependent translation with no change in RAN translation of the G4C2 expanded repeat, but also that GA translation from the expanded repeat (but not from 5 G4C2 repeats, perhaps because the protein product does not aggregate) is

  2021-04-22

  

  Mitochondrial depolarization induced by DHODH inhibition (Figure 5A) may also contribute to the selective effects of DHODH inhibitors on KRAS mutant cells. If so, the effect may arise more from pro-apoptotic effects of mitochondrial depolarization (Lemasters et al., 1998) than from impaired oxidativ

  According to these results, the power GaN seems more robust than existing technologies (VDMOS, Superjunction, IGBT,) [5,10] and [11]. Comparing with the SiC technology, the previous works show a low SEE tolerance [[12], [13], [14]] and [15]. The SOA of power GaN devices can be equivalent to the IGBT

  2021-04-22

  

  In humans, individual differences in prefrontal dopamine are partially caused by the Val158Met single-nucleotide polymorphism on the catechol-O-methyltransferase gene (COMT). This gene controls activity of the COMT enzyme, which degrades extracellular catecholamines including dopamine. The Val varia

  The effect of transformation of the linker Y between the carboxylic Hydroxy Bupropion mg residue and the phenyl moiety of 2b was also investigated, and is illustrated in Table 5. Analogs 2b, 16, and 17, possessing conformationally restricted carboxylic acid residues, tended to show stronger antagon

  Given the fact that most criticism on genetic association studies is the lack of replicability (Hirschhorn, Lohmueller, Byrne, & Hirschhorn, 2002), the aim of the present study is to investigate the influence of the DBH polymorphism rs1611115 (C-970T) on RD in two independent samples of healthy part

  The mesolimbic dopamine system is believed to be highly important for evaluating environmental stimuli in order to generate an adaptive behavioral response. Thus, not surprisingly these functions appear to have been highly conserved across the vertebrate subphylum. Even though teleost fish lack midb
