  2020-04-16

  

  The assessment process is even more difficult when Commercial-Off-The-Shelf (COTS) components – whose internals are partially or totally unknown – come into play. COTS are being increasingly used by the industry to reduce costs and to shorten development (and possibly deployment) time. However, sinc

  For the first time, we provide evidence for COMT Val158Met modulation of long-term fear extinction in humans, evident both in cortical (LPP) and autonomic (fear bradycardia) components of the conditioned fear response. We further found that the initial acquisition of fear is related to dispositional

  2020-04-16

  

  Recently, several Pt(IV) complexes as prodrugs have been designed and studied to enhance anti-tumor efficacy of traditional Pt(II) drugs, improving their cellular uptake and blood-circulation time [26], [27], [28], [29]. Compared with their Pt(II) counterparts, six-coordinated Pt(IV) complexes with

  With regards to what might represent a typical “baseline” ChE (or AChE) activity in Saccostrea sp., it Lithium Citrate should be remembered that the observed enzyme responses were obtained in laboratory exposures, over a narrow experimental window (96h), with specimens collected over the course of a

  A similar pattern was observed for both tissues of P. harpagos, evidencing the absolute predominance of acetylcholinesterase. As observed, no effects were attributed to Iso-OMPA. The hypothesis that the major cholinesterasic form is AChE was reinforced considering the higher hydrolytic activity, whi

  2020-04-15

  

  Another enzyme class that has emerged as a potential alternative to P450s are the so-called ‘unspecific peroxygenases’ (UPOs). They also contain a heme but are extracellularly expressed fungal enzymes that are often more stable than P450 monooxygenases. Importantly, UPOs use H2O2 instead of O2 as th

  2020-04-15

  

  The in vitro enantioselective metabolism of pesticides has been investigated by employing human liver microsomes, which are a reliable resource to perform MCL enantioselective risk assessment in humans (Carrão et al., 2019; de Albuquerque et al., 2018, 2016; Yao et al., 2016). The enantioselective m

  Materials and methods Results Discussion Natural compounds and their derivatives have been investigated as candidates for the treatment of bone diseases and can also be the sources of nutraceutical agents and therapeutic agents [28]. Using peptides as therapeutic effects on bone-related dis

  2020-04-15

  

  In normal cells, the apoptotic stimuli lower the expression level of antiapoptotic proteins by increasing turnover rate and preventing the constant degradation of proapoptotic proteins. Thus, the dysregulation of anti-/pro-apoptotic proteins will confer the survival of cancer (±)-Baclofen via enhan

  Another question concerns the mechanism of PC reduction during the phosphate starvation response. There are at least three main mechanisms of PC depletion: suppression of PC synthesis due to substrate exhaustion, downregulation of PC synthase expression by suppression of gene transcription or intens

  2020-04-15

  

  A major open question in the field of lipid mediators is the molecular nature of the PLA2 enzyme involved in the release of DHA and related omega-3 fatty acids from phospholipids as a first committed step for the generation of SPMs. Although by analogy with AA it is often assumed that cPLA2α may ser

  2020-04-15

  

  Imatinib (STI-571) is a first-line tyrosine kinase inhibitor (TKI) targeted at breakpoint cluster region-Abelson kinase (ABL) for the treatment of chronic myeloid leukemia (CML) [26]. As a type II inhibitor, imatinib achieves significant selectivity by binding to an inactive DFG-out conformation (DF

  ER redox imbalance leads to the accumulation of misfolded proteins, which might trigger the unfolded protein response (UPR) [17]. In the initiation of UPR, GRP78 preferentially binds to unfolded proteins, shifting the binding equilibrium away from IRE-1, PERK, and ATF-6, the initiators of UPR [18].

  Haggar et al. reported the synthesis of two new series of 8-(2-imino/oxo/thioxo pyrimidin-4-yl)-4-methyl-6-nitro-2-oxo-2H-chromen-7-yl benzoates 56 (X=O, S, NH) and 8-(pyrazol-3-yl)-4-methyl-6-nitro-2-oxo-2H-chromen-7-yl benzoates 57 [Y=C(O)CH3, 2,4-(NO2)2C6H3]. The 8-acetyl-4-methyl-6-nitro-2-oxo-2

  2020-04-14

  

  Assessment of DNA damage by comet assay and ChEs activity has been widely used as a biomarker of genotoxicity and exposure to pesticide respectively, to measure the risk related to pesticides in the exposed population [15]. Very few studies have explored the association between DNA damage and worker
