  2021-05-07

  

  In general, cellular senescence is considered a programmed response to stress that can be activated by oxidative stress, irradiation or action of substances or drugs. These stressors cause DNA damage and, through the action of specific proteins (p53 and p21), lead to cell senescence (di Fagagna, 200

  In the present work, we have investigated the reactivity of N-aryl-N′-hydroxyguanidines 1a–d (see Scheme 1 for structures) with the water-soluble Cu(II) complex 8. Using EPR and UV–Visible spectroscopy, we have shown that the studied N-aryl-N′-hydroxyguanidines 1a–d can bind and transfer electrons t

  Conclusions In this paper we describe the recombinant expression and characterization of ParI, a C5-DNA-MTase from P. arcticus 273–4. To our knowledge, this is the first characterization of an orphan C5-DNA-MTase from a psychrophilic bacterium. The C5-DNA-MTase could not be expressed in regular E

  Midazolam oral clearance is used for characterization of both intestinal and hepatic CYP3A activity. However, the identification and subsequent use of metabolic markers of CYP3A activity can eliminate the need for unnecessary administration of probe drugs such as midazolam. Such metabolic markers wo

  When a 6-hour delay orexin receptor was implemented for the WRAM, neither of the E2-treated groups (E2-only and E2 + Levo) differed in WMC errors between the postdelay trials and the baseline trials. This suggests that exogenous E2 treatment protected from a delay-induced impairment in performance

  Conventional assays rely on a comparable transformation of the target analytes and the structurally similar (but not identical) proxy substrates and are commonly used to measure individual enzyme activities in (pre-treated) intact sludge flocs (Burgess and Pletschke, 2008a, Gessesse et al., 2003, Yu

  It is believed that emphysema in smokers is mediated by proteases released from inflammatory Gliotoxin mg that cause destruction of the extracellular matrix in alveolar septa [1].

  Both, the kK3 and kK5-mediated ubiquitination leads to rapid internalisation of target proteins followed by lysosomal degradation, similar to that seen for MARCH-1/8 [77]. Ubiquitination activity of kK3 and kK5 depends on the positioning of the targeted lysine (or cysteine) residues [22]. The positi
