  The relatively low overall response rates suggest the need for better predictive markers for response. The patient demographics in the SARC trial did not reflect typical Ewing sarcoma demographics as the patients tended to be older and had primarily soft tissue tumors. In addition, although accrual

  One possibility to differentiate between the two failure modes, and also to identify the corresponding characteristics of the resulting fracture surface, is a series of FNCT measurements with varying nominal (initial) stress. The dependence of the observed time to failure tf on the actual stress cha

  Conformational Activation of APC/C Enables Binding to the Coactivator CDC20 APC/C comes to life by binding a coactivator. This is controlled in part by phosphorylation and APC/C conformational changes that expose the SRT 1720 for the C box and IR tail of the coactivator. In interphase when mitoti

  Regulation of p53 via the ubiquitin-proteasome pathway Studies into regulation of p53 via PTM processes that involve phosphorylation, acetylation, ubiquitination, SUMOylation, neddylation, and methylation are being increasingly reported [23], [24]. Phosphorylation and acetylation of p53 stimulate

  2020-04-09

  

  One step in pyrimidine biosynthesis is conversion of l-dihydroorotate (DHO) to orotate (ORO), under action of the enzyme dihydroorotate dehydrogenase (DHODH, EC 1.3.99.11), which contains a flavine (FMN) as redox cofactor [1]. In this transformation, electrons resulting from DHO oxidation are transf

  2020-04-08

  

  The assembly and maturation of invadopodia can be initiated by chemical stimuli such as the epidermal growth factor (EGF), as well as the mechanical signals from extracellular matrix (ECM). Upon binding, EGF activates the EGF receptor (EGFR), which further activates several intracellular signaling p

  2020-04-08

  

  Widely expressed mammalian adhesion receptors for fibrillar collagens include the α2β1- and α11β1-integrins and the discoidin domain receptors (DDRs), DDR1 and DDR2 (Leitinger, 2011). Integrins and DDRs bind distinct and separate motifs in native fibrillar collagen (Curat et al., 2001, Vogel et al.,

  Several effective strategies have been developed to design activatable MR probes according to the Solomon, Bloembergen and Morgan (SBM) theory, including modulation of the number of inner-sphere water molecules (q), the rotational tumbling time (τ) and the residence lifetime of inner-sphere water mo

  The ADME profile of AAT-008 () was very promising, with high stability in HLM. The pre-clinical pharmacokinetic properties of AAT-008 were also assessed in rats (Sprague-Dawley, male), dogs (beagle, male), and monkeys (cynomolgus, male). The experimentally determined parameters are summarized in . A

  Henderson et al. [20] reported that allergen-induced airway remodeling was blocked by the CysLT1 receptor antagonist montelukast. The development of epithelial thickening and mucus accumulation at relatively small despite was also suppressed by montelukast. The CysLT2 receptor antagonist BayCysLT2R

  Common features of TdT, pol μ and pol λ TdT, pol μ and pol λ remain in a closed conformation throughout their catalytic cycle, contrary to pol β [24•, 53, 54•]. One possible explanation for this observation is that they have traded fidelity (which requires open-to-closed transition) for a very ti
