  Discussion This study characterized longitudinal changes of cholinesterase and PON1 enzyme activities in greenhouse workers over two periods of a crop season with different levels of pesticide exposure. Although study participants were not exposed to OP insecticides, because they worked under int

  Cytochrome P450 monooxygenases Cytochrome P450 monooxygenases (P450s) belong to one of Nature’s most versatile group of enzymes for C–H functionalization and are able to perform challenging regioselective and stereoselective activations of remote, unactivated C(sp3)–H bonds, for which there are o

  2020-09-25

  

  Introduction Glucose is the major carbon source in most organisms. Cancer Rp-8-Br-PET-cGMPS in particular require a steady source of energy to maintain growth and proliferation, and preferentially use glycolysis for their energy supply even under aerobic conditions. Glucose uptake in mammals is mai

  Materials and methods Results Assay of botulinum toxin activity is critical for the risk-assessment, diagnosis, and treatment of botulism cases. The frequently encountered active forms of the toxin are; L chain (inside intoxicated neuronal cells), BoNT (in the blood stream of a botulism patient,

  For statistical analysis, the Statistical Package for Social Sciences (SPSS) was used (version 21.0; SPSSInc., Chicago, IL). Chi-square (x2) exact test was used for the comparison of categorical data, whereas Wilcoxon and Mann–Whitney U tests were used for the analysis of nonparametric variables bas

  2020-09-25

  

  Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In

  2020-09-25

  

  The Inhibitor of APoptosis (IAP) proteins were first identified as gene products of baculovirus that inhibited apoptosis of infected insect KL 001 (Clem et al., 1991, Crook et al., 1993). Subsequently, the mammalian IAP family was identified (Rothe et al., 1995, Uren et al., 1996). All members of t

  2020-09-25

  

  Programmed cellular death or apoptosis is a process genetically controlled that plays an important role in cellular homeostasis, being an important defense mechanism to remove cells that have been infected, damaged or mutated (Smith and Smith, 2012, Wlodkowic et al., 2011). Nevertheless, apoptosis s

  2020-09-25

  

  ICT is a product of icariin via the metabolism of intestinal bacteria with estrogen-like activities [33]. ICT as a bone-protecting agent can enhance osteoblast differentiation while suppressing osteoclastic differentiation in vitro [19], and stimulate osteogenic differentiation and inhibit adipogene

  Keeping the cofactor content, oligomeric state, subcellular localization, and membrane association in view, DHODH has been broadly divided into two classes, class 1 and class 2 [26], [27]. In many species it is present to either cytoplasm (Class 1) or to the inner mitochondrial membrane (or plasma m

  Introduction Biocatalysis can be used to synthesize chiral building blocks, such as monomers for polymer materials, and precursors for pharmaceuticals [[1], [2], [3], [4]]. Enzymes are very suitable for catalyzing reactions with high enantioselectivity to obtain chiral products. For instance, alc

  On the other hand, the IL-8 promoter activity induced by the signalling cascade of the CysLT1-G300S receptor is higher than that of the WT receptor. The chemokine IL-8 is mainly involved in the recruitment and activation of neutrophils and we have previously shown that this chemokine gene is a targe
