Synthesis, biological evaluation, and modeling of a C,D-seco-taxoid
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
A C,D-seco-paclitaxel derivative 12 was prepared and tested for biological activity. The key step in the synthesis was a free radical fragmentation of the bicyclic tertiary alcohol 7 under the conditions of the hypobromite ...
Synthesis, biology, and modeling of a C-4 carbonyl C,D-seco-taxoid
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
A C,D-seco-paclitaxel derivative 26 was prepared from taxine and tested for biological activity. Chemical reactivity of the seco-compounds proved to be substantially modified, with respects to taxoids. The corresponding ...
Development of GFP-based high-throughput screening system for directed evolution of glucose oxidase
(Elsevier, 2019)
Glucose oxidase (GOx) mutants with higher activity or stability have important role in industry and in the development of biosensors and biofuel cells. Discovering these mutants can be time-consuming if appropriate ...
Pruning effect on content of quercetin and catechin in berry skins of cv. blaufränkisch (vitis vinifera L.)
(Turkiye Klinikleri Journal of Medical Sciences, 2010)
The effect of pruning severity on quercetin and catechin content in berry skins of cv. Blaufränkisch (Vitis vinifera L.) was studied over 3 years. Different crop levels and canopy structures were obtained by retaining 8, ...
Tribological characterisation in dry sliding conditions of compocasted hybrid A356/SiCp/Grp composites with graphite macroparticles
(Springer London, 2019)
The influence of SiC microparticles reinforcement and graphite macroparticles addition on the friction and wear characteristics of A356 Al-Si alloys, produced by compocasting, has been assessed using a pin-on-disc tribometer. ...
Sensitivity analysis of the variational model for the particulate expansion of fluidized beds
(Taylor and Francis Inc., 2020)
Fluidization experiments were performed by using spherical and non-spherical particles to examine the sensitivity of the variational model to three input parameters: Umf, εmf and Ut. Several correlations for Umf, εmf and ...
Simulation and experimental study of maskless convex corner compensation in TMAH water solution
(Iop Publishing Ltd, Bristol, 2014)
Maskless etching with convex corner compensation in the form of a LT 100 > oriented beam is investigated using both experiments and simulations. The maskless convex corner compensation technique is defined as a combination ...
An ab initio study of SbH2 and BiH2: The Renner effect, spin-orbit coupling, local mode vibrations and rovibronic energy level clustering in SbH2
(Academic Press Inc Elsevier Science, San Diego, 2016)
We present the results of ab initio calculations for the lower electronic states of the Group 15 (pnictogen) dihydrides, SbH2 and BiH2. For each of these molecules the two lowest electronic states become degenerate at ...
Structural Properties of the Multiwall Carbon Nanotubes/Poly(Methyl Methacrylate) Nanocomposites: Effect of the Multiwall Carbon Nanotubes Covalent Functionalization
(Wiley, Hoboken, 2017)
The structural characteristics of polymer nanocomposites with functionalized multiwall carbon nanotubes (MWCNTs) in poly(methyl methacrylate) matrix have been studied in relation to nanofiller loading and surface functionality. ...
Molecular and cytogenetic changes in multi-drug resistant cancer cells and their influence on new compounds testing
(Springer, New York, 2013)
Multi-drug resistance (MDR) is a major obstacle to successful cancer treatment. Therefore, in vitro models are necessary for the investigation of the phenotypic changes provoked by cytotoxic agents and more importantly for ...
