Genome-wide screening of mitogen-activated protein kinase (MAPK) gene family and expression profile under heavy metal stress in Solanum lycopersicum.

MAPKs are one of the essential signal transduction complexes which are responsible for the perception of abiotic stress and for the producing of related transcripts for responding to abiotic stress. For systematical analyzes of the mitogen-activated protein (MAP) kinase gene families and their expression profiles in Solanum lycopersicum L. exposed to diverse heavy metal stresses, 17 SlMAPK genes were studied in comparison with their 159 orthologs from various plant species.

Method development and validation for determination of N-Nitrosamines in pharmaceutical preparations by LC-MS/MS: Application to extractables and leachables studies.

The use of highly sensitive and reliable analytical methods is essential for Extractables & Leachables studies. Especially the determination of N-Nitrosamines in drugs, which have carcinogenic properties and may contaminate drugs at trace levels, is quite important. In this study, a new, sensitive, short-time and reliable liquid chromatography with tandem mass spectrometry method was developed for the analysis of 15 N-Nitrosamines defined in the European Pharmacopoeia within the scope of Extractables & Leachables studies and validated according to the International Council for Harmonization (ICH Q2 (R2)).

Plant-Endophyte Interaction during Biotic Stress Management.

Plants interact with diverse microbial communities and share complex relationships with each other. The intimate association between microbes and their host mutually benefit each other and provide stability against various biotic and abiotic stresses to plants. Endophytes are heterogeneous groups of microbes that live inside the host tissue without showing any apparent sign of infection.

Multidimensional Scaling of the Mineral Nutrient Status and Health Risk Assessment of Commonly Consumed Fruity Vegetables Marketed in Kyrgyzstan.

Intensive production of fruits and vegetables causes heavy metal accumulation. Consumption of this kind of foodstuff is a growing concern of the modern world with the additional distress of the supply of enough foodstuffs. To contribute to this global purpose, this research aimed to find out the mineral nutrient and heavy metal concentrations of commonly consumed fruity vegetables in Kyrgyzstan.

Environment-Based Impairment in Mineral Nutrient Status and Heavy Metal Contents of Commonly Consumed Leafy Vegetables Marketed in Kyrgyzstan: a Case Study for Health Risk Assessment.

Leafy vegetables are important components of the human diet for providing mineral nutrients. However, due to the tendency of metal accumulation, metal contents of leafy vegetables need not only to be determined but also estimated health risk for revealing possible health effects on humans. The aims of this study are (I) to examine comprehensive concentrations of trace/heavy metals along with some macroelements including Ca, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn in selected leafy vegetables from Kyrgyzstan; (II) to assess recommended dietary allowances (RDA); and (III) to evaluate hazard quotient (HQ) and carcinogenic risk estimation with associated vegetable consumption.

Construction, characteristics and high throughput molecular screening methodologies in some special breeding populations: a horticultural perspective.

Advanced marker technologies are widely used for evaluation of genetic diversity in cultivated crops, wild ancestors, landraces or any special plant genotypes. Developing agricultural cultivars requires the following steps: (i) determining desired characteristics to be improved, (ii) screening genetic resources to help find a superior cultivar, (iii) intercrossing selected individuals, (iv) generating genetically hybrid populations and screening them for agro-morphological or molecular traits, (v) evaluating the superior cultivar candidates, (vi) testing field performance at different locations, and (vii) certifying. In the cultivar development process valuable genes can be identified by creating special biparental or multiparental populations and analysing their association using suitable markers in given populations.

Monodisperse Ag/Pd core/shell nanoparticles assembled on reduced graphene oxide as highly efficient catalysts for the transfer hydrogenation of nitroarenes.

Addressed herein is a facile seed-mediated synthesis of Ag/Pd core/shell nanoparticles (NPs) and their assembly on reduced graphene oxide (rGO) to catalyze the transfer hydrogenation of nitroarenes to anilines using ammonia borane (AB) as a hydrogen donor under ambient conditions. Monodisperse Ag/Pd core/shell NPs with controllable Pd shell-thickness were synthesized by the means of thermal decomposition of palladium(II) bromide over as-prepared Ag NPs in the mixture of oleylamine and oleic acid at 220°C. As-synthesized Ag/Pd core/shell NPs were characterized by TEM, HR-TEM, XRD, XPS, UV-Vis spectroscopy and ICP-MS and then they were assembled on reduced graphene oxide (rGO).

Reduced graphene oxide-supported CuPd alloy nanoparticles as efficient catalysts for the Sonogashira cross-coupling reactions.

Monodisperse CuPd alloy nanoparticles (NPs) were prepared by using a typical high-temperature organic solution phase protocol comprising the coreduction of copper(II) acetylacetonate and palladium(II) acetylacetonate by morpholine-borane complex in oleylamine and 1-octadecene solution at 80 °C. The presented synthesis protocol allows us to control the composition of CuPd alloy NPs by simply tuning the initial ratio of metal precursors and the Cu-rich Cu75Pd25 NPs and Pd-rich Cu32Pd68 were synthesized besides the Cu48Pd52 NPs. Transmission electron microscopy studies revealed that most of the CuPd alloy NPs are polyhedral with an average diameter of 3.
