Background & Aim: The purpose of present study was to examine and validate the folk's claim of inhalation of Monechma ciliatum seeds powder by traditional African natives for cold and allergic conditions, so as to formulate a useful therapeutic agent to respiratory tract infections. Experimental: Different extracts were bio-assayed in vitro for their bioactivity to inhibit th...

A novel, simple, sensitive and effective method has been developed for preconcentration of Hg(II) on nano-Fe3O4-DOP-ED solid-phase extraction adsorbent. In this paper, Dioctyl phthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a n...

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Cu2+ in water samples was reported. In this paper, Isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (IIDE) in order to prepare an effective sorbent for the preconcentration and determination of Cu. The sorption capacity of Isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (II...

Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...

Sustainable ecological and environmental development is the basis of regional development. The sensitivity classification of the ecological environment is the premise of its spatial distribution for land use planning. In this paper, a fuzzy matter-element model and factor-overlay method were employed to analyze the ecological sensitivity in Yicheng City. Four ecological indicators, including so...

The amplified fragment length polymorphism (AFLP) assay is an efficient method for the identification of molecular markers, useful in the improvement of numerous crop species. Bulked Segregant Analysis (BSA) was used to identify AFLP markers associated with water-stress tolerance in barley, as this would permit rapid selection of water-stress tolerant genotypes in breeding programs. AFLP marker...
