Pb(II) and Cd(II) biosorption on Chondracanthus chamissoi (a red alga)
Chondracanthus chamissoi is an efficient biosorbent for Pb(II) and Cd(II). The sorption efficiency increases with pH and reaches an optimum around pH 4. Maximum sorption capacity reaches 1.37mmolPbg-1 and 0.76mmolCdg-1. ...
Reactivity of the insecticide chlorpyrifos-methyl toward hydroxy! and perhydroxyl ion. Effect of cyclodextrins
(John Wiley & Sons Ltd, 2009-07)
The reactivity of Chlorpyrifos-Methyl (1) toward hydroxyl ion and the α-nucleophile, perhydroxyl ion was investigated in aqueous basic media. The hydrolysis of 1 was studied at 25° C in water containing 10% ACN or 7% ...
Multifactorial optimization of the decolorisation parameters of wastewaters resulting from dyeing flowers.
(IWA PUBLISHING, 2009-01-01)
This work deals with the treatment of the wastewaters resulting from the process of dyeing flowers. In some local cases for growing flowers near to Medellin (Colombia), wastewater color was found to be one of the main ...
Metal leaching, acidity, and altitude confine benthic macroinvertebrate community composition in Andean streams
Andean streams drain metal-rich bedrock and are subjected to an extreme altitude gradient, which may create highly selective conditions for life. The aim of the present study was to evaluate the combined effects of metals ...

Hydrogen Sulfide Regulates Inward-Rectifying K+ Channels in Conjunction with Stomatal Closure
(American Society of Plant Biologist, 2015-05)
Hydrogen sulfide (H2S) is the third biological gasotransmitter, and in animals, it affects many physiological processes by modulating ion channels. H2S has been reported to protect plants from oxidative stress in diverse ...
Comparative zymographic analysis of metallopeptidase of Leishmania (Viannia) peruviana and Leishmania (Viannia) braziliensis isolates from Peru
American tegumentary leishmaniasis (ATL) in Peru is mainly associated with Leishmania (Viannia) peruviana and L. (V.) braziliensis. These parasites are genetically related, and their characterization as distinct species ...
