This paper is devoted to determining whether the addition of geological information can improve resource estimate mineral resources. The geochemical data used come from 116 drill holes in Nkout East iron deposit southern Cameroon. These are modeled on Surpac and Isatis softwares represent 3D distribution deposit. Statistical analysis then a variographic study performed spatial variability iron....

The indolo[2,1- b]quinazoline alkaloid tryptanthrin has previously been identified as the cyclooxygenase-2 (COX-2) inhibitory principle in the extract ZE550 prepared from the medicinal plant Isatis tinctoria (Brassicaceae). We here investigated the potential inhibitory activity of tryptanthrin and ZE550 on COX-2, COX-1 in cellular and cell-free systems. A certain degree of selectivity towards C...

Phytoextraction is gaining great attention as an alternative technique for remediation of heavy metal contaminated soils. A greenhouse study was conducted to assess heavy metal (Cd, Pb, and Zn) accumulation in three weed species viz., Avena sterils, Isatis tinctoria and Xanthium strumarium. A range of phytoavailable Cd, Pb and Zn concentrations in soils was created by applications of five diffe...
