Inducing high levels of reactive oxygen species (ROS) inside tumor cells is a cancer therapy method termed chemodynamic (CDT). Relying on delivery Fenton reaction promoters such as Fe2+, CDT takes advantage overproduced ROS in the microenvironment. We developed peptide-H2S donor conjugate, complexed with AAN-PTC–Fe2+. The AAN tripeptide was specifically cleaved by legumain, an enzyme overexpres...

The present experiment addressed the effects of different iron (Fe) concentrations in nutrient solution supplied as Fe-HBED, i.e., 0.02 (Fe0, control), 1.02 (Fe1), and 2.02 mmol L−1 (Fe2) on lettuce (‘Nauplus’ ‘Romana’) yield compositional traits. This was carried out a greenhouse using an open soilless cultivation system, at experimental farm University Catania (Sicily, Italy: 37°24′31.5″ N, 1...

Salah satu pencemar yang berbahaya dalam limbah buangan industri yaitu logam berat besi (Fe2+). Banyak teknik pengolahan dilakukan untuk mwnurunkan kadar besi. satunya diantaranya adalah dengan adsorbs. Adsorpsi sering digunakan karena prosesnya sederhana dan efektif mengurangi berat. Penelitian ini bertujuan menganalisis efektifitas karbon aktif kulit singkong sebagai adsorben pada penyerapan ...

fe2+ ion-selective membrane sensor has been fabricated from polyvinyl chloride (pvc) matrixmembrane containing neutral carrier tetra phenyl porphyrin (tpp) ionophore. the addition ofsodium tetraphenylborate (natpb) and the plasticizer dbp has been found to substantiallyimprove the performance of the sensor. the best performance was obtained with the sensor havinga membrane of composition of tpp...

Geometrical frustration of the Fe ions in LuFe2O4 leads to intricate charge and magnetic order and a strong magnetoelectric coupling. Using resonant x-ray diffraction at the Fe K edge, the anomalous scattering factors of both Fe sites are deduced from the (h/3 k/3 l/2) reflections. The chemical shift between the two types of Fe ions equals 4.0(1) eV corresponding to full charge separation into ...

introduction             wastewater treatment using activated sludge process (asp) produces huge amounts of sludge that must be treated by efficient methods. wastewater sludge handling is one of the most important economic-technical challenges of wastewater treatment projects. conventional methods for this purpose are very time consuming, expensive and in lots of cases have limited success. in ...
