Many commercial processes are available for the removal of H2S from gaseous streams. The desulfurization of gas streams using aqueous ferric sulfate solution as washing liquor is studied. Apart from sulfur, only H2O is generated in the process, and consequently, no waste treatment facilities are required. A distinct advantage of the process is that the reaction of H2S with is so rapid and compl...

She, Hongyun, Shigang Xiong, Min Lin, Ebrahim Zandi, Cecilia Giulivi, and Hidekazu Tsukamoto. Iron activates NFB in Kupffer cells. Am J Physiol Gastrointest Liver Physiol 283: G719–G726, 2002; 10.1152/ajpgi.00108. 2002.— Iron exacerbates various types of liver injury in which nuclear factor (NF)B-driven genes are implicated. This study tested a hypothesis that iron directly elicits the signalin...

Acceleration of the autoxidation of Fe2+ by apotransferrin or apolactoferrin at acid pH is indicated by the disappearance of Fe2+, the uptake of oxygen, and the binding of iron to transferrin or lactoferrin. The product(s) formed oxidize iodide to an iodinating species and are bactericidal to Escherichia coli. Toxicity to E. coli by FeSO4 (10(-5) M) and human apotransferrin (100 micrograms/ml) ...

biofabrication by using fungi is an exciting recent interest to develop an eco-friendly production of metallic nanoparticles (nps) for pharmaceutical applications. this study aimed to synthesize and characterize gold (au) and silver (ag) nps by using penicillium simplisimum. the fungus was grown in fluid czapek dox broth on shaker at 28 ºc and 200 rpm for ten days. then the supernatant was sepa...

The quest for early detection and treatment of diseases has led to intense research on theranostics [1]. With diagnosis and therapy combined onto a single platform, theranostics enables real-time monitoring of the status of disease treatment and allows for timely adjustment of type and dose of drugs, paving the way towards personalized medicine. The unique physiochemical properties of nanoparti...

Sickle erythrocytes have increased ferritin and increased molecular iron on the inner membrane leaflet, and we postulated that cytosolic labile iron is also elevated. We used the fluorescent metallosensor, calcein, and a permeant Fe2 chelator to estimate labile cytoslic Fe2 , and calcein plus an Fe3 chelator to estimate total cytosolic labile iron (Fe2 Fe3 ). We measured membrane nonheme iron b...
