Due to high efficiency and low cost, hydrate-based desalination is investigated as a pretreatment method for seawater desalination. To improve the formation rate of hydrates, effect sodium dodecyl sulfate (SDS) on CO2 hydrate from 3.5 wt.% NaCl solution was measured at 275 K 3 MPa. X-ray diffraction (XRD) cryo-scanning electron microscopy (cryo-SEM) were used measure crystal structure micromorp...

Porphyria cutanea tarda (PCT) is characterized biochemically by excessive hepatic synthesis and urinary excretion of uroporphyrin I. Clinical evidence has implicated iron in the pathogenesis of PCT. The synthesis of the normally occurring isomer of uroporphyrin, namely uroporphyrin III, from porphobilinogen (PBG) requires two enzymes; uroporphyrinogen I synthetase and uroporphyrinogen III cosyn...

Objective(s): Iron is an essential element for living organisms. Iron overload can have detrimental effects on health. This study pertains to the protective role of berberine against ferrous sulfate-induced hepatic and renal functional disorders and histological damages in rats.Materials and Methods: The rats were divided into four groups (n=7): Sham, Ber (10 mg/kg/day for 14 days, by gavage), ...

Magnetofection is a nanoparticle-mediated approach for transfection of cells, tissues, and tumors. Specific interest is in using superparamagnetic iron oxide nanoparticles (SPIONs) as delivery system of therapeutic genes. Magnetofection has already been described in some proof-of-principle studies; however, fine tuning of the synthesis of SPIONs is necessary for its broader application. Physico...

BACKGROUND Although ferric pyrophosphate is a promising compound for iron fortification of foods, few data are available on the effect of food matrices, processing, and ascorbic acid on its bioavailability. OBJECTIVE We compared the relative bioavailability (RBV) of ferrous sulfate in an experimental form of micronized dispersible ferric pyrophosphate (MDFP) in a wheat-milk infant cereal give...

desferroxamine (desferal) is used tochelate iron in thalassemia, a disease of very high prevalence in various parts of lran. we have investigated intestinal zinc absorption in desferal-treated rats which, in pilot experiments, showed low serum levels of both iron and zinc. intraperitoneal administration of ten 0.5 g doses of desferal (one injection every other day) to male rats produced severe ...

Phosphate binders, such as iron （III） citrate hydrate （FCH）, are essential medications for hemodialysis patients. Some in vivo studies have demonstrated that FCH prevented induction of oxidative stress the presence transferrin. However, how affects iron-related absence transferrin remains unclear. In current study, we investigated effects ferric （FC） on vitro to address this question. Human U93...

background: ferrous sulfate is the most used supplement for treating anemia, but it can result in unfavorable side effects. nowadays, nanotechnology is used as a way to increase bioavailability and decrease the side effects of drugs and nutrients. this study investigates the effects of nanoparticles containing iron on blood and inflammatory markers in comparison to ferrous sulfate in anemic rat...

Both alkylarylalkynes and diarylalkynes 1 are converted into the α-diketones 2 in good yield by the use of mercuric salts, e.g., mercuric nitrate hydrate or mercuric triflate, in the presence of water. Other mercuric salts, e.g., sulfate, chloride, acetate, or trifluoroacetate, do not provide the diketone product. A possible mechanism is proposed.

Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...
