background protein-bound toxins such as indoxyl sulfate (is) are not efficiently removed by conventional hemodialysis (hd). objectives to improve the removal of is, we performed an in vitro study to evaluate the effects of high dissolved hydrogen on the dissociation of is from albumin using simulated hd. materials and methods wasted dialysate from peritoneal dialysis was concentrated a hundred ...

background: exposure of the gingival sulcus while controlling hemorrhage is prerequisites for maximizing treatment outcomes of cervical carious lesions and for obtaining quality impressions for the fabrication of indirect restorations with cervical fi nish lines. gingival retraction cords saturated with different chemical agents are widely used for this purpose. the aim of this study was to inv...

Catalytic oxidation of spent sulfidic caustic consist SH- ion or NaHS compound by H 2 O2 in neutral acidic solution to elemental sulphur may provide a convenient and economical method for the control sulphide wastes their associated odors at pulp, paper textile industry. Oxidation sulfide rayon waste hydrogen peroxide was investigated presence ferric sulfate catalyst. Kinetic equations activati...

Uniform metal iron ellipsoidal particles of around 200 nm in length were obtained by reduction and passivation of alumina-coated a – Fe2O3 ~hematite! particles under different conditions of temperature and hydrogen flow rate. The monodispersed hematite particles were prepared by the controlled hydrolysis of ferric sulfate and further coated with a homogeneous thin layer of Al2O3 by careful sele...

an efficient synthesis of polyhydroquinoline derivatives is achieved via hantzsch condensation reaction between aldehydes, dimedone, ethyl acetoacetate and ammonium acetate in the presence of catalytic amount of sfhs in ethanol. this method gives remarkable advantages such as shorter reaction time, simple workup procedure and good to excellent yields. furthermore the catalyst can be recovered c...

The reducing agents, potassium ferrocyanide, beta-mercaptoethylamine, cysteine, reduced DPN, ferrous sulfate, methyl viologen and ascorbic acid caused the expansion in darkness of disks of primary leaf tissue cut from dark-grown bean plants. The reducing agents interacted synergistically with low irradiances of red radiation and additively with high irradiance of red light. Exposure of disks tr...

background: entry of untreated wastewater of wool scouring factories has been associated with many environmental hazards because of high rate of pollution. presently effective treatment methods and reducing the costs of operation and maintenance from treatment units have always been under the attention of this industry owners. the aim of this survey is to present a suitable method for the treat...

Two coagulants, aluminum sulfate and ferric chloride, were tested to reduce natural organic matter (NOM) as a pretreatment prior to polyvinylidene fluoride (PVDF) microfiltration (MF) membranes for potable water treatment. The results showed that the two coagulants exhibited different treatment performance in NOM removal. Molecular weight (MW) distributions of NOM in the tested surface raw wate...

BACKGROUND The objective was to evaluate efficacy and safety of rapid, large-dose intravenous (IV) administration of ferric carboxymaltose compared to oral iron in correcting iron deficiency anemia due to heavy uterine bleeding. STUDY DESIGN AND METHODS In a randomized, controlled trial, 477 women with anemia, iron deficiency, and heavy uterine bleeding were assigned to receive either IV ferr...

In this study, we extracted fucoidan from compressional-puffing-pretreated Sargassum crassifolium by hot water. The crude extract of fucoidan (SC) was degraded by various degradation reagents and four low-molecular-weight (LMW) fucoidans, namely SCO (degradation by hydrogen peroxide), SCA (degradation by ascorbic acid), SCOA (degradation by hydrogen peroxide + ascorbic acid), and SCH (degradati...
