Macroporous chitosan spheres encapsulating superparamagnetic iron oxide nanoparticles were synthesized by a facile and effective one-step fabrication process. Ferro-gels containing ferrous cations, ferric cations and chitosan were dropped into a sodium hydroxide solution through a syringe pump. In addition, a sodium hydroxide solution was employed for both gelation (chitosan) and co-precipitati...

The catalase level of Bacteroides distasonis (ATCC 8503, type strain) varied with the amount of hemin supplied to the medium when the cells were grown in either a prereduced medium containing 0.5% peptone, 0.5% yeast extract, and 1% glucose or in a prereduced, defined heme-deficient medium. The effect of hemin on catalase production could not be duplicated by ferrous sulfate or ferrous ammonium...

This review deals with the layer-by-layer (LbL) assembly of polyelectrolyte multilayers of biopolymers, polypeptides (i.e., poly-l-lysine/poly-l-glutamic acid) and polysaccharides (i.e., chitosan/dextran sulphate/sodium alginate), onto thermo- and/or pH-responsive micro- and nano-gels such as those based on synthetic poly(N-isopropylacrylamide) (PNIPAM) and poly(acrylic acid) (PAA) or biodegrad...

Ciprofloxacin bioavailability may be reduced when ciprofloxacin is co-administered with metallic ion containing preparations. In our previous study, physicochemical interaction between ciprofloxacin and ferrous sulphate was successfully simulated in vitro. In the present work, comparative in vitro ciprofloxacin solubility and dissolution studies were performed in the reactive media containing a...

The present study investigated the biofortification effect of FYM, Zinc and Iron on yield (grain straw q h-1), wheat at harvest. Soil application Two foliar applications (one heading other milking stage) along with 10 t FYM h-1 gave highest grain (53.95 56.95 h-1) (71.86 75.18 for two consecutive years while protein content (12.50 12.63%). Yield straw) significantly increased over control as a ...

Excess iron causes cell injury by reacting with superoxide anions (O2*) and hydrogen peroxide (H2O2) and producing hydroxyl radical (OH*) and reactive oxygen species (ROS). In the present study, albino rats were fed with biscuits enriched with ferrous sulphate (0.3% w/w) for 10 weeks to have overload iron conditions and observed a significant decrease in serum chromium, brain serotonin and dopa...

Objectives: The aim of our study was to compare the effects of intravenous ferrous sucrose versus oral ferrous sulphate on postpartum iron deficiency anaemia. Material and methods: This prospective randomized study was conducted in Obstetrics and Gynaecology Department of Alkhidmat Teaching Hospital Mansoorah Lahore and in the Obstetrics and Gynaecology Department of Akhtar Saeed Trust Hospital...

Spectrophotometric measurements of the Fricke–gelatin–xylenol orange (FGX) gel dosimeter demonstrated reproducible linear dose response up to 25Gy. However, oxidation processes continue post-irradiation, affecting the response of this dosimetry system. Additional oxygenation during preparation increases the sensitivity of the gel but does not improve the auto-oxidation stability of the dosimete...

Biochemical studies on the urine of schizo phrenic in-patients and out-patients have shown the drug rejection rate to vary from 5 per cent. to 32 per cent. in the U.K., U.S.A., and U.S.S.R. (3, 4, 8, 9, II, 12). Even higher rejection rates (70 per cent.) were found with depressed out-patients (12), and high rejection rates have been found in antenatal patients prescribed ferrous sulphate, out-p...

The absorption of iron from Spatone Iron-Plus has been investigated in pregnant women with iron deficiency anaemia. A total of 25 mg Fe was taken and absorption determined from the increase in serum iron concentration during a period of 3 h. Mean absorption was 28%, significantly higher than in nonpregnant, nonanaemic women (14%). These studies demonstrate that Spatone provides an alternative t...
