Background Riboflavin (vitamin B2) is an essential component of the basic metabolism, and an important nutritional and growth factor in humans, animals, plants and micro-organisms. It has been widely used in the fields of pharmaceuticals, feed and food additives. The industrial production of riboflavin mostly relies on the microbial fermentation. Designing an appropriate fermentation medium is ...

Platelet-derived growth factors (PDGFs) and PDGF receptors are expressed in brain, where their functions are largely unknown. We tested the hypothesis that PDGFs play a role in promoting the survival of neurons exposed to metabolic and oxidative insults. Exposure of rat and mouse hippocampal cell cultures to glucose-deficient medium or the hydroxyl radical-promoting agent FeSO4 resulted in prog...

In this work, statistical experimental design was applied for the optimization of medium constituents for Gentamicin production by Micromsonospora echinospora subs pallida (MTCC 708) in a batch reactor and the results are compared with the ANN predicted values. By central composite design, 50 experiments are carried out for five test variables: Starch, Soya bean meal, K2HPO4, CaCO3 and FeSO4. T...

Effects of pressure, dewatering time, and sludge cake thickness on the wastewater by hydraulic dehydrator under condition adding CaO FeSO4 were analyzed using response surface method (RSM). It was found that when parameters changed, trends papermaking municipal similar raw with 3% FeSO4. Specifically, increase pressure time promotes effect sludge, thinner is, better effect. The water content ca...

BACKGROUND Iron (Fe) deficiency anemia remains the largest nutritional deficiency disorder worldwide. How the gut acquires iron from nano Fe(III), especially at the apical surface, is incompletely understood. OBJECTIVE We developed a novel Fe supplement consisting of nanoparticulate tartrate-modified Fe(III) poly oxo-hydroxide [here termed nano Fe(III)], which mimics the Fe oxide core of ferr...

Many soil amendments are used to remediate paddy soils polluted with heavy metals, including arsenic (As) and lead (Pb). This study was conducted assess the efficacy of three inorganic amendments, such as calcium carbonate (CaCO3), sulfate (CaSO4), ferrous (FeSO4), on As Pb co-contaminated soils. The were applied alone and/or in combinations compare theirs for stabilization rice growth. In addi...

various aldoximes and ketoximes synthesis of corresponding aldehydes and ketones in the presence of sio2@feso4 nano composite as recoverable nano catalyst and nh2oh·hcl. the sio2@feso4 nano composite system was carried out between 10 to 15 min in oil bath (70-80 °c) under solvent-free condition in excellent yields in addition this protocol can be used for industrial scales. this method offers s...

Neovascularization and hemorrhage are common features of malignant tumors. We wondered whether hemoglobin derived from extravasated RBC deposits heme-derived iron into the tumor, which could modulate the sensitivity of cancer cells to oxidant-mediated injury. A brief exposure (1 h) of 51Cr-radiolabeled breast cancer cells (BT-20) but not colon cancer cells (Caco-2) to hemin (10 microM) or FeSO4...

This experiment was designed to determine whether dietary hemoglobin (Hgb) iron (Fe) could 0271-5317/$ – see fro doi:10.1016/j.nutres.2 4 Corresponding a E-mail address: p sustain normal Fe status in growing rats adequate or deficient in copper (Cu). Forty-eight weanling rats were divided into 3 groups, each consisting of 16 animals. One group was fed a diet containing 40 mg Fe/kg as ferrous su...
