This study investigated the relative bioavailability (RBV) of zinc from different sources used as feed additives in ruminant nutrition based on Zn concentration and activity Zn-dependent enzymes lamb tissues. Thirty-two male lambs Improved Valachian breed (three months old) were randomly assigned to four dietary treatments. For 120 days, fed either total mix ration (TMR) providing 29.6 mg Zn/kg...

Pot experiment was conducted at University of Agricultural Sciences, Bangalore, Karnataka, which received five treatments i.e., 0, 5, 10, 15, 20 kg ZnSO4/ha. Among all the Recommended NPK + ZnSO4 @ kg/ha recorded highest mean dry matter yields tomato. The amount zinc extracted by different extractants were in following order as Mehlich-3 - Zn > 0.1 N HCl AB-DTPA 0.01 EDTA DTPA M 1 NH4OAc (pH...

In order to optimize the process parameters of Cd removal in ZnSO4 production and study mechanism reaction, response surface methodology was used arrange experiments analyze optimal conditions, studied using kinetics. The results show that conditions for are as follows: reaction temperature 55 °C, time 13.43 min, zinc powder dosage should be 2.14 times Cd; main effects three variables from larg...

Chronic inflammation and degradation of elastin are the main processes in the development of abdominal aortic aneurysm (AAA). Recent studies show that zinc has an anti-inflammatory effect. Based on these, zinc may render effective therapy for the treatment of the AAA. Currently, we want to investigate the effects of zinc on AAA progression and its related molecular mechanism. Rat AAA models wer...

Zinc oxide (ZnO) nanoparticles (NPs) have been applied in numerous industrial products and personal care products like sunscreens and cosmetics. The released ZnO NPs from consumer and household products into the environment might pose potential health issues for animals and humans. In this study the expression of microRNAs and the correlations of microRNAs and their targeted genes in ZnO NPs tr...

Everted sacs of rat duodenum and ileum were used to study the effect of anions and organic ligands on the absorption of zinc. The uptake per unit weight of tissue was greater in duodenum than ileum, and it was influenced by the Zn concentration and pH of the incubation medium. The Zn uptake from inorganic salts in simple buffered medium varied in the order zinc sulphate greater than zinc chlori...

We previously generated transgenic C3H/HeN mice by introducing the Escherichia coli O6-methylguanine-DNA methyltransferase (MGMT, DNA-O6-methylguanine:protein-L-cysteine S-methyltransferase, EC2.1.1.63) gene, ada, attached to the Chinese hamster metallothionein I gene promoter. One transgenic mouse line expressing both ada-specific mRNA and Ada protein could be propagated over many generations ...

Zinc deficiency is not only the cause of low productivity of crops, but it also results in low zinc content in seeds, which leads to poor dietary zinc intake. To study the effect of zinc foliar application on improving plant yield and seed zinc content for human consumption, chickpea plants were raised in refined sand culture with deficient (0.2 μM) and sufficient (1μM) supply of zinc under gla...

Ferric iron reductase was purified from magnetotactic bacterium Magnetospirillum (formerly Aquaspirillum) magnetotacticum (ATCC 31632) to an electrophoretically homogeneous state. The enzyme was loosely bound on the cytoplasmic face of the cytoplasmic membrane and was found more frequently in magnetic cells than in nonmagnetic cells. The molecular mass of the purified enzyme was calculated upon...

Flocculation is one of the principal steps in biodiesel production from microalgae. Eight different flocculants were analysed for their efficiency of flocculation of marine microalga, Nannochloropsis oculata. Maximum flocculation was observed as 93.80 and 87.33% with FeCl3 and Fe2(SO4)3 at a concentration of 0.4 and 0.6g/L respectively at 180min. Zinc salts achieved second maximum efficient flo...
