Considering nutrient delivery and micronutrient use efficiency problems, mesoporous nanosilica (mNs) reduced graphene oxide (rGO)-based iron zinc nanocomposites were formulated. Prepared characterized for FTIR spectroscopy, XRD, FE-SEM, HR-TEM, AAS to examine surface functional groups, morphology, structural composition. XRD spectrum confirmation with SAED image of confirms the polycrystalline ...

The level of the heavy metal in green tiger shrimp (Penaeus semisulcatus) and crab (Portunus pelagicus) caught off the Persian Gulf near Bushehr province were investigated. This study was performed to evaluate instrumental neutron activation analysis (INAA) to analyze heavy metal concentration in crab and shrimp whole body tissue. The order of the swimmer crab and shrimp heavy metal concentrati...

Ion homeostasis plays important roles in development of metabolic diseases. In the present study, we examined the contents and distributions of 25 ions in chicken muscles following treatment with selenium (Se) deficiency for 25 days. The results revealed that in chicken muscles, the top ranked microelements were silicon (Si), iron (Fe), zinc (Zn), aluminum (Al), copper (Cu) and boron (B), showi...

Zinc is a minor micronutrient that also involved in carbohydrate, protein synthesis metabolisms. The present study was carried out to analyze response DNSA, proline, and MDA (Malondialdehit) responses the form of zinc oxide nanoparticles (ZnO NPs) Pisum sativum, for period 21st 35th days. Two P. sativum (Maro Tarım Kars) were used as material presence 0.8 ppm 1.8 ZnO nanoparticulate. length bio...

In the present work, both seawater and limpets (Patella vulgata L.) were collected from different sampling points in the Vigo estuary area (Galicia, NW Spain) and their heavy metal concentrations (Zn, Cd, Pb, Cu) were determined by means of a voltammetric technique. The results showed a direct relationship between the heavy metal levels in seawater and the content in biological samples, especia...

The objective of the present study was to study the effect of zinc supplementation (ZnSO4) on sperm morphometry of the Murrah buffalo bulls. Eight apparently healthy, sexually mature and clinically normal Murrah buffalo bulls of similar body weight and age group (nearly 3.0 to 6.5 years) were randomly divided into two groups: control and ING groups. The Diet for both the groups was the same exc...

Investigations on the accumulation of heavy metals five of the most commercially important fishes in the Parangipettai coastal waters were selected and analyzed for the Zn, Pb, Cr, Co and Cd concentrations in the muscles. The results revealed that the Cr and Zn concentrations were the highest; followed by Pb<Cd<Co being the lowest in the five species of fish tissue. The muscle concentrations of...

The antioxidant enzymes copper/zinc (Cu-Zn) and manganese (Mn) superoxide dismutase (SOD) have been implicated in protection of the lungs from oxidant damage. Mn SOD in particular may be related to acquired tolerance in cells following chronic ozone exposure. In order to study these protective and adaptive phenomena in oxidant injury, the cellular location and relative abundance of Mn SOD and C...

An on-line solid-phase extraction method linked to inductively coupled mass spectrometry (ICP-MS) has been developed for the determination of low levels of uranium and thorium in environmental samples. The hyphenation of lab-on-valve (LOV) and multisyringe flow injection analysis (MSFIA), coupled to an ICP-MS, allows the simultaneous determination of thorium and uranium in different types of en...
