Zinc oxide nanoparticles (ZnO NPs) are being utilized in an increasing number of fields and commercial applications. While their general toxicity and associated oxidative stress have been extensively studied, the toxicological pathways that they induce in developmental stages are still largely unknown. In this study, the developmental toxicity of ZnO NPs to embryonic/larval zebrafish was invest...

In a 36-d experiment, 32 pigs were depleted of Zn (24 d) using a soy-isolate (basal) diet (17 mg/kg of Zn) and then fed the basal diet (12 d) supplemented with 45 mg/kg of Zn from ZnSO4 (purified zinc sulfate dry powder, ZnSO4.nH2O) or from a Zn amino acid chelate (ZnAAC) to study the effectiveness of these dietary Zn sources in restoring serum and soft tissue Zn concentrations. Concurrently, n...

The objective of this study was to investigate the effects of foliar applications of potassium and zinc on the fruit yield and quality as well as leaf nutrient concentrations of pistachio cv. ‘Chrokeh’. The experiment was conducted based on a completely randomized block design with nine treatments and three replications per treatment. Treatments were three levels of K2SO4 (0, 1 and 2%) and thre...

Microorganisms, such as bacteria, are one of the first targets of nanoparticles in the environment. In this study, we tested the effect of two nanoparticles, ZnO and TiO2, with the salt ZnSO4 as the control, on the Gram-positive bacterium Bacillus subtilis by 2D gel electrophoresis-based proteomics. Despite a significant effect on viability (LD50), TiO2 NPs had no detectable effect on the prote...

The present investigation on the effect of plant spacing and foliar nutrition growth physiological parameters tuberose (Polianthes L.) cultivar Prajwal was carried out in Department Floriculture Landscape Architecture, HC&RI, Tamil Nadu Agricultural University, Coimbatore, Nadu. experiment designed following principle factorial randomized block design with four spacings (S1-25 x 25, S2- 15 20,S...

Bu araştırmada ZnO NP ve ZnSO4’ın etkisine bırakılan Oreochromis niloticus ’un böbrek kas dokularında çinko birikimi karşılaştırmalı olarak incelenmiştir. Balıklar 0. 5, 2.5 5.0 mg/L ZnSO4’ ın ortam derişimlerine 3 15 günlük sürelerle bırakılarak dokularındaki Atomik Absorbsiyon Spektrofotometrik yöntemlerle saptanmıştır. çalışmada balıkların çinkonun ortamdaki Zn derişimi sürenin artmasıyla ar...

D-amino acid oxidase (DAAO) is biotechnologically relevant enzyme that is used in various food and pharmaceutical industries. DAAO from the yeast Trigonopsis variabilis is an important agent for use in commercial applications because of its high activity with cephalosporin C and is reasonable resistant to the oxidants O2 and H2O2 byproducts of reaction. In this study, response surface methodolo...
