background : microbial monitoring of aquatic sources is essential in the correct management of these vital sources. multiple tube fermentation (mtf) technique is currently used for assessment of the microbial quality of water sources. however, today enzymatic assay has been presented as an alternative approach for detecting indicator bacteria. the purpose of this study was to compare enzymatic ...
such as the process of cellular respiration, which is scavenged by enzymatic and non-enzymatic antioxidant systems. Intake of antioxidants from food sources has always been considered in nutrition research. Therefore, the aim of the present study was to investigate antioxidant effects of crocin on the expression profile of genes involved in the enzymatic antioxidant systems in muscle cells. Ma...
Salinity stresses act as inhibitor factors of plant growth. They can change the physiological characteristics and limit the production of crops. Sodium nitroprusside (SNP) is a stable free radical which use as a signalling molecule in plants and participates in various plant’s physiological, biochemical and molecular processes and also in plant’s responses to environmental stresses. We investig...
the elm leaf beetle xanthogaleruca luteola müller (coleoptera: chrysomelidae), is a serious pest of elm (ulmus spp.) throughout iran. in the present study, lethal and sublethal effects of neem, achook® containing 0.03% azadirachtin, were assessed on mortality, growth, larval weight and feeding deterrence as well as enzymatic and non-enzymatic activities of third instar larvae of the elm leaf be...
In this article, we report on a food-cholesterol monitoring sensor based on a non-enzymatic approach. Amorphous and single-crystal gold electrodes were modified with an alkanethiol self-assembled monolayer to quantify it by voltammetry. We first discuss the basic characteristics of these sensors and provide more information about the instrument developed by JSK Co. This instrument is a battery-...
The preparation of NiCo2 S4 (NCS) nanosheets on photolithographically patterned platinum electrodes by electrodeposition was explored. The as-prepared nanosheets were systematically characterized by field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy techniques. The NCS-modified Pt electrode was used as a non-enzymatic glucose ...
