Modulation of catalase, copper and zinc in the hippocampus and the prefrontal cortex in social isolation-induced depression in male rats

depression in socially isolated people is not fully understood. In this study, we hypothesized that fourteen days of social isolation would lead to a reduction in zinc and copper levels and catalase activity in the hippocampus and prefrontal cortex that may contribute to the occurrence of depression. The prefrontal cortex is a brain region often investigated in psychiatric illnesses (Vostrikov et al., 2007). The hippocampus is also of particular importance for studying depressive and anxiety behavior

ZINC AND LEAD IN AQUATIC PLANTS AND BOTTOM SEDIMENTS OF ANTHROPOGENIC RIVERS

more than in the associated water [5, 26]. Thanks to this feature macrophytes are often more useful in the environment controlling than direct analysis of water and sediments [18]. They can also be used in heavy metal removal from a variety of sources. Literature data indicate [23], there is a clear tendency to accumulate certain trace elements in plants. It is formed in the following way: –cadmium – a high degree of accumulation, –zinc, copper and lead –an average degree of accumulation

HIGH SENSITIVITY METHANE SENSOR BY CHEMICALLY DEPOSITED NANOCRYSTALLINE ZNO THIN FILM

Nanocrystalline n-ZnO thin films were deposited on SiO2-coated (0.45 μm) p type Si substrates (10-20Ω-cm) by a low cost chemical deposition technique to fabricate ZnO-based resistive sensors for methane detection. The nanocrystalline ZnO needle like structures were grown on RCA cleaned p-Si substrates by successive immersion (100-200 times) into a Sodium Zincate bath (0.125M) kept at room temperature and DI water maintained at 90 oC . The Sodium Zincate was prepared by reacting Zinc Sulphate

Study of Acid Phosphatase in Solubilization of Inorganic Phosphates by Piriformospora indica

Phosphorus is an essential plant macronutrient present in the soil. Only a small portion of phosphorus in soil is taken up by plants and the rest of it becomes unavailable to plants as it is immobilized. Phosphate solubilizing microorganisms play a vital role in converting the insoluble form of phosphates to the soluble form. The present paper reports the solubilization of tricalcium phosphate, rock phosphate, single super phosphate, zinc phosphate and aluminum phosphate by Piriformospora

EFFECT OF ANNEALING ON GAS SENSING PERFORMANCE OF NANOSTRUCTURED ZnO THICK FILM RESISTORS

ZnO nano-particles have been synthesized by simple chemical route using a starting solution consisting of zinc acetate and citric acid as a surfactant agent. The structural properties of the prepared ZnO nano-particles annealed at different temperatures have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses. The XRD patterns show ZnO-wurtize phase in the nano-powders, and size of crystals increases by increasing the annealing temperatures. The TEM

Nanocrystalline ZnO based MEMS Gas Sensors with CMOS ASIC for Mining Applications

In this paper a nanocrystalline (nc) zinc oxide based hybrid gas sensor with signal conditioning ASIC has been reported for sensing and transmitting the information about methane concentration from the underground coalmine environment. A low power, low temperature nc zinc oxide MEMS based gas sensor has been designed, fabricated and tested for the purpose with a power consumption of ~70mW and sensitivity of 76.6 % at 1.0% methane concentration at a sensor operating temperature of 1500C. For

BACTERIAL METALLOTHIONEINS

Heavy metals are found in all living organisms where, as indispensable microelements (e.g. zinc, iron, copper), are involved in endless metabolic processes. However, living organisms are also at a risk of exposure to highly toxic metals, including cadmium or lead, which do not play any physiological role. Among multiple mechanisms associated with the maintenance of micronutrient homeostasis and detoxification of unwanted metals, there is a family of low-molecular-weight, cysteine-rich proteins

Wavelet Transform Smoothing Filters for Metal Oxide Gas Sensor Signal Cleaning

This paper reports on a series of experiments to evaluate the methods for feature extraction and denoising the digital signal from thin film zinc oxide-tin dioxide composite gas sensor devices. The aim was to find a method that not only cleaned the signal but also maintained the shape, precision and resolution of the signal. It was found that the Savitzky–Golay smoothing filter method gave the best, smoothed and cleaned, approximation of the sensor response regardless of the thin film

SYNTHESIS OF ZnO NANORODS BY HYDROTHERMAL METHOD FOR GAS SENSOR APPLICATIONS

ZnO nanorods with different sizes and shapes have been successfully synthesized via a simple hydrothermal route, using zinc acetate and Cetyltriammonium bromide (CTAB) as the reactants. The thick films of as prepared ZnO were prepared by screen-printing technique in desired pattern. The films are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The gas sensing properties of the materials have been investigated for various

Reproduction and life history traits of a resistance breaking Globodera pallida population

-germinated in the dark at room temperature before transferring the sprouting tubers into a well-lit room for shoot hardening. Hatching assay Cysts of both G. pallida populations Oberlangen and Chavornay were incubated in potato root diffusate (PRD), Zinc Chloride (ZnCl2), or tap water (H2O). The hatched J2s were counted weekly for a period of eight weeks. PRD was obtained from the susceptible potato cv. ‘Desiree’ grown in the glasshouse for a period of three weeks. The plants were uprooted and roots
