Many papers have been written on the synthesis of gold nanoparticles but very few included pictures of the process, and none of them used video to show the whole process of synthesis. This paper records the process of synthesis of gold nanoparticles using video clips. Every process from cleaning of glassware, an important step in the synthesis of metallic nanoparticles, to the dialysis process ...

Fifteen autochthonous walnut (Juglans regia L.) genotypes of the North-western Himalayan region were evaluated for biochemical composition. The moisture content in them ranged from 2.98 to 8.69 % whereas, oil varied 40.00 62.43 %. linoleic acid was found most abundant among fatty acids values which between 48.50 and 67.30 Furthermore, linolenic oleic 5.70 18.58% 12.14 20.60 protein carbohydrate...

Cadmium (Cd) and selenium (Se) could jointly affect plant growth. To investigate the of Se on Cd accumulation in Juglans regia physiological mechanism by which regulates Cd-induced oxidative stress, this study, effects different foliar application doses (0 (Se0), 20 (Se20), 200 (Se200) ?M) J. (variety Xinfeng) seedlings under stress (5 mM) were determined. The results show that exogenous (Se20 ...

There is some report about the hypoglycemic effect of Juglans rejia L. leaf in alloxan induced diabetic rats and hypoglycemic effect of its fruit peel administered intra peritoneally. Thirty male Wistar rats divided into five groups, to evaluate the hypoglycemic and pancreas β-cells regenerative effects of oral methanolic extracts of leaf and fruit peel of walnut. Rats were made diabetic by int...

The purpose of this work was to provide information on heavy metals concentration in soils and in irrigation water in Thessaly, Central Greece, where tobacco (Nicotiana tabacum) is cultivated. Tobacco tends to accumulate high levels of heavy metals, especially Cadmium. During the years 1998, 1999 and 2000, 795 surface soil samples (0-30 cm depth) and 200 water samples were collected from Kardit...

BACKGROUND Juglans regia has been found to exhibit significant anticancer activity against various human cancer cell lines. This study was undertaken to isolate the active chemical constituent (Juglone) and to investigate its cytotoxic activity along with its various analogs against different human cancer cell lines. METHODS Isolation of juglone, a napthoquinone, from the chloroform extract o...

This Horizontal Standard includes principles and procedures for the determination of trace metals in aqua regia and nitric acid digests of sludge, soil and treated biowaste and neighbouring samples, using atomic absorption spectrometry with electrothermal atomization in a graphite furnace. The method is applicable for determination of low concentrations of the following elements: Ag, Cd, Co, Cr...

Controlled diluted aqua regia addition leads to NIR (near infrared) luminescence from aggregated gold nanoparticles at 916 nm. This turn-on luminescence has been observed for gold nanoparticles, regardless of reductants used in their preparation. These aggregated nanoparticles are nontoxic and have been used for bioimaging in human liver carcinoma cells.

Analysis of genetic structure and differentiation using 12 microsatellite loci of six walnut populations, three each from the Greater Caucasus and the Talysh, revealed a moderate range of variation. The observed number of alleles ranged from 2 to 11 alleles with a mean of 5.6 alleles per locus. The populations differed significantly for the frequency and composition of alleles for ten out of tw...
