Here, we report the complete genome sequence of Xanthomonas arboricola pv. juglandis 417, a copper-resistant strain isolated from a blighted walnut fruit (Juglans regia L. cv. Chandler). The genome consists of a single chromosome (5,218 kb).

BACKGROUND Contamination of vegetable crops (as an important part of people's diet) with heavy metals is a health concern. Therefore, monitoring levels of heavy metals in vegetables can provide useful information for promoting food safety. The present study was carried out in north-west of Iran (Tabriz) on the content of heavy metals in vegetable crops. METHODS Samples of vegetables including...

Palladium (Pd) electroplating is widely practiced in the manufacture of advanced electronic devices. The Pd(II) present spent solutions treated by cementation with zinc (Zn) metal powder. In order to recover pure Pd from cemented Pd, a process that consisted leaching followed solvent extraction was investigated. For this purpose, experiments using synthesized ionic liquids (ILs) organic and ino...

Several protocols using different treatments (various mixtures of acids at different temperatures for mineralisation) or using several analysis instrumentations were tested with the aim to define the method allowing the analysis of some groups of elements. This study proposes a protocol of sample treatment and analysis permitting in a single batch the determination of 16 elements (Al, As, Ba, C...

ETHNOPHARMACOLOGICAL RELEVANCE The Juglans regia L. leaf has been traditionally used for treatment of diabetes mellitus in Iran. But yet, no controlled human study has determined its efficacy in diabetic patients. The present study was designed to investigate the effects of the Juglans regia leaf extract on hyperglycemia and lipid profiles in type II diabetic patients. MATERIALS AND METHOD To...

A sustainable supply of phosphorus (P) to agricultural soils should maintain soil fertility without jeopardizing the environment. This study analyzed change in P as a function net mass balance, i.e. input minus removal by harvested crop. The available for crops was estimated extracted ammonium lactate at pH 3.75 (P-AL). First, laboratory and pot-trial data showed that P-AL only 68% total P, eit...

Heavy metals in sediments have received increasing attention in recent years, partly because of the growing scientific and public awareness of environmental issues, and partly because of the improvement in the analytical techniques for accurately measuring their concentrations. Trace metal determinations in soils and sediments commonly involve some type of mineral acid extraction (wet oxidation...

Introduction: The 182 Hf– 182 W decay system (t 1/2 =9 My) is useful to date early Solar System processes, notably metal-silicate differentiation [1-10]. Hf-W systematics of refractory inclusions indicate that these objects formed with an initial 182 Hf/ 180 Hf ratio of ~1×10-4 and ε 182 W of –3.47 ± 0.20 [6]. Recent high precision studies revealed negative ε 182 W values relative to CAIs for s...
