Copper hydroxide nanowires were synthesized from copper chloride dihydrate and sodium hydroxide in the presence of Pistachio leaf extract at room temperature. The results of scanning electron microscopy (SEM) exhibited that the copper hydroxide Cu(OH)2 are nanowires in shape and having an average diameter of ca. 10 nm and lengths of up to 500 nm . The Fourier transfor infrared spectroscopy (FT-IR) results examined the bioactive functional groups , which acts as dispersing, binding and capping agent for the copper hydroxide nanowires. X-ray diffraction (XRD) spectra confirmed the copper hydroxide nanoparticles crystalline in nature. The current research introduces a new, simple, and rapid route for the in - laboratory synthesis of copper hydroxide nanowires. This facile and green approach may provide a useful tool to large scale synthesis other copper nanoparticles that have potential biotechnology. © 2015 VBRI Press. Source

Recent advances in molecular genomic analysis showed the possibility of resolving the unexplained mysteries and problems of various biological phenomena. DNA methylation is one of three molecular epigenomic mechanisms involved in controlling gene expression during the process of cellular differentiation, development and aging. This genomic phenomenon has become of great interest in applied research of molecular medicine for its participation in development of various diseases. There is much evidence of possible connection between genomic DNA methylation profiles and psychiatric disorders. Recent studies have demonstrated possible role of DNA methylation in schizophrenia, depression, suicide and bipolar disorder. Aberrations in DNA methylation of several promoter regions of genes have been identified in the genomes of patients with psychiatric disorders. The aim of this effort is to review research work and looking into possible link between abnormal DNA methylation in genomic DNA and psychiatric disorders. © 2010 Academic Journals Inc. Source

DNA methylation is one of three epigenetic mechanisms which has seen increasing interest among cancer researchers, as changes in DNA methylation have emerged as one of the most consistent molecular aberrations in various neoplasms. Aberration of DNA methylation have been identified in the global genomic DNA (hyper or hypo methylation) or within CpG islands in promoter regions of tumor suppressor genes. Several types of bacteria which cause chronic infections are associated with cancer development and chronic infection of Helicobacter pylori might give rise to changes in pattern of DNA methylation. Recent discoveries are giving evidence in the involvement of aberration in DNA methylation in conferring resistance to antitumor agents and efforts of molecular biologists are directed to overcome this problem by introducing new epigenomic drugs which reform DNA methylation and help in tumor therapy. Another interesting prospective of current research in DNA methylation is the possibility of development molecular markers for early detection of tumors. The objectives of this study are to review various recent progress of DNA methylation in cancer research. © 2010 Academic Journals Inc. Source

Due to the commercial value of phosphate rock (PR) as a fertilizer precursor, it is necessary to investigate its heavy metals content. Chromium (Cr) may present as Cr(III) or Cr(VI) in PR; but quantitative differentiation between them is not an easy task. This is due to possible interconversion of Cr species during the digestion/leaching process. In this work, ultrasound digestion (USD) of PR was optimized (300 mg PR, 4.0 mL of 4.0 mol L-1 nitric acid, 15 min sonication) for the sake of leaching Cr species prior to their determination by flame atomic absorption spectroscopy. Using multi-walled carbon nanotube (MWCNT) as adsorbent, solid phase extraction (SPE) was used to separate Cr(III) from the digestate at pH 9, while total Cr was estimated after reducing Cr(VI) into Cr(III). The optimum USD/SPE method gave LOQ and LOD of Cr(III) of 0.96 mg kg-1 and 0.288 mg kg-1, respectively. The method sensitivity was 1.44×10-3 AU kg mg-1 within the studied Cr concentration range (5-400 mg kg-1). The USD/SPE method was validated by analyzing lake sediments LKSD-4 certified reference material, and by comparison with classical digestion method (CD). Application of USD/SPE on Jordanian PR samples gave total Cr rang 29.1-122.0 mg kg-1 (±1.4-6.3), while Cr(III) ranged between 23.8 and 101.7 mg kg-1 (±1.3-5.5). AFPC Rock Check Program samples gave total Cr range 238.9-394.7 mg kg-1 (±11.5-24.1), while Cr(III) ranged between 202.4 and 335.8 mg kg-1 (±11.4-18.3). These results were very close to the results obtained by the CD method. © 2013 Elsevier B.V. Source

The IJERA project is aiming at strengthening capacities of the Environment Monitoring and Research Central Unit at The Royal Scientific Society (EMARCU/RSS) in Jordan while realizing it as an international centre of excellence, and reinforcing the cooperation capacities and research activities in Jordans water sector by defining water research priorities to respond to socio-economic needs, facilitating participation in European water research initiatives and inclusion in Euro-Mediterranean Research and Innovation Area. The specific objectives of IJERA project are: EMARCUs Cooperation Capacities Reinforcement, Water-Related Research Results Dissemination, Internationalization and Coordination between Research and Business Sectors, Enhancement of EU-Jordan S&T Partnerships in Water Research,Capacity Building for Solving Specific Water Issues, EMARCUs Strengthening,Setting Up Jordans Environmental NCP The project thus addresses current Work Programme for International Cooperation to reinforce the cooperation capacities of research centres located in the ENP countries and contributes to the European international co-operation in science and technology strategy implementation, while strengthening the international dimension of the ERA and improving the framework conditions for international S&T cooperation. The main impact of IJERA will be increased capacities of the EMARCU centre and the structuring and enhancement of the existing EU-JO support landscape in the domain of Water S&T cooperation through a threefold way: (i) by supporting the participation of Jordan in the FP7 in water research area, (ii) knitting together all relevant support schemes, and (iii) facilitating both the uptake of common identified water research areas and the monitoring of the performance and impacts of this cooperation. The IJERA consortium brings together 4 Jordanian and EU organisations representing a well-defined mix of competencies and expertise.
