We used mesocarp layer extract of Cocos nucifera and was assessed for the synthesis of silver nanoparticles.

The reduction of silver ions occurred when silver nitrate solution Selleck PU-H71 was treated with aqueous extract of C. nucifera coir at 60 degrees C. Synthesized silver nanoparticles (AgNPs) particles were confirmed by analysing the excitation of surface plasmon resonance (SPR) using UV-vis spectrophotometer at 433 nm. Further TEM analysis confirmed the range of particle size as 23 +/- 2 nm. The XRD spectrum showed the characteristic Bragg peaks of 111,200,220 and 311 facets of the face centered cubic silver nanoparticles and confirms that these nanoparticles are crystalline in nature. Gas chromatography-mass spectrometry (GCMS) of coir extract confirms the presence of hydrocarbon such as nonacosane and heptacosane which may possibly influence the reduction process and stabilization of silver nanoparticles. This is the first account of C. nucifera coir assisted synthesis of biogenic Ag nanoparticles; the nanoparticles are notably smaller and better faceted compared with those synthesized by A. squamosa extracts previously reported. Synthesized Ag nanoparticles were effective anti-larvicidal agent’s against Anopheles stephensi and C. quinquefasciatus. (C) 2012 Elsevier B.V. All rights

“Objectives: Metabolism inhibitor Abdominal aortic aneurysms (AAAs), being predominantly atherosclerotic in nature, have underlying inflammatory activity. As it is well established that ultrasmall superparamagnetic iron oxide (USPIO)

particles accumulate in the macrophages within atheromatous lesions, USPIO-enhanced magnetic resonance (MR) imaging can be potentially effective in the quantification of the associated inflammatory processes.

Methods: A total of 14 patients underwent USPIO-enhanced MR imaging using a 1.51-MR system. Quantitative T(2)* and T(2) relaxation time data were acquired before and 36 h after UPSIO infusion at identical AAA locations. The pre- and post-USPIO-infusion relaxation times (T(2)* and T(2)) were quantified and the correlation between pre- and post-USPIO infusion T(2)* and T(2) values was investigated.

Results: There was a significant ABT-737 ic50 difference between pre- and post-infusion T(2)* and T(2) values (both respective p-values = 0.005). A significant correlation between T(2)* and T(2) values post-USPIO infusion was observed (r = 0.90, p < 0.001), which indicates USPIO uptake by the aortic wall.

Conclusions: Aortic wall inflammation using USPIO-enhanced MR imaging is feasible. Use of quantitative T(2) and T(2)* pulse sequences provides a quantitative method for assessing USPIO uptake by the aortic wall. (C) 2010 European Society for Vascular Surgery.
