In this study, an efficient and facile technique for preparing graphene oxide in suspension and powder forms was presented based on a modification on Hummers' method followed by an additional ultrasonic process. The method involved the provision of graphene oxide from graphite by reaction of potassium permanganate and sulfuric acid with stabilizing the medium complex. Furthermore, this study ev...

callus and suspension cultures of lavandula angustifolia mill. (lamiaceae) were established and the effect of different culture media on growth rate was investigated. terpenoids added to suspension culture to investigate their biotrans-formation. all samples were analyzed by gas chromatography (gc) and gc-mass spectroscopy (ms). octan-1-ol, citronellol, linalool, borneol and geraniol were biotr...

Phospholipase C-gamma1, a tyrosine kinase substrate, hydrolyses phosphatidylinositol 4,5-bisphosphate to produce inositol 1,4,5-trisphosphate and diacylglycerol, which act as second messenger moleculesto mobilize intracellular calcium and activate protein kinase C, respectively. We have investigated the role of phospholipase C-gamma1 in anoikis, or cell death, induced by the loss of extracellul...

The purpose of this study was to summarize the clinical application and results of the double-loop locking cross-stitch suture and suspension fixation method for medial collateral ligament origin reconstruction. Thirty-six patients (21 males, 15 females) with an average age of 40 years (range = 17-58 years), who underwent treatment for acute fracture of the medial collateral ligament at our hos...

Introduction: Cerium oxide nanoparticles (CONPs) are used as radiation protection agent in the in-vivo and in-vitro studies. The distribution stability of nano-suspension is one of the important factors during the studies. The aim of this study is optimization of condition for CONPs dispersion with sodium dodecyl sulfate (SDS-anionic surfactant) and tween 20 (nonionic surfactan...

This study evaluated the bacteria removal efficiency, re-suspension and survivability within two structural Best Management Practices (BMPs) called Vortechs installed at two different sites in Providence, Rhode Island. Twelve rain storms were sampled during years 2004 and 2005. Five pathogenic indicator bacteria, E. coli, enterococci, fecal streptococci, total coliform, fecal coliform, were ana...

Synchronized suspension cultures are powerful tools in plant cell-cycle studies. However, few Arabidopsis cell cultures are available, and synchrony extending over several sequential phases of the cell cycle has not been reported. Here we describe the first useful synchrony in Arabidopsis, achieved by selecting the rapidly dividing Arabidopsis cell suspensions MM1 and MM2d. Synchrony may be ach...

introduction: transtibial amputation is the most common amputation in lower limbs. volume loss of residual limb occurs during daily use of prostheses, which results in pistoning between residual limb and prosthetic socket. the goal of this study was to design and fabricate a pneumatic suspension system in transtibial supracondylar prostheses and to evaluate its effect on residual limb pistoning...
