<P>Polygonum cuspidatum is a potent anti-oxidant herb that is well known for its various bioactivities. The current study investigates which compound group is most effective, to establish the key compound groups for quality assessment, especially in terms of neuroprotective effects. The roots of P. cuspidatum were extracted with 85% methanol and fractionated with hexane, ethyl acetate, n-butanol and water. Each fraction was applied to an in vitro radical scavenging assay, a lipid peroxidation assay in brain homogenates and an in vivo assay using a transient focal cerebra ischemia model induced by a middle cerebral artery occlusion in a Sprague-Dawley rat. The ethyl acetate fraction was the most effective fraction in both in vitro and in vivo assays, having the highest stilbene and anthraquinone contents. These results suggest that stilbenes and anthraquinones may be key compound groups for the quality assessment of the anti-oxidative and neuroprotective effects of P. cuspidatum.</P>

<P>For long-term storage of renewable energy, the electrochemical carbon dioxide reduction reaction (CO<SUB>2</SUB>RR) offers a promising option for converting electricity to permanent forms of chemical energy. In this work, we present highly selective ethylene production dependent upon the catalyst morphology using copper oxide nanoparticles. The branched CuO nanoparticles were synthesized and then deposited on conductive carbon materials. After activation, the major copper species changed to Cu<SUP>+</SUP>, and the resulting electrocatalyst exhibited a high Faradaic efficiency (FE) of ethylene reaching over 70% and a hydrogen FE of 30% without any byproducts in a neutral aqueous solution. The catalyst also showed high durability (up to 12 h) with the ethylene FE over 65%. Compared to cubic morphology, the initial branched copper oxide structure formed highly active domains with interfaces and junctions in-between during activation, which caused large surface area with high local pH leading to high selectivity and activity for ethylene production.</P> [FIG OMISSION]</BR>

<P><I>Abies koreana</I> Wilson (<I>A. koreana</I>) is a shrub or broadly pyramidal evergreen tree endemic in the mountainous regions of South Korea. We obtained the essential oil (EO) from alpine needle leaves of <I>A. koreana</I> by the supercritical fluid extraction (SFE) method. EO was analyzed by gas chromatography–mass spectrometry (GC–MS), and 68 compounds were identified constituting 95.66% of the oil. The major components were elemol (11.17%), terpinen-4-ol (9.77%), sabinene (8.86%), 10(15)-cadien-4-ol (7.16%), α-terpineol (6.13%), α-pinene (6.07%) and γ-terpinene (4.71%). To investigate the memory-enhancing effects, we conducted a passive avoidance test using a scopolamine (1 mg/kg, ip)-induced amnesia mouse model. A peritoneal injection of EO from <I>A. koreana</I> (100 mg/kg) showed a memory enhancing effect of 72.7% compared with the control. These results suggest that EO of <I>A. koreana</I> may be a useful therapeutic agent against such amnesia-inducing diseases as Alzheimer and vascular dementia.</P>

<P>The detection of formaldehyde at a very low concentration is a significant research topic, due to its detrimental impact on human health. In the present study, we fabricated a hierarchical structure by the rational assembly of single-crystalline Co<SUB>3</SUB>O<SUB>4</SUB> nanoparticles. A hollow morphology using sacrificial ZnO spheres could form a three-dimensional conducting network in a solid state. The resulting structure was selectively active for formaldehyde sensing, and the detection limit was 50 ppb, which was nearly close to the record-high value among the other semiconducting materials. Such superior properties were attributed to the regular, hierarchically assembled structures with a small crystalline domain size, a thin hollow morphology with a large surface area, and a three-dimensional conductive network with a narrow diameter. We believe that this hierarchical assembly can show great potential as a platform for improving human health through the monitoring of indoor environments.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2014/jpccck.2014.118.issue-45/jp505791v/production/images/medium/jp-2014-05791v_0009.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp505791v'>ACS Electronic Supporting Info</A></P>
Efficient Procedural Modeling of Trees Based on Interactive Growth Volume Control
( Jinmo Kim ) 한국인터넷정보학회 2013 KSII Transactions on Internet and Information Syst Vol.7 No.9
The present study proposes efficient procedural modeling methods for enabling the growth and creation of various trees with minimal user control. Growth volume algorithms are utilized in order to easily and effectively calculate many parameters that determine tree growth, including branch propagation. Procedural methods are designed so that users` interactive control structures can be applied to these algorithms to create unique tree models efficiently. First, through a two-line-based interactive growth volume control method, the growth information that determines the overall shape of the tree is intuitively adjusted. Thereafter, independent branch control methods designed to control individual branches are added to the growth deformation in order to enable the growth of unique trees. Whether the growth processes of desired trees can be easily and intuitively controlled by the proposed method is verified through experiments. Methods that can apply the proposed methods are also verified.
