The oil in mackerel muscle was extracted using an environment friendly solvent, supercritical carbon dioxide (SC-$CO_2$) at a semibatch flow extraction process and an n-hexane. The SC-$CO_2$ was maintained at a temperature of $45^{\circ}C$ under pressures ranging from 15 to 25 MPa. The flow rate of $CO_2$ (27 g/min) was constant during the entire 2 h extraction period. The fatty acid composition of the oil was analyzed using gas chromatography (GC). Significant concentrations of eicosapentaenoic acid (EPA) acid and docosahexaenoic acid (DHA) acid were present in the SC-$CO_2$ extracted oil. The oil extracted using SC-$CO_2$ exhibited increased stability compared with n-haxane extracted oil. Particles of mackerel oil together with the biodegradable polymer, polyethylene glycol (PEG) were formed using a gas saturated solution process (PGSS) with SC-$CO_2$ in a thermostatted stirred vessel. Different temperatures ($45-55^{\circ}C$), pressures (15-25 MPa) and a nozzle size $400{\mu}m$ were used for PGSS with a 1 h reaction time. The stability of mackerel oil in the particles did not changed significantly.

Field experiment was conducted during 1993-94 season to determine the pattern of nutrient uptake and productivity of maize/sweet potato intercropping system. Four levels of nitrogen (0, 50, 100 and 150kg N ${ha}_{-1}$) and four levels of potassium (0, 40, 80 and 120kg $K_2$O ${ha}_{-1}$) formed treatment variables. Plants were sampled periodically to determine dry matter and tissue concentrations of N and K in the individual plant components of intercropped maize and sweet potato. Nitrogen and potassium fertilizer did not interact significantly to nutrient uptake by any plant parts of intercropped maize and sweet potato. But application of N fertilizer independently enhanced N uptake in all the plant parts of maize and sweet potato. The uptake of N in leaf, leaf sheath, stem, husk, and cob of maize increased upto 90 days after planting (DAP) but grain continued to accumulate N till its maturity. Sweet potato exhibited a wide variation in N uptake pattern. Sweet potato leaf shared the maximum uptake of N at 50 DAP which rapidly increased at 70 DAP and then declined. Declination of N uptake by petiole and stem were observed after 120 DAP whereas N uptake by tuber increased slowly upto 90 DAP and then rapidly till harvest. Rate of applied K had very little effect on the uptake patterns in different components of intercropped maize. Pattern of K uptake by leaf, petiole and stem of sweet potato showed almost similar trend to N uptake. But uptake of K by tuber increased almost linearly with the K application. Pattern of N and K uptake by grain and tuber paralleled the grain yield of maize and sweet potato respectively. Intercropped productivity of maize and sweet potato found to be better by the application of 100kg N and 120 kg $K_2$O ${ha}_{-1}$

The pharmacological effects of an Ayurvedic diuretic drug 'Treenoponchomul' (TPM) was investigated in animal model. The pharmacological actions of the test drug along with that of the components thereof, on the Central Nervous System (CNS) were studied. The drug under study TPM showed little effect on the CNS, the same can not be said about the components. The most prominent CNS depressant effect was observed with Saccharum officinarum Linn. (EE) in that it lowered the spontaneous motor activity as well the exploratory -behavior of the animals. An exploration retarding effect of moderate degree, was evident with Imperata cylindrica Beauv. (UU), and Phragmites maxima Blatter & McCann (NN). Although the test drug did not alter the normal locomotor and/ or exploratory behavior of the treated animals, it did significantly (p<0.01) lower the locomotion of the amphetamine induced hyperactive animals. TPM along with its components (especially Desmostachya bipinnata Stapf. Root, KU), significantly reduced the gastro-intestinal motility of the treated animals (p<0.01). The test drug and its components lowered the body weight of the treated animals, on being administered chronically (30 days), with EE being the only exception.
Adsorption of Phenol on Mesoporous Carbon CMK-3: Effect of Textural Properties
Haque, Enamul,Khan, Nazmul Abedin,Talapaneni, Siddulu Naidu,Vinu, Ajayan,JeGal, Jong-Geon,Jhung, Sung-Hwa Korean Chemical Society 2010 Bulletin of the Korean Chemical Society Vol.31 No.6
Mesoporous carbon CMK-3s with different textural properties have been used for the adsorption of phenol to understand the necessary physicochemical properties of carbon for the efficient removal of phenol from contaminated water. The kinetic constants (both pseudo-second order and pseudo-first-order kinetics) increase with increasing pore size of carbons. The maximum adsorption capacities correlate well with micropore volume compared with surface area or total pore volume even though large pore (meso or macropore) may contribute partly to the adsorption. The pore occupancies also explain the importance of micropore for the phenol adsorption. For efficient removal of phenol, carbon adsorbents should have large micropore volume and wide pore size for high uptake and rapid adsorption, respectively.

The yeast-26S rRNA libraries were constructed from two different fermented soybean foods, doenjang and kanjang. A total of 42 clones, containing the partial 26S rRNA sequences, 0.6 kb in length, were sequenced and subjected to an online similarity search. All doenjang yeast (DY) clones only appeared in the Saccharomycotina class. The 21 clones from the doenjang library were classified into five groups: Debaryomyces hansenii (DY I, 76.0 %), Zygosaccharomyces pseudorouxii (DY II, 9.6 %), Candida versatilis (DY III, 4.8 %), Candida etchellsii (DY IV, 4.8 %), and Debaryomyces castellii (DY V, 4.8 %). The 21 kanjang yeast (KY) clones were affiliated with the Saccharomycotina (52.4 %), Urediniomycetes (19.0 %), Ustilaginomycetes (23.8 %), and Hymenomycetes (4.8 %) classes and divided into six groups: D. hansenii (KY I, 38.0 %), Sterigmatomyces halophilus (KY II, 19.0 %), Malassezia restricta (KY III, 23.8 %), Cryptococcus magnus (KY V, 4.8 %), and Pichia triangularis (KY VI, 9.6 %). Yeast belonging to the Saccharomycotina class was predominant (76.2 %) in fermented soybean foods, doenjang and kanjang. These findings are of fundamental value for understanding the complexity of two different fermented soybean foods.

<P>Abnormal tau aggregates are presumed to be neurotoxic and are an important therapeutic target for multiple neurodegenerative disorders including Alzheimer’s disease. Growing evidence has shown that tau intermolecular disulfide cross-linking is critical in generating tau oligomers that serve as a building block for higher-order aggregates. Here we report that a small molecule inhibitor prevents tau aggregation by blocking the generation of disulfide cross-linked tau oligomers. Among the compounds tested, a rosamine derivative bearing mild thiol reactivity selectively labeled tau and effectively inhibited oligomerization and fibrillization processes <I>in vitro</I>. Our data suggest that controlling tau oxidation status could be a new therapeutic strategy for prevention of abnormal tau aggregation.</P>

<P>Several porous materials such as metal–organic frameworks (MOFs) and aluminophosphates have been synthesized with microwave and conventional electric heating in various temperatures and times to investigate the quantitative acceleration in the synthesis of porous materials by microwaves. From the analysis of the acceleration under microwave heating with the Eyring equation, it can be understood that, irrespective of the type of porous materials, the acceleration by microwaves is mainly due to decreased activation free energy (Δ<I>G</I><SUP>⧧</SUP>) even though the activation energy (<I>E</I><SUB>a</SUB>) and activation enthalpy (Δ<I>H</I><SUP>⧧</SUP>) are increased. The decreased activation free energy is mainly due to the high activation entropy (Δ<I>S</I><SUP>⧧</SUP>) of microwave synthesis compared with the entropy of conventional electric synthesis. Accelerated synthesis with microwaves may be explained with changes of relative energies of intermediates for high activation entropy.</P><P>The accelerated synthesis of porous materials under microwave is mainly due to the decreased activation free energy even though the enthalpy and activation energy are increased.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/cgdefu/2011/cgdefu.2011.11.issue-10/cg200594e/production/images/medium/cg-2011-00594e_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/cg200594e'>ACS Electronic Supporting Info</A></P>

The diversity of bacterial endophytes associated with Chinese cabbage (CC) leaves from two cultivation areas in Korea, namely, Seosang-gun (SS) and Haenam-gun (HN), and from a laboratory transgenic plant (TP) was investigated. A total of 5.76 log CFU/g isolates were identified from the interior leaves of the three cultivars of CC, which were grouped into 5.08, 5.36, and 5.34 log CFU/g from SS, HN, and TP samples, respectively. Phylogenetic analysis based on the 16S rRNA sequences indicated that the isolates belonged to four major phylogenetic groups: high-G + C Gram-positive bacteria (HGCGPB), low-G + C Gram-positive bacteria (LGCGPB), Proteobacteria, and Bacteroidetes. The most predominant group of species in the leaves of the SS, HN and TP CC cultivars were LGCGPB (50%), LGCGPB (65.2%), and HGCGPB (43%), respectively. A total of 23 bacterial genera were identified from the three cultivars of Chinese cabbage. Most extracellular hydrolytic enzyme-producing colonies among the isolates belong to the genus Bacillus those were predominant in the HN cultivars. In addition, some isolates especially Bacillus sp. (TPL08), Bacillus subtilis (SSL16, HNL10) exhibited potential activity as biocontrol agents against food-borne pathogenic bacteria and phytopathogenic fungi tested in this study. This study first revealed the endophytic bacterial communities in leaves of Chinese cabbage (main ingredients of kimchi) grown in Korea.
