Their structures were elucidated on the basis of spectroscopic and physicochemical analyses. All the isolates were evaluated for in vitro inhibitory activity against DGAT1 and DGAT2. Among them, compounds 1-6 were found to exhibit selective inhibitory activity on DGAT1 with IC50 values ranging from 61.1 1.3 to 97.7 1.1 111\4 and compound 7 showed selective inhibition of DGAT2 with IC50 value 93.2 1.2.

Single poly-EEPROM with stacked MIM and n-well capacitor
Cui, Z.-Y.,Choi, M.-H.,Kim, Y.-S.,Lee, H.-G.,Kim, K.-W.,Kim, N.-S. IET 2009 Electronics letters Vol.45 No.3
<P>The new structure of electrically erasable programmable read-only memory (EEPROM), using a capacitor of stacked metal-insulator-metal (MIM) and <I>n</I>-well, is proposed. The oxide capacitance in the <I>n</I>-well region is effectively applied without sacrificing the cell area and the control gate coupling ratio. Therefore, for the same program-voltage rating, the proposed cell allows the EEPROM to have a higher speed handling capability even with a quite small cell size. Measured results show that the programming speed of the proposed cell is almost the same as that of the conventional MIM control gate cell. In an endurance test of 10 000 program/erase cycles, the shift of program threshold voltage is found to be 1.4 V without degradation of read currents.</P>

Cui, X.M.,Yang, Z.B.,Yang, W.R.,Jiang, S.Z.,Zhang, G.G.,Liu, L.,Wu, B.R.,Wang, Z.F. Asian Australasian Association of Animal Productio 2013 Animal Bioscience Vol.26 No.10
This experiment was conducted to study the variation laws and correlations of shearing force and feed characteristics including morphological characteristic, chemical composition and in situ degradability of wheat straw. Feasibility of evaluating the nutritional value of wheat straws with shearing force values was analyzed in this study. Six hundred wheat straw plants (Jimai 22) were randomly selected and placed in a cool and ventilated place. Samples were collected in the 1st, 15th, 30th, 45th, 60th d after harvest to measure shearing force, morphological characteristic, nutritional composition. Rumen degradation of dry matter (DM), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of wheat straws were determined by the nylon bags method. The results demonstrated that linear and quadratic effects of storage time on all the tested morphological characteristics were significantly correlative (p<0.01). As storage time goes on, all the tested nutrients and their rumen degradations of wheat straw was linearly (p<0.01) and quadratic (p<0.01) correlative except ADF content and rumen degradation of ADF. Significant correlations were determined in linear effect of shearing force on morphological characteristics (p<0.01), and linear density and diameter were a more sensitive predictor than stem thickness for shearing force. There were strong correlations between storage time and all the measured physical characteristics (shearing force, morphological characteristics and shearing force standardized by morphological characteristics) (p<0.01). Nutrition compositions were linearly correlative with shearing force and standardized shearing force (p<0.01). The linear correlation between rumen degradation of DM and NDF and shearing force and standardized shearing force were evident (p<0.01). In conclusion, shearing force, nutrition compositions and their rumen degradation of wheat straw were still dynamic with storage time after harvest. Correlation could be found between shearing force and nutritional characteristics of wheat straw. Nutrient content, morphological index and rumen degradation of DM and NDF could be predicted by changes in shearing force. Shearing force should be applied according to a standardized storage time when it is used to forecast the feed value of wheat straws.

Edge cracks in cold rolling always influence to the quality of productions, while the “V” shaped cracks were propagated by passing the roll gap. We set up the sizes and shapes of initial cracks in simulation according to the references form real productions. Different to in hot rolling, the cracks in cold rolling couldn’t be reduced from propagation automatically after generate, even if these could be reduced by changing the process parameters. In this paper, we described the affections of process parameters on the propagation of edge cracks, such as reduction ration and tension. We predicted that the dependence of the cracks propagations of changing of process conditions and expected to gain the smaller edge cracks. By raising the reduction ratio, the cracks were propagated increasingly in both transverse and rolling directions. And as tension raise, the cracks became propagated in both directions in which transverse direction was less effectively.

<P>Herein we systematically study a range of dopants (Cr, Fe, Ni, Cu, and an MnCo alloy) in ZnO and TiO<SUB>2</SUB> using several X-ray spectroscopic techniques. We identify the dopant’s local environment and interaction with the host lattice by employing crystal field multiplet calculations and hence clarify their potential applicability for spintronic technologies. Our density functional theory (DFT) calculations predict a decreasing probability of direct cation (Zn/Ti) substitution by dopant atoms as atomic number increases, as well as a much greater likelihood of metallic clustering in TiO<SUB>2</SUB>. Our spectroscopic measurements confirm that in all cases, except Mn, metallic clusters of dopant atoms form in the TiO<SUB>2</SUB> crystal lattice, thus making it unfit for spintronic capabilities. On the other hand, in ZnO, the dopants substitute directly into zinc sites, which is promising for spintronic technologies.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2014/jpccck.2014.118.issue-48/jp509761c/production/images/medium/jp-2014-09761c_0011.gif'></P>

Ursolic acid is reported to have beneficial effects on the regulation of cardiovascular homeostasis. However, the effects of ursolic acid on cardiac hormone secretion are yet to be defined. The present study was designed to test the effects of ursolic acid on the secretory and contractile functions of the atria. Experiments were conducted in isolated perfused beating rabbit atria. We measured the changes in atrial dynamics, pulse pressure, stroke volume, cAMP efflux, as well as the secretion of atrial natriuretic peptide (ANP). Ursolic acid increased ANP secretion and mechanical dynamics in a concentration-dependent manner. The inhibition of L-type Ca<SUP>2+</SUP> channels with nifedipine attenuated the ursolic acid-induced increase in ANP secretion but not mechanical dynamics. The inhibition of K<SUP>+</SUP><SUB>ATP</SUB> channels with glibenclamide attenuated the ursolic acid-induced increase in ANP secretion-but not atrial dynamics-in a concentration-dependent manner. The selective Na<SUP>+</SUP>-K<SUP>+</SUP>-ATPase inhibitor ouabain blocked the ursolic acid-induced increase in atrial dynamics but not ANP secretion. These findings show that ursolic acid increases ANP secretion via its activation of K<SUP>+</SUP><SUB>ATP</SUB> channels and subsequent inhibition of Ca<SUP>2+</SUP> entry through L-type Ca<SUP>2+</SUP> channels in rabbit atria. These data also suggest that ursolic acid increases atrial dynamics via its inhibition of Na<SUP>+</SUP>-K<SUP>+</SUP>-ATPase activity.
