Hyperlipidemic control (Group 2) was compared with control (Group 1). Hyperlipidemic + A. indicus treated (Group 3) and hyperlipidemic + gemfibrozil (Group 4) was compared with hyperlipidemic control...Bottom Line: In this model, feeding with root extract (500 mg kg(-1) b.w.) lowered plasma lipids and reactivated post-heparin lipolytic activity in hyperlipidemic rats.Furthermore, the root extract (50-500 μM) inhibited the generation of superoxide anions and hydroxyl... | Kumar V, Khan MM, Khanna AK, Singh R, Singh S, et al. - Evid Based Complement Alternat Med (2008) |

 | Walking on inclines: how do desert ants monitor slope and step length. | Figure 6: Schematic drawing of the setup used in experiment 1 (side view). While foraging from the nest to the feeder the ants passed a narrowed section of the channel, within which they were recorded from above (x-y plane, see arrow). The inclination of this section...Bottom Line: After removing the effect of speed, slope had only marginal influence on kinematic parameters.From the obtained data we infer that the previously proposed monitoring of angles of the thorax-coxa joint is not involved in inclinometry.Due to the tiny variations... | Seidl T, Wehner R - Front.

The food intake in the baseline group represents the value for normal rats without TMJ inflammation. The effect of retigabine or retigabine and XE991 was tested 24 hours after CFA injection....Bottom Line: Food intake is known to be negatively associated with TMJ inflammation.Food intake was increased significantly by the administration of retigabine (2.5 and 7.5 mg/kg), and this effect was reversed by XE991 (3 mg/kg).Furthermore, intracerebralventricular injection... | Xu W, Wu Y, Bi Y, Tan L, Gan Y, Wang K - Mol Pain (2010) |

![Assay of PNGase activity in an E. coli cell-free extract. The E. coli strain used was BL21(DE3)pLysS. Shown is a paper chromatogram of the reaction product formed after 10 min of incubation of the E. coli extract with labeled substrate. (lane 1) E. coli extract with pET-28b-PNG1; (lane 2) E. coli extract with pET-28b (control vector); and (lane 3) E. coli extract without vector. The extra minor band indicated with an asterisk was confirmed to be [14C]Leu-Asp by analysis by paper electrophoresis, as described earlier (Kitajima, et al. 1995), and may be derived from a contaminating protease activity in the E. coli extract. In fact, this degradation product represents a fraction of the product of PNGase activity because the second amino acid in the substrate was converted into Asp instead of remaining as Asn. P, de-N-glycosylated product ([14C]-Leu-Asp-Asn-Ser-Arg); and S, substrate ([14C]-Leu-Asn(Glc NAc5Man3Gal3)-Asn-Ser-Arg).
