AIM:To evaluate the Z-line visualization by the PillCamTM SB2 using three different ingestion protocols. METHODS:Ninety consecutive patients undergoing small bowel capsule endoscopy(SBCE)between January and May 2008 were included in the study. They swallowed the capsule in the standing(Group A= 30),supine(Group B=30)and right supine positions (Group C=30).Baseline patient characteristics, difficulties in capsule ingestion,esophageal transit times(ETT)and Z-line visualization were noted. RESULTS:No significant differences were found between the groups with regard to baseline patient characteristics,ingestion difficulties and complete SB examinations(P>0.05).At least 1 frame of the Z-line was detected in 15.8%,46.7%and 90%of patients in groups A,B and C,respectively(P<0.001).The average number of Z-line images was 0.21±0.53,3.23 ±6.59 and 5.53±7.55 and the mean%of the Z-linedetected was 71.3,25.1 and 8.3,in groups A,B and C, respectively(both P<0.001).ETT times were longer in the supine group followed by the right supine and the standing groups(median of 237 s vs 64 s and 39 s, respectively;P<0.001). CONCLUSION:Z-line visualization in patients undergoing SBCE can be accurately achieved in most cases when the capsule is swallowed in the right supine position.

Arginine-glycine-aspartic acid （RGD） dendrimer-based nanopatterns on poly（L- lactic acid） were used as bioactive substrates to evaluate the impact of the RGD local surface density on the chondrogenic induction of adult human mesenchymal stem cells. During chondrogenic commitment, active extracellular matrix （ECM） remodeling takes place, playing an instructive role in the differentiation process. Although three-dimensional environments such as pellet or micromass cultures are commonly used for in vitro chondrogenic differentiation, these cultures are rather limited with respect to their ability to interrogate cells in celI-ECM interactions. In the present study, the nanopatterns of the tunable RGD surface density were obtained as a function of the initial dendrimer concentration. The local RGD surface density was quantified through probability contour plots for the minimum interparticle distance, constructed from the corresponding atomic force microscopy images, and correlated with the cell adhesion and differentiation response. The results revealed that the local RGD surface density at the nanoscale acts as a regulator of chondrogenic commitment, and that intermediate adhesiveness of cells to the substrates favors mesenchymal cell condensation and early chondrogenic differentiation.

The Gentio metagranitoid presents equigranular and porphyritic facies, modal composition ranging from tonalite to monzogranite with calculated T_(Zr)6 wt.%). Zircon analyses by LA-ICP-MS and SHRIMP yielded a concordia age of 2 119±10 Ma for the porphyritic facies and an upper intercept age of 2 111±15 Ma for the equigranular facies. The whole-rock Sm-Nd T_(DM) ages vary from 2.4 to 2.8 Ga with ε_(Nd)(2.1) values between -0.7 and-5.3, indicating crustal derivation from distinct and/or heterogeneous protoliths. Field observations indicate that the Gentio metagranitoid was formed through different pulses of magma. Individual batches were subject to little or even no fractionation process after its emplacement. Although the Gentio metagranitoid crosscuts metamafic and metaultramafic rocks akin to an oceanic arc setting, this pluton is likely originated by partial melting of a more evolved quartz-feldspathic crustal igneous rock in a post-collisional environment, after the accretion of the arcs from the Mineiro belt and rocks of the Mantiqueira Complex.

In this work, we prove the existence and uniqueness of the solution of the generalized Schrödinger equation in the periodic distributional space P’. Furthermore, we prove that the solution depends continuously respect to the initial data in P’. Introducing a family of weakly continuous operators, we prove that this family is a semigroup of operators in P’. Then, with this family of operators, we get a fine version of the existence and dependency continuous theorem obtained. Finally, we provide some consequences of this study.
