| 1 | Method for converting in-situ gamma ray spectra of a portable Ge detector to an incident photon flux energy distribution based on Monte Carlo simulation显示文摘A matrix stripping method for the conversion of in-situ gamma ray spectrum, obtained with portable Ge detector, to photon flux energy distribution is proposed. The detector response is fully described by its stripping matrix and full absorption efficiency curve. A charge collection efficiency function is introduced in the simulation to take into account the existence of a transition zone of increasing charge collection after the inactive Ge layer. Good agreement is obtained between simulated and experimental full absorption efficiencies. The characteristic stripping matrix is determined by Monte Carlo simulation for different incident photon energies using the Geant4 toolkit system. The photon flux energy distribution is deduced by stripping the measured spectrum of the partial absorption and cosmic ray events and then applying the full absorption efficiency curve. The stripping method is applied to a measured in-situ spectrum. The value of the absorbed dose rate in air deduced from the corresponding flux energy distribution agrees well with the value measured directly in-situ. | Boubaker ASKRI Adel TRABELSI Brahim BACCARI | 2008 | Nuclear Science and Techniques2008，19，6： | 3 |
| 2 | Adiponectin affects the mechanical responses in strips from the mouse gastric fundus显示文摘AIM To investigate whether the adipocytes derived hormone adiponectin(ADPN) affects the mechanical responses in strips from the mouse gastric fundus. METHODS For functional experiments, gastric strips from the fundal region were cut in the direction of the longitudinal muscle layer and placed in organ baths containing KrebsHenseleit solution. Mechanical responses were recorded via force-displacement transducers, which were coupled to a polygraph for continuous recording of isometric tension. Electrical field stimulation(EFS) was applied via two platinum wire rings through which the preparation was threaded. The effects of ADPN were investigated on the neurally-induced contractile and relaxant responses elicited by EFS. The expression of ADPN receptors, Adipo-R1 and Adipo-R2, was also evaluated by touchdown-PCR analysis. RESULTS In the functional experiments, EFS(4-16 Hz) elicited tetrodotoxin(TTX)-sensitive contractile responses. Addition of ADPN to the bath medium caused a reduction in amplitude of the neurally-induced contractile responses(P < 0.05). The effects of ADPN were no longer observed in the presence of the nitric oxide(NO) synthesis inhibitor L-NG-nitro arginine(L-NNA)(P > 0.05). The direct smooth muscle response to methacholine was not influenced by ADPN(P > 0.05). In carbachol precontracted strips and in the presence of guanethidine, EFS induced relaxant responses. Addition of ADPN to the bath medium, other than causing a slight and progressive decay of the basal tension, increased the amplitude of the neurally-induced relaxant responses(P < 0.05). Touchdown-PCR analysis revealed the expression of both Adipo-R1 and Adipo-R2 in the gastric fundus.CONCLUSION The results indicate for the first time that ADPN is able to influence the mechanical responses in strips from the mouse gastric fundus. | Eglantina Idrizaj Rachele Garella Giovanni Castellini Hermine Mohr Natalia S Pellegata Fabio Francini Valdo Ricca Roberta Squecco Maria Caterina Baccari | 2018 | World Journal of Gastroenterology2018，24，35： | 2 |
