A detailed study has been carried out to investigate the effect of applied current density on the composition, crystallographic structure, grain size, and surface morphology of fe-Cu films. X-ray diffraction （XRD） results show that the films consist of a mixture of face-centered cubic （fcc） Cu and body centered cubic （bcc） ^-fe phases. The average crystalline size of both fe and Cu particles decreases as the applied current density becomes more negative. Compositional analysis of fe-Cu films indicates that the fe content within the films increases with decreasing current density towards more negative values. Scanning electron microscopy （SEM） and atomic force microscopy （AfM） have been used to investigate the surface morphology of fe-Cu films. It is observed that the surface morphology of the films changes from dendritic structure to a cauliflower structure as the applied current density becomes more negative. The surface roughness and grain size of the fe-Cu films decrease with decreasing applied current density towards more negative values.

Surface morphology and its relationship with microstructure in Ta/Nife/IrMn/Cofe/Ta multilayer system deposited by pulsed DC magnetron sputtering have been investigated in dependence of Ta buffer and Nife seed layer thicknesses using atomic force microscopy. The structural parameters such as grain size, dislocation density, texture and strain were calculated. for each surface, a self-affinity behavior with mean fractal dimensions in the range of 2.03-2.18 was found. Additionally, it was also observed that the surface of all samples has locally smooth textured surface structure in the short range. The texture aspect parameter and texture direction index have been obtained for isotropy/anisotropy surface texture. A significant relationship between the surface texture and the strength of the 〈111〉 texture in IrMn layer has been found. The analysis indicated that the surface roughness is strongly affected by the thicknesses of the Nife seed and Ta buffer layers.

AIM: The mechanism of tramadol-induced vasodilation was investigated using isolated rabbit thoracic aortic rings. METHODS: Aortic rings from 8 rabbits were placed in organ bath and precontracted with phenylephrine(10-5mol/L) before addition of tramadol. Relaxation responses by tramadol were evaluated in the presence and absence of endothelium, indomethacin （an inhibitor of cyclooxygenase）, NG-nitro-L-arginine methyl ester （L-NAME, a specific inhibitor of nitric oxide synthase）, glibenclamide （an inhibitor of ATP-sensitive potassium channels）, tetraethylammonium chloride （TEA, an inhibitor of calcium-sensitive potassium channels）, and naloxone （an antagonist of opioid receptors）. RESULTS: Tramadol(10-4mol/L and 3×10-4mol/L) caused significant vasodilation in endothelium-intact and endothelium-denuded aortic rings （Pficantly greater in endothelium-intact rings than in endothelium-denuded rings.

Objective: Appetite loss is seen in 90% to 95% of patients with acute appendicitis;however, the cause of this symptom remains unknown. This study is performed to determine whether changes in the blood levels of two anorexigenic hormones, leptin and NUCB2/nesfatin-1, can help to diagnose acute appendicitis in children and whether these two parameters can distinguish acute appendicitis from abdominal pain. Methods: Sixty children with comparable ages and body mass indices are divided into three groups of 20 children each: those with acute appendicitis, those with abdominal pain, and controls. The blood sample with acute appendicitis is taken preoperatively (T1), and subsequent samples are taken 24 hrs postoperatively (T2) and 3 days postoperatively (T3). The blood sample with abdominal pain subjects is also taken in the corresponding times with those with acute appendicitis while blood sample from controls is only taken in the T1 corresponding time. Leptin and NUCB2/nesfatin-1 levels are measured by enzyme-linked immunosorbent assay. Results: The serum leptin levels are significantly higher preoperatively than postoperatively in all three groups. The NUCB2/nesfatin-1 levels at T1 in acute appendicitis are significantly higher than those at T2 in all three groups, but are restored at T3 to levels similar to those of controls. Neutrophil percentage has a sensitivity of 100%, and specificity of 76.32%, NUCB2/nesfatin-1 level has a sensitivity of 47% and specificity of 95%, and the leptin level has a sensitivity of 64% and specificity of 51% in the diagnosis of acute appendicitis. Conclusions: High preoperative leptin and NUCB2/nesfatin-1 levels may be a causative factor for appetite suppression observed in patients with acute appendicitis. High preoperative and low postoperative serum leptin and NUCB2/nesfatin-1 concentrations may serve as new candidate biomarkers that help to distinguish acute appendicitis from abdominal pain in children in addition to high CRP concentr
