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.

Myocardial geometric remodeling is a response to increased stress which includes increased afterload situations during clinical conditions. In this review, we have focused on early and late geometric features in aortic stenosis, importance of recognition of these findings and consequences due to progression of valve disease. We have also pointed out the similarities in early focal and global myocardial geometric remodeling in acute and chronic conditions as hypertension and acute stress cardiomypathy which are associated with myocardial functional and geometric response to acute or chronic stress exposure and relevant increased afterload. In aortic stenosis, target organ involvement in disease progression has been evaluated and discussed in the report. In addition to quantitative evaluation of valve disease, importance of myocardial involvement and global assessment of patients with aortic stenosis also have been mentioned in the report. Finally, we have discussed the importance of global myocardial geometric changes and timing for surgery before development of heart failure in this specific group of patients.

Gastrointestinal stromal tumor (GIST) represents the most common mesenchymal malignancy of the gastrointestinal (GI) tract. In neurofibromatosis (NF), the increased incidence of tumor needs to be considered even in non-symptomatic individuals. Patients with neurofibromatosis NF type 1 have an increased risk of developing GI tumors including rare types such as GIST. We report a case of GIST in a 53-year-old male patient with neurofibromatosis. The patient was diagnosed with NF four years ago and his medical history revealed that he was hospitalized 5 times with a provisional diagnosis of massive lower gastrointestinal bleeding. GIST was diagnosed at explorative laparotomy and the tumor was 21 cm × 13 cm × 7 cm in size. Immunohistochemical examination showed that vimentin, actin and CD117 were positive. Computerized tomography showed peritoneal implants three months later. Imatinib mesylate (600 mg/d) was initiated. However, control computerized tomography revealed liver and omental metastasis. The dosage was elevated to 800 mg/d. Despite high dosage, the progression of the metastatic lesions continued in the liver and omentum. The patient started oral sunitinib malate (Sutent? Pfizer Inc, New York, NY, USA) 50 mg per day for 4 consecutive weeks, followed by 2 wk off per treatment cycle. The metastatic lesions in the liver and omentum were decreased in size after four courses, suggesting that sunitinib is also an effective treatment modality for metastatic GIST in NF patients.

Ventricular fibrillation seen just after declamping of the aorta is an undesirable condition causing myocardial injury. To return to normal rhythm, often internal shocks are applied. But defibrillation itself can also contribute to myocardial injury. So prevention of fibrillation is more important than treatment. 236 patients undergoing coronary artery by-pass surgery were included in this retrospective clinical study. 144 of those patients were operated using modified St. Thomas’ Hospital cardioplegic solution, for stopping the heart. In the other 92 patients, plegisol cardioplegic solution was used. We compared the two groups for the development of ventricular fibrilation after declamping of the aorta. In the modified St. Thomas’ Hospital group, ventricular fibrillation after declamping of the aorta was seen less frequently, this being statistically significant (22.2% vs. 52.2%, p = 0.026). This study shows that the modified ***’ Hospital cardioplegic solution is preferred for avoiding ventricular fibrillation occuring just after declamping of the aorta.

Background: Endovenous laser ablation is a relatively newer alternative to treat great saphenous vein insufficiency. We evaluated the efficiency and safety of treatment endovenous laser procedures on the different saphenous vein diameters with different energy levels. Methods: Data regarding endovenous laser ablation of symptomatic chronic great saphenous venous insufficiency in 209 patients were prospectively recorded. Patients were grouped into two main groups based on their diameters as 5 to 7 millimeters (Group A) or more than 7 millimeters (Group B). Patients in each group was randomized into two groups as >90 J/cm (A1 and B1) or 80-90 J/cm (A2 and B2). Postoperative outcome and complications were recorded during follow-ups at 1st week;1st, 3rd and 6th months to examine the venous reflux and recanalization. Results: Perioperative complaints as pain, cramps and ankle swelling were more commonly observed in A1 group. Fatigue was more common in A2 and B2 groups. No major complications as deep vein thrombosis or skin burns were observed. Conclusions: Endovenous laser ablation is a safe and effective procedure with a high satisfaction rate shortening hospitalization durations and early ambulant activity. Pain, ankle swelling and fatigue are the most common minor complaints in the early postoperative period.
