BACKGROUND We evaluated the effectiveness of narrow band imaging (NBI) in patients with oral squamous cell carcinoma (OSCC) after treatment. METHODS In all, 101 consecutive OSCC patients underwent NBI examination for posttreatment follow-up. Four patients had local recurrence. Twenty-six second primary malignancies were found in 18 patients; 6 patients (33%) had more than 1 lesion. Seventeen ...

monthly and seasonal concentrations of milk protein and urea and their relationships were investigated in 614 milk samples from 61 industrial holstein dairy herds in urmia, iran. milk samples were prepared monthly interval up to 12 months. the amount of 10 ml milk was prepared from each dairy herd when they were delivering to the milk factory. milk protein and urea concentration was evaluated b...

the effects of different levels of nitrogen (100, 200, 300 and 400 mg/l) and potassium (125, 250 and 375 mg/l) on yield and leaf n and k concentrations of tomato were investigated in perlit culture using a factorial randomized design with three replications. the highest fruit yield was obtained with 200 mg/l n. higher levels of nitrogen decreased tomato yield. with increasing nitrogen concentra...
