The A-not-B (AB) task has been hypothesized to measure executive/frontal lobe function; however, the developmental and measurement characteristics of this task have not been investigated. Performances on AB and comparison tasks adapted from developmental and neuroscience literature was examined in 117 preschool children (ages 23-66 months). Age significantly predicted performance on AB, Delayed...
BACKGROUND Few specific reports have addressed propranolol as a treatment for parotid hemangioma, and its mechanism remains unclear. METHODS Eighty-seven patients were recruited in this prospective study. Ten patients underwent detailed color Doppler examination. The depths, vessel densities, and resistant indices of 10 lesions were recorded and analyzed before treatment and at 1 and 3 months...
OBJECTIVES To examine the relationship between platelets (PLT) and platelets indices such as mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) as noninvasive biomarkers with testicular artery blood flow and fertility. METHODS Fifty-seven healthy and fertile men with normal semen values and 52 patients with abnormal semen values were included in the study. T...
BACKGROUND Abnormalities in left ventricular (LV) relaxation and/or increased filling pressures are indicators of LV diastolic dysfunction in patients with hypertension (HTN). The purpose of this study was to assess clinical use of pulsed wave Doppler, Doppler tissue imaging (DTI), and color M-mode (CMM) indices for determination of diastolic function in patients with HTN. METHODS In all, 278...
Waste oil is an inexpensive source for biodiesel production, but the high amount of impurities present (free fatty acids, oxidation products) impedes its practical application. The aim of this work is to assess the purification efficiency of the adsorption process with eggshell and its active carbon. Carbonization of eggshell was done at 200 ºC for 4 hours. For activation of the resultant carbo...
