BACKGROUND Mandibular prognathism is often corrected by surgical orthodontics. Correction of the sagittal facial profile has received wide attention. However, vertical changes remained undefined and thus, were investigated. METHODS Subjects included 18 patients with mandibular prognathism who had surgical correction (S group, mean age: 20.1 +/- 3.2 years) and 18 patients with Class I malocclu...

BACKGROUND AND PURPOSE Gamma knife radiosurgery is an alternative for the treatment of medically refractory trigeminal neuralgia. Few reports of posttreatment MR imaging appearance of cranial nerve V exist. Our purpose was to define MR imaging characteristics in cranial nerve V after gamma knife radiosurgery. METHODS We retrospectively reviewed MR images of 15 patients who underwent gamma kni...

Introduction: The area at risk (AAR) of infarction is the hypoperfused myocardial bed during coronary occlusion. The edematous AAR can be delineated in-vivo by T2 MRI and can be used in conjunction with delayed contrast enhancement to calculate myocardial salvage. T1 MRI has been recently used to image the edema associated with acute myocardial infarction. Objectives: We hypothesized that, due ...

conclusions in the case of existence gaussian noise, the results confirm that denoising is not effective on the measurement of t2* value. in the case of image distortion by rician noise, a predictor model is proposed to estimate the original t2* value. the predictor model is used to estimate the t2* value of new patients. the predicted t2* values were in good agreement with the corresponding or...

OBJECTIVE Our primary objective was to evaluate the effect of peer counselling by mother support groups (MSG's) in improving the infant and young child feeding (IYCF) practices in the community. METHODS We conducted this repeated-measure before and after study in the Lalitpur district of Uttar Pradesh, India between 2006 and 2011. We assessed the IYCF practices before and after creating MSG's...

The aim of this study was to detect the major bacteria present in rumen microbiota. Here, we performed qPCR based absolute quantitation of selected rumen microbes in rumen fluid of river buffalo adapted to varying proportion of concentrate to roughage diets. Animals were adapted to roughage-to-concentrate ratio in the proportion of 100:00 (T1), 75:25 (T2), 50:50 (T3) and 25:75 (T4) respectively...

laboratory degradation studies were performed in water at ph 4.0, 7.0 and 9.2 using benthiocarb (saturn 50 ec) formulation at the rates of 1.0 (t1) and 2.0 (t2) î¼g/ml. water samples collected on 0 (2h),3,7,15,30,45,60 and 90 days after treatments were processed for residue analysis of benthiocarb by gc-npd capillary system. in 60 days, dissipation was 92.82-93.81 % at ph 4.0, 89.12-90.63 % at ...

BACKGROUND AND PURPOSE To our knowledge, no method satisfactory for clinical use has been developed to visualize white matter fiber tracts with diffusion-weighted MR imaging. The purpose of this study was to determine whether superposition of a spin-echo T2-weighted image and a color-coded image derived from three orthogonal diffusion-weighted images could show fiber tract architecture of the b...
