OBJECTIVE This study compared the adequacy of dental cone beam computed tomography (CBCT) and micro computed tomography (micro-CT) in evaluating the structural parameters of trabecular bones. METHODS The cellular synthetic bones in 4 density groups (Groups 1-4: 0.12, 0.16, 0.20, and 0.32 g/cm3) were used in this study. Each group comprised 8 experimental specimens that were approximately 1 cm...
OBJECTIVE The objective of our study was to evaluate whether gray-scale and color Doppler ultrasound can reveal intestinal inflammation in infants with cow's milk allergy (CMA). SUBJECTS AND METHODS This study evaluated the clinical findings and grayscale and color Doppler sonograms of 34 infants. Seventeen 0- to 6-month-old infants with suspected CMA and 17 nonsymptomatic age-matched infants...
Dielectrophoresis is an efficient technique often used to handle or trap micro-/nano-particles within microfluidic devices. For that purpose, arrays of insulating materials disposed between polarization electrodes are classically used to generate the necessary dielectrophoresis forces. In this paper, a novel method is proposed where metallic micro dots are arrayed to generate strong field inhom...
OBJECTIVE Extracellular retention of PDGF-B has been proposed to play an important role in PDGF-B signalling. We used the PDGF-B retention motif knockout mouse (RetKO) to study the effects of retention motif deletion on development of micro- and macrovascular structure and function. METHODS Passive and active properties of conduit vessels were studied using myograph techniques and histologica...
UNLABELLED Statement of the Problem : Ameloblastoma is the most common odontogenic tumor which is slow-growing, locally invasive and exhibit specific biologic behavior and high recurrence rate. Likewise, odontogenic keratocyst is a developmental odontogenic cyst that has a high recurrence rate and aggressive behavior. There are limited studies considering the relationship between the angiogenes...
We experimentally investigate the primary superharmonic of order two and subharmonic of order one-half resonances of an electrostatic MEMS actuator under direct excitation. We identify the parameters of a one degree of freedom (1-DOF) generalized Duffing oscillator model representing it. The experiments were conducted in soft vacuum to reduce squeeze-film damping, and the actuator response was ...
