INTRODUCTION Before any new device can replace another for use in clinical practice, it is imperative that its reproducibility, diagnostic accuracy, and ability to detect changes over time are tested. OBJECTIVE To evaluate retinal nerve fiber layer (RNFL) measurements between two optical coherence tomography (OCT) systems: the Stratus OCT, a time domain system, and the Cirrus HD-OCT, a spectr...

We thank Siamak Sabour and Fariba Ghassemi for their interest in the IOHT. In our article, we reported that the newly developed IOHT showed strong concordance with the CROM, which is considered a gold standard for head posture measurement, and has relatively a good test–retest reliability, thereby proving its validity and reliability as a head posture– measuring device. First of all, in their l...

Aerobic power (VO2max) is an important indicator of the health and physical fitness. Executive problems in direct VO2max measurement has led to developing sub-maximal aerobic power prediction equations. The purpose of present study was to develop native aerobic power prediction equation based on 6-Minute Walk Test (6MWT) and body composition indices in children. In 192 healthy children (8 to 12...

An agar well diffusion bioassay method for determination of clarithromycin in human plasma, using Micrococcus Luteus ATCC 9341 as the assay organism, was compared with a selective high-performance liquid chromatographic (HPLC) method with UV detection. Spiked plasma was used to prepare standard and control samples for both methods. The results of the bioassay analyses with spiked plasma samples...

Background Three-dimensional (3D) ultrasonography is nonionizing and has been demonstrated to be a reliable tool for scoliosis assessment, including coronal sagittal curvatures. It shows great potential axial vertebral rotation (AVR) evaluation, yet its validity reliability need further demonstrated. Materials Methods Twenty patients with adolescent idiopathic (AIS) (coronal Cobb: 26.6 ± 9.1°) ...

PURPOSE To compare the reproducibilities of manual and semiautomatic segmentation method for the measurement of normalized cerebral blood volume (nCBV) using dynamic susceptibility contrast-enhanced (DSC) perfusion MR imaging in glioblastomas. MATERIALS AND METHODS Twenty-two patients (11 male, 11 female; 27 tumors) with histologically confirmed glioblastoma (WHO grade IV) were examined with ...

INTRODUCTION Total 25-hydroxyvitamin D [25(OH)D] is the most reliable indicator of vitamin D status. In this study, we compared two automated immunoassay methods, the Abbott Architect 25-OH Vitamin D assay and the Roche Cobas Vitamin D total assay, with the liquid chromatography-tandem mass spectrometry (LC-MS/MS). MATERIALS AND METHODS One hundred venous blood samples were randomly selected ...

BACKGROUND The present study determines the feasibility of generating an average arterial input function (Avg-AIF) from a limited population of patients with neck nodal metastases to be used for pharmacokinetic modeling of dynamic contrast-enhanced MRI (DCE-MRI) data in clinical trials of larger populations. METHODS Twenty patients (mean age 50 years [range 27-77 years]) with neck nodal metas...
