A column-switching high-performance liquid chromatography (HPLC) system for the determination of phosphopeptides has been developed. The method is based on the selective adsorption of phosphopeptides on a titania (TiO2) precolumn and successive HPLC separation of the phosphopeptides on an anion-exchange column with a UV detector (215 nm). The recoveries of phosphopeptides were tested using auth...

BACKGROUND The objectives of the present study were, with multidetector computed tomography (CT) as the reference method, to determine the performance of magnetic resonance imaging (MRI) and radiography for the detection of bone erosions in rheumatoid arthritis wrist bones, and to test whether measuring volumes of erosions on CT and MRI is reproducible and correlated to semiquantitative assessm...

[Purpose] It is clinically important to accurately evaluate the alignment of hindfoot alignment from the body surface in weight-bearing position. In general, measurement is carried out using a goniometer, but the measurement with goniometer requires experience, and the reliability in this measurement is also in question. Therefore, it is necessary to establish a clinical measurement method to r...

Endothelium forms the inner cellular lining of blood vessels and plays an important role in many physiological functions including the control of vasomotor tone. Cerebral endothelium is probably one of the most specific types but until recently it was impossible to determine its function. In this review, the role of cerebrovascular reactivity to L-arginine (CVR-L-Arg) for assessment of cerebral...

Backgrounds and Aims: P53 gene is regarded important in pathogenesis of different cancers. Therefore, this study aimed to investigate the frequency of p53 gene codon 72 Arg/Pro polymorphism in women suffering from breast cancer. Materials and Methods: A total of 90 patients with breast cancer and 83 matched healthy control women participated in this case-control study. Genomic DNA was extrac...

The evaluation of the Kjeldahl digestion method was investigated by comparing measured values of total nitrogen, phosphorus and potassium using three salt and catalyst mixture in Standard Kjeldahl digestion method and Salicylic acid Modification method with certified values of plant material as well as comparison was made for determination of total nitrogen from steam distillation method verses...

Objective- One of the important causes of nasal fracture is a trauma that can be diagnosed in clinical examinations and diagnostic imaging but it should be noted that radiography may show false fractures in the nose. This study evaluates the value of ultrasonography in the diagnosis of nasal fractures and compared it with plain radiography. Design- Retrospective study. Animals- 12 d...

BACKGROUND Auto-focusing is an important operation in high throughput imaging scanning. Although many auto-focusing methods have been developed and tested for a variety of imaging modalities, few investigations have been performed on the selection of an optimal auto-focusing method that is suitable for the pathological metaphase chromosome analysis under a high resolution scanning microscopic s...
