background : cd117 is a thyrosin kinase receptor encoded by c-kit proto-oncogene. it is expressed during normal development in some tissues and also in a subset of neoplasia especially gastrointestinal stromal tumors   (gists). treatment with thyrosin kinase inhibitors (e.g., imatinib) is useful in cd117- positive gists. the goal of this study is to investigate the expression of cd117 in glial ...

This study investigated the relationship among blood pressure reactions to mental stress, cynical hostility, and socioeconomic status (SES) in 1,091 male public servants. Occupational grade served to index SES and cynical hostility was assessed using the Cook-Medley scale. (Cook & Medley, 1954). The magnitude of systolic, but not diastolic, blood pressure change scores to stress was positively ...

OBJECTIVE: Diabetes mellitus is one of the most common medical problems worldwide. Approximately 18% of persons over 65 years old are diabetic. WHO estimates that the prevalence rate of diabetes (4% in 1995) will increase to 5.6% in 2025. Diabetic foot problems are potentially the most preventable long–term complication for diabetes. The purpose of this study was to test the utility of the He...

PURPOSE We examined clinical and dosimetric factors as predictors of symptomatic radiation pneumonitis (RP) in lung cancer patients and evaluated the relationship between interstitial lung changes in the pre-radiotherapy (RT) computed tomography (CT) and symptomatic RP. MATERIALS AND METHODS Medical records and dose volume histogram data of 60 lung cancer patients from August 2005 to July 200...

INTRODUCTION This study reviews the differences in demographics and surgical outcomes between ectropion in Asian and non-Asian eyes. MATERIALS AND METHODS Medical records of surgically corrected ectropion cases from January 2002 to December 2006 were reviewed. Preand postoperative lid-globe apposition was graded: grade 0 with normal lid-globe apposition, grade 1 with punctal ectropion, grade ...

Introduction: Natural killer (NK) cells, of which CD56 is a specific marker, play an important role in host defense against tumors. Cancer stem cells, of which aldehyde dehydrogenase isoform 1 (ALDH1) is an immunohistochemical marker, are a group of tumorigenic cells which are involved in migration and tumor recurrences. We aimed to evaluate the expression of ALDH1 and CD56 in common salivary g...

Clinico-pathological features of 56 patients with primary gastric lymphoma were evaluated retrospectively. All cases were regraded according to a classification of Isaacson et al into high grade and low grade B-cell mucosa associated lymphoid tissue lymphoma. A third group of mixed grade was recognised in 11 patients with low grade who also had occasional areas of high grade. Low grade and mixe...

BACKGROUND The functional diffusion map (fDM) has been suggested as a tool for early detection of tumor treatment efficacy. We aim to study 3 factors that could act as potential confounders in the fDM: areas of necrosis, tumor grade, and change in tumor size. METHODS Thirty-four pediatric patients with brain tumors were enrolled in a retrospective study, approved by the local ethics committee...

A 1-D, transient mathematical model (MIX1D) has been developed to simulate the final composition distributions produced within continuous-cast slabs and blooms during an arbitrary grade transition. This work applies the model to investigate the effect of process variables on the extent of intermixing during a typical ladle change operation, where mixing occurs in both the tundish and the liquid...
