The frequency of sister chromatid exchange (SCE) was analyzed in bone marrow cells of 16 patients with chronic myeloid leukemia. We have compared the SCE frequency in these patients, in both chronic and blastic phases of the dis ease, to that of normal individuals. The frequency of SCE in blastic-phase chronic myeloid leukemia patients (mean, 1.86/ cell) was significantly lower than that in chr...

Many recent studies reveal that sea ice concentration (SIC) in the eastern Arctic and snow cover extent (SCE) over central Eurasia in late autumn are potential predictors of the winter North Atlantic Oscillation (NAO). We used maximum covariance analysis (MCA) to investigate the links between autumn SIC in the Barents-Kara Seas (BK) and SCE over Eurasia (EUR) with winter (DJF) sea level pressur...

The self-assembly of 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine (TPyP) on Au(111) electrodes was investigated. The adlayer structure was found to depend on the electrode potential. At positive potentials (>0.5V(SCE)), a disordered layer of TPyP is formed on the Au(111) electrode. STM images showed that the disordered molecules are immobile. At negative potentials (-0.2V(SCE)), however, the mo...

Aberrant transforming growth factor β1 (TGFβ1) signaling plays a pathogenic role in the development of vascular fibrosis. We have reported that Schisandra chinensis fruit extract (SCE), which has been used as a traditional oriental medicine, suppresses TGFβ1-mediated phenotypes in vascular smooth muscle cells (VSMCs). However, it is still largely unknown about the pharmacologic effects of SCE o...

The spatial distribution of excitement of receptors depends on the magnitude of amplitude of light integrated over the wavefront passing through the pupil as conditioned by the receptor’s acceptance lobe. Because the peripheral zones of the pupil are less efficient in eliciting visual excitation than the pupil’s centre, otherwise known as Stiles-Crawford effect of the first kind (SCE I), the sp...

We investigated whether photoreceptor function in amblyopic eyes differed from that in non-amblyopic eyes. Photoreceptor function was assessed with the optical Stiles-Crawford effect (SCE), psychophysical SCE, and foveal visual pigment density in both eyes of ten unilateral amblyopic subjects. Optical SCE and density measurements were carried out with a custom-built scanning laser ophthalmoscop...

This paper presents a high-level, visual Service Creation Environment (SCE) for web services. The SCE introduces two main concepts: services and composition templates. Composition templates are abstract descriptions of reusable compositions containing several placeholders for services. Services are verified to be compatible with the composition template when a service is mapped onto a compositi...

As aspiring respiratory physicians are aware, The Federation of Royal Colleges of Physicians of the UK (FRCPUK) has introduced Specialty Certificate Examinations (SCEs) to complement workplace-based assessments. Successful completion of the SCE in Respiratory Medicine is a prerequisite for Certificate of Completion of Training for all UK respiratory trainees whose specialist training began duri...

A brief description of chromosome aberrations and sister chromatid exchange (SCE) as cytogenetic endpoints for evaluation of DNA damaging agents is presented. Problems associated with the use of cytogenetic assays as population monitors of radiation and chemical exposures are discussed. Adequate cell sample size requirements and accurate assessment of cummulative exposure effects with increasin...

Abstract Negative attitudes of non-Singaporeans towards Singapore Colloquial English (SCE) are often used to support the “Speak Good Movement” in Singapore. This article examines spontaneous metalinguistic discourse about SCE an online Facebook group where Taiwanese migrants gather for mutual support. Based on idea that is mediated through social relation between interlocutors, this study revea...
