The purpose of this study was to evaluate the presence of extracapsular invasion (ECI) in positive sentinel lymph nodes (SLNs) as a predictor of disease recurrence in breast cancer. SLN biopsy was performed on 318 breasts of 316 breast cancer patients, of which 50 (15.7%) had positive SLNs. Six (12.0%) of these 50 cases had disease recurrence. The clinicopathologic features of these cases were ...

A human subject (NR) was identified whose eosinophils and neutrophils failed to respond to TNF in vitro in 29 of 33 experiments, using several biological assays. There was a response rate to TNF of 100% among 37 control subjects whose leukocytes were tested in parallel. NR serum contained an activity that inhibited the cytotoxic function of TNF- and GM-CSF-stimulated normal human eosinophils. A...

An increased availability of information technology (IT) is currently influencing decisions to monitor structures more frequently. IT is invariably used to interpret structural behaviour from monitoring data. However, engineers remain frustrated with IT results. Engineers work with incomplete knowledge, problem specific characteristics, and context dependency. Although such conditions require i...

Descriptions of receptive fields at subcortical levels of the visual system have mostly considered only the classical receptive field (CRF). A suppressive extraclassical receptive field (ECRF) has been demonstrated in relay cells within the primate lateral geniculate nucleus (LGN), but the quantitative properties and specific influence of the ECRF on the distinct magnocellular (MC), koniocellul...

Engineer–computer interaction ~ECI! is a new subdomain of human–computer interaction that is specifically tailored to engineers’ needs. ECI uses an information classification schema, provides a modular approach to task decomposition, and integrates standard engineering characteristics and working procedures into software. A software tool kit that interprets monitoring data taken from bridges wa...

This study evaluated the diagnostic performance of ultrasound elastography (USE) using carotid arterial pulsation and determined the reproducibility of USE for thyroid nodules. A total of 148 patients with 173 thyroid nodules participated. The mean elasticity contrast index (ECI) was significantly higher in malignant nodules (3.1 ± 1.5) than in benign nodules (1.7 ± 0.8) (p < 0.001). When a cut...
