“…Similar results were reported by Ruskoné-Fourmestraux et al 18 and Koch et al 25 The poor prognosis of the combined group in our study may have been associated with more frequent T-cell phenotype and more advanced-stage disease. In three studies, 18,23,25 however, T-cell lymphomas were extremely rare. This discrepancy may correlate with the difference in the incidence of T-cell lymphoma between Western countries and Japan.…”

“…These differences may have been associated with the difference in response to treatment and patient survival. A better prognosis for gastric lymphoma compared with other localizations has been described previously, 1,4,8,11,17,18,21,24,25 although several authors showed no difference in the prognosis between gastric lymphoma and intestinal lymphoma. 5,9,[13][14][15]19,20,22,23 Few publications have shown prognostic data on patients with both gastric and intestinal involvement.…”

“…To our knowledge, 11 English studies performed a mul- tivariate analysis for prognostic factors on patients with both gastric and intestinal lymphoma. 9,[11][12][13][14][15][16]18,19,22,24 All but one 15 demonstrated an early stage to be the most significant prognostic factor for better survival. 9,[11][12][13][14]16,18,19,22,24 The next most frequent independent prognostic factor was a younger age.…”

Polymer particle agglomeration and melting causing sheet formation in fluidized bed reactors have been reported to occur during olefin polymerization. The cause of this deleterious sheet formation has not yet been established. Infrared and optical imaging were used to study the temporal temperature and size during polymerization of individual commercially active catalyst particles supported on a nylon mesh. Experiments conducted at 2100 kPa confirmed theoretical predictions that the temporal temperature rapidly attains a maximum after the start of the reaction. The magnitude of the temperature rise increases upon an increase of either reactor temperature, initial catalyst particle diameter, catalyst loading, or addition of hydrogen to the feed. The maximum transient temperature rise of single commercial catalyst particle during ethylene polymerization (7.5°C) is lower than that which can lead to local melting and polymer sheet formation. The temperature rise of particle clusters is much higher than that of individual particles, as the cluster acts as a particle with an effective diameter much larger than that of an individual particle. Thus, to circumvent polymer melting it is essential to avoid catalyst particles clustering, which may be caused by electrostatic attraction. The addition of hydrogen to the feed, often used to control polymer properties, significantly increased the initial particle temperature rise (almost double in some cases). © 2008 American Institute of Chemical Engineers AIChE J, 2008
