BACKGROUND Cetuximab is effective in platinum-resistant recurrent or metastatic squamous-cell carcinoma of the head and neck. We investigated the efficacy of cetuximab plus platinum-based chemotherapy as first-line treatment in patients with recurrent or metastatic squamous-cell carcinoma of the head and neck. METHODS We randomly assigned 220 of 442 eligible patients with untreated recurrent ...

At this research, the effect of the grazing intensity on the features of the soil seed bank in shrub lands in arid zones in Semnan province was studied. The sampling area (500 hectares) was determined including no-grazing area (un-grazed 15 years), the moderate grazing intensity and the high grazing intensity area near the close of interval each other. In each treatment of soil sampling, system...

The interaction between phytochrome photoequilibrium (phi) and photon flux in the photoregulation of anthocyanin production under prolonged irradiation was studied in seedlings of Brassica oleracea L. and Lycopersicon esculentum Mill. In cabbage, anthocyanin production increases with decreasing phi, reaching a maximum at the lowest value (phi = 0.13) used in this study; in tomato, the extent of...

The time-course of CO(2) assimilation rate and stomatal conductance to step changes in photosynthetic photon flux density (PPFD) was observed in Chrysanthemum x morifolium Ramat. ;Fiesta'. When PPFD was increased from 200 to 600 micromoles per square meter per second, the rate of photosynthetic CO(2) assimilation showed an initial rapid increase over the first minute followed by a slower increa...
