Eight competitive cyclists [mean peak oxygen consumption, (V˙O2peak) = 65 ml · min−1 · kg−1] undertook two 60-min cycle ergometer time trials at 32°C and 60% relative humidity. The time trials were split into two 30-min phases: a fixed-workload phase and a variable-workload phase. Each trial was preceded by ingestion of either a glycerol solution [1 g ·(More)
Changes in polyamine metabolism were investigated in relation to growth of cell suspension cultures of carrot (Daucus carota, cv Chantenay). Changes in levels of the major amines putrescine and spermidine throughout the culture period correlated poorly with changes in fresh weight, but a closer correlation with the minor component spermine was observed. The(More)
This study is aimed at providing a dosimetric evaluation of the irregular motion of lung tumors due to variations in patients' respiration. Twenty-three lung cancer patients are retrospectively enrolled in this study. The motion of the patient clinical target volume is simulated and two types of irregularities are defined: characteristic and(More)
Red-light irradiation of etiolated wheat (Triticum aestivum L.) leaf protoplasts rapidly increases calcium-dependent phosphorylation in vivo of 70- and 60-kD peptides, and the phosphorylation is attenuated by simultaneous far-red light (K.M. Fallon, P.S. Shacklock, A.J. Trewavas [1993] Plant Physiology 101:1039-1045). When these protoplasts were solubilized(More)
Etiolated wheat (Triticum aestivum cv Mercia) leaf protoplasts respond to brief red-light irradiation by increasing in volume over a 10-min incubation period (M.E. Bossen, H.A. Dassen, R.E. Kendrick, W.J. Vredenberg [1988] Planta 174: 94-100). When the calcium-sensitive dye Fluo-3 was incorporated into these protoplasts, red-light irradiation initiated(More)
The purpose of this study is to investigate the interplay effect between dynamic MLC movement and tumor respiratory motion in volumetric-modulated arc therapy (VMAT)-based lung SBRT treatment delivered by the flattening filter-free (FFF) beam of a Varian TrueBeam machine. Six lung cancer patients with tumor motions ranging between 0.5-1.6 cm were recruited(More)
PURPOSE To evaluate dosimetric predictors of acute esophagitis (AE) and clinical outcome of patients with non-small-cell lung cancer (NSCLC) receiving reirradiation. METHODS AND MATERIALS Seventeen patients with NSCLC received reirradiation to the lung tumors/mediastinum, while immobilized in stereotactic body frame (SBF). CT simulation and(More)
