RESUMO
The normal growth rates of the {110} faces of tetragonal hen egg-white lysozyme crystals, R, were measured as a function of the supersaturation σ parameter using a reflection type interferometer under µG at the International Space Station (NanoStep Project). Since water slightly evaporated from in situ observation cells during a long-term space station experiment for several months, equilibrium temperature T(e) changed, and the actual σ, however, significantly increased mainly due to the increase in salt concentration C(s). To correct σ, the actual C(s) and protein concentration C(p), which correctly represent the measured T(e) value in space, were first calculated. Second, a new solubility curve with the corrected C(s) was plotted. Finally, the revised σ was obtained from the new solubility curve. This correction method successfully revealed that the 2.8% water was evaporated from the solution, leading to 2.8% increase in the C(s) and C(p) of the solution.

PURPOSE: To investigate the usefulness of MRI for predicting pelvic control (PC) of cervical cancer treated with radiation therapy (RT). MATERIALS AND METHODS: Forty-four cervical cancer patients treated with definitive RT were retrospectively analyzed. MRIs were completed before and after RT, and the longest diameter (LD) of the residual tumor was measured on post-RT MRI. Pathologic evaluation for residual tumor was also performed. Therapeutic response was assessed using MRI. Median follow-up time for the 44 patients was 34 months. The correlations between PC rate, MRI, and pathological findings were investigated. RESULTS: The 3-year PC rates of LD = 0 cm (n = 23) after RT, 0 < LD
