Abstract
To investigate quantitatively the effects of stirring on protein crystallization, a new stirring system which can agitate a protein solution, approximately 100 nl, by providing Hagen-Poiseuille flow has been successfully developed. In addition, this new stirring system provides flow with a well defined pattern and velocity. Using this system, hen egg-white lysozyme was crystallized in 100-200 nl solutions while being stirred. The optimum stirring conditions for lysozyme crystals have been explored by evaluating the Reynolds (Re) number and the crystals obtained. Intermittent flow, as well as a low Re number, was found to contribute significantly to the growth of a smaller number of larger crystals.

Abstract
AIM Recent studies have indicated that reactive oxygen species (ROS) play a role in the pathogenesis of glomerular injury leading to proteinuria in nephrotic syndrome. In the present investigation, we examined the effects of the radical scavenger edaravone administered at various time points to rats with puromycin nephrosis. MATERIALS AND METHODS 35 Wistar rats were divided into five groups: treatment with puromycin aminonucleoside (PAN) alone, treatment with PAN followed by edaravone in the early period, treatment with PAN followed by edaravone administration in the late period, treatment with PAN and administration of edaravone for the whole experimental period, and untreated controls. On Days 3, 6 and 9, urinary protein excretion was measured. The levels of glomerular thiobarbituric acid-reactive substance (TBArs) were determined in all animals on Day 10. RESULTS On Day 9, rats that had been administered edaravone showed reduced urinary protein excretion and reduced glomerular TBArs. In particular, edaravone administration in the late period, during which proteinuria was most acute, had the effect of reducing the severity of proteinuria. Glomerular TBArs were suppressed to the control level. Our results indicate that edaravone exerts a protective effect in the acute phase of PAN nephrosis when administered as antioxidant therapy at the onset of proteinuria. CONCLUSIONS Edaravone can ameliorate urinary protein excretion after the onset of proteinuria in nephrotic syndrome.

Abstract
This study investigated the sagittal condylar path during protrusive and lateral excursions by analysing the actually measured jaw movement data and re-evaluated the setting of the sagittal condylar path inclination in consideration of Fischer's angle. Protrusive and lateral excursions of 10 healthy subjects were measured using a three-dimensional mandibular movement analysing system. Condylar path inclinations at the hinge-axis point and the corresponding external point laterally extending from the condyle were evaluated in the sagittal plane. Fischer's angle was defined as the difference between the sagittal condylar inclinations during protrusive and lateral excursions on the non-working side, by keeping the corresponding horizontal distance from the intercuspal position (ICP) equivalent at the incisal point. Analysis was performed at three different magnitudes of excursions, where the incisal point was located at 1, 3 and 5 mm away from the ICP. There was no significant difference in the sagittal condylar path inclination or the Fischer's angle between two condylar reference points. However, they were significantly different across the three different magnitudes of excursions for both condylar reference points, i.e. sagittal condylar path inclination (P = 0.003 for protrusive excursion, and P < 0.001 for lateral excursion respectively; two-way repeated-measures anova), and Fischer's angle (P = 0.013, two-way repeated-measures anova) became smaller as the incisal point became distant from the ICP. Moreover, 3- and 5-mm eccentric positions were included in the 95% CI where Fischer's angle equals zero and were considered to be clinically acceptable to adjust the sagittal condylar inclination on the semiadjustable articulators.
