This study was carried out to investigate the effect of roasted rice bran (RRB) on the rheological properties of bread dough. According to farinograph analysis, the consistency of the control sample was greatest. There were no significant differences in water absorption (p<0.05). Lower values of development time, stability, and time to breakdown, which were affected, by the addition of RRB, were observed for RRB-containing dough samples, compared to the control dough sample. Addition of RRB significantly increased the mixing tolerance index (MTI). According to rheofermentometer analysis, the values of H'm, $T^{\prime}_1$, and retention volume decreased with increase in the amount of RRB added. According to the rapid visco analyzer (RVA) analysis, peak viscosity, holding strength, and setback values were greater in the control than in the RRB-containing samples. The addition of RRB to the flour influenced rheological properties like fermentation volume and acidity. The total acidity increased with the increase in the amount of RRB added. The present study has indicated that there was no significant difference between the rheological properties of the control and 5% RRB-containing dough samples. Therefore, the addition of 5% RRB could be an effective way to produce functional flour bread without affecting its desirable physical properties.

Background: Chemoradiotherapy is an important treatment modality for lung cancers. The aim of this study was to investigate alterations in, as well as the interrelationship between, lung function and quality of life of patients receiving chemoradiotherapy due to locally advanced non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) limited to the thorax. Materials and Methods: The study included patients receiving definitive chemoradiotherapy for lung carcinoma. The respiratory function of the patients was assessed by measuring forced expiratory volume in 1 s per unit (FEV1) and forced expiratory volume in 1s per unit of vital capacity (FEV1/VC) before, in the middle of and after treatment. During the study, EORTC QLQ C30 and LC13 questionnaires developed by the Committee of the European Organization for Research and Treatment of Cancer (EORTC) were employed to evaluate the quality of life on the same day as respiratory function tests (RFT). Findings: The study included 23 patients in total: 19 (82.6%) diagnosed with NSCLC and 4 (17.4%) with SCLC. The average percentage FEV1 was $55.6{\pm}21.8%$ in the pre-treatment period, $56.2{\pm}19.2%$ in the middle of treatment and $60.4{\pm}22%$ at the end of treatment. The improvement in functional scores, symptom scores and general health scores during treatment was not statistically significant (P= 0.568, P= 0.734, P= 0.680, P=0.757 respectively). Conclusions: Although this study showed an improvement in respiratory function and quality of life of patients during treatment with thoracic chemoradiotherapy, no statistically significant results were obtained. While evaluating the effectiveness of treatments for lung carcinoma, the effects of treatment on respiratory function and quality of life should be considered.
The effect of baking on the physicochemical and sensory properties was investigated using a model system of sponge cakes incorporated with pine leaf powder (PLP) as a value-added food ingredient. PLP was incorporated into cake batter at 5 levels (0, 2, 4, 6, and 8%, w/w) by adding an equivalent amount based on the weight of wheat flour. After appropriate mixing, sponge cakes were baked at $170^{\circ}C$ for 30 min in an oven. The baked cakes were cooled to room temperature for 1 h prior to all measurements. The pH, moisture content, specific volume, height, volume index, and symmetry index decreased significantly with the increase in PLP content (p<0.05). On the contrary, specific gravity of the batter and baking loss increased (p<0.05). The lightness of the cakes decreased, whereas redness increased significantly with the higher amount of PLP in the formulation (p<0.05). Hardness also increased significantly (p<0.05). Both total polyphenol content and DPPH (1,1-diphenyl-2-picryl hydrazyl) radical scavenging activity increased significantly by the addition of PLP (p<0.05). The consumer acceptance test indicated that the addition of PLP up to 4% did not cause a significant unfavorable effect on the consumer acceptances in all attributes. The sponge cakes with 2-4% PLP would be recommended with respect to the overall acceptance score while taking advantage of the functional properties of PLP without sacrificing the consumer acceptability.

One-dimensional nanostructures have attracted increasing attention because of their unique electronic, optical, optoelectrical, and electrochemical properties on account of their large surface-to-volume ratio and quantum confinement effect. Vertically grown nanowires have a large surface-to-volume ratio. The vapor-liquid-solid (VLS) process has attracted considerable attention for its self-alignment capability during the growth of nanostructures. In this study, vertically aligned silicon oxide nano-pillars were grown on Si\$SiO_2$(300 nm)\Pt substrates using two-zone thermal chemical vapor deposition system via the VLS process. The morphology and crystallographic properties of the grown silicon oxide nano-pillars were investigated by field emission scanning electron microscopy and transmission electron microscopy. The diameter and length of the grown silicon oxide nano-pillars were found to be dependent on the catalyst films. The body of the silicon oxide nano-pillars exhibited an amorphous phase, which is consisted with Si and O. The head of the silicon oxide nano-pillars was a crystalline phase, which is consisted with Si, O, Pt, and Ti. The vertical alignment of the silicon oxide nano-pillars was attributed to the preferred crystalline orientation of the catalyst Pt/Ti alloy. The vertically aligned silicon oxide nano-pillars are expected to be applied as a functional nano-material.
This study investigated the quality characteristics of sponge cake by introduction of buckwheat powder (BP). Cake batter was prepared by substituting wheat flour with an equivalent amount of BP based on weight. Sponge cakes were prepared with different amounts of BP (0, 10, 20, and 30%, respectively). Their physicochemical and sensory properties were tested. The specific gravity was not affected by the addition of BP (10~30%) (p<0.05). The lightness (L value) and yellowness (b value) of the crumb significantly decreased with the increase in the BP contents (p<0.05), whereas the redness (a value) increased (p<0.05). As the increase in the amount of BP addition, the hardness, cake volume (mL), baking loss rate (%), and specific volume (mL/g) significantly decreased (p<0.05). On the contrary, the cake weight increased. In the sensory evaluation, no significant differences in terms of color, taste, texture, flavor, and overall acceptance were observed among the different amout of BP addition (0~20%) (p<0.05). Overall, the sponge cake prepared with the addition of 20% BP was recommended to use due to its advantages in functional property.

In this study, the extractable content of each parameters from angelica was confirmed using conventional solvent extraction and microwave extraction in order to extract the functional active ingredient. In addition, the functionality of active ingredients was evaluated by measuring the antioxidant activity and the flavonoids and total polyphenols of the active ingredient extracted from angelica, For the conventional solvent extraction at optimal conditions of the extraction time (2 h), ethanol/pure water volume ratio (60%), the extraction temperature ($60^{\circ}C$), 20.6 wt% of the active ingredient were extracted. Also, when using microwave extraction at optimal conditions of the microwave irradiation time (6 min), microwave intensity (600 W) and ethanol/pure water volume ratio (60 vol%) 22.8 wt% of the active ingredient were extracted. The microwave method required shorter time to complete extraction compared to that of using the conventional solvent extraction method. The antioxidant activity of active ingredients extracted from angelica was 31.46% of DPPH radical scavening activity. The flavonoid content was 14.20 mg QE/mg dw, and total polyphenol content was 11.70 mg GAE/g when using the microwave extraction process.
A study was conducted to investigate the effect of ACAMS(Autoclaved-cooled amylomaize VII) and ACNMS(Autoclaved-cooled normal maize starch) containing resistant starch(RS) on ASW (Australian wheat flour) rheology and noodle quality. The water absorption in farinograph increased with the addition of ACAMS and ACNMS, but the dough stability decreased with the addition. The ACNMS added flours showed the highest initial pasting temperature and the lowest peak viscosity in RVA. The addition of ACAMS and ACNMS were not effective on the weight and volume of cooked noodles during cooking time for 5 min. However, as the cooking time increased, noodle weight and volume were the highest in control(no RS added flour) and the lowest in ACNMS added flours. Noodle texture was evaluated using rheometer. The hardness of RS(ACAMS, ACNMS) added noodles was higher than that of control. Cohesiveness was significantly different between control and ACAMS added noodles, but the cohesiveness of ACNMS added noodles was similar to other noodles. The elasticity of ACNMS added noodles in sensory test was lower than that of control but the smoothness and overall acceptibility were higher.
Purpose: Mitochondrial disease (MD) and Duchenne muscular dystrophy (DMD) are often associated with cardiomyopathy, but the myocardial variability has not been isolated to a specific characteristic. We evaluated the left ventricular (LV) mass by echocardiography to identify the general distribution and functional changes of the myocardium in patients with MD or DMD. Methods: We retrospectively evaluated the echocardiographic data of 90 children with MD and 42 with DMD. Using two-dimensional echocardiography, including time-motion (M) mode and Doppler measurements, we estimated the LV mass, ratio of early to late mitral filling velocities (E/A), ratio of early mitral filling velocity to early diastolic mitral annular velocity (E/Ea), stroke volume, and cardiac output. A "z score" was generated using the lambda-mu-sigma method to standardize the LV mass with respect to body size. Results: The LV mass-for-height z scores were significantly below normal in children with MD ($-1.02{\pm}1.52$, P<0.001) or DMD ($-0.82{\pm}1.61$, P =0.002), as were the LV mass-for-lean body-mass z scores. The body mass index (BMI)-for-age z scores were far below normal and were directly proportional to the LV mass-for-height z scores in both patients with MD (R =0.377, P<0.001) and those with DMD (R =0.330, P=0.033). The LV mass-for-height z score correlated positively with the stroke volume index (R =0.462, P<0.001) and cardiac index (R =0.358, P<0.001). Conclusion: LV myocardial atrophy is present in patients with MD and those with DMD and may be closely associated with low BMI. The insufficient LV mass for body size might indicate deterioration of systolic function in these patients.

This study evaluated the quantitative effects of the deployment of semi-actuated signal systems using field data. For this, a semi-actuted signal system was deployed in the regional roadway network extensively. This paper investigated an operating strategy of semi-actuated signal systems for field application, and implemented the functional strategy into the standard signal controller. The performance was evaluated using three measures of effectiveness such as traffic volume, travel time, and the number of delayed vehicle. From the analysis results, traffic volume increased about 9.4% and 11.3% for morning and evening peak periods, respectively. The average travel time was reduced about 6.3% and 7.8% during morning and evening peak periods, respectively because of the expansion of bandwidths for major streets. In addition, the number of delayed vehicles was reduced about 36.4% and 23.9% for morning and evening peak periods, respectively. It is expected that the effectiveness of signal control system can be improved by incorporating a properly designed semi-actuated signal system in regional roadways with directional demand variation.
