        The objective of this study was to investigate the dynamic neural mobilization program on the changes in muscle activity and nerve conduction velocity (NVC) in stroke patients. The participants were sampled and randomly divided into experimental group I (n=12) who underwent arm neural mobilization and experimental group II (n=13) who underwent arm dynamic neural mobilization. As the pretest, peripheral NVC of the radial, median, and ulnar nerves were measured using the Viking Quest; the biceps brachii, brachioradialis, flexor carpi radialis, and extensor carpi radialis activities were measured with sEMG. Each intervention program consisted of 10 trials per set and three sets per session. The intervention programs were performed once daily for four weeks (four days/week). Posttest measurements were taken equally as the pretest measurements. Significant differences in peripheral NVC in all sections of the radial and median nerves and wristbelow elbow and below elbow-above elbow areas of the ulnar nerve, as well as in muscle activity of all muscles except the biceps brachii. These findings indicate that dynamic neural mobilization was effective in increasing peripheral NVC and altering the muscle activity.

        Doxorubicin has been used to treating cancers, including breast cancer, bladder cancer, and acute lymphocytic leukemia, however, few studies have investigated its anti-inflammatory activity. In this study, we used mouse spleen cells treated with lipopolysaccharide (LPS), a representative inflammatory agent to investigate the effects of doxorubicin. Specially, we investigated the effects of doxorubicin on metabolic activity, cell size, cell death, and cytokine production of LPS-treated spleen cells. Doxorubicin significantly decreased the metabolic activity, even when applied at relatively low concentrations (1.6-8 ng/mL). To investigate the potential mechanism, we measured the mitochondrial membrane potential (MMP) of the LPS-treated spleen cells using Rhodamine 123. Doxorubicin decreased MMP and cell size, and induced cell death. Furthermore, doxorubicin suppressed the production of tumor necrosis factor (TNF)-alpha, a representative cytokine, in LPS-treated spleen cells. Taken together, doxorubicin decreased metabolic activity and the production of inflammatory cytokines, while increasing the death of LPS-induced hyperactivated spleen cells. This results will enable broader application of doxorubicin, as an anti-inflammatory agent, in clinical and research fields.

        This paper defines the common features of synbiotics based on the definition of probiotics and prebiotics, and reviews the effectiveness of synbiotic food. The concept of synbiotics is defined as ‘a mixture of prebiotics and probiotics that have a beneficial effect on the host, as a dietary supplement that alters living organisms in the gastrointestinal tract and improves their survival.’ Synbiotic food contains ingredients with beneficial microbes that are expected to improve interactions between microbial and useful substances. Synbiotic foods may have anti-cancer and immune system-boosting effects. Improved digestion, healthier bowel movements, and overall increased intestinal health has been reported were reported after increasing the healthy microorganisms within the intestinal tract. In addition, depending on the type of food containing the symbiotic ingredients, more consistent weight control, improvement of cardiovascular health, and lower blood glucose levels may also be expected. Unlike previous studies, this review of synbiotics has shown that it is necessary for synergistic effects to take place among microorganisms and components to be further studied. Further research is needed on the safety and ingestion of microorganisms contained in synbiotics.

        This study examined the quality characteristics and anti-oral microbial activity of bamboo leaf jelly prepared with different 5 levels (0, 10, 20, 30, and 40%) of bamboo (Phyllostachys nigra var. henonis) leaf extract. The sugar contents of bamboo leaf jelly were increased significantly by increasing the level of bamboo leaf extract. The luminance and Hunter’s a values of the jelly samples increased with increasing bamboo leaf extract, but the 40% bamboo leaf jelly had the lowest Hunter’s b values. The hardness, adhesiveness, gumminess, and chewiness increased significantly with increasing bamboo leaf extract. Among the mechanical properties, only the flavor of the jelly with 30 and 40% bamboo leaf extract were increased significantly. The extract of bamboo leaves had strong antimicrobial activity against S. mutans, S. sobriuns, P. gingivalis, and P. intermedia at a concentration of 40%. These results suggest that bamboo leaf extract can be useful in the production of high quality jelly.

        The coupling of two semiconducting materials is an efficient method to improve photocatalytic activity via the suppression of recombination of electron-hole pairs. In particular, the coupling between two different phases of TiO2, i.e., anatase and rutile, is particularly attractive for photocatalytic activity improvement of rutile TiO2 because these coupled TiO2 powders can retain the benefits of TiO2, one of the best photocatalysts. In this study, anatase TiO2 nanoparticles are synthesized and coupled on the surface of rutile TiO2 powders using a microemulsion method and heat treatment. Triton X-100, as a surfactant, is used to suppress the aggregation of anatase TiO2 nanoparticles and disperse anatase TiO2 nanoparticles uniformly on the surface of rutile TiO2 powders. Rutile TiO2 powders coupled with anatase TiO2 nanoparticles are successfully prepared. Additionally, we compare the photocatalytic activity of these rutile-anatase coupled TiO2 powders under ultraviolet (UV) light and demonstrate that the reason for the improvement of photocatalytic activity is microstructural.

        This study was to investigate the optimal condition of mixture ratio for development of functional food ingredient from Sarcodon aspratus and rice bran. First, oBrix was measured along with extraction time. Five kinds of mixtures of Sarcodon aspratus and rice bran (10:0, 7:3, 5:5, 3:7, 0:10) were extracted in 95oC water over a one-hour period and the extraction yield was evaluated. We further evaluated β-glucan content, DPPH radical scavenging activity, ferric ion reducing antioxidant power (FRAP), total phenolic content and total flavonoids content. As a result, both Sarcodon aspratus and rice bran showed a constant oBrix after 45 minutes of extraction time. The content of β-glucan was highest in the Sarcodon aspratus and rice bran mixture with a ratio of 3:7. As the ratio of rice bran increased in all mixtures, the antioxidant capacity also increased. In conclusion, to create a functional food ingredient the optimal mixing ratio of Sarcodon aspratus to rice bran is 3:7.

        Background: The craniocervical flexion (CCF) exercise is one of the effective exercise in correcting forward head posture (FHP). However, some people with FHP achieve CCF with compensatory movements, for example, low cervical flexion using superficial neck flexors such as the sternocleidomastoid (SCM) muscle. No study has yet investigated whether a dualpressure biofeedback unit (D-PBU) method to prevent low cervical flexion would be helpful in performing pure CCF movement. Objects: The purpose of this study was to compare the effects of the CCF using D-PBU method and the traditional CCF method on the cross-sectional area (CSA) of the longus colli muscle (LCM) and the activity of SCM muscle in subjects with FHP. Methods: Twentyfour FHP subjects (male: 16, female: 8) were recruited for this study. All subjects performed CCF using two different methods: The traditional CCF method and the CCF using D-PBU method. The CSA of the LCM was measured via ultrasound, and surface electromyography was used to measure SCM muscle activity. Results: The change in CSA of the LCM was significantly larger during the CCF using D-PBU method (1.28±.09) compared with the traditional CCF method (1.19±.08) (p<.05). The SCM muscle activity using the CCF using D-PBU method (2.01±1.97 %MVIC) was significantly lower than when using the traditional CCF method (2.79±2.32 %MVIC) (p<.05). Conclusion: The CCF using D-PBU method can be recommended for increasing LCM activation and decreasing SCM muscle activity during CCF movement in subjects with FHP.

        This study was to demonstrate the comparison of immunological activity between vegetable soup made by fresh and extruded radish in in-vitro (bone marrow-derived macrophages and dendritic cells, and mouse splenocytes) and invivo models. In cell survival tests, extruded radish added to vegetable soup (EVS) and non-extruded radish added to vegetable soup powder (NEVS) were treated with bone-marrow derived macrophages, dendritic cells, and mouse splenocytes, and showed no cytotoxic effect at a dose below 1000 μg/mL. EVS treated cells had greater cell proliferation and cytokine [tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β, IL-2, interferon (INF)-γ] production when compared to the NEVS treated group. Cell surface marker (CD 80/86, MHC class I/II) expression in bone marrow-derived macrophages and dendritic cells was evenly increased in the EVS treated group. In in-vivo study, administration of EVS increased for the CD4 and CD8 T cell population in splenocyte and cytokine production (IL-2, IFN-γ, TNF-α) but not Th2 type cytokines (IL-4). Therefore, adding the extruded radish is a more effective method for vegetable soup to increase immunological activity against immune cells.
