Context: Youth with autism spectrum disorder (ASD) demonstrates impairment in the ability to socially and emotionally relate to others that can limit participation in groups, interaction with peers, and building successful life relationships.Aims: The aim of this exploratory study was to examine the effects of a novel multimodal Mandala yoga program on social and emotional skills for youth with ASD.
Subjects and Methods: Five males with ASD attended 1 h yoga sessions, twice a week for 4 weeks. Multimodal Mandala yoga comprised 26 circular partner/group poses, color and tracing sheets, rhythmic chanting, yoga cards, and games. Treatment and Research Institute for ASD Social Skills Assessment (TSSA) scores were collected before and after the eight yoga sessions. The Modified Facial Mood Scale (MFMS) was used to observe mood changes before and after each yoga class. Paired sample t-tests were conducted on TSSA and MFMS scores to compare social and emotional differences post the 4-week camp. Narrative field notes were documented after each of the eight yoga sessions.
Results: A significant improvement from pre- to post-test was found in overall TSSA (t(4) = -5.744, P = 0.005) and on respondent to initiation (t(4) = -3.726, P = 0.020), initiating interaction (t(4) = -8.5, P = 0.039), and affective understanding and perspective taking subscales (t(4) = -5.171 P = 0.007). Youth's MFMS scores increased from 80% to 100% at the end of eight yoga sessions demonstrating a pleasant or positive mood. Thematic analysis of the narrative notes identified three key factors associated with the yoga experience: (a) enhanced mood and emotional expression, (b) increased empathy toward others, and (c) improved teamwork skills.
Conclusion: This multimodal Mandala yoga training has implication for developing positive social and emotional skills for youth with ASD.
AIM: Fructus phyllanthi tannin fraction (PTF) from the traditional Tibetan medicine Fructus phyllanthi has been found to inhibit lung and liver carcinoma in mice. In this study we investigated the anticancer mechanisms of PTF in human lung squamous carcinoma cells in vitro.METHODS: Human lung squamous carcinoma cell line (NCI-H1703), human large-cell lung cancer cell line (NCI-H460), human lung adenocarcinoma cell line (A549) and human fibrosarcoma cell line (HT1080) were tested. Cell viability was detected with MTT assay. Cell migration and invasion were assessed using a wound healing assay and a transwell chemotaxis chambers assay, respectively. Cell apoptosis was analyzed with flow cytometric analysis. The levels of apoptosis-related and metastasis-related proteins were detected by Western blot and immunofluorescence.
RESULTS: PTF dose-dependently inhibited the viability of the 3 human lung cancer cells. The IC50 values of PTF in inhibition of NCI-H1703, NCI-H460, and A549 cells were 33, 203, and 94 mg/L, respectively. PTF (15, 30, and 60 mg/L) dose-dependently induced apoptosis of NCI-H1703 cells. Treatment of NCI-H1703 and HT1080 cells with PTF significantly inhibited cell migration, and reduced the number of invasive cells through Matrigel. Furthermore, PTF dose-dependently down-regulated the expression of phosphor-ERK1/2, MMP-2 and MMP-9, up-regulated the expression of phosphor-JNK, but had no significant effect on the expression of ERK1/2 or JNK.
CONCLUSION: PTF induces cell apoptosis and inhibits the migration and invasion of NCI-H1703 cells by decreasing MPPs expression through regulation of the MAPK pathway.
