Color of grape berry changed a lot during ripening that might reflect the maturity of table grape. In this study, the color difference of Kyoho grape skin was analyzed by CR-400 chroma meter, and the value of L*, a* and b* were measured at different stages of maturity. The results showed that the value of L* and b* decreased along with maturity, which reflected in the color of the grape skin turning darker and bluer. In addition, the value of a* increased continuously until 80% maturation and then decreased after this stage of ripeness. Results of correlation analysis showed that the value of L*, a*, b* and maturity were highly correlative (p < 0.01). Maturity was significant negatively related to L* and b*, and positively related to a*. There was negative correlation between a* and L*, b*, while significant positive relation between L* and b*.

AbstractHere we provide evidence with an exploratory pilot study that through the use of a Gamma 40 Hz entrainment frequency, mood, memory and cognition can be improved with respect to a 9-participant cohort. Participants constituted towards three binaural entrainment frequency groups: the 40 Hz, 25 Hz and 100 Hz. Participants attended a total of eight entrainment frequency sessions twice over the duration of a 4-week period. Additionally, participants were assessed based on their cognitive abilities, mood as well as memory, where the cognitive and memory assessments occurred before and after a 5-min binaural beat stimulation. The mood assessment scores were collected from sessions 1, 4 and 8, respectively. With respect to the Gamma 40 Hz entrainment frequency population, we observed a mean improvement in cognitive scores, elevating from 75% average to 85% average upon conclusion of the experimentation at weak statistical significance ($$\alpha$$ α = 0.10, p = 0.076). Similarly, memory score improvements at a greater significance ($$\alpha$$ α = 0.05, p = 0.0027) were noted, elevating from an average of 87% to 95%. In pertinence to the mood scores, a negative correlation across all populations were noted, inferring an overall increase in mood due to lower scores correlating with elevated mood. Finally, correlation analysis revealed a stronger R$$^2$$ 2 value (0.9838) within the 40 Hz group between sessions as well as mood score when compared across the entire frequency group cohort.

Abstract Objectives Grapes are nutrient-dense, particularly in polyphenolic compounds. Previous research demonstrates benefits of whole grape and grape skin, seed, and polyphenol intake on glucose homeostasis along with other health benefits. We tested the hypothesis that intake of 4 servings per day of table grape would remediate metabolic complications in C57BL/6 J (C57) male mice fed a high-fat diet with added cholesterol and fructose diet modeling an obesogenic and diabetogenic western-style diet. Methods Groups of mice (n = 12) were provided either low-fat plus placebo diet (LF, 10% kcal fat), high-fat plus placebo (HF, 45% kcal fat), or HF plus grape powder (HF + G), for 8 weeks. Grape powder was provided at ∼10% of total energy of diet. C57 mice were provided experimental diets ad libitum. Body weights, food intake, and glucose tolerance were determined. Postmortem, inflammatory markers, cecal microbiome, and the relative concentrations of hepatic metabolites were determined. Results Fasting blood glucose was reduced in the HF + G group compared to HF-fed mice. The glucose tolerance test demonstrated that the Area Under the Curve (AUC) was also reduced. Further, a significant decrease in circulating levels of insulin were observed with HF + G supplementation. The cecal microbiome from HF + G fed mice overlapped with both the HF and LF controls, but also had characteristic shifts that were unique to grape powder consumption. Metabolomic analysis indicated grape consumption impacted inflammation and β-oxidation biomarkers indicating some remediation of hepatic pathologies associated with HF food consumption. The most significantly different hepatic metabolites included grape-derived S-methymethionine and trigonelline, while other murine hepatic metabolites significantly regulated by diet included myo-inositol and 15-HETE. Conclusions Table grape supplementation with a HF western-style diet significantly improved fasting blood glucose, circulating insulin concentrations, and HOMA-IR in C576J/Bl male mice. demonstrating an anti-diabetic effect of grape powder. At modest level of supplementation equivalent to 4 servings/day, grape powder also improved microbiome composition and changed relative levels of specific hepatic metabolites. Up-regulation of 15-HETE by diet suggests grape powder consumption may enhance PPARγ-directed gene expression, consistent with increases in glucose sensitivity observed in this study.

The temperature data from 3 meteorological stations (Kashi, Ruoqiang, and Hotan) in the South of Tarim River Basin (STRB) during 1964–2011 were analyzed by Mann-Kendall test and correlation analysis. The results from Mann-Kendall test show that the surface temperature (ST), 850 hPa temperature (T850), and 700 hPa temperature (T700) exhibited upward trends, while 300 hPa temperature (T300) revealed a downward trend. On the whole, the change rate of ST, T850, T700, and T300 was 0.26~0.46°C/10a, 0.15~0.40°C/10a, 0.03~0.10°C/10a, and −0.38~−0.13°C/10a, respectively. For the periods, ST and T850 declined during 1964–1997 and then rose during 1998–2011. T700 declined during 1964–2005 and then rose during 2006–2011, while T300 rose from 1964 to 1970s and then declined. The results from correlation analysis show that T850 and T700 positively correlated with ST (P<0.01) at the all three stations and there was a negative correlation between T300 and ST at Hotan (P<0.1), while the correlation is not significant at Kashi and Ruoqiang. The results indicate that there were gradient differences in the response of upper-air temperature (UT) to ST change.

The textural properties of grape berry flesh were evaluated with a puncture test using a total of 87 cultivars, consisting of 62 vinifera cultivars (Vitis vinifera L.) and 25 labruscana cultivars (Vitis labruscana Bailey) in order to search cultivars with crisp flesh texture for table grape breeding. Crisp texture is the most desirable texture for tableuse, and was determined as easy breakdown on mastication and firm flesh, which was measured as small deformation at the first major peak (DFP) and large maximum force (MF), respectively, in force-deformation curve of the test. For the vinifera cultivars, the mean values of DFP and MF were significantly smaller and larger in table-use cultivars than wine-use and dual-purpose cultivars, respectively. The result indicated that the vinifera wine-use and the dual-purpose cultivars had soft and non-crisp flesh. Based on the puncture tests, the cultivars with a crisp texture (2.5 mm ≥ for DFP and 0.9 N ≤ for MF) were limited to 11 vinifera table-use cultivars such as `Baladi', `Cardinal', and `Muscat of Alexandria'; and one vinifera dual-purpose cultivar (`Terbash'). The DFP was generally high in labruscana cultivars, which include table-use and dual-purpose cultivars, resulting in lacking cultivars with crisp texture among labruscana cultivars. These results indicate that the cultivars with a crisp texture were restricted to a small source within vinifera cultivars.

Purpose: The purpose of this study was to analyze the structural relationship among occupational dysfunction, stress coping, and occupational participation in healthcare workers.Method: This cross-sectional study included 601 subjects. Personal characteristics (such as age, gender, job category, opportunities for refreshment, time spent on leisure activities, and work relationships) were obtained. The Classification and Assessment of Occupational Dysfunction (CAOD), Coping Scale (CS), and Self-completed Occupational Performance Index (SOPI) were used for measurements. Descriptive statistics were analyzed, and item analysis, confirmatory factor analysis (CFA), correlation analysis, and path analysis using a structural equation modeling (SEM) were performed. CFA was performed to determine the factor structure for CAOD, CS, and SOPI. Correlation analysis was performed to determine the correlation among the factor scores of CAOD, CS, and SOPI. Path analysis was performed to examine the structural relationship among CS, SOPI, and CAOD. Results: CFA of CAOD, CS, and SOPI indicated a good fit to the predicted models. Correlation analysis of CAOD and SOPI showed a strong negative correlation and a moderate negative correlation. CAOD and emotion-focused coping showed a weak negative correlation. Path analysis suggested that SOPI (self-care, leisure, and productivity) and CS (emotion-focused coping) had a negative structural relationship with occupational dysfunction (RMSEA = 0.053, CFI = 0.958, and TLI = 0.954, χ2 = 1808.032, df = 677, p = 0.000). Conclusion: Occupational participation and stress coping can decrease occupational dysfunction. Occupational therapists can contribute to the reduction of occupational dysfunction in healthcare workers by instigating preventive occupational therapy.
