Abstract: The aim of the present study is to investigate the effects of Monascus fermentation on the aroma pattern of semi-dried grass carp. Semi-dried fish was fermented using Monascus purpureus GDMCC3.439. The volatile flavor substances present in fresh fish, semi-dry fish and Monascus fermented semi-dried fish were compared by simultaneous distillation and extraction combined with gas chromatograph-mass spectrometer (GC-MS). The results showed that alcohols, aldehydes and ketones were the main components of the flavor of the unfermented and fermented semi-dried grass crap. Monascus fermentation could significantly affect the volatile flavor substances of semi-dried grass carp. Moreover, the processing of semi-dried fish fermented by Monascus could not only effectively improve the fishy smell of fresh fish, but also make up for the defect of the pickled flavor of semi-dried fish. Eighteen of the main volatile components in semi-dried fish

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0102320
Abstract: Background The epidemiology of Functional abdominal bloating (FAB) and its impact on health-related quality of life (HRQoL) in Chinese people remains unclear. Methods Randomised, stratified, multi-stage sampling methodology was used to select a representative sample of the general population from five cities in China (n = 16,078). All respondents completed the modified Rome II questionnaire; 20% were asked to complete the 36-item Short Form (SF-36). The associated factors of FAB were analyzed. The effects of FAB on HRQoL were estimated with gender stratification using propensity score techniques in 20% subsample. Results Overall, 643 individuals (4.00%) had FAB and it was more prevalent in males than in females (4.87% vs. 3.04%, P<0.001). For males, self-reported history of dyspepsia was most strongly associated with FAB (OR = 2.78; 95% CI: 1.59, 4.72). However, the most strongly associated factor was self-reported health status for females (moderate health vs. good health: OR = 2.06, 95% CI: 1.07, 3.96. P = 0.030; poor health vs. good health: OR = 5.71, 95% CI: 2.06, 15.09). Concerning HRQoL, FAB was found to be related to two domains: role limitation due to physical problems (P = 0.030) and bodily pain (P<0.001) in females. While, in males, there were significant differences in multiple domains between those with and without FAB. Conclusion The prevalence of FAB in China was lower than previous reports. Males who had ever been diagnosed with dyspepsia and females who were in a poor self-reported health status were correlated with a higher prevalence of FAB. FAB affected only physical health in females, but impaired both physical and mental health in males.

Rui Wang, Cheng Wu, Yanfang Zhao, Xiaoyan Yan, Xiuqiang Ma, Meijing Wu, Wenbin Liu, Zheng Gu, June Zhao, Jia He
BMC Public Health , 2008, DOI: 10.1186/1471-2458-8-292
Abstract: A total of 1034 subjects were randomly sampled using a stratified multiple-stage sampling method in Shanghai. Demographic information was collected, and SF-36 was used to measure HRQL.Internal reliability coefficients were greater than 0.7 in six of the eight SF-36 dimensions, except social function and mental health. Intraclass correlation coefficients ranged from 0.689 to 0.972. Split-half reliability coefficients were higher than 0.9 in five SF-36 dimensions. Validity was assessed by factor analysis and correlation analysis. Our results were basically in accordance with the theoretical construction of SF-36. The average scores of most SF-36 dimensions were higher than 80. The primary influencing risk factors of HRQL included chronic diseases, age, frequency of activities, and geographical region, which were identified using multivariate stepwise regression.Overall, HRQL in the population of Shanghai is quite good. The Mandarin version of SF-36 is a valid and reliable tool for assessing HRQL.Conception of health has been changed with the development of medicine and medical sciences since 1970's. Health is defined as a dynamic state of human wellbeing characterized by a physical, mental, and social potential which satisfies the demands of a life corresponding to age, culture, and personal responsibility, and not merely the absence of disease or infirmity. Health related quality of life (HRQL) is an individual's satisfaction or happiness with the dimensions of life insofar as they affect or are affected by "health" as defined above. HRQL has been introduced to assess people's health status. To date, a number of questionnaires have been developed to evaluate HRQL, and the 36-item Short Form Health Survey (SF-36) is the most commonly used one.SF-36 was developed from the Medical Outcomes Study or RAND Health Insurance Experiment [1]. It is a short-form derived from a larger 149-item instrument and is more precise than its predecessor, SF-20 [2]. SF-36 has been proven

Abstract: Plant volatile organic compounds (Biogenic Volatile Organic compounds, referred BVOCs) have a significant impact on the atmospheric environment, air quality and human health. This experiment takes Acer truncatum flowers as the research object, uses solid-phase micro-extraction combine GC-MS (SPME-GC-MS) to detect the main component of volatiles released by the flowers from 10 individual trees of Acer truncatum (Acer truncatum Bunge). The results showed that 37 kinds of volatiles were detected and they are belonged to four types organic compouds, such as terpenoids, alcohols, ketones, esters. According to the analysis of the main components of Acer truncatum flower volatiles includes Fluorene, 4,8 -Dimethyl-1,3 (E), 7-Nonene, (cis, trans)-2,6-Dimethyl-2,4,6-triene-Partenkirchen, Myrcene, Basil hexene, 3-Carene, (E)-Basil, Camphene, Caryophyllene, Linalool, α-Terpinolene, O-cymene, 3-Vinyl-1,2-dimethyl-1, Eucalyptus alcohols and Alcohol vinegar-12. However, there were no significant differences between individual trees in terms of obscure material O-cymene, Eucalyptus alcohols, Alcohol vinegar-12, as well as the significant differences in terms of remaining volatiles.
Insulin-like growth factor-1 in myocardial tissue: interaction with tumor necrosis factor
Meijing Wang, Ben Tsai, John W Brown, Daniel R Meldrum
Critical Care , 2003, DOI: 10.1186/cc2387
Abstract: Insulin-like growth factor (IGF)-1 is a well characterized growth factor for a variety of cells and plays a role in the regulation of myocardial structure and function. There is evidence that IGF-1 improves cardiac performance and muscle survival in heart subjected to ischemia/reperfusion [1,2]. Therefore, elucidating the IGF-1 signaling pathways, especially in relation to cell survival, may help to promote the potential use of IGF-1 in the treatment of heart disease.Using an ex vivo murine model, Davani and coworkers [1], in this issue of Critical Care, demonstrate that IGF-1 confers cardiac protection from reperfusion injury via mitochondria-dependent mechanisms. Because of its vital role in myocardial energy production, the quantity of functional mitochondria is essential to myocardial activity and health. Davani and coworkers propose that the ratio of mitochondrial DNA (mtDNA) to nuclear DNA (nDNA), which is increased during ischemia and reduced with reperfusion, is a very sensitive marker of cardiac injury. They then use the mtDNA : nDNA ratio to demonstrate that IGF-1, which prevents the reduction in mtDNA : nDNA ratio that occurs during reperfusion, confers myocardial cytoprotection. The mtDNA : nDNA ratio emphasizes the importance of mitochondria-related mechanisms in reperfusion injury, and it also provides a novel reference for evaluating cardiac injury.Two distinct forms of cell death, namely necrosis and apoptosis, are involved in the survival effect of IGF-1 in the cardiovascular system. IGF-1 not only inhibits necrosis via preservation of mitochondrial function, specifically by inhibiting membrane permeability and cytochrome C release in mitochondria, but also it reduces apoptosis through the inhibition of death signals generated by mitochondria [3].IGF-1 survival signals are mediated by binding to its receptor, the type 1 IGF receptor. This receptor is a heterotetramer containing cytosolic substrates (insulin receptor substrate [IRS], Shc, and Gab-1),

Journal of Computers , 2011, DOI: 10.4304/jcp.6.8.1634-1638
Abstract: In this paper, we apply two-stage fuzzy comprehensive evaluation of fuzzy theory to evaluate the recommendation trust vector of P2P network nodes, which fully reflects the effect of various factors on trust evaluation of the target node, at the same time, dynamically reflects the demand of different nodes in the different transaction context. So the trust evaluation result is more truthful and reliable. And applying fuzzy comprehensive evaluation to evaluate trust vector can better embody fuzziness and subjectivity of trust itself. Finally,

Journal of Agricultural Science , 2011, DOI: 10.5539/jas.v3n3p196
Abstract: The aim of this study was to test the effects of film mulching treatment on aroma components of pineapple fruits. In this present study, the pineapple fruits of treatment and control (open field) were harvested twice (in winter and summer, respectively) to detect the aroma components. The results indicated that esters and alkenes were the main aroma components of both treatment and control pineapple fruits. There were more kinds of esters with higher total relative contents detected in the treatment fruits both harvested in winter and summer. There were fewer kinds of alkenes with lower total relative contents detected in the treatment fruits harvested in summer. There were equal kinds of alkenes detected in both treatment and control fruits harvested in winter. But the total relative content of alkenes of treatment fruits harvested in winter was lower than that of control. There was one ester containing sulfur, propanoic acid, 3-(methylthio)-, methyl ester with relative content of 1.40%, detected in the treatment fruits harvested in winter. No ester containing sulfur was detected in the control fruits harvested in winter. In the treatment fruits harvested in summer, two esters containing sulfur, propanoic acid, 3-(methylthio)-, methyl ester (2.60%) and 3-(methylthio) propanoic acid ethyl ester (1.46%) were detected. There was only one ester containing sulfur, propanoic acid, 3-(methylthio)-, methyl ester (3.01%) was detected in the control fruits harvested in summer.

Applied Computational Intelligence and Soft Computing , 2012, DOI: 10.1155/2012/593147
Abstract: Discovering access patterns from web log data is a typical sequential pattern mining application, and a lot of access pattern mining algorithms have been proposed. In this paper, we propose an improved approach of Gap-BIDE algorithm to extract user access patterns from web log data. Compared with the previous Gap-BIDE algorithm, a process of getting a large event set is proposed in the provided algorithm; the proposed approach can find out the frequent events by discarding the infrequent events which do not occur continuously in an accessing time before generating candidate patterns. In the experiment, we compare the previous access pattern mining algorithm with the proposed one, which shows that our approach is very efficient in discovering access patterns in large database. 1. Introduction The web has become an important channel for conducting business transactions and e-commerce. Also, it provides a convenient means for us to communicate with each other worldwide. With the rapid development of web technology, the web has become an important and preferred platform for distributing and acquiring information. The data collected automatically by the web and application web servers represent the navigational behavior of web users, and such data is called web log data. Web mining is a technology to discover and extract useful information from web log data. Because of the tremendous growth of information sources, increasing interest of various research communities, and the recent interest in e-commerce, the area of web mining has become vast and more interesting. It deals with data related to the web, such as data hidden in web contents, data presented on web pages, and data stored on web servers. Based on the kinds of data, there are three categories of web mining: web content mining, web structure mining, and web usage mining [1]. The Web usage data includes the data from web server access logs, proxy server logs, and browser logs. It is also known as web access patterns. Web usage mining tries to discover the access patterns from web log files. Web access tracking can be defined as web page history [2]; the mining task is a process of extracting interesting patterns in web access logs. There are so many techniques of mining web usage data including statistical analysis [3], association rules [4], sequential patterns [5–7], classification [8–10], and clustering [11–13]. Access pattern mining is a popular approach of sequential pattern mining, which extracts frequent subsequences from a sequence database [14]. Further, discovering access patterns is an

Abstract: Background Cardiac stem cells (CSCs) promote myocardial recovery following ischemia through their regenerative properties. However, little is known regarding the implication of paracrine action by CSCs in the setting of myocardial ischemia/reperfusion (I/R) injury although it is well documented that non-cardiac stem cells mediate cardioprotection via the production of paracrine protective factors. Here, we studied whether CSCs could initiate acute protection following global myocardial I/R via paracrine effect and what component from CSCs is critical to this protection. Methodology/Principal Findings A murine model of global myocardial I/R was utilized to investigate paracrine effect of Sca-1+ CSCs on cardiac function. Intracoronary delivery of CSCs or CSC conditioned medium (CSC CM) prior to ischemia significantly improved myocardial function following I/R. siRNA targeting of VEGF in CSCs did not affect CSC-preserved myocardial function in response to I/R injury. However, differentiation of CSCs to cardiomyocytes (DCSCs) abolished this protection. Through direct comparison of the protein expression profiles of CSCs and DCSCs, SDF-1 was identified as one of the dominant paracrine factors secreted by CSCs. Blockade of the SDF-1 receptor by AMD3100 or downregulated SDF-1 expression in CSCs by specific SDF-1 siRNA dramatically impaired CSC-induced improvement in cardiac function and increased myocardial damage following I/R. Of note, CSC treatment increased myocardial STAT3 activation after I/R, whereas downregulation of SDF-1 action by blockade of the SDF-1 receptor or SDF-1 siRNA transfection abolished CSC-induced STAT3 activation. In addition, inhibition of STAT3 activation attenuated CSC-mediated cardioprotection following I/R. Finally, post-ischemic infusion of CSC CM was shown to significantly protect I/R-caused myocardial dysfunction. Conclusions/Significance This study suggests that CSCs acutely improve post-ischemic myocardial function through paracrine factor SDF-1 and up-regulated myocardial STAT3 activation.
