In terms of the structure of varieties, there was a decreasing trend for the proportion of three-line hybrid rice varieties but a rapid increase for that of two-line hybrid rice varieties. The percentage of rice varieties developed by scientific research institu- tions was decreasing but that developed by seed companies kept a rapid increase, indicating the commercial breeding conducted by seed companies has become a principal model in rice breeding. With regard to grain quality of varieties, the con- ventional rice varieties showed an increasing trend while the hybrid rice varieties had a decreasing trend in the proportion of high quality varieties, indicating hybrid rice needs improving more in grain quality in breeding programs.展开更多

METHODS:The faecal microbiota of twenty volunteers with IBS,subdivided into eight diarrhoea-predominant (IBS-D),eight constipation-predominant(IBS-C)and four mixed symptom-subtype(IBS-M)IBS patients,and fifteen control subjects,were analysed at three time-points with a set of fourteen quantitative real-timepolymerase chain reaction assays.All assays targeted 16S rRNA gene phylotypes putatively associated with IBS,based on 16S rRNA gene library sequence analysis. The target phylotypes were affiliated with Actinobac-teria,Bacteroidetes and Firmicutes.Eight of the target phylotypes had less than 95%similarity to cultured bacterial species according to their 16S rRNA gene sequence.The data analyses were made with repeated-measures ANCOVA-type modelling of the data and principle component analysis(PCA)with linear mixed-effects models applied to the principal component scores. RESULTS:Bacterial phylotypes Clostridium cocleatum 88%,Clostridium thermosuccinogenes 85%,Coprobacillus catenaformis 91%,Ruminococcus bromii-like, Ruminococcus torques 91%,and R.torques 93%were detected from all samples analysed.A multivariate analysis of the relative quantities of all 14 bacterial 16S rRNA gene phylotypes suggested that the intestinal microbiota of the IBS-D patients differed from other sample groups.The PCA on the first principal component(PC1),explaining 30.36%of the observed variation in the IBS-D patient group,was significantly altered from all other sample groups(IBS-D vs control, P=0.01;IBS-D vs IBS-M,P=0.00;IBS-D vs IBS-C, P=0.05).Significant differences were also observed in the levels of distinct phylotypes using relative values in proportion to the total amount of bacteria.A phy- lotype with 85%similarity to C.thermosuccinogenes was quantified in significantly different quantities among the IBS-D and control subjects(-4.08±0.90 vs -3.33±1.16,P=0.04)and IBS-D and IBS-M subjects (-4.08±0.90 vs-3.08±1.38,P=0.05).Furthermore,a phylotype with 94%similarity to R.torques was more prevalent in IBS-D patients'intestinal micro- biota than in that of control subjects(-2.43±1.49 vs -4.02±1.63,P=0.01).A phylotype with 93%simi- larity to R.torques was associated with control sam- ples when compared with IBS-M(-2.41±0.53 vs -2.92±0.56,P=0.00).Additionally,a R.bromii-like phylotype was associated with IBS-C patients in com- parison to control subjects(-1.61±1.83 vs-3.69± 2.42,P=0.01).All of the above mentioned phylotype specific alterations were independent of the effect of time. CONCLUSION:Significant phylotype level alterationsin the intestinal microbiotas of IBS patients were observed,further emphasizing the possible contribution of the gastrointestinal microbiota in IBS.展开更多

Notably he had introduced the unique concept of ＂emptiness＂ （gnyata） to explain the Middle Path philosophy： the philosophical meaning of ＂emptiness＂ is dependent co-arising of various elements that support the worldly experience. This study investigates how this concept is used in explaining the subjectivity of a human person and how it is used for interpreting the unique process of human existence. The discussions on subjectivity are imprecise in modern and contemporary philosophy. But Ngrjuna＇s philosophy enables us to explain subjectivity conclusively, without it having to be explained using metaphysical positions. Sunyata may introduce a new definition for the concept of non-self： not for negating the self but for caring self from the problems of life by making it centered in the Middle Path （madhyama-pratipat）, where one may naturally be able to use his wisdom （prajh） as the guiding principle： not mere knowledge （na）. Sanyat is understood using fourfold （catus.kot.i） logical analysis, not twofold analysis employed normally by other philosophers. Here, the Buddhist notion of self as the co-dependent evolution process of five aggregates （pahcaskandhas） is reinterpreted using the unique method of tetralemma （catus.kot. i）. This critique explores the Western philosophy＇s conceptions on ＂human reasoning, ＂logocentrism,＂ and the objective analytical method of modern science.＂ After careful cross examination of the rival philosophical positions, it reasons out why the ＂rationale of nature＂ is always superior to ＂human reasoning＂ and ＂logocentrism,＂展开更多

He has become a global publishing phenomenon： His books have been translated worldwide, film adaptations of his novels have been produced, and the author is the subject of a million-euro publishing deals and successive media scandals in France. The novels depict surprising forms of imaginary resources, a radiating end of the world, a post-nuclear anxiety, and depressive characters. Houellebecq shocks us leaving us in a world where the feelings of love, tenderness and goodwill have disappeared. The purpose of Houellebecq＇s novels is to alert about the real problems of the human society in the twenty-first century. Indeed, in the books we can easily recognize the essential features of contemporary society and the fact that the individual assumes a dehumanization process in which one has to cope with his solitude in a world of emptiness. This socio-cultural dimension is indeed the background of Houellebecq＇s novels, novels in which the protagonists seem to be wedged in a mechanism from which it is difficult to escape： reification and dehumanization on the one hand, ＂robotization＂ of love on the other. This article focuses on the analysis of the texts revealing the poignant characteristics of＂L＇Ere du vide＂ （＂The Era of Emptiness＂） as described by Gilles Lipovetsky： Loneliness, the lack of love and its replacement by sexual relations.展开更多
