Holocene environmental changes and vegetation history are constructed using phytolith and macroscopic-charcoal analyses of a 23-m-deep drilling core obtained at the Senchomuta marsh in Asodani Valley, northern part of Aso caldera, SW Japan. An intra-caldera lake existed in the Asodani Valley prior to approximately 9 cal ka (calibrated 14C age). Multiple large flood events occurred during the period 8.9-8.1 cal ka and emplaced thick sandy deposits in the valley basin. Thereafter, the center of the Asodani Valley (northern part of caldera floor) changed to swampy and fluvial environments. sasa (cool-temperature dwarf bamboo) grasslands and/or forests with understory sasa covered slopes of the Asodani Valley basin between 11 and 9 cal ka. sasa phytoliths significantly increased at ca. 7.3-6.5 cal ka, but thereafter decreased. Miscanthus (Japanese pampas grass) grasslands existed continuously on the slopes. Macroscopic-charcoal particles were abundant during the last 6000 years, and the peak (6.1 cal ka) amount of charcoal particles is consistent with that of Miscanthus phytoliths. This indicates that the existence of Miscanthus grassland might be related to fire events. Inside the Asodani Valley, Phragmites (reed) became established continuously along the shore of the intra-caldera lake (prior to ca. 9 cal ka) and in subsequent marshes. Gramineae phytoliths were detected predominately through all horizons of the drilling core, whereas a small amount of arboreal phytolith was observed at most horizons. We, therefore, believe that forests existed on steep slopes such as the caldera wall where human impacts were small, although sasa and Miscanthus grasslands were maintained by human activity outside Aso caldera.

This study aimed to investigate the antistress properties of the ethanol extract of Cymbopogon schoenanthus (CSEE), growing wild in the southern part of Tunisia. The effect of extracts on H2O2-induced cytotoxicity and stress in human neuroblastoma SH-SY5Y cells. Its effect on stress-induced in ICR mice was exposed to force swim and tail suspension, in concordance with heat shock protein expression (HSP27 and HSP90), corticosterone, and catecholamine neurotransmitters level. Our results demonstrated that pretreatment of SH-SY5Y cells with CSEE at 1/2000, 1/1000, and 1/500 v/v dilutions significantly inversed H2O2-induced neurotoxicity. Moreover, CSEE treatments significantly reversed heat shock protein expression in heat-stressed HSP47-transformed cells (42°C, for 90 min) and mRNA expression of HSP27 and HSP90 in H2O2-treated SH-SY5Y. Daily oral administration of 100 mg/kg and 200 mg/kg CSEE was conducted to ICR mice for 2 weeks. It was resulted in a significant decrease of immobility time in forced swimming and tail suspension tests. The effect of CSEE on animal behavior was concordant with a significant regulation of blood serum corticosterone and cerebral cortex levels of catecholamine (dopamine, adrenaline, and noradrenaline). Therefore, this study was attempted to demonstrate the preventive potential of CSEE against stress disorders at in vitro and in vivo levels.

Alcohol/ethanol has been reported to derived necrosis and apoptosis with an oxidative stress in gastric mucosal cells. However the clear evidence for reactive oxygen species (ROS) generation by alcohol in gastric cells in vitro is none. In this study, we elucidated ethanol is an oxidative stress inducer on rat gastric epithelial cells by electron paramagnetic resonance measurement in living cells. We also confirmed whether ethanol-induced cellular ROS was derived from mitochondria or not. The results of cellular ROS determination showed that an increment of cellular ROS was shown for 15 min from exposing 1% (v/v) ethanol. Lipid peroxidation in cellular membrane also induced by 1% ethanol and the tendency is same in the results of cellular ROS determination. JC-1 stained showed the decrement of mitochondrial membrane potential. Additionally the localization of cellular ROS coincided with mitochondria. These results indicated that ethanol is not merely a necrotizing factor for gastric epithelial cells, but also an oxidative stress inducer via injured mitochondria.

This paper examines the results of economic poverty reduction modelling in selected countries 1992-2002 using the fuzzy set method (fsQCA) and the crisp set method (csQCA). The fsQCA and csQCA are the two main configurational comparative methods (CCM). This paper primarily focuses on making sensitivity assessments of the fsQCA and csQCA results. The outcomes of CCM based on the truth table algorithm are determined by the calibration of the set-relation membership score as well as the outcome variable of the interim truth table (called the consistency cutoff). Calibration of the raw data into crisp- and fuzzy-set membership scores based on theoretically and empirically grounded establishment of thresholds has been emphasised as it shapes the truth table algorithm. Thus, like previous studies of sensitivity assessment we focus on calibration. However this paper shows how to determine the balance of consistency and coverage outcomes based on various cutoff points as being highly important for a sensitivity assessment. We argue that the optimal consistency cutoff point helps us optimally determine the configurational multiple causality. The outcomes of fsQCA and csQCA are considered in relation to the balance of consistency and coverage. The robustness of the results of the truth table algorithm depends on the balance of consistency and coverage. Using poverty reduction as a dependent variate, we compare the two methods which are both useful.

La Correspondance de Marcel Proust, editee par Philip Kolb, nous fournit un moyen efficace d'evaluer les connaissances fort etendues de Proust sur la litterature et l'art. Nous avons pris dans ce but les statistiques des titres d'oeuvres et des noms d'auteurs, basses sur l'Index general de la Correspondance de Marcel Proust, qu'a edite Kazuyoshi Yoshikawa avec d'autres chercheurs japonais. Notre analyse statistique nous confirme que Proust a peu d'interet pour la litterature francaise du XVIIIe siecle, et d'autre part qu'il garde une predilection durant toute sa vie pour la litterature anglo-saxonne, d'autant que plus de la moitie des ecrivains strangers mentionnes dans sa correspondance sont anglais ou americains. On remarque d'ailleurs qu'il n'a pas moins de gout pour la poesie que pour le genre romanesque en ce qui concerne la litterature francaise du XIXe siecle avec laquelle it se familiarise le plus, tandis que la poesie anglaise, a la difference de la prose du meme pays, ne suscite chez lui, chose curieuse, aucun interet. Ce sont, en matiere de musique, des compositeurs francais qui y sont mentionnes le plus frequemment. Notre ecrivain etait engoue pourtant pour Wagner et Beethoven, musiciens typiquement germaniques. Ainsi le gout litteraire et artistique de Proust, a moitie juif, couvre-t-il une etendue tres vaste qui franchit la barriere des races (latine, germanique, anglo-saxonne, etc.)
