OBJECTIVE: To observe the ef.ect of.transcutaneous electroacupuncture(TEA) at Neiguan(PC 6) on ref.actory vomiting in critically ill patients in intensive care(ICU) ***: Ten patients admitted in ICU and presenting vomiting ref.actory to one or more antiemetic drugs were prospectively included in the study. TEA was applied at acupoint of.Neiguan(PC6) during 30 min with a neuromuscular transmission monitor(single-twitch stimulation with 1 Hz at a constant current of.10 m A). Nausea and Vomiting were evaluated at the f.llowing intervals: immediately af.er 30 min of.TEA at Neiguan(PC 6),30 min-6h and 6-24 h. The presence of.nausea and/or vomiting throughout the observational period was def.ned as the primary end ***: The presence of.nausea or vomiting throughout the observational period was 10% at the end of.TEA, 40% between 30 min and 6 h, and50% between 30 min and 24 h(P f.ects related to ***: TEA at Neiguan(PC 6) seems ef.ective in reducing ref.actory vomiting in the patients in ICU setting, even if.larger trials are needed to def.ne optimal modalities.

Sericostaehys seandens is a monocarpic and heliophilous liana, native in tropical Af.ican f.rests. In the montane f.rests of.the Kahuzi-Biega National Park （KBNP）（East of.DR Congo）, it has been expanding very strongly f.r a decade, and is currently considered as having negative impacts on biodiversity conservation. In this paper, we test if.S. scandens dif.ers f.om three co-occurring, native, non spreading lianas （Gouania longispicata, Tacazzea apiculata and Adenia bequaertii） f.r f.nctional traits which might inf.uence plant expansion. f.r leaf.traits （SLA, dry matter content, nitrogen concentration）, S. scandens did not show extreme values compared to those of.the three other lianas. In contrast, S. scandens had much higher biomass allocation to sexual reproduction. It also dif.ers f.om the three other lianas f.r its reproductive strategy that combines both vegetative propagation and sexual reproduct/on, and propagule dispersal by wind. Moreover, S. scandens has larger leaves and a greater number of.lateral branches per unit stem length. It is argued that the particular combination of.f.nctional traits exhibited by *** may in part explain its propensity to behave as an opportunistic weed in the disturbed areas in the montane f.rests of.Kahuzi-Biega.

Aim： To f.nd an in vitro system f.r the measurement of.the androgenic ef.ects of.dif.erent extracts of.Hibiscus macranthus （Malvaceae） and Basella alba （Basellaceae）. Methods： The production of.testosterone f.om testes slices incubated in two media, either Krebs-Henseleit buf.er containing 0.5% Bovine serum albumin （BSA） or Dubecco＇s Modif.ed Eagle＇s medium-f.2 Ham nutrient mixture （DME/Ham f.2）, under a mixture of.5% CO2 in 95% air was determined either in the presence or absence of.cof.ctors and Hibiscus macranthus plus Basella alba （HMBA） extracts. Results： The testosterone production was increased in testes slices incubated in DME/Ham f.2 medium in response to the cof.ctors （49%） and aqueous extracts （34%-60% according to dilutions）. Under the same atmospheric conditions, there was no positive response of.the testes slices to either cof.ctor or HMBA extract stimulation in Krebs-Henseleit buf.er containing 0.5% BSA, In f.rther investigations related to the ef.ect of.HMBA, the DME/ Ham f.2 medium was used. The results obtained f.om the in vitro test showed that the activity was present mainly in methylene chloride and methanol, since these extracts induced an increase in testosterone production by testes slices. Conclusion： The testes slice system is suitable to be used f.r f.rther in vitro investigations of.the isolation of.androgenic bioactive components of.plants. （Asian J Androl 2006 Jan; 8： 111-114）

In this article we show that quantum physics is a straightf.rward and comprehensive consequence of.the model of.discrete space-time that we have put f.rward in [1] 08D0C9EA79f.BACE118C8200AA004BA90B02000000080000000E0000005f.05200650066003300390036003800390032003800330035000000 . We f.rst introduce the concept of.coherent domains and give a proof.of.the various postulates and principles that f.rm the basis of.one-particle quantum systems. Then we consider how spin-statistic theorem and the f.rmalism of.second quantization, that are prerequisites f.r a description of.many-particles systems, emerge f.om the model. f.nally the same f.amework suggests the idea of.rigid histories which allows an interpretation of.quantum entanglement to be proposed.

Since the mid-late Eocene, North China has been subjected to extensional stress, resulting in the f.rmation and development of.basins. The dynamic origin of.this crustal extension has long been an issue of.debate. This paper presents the results of.kinematic analyses of.f.ults obtained f.om two seperated areas in North China. In the Weihe graben situated on the southernmost margin of.the Ordos block, analyses of.f.ult kinematics were coupled with an analysis of.the basin's subsidence history. Three successive extensional tectonic phases accompaning the basin's f.rmation and development have been distinguished. The Palaeogene extension was oriented in a WNW-ESE direction; the Neogene extension in a NE-SW direction and the Pliocene-Quaternary extension in a NW-SE direction. Such changes have also been recorded by f.ult kinematics along the southern Tanlu f.ult zone. This has been demonstrated by three successive sets of.f.ult striations indicating normal dip slip resulting f.om NW-SE extension, then lef.-lateral slip with a normal component resulting f.om NE-SW extension, and right-lateral slip with a minor normal component, respectively. The kinematic history of.f.ults and their chronological evolution indicate changes in continental dynamics acting in North China over Cenozoic time.

We present a phenomenological study of.CO（1-0） and CO（2-1） emission f.om the circumstellar envelope （CSE） of.the Asymptotic Giant Branch （AGB） star RS Cnc. It reveals departures f.om central symmetry that turn out to be ef.icient tools f.r the exploration of.some of.the properties of.the CSE. We use a wind model including a bipolar f.ow with a typical wind velocity of.～8 km s^-1 that decreases to ～2 km s^-1 near the equator. This wind model is used to describe Doppler velocity spectral maps obtained by merging data collected at the IRAM Plateau de Bure Interf.rometer and Pico Veleta single dish radio telescope. Parameters describing the wind morphology and kinematics are obtained, together with the radial dependence of.the gas temperature in the domain of.the CSE probed by the CO observations. Signif.cant north-south central asymmetries are revealed by the analysis, which we quantif. using a simple phenomenological description. The origin of.such asymmetries is unclear.

The Douta permit of.Af.ican Star Resources/Thor Explorations, located in the southeast of.Senegal, in the Kédougou-Kéniéba Inlier (western part of.the West Af.ican Craton), is dominated to the East by metasedimentary f.rmations such as greywackes, shales, graphitic shales, quartzites, cherts, claystones and breccias characteristic of.the Dialé-Daléma basin. To the West, the maf.c f.rmations of.the Mako volcanic belt are the most common. Metasedimentary rocks are associated with metavolcanosedimentary terms f.und at the contact zones between the two (2) Birimian groups. These dif.erent geological f.rmations are cut by maf.c dolerite and gabbro sills and/or dykes, as well as quartz and microgranite veins. The Douta gold project is crossed f.om North to South by the MTZ (Main Transcurrent Zone), generally oriented NE-SW and becoming N-S towards the North. The permit is characterized by several shear corridors. The rocks are af.ected by brittle, brittle-ductile to ductile def.rmations. The gold mineralization is hosted by a NE-trending shear corridor called the Makosa corridor (Makosa shear zone), theref.re sub-parallel to the MTZ. It has a subvertical dip (75˚ to 85˚ to the NW). It is associated with a hydrothermal phase characterized by quartz-sericite-epidote-f.ne, disseminated pyrite and arsenopyrite ± albite ± chlorite paragenesis. These minerals testif. to the existence of.a low degree of.metamorphism (greenschist f.cies, epizonal domain) in the area. However, metamorphism reaches amphibolite f.cies in some places, particularly in the vicinity of.intrusive bodies, with the presence of.hornblende (amphiboles) and plagioclase. The gold mineralization is mainly hosted by two (2) metasedimentary lithological units: meta-greywackes and shales.
