Objective Anaemia is associated with higher mortality among patients with non-stroke cardiovascular conditions;less is known regarding the relationship between anaemia and mortality among patients with acute ischaemic *** Medical records were abstracted for n=3965 veterans from 131 Veterans Health Administration facilities who were admitted with ischaemic stroke in fiscal year *** values within 24 hours of admission were classified as≤27%,28%-32%,33%-37%,38%-42%,43%-47% or≥48%.Multivariate logistic regression was used to examine the relationship between anaemia and in-hospital,30-day,6-month and 1-year mortality,adjusting for age,medical comorbidities,modified Acute Physiology and Chronic Health Evaluation-III and stroke *** factors were calculated to standardise comparisons between haematocrit tier and other *** Among n=3750 patients included in the analysis,the haematocrit values were≤27%in 2.1%(n=78),28%-32% in 6.2%(n=234),33%-37%in 17.9%(n=670),38%-42% in 36.4%(n=1366),43%-47% in 28.2%(n=1059)and≥48% in 9.1%(n=343).Patients with haematocrit≤27%,compared with patients in the 38%-42% range,were more likely to have died across all follow-up intervals,with statistically significant adjusted ORs(aORs)ranging from 2.5 to *** with polycythaemia(ie,haematocrit≥48%)were at increased risk of in-hospital mortality(aOR=2.9;95%CI 1.4 to 6.0),compared with patients with mid-range admission *** differences between patients receiving and not receiving blood transfusion limited our ability to perform a propensity *** factors in the 1-year mortality model were 0.46(severe anaemia),0.06(cancer)and 0.018(heart disease).Conclusions Anaemia is independently associated with an increased risk of death throughout the first year post stroke;high haematocrit is associated with early poststroke *** anaemia is associated with 1-year mortality to a greater degree than cancer or heart dise

＜正＞ The effect of daidzein on Lactobacillus community change during in vitro fermentation ofpiglet digesta from different gastrointestinal （GI） compartment obtained at different ages was *** three conventionally raised healthy piglets from the same litter were slaughtered at age of 7, 14, 21and 28 days respectively. On each day of slaughtering, the digesta from the same GI compartment （jejunum,ileum, caecum and rectum） was pooled. The pooled digesta from each compartment was used as inocula inthree in vitro fermentation treatments: （a） VanSoest medium with 0.5g of glucose and 50ppm of daidzein;（b） VanSoest medium with 0.5g of glucose;（c） VanSoest medium *** 48 hours fermentation,

作者： Jack d. williams Michael A. Campbell Michael C. Jaskolka Tianyue Xie department of Biology Penn State Erie The Behrend College Erie USA. department of Chemistry and Biochemistry Mercyhurst University Erie USA

Artemisia vulgaris L. was collected from various regions in the USA and Montreal Canada. Gas Chromatography-Mass Spectrometry was used to identify the analytes present in the volatiles extracted by headspace solid-phase microextraction of the crushed leaves and flowers. Four distinct chemotypes are were found: One featuring the coexistence of ar-curcumene and α-zingiberene;two marked by the presence or absence of thujone and santolinatriene;and a fourth characterized by the presence of crysanthenyl acetate (40%). dNA was used to confirm the identity of Artemisia vulgaris L.

西澳大利亚州 (西澳 )大部分为年平均降水量 2 0 0～ 5 0 0mm的干旱半干旱地区。这里的农田草场面临土地退化 ,包括植被衰败、地下水上升和土壤盐渍化等 ,主要由土地开垦及过牧所致。西澳在解决此问题及草场管理、矿区植被重建方面取得许多成功经验和相关技术。 (1)盐渍化控制 :开垦土地、砍伐林木、种植小麦引起的地下水上升和次生盐渍化。大范围植树可控制地下水上升。适合植树的条件是 :a)较低的地下水含盐量 (ds/m) ;b)种植汲取地下水能力适当 (5°的缓坡上。当地科学家应用GIS、空间分析和野外监测充分研究树木生长和地下水位、含盐量、土壤质地及地面坡度的关系 ,最终确定适宜树木生长的土地景观。 (2 )草场管理 :草场因过牧、野生动物危害、杂草蔓延、大风、洪水、火灾的破坏而退化 ,当地通过以下措施促使牧场实现有效恢复和更新 :a)以草定畜 ;b)修建多种截水、集水、引水工程 ,确保墒情 ;c)在地表营造适于牧草种子着床、萌芽生长的小生境 ;d)完善的种植技术和良好的种源 ;e)坚持围栏和定点监测 ,确定植被覆盖率和复牧的时间强度。 (3)矿区植被重建和尘土控制

Treatment of RuCl2(PPh3)3 with 6-dimethylaminopentafulvene in THF in the presence of water produced(η5-C5H4CHO) RuCl(PPh3)2, which was reduced by NaBH4 to give the Ru–H···HO dihydrogen bonded complex(η5-C5H4CH2OH) RuH(PPh3)2. The dihydrogen bonded complex(η5-C5H4CH2OH)RuH(PPh3)2 could also be synthesized by the reduction of complex(η5-C5H4CHO)RuH(PPh3)2, which was obtained by the reaction of RuHCl(PPh3)3 with 6-dimethylaminopentafulvene in the presence of water. The analogous dihydrogen bonded osmium complex(η5-C5H4CH2OH)OsH(PPh3)2 was similarly prepared. Single crystal structures and dFT calculations support the presence of intra-molecular H···H interaction, with separations of around 1.9 to 2.0 .
