1Voluntary exercise-induced neurogenesis in the postischemic dentate gyrus is associated with spatial memory recovery from stroke显示文摘Luo, C. X. Jiang, J. Zhou, Q. G. Zhu, X. J. Wang, W. Zhang, Z. J. Han, X. Zhu, D. Y. 2007南京医科大学学报(自然科学版)2007,27,10:13
2DUCTILEBRITTLETRANSITION OF POLYCRYSTALLINE Ni_3Al WITH VARYING GRAIN SIZE显示文摘It is known that in B (un)doped Ni 3Al polycrystals, the dependence of yield strength on grain size follows the Hall Petch relationship: σ y= σ 0+ K y d -1/2 , and the slope K y can be reduced by B doping owing to the lowering of grain boundary resistance to slip transmission. If the intergranular cracking in polycrystalline Ni 3Al occurs from the microcavity along the grain boundaries, the effective external tensile stress for the propagation of the crack like microcavity along the grain boundaries can be deduced as: σ f= σ i+ K u d -1/2 , where K u reflects the effects of such factors as environment, strain rate, boron doping and the orientation of the grain boundary on the trend of intergranular cracking. For loaded polycrystalline Ni 3Al, it should be competitive between the intergranular cracking and slip transmission across the grain boundary. Therefore, comparing the varieties of both σ y and σ f with grain size, the dependence of ductile brittle transition on grain size, and the effects of the above factors on ductile brittle transition can be expected. The model also predicts that there exists a critical grain size for the ductile brittle transition of polycrystalline Ni 3Al alloys, and B doping can increase the critical grain size due to the reduction of the slope K y and the increase of K u. The reported experimental results verified the above model.G. W. Han, D. Feng and C. S. Lee  Central Iron & Steel Research Institute, Beijing 100081, China  Dept. Physical & Mater.

4中国的酸化问题——一项基于重庆—广州森林监测点研究结果的评估显示文摘中国经济的快速增长一直伴随着污染的加剧。本文在现场观测和文献研究的基础上讨论了酸性降水及其先兆的范围和影响。目前酸性降水的主要原因是二氧化硫的排放,但氮氧化物的排放也在增加。中国污染最严重地区的硫化合物沉降比东欧和中欧经受严重污染的地区要高。中国南部很多地区的土壤和土壤水看来已经被酸化。这些地区的污染已经影响了森林和其他植物的生命力,特别是在位于和靠近城市地区的地方。地表水的酸化似乎在近期不会成为主要的区域性问题,但一些地区的河流,目前虽仅接受少量的酸沉降,却对酸化显得较敏感。Hans M.

6Pathological and biochemical alterations of astrocytes in ovariectomized rats injected with D-galactose:A potential contribution to Alzheimer's disease processes显示文摘Astrocytes are implicated in the pathological changes of Alzheimer's disease. Our previous studies have demonstrated that estrogen deprivation and oxidative stress act synergistically to accelerate the progress of Alzheimer's disease. Long-term D-galactose injection combined with ovariectomy may serve as a rodent model for Alzheimer's disease. To address the potential contribution of astroglia to the Alzheimer's disease pathogenesis, we investigated pathological and biochemical alterations of astrocytes under this animal model. Ovadectomized rats injected with D-galactose for 2 weeks showed extensive localization of glial fibrillary acidic protein immunoreactive astrocytes and slightly elevated glutathione levels in the hippocampus without significant impairments in the water maze test and deficits of the cholinergic analyses, compared to the saline-injected rats. Ovariectomized rats injected with D-galactose for 6 weeks, however, exhibited degeneration of astrocytes and decreased glutathione levels in the hippocampus, accompanied with severe dysfunction of behavioral test and deficiency of cholinergic terminals. Electron microscopy further confirmed the pathological changes of astrocytes, especially in the aggregated area of synapse and brain microvessels. Consistent with degeneration of perivascular astrocytic endfeet, analysis of the horseradish peroxidase demonstrated an impairment of the blood-brain barrier permeability. These findings indicate that biochemical and pathological alterations of astrocytes may partially contribute to exacerbating neuronal deficits in the course of Alzheimer's disease. Restoring neuroprotective potential of astrocytes may be a useful therapeutic target for Alzheimer's disease and other neurodegenerative diseases.Hua, X. D. Lei, M. Ding, H. Han, Q. Y. Hu, G.

8Comparison of Leptosphaeria biglobosa-induced and chemically induced systemic resistance to L.maculans in Brassica napus显示文摘Brassica napus(cv.Madrigal)seedlings pre-treated with ascospores of Leptosphaeria biglobosa or foliar sprays of either acibenzolar-S-methyl(ASM)or menadione sodium bisulphite(MSB)were chal- lenge inoculated with L.maculans ascospores and assessed for phoma leaf spot development and tissue morphology and gene expression responses to infection.Rates of increase in phoma leaf spot area 8―21 d after challenge inoculation were significantly greater on water pre-treated plants than on plants pre-treated with L.biglobosa,ASM or MSB on both pre-treated leaves(local effect)and younger leaves without pre-treatment(systemic effect).Ninety-six h after challenge inoculation,the invasive hyphae of L.maculans were encircled by rings of necrotic mesophyll cells on leaves pre-treated with L. biglobosa,ASM or MSB but not those pre-treated with water.Quantification of transcript levels of genes commonly used as markers of the major defence signalling pathways(PDF1.2,PR-1,NPR1,APX, CHB4)0–96 h after L.maculans challenge inoculation showed expression patterns indicating prefer- ential activation of the jasmonate/ethylene pathway and involved induction of NPR1 locally and sys- temically in leaves of plants pre-treated with L.biglobosa ascospores.LIU ShengYi LIU RenHu Akinwunmi O.
