草莓品种对蚜虫的抗性机制

为探讨草莓品种对蚜虫的抗性机理,以5个常规草莓品种为试材,通过调查、测定大棚内蚜虫自然发生动态和室内人工接虫后种群变化,并对草莓叶片的形态学和生理学特性与抗蚜性的关系进行了分析。结果表明章姬对蚜虫高感,丰香感,卡姆罗莎和吐德拉抗,弗吉尼亚高抗。草莓品种对蚜虫抗性与叶片背面的茸毛密度成正相关,与气孔密度呈显著负相关;与叶片的木质素含量成正比;与酚类物质含量无显著关系,与总游离氨基酸、可溶性固形物含量和水分含量无明显的线性关系。但草莓对蚜虫的抗性程度与叶片中脯氨酸、缬氨酸和胱氨酸的含量有关,特别是缬氨酸和胱氨酸在感蚜品种中的含量是抗蚜品种中的2～3倍。     

Homeowner perceptions,knowledge, and decision making regarding residential trees and natural areas in a Midwestern U.S. suburb

Residential properties in the United States represent a considerable amount of land area and contain substantial tree cover. Homeowners are important decision makers in the management of city trees because they influence the structure of urban forests, and ultimately, ecosystem service potential. To better understand the perceptions, knowledge, and practices of homeowners regarding residential tree preservation, we surveyed owners of newer versus older homes in a midwestern suburb in the United States. We found that newer homeowners were younger, wealthier, and less knowledgeable about the natural aspects of their property. During the redevelopment process, they relied on professionals to make major decisions regarding tree preservation. In contrast, owners of older homes often identified as retirees and gardeners, had more knowledge of the natural aspects of their property, and were more likely to hire an arborist. Regardless of these differences, both homeowner groups expressed equal appreciation for nature, planted, pruned, and mulched their trees, experienced tree loss, hired landscaping and tree care professionals, and communicated with the City’s Forestry Section. The results of our study further clarify the role that homeowners play in decision-making during development and highlight the important relationships that exist between homeowners and urban forest professionals.     

增施钙对镉胁迫下大蒜生理特性及品质的影响

通过营养液水培方式,探究了镉（Cd2+）对大蒜生长、光合特性、主要矿质元素吸收及品质的影响,同时研究了增施不同浓度钙（Ca2+）对镉胁迫大蒜的缓解效应。结果表明：镉胁迫处理可明显减小大蒜植株的形态指标（株高、假茎粗、假茎长、鲜质量和干质量）,降低叶片色素含量、净光合速率（Pn）、蒸腾速率（Tr）及气孔导度（Gs）,减少根中矿质元素（N、P、K、Ca、Mg）含量并增加镉积累,降低蒜薹和鳞茎（蒜头）的外观品质（鲜质量、蒜薹直径、抽薹率和鳞茎横径）及营养品质（大蒜素、可溶性糖、维生素C、游离氨基酸和可溶性蛋白）。增施钙可有效缓解镉对大蒜生长的抑制,随所增施钙浓度的提高,大蒜植株的形态指标均呈现先升后降的趋势,最大增幅分别为54.4%、26.0%、45.2%、61.4%和77.3%;同时,增施钙能显著提高镉胁迫大蒜叶片的色素含量及光合参数（Pn、Tr、Gs）,其变化趋势与形态指标相似,最大提高量分别为44.6%、36.6%、31.8%和18.4%;另外,增施适量钙增加了镉胁迫大蒜根中矿质元素含量并减少了镉积累,有效提高了蒜薹和鳞茎的外观、营养品质。

Effects of aspirin on apoptosis of homologous nasopharyngeal carcinoma cells with different radioresistance

AIM: To investigate the effects of aspirin on the apoptosis of nasopharyngeal carcinoma cell lines CNE2R and CNE2 with different radioresistance and its potential mechanism. METHODS: The effects of aspirin on the cell viability, apoptosis, and protein levels of procaspase-3, cleaved caspase-3, procaspase-9, procaspase-12, PARP and cleaved PARP, PI3K p110α, Akt, Bcl-2, Bax and p27 in the CNE2R cells and CNE2 cells were detected by the methods of MTT assay, flow cytometry and Western blot. RESULTS: Aspirin inhibited the viability of homologous nasopharyngeal carcinoma cell lines CNE2 and CNE2R (with the IC₅₀ to CNE2 cells of 6.18, 3.92 and 3.06 mmol/L for 24 h, 48 h and 72 h, respectively; and with the IC₅₀ to CNE2R cells of 7.05, 3.90 and 2.20 mmol/L for 24 h, 48 h and 72 h, respectively). After treated with aspirin for 48 h, the apoptotic rate of CNE2R cells was higher than that of CNE2 cells (P<0.05). After treated with aspirin for 48 h, the protein levels of procaspase-3, procaspase-9, procaspase-12 and PARP were decreased, the protein levels of cleaved caspase-3, cleaved PARP and p27 were increased, and the protein levels of PI3K p110α, Akt and Bcl-2/Bax were decreased. CONCLUSION: Aspirin inhibits the viability of homologous nasopharyngeal carcinoma cell lines CNE2R and CNE2 with different radioresistance. Aspirin also induces the apoptosis of CNE2 and CNE2R cells, which is more effective in CNE2R cells. The underlying mechanisms may be involved in affecting PI3K/Akt signaling pathway, Bcl-2/Bax and p27 expression.

Electrophysiological effects of lidocaine on myocardial tissue in guinea-pig left ventricular outflow tract under conditions of hypoxia,acidosis and treatment with epinephrine

AIM：To study the electrophysiological effects of lidocaine on the myocardial tissue in guinea-pig left ventricular outflow tract under the conditions of hypoxia, acidosis and treatment with epinephrine. METHODS：The action potentials of pacemaker cells in guinea-pig left ventricular outflow tract were recorded by conventional technique with intracellular microelectrodes. The effects of lidocaine on the spontaneous slow response potentials were investigated under the conditions of hypoxia, acidosis and treatment with epinephrine (EPI). RESULTS：Lidocaine markedly decreased the rate of pacemaker firing (RPF), the velocity of diastolic depolarization (VDD), the maximal rate of depolarization (Vmax), the maximal diastolic potential (MDP) and the amplitude of action potential (APA). Lidocaine also shortened the 50% and 80% of duration of action potential (APD50 and APD80). At the concentrations from 0.1 μmol/L to 10 μmol/L, the effects of lidocaine were more significant. Under the condition of hypoxia and perfusion with deprived glucose content for 15 min, VDD, RPF, Vmax, MDP and APA significantly decreased, and APD50 notably shortened. Under the condition of hypoxia, lidocaine at 1 μmol/L significantly decreased VDD, RPF, Vmax and APA as compared with the cells treated with hypoxia only. Perfusion with pH 6.8 solution for 10 min, VDD, RPF, Vmax and APA significantly decreased, MDP notably increased, and APD50 and APD80 markedly shortened. Under the condition of acidosis for 10 min, lidocaine significantly decreased VDD, RPF and Vmax, and lengthened APD50 and APD80 as compared with the cells under the condition of acidosis alone. Perfusion with EPI at 10 μmol/L for 10 min resulted in significant increases in VDD, RPF, Vmax, MDP and APA, and notable shortenings of APD50 and APD80 were also observed. Compared with 10 μmol/L EPI group, 1 μmol/L lidocaine+10 μmol/L EPI significantly reduced VDD, RPF, MDP and APA, and lengthened APD50 and APD80. CONCLUSION：Lidocaine markedly decreases the autorhythmicity of the pacemaker cells in guinea-pig left ventricular outflow tract and influences the electrophysiological effects of hypoxia, acidosis and EPI.
