Şehir Göstergelerinin (Ç)evrilmesi: Bir İstanbul Anlatısının Başkalaşmış Yüzleri
Bir eserde olayların geçtiği uzamın rastgele seçilmeyeceği düşünülürse, kurgusal veya gerçek uzamın temsil ettiği mekânla bağlantısı dikkat edilmesi gereken bir husustur. Ayrıca şehri konu alan eserlerde kimi zaman sadece şehrin değil, o kültüre ilişkin belli kalıp yargıların da ortaya koyulduğu bir gerçektir.

ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...

针对滨海盐渍化土壤水稻种植过程中根系生长受盐碱胁迫,导致养分利用率低的问题。采用田间试验研究了有机肥与磷肥配施对滨海盐渍化土壤水稻不同生育期根系生长、水稻产量及养分利用率的影响。试验采用双因素设计,3个碳水平:(1)C0,无碳;(2)C1:低碳,450 kg/hm2;(3)C2:高碳,900 kg/hm2;3个磷水平:(1)P0:无磷;(2)P1:低磷,P2O5 64 kg/hm2;(3)P2:高磷,P2O5 128 kg/hm2。结果表明,在水稻成熟期,低碳低磷(T5 ...

Interaction of two-component systems in Thermus thermophilus [PDF]
目前,细菌产生了许多机制来对抗抗生素药物的使用,这给细菌性疾病的药物治疗带来了巨大的威胁。细菌感知外界环境压力的其中一个机制就是运用双组分信号转导系统(TCSs)来响应外界刺激。一个TCS一般包含两个组分:组氨酸激酶(HK)和调节应答蛋白(RR)。HK可以感知各种各样的信号,并通过改变它对应的RR的磷酸化水平来调控RR的活性,大部分磷酸化的RR接下来介导转录水平的调控。由于哺乳动物体内不含TCSs,所以TCSs是新的抗生素药物开发的重要靶点。 在一个TCS中 ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...

Proteomic Response of Prorocentrum donghaiense to Phosphorus Depletion and Resupplement [PDF]
磷(Phosphorus,P)是海洋浮游植物生长的限制因子,影响海洋初级生产力。东海原甲藻(Prorocentrumdonghaiense,P.donghaiense)是引起我国近海有害藻华的主要甲藻。目前有关磷对甲藻生长影响的研究已有很多报道,但主要集中在生理生态层面,对甲藻在磷限制条件下及其补充响应的分子机理方面了解较少。 本论文以P.donghaiense为研究对象,运用基于质谱的定量蛋白质组学技术—串联质谱标记(Tandemmasstag,TMT),并结合相应的转录组数据,比较研究了P ...

Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

The effect of thyroxine on ATP-sensitive potassium channels and cardiolipin synthesis [PDF]
甲亢性心脏病(HyperthyroidHeartDisease,HHD)是甲状腺功能亢进(Hyperthyrodism)的严重并发症,严重危害患者的生命健康,但其机制尚未完全阐明。心磷脂(Cardiolipin,CL)是主要位于线粒体内膜的特殊磷脂,在维持正常的线粒体功能中具有至关重要的作用。本课题组前期研究表明甲亢小鼠心脏中心磷脂含量升高,并且心磷脂参与甲亢性心脏病的病理过程。此外,文献资料显示甲亢会引起心磷脂侧链的C18:2的丢失,同时引起侧链中多不饱和脂肪酸含量的增多 ...

Trait‐Mediated Competition for Light Underpins Plant Diversity Loss Under Eutrophication
Eutrophication often reduces plant diversity by making the ground layer darker, which reduces understory plants. In a natural alpine grassland, we added LED light beneath the canopy and saw diversity return across different nutrient treatments: with added nitrogen fertilizer, light mainly increased new species; with added phosphorus fertilizer, it ...
