目的婴幼儿哮喘的诊断主要基于咳嗽及喘息等临床症状,神经系统功能正常的婴幼儿当出现过度胃食管反流时也可以出现类似症状。目前并无随机对照研究来评价单独使用质子泵抑制剂或联合促动力药在婴幼儿中应用的疗效。本研究的主要目的是证实在呼吸道症状提示哮喘的婴幼儿中的确存在过度胃食管反流。其次,通过随机空白对照试验,探讨使用氨基甲酰甲基胆碱和奥美拉唑治疗过度胃食管反流可否改善呼吸道症状。方法有慢性咳嗽或喘息病史且有病史支持、pH监测异常或胃排空扫描提示胃食管反流的婴幼儿22例,随机分为4个治疗组:安慰剂+安慰剂(PP治疗组)、奥美拉唑+氨基甲酰甲基胆碱(OB治疗组)、奥美拉唑+安慰剂(OP治疗组)、氨基甲酰甲基胆碱+安慰剂(BP治疗组)。通过临床问卷调查、检查和家庭日记以及pH监测数据评估患儿上述治疗前后及奥美拉唑+氨基甲酰甲基胆碱非盲试验后的情况。结果 19例纳入数据统计。PP治疗对胃食管反流或呼吸道症状没有作用,pH监测提示胃食管反流并无减少。然而根据pH监测及家长评估,OB治疗可减少胃食管反流,同时显著减少日间咳嗽,改善呼吸,无不良反应发生。结论对于临床表现提示慢性胃食管反流相关性咳嗽的婴幼儿,使用奥美拉唑和氨基甲酰甲基胆碱治疗是可行的选择。

This paper aims to discuss how the shaping of a city, Juiz de fora, in Brazil, has resulted from the power of location of some social agents and from their disputes on the production of space. first, it introduces the concept of social production of space, emphasizing the role of social agents in urban processes. Then, it presents specific aspects of the history of Juiz de fora＂ its origins and how social agents and forces have played a significant role in shaping the built environment of the city--specially represented by main streets of the city. The paper studies how the social agents, with their different visions and goals, have influenced the process of formation and development of the city. This demonstrates the complexity of the existing relationships between the built environment and the social context that is specific to the city. Different urban forces fight for city spaces, construct and modify its territory so that their needs are fulfilled. Their strength, their experiences and efforts, and their ideas of a city are inscribed in urban landscapes; in similar ways, these are revealed by the city paths we follow here.

This study aimed to evaluate the antimicrobial activity of the extract of Libidibia ferrea L. (228.022-InPA) and a mouthwash formulation against microorganisms of the dental biofilm. The extract of Libidibia ferrea L. was prepared and formulated with an alcohol-free mouthwash. The Minimum Inhibitory Concentration—MIC was determined by microdilution and cell viability was evaluated through fluorescence. The MICs for the extract were 4.375 μg/mL (Streptococcus mutans), 3.750 μg/mL (Streptococcus oralis), 4.375 μg/mL (Lactobacillus casei). In contrast, for the mouthwash, the MICs were 6.000 μg/mL (bacteriostatic against Streptococcus mutans and bactericidal against Streptococcus oralis). In 1.250 μg/mL of the extract, the number of viable cells measured by fluorescence tests was 16.47% and 14.12% for Streptococcus mutans and Lactobacillus casei, respectively. for the mouthwash (1.000 μg/mL), 20.60% of viable cells for Streptococcus mutans, and 9.60% for Lactobacillus casei were observed. It can be concluded that the extract and its mouthwash containig Libidibia ferrea L. showed antibacterial activity against microorganisms from the dental biofilm.

Animal performance is affected by high air temperature and it is known that shade reduces the absorption of radiant temperature, and water for immersion facilitates heat loss. This study intends to find preferences of resources that contribute for the well-being of cattle and how they alterdaily behaviour. During summer, six Caracu and six Red Angus bulls were submitted to two different treatments： availability of artificial shade and water for immersion and availability of water for immersion. The categories observed were： positions （in the sun, under the shade, in the water）, posture （standing, lying down） and activities （grazing, ruminating leisure）. The behavioural patterns were recorded using the focal sampling method every 15 minutes （from 6：00 a.m. to 6：00 p.m.）. When shade and water for immersion coexists, cattle in this study prefer shade to avoid solar radiation. Both breeds had remained more time grazing, followed by ruminating in the Caracu breed, and by resting in the Red Angus breed. The Caracu breed had presented clear preference for the shade resource, but that fact was not always observed in the Red Angus breed. In hot climates, resources for defence against heat load, as shade and water for immersion improve the well-being of cattle.

Gold has been present throughout the history of mankind and used to make jewelry and coins, and recently, acquired several industrial uses. The price of gold in international market had a significant increasing, surpassing 100% in the last five years. Thereby, deposits with low levels of gold content, gold with complex associations or in a very fine particle size became exploitable again, allowing new projects and expansion of existing ones. However, for maximum process efficiency is indispensable a deep knowledge of the characteristics of these minerals and their behavior in face of beneficiation processes. Consequently, an accurate routine for mineralogical and technological characterization is essential.

根据2001～2007年期间在菲律宾境内测量的74个点的地磁场数据,利用球冠谐和、泰勒多项式两种方法建立了2005.0菲律宾及周边地区地磁基本场模型,得到了菲律宾地区X、Y、Z、D、I、H、f七个分量的分布.两种模型反映的同一地区的地磁场分布形态基本类似,只在拐点的舒缓度、等值线平滑度等方面存在区别.在8°n左右,X、H、f出现系统的拐点,同纬度的X、H、f东低西高.D、y零线分布于8°n左右呈东西展布,北侧为负,南侧为正,等值线沿经度分布的同时,在纬度上有不同程度的小起伏.Z、I空间分布呈现更加规则均匀的东西向分布特征.零线分布在7.5°n左右,零线北部是正值区域,南部是负值区域.两种模型与IGRf的差值的分布形态有很大的不同,球冠谐模型与IGRf模型差值的正负异常区域呈现正负异常相间的分布特征,且各分量的正负异常最大值分布在低纬度地区.而泰勒多项式与IGRf差值的正负异常分布却相对完整.

利用生态痕迹(ecological pootprint)评价人类对自然资本的利用,就是将资源消耗和废弃物产生与地球的再生能力进行比较。以前基于联合国统计资料的研究已经表明,人类对自然资本的利用已经超过了全球的生物承载力(biocapacity),同时还表明人类的生态痕迹有着很大的分布尺度。本研究主要针对瑞典,我们改进了生态痕迹与生物承裁力的计算方法,并且说明了如何才能将一个国家的生态痕迹应用于区域甚至流域。本研究还首次包含了农田淋溶的植物养分吸收区和家庭用水供应区。本文描述了生态痕迹这一评价方法,与别人和我们自己以前所使用的方法进行了对比,并讨论了这一方法应用的可能性和局限性。
