“用时间消灭空间”(马克思)、“脱域”(吉登斯)、“时空压缩”(哈维)、“流动空间”(卡斯特)、“地球村”(麦克卢汉)、“消失的地域”(梅罗维茨)、“赛博空间”(吉布森)……这一系列今日传播研究者耳熟能详的经典概念,大多预设这样的前提:空间和地方是新媒介技术和传播活动所跨越甚至“消灭”的对象。既然不言自明,空间也就一直处于边缘地位,甚少被经典传播研究认真对待。即便1960年代社会科学领域开始的声势浩大的空间理论思潮,很长时间里竟然“并未在传播与媒介领域得到响亮的回应”。

Purpose: This study was conducted in order to evaluate the antidiabetic effects of the aqueous extract of Lippia multiflora supplemented with magnesium on some biochemical markers of the kidneys and liver in type 2 diabetic rats. Method: 7 groups of 4 STZ-diabetic rats received separately orally Glucophage® (Glu 10 mg/kg), the plant extract (LiMAE 200 - 600 mg/kg) and the plant extract supplemented with magnesium (LiMAE-Mg 200 - 600 mg/kg). After a daily treatment of 21 days, serum biochemical parameters were assayed in 16 hr-fasted rats. Results: Diabetes caused a significant (p conclusion: The addition of magnesium to the extract of Lippia multiflora caused a greater reduction in the levels of urea, creatinine, ALT and AST increased in STZ-diabetic rats. Magnesium would therefore enhance the nephroprotective and hepatoprotective effects of Lippia multiflora in diabetic rats.

combined hepatocholangiocarcinoma is a rare and unique form of primary hepatic neoplasm, expressing histopathological and phenotypic aspects of hepatocellularcarcinoma and cholangiocarcinoma in the same tumor. Diagnosis may be performed by imaging, showing typical features of both components. We present a case of a 55-year-old woman presenting with abdominal pain and a hepatic mass. The patient underwent surgery and combined hepatocholangiocarcinoma with stem cells features was confirmed on pathological analysis. There are no signs of recurrence to date. combined hepatocholangiocarcinoma requires a preoperative diagnosis, since it is a unique entity with higher rates of local and lymph node recurrence, compared to isolated forms.

In most developing countries, particularly in the countries of sub-Saharan Africa, corn cobs are considered as waste polluting the environment during the harvest period of this cereal. In order to valorize this agricultural waste, high-performance, inexpensive and low-energy consumption magnetic bioadsorbents were prepared from corn cobs. The chemically activated raw corn cob was magnetized by coating the surface with magnetite nanoparticles. The prepared biosorbents were characterized by FT-IR, XRD, FE-SEM associated with EDX, HR-TEM, TG analysis, BET surface area analysis and XPS. The maximum specific surface area of 35.22 m2/g was reached. An attempt to use of these magnetic biosorbents for the removal of heavy metal like cr(VI) from aqueous solution was envisaged.

Recent findings: Approximately 830 women die every day worldwide as a result of complications related to pregnancy or childbirth with obstetric hemorrhage that remains a major cause of maternal morbidity and mortality. A systematic analysis by the World Health Organization [WHO] on the global causes of maternal deaths from 2003 to 2009 found that bleeding was the leading direct cause of maternal mortality followed by hypertensive disorders and sepsis. Overall, bleeding accounted for 27.1% of all maternal deaths worldwide. The need to implement strategies that mitigate the impact of bleeding in this clinical scenario is increasingly growing. Purpose of review: The purpose of this review is to propose a management strategy based on goals established through dynamic coagulation assessment. Summary: Effective management of obstetric hemorrhage requires rapid recognition, rapid response and mobilization of the multidisciplinary team. Volumetric resuscitation, hemodynamic stability, as well as the simultaneous identification and treatment of the source of bleeding and the resolution of coagulopathy in the shortest possible time remain the cornerstones of the management of Postpartum Hemorrhage (PPH).

Background: Alopecia areata (AA) is a polygenic immunemediated disorder affecting the hair follicle for which an association with human leukocyte antigen HLA-DRB1 11 has been described. Objective: Two parameters including age of onset and extent of the disease (patchy AA and AT/AU forms)- were correlatedwith the presence or absence of HLA-DRB1 11 and its alleles in 88 severe AA patients. Methods: Patients and healthy controls were typed for HLA-DR and - DQ by molecular method. Results: Among AA patients, 37.5% (a proportion rising to 72% when taking patients who began their first patch before the age of 20 years) were positive for HLADRB1 11 compared to 21.2% healthy controls (p = 0.004, RR = 2.1). DRB1 11-positive status was associated with earlier development of the first AA patch, at the mean age of 16 years compared to 27 years (p = 0.003) in DRB1 11-negative patients. Among the DRB1 11 alleles, the presence of DRB1 1104was associated with the earliest occurrence of AA. conclusion: Our data indicate that the HLA system largely through DRB1 1104 allele influences AA onset rather than extension considering patchy AA and AT/AU.

本文逐日计算了土壤的生物学活动,使用的是非洲气象站的标准气象数据、一个简单的土壤水分模型,并且使用了关于温度、土壤含水量和生物学活动之间关系的一般性假设。活动系数r_(e_clim)由日土壤湿度和温度计算得出,从而考虑了温度与湿度之间的交互作用。瑞典中部(粘壤土,无作物)r_(e_clim)的年均值标准化为1,在那里进行了最初的校准。由于土壤在储水能力和植物覆被上的差异会对蒸腾作用产生影响,所以我们选择的样地均为无作物的该土壤,这样就只包括了气候差异。瑞典r_(e_clim)值,1,相当于诸如表土中含有的谷类秸杆等的年质量亏损约50%。非洲r_(e_clim)年均值在干热地点(法亚,乍得)为1.1,温湿地点(布拉柴维尔,刚果)为4.7之间变动。肯尼亚样地的r_(e_clim)值为2.1(高海拔,Matanya)至4.1(肯尼亚西部,Ahero)。这意味着假如土壤类型和经营相同,那么必须有4.1倍于瑞典的碳输入才能将Ahero的土壤碳水平维持在瑞典水平。对每一块样地都绘制了r_(e_clim)日动态图,并讨论了年内动态差异。模拟实验表明,如果将土壤碳平衡的瑞典土壤移至肯尼亚的Ahero,30年内其土壤碳将损失41%。如果将Ahero保持碳平衡的土壤移至瑞典,30年内其土壤碳含量将增加64%。本文讨论了方法与结论的有效性,并将r_(e_clim)与其它气候指数进行了对比。本文还提出了一种对r_(e_clim)值进行粗略估计的简易方法。

The ilama tree (Annona diversifolia Saff.) is an underutilized fruit species from Mesoamerica with a noteworthy variability in southern Mexico. The present study describes differences in knowledge and appreciation of the fruit among inhabitants from different communities in Southern Mexico, as well as differences among their ilama trees. The study took place in Tierra caliente, a region located in the states of Guerrero and the State of Mexico. Interviews were administered in three different communities as an attempt to associate the natural morphologic variation of plants and locals’ knowledge and use of the tree in order to identify their implications for conservation. Data were analyzed by multivariate analysis, and the results suggest that the morphological variation of the plants and the commercial importance of ilama are well known by locals. Indigenous community inhabitants prefer and select only white pulp trees, whereas mestizo communities promote and conserve plants with white, red, purple, and blue pulp. Germplasm flow is dynamic in the region, and ilama fruit represents a different economic value for each community. Selling the fruit is the primary goal, but not specifically its conservation and promotion. Implications for in situ conservation of ilama in Mexico are discussed.
