Back to Africa: Tracing Dyslexia Genes in East Africa

A sample of Swahili-speaking probands with reading difficulties was identified from a large representative sample of 1,500 school children in the rural areas of Tanzania. Families of these probands (n = 88) were invited to participate in the study. The proband and his/her siblings received a battery of reading-related tasks and performance on these tasks was recorded and treated as phenotypic data. Molecular-genetic analyses were carried out with 47 highly polymorphic markers spanning three previously identified regions of interest harboring susceptibility loci for reading difficulties: 2p, 6p, and 15q (DYX1–DYX3). The analyses revealed the involvement of these regions in the development of reading difficulties in Swahili. The linkage signals are especially pronounced for time (compared with error) indicators of reading difficulties. These findings are easily interpretable because in transparent languages such as Swahili deficits in reading are more related to the rate/speed of reading and reading-related processes than to the number of errors made. In short, the study incrementally advances the field by adding an understudied language and an understudied population to the variety of languages and populations in the field of molecular-genetic studies of reading difficulties.     

Estudio comparativo de la información elaborada a partir de mensajes que combinan imagen y texto o texto sólo

Resumen

La investigación que a continuación presentamos se proponía la comparación del contenido informativo de redacciones elaboradas por sujetos de 6° de E.G.B. a partir de mensajes codificados con imagen y lenguaje verbal escrito o codificados con lenguaje verbal escrito únicamente. Para ello aplicamos el análisis de contenido del texto que propone Meyer basado en la red semántica (una estructura que muestra la importancia que tienen las palabras e ideas de un texto y las relaciones que se establecen entre ellas). Los resultados confirman el diferente comportamiento de los sujetos experimentales ante los distintos estímulos a la hora de elaborar su información, y parecen apuntar hacia la mayor apertura del mensaje verbal escrito frente al verboicónico, más completo y cerrado (al menos para el caso que nos ocupa).     

文化自信与建设体育强国的文化基因考量

习近平同志强调指出：“加快建设体育强国,就要把握体育强国梦与中国梦息息相关的定位,把体育事业融入实现‘两个一百年’奋斗目标的大格局中去谋划。”这是新时代中国体育事业发展的使命责任与担当,同时也是中国体育事业发展的战略机遇。要实现中国体育事业由“体育大国”向“体育强国”的战略性转变,不仅需要国家经济、科技等强大的硬实力为依托,更需要文化、价值观等软实力的积淀。深入剖析和研究建设体育强国的文化基因,是坚定文化自信、道路自信的先决条件,建设体育强国的文化基因与文化自信之间相互联系、相互作用,文化自信是建设体育强国的文化深层内核,体育强国是文化自信的体育展示。坚定文化自信,为建设体育强国、健康中国提供强有力的支撑。

From ape to man: The phenomenal growth of cranial capacity and culture

What could have triggered the rapid and unprecedented expansion of brain capacity in the course of the evolution of man from one of the ape species? The development of language and associated thinking process is a strong possibility; a few other surprising activities also appear to be good candidates to have acted as the trigger.

New Technique Developed to Identify Clusters of Proteins on the Plasma Membrane of Immune Cells

<正>When our bodies are under attack from foreign organisms,such as bacteria and viruses,our immune system orchestrates a complex fight-back involving many separate parts.One important component of this response is a type of cell called the B-lymphocyte–it is this cell that is at the forefront of our

植物抗病反应分子机理

病害对植物生产的影响一直是科技工作者十分关注的问题,植物致病是指由真菌、细菌、病毒、类病毒等病原物通过机械擦伤、昆虫介导或直接插入寄主细胞后通过多种手段使植物产生的不良反应。病原和寄主的关系有亲和和不亲和两种,其中亲和则寄主表现感病,反之则抗病。而寄主的抗病机理又因为抗病基因和防卫基因的不同而不同。本文将从这些方面对植物抗病分子机理进行简要的阐述。     

Immunogenicity of formaldehyde and binary ethylenimine inactivated infectious bursal disease virus in broiler chicks

Infectious bursal disease virus （IBDV） was inactivated by two different chemicals-formaldehyde and binary ethylenimine （BEI）. Formaldehyde was used at 0. 1% and 0.2%, while BEI was used at concentrations of 0.001 and 0.002 mol/L. These four vaccines were tested for their efficiency in generating humoral immune response in different groups of broiler chicks. Both BEI-inactivated vaccines gave relatively higher antibody titers and were almost twice as efficient as formaldehyde-inactivated ones.
