A new species of the genus Saussurella Bolivar 1887 from China,with a key to the species of the genus (Orthoptera: Tetrigidae)

Taxonomy of a tetrigid genus Saussurella Bolivar is reviewed. One new species, Saussurella brachycornis sp. nov. is described from China and an updated identification key to all known species of the genus is given, as well as brief comments on phylogenetic relationships and distributions of the genus.     

Aptamer and its applications in neurodegenerative diseases

Aptamers are small single-stranded DNA or RNA oligonucleotide fragments or small peptides, which can bind to targets by high affinity and specificity. Because aptamers are specific, non-immunogenic and non-toxic, they are ideal materials for clinical applications. Neurodegenerative disorders are ravaging the lives of patients. Even though the mechanism of these diseases is still elusive, they are mainly characterized by the accumulation of misfolded proteins in the central nervous system. So it is essential to develop potential measures to slow down or prevent the onset of these diseases. With the advancements of the technologies, aptamers have opened up new areas in this research field. Aptamers could bind with these related target proteins to interrupt their accumulation, subsequently blocking or preventing the process of neurodegenerative diseases. This review presents recent advances in the aptamer generation and its merits and limitations, with emphasis on its applications in neurodegenerative diseases including Alzheimer’s disease, Parkinson’s disease, transmissible spongiform encephalopathy, Huntington’s disease and multiple sclerosis.

Simulation of sea surface temperature changes in the Middle Pliocene warm period and comparison with reconstructions

The Middle Pliocene (ca 3.12–2.97 Ma) is a recent warm period in the Earth’s history. In many respects, the warmth of the Middle Pliocene is similar to the probable warm situation of the late 21st century predicted by climate models. Understanding the Middle Pliocene climate is important in predicting the future climate with global warming. Here, we used the latest reconstructions for the Middle Pliocene—Pliocene Research Interpretation and Synoptic Mapping (PRISM) version 3—to simulate the Middle Pliocene ...

农业院校学生农村就业的利与弊

在当今社会竞争如此激烈的大环境下,高校毕业生的规模又如此的庞大,就业的压力越来越大,有一种呼声:农业院校的毕业生到农村就业是唯一途径,这种声音普遍受到社会和人们的关注。其实现在的农业院校并非以前仅仅是农业专业,因经济全球化的快速发展让农业院校在专业方向的建设上也开始多元化。再且,由于现在的毕业生都是80后、90后,去农村就业有利有弊,所以农村并不是农业院校毕业生的唯一出路。     

关于西南边疆地方高校对外汉语专业师资培养的思考

根据中国西南与东盟国家文化的相异处以及东盟国家对汉语教学的具体需求、中国文学文化的教学规律,整理出有针对性的中国文学、文化教学内容,将文学与文化这两门课程对应联系起来,教学过程应着眼于学生的参与、师范技能以及文化素养的提高,通过注重习得、优化文学文化课程教学的内容和方法来提高学生的师范技能与文化素养,培养学生对中国文学、文化抱有一种积极的情感,是提高西南边疆地方高校对外汉语专业师资培养质量的有效途径。
