It had a total length of 16 723 bp. As in most mammal mitochondrial genome, it contained 13 protein coding genes, two ribosome RNA genes, 22 transfer RNA genes and one control region. The base composition was 31.3% A, 26.1% C, 14.8% G and 27.8% T, respectively. The codon usage of red fox, arctic fox, gray wolf, domestic dog and coyote followed the same pattern except for an unusual ATT start codon, which initiates the NADH dehydrogenase subunit 3 gene in the red fox. A long tandem repeat rich in AC was found between conserved sequence block 1 and 2 in the control region. In order to confirm the phylogenetic relationships of red fox to other canids, phylogenetic trees were reconstructed by neighbor-joining and maximum parsimony methods using 12 concatenated heavy-strand protein-coding genes. The result indicated that arctic fox was the sister group of red fox and they both belong to the red fox-like clade in family Canidae, while gray wolf, domestic dog and coyote belong to wolf-like clade. The result was in accordance with existing phylogenetic results.展开更多

Research suggests that teacher made instructional design decisions can lead to enhanced motor skill learning. After presenting a model of evidence-based research this paper presents information that will help teachers plan and execute lessons designed to improve students＇ motor skills. Variables that impact motor skill learning in physical education including time, type of practice, content, presentation and organizational strategies, and student skill level are presented and discussed. A brief section on student attitudes, their relation to motor skill learning and to physical literacy is included. Motor skills are needed for physically literate people to enjoy lifelong physical activity. Physical education teachers and the decisions they make contribute to students＇ learning and whether the goal of physical literacy is met.展开更多

The genomic structure is a closed circular molecule with 17,853 bp in length, comprising 13 protein-coding genes, 22 transfer RNA genes（t RNAs）, 2 ribosomal RNAs（r RNAs） and a control region. The sequence has neither a gene rearrangement nor a non-coding region. The nucleotide composition is A（36. 31%）, C（21. 48%）, T（31. 20%） and G（11. 01%）, with overall AT content of 73. 61%. The phylogenetic analysis of 13 stag beetles and another three scarab beetles show that Cyclommatus vitalisi shares a close ancestry with Lucanus mazama and Lucanus fortunei.展开更多

Developing an exergaming curriculum for schools has the potential to improve balance or postural stability in children. In this study, a purposely-built exergaming center in an elementary school was used to test fourth grade students with a specially designed exergaming curriculum oriented toward improving postural stability. The program was implemented over a 6-week period, 34 min per day, 4-5 days per week. Two control groups were used： （1） a physical education （PE） class geared toward agility, balance, and coordination （ABC） improvement, and （2） a typical PE curriculum class. Exergaming students improved their postural stability significantly over a 6-week period compared to those in the typical PE class. Improvements in postural stability were also evident in the ABC class. Postural stability in the girls was better than the boys in all pre- and post-intervention tests. This study demonstrates that exergaming is a practical resource in the PE class to improve postural stability.展开更多

It is thought that MyoD and Myf5 are required for myogenic determination, while myogenin is important for terminal differentiation and lineage maintenance. To better understand the function of myogenic regulatory factors in muscle development of flounder, an important economic fish in Asia, real-time quantitative RT-PCR was used to characterize the expression patterns of MyoD, Myf5, and myogenin at early stages of embryo development, and in different tissues of the adult flounder. The results show that, MyJ5 is the first gene to be expressed during the early stages of flounder development, followed by MyoD and myogenin. The expressions ofMyf5, MyoD, and myogenin at the early stages have a common characteristic： expression gradually increased to a peak level, and then gradually decreased to an extremely low level. In the adult flounder, the expression of the three genes in muscle is much higher than that in other tissues, indicating that they are important for muscle growth and maintenance of grown fish. During embryonic stages, the expression level of MyoD might serve an important role in the balance between muscle cell differentiation and proliferation. When the MyoD expression is over 30% of its highest level, the muscle cells enter the differentiation stage.展开更多

So attention to sports participation of college students and promoting college students actively to join in sports activities has become an important part of the construction of campus culture. Universities undertake the mission to train highly qualified personnel, it should guide students to participate in various forms of physical activity related to local conditions, and we establish certain style and taste of the campus culture. This paper aims to identify the impact of college students＇ physical conditions to construction of campus culture, so as to develop and improve the main sports participation consciousness of students in sport, we hope that we can comprehensively improve the quality of university education for better college students sports activities and to create a harmonious, strong campus culture.展开更多

While national sports development, China＇ s sports begin to flourish and have achieved remarkable record. For example, in the just-concluded 2014, in the Incheon Asian Games, China has made a total score first. This shows that sports have become an important part of national development to be reckoned with. With economic development, the accelerated pace of life is by the people neglect their own physical exercise, so that declining physical fitness, health groups continues to grow. So how in the development of sports at the same time, ensure the health sciences to improve the health condition. This paper discusses this correlation.展开更多
