Multipolarism Trumps Trump

Beijing Review 2018年第30期61卷 20-21页

作者： Marc-Stephan arnold

The United States is bent on pulling the plug on China＇s ascent since the world＇s only superpower can＇t tolerateChina＇s peaceful resurgence. But President Donald Trump＇s tariffs on foreign goods do not only affect exporting countries such as China and Germany, they also undermine the entire global economy. This is why the rest of the world must move closer together to defend free trade against an unpredictable U.S. leader.

Molecular markers of phase transition in locusts

引用

Insect Science 2006年第1期13卷 3-12页

作者： arnold DE LOOF ILSE CLAEYS GERT SIMONET PETER VERLEYEN TIM VANDERSMISSEN FILIP SAS JURGEN HUYBRECHTS Laboratory for Developmental Physiology Genomics and Proteomics Zoological Institute Leuven Belgium

The changes accompanying the transition from the gregarious to the solitary phase state in locusts are so drastic that for a long time these phases were considered as distinct species. It was Boris Uvarov who introduced the concept of polyphenism. Decades of research revealed that phase transition implies changes in morphometry, the color of the cuticle, behavior and several aspects of physiology. In particular, in the recent decade, quite a number of molecular studies have been undertaken to uncover phase-related differences. They resulted in novel insights into the role of corazonin, neuroparsins, some protease inhibitors, phenylacetonitrile and so on. The advent of EST-databases of locusts （e.g. Kang et al., 2004） is a most encouraging novel development in physiological and behavioral locust research. Yet, the answer to the most intriguing question, namely whether or not there is a primordial molecular inducer of phase transition, is probably not within reach in the very near future.

Elevated metabolic rate during passive stretching is not a sufficient aerobic warm-up

引用

Journal of Sport and Health Science 2013年第2期2卷 109-114页

作者： arnold G.Nelson Joke Kokkonen School of Kinesiology Louisiana State University Exercise & Sport Science Department Brigham Young University-Hawaii

Purpose： The purpose of this study was to determine the extent that a static stretching program could increase heart rate （HR） and oxygen consumption （VO2）, and if the increases were sufficient to serve as a warm-up for aerobic activity. Methods： The HR and VO2 of 15 male and 16 female college students were measured after either 12 min of passive static stretching （SS）, or 12 rain pseudo-stretching （PS）, which consisted of moving through the stretching positions without placing the muscles on stretch. Four different lower body stretches were used with each stretch held for 30 s before the participant moved to a different position, with the circuit being repeated four times. VO2 was determined by averaging breath-by-breath measures over the total 12 min. HR was obtained every 30 s and the 24 values were averaged. Warm-up benefit was determined from the 02 deficit accrued during 7-min cycling at 60% VOzmax. Results： HR （beats/rain, mean 4. SD） for SS （84 ± 11） was a significant （p 〈 0.05） 9% greater than PS （78 ± 12）. Similarly, VO2 （mL/min, mean 4. SD） for SS （0.53 ± 0.13） was a significant 44% greater than PS （0.38 ± 0.11）. The O2 deficit （L, mean 4, SD） for SS （0.64 ± 1.54） was not different from PS （0.72 ± 1.61）. Conclusion： These data indicate that passive static stretching increases both HR and VO2, indicating that metabolic activity can be increased without muscle activation. The magnitude of the increases, however, is not sufficient to elicit a warm-up effect.

Patient Safety: An Injectable Education

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2013年第3期3卷 36-39页

作者： arnold William Klein Geffen School of Medicine University of California Los Angeles USA

Until recently, the effects of all injectable filling agents were temporary and very rarely associated with permanent problems. In the past, the permanent injectable silicone had been used but had been so problematic that the Justice Department filed injunctions against certain physicians on behalf of the FDA. After 2000 a dangerous pattern grew in the corridors of Washington DC, where politics and money changed the face of America and the field of aesthetics to the detriment of the faces of the consumers. Industry has accomplished the approval of synthetic agents that should have never reached the market. Once injected under skin, the body cannot digest these agents and the immune system walls them off with resultant formation of nodules, which at times require surgical removal.
