Purpose: The oxidative stress (OS) hypothesis of overtraining syndrome argues that increased production of free radicals through exercise cause muscle fatigue and damage resulting in lower athletic performance. Several studies have investigated OS immediately before and after exercise bouts in a training macrocycle. Our study aimed to compare OS of endurance athletes between a competition macrocycle and the immediate post-season recovery macrocycle. In addition, we aimed to identify athletes who experienced an unexplainable drop in athletic performance during the competition season in order to compare their OS to those who experienced no drop in performance. Methods: Fifteen members of the University of Alaska Fairbanks cross country ski team volunteered for this study. Blood samples were taken in early February (“mid-season”) and late April (“post-season”). Participants completed questionnaires regarding physical activity and athletic performance at the time of the blood draws. Plasma was analyzed for 4-hydroxynonenal (HNE), nitrotyrosine, nitric oxide (NOX), and superoxide dismutase (SOD). Significance was determined by Wilcoxon and Mann-Whitney tests. Results: Participants displayed significantly higher (p Conclusion: Signs of oxidative stress and mitigation during the post-season recovery macrocycle were higher in athletes who reported experiencing a drop in athletic performance during the competition season macrocycle.

作者： Judith Totman parrish Department of Earth and Spatial Sciences University of Idaho

Research on deep-time paleoclimate involves three complex lines of inquiry:reconstructing the geography of the Earth,climate modeling,and understanding just what paleoclimate proxies are *** plate tectonics became widely accepted,most of the effort went into reconstructing the geography of the *** studies that incorporated climate proxies into the research,for example,Briden and Irving [1] did so without critiquing very deeply what those proxies might mean,which was entirely appropriate given the state of the science at that *** with the assumption that we knew,at least in general,the significance of climate proxies were additional assumptions,which remained to be tested,about climate patterns and how they changed with the changing geography.

Frontiers of Environmental Science & Engineering 2016年第5期10卷 69-81页

Air quality improvement in Los Angeles, California is reviewed with an emphasis on aspects that may inform air quality policy formulation in developing cities. In the mid-twentieth century the air quality in Los Angeles was degraded to an extent comparable to the worst found in developing cities today; ozone exceeded 600 ppb and annual average particulate matter 〈 10 μm reached -150 μg.m -3. Today＇s air quality is much better due to very effective emission controls; e.g., modem automobilcs emit about 1% of the hydrocarbons and carbon monoxide emitted by vehicles of 50 years ago. An overview is given of the emission control efforts in Los Angeles and their impact on anabient concentrations of primary and secondary pollutants： the costs and health benefits of these controls arc briefly summarized, Today＇s developing cities have new challenges that are discussed： the effects of regional pollution transport are much greater in countries with very high population densities： often very large current populations must be supplied with goods and services even while economic development and air quality concerns are addressed; and many of currently developing cities arc located in or close to the tropics where photochemical processing of pollution is expected to be more rapid than at higher latitudes. The air quality issues of Beijing are briefly compared and contrasted with those of Los Angeles, and the opportunities for co-benefits for climate and air quality improvement are pointed out.

北喜马拉雅出露一系列片麻岩穹窿,这些穹窿被形成于27.5～10Ma的淡色花岗岩侵入.淡色花岗岩的岩石类型为二云母花岗岩,它们的主量元素组成为SiO2=70.97%～74.54%、K2O+Na2O=6.27%～8.09%、K2O/Na2O=0.91～1.36及A/CNK=1.10～1.33.然而,它们在微量元素组成上呈现出较大的变化:Rb=(41～322)×10-6、Sr=(26～139)×10-6、Ba=(135～594)×10-6、(La/Yb)N=0.97～17.31、Eu/Eu=0.29～0.72.北喜马拉雅淡色花岗岩的主量元素和微量元素组成特征类似于高喜马拉雅中新世的二云母花岗岩,而在Ti、Mg、Ca、Ba含量和Rb/Sr比值上明显不同于高喜马拉雅中新世的电气石-白云母花岗岩.北喜马拉雅淡色花岗岩(87Sr/86Sr)t=0.7344～0.8503(t=10Ma),εNd(10Ma)=-12.5～-19.3,与高喜马拉雅淡色花岗岩无明显差异.在岩石成因上,北喜马拉雅和高喜马拉雅中新世淡色花岗岩均起因于构造减压作用,由此导致白云母发生脱水反应诱发高喜马拉雅结晶岩系的深熔.但北喜马拉雅淡色花岗岩形成的地质背景明显不同于高喜马拉雅淡色花岗岩,前者具有较长的时间跨度,开始形成于喜马拉雅渐新世的地壳增厚期,之后形成于中新世穹窿片麻岩的折返时期,而高喜马拉雅淡色花岗岩与中新世高喜马拉雅结晶岩系的构造挤出作用有关.因此。

Background: Tuberculosis remains a public health problem worldwide, and tuberculosis in pregnancy in particular can have effects on both mother and infant. Findings: We report a case of a 22- year-old female presenting in preterm labor at 32 weeks gestation. Her pregnancy had been complicated by hearing loss and weight loss, and at the time of delivery, she was diagnosed with tuberculous otitis media and disseminated tuberculosis. Tuberculous otitis media is a rare form of tuberculosis disease, and in this case, had consequences for mother and infant. Conclusions: Importance of suspicion for tuberculosis disease in patients presenting with atypical symptoms but epidemiologic history is emphasized.

The combined use of conventional, isotopic and geochemical techniques provides a powerful tool with which to determine sedimentary provenance, from which interpretations on Himalayan evolution and tectonics can be *** we present the results of conventional bulk\|composition petrography, single grain isotopic (Ar\|Ar white mica ages, U\|Pb ages and Sm\|Nd on monazite) and whole rock Sm\|Nd, Sr (in prep) study on the Dharamsala formation (Early to Middle Miocene molasse) of Northern India. The petrography and mica cooling ages show an abrupt shift in the provenance with higher\|grade metamorphic source\|rocks replaced by sedimentary and very low\|grade metasedimentary source\|rocks up\|section. The break in composition corresponds to the transition between the Lower and Upper members of the unit, which took place between 17 5 and 17Ma (depositional ages constrained by magnetostratigraphy, Maithani and Burbank unpublished data). This event, with all likelihood tectonic in nature, interrupted and reversed the unroofing trend well documented in the classic Dagshai\|Kasauli sandstone suite of the Indian foreland basin (Najman 2000) and continued through the Lower Dharamsala. In addition U\|Pb ages and Sm\|Nd ratios on single detrital monazite grain suggest three sources, High Himalayan Series which has been effected by the earliest Himalayan metamorphism, low\|grade or un\|metamorphosed High Himalayan equivalents and grains in the youngest sediments which carry ENd(0) values identical to the Lesser Himalayan Series.

作者提出了由近似边界确定物体边界的简易珠子链算法。该算法不仅比已有的珠子链算法和改进珠子链算法简单,而且还能满足精度要求。文中采用了二种算法:(1)均方误差准则;(2)相对位置误差。后一方法可用在不能使用均方误差准则的地方。两种方法求得的结果均一致。经大量试验和误差分析证明:加上约束条件的算法,比不加约束条件的算法要精确;第一次迭代计算所求得的结果优于其后续的计算。作者还以确定肝细胞显微图象某一线粒体的边界为实例,证明了上述论点是正确的,用简易珠子链算法改善物体的边界是行之有效的。
