We present CCD B and V light curves,obtained in the year 2006,and a photometric solution of the low-mass ratio contact binary ASAS 021209＋2708.3. With our data we were able to determine six new times of minimum light and refine the orbital period of the system to 0.3181963 *** light curves are analyzed using the 2003 version of the Wilson-Devinney program and the analysis was performed with and without adding a spot on the surface of one star because the light curves appear to exhibit a typical O’Connell effect,with Maximum I brighter than Maximum *** results show that ASAS 021209＋2708.3 may be classified as an A-subtype W Ursae Majoris system with a small mass ratio q=0.1889,a large over-contact degree of f= 0.587,a very small difference between the component temperatures of Δ T=53 K and an orbital inclination of i=81°.It is known that deep（f50%） ,low-mass ratio（q0.25） overcontact binary stars are a very important resource for understanding the phenomena of Blue Straggler/FK Com-type *** formations of Blue Straggler stars and FK Com-type stars are unsolved problems in stellar *** of the possible explanations for their formation is from the coalescence of W UMa-type overcontact binary *** absolute dimensions of ASAS 021209＋2708.3 are estimated and its dynamical evolution is inferred.

We present the results of our study of the eclipsing binary systems CSS J112237.1+395219,LINEAR 1286561 and LINEAR 2602707 based on new CCD B,V,Rcand Iccomplete light *** ultra-short period nature of these stars,as reported by Drake et al.,is confirmed and the system’s periods are *** light curves were modeled using the 2003 version of the Wilson-Devinney *** necessary,cool spots on the surface of the primary component were introduced to account for asymmetries in the light *** a result,we found that CSS J112237.1+395219 is a W UMa type contact binary system belonging to W subclass with a mass ratio of q=1.61 and a shallow degree of contact of 14.8%where the primary component is hotter than the secondary one by 500 *** 1286561 and LINEAR2602707 are detached binary systems with mass ratios q=3.467 and q=0.987 *** detached systems are low-mass M-type eclipsing binaries with similar *** marginal contact,fill-out factor and temperature difference between components of CSS J112237.1+395219 suggest that this system may be at a key evolutionary state predicted by thermal relaxation oscillation(TRO)*** the estimated absolute parameters,we conclude that our systems share common properties with other ultrashort period binaries.

World Journal of Gastroenterology 2014年第28期20卷 9361-9373页

Cachexia is frequently described in patients with pancreatic ductal adenocarcinoma (PDAC) and is associated with reduced survival and quality of life. Unfortunately, the therapeutic options of this multi-factorial and complex syndrome are limited. This is due to the fact that, despite extensive preclinical and clinical research, the underlying pathological mechanisms leading to PDAC-associated cachexia are still not fully understood. Furthermore, there is still a lack of consensus on the definition of cachexia, which complicates the standardization of diagnosis and treatment as well as the analysis of the current literature. In order to provide an efficient therapy for cachexia, an early and reliable diagnosis and consistent monitoring is required, which can be challenging especially in obese patients. Although many substances have been tested in clinical and preclinical settings, so far none of them have been proven to have a long-term effect in ameliorating cancer-associated cachexia. However, recent studies have demonstrated that multidimensional therapeutic modalities are able to alleviate pancreatic cancer-associated cachexia and ultimately improve patients’ outcome. In this current review, we propose a stepwise and pragmatic approach to facilitate and standardize the treatment of cachexia in pancreatic cancer patients. This strategy consists of nutritional, dietary, pharmacological, physical and psychological methods.

Running at altitude is gaining greater popularity but it may expose participants to the risk of acute mountain sickness (AMS). The study investigated electroencephalographic (EEG) changes and eventual symptoms suggestive of AMS in 5 well-trained lowland native male runners (average age, 38.2 ? 4.6 years;VO2 peak 61.4 ? 2.7 mL?kg–1?min–1 at sea level;best marathon performance at sea level under 3 hours), who completed a marathon at 4300 m altitude. EEG, percentage of peripheral arterial oxygen saturation (% SpaO2) and heart rate (HR) were recorded during wakefulness at rest (supine position) and in comfort: 1) at sea level;2) at 3600 m after 32 - 38 hours of acute acclimatization;3) at 4300 m after 145 - 153 hours of chronic acclimatization;and 4) at 4300 m immediately after a marathon race. Symptoms of AMS were evaluated with the Lake Louise questionnaire before any ECG recording. There was a significant decrease in low-voltage high-frequency activities at rest after acute hypoxic-hypobaric exposure at 3600 m as compared to sea level. After six days of acclimatization at 4300 m there was a significant increase in the power of low-voltage high-frequency activities, particularly beta and gamma, indicating an aroused waking state and an integrated activity across widely distributed cortical regions. An increase in the power of low-voltage high-frequency activities over the entire cortex was observed, particularly after completion of the marathon at 4300 m. The increase in the high-frequency activities was probably due to direct and indirect reflex activation of the forebrain and reticular activating system involved in behavioral and metabolic integration of autonomic control and arousal and due to residual activation of the somatomotor and parietal cortex after the end of the marathon. Lake Louise score always resulted lower than 3, indicating no signs of AMS in all the runners. The results of this study indicate that in well-trained and acclimatized athletes, arousal

就是圣保罗这巴西圣保罗市是世界七大城市之一，也是南美洲最大的城市；约有2200万人口居住在大都会区，1100多万人口住在郊区。1554年，耶稣会传教士发现该城，并将其命名为圣保罗（葡萄牙语为“SaintPaul”）。如今，这里的居民也多是意大利、黎巴嫩和日本的移民后代。在19世纪中期，周边的种植园开始种植咖啡作物，城市也随之迅速扩张。自此，圣保罗州首府圣保罗市开始不断发展，并逐渐成为巴西的工业及金融中心。然而，一个多世纪的蓬勃发展，却只留给这座城市（总占地面1500km^2）极少的公园、广场，甚至连步道空间都很少见。

由欧洲建筑师约瑟夫·路易-塞特和保罗·莱斯特·维纳于1948-1952年间设计的“试点方案”，是麦德林市城市规划中最重要的历史背景，该方案于1952年通过法令并开始实施。作为国际现代建设协会（CIAM）的积极参与者，塞特在麦德林市的设计中应用了国际现代建筑协会于1947年在布里奇沃特市（英国）会议上提出的现代建筑原则、概念及基准。而这些指导原则正是围绕着城市四大功能——居住、工作、游憩及交通的差异性确立的。麦德林市的城市建设提案包括：沟通水道开凿运河、沿河网建设城市、重组城市中心、建设新的行政综合体（如仍在使用中的拉·阿尔普哈拉管理中心、市郊居住区的管理）及在阿纳斯达西奥·希拉尔多特体育场周边建设体育综合设施，这是当前城市改造的一大特色。
