High-spin levels of ^189Pt have been studied with the in-beam T-spectroscopy method via the ^176Yb（^18O,5n） reaction at the beam energies of 88 and 95 meV. The previously known ＂vi-1 13/2 band has been confirmed, and its unfavored signature branch extended up to the 31/2^＋ state. Within the framework of the triaxial particle-rotor model, the vi-1 13/2 band is suggested to be associated with the 11/2[615] configuration, and to have triaxial deformation.

偏头痛发作中无症状的左心室功能不全

世界核心医学期刊文摘（神经病学分册） 2006年第9期2卷 45-46页

Objective. -The aim of the present study was to evaluate cardiac performance of patients with migraine attacks during the overload produced by phenylephrine infusion. Background. -It is known that circulatory changes occur during migraine. However, the relationship between this finding and transient cardiac dysfunction is still unknown. methods. -By means of two-dimensional direct m-mode echocardiography, we measured fractional shortening, ejection fraction, and mean velocity of circumferential fibers shortening in 18 patients with migraine and in 10 normal subjects as a control group. These measures were performed in two different periods: during attack-free intervals and during attacks. Pain intensity of typical migraine attack was evaluated on a 0 to 10 scale. Results. -Cardiac size and function were normal at rest in both groups. However, during migraine attacks, phenylephrine infusion provoked significant decrease in fractional shortening,EF, and mean velocity of circumferential fibers shortening, followed by concomitant increase of headache severity. On the other hand, during the attack-free interval and in the control group phenylephrine infusion did not show significant changes in cardiac function parameters. Conclusions. -Our data suggest that left ventricular dysfunction during the phenylephrine test could participate in the complex pathophysiological mechanism of migraine attacks.

Wild rodents were collected using live snap traps in pistachio gardens of Kerman Province, Southeast Iran from 2007 to 2009, then some physiological parameters of them were measured. The samples were identified as follow: nesokia indica, meriones persicus, meriones lybicus and Tatera indica. Blood samples were obtained from the heart, then the blood parameters (glucose, cholesterol, triglyceride, total protein, HDL, red and white blood cell number) in wild species of rodents and laboratory rat were compared. The results showed that there were no significant differences in serum glucose, triglyceride, HDL and total protein levels among different experimental groups. The concentration of cholesterol in T. indica was more than that in n. indica (P numbers of red blood cells also showed significant difference between wild garden rodent species and laboratory rat (P numbers of white blood cells showed no significant difference.

作为广泛宣传的“开放政策”的一部分,中国建立了几个经济特区,并在1984年宣布了14个沿海城市为“开放城市”。建立这些经济特区的原因主要在于吸收先进的生产技术和现代管理技术,然而在香港投资者眼里,主要的吸引力在于充足和廉价的劳力,以及作为发展中国家中国的特惠关税。这些经济特区也可能被设想作为一个过濾器,使资产阶级成份不易侵入中国其他地方。深圳在几个经济特区中是最成功的一个,首要的原因在于它毗邻香港。当然,它的成功也可归于香港的大多数商业团体是由有中国南方的语言和风俗的中国人经营的。这个因素显然促进了商业活动的进行,而且当谈到在深圳的香港投资时,“外

The photodegradation of irradiated thin films of poly (para-methylstyrene) with 265 nm radiations in the presence of airand as a function of irradiation time has been studied using UV-VIS, fluorescence and FT-IR Spectroscopic techniques. The influence of phthalate and terephthalate plasticizers on stability of poly (para-methylstyrene) towards irradiations was also investigated. Blending with phthalate plasticizers was found to cause a higher efficiency of photodegradation than that obtained in doping with terephthalate plasticizers. The intensity of absorption was also found to increase with time of irradiation and in change in the shape of the spectra at longer wavelength, thus indicating a possibility of photodegradation of polymer chains. The analysis of the FT-IR spectra of the irradiated and non-irradiated samples, shows a predominant absorption associated with carbonyl compounds with 1740 cm-1. In addition, the observed increase in the intensities of the carbonyl and hydroxyl regions of the FT-IR spectra, have provided an evidence for the photodegradation as well as photo-oxidation of polymeric chains. The presence of the plasticizer in the polymer backbone was found to accelerate the photodegradation of polymeric chains.
