目的：探讨血清超敏 c 反应蛋白与老年人缺血性脑卒中的相关性。方法选择急性脑梗死患者120例为脑梗死组，选择同期体检的健康老年人100例为对照组。对两组血清中的超敏 c 反应蛋白水平进行检测，对不同脑梗死面积、不同神经功能缺损评分患者的血清超敏 c 反应蛋白水平进行分析。结果脑梗死组血清超敏 c 反应蛋白水平为（10．17±3．13）mg／L，显著高于对照组[（0．81±0．24）mg／L]，差异有统计学意义（t ＝29．82，P ＜0．05）；随着脑梗死患者梗死灶容积的增大和神经功能缺损评分的增加，患者血清超敏 c反应蛋白的水平逐渐升高（P ＝0．01）。结论老年缺血性脑卒中患者血清中超敏 c 反应蛋白水平高于健康人，且梗死灶容积越大、神经功能缺损越严重，血清超敏 c 反应蛋白水平越高，对于缺血性脑卒中的早期诊断有一定的借鉴意义。

candida albicans is one of the most common fungal pathogens, and causes systemic and invasive infections in humans. c. albicans biofilms are composed of yeast and hyphal and pseudohyphal elements, and the transition of yeast to the hyphal stage could be a virulence factor. In this study, diverse essential oils were initially investigated for anti-biofilm activity against c. albicans strains, and cascarilla bark oil and helichrysum oil and their components -longipinene (a major constituent of both) and linalool were found to markedly inhibit biofilm formation without affecting planktoniccell growth. Moreover, -longipinene and linalool were found to synergistically reduce biofilm formation. Notably, treatments with cascarilla bark oil, helichrysum oil, -longipinene, or linalool clearly inhibited hyphal formation, and this appeared to be largely responsible for their anti-biofilm effect. Furthermore, the two essential oils, -longipinene and linalool, reduced c. albicans virulence in caenorhabditis elegans.

This paper deals with multiobjective programming problems with support functions under （G, c, ρ）-convexity assumptions. Not only sufficient but also necessary optimality conditions for this kind of multiobjective programming problems are established from a viewpoint of （G, c, ρ）-convexity. When the sufficient conditions are utilized, the corresponding duality theorems are derived for general Mond-Weir type dual program.

calotropis procera and calotropis gigantea are medicinal plant having therapeutic value. The leaf extracts of c. procera have been investigated, its pharmacological actions in detail and leaf extracts of c. gigantea were not studied till date. The objective of present work was to find the bioactive constituents present in the ethanolic leaf extract of c. procera and c. gigantea to evaluate their antibacterial and anifungal activities. The major phytochemical groups in c. procera ethanolic leaf extracts were fatty acid ethyl ester (21.36%), palmitic acid ester (10.24%), linoleic acid (7.43%) and amino acid (8.10%) respectively, whereas ethanolic leaf extracts of c. gigantea contain palmitic acid (46.01%), diterpene (26.53%), triterpene (17.39%), linoleic acid (5.13%) as the major phytochemical groups. Ethanol extract of c. procera leaves showed the highest inhibition (11mm) against Escherichia coli, while ethanolic extract of c. gigantea leaves inhibited Klebsiella (20mm). These findings will use in new directions in pharmacological investigations. [GRAPHIcS] .

One of the most distinctive colour polymorphisms of any mammal occurs in black bears (Ursus americanus kermodei Hornaday) of the Great Bear Rainforest of coastal British columbia. We use carbon and nitrogen stable isotope values and c/N ratios along segments of hair shafts obtained from 14 white and 12 black individual bears to quantify dietary niche of the morphs as a test of the multi-niche model for a polymorphism. On Gribbell Island, where the white bear reaches 30%, N-15 is significantly (GLM repeated measures) more enriched (more marine-derived nitrogen) in the white morph than in the black morph in each season (spring, summer, autumn). On the adjacent Princess Royal Island, where the white morph is less common, both morphs are highly enriched during autumn (delta N-15 = +11aEuro degrees), but there are no isotopic differences between morphs in any season. On both islands, c/N ratios (3.1) of the black morph decrease from spring to autumn, converging on the lower average values for the white morph. Our data suggest that niche of the white morph involves increased use of a marine-associated diet and that ecological segregation between the morphs has facilitated the historical persistence of the polymorphism.
