Acinetobacter baumannii is one of the most important human pathogens causing a variety of nosocomial infections. Carbapenem antibiotics have been primarily used to treat the A. baumannii infections. however, carbapenem resistant A. baumannii producing carbapenemases causes serious treatment problems worldwide. Outbreaks of carbapenem resistant isolates have reported in some area of the United States, but their dissemination and genetic structure of the carbapenemase encoding genes are currently little known. To understand outbreaks, dissemination, and genetic structure of the carbapenemase encoding genes in Southern Texas, 32 clinical isolates collected from Austin and houston, TX were characterized. Twenty-eight of 32 isolates were resistant to all tested β-lactam antibiotics including carbapenem (imipenem and meropenem). Three of them carried blaOXA-23 as a part of Tn2008 integrated into a known plasmid (pACICU2) and all others carried blaOXA-24 flanked by XerC/XerD-like recombinase binding sites that were adjoined by DNA sequences originated from multiple plasmids. Genotype analysis revealed that the 25 isolates carrying blaOXA-24 were all identical genotypes same as a representative isolate carrying blaOXA-24 from Chicago, IL but the 3 isolates carrying blaOXA-23 was a distinct genotype as compared with isolates carrying blaOXA-23 from Chicago, IL and Washington, D.C. Each of the blaOXA-23 and blaOXA-24 was transferred to carbapenem susceptible A. baumannii and E. coli with similar minimal inhibitory concentration (MIC) of carbapenem as that of their parental isolates but significantly lower levels of MIC in E. coli. Overall results suggest that a unique strain carrying blaOXA-23 and a similar strain carrying blaOXA-24 as seen in other geographic areas are currently disseminated in Southern Texas.

栖居于海底熔岩基底中的微生物能够侵蚀火山玻璃,形成微米级的孔洞和钻穴.这些生物改造的遗迹被矿化后,即使保存它们的火山玻璃经历了变形和改造成为变质矿物后,矿化的结构也能够保存下来.这些生物改造结构的化石记录所赋存的岩性远远超出了原位洋壳火山玻璃的范围.它们可见于蛇绿岩和前寒武纪绿岩带的变火山玻璃中.本文报道了中国五台山25.2亿年拉斑质枕状熔岩薄片中发现的丝状体型生物显微结构.而且,五台绿岩中发现的微结构在大小、形态和分布上都可以与其他产在太古宙绿片岩相枕状熔岩中的生物蚀变结构相对比.榍石LA-MC-ICP-MSU-Pb原位定年分析给出的年龄是(1.81±0.12)Ga(2σ,n=22,206Pb/238U加权平均).该年龄提供了这些生物蚀变结构矿化的最小年龄,并与区域变质事件年龄相当.这个年龄也代表这些生物蚀变时间的最小年龄估计,从而支持晚太古宙海底生物圈的存在.

Agricultural Sciences 2012年第4期3卷 501-509页

The objective of this research was to evaluate the efficacy of various pre-emergence (PRE) and post-emergence (POST) herbicides for the control of volunteer adzuki bean (Vigna angularis (Willd.) Ohwi & Ohashi) in soybean (Glycine max L.). Trials were conducted at two locations in 2005, 2006, 2007, and 2009. Experiments were arranged in a randomized complete block design with either five PRE or nine POST herbicides. Volunteer adzuki bean interference in soybean resulted in yield loss of up to 25%. Cloransulam-methyl, linuron, metribuzin, flumetsulam, and imazethapyr applied PRE provided up to 6, 24, 14, 8, and 0% control, respectively at 8 weeks after emergence (WAE), while acifluorfen, fomesafen, bentazon, thifensulfuron-methyl, cloransulam-methyl, imazethapyr, and imazethapyr plus bentazon applied POST provided 2, 2, 5, 34, 6, 4, and 12% control, respectively at 8 weeks after application (WAA). Generally, with the aforementioned herbicides, soybean yield was equivalent to the weedy control and soybean grain contamination with adzuki bean seed was consistently above the 1% maximum threshold. Chlorimuron-ethyl and glyphosate applied POST provided up to 84 and 94% visual control at 8 WAA, respectively, decreased adzuki bean density, biomass, and seed production, and generally decreased soybean contamination with adzuki bean below the 1% threshold. The only herbicides evaluated in this study that controlled volunteer adzuki bean in soybean were chlorimuron-ethyl (9 g ***-1) and glyphosate (900 g ***-1) applied POST. All the other PRE and POST herbicides evaluated did not provide adequate control of volunteer adzuki bean in soybean.

Austroeupatorium inulaefolium (B. L. robinson) K. et R. has been investigated. A collection from Ecuador gave several ent-labdanes like austrofolin and related compounds. A second collection from Paraguay gave ent-kaurene derivatives and three nor-ent-labdanes. A third investigation of material from Argentina also gave ent-kaurenes and nor-ent-labdanes, which were only slightly different from those of the Paraguay location.
