近年来鄱阳湖的微塑料环境污染日益受到关注.选取鄱阳湖白沙湖为研究区,采集白沙湖水体和沉积物以及其中的微塑料样品,通过傅里叶红外光谱确定微塑料的聚合物类型为聚乙烯(PE)、聚酯纤维(PET)、聚丙烯(PP)和聚苯乙烯(PS).并利用16S高通量测序技术分析水体、沉积物中和微塑料表面细菌群落结构组成.微塑料表面细菌的物种丰富度与多样性均低于周围水体和沉积物.NMDS分析结果表明,微塑料表面与周围沉积物、水体中的细菌群落结构差异较大.水体和沉积物中的细菌群落组成与微塑料表面存在差异,门水平上沉积物与沉积物中微塑料表面优势菌门为变形菌门(Proteobacteria)和拟杆菌门(Bacteroidota),其在微塑料表面相对丰度高于沉积物;水体中微塑料表面变形菌门相对丰度高于水体,而拟杆菌门、放线菌门(Actinobacteriota)的相对丰度明显低于水体.属水平上马赛菌属(Massilia)和假单胞菌属(Pseudomonas)是微塑料表面的优势菌属,相对丰度明显高于周围水体和沉积物.通过BugBase表型预测发现微塑料细菌群落可移动基因元件含量、生物膜形成、潜在致病性及胁迫耐受等表型相对丰度明显高于周围水体和沉积物.结果发现微塑料可能会促使致病菌在内的有害菌的传播,提高细菌群落的潜在致病性,且微塑料表面细菌群落具有更高的可移动基因元件含量表型.通过揭示微塑料污染对微观层面湿地生态的潜在危害,可为维护湿地生态稳定性提供科学参考.

Vascular tissues are very important for providing both mechanical strength and long-distance transport. The molecular mechanisms of regulation of vascular tissue develop- ment are still not fully understood. In this study we identified ANACoo5 as a membrane-associated NAC family transcription factor that regulates vascular tissue development. Reporter gene assays showed that ANACoo5 was expressed mainly in the vascular tissues, increased expression of ANACoo5 protein in transgenic Arabidopsis caused dwarf phenotype, reduced xylem differentiation, decreased lignin content, repression of a lignin biosynthetic gene and genes related to cambium and primary wall, but activation of genes related to the secondary wall. Expression of a dominant repressor fusion of ANACoo5 had overall the opposite effects on vascular tissue differ- entiation and lignin synthetic gene expression. The ANACoo5- GFP fusion protein was localized at the plasma membrane, whereas deletion of the last 20 amino acids, which are mostly basic, caused its nuclear localization. These results indicate that ANACoo5 is a cell membrane-associated transcription factor that inhibits xylem tissue development in Arabidopsis.

随着全球人口老龄化,脑衰老(brain aging)成为一个日益突出的问题。脑衰老涉及神经元数量减少、突触连接减弱和脑区功能改变,导致记忆力下降和认知功能受损等症状。本综述详细回顾了运动通过改善大脑可塑性延缓脑衰老的研究进展。运动通过影响突触可塑性相关蛋白质和神经递质、调控脑源性神经营养因子表达、逆转神经细胞减少和改善线粒体功能,对脑衰老产生积极影响。然而,未来的研究需要关注不同运动类型和强度对脑衰老的影响,以及运动与其他干预措施的协同作用。本综述将有助于理解运动延缓脑衰老的机制并对制定相关预防和干预策略至关重要。

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in june 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in june 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

目的:评价使用多西环素和生理盐水处理脱位恒牙对牙髓及牙周愈合的影响。方法:将38例患者(男22例,女16例,年龄7~14岁)的44颗脱位恒牙随机分为2组。在复位植入牙槽窝前,A组21颗牙使用0.05 mg/mL多西环素溶液浸泡5 min,B组23颗牙使用生理盐水浸泡5 min。术后定期随访并观察牙根发育情况,使用Mann-Whitney U检验评价2组愈合情况的差异。结果:2组脱位牙之间的基本特征无显著差异。A组18颗牙被诊断为牙髓坏死,3颗牙有炎症性吸收,13颗牙有骨性黏连,6颗被拔除。B组16颗牙被诊断为牙髓坏死,4颗牙有炎症性吸收,12颗牙有骨性黏连,7颗被拔除。2组间的主要临床随访结局差异无统计学意义。结论:与生理盐水相比,使用多西环素溶液处理脱位恒牙并未显示出明显的优势。
