| 1 | 继发性弥漫性细支气管病显示文摘2006年8月,一名57岁女性来到作者所在医院急诊科就诊。症见:干咳、气短、疲乏。症状已持续6周,且期间咳嗽逐渐频繁。患者无发热,不吸烟,也未接触任何可引起咳嗽的刺激物,无过敏史。既往患有胃食管反流病和抑郁症,分别采取口服泮托拉唑和文拉法辛进行治疗。然而,患者未坚持定期服药,原因是“厌恶”药物。 | Nishith K Singh Dharmesh Mehta Peter White 程岗(译) | 2008 | 世界临床医学2008，2，5： | 0 |
| 2 | Metagenetics of fairy rings reveals complex and variable soil fungal communities显示文摘Although fairy rings are widely observed,little is known about the community processes associated with them.Here,we studied fairy rings in a natural grassland in northern Mongolia by sampling soils outside(future stage),directly under(present stage),and within(past stage)the rings,to represent different time stages during the expansion of fairy rings.Soil DNA was extracted for amplicon sequencing of the fungal ITS1 region.The present stage had reduced fungal diversity and different fungal communities toward the other stages.Most strikingly,there was an increase in the pathogenic fungus Gibberella baccata in the present stage of most rings and the saprotrophic fairy ring fungus Lepista luscina in several.However,no mushrooms of Lepista had been recorded from any of these rings during several years of observation.Known fairy ring fungi were not found in the present stage of every ring,even in some known rings to have previously displayed mushrooms of such species.It is possible that these fungi occurred or were more abundant at the unsampled leading edge of the ring.The increase in G.baccata is intriguing,but its importance,if any,is unclear.It is also unclear whether consortia of fungi or other microbes might be present in these rings.The absence or low abundance of the previously reported fairy ring fungal species suggests that their presence is transient,with rapid replacement by other fungi.No differences in soil parameters were found between the fairy ring stages,except for aluminum.There is a need for broader sampling,including analysis of non-fungal biota,to understand the functional diversity of fairy ring fungi and the consequences for plant communities. | Siyu XU Ke DONG Sangseob LEE Matthew Chidozie OGWU Sainbileg UNDRAKHBOLD Dharmesh SINGH Dagvatseren ARIUNZAYA Orsoo ENKHMANDAL Laura A.SPENCE Anarmaa SHARKHUU Brenda B.CASPER Jonathan M.ADAMS Bazartseren BOLDGIV | 2023 | Pedosphere2023，33，4： | 0 |
