Disentangling complex relationships and disjunctions in western Camassia: Integrating multiple criteria to resolve taxonomic boundaries

open access: yesAmerican Journal of Botany, Volume 112, Issue 12, December 2025.
Abstract Premise Understanding genetic and morphological variability helps efforts to sustain landscapes and develop effective species concepts for resolving difficult groups. To unravel puzzling relationships and range disjunctions, we applied morphometrics, phenology, phylogenetics and population genetics in Camassia species with cultural, ecological,

骨科老年手术患者术后金黄色葡萄球菌感染危险因素的Logistic回归分析

open access: yesZhongguo shiyan zhenduanxue, 2015
随着现代交通业、运输业的蓬勃发展,骨伤、骨疾病导致的骨科手术患者不断增加,由骨科手术引起的术后感染也随之不断增加。骨科手术患者术后感染部位以切口感染、皮肤软组织感染和泌尿系统感染最为常见[1],术中无菌操作技术不良、侵入性操作、滥用抗菌药物、患者机体抵抗力较低、切口愈合不良、手术时间较长、手术部位在腰腹以下等因素均可提升骨科手术患者术后感染的发生风险,特别是老年患者更是骨科术后感染的高发人群[2 ...

High‐frequency sampling unveils biotic and abiotic drivers of rapid phytoplankton morphological changes

open access: yesNew Phytologist, Volume 248, Issue 5, Page 2528-2541, December 2025.
Summary Phytoplankton, as primary producers, play a key role in aquatic ecosystems. Their community turnover is shaped by morphological traits that enable adaptation to diverse abiotic and biotic factors. Yet, the temporal scale of these dynamics remains poorly understood due to limited high‐frequency sampling studies.

骨科患者医院感染临床病原学检测分析

open access: yesZhongguo shiyan zhenduanxue, 2013
骨科患者多采取手术疗法,其手术时间相对较长,术中多伴有辅助检查,且骨科患者由于失血、制动、住院时间长及病原微生物易在骨髓腔、骨松质中藏匿停留、生长、繁殖等原因,极易发生感染。软组织、骨与关节一旦发生感染,轻则延长疗程,增加医疗费用,重则并发肢体关节的严重功能障碍[1]。为了解我院骨科患者发生感染的病原菌及耐药状况,为骨科控制感染与临床治疗提供参考依据,我们对骨科发生医院感染患者的108份标本进行细菌培养和药敏试验结果进行分析,现报告如下。
