Distinct Biotypes of Visual Perception in Major Depressive Disorder

open access: yesAdvanced Science, EarlyView.
In a discover dataset (272 acute MDD patients), this work identifies a novel depression biotype characterized by impaired visual motion perception, using machine learning clustering. An independent dataset confirms the robustness of this biotype through cross‐validation and demonstrates its generalizability.

投喂频率对横带髭鲷(Hapalogenys mucronatus)幼鱼生长、体成分、消化系统酶活及组织结构的影响

open access: yesHaiyang yu huzhao
为探究投喂频率对横带髭鲷幼鱼生长性能、营养成分、消化酶活性及消化系统形态结构的影响,选用初始体重为(7.13±0.93) g的活力较好幼鱼,随机分为4组,每组3个重复,每个重复20尾鱼。4个实验组的投喂频率分别是1次/d (F1)、2次/d (F2)、3次/d (F3)、4次/d (F4),试验持续8周。结果表明,随着投喂频率增加,终末体重、增重率、特定生长率、摄食率均有所上升,但F3和F4组没有显著差异,F4组较F1组终末体重增加了8.29 g、增重率提高了63%、摄食率提高了20 ...

Determination of eight volatile benzene series compounds in soil or sediment by headspace-gas chromatography(顶空气相色谱法测定土壤或底泥中的八种苯系物)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2013
为快速、准确监测环境土壤或底泥中苯系物的含量,建立了一种顶空气相色谱法同时测定土壤或底泥中8种苯系物的方法.采用Nukol毛细管气相色谱柱实现了各组分的良好分离,优化了色谱条件,顶空进样条件.在优化条件下,8种苯系物在13 min内能实现完全分离,在10~500 µg • kg-1浓度范围内组分含量与峰面积呈线性相关,相关系数为0.990 6~0.995 7,检出限为2 µg • kg-1,回收率为94%~114%,相对标准偏差为2.4%~5.2%(n =3).结果表明,建立的顶空气相色谱法简单快速 ...

浙江省野生动植物进出口现状及管理对策

open access: yes野生动物学报, 2004
浙江省野生动植物资源丰富,对外贸易活跃。据统计,2003年浙江省野生动植物及其产品贸易额达24.5亿元,比前两年有大幅增加(2001年为19亿元,2002年为21.5亿元),这充分说明野生动植物对外贸易已日益成为浙江省经济发展的一大新亮点。研究分析野生动植物进出口中的基本情况、及时发现新问题、制定新对策,已成为当前进一步规范野生动植物进出口管理的重要课题。
