Haiyang yu huzhao全氟辛酸(perfluorooctanic acid, PFOA)是一种具有多系统毒性的新污染物，对双壳贝类可产生一定的免疫毒性效应，损害机体的正常免疫功能。益生菌作为一种安全无毒的食品级制剂，已被应用于水产养殖行业，用以提高水生生物的免疫防御能力。然而，益生菌对贝类中新污染物所引发的生物毒性是否有消减作用，目前尚不可知。据前期研究，新污染物PFOA在水生生物尤其贝类中存在较高的蓄积量，具有潜在的生态和健康风险。因此，探索经济贝类中益生菌对PFOA免疫毒性的消减作用具有重要意义 ...

肺感颗粒联合西医常规治疗改善流行性感冒患者短期临床症状的前瞻性观察研究
浙江大学学报. 医学版目的：评估中药制剂肺感颗粒联合西医常规治疗改善流行性感冒（简称流感）患者短期症状的临床疗效。方法：采用前瞻性观察研究设计，纳入2024年2月至3月在浙江大学医学院附属第一医院发热门诊就诊的流感患者。按照是否使用肺感颗粒分为观察组（肺感颗粒联合西医常规治疗）和对照组（西医常规治疗）。采用中医症状评分量表，分别于患者就诊第1天和接受治疗后的第3天评估患者发热、咳嗽、咽痛等主要症状，以及胸闷、食少、肌肉酸痛、口干等次要症状。通过配对秩和检验比较不同组别治疗前后中医症状量表评分的改善程度 ...

Zhejiang Daxue xuebao. Lixue ban, 2014 以杭州市7条主要河道21个监测断面1循环年的水质监测数据为依据，运用污染指数法和模糊评价法对市区主要河道水质进行综合评价，同时探讨2种水质评价方法的评价效果.结果表明：①杭州市区主要河道均存在不同程度的污染，主要污染物是TN、-N和TP，即氮磷营养盐，而有机污染相对较小；②污染指数法评价结果与实际水体的标准差距较小，与真实情况吻合较好；③当水质为劣V类时，模糊评价结论偏保守，而当某项指标严重超标时则易使评价结果偏重；④污染指数法更适合杭州市区河道水环境的评价.

Wildlife Letters, EarlyView.We examined changes in perceived risks associated with chronic wasting disease (CWD) and perceived trust in wildlife agencies over time across 10 studies in eight states. Results indicated that perceived risks to both deer and humans declined the longer the disease had been in a state. Results also indicated that agency trust evaluations were positive,

Conservation Biology, EarlyView.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Conservation Biology, EarlyView.Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.
