Association between polycystic ovary syndrome and environmental endocrine disruptors: the pathogenetic mechanisms involved [PDF]
, 2016 摘要 多囊卵巢综合征(Polycysticovarysyndrome，PCOS)是一种在育龄妇女中常见的内分泌紊乱疾病，其常见特征为稀发排卵或少排卵、高雄激素血症、卵巢多囊化。PCOS的发病机制尚不明确，而许多研究表明环境因素是导致PCOS发病的重要因素。 本实验收集育龄妇女流行病学资料，并利用气象色谱-质谱联用检测了84名PCOS患者及94名对照组血清中多种环境中内分泌干扰物(endocrinedisruptingchemicals，EDCs)的含量。结合流行病调查资料和相关激素代谢物质水平 ...

Integrative Zoology, Volume 21, Issue 2, Page 218-230, March 2026.China is a global hotspot for cuckoo‐host diversity, with 17 cuckoo species, exploiting 142 host species. We reveal adaptive matching in body size and egg traits, along with niche partitioning among cuckoos, while identifying eight new host species.

Tributyltin and bisphenol A induce polycystic ovarian syndrome and its mechanisms involved [PDF]
, 2015 多囊卵巢综合征（polycysticovariansyndrome,PCOS）是以稀发排卵或无排卵、高雄激素或胰岛素抵抗、多囊卵巢为特征的内分泌紊乱的症候群，复杂且具有异质性，是婚育年龄妇女中最常见的内分泌紊乱疾病。PCOS的病因较为复杂，已有研究证明类雌激素化合物双酚A暴露（bisphenolA,BPA）与PCOS的发病有关，说明环境中的内分泌干扰物与PCOS发病存在一定的联系。 本研究以大鼠为实验动物模型，以三丁基锡（tributyltin,TBT）作为类雄激素化合物的典型代表，探究TBT（10ng/

Integrative Conservation, Volume 4, Issue 4, Page 523-526, December 2025.Here we report three cases of nesting behavior in Yunnan Province, China. Our observations confirmed the presence of multi‐individual participation during the nest guarding, and this behavior was associated with an exceptionally high clutch size. ABSTRACT Although the King Cobra (Ophiophagus hannah) has received considerable conservation attention ...

Functional Study of Ecdysone Signaling Pathway Related Genes During Ovarian Maturation and Juvenile Development of The Mud Crab, Scylla paramamosain [PDF]
, 2015 蜕皮激素在节肢动物蜕皮、附肢再生以及繁殖等生理过程起着重要作用。蜕皮激素受体（Ecdysonereceptor，EcR）在整个蜕皮激素信号通路中起重要作用。当蜕皮激素合成达到一定浓度以后，能够诱导EcR与维甲酸X受体（retinoidXreceptor，RXR）形成有功能的EcR/RXR异源二聚体，进而启动蜕皮激素信号通路产生级联反应，诱导E75、E74、BroadComplex（BR-C）等早期应答基因的转录。这些早期应答基因进一步调控下游一些蛋白酶和其它基因的陆续表达，产生次级应答 ...

Gonad development during sexual differentiation in Epinephelus akaara and E. awoara [PDF]
, 2015 赤点石斑鱼和青石斑鱼已分别被确认为双向性转变和雌性先熟的雌雄同体型种类，但是第一次性成熟前的性分化和性腺发育特征还未有深入的研究。本研究利用传统组织学切片方法，跟踪赤点石斑鱼从孵化后6周到95周和青石斑鱼从孵化后6周到85周的性腺发育过程，深入了解石斑鱼性分化过程中性腺发育特征，探讨石斑鱼性别方式的多样性。孵化后约6周的仔鱼捕获自福建漳浦附近海域，并移入当地的养殖场利用天然海水进行室外养成，直至达到商品规格(一般2年以上)。实验样品采集从2013年2月至2014年5月，每2~17周(主要5~6周)一次 ...
