Veterinary Dermatology, EarlyView.Background – Recurrent urticaria is common in horses. The pathophysiology is poorly understood and treatment options are limited. Often only glucocorticoids are effective for controlling clinical signs, albeit with potential adverse effects. Studies investigating new treatments need a validated objective scoring system for the grading of skin lesions ...

乙型肝炎病毒ＢＣＰ、ＰｒｅＣ和Ｃ区基因突变与母婴传播免疫失败的相关性
Zhongshan Daxue xuebao. Yixue kexue ban, 2013 【目的】 探讨ＢＣＰ、ＰｒｅＣ和Ｃ区基因突变率及突变热点与ＨＢＶ母婴传播免疫失败的关系。【方法】 选取血清ＨＢｓＡｇ阳性且ＨＢＶ ＤＮＡ定量＞１０００Ｕ／ｍＬ的孕妇，以所分娩的新生儿是否发生免疫失败和孕妇血清ＨＢＶ ＤＮＡ定量水平将孕妇分为免疫失败组（１９例）和对照１组（免疫成功且ＨＢＶ－ＤＮＡ定量≥１．０ × １０７ Ｕ／ｍＬ，４８例）、对照２组（免疫成功且ＨＢＶ－ＤＮＡ定量＜１．０ × １０７ Ｕ／ｍＬ，３８例）。对３组孕妇血中ＨＢＶ进行ＢＣＰ／ＰｒｅＣ／Ｃ区基因ＰＣＲ扩增和测序 ...

Guangtongxin yanjiu, 2017 提出了一种基于多步插值的频偏估计算法,用于相干光通信中数字相干接收机的频偏估计补偿。该算法首先采用少量的数据点作FFT（快速傅里叶变换）,粗估计出频偏值,然后采用DFT（离散傅里叶变换）进行多步插值计算,降低了计算复杂度。在一个28GBaud的QPSK（正交相移键控）仿真系统中进行了仿真验证,结果表明,与最新报道的LS（最小二乘）算法相比,该文所提算法可以大大降低现有算法的复杂度。

New Phytologist, Volume 247, Issue 3, Page 1117-1128, August 2025.Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

非糖尿病急性冠脉综合征住院患者ＨＤＬ－Ｃ、 ＬＤＬ－Ｃ／ＨＤＬ－Ｃ水平回顾性分析
Zhongshan Daxue xuebao. Yixue kexue ban, 2015 摘 要：【目的】 回顾性分析非糖尿病急性冠脉综合征ＨＤＬ－Ｃ、ＬＤＬ－Ｃ／ＨＤＬ－Ｃ水平及冠脉病变相关性。【方法】 选择本院２０１１．０５－２０１５．０５ 住院符合急性冠脉综合征诊断标准并无２型糖尿病患者３０６例为研究对象，选择同期住院符合急性冠脉综合征诊断标准并确诊为２型糖尿病患者１７４例，以及冠脉造影正常无糖尿病患者 ２５８例为对照，所有患者均行冠状动脉造影检查。将前降支、回旋支或右冠脉中任何一支狭窄≥５０％为单支病变组；前降支、回旋支或右冠脉中任何两支病变≥５０％及左主干病变为双支病变组；将前降支、
