U.S. mothers’ appraisals of the race‐related events of 2020: Implications for the course of maternal posttraumatic stress disorder symptoms

open access: yesJournal of Traumatic Stress, Volume 36, Issue 2, Page 272-284, April 2023., 2023
Abstract For parents of color, publicized racial violence can heighten concerns about their children's safety. The goal of this study was to test whether this form of race‐related stress exacerbates maternal posttraumatic stress disorder (PTSD) symptoms over a 4‐month period in families of color. Participants included 262 U.S.

十足目甲壳动物精子冷冻保存 [PDF]

open access: yes, 2002
【摘要】 杂交育种、种质优选、雌核发育及物种保护等研究都要涉及到精液冷冻保存。精液的长期保存 ,可以保证基因长时间的稳定性 ,能以较少的时间和空间保证精子的供应 ,没有季节限制 ,也不需较高的饲养亲本的花费 ,大大提高了选择育种的可行性。和其他水生生物大量精子冷冻研究相比 (Mistutoshi,2 0 0 0 ) ,甲壳动物精子冷冻保存研究很少 ,主要集中在十足目甲壳动物。虽然十足目甲壳动物最近在养殖上越来越重要 ,但其精子冷冻保存技术依然很少(Chow ,1985 ;Anchordogy等 ...

黄姑鱼(Nibea albiflora)伪雄鱼繁殖期精子活力分析及环境因子对其活力的影响

open access: yesHaiyang yu huzhao
伪雄鱼是由雌鱼性逆转而成的生理性雄鱼,在全雌鱼苗种的规模化繁育过程中有着至关重要的作用,但国内外对其精子活力的研究较少。为研究黄姑鱼伪雄鱼繁殖期精子活力及环境因子对其活力的影响,利用计算机辅助精子活力分析系统(CASA)对伪雄鱼的精子密度、运动率、寿命和运动速度等指标进行测定;并且设置不同的温度和pH梯度组,探究不同环境因子对伪雄鱼精子活力的影响。结果显示,伪雄鱼精子密度为(2.60~2.24)×1010个/mL;在繁殖期内,伪雄鱼精子密度呈逐渐下降的趋势,且在排精中期和晚期 ...

Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage

open access: yesRare Metals, EarlyView.
ABSTRACT Tungsten disulfide (WS2) is considered a promising anode material for sodium‐ion batteries (SIBs). However, its practical application is hindered by poor electrical conductivity, large volume changes during cycling, and sluggish ion diffusion kinetics, which lead to unsatisfactory electrochemical performance.
