简介:梦是意象的语言,在梦中,发生的是一次被动的体验,有些情绪,用伪装的形式绕过虚伪的抵抗,占据我意识的海,却又在梦之将醒时,被阳光的温度抹除。这很残忍么?也许更残忍的是梦醒后,你仿佛用另一个人生经历过的这场梦境,其中情节辗转已忘了个干净,但有些感情一半被留在梦里、一半带回给了你,不管你是否愿意面对、不论你是否因它而困惑,它依旧不为所动的扎在那里。我儿时的梦是恐惧。记得起的大多是暴乱动荡打破宁静生活的情景,在这样的梦中,我是无力的逃避者,我带着家人,用尽方法寻找着生的希望,梦醒时分,脑中充满着对灾难来临前恬静生活的眷恋不舍。我最终也不明白是什么让我总在焦虑之中,是什么让我毫无安全感。随着年龄的增长,恐惧渐渐离我而去,只是它们走的仓促,未能将恐惧中的孤独一并带走。

简介:AbstractMany factors can cause inner ear injury, such as noise exposure, chemicals, viral infection, and radiation. The main pathological manifestations of inner ear injury are local hypoxia-ischemia, micro-trauma, and an increased level of reactive oxygen species and inflammatory mediators. The contribution of the inflammatory response to the mediation of cochlear and vestibular pathologies has received increasing attention in recent years. Aseptic inflammation can devastate audition and balance, which can lead to many typical clinical inner ear diseases. In this review, we will discuss the most pertinent and recent research on inflammatory mechanisms in inner ear injury. We will also discuss the pathophysiology of some common and significant ear diseases, such as sudden sensorineural hearing loss, age-related hearing loss, noise-induced hearing loss, and Meniere’s disease.

简介:独居、群居的蝗虫许多特点地不同,例如身体颜色,morphometrics和行为。关于行为,当群居的动物寻求对方时,独居的动物躲避对方“s同伴,因此他们的拥挤的行为。一般活动,取决于温度,在整个日子发生,但是在独居的蝗虫是低得多的。当群居的蝗虫在白天期间定期飞时,独居的蝗虫偶尔到夜里飞(聚集)。寻找新试金到识别控制或修改方面的物质(阶段)行为,我们设计了简单活动试金,想补充存在行为的测量工具。一般活动在墙点击的数字被反映,也就是说在蝗虫和一个小竞技场的垂直的墙之间的接触的数字。用这个单个参数,我们能确定在美女的全部的活动和成年人的差别饲养隔离(独居),重新聚集尾部、饲养人群(群居)在不同条件下面的蝗虫。而且,我们证明在在三不同adipokinetic荷尔蒙的注射以后的5thinstar美女的活动有分裂期间和intra阶段依赖者差别。
