查询词典 deafness

BACKGROUND: There is a need for more effective therapeutic methods associated with less side effects for the treatment of inner ear diseases such as idiopathic sudden deafness. Intratympanic steroid injection cause local infiltration and lower systemic side effect, however, the efficacy of treatment was not available.

背景：传统上以类固醇治疗突发性耳聋的投予方式不外乎口服、肌肉或静脉注射，但皆有发生全身性副作用的危险性存在；鼓室内注射类固醇只造成局部的吸收，可降低全身性副作用，但其是否有效则尚待研究。

Objective To explore audiological features of matrilineal non-syndromic deafness and its molecular mechanism.

目的 探讨母系遗传性非综合征性耳聋的听力学特征及分子遗传学机制。

45 positive loci obtained from this family may be as the candidate positions for matrilineal non-syndromic deafness .

本文经全基因组扫描所确定的45个阳性位点可作为本家系连锁分析的候选位点。

Objective To investigate the changes of subjective auditory threshold and T-level after cochlear implantation in prelingual deafness children.

目的 调查语前聋儿童人工耳蜗植入术后声场主观测听阈值和对应T值的变化趋势。

Approximately 1 in 1000 children is affected by deafness at birth or before 2 years of age, i.e., in the prelingual period.

大约有千分之一婴儿在出生时或在小孩早期罹患重度听障，有50 %的学习语言前感音神经性听障是因为Cx26基因突变所造成。

Therefore, base on our findings, we have developed a simple molecular test for the 235deC, 299-300delAT and 551G to A mutations and it should be considerable help to those families in understanding the cause of their children having the prelingual deafness.

这些结果可以对於已知遗传成因的学习语言前期非症候群听障家属提供遗传谘询。

We have sequenced the coding region of Cx26 gene from 190 Taiwanese patients with prelingual deafness and 120 unrelated normal individuals. In the deaf patients, three mutations were found: missense mutation, 551G to A and deletion, 235delC and 299-300delAT.

收集120位听力正常人及190位听障孩童对Cx26基因进行多型性比对发现有5种多型性，其中有4种多型性是之前已被发表的：79G→A(V27I)、109G→A(V37I)、341A→G(E114G)及608T→C(I203T)，另发现有一个新的多型性(558G→A)。

Perhaps the most common cause of nerve deafness is presbycusis.

也许神经性耳聋最常见的原因是青年性耳聋。

Perhaps the most common cause of nerve deafness is presbycusis.

也许神经性耳聋最常见的原因是老年性耳聋。

But while more than 100 genes are known to play a role in congenital deafness, scientists have yet to pinpoint any gene in humans that plays a role in presbycusis, or age-related hearing loss.

但是已知道有100多个基因对先天耳聋有作用，科学家还没有精确指出到底是什么基因在老年失聪中起作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
