粘液瘤

Methods:The magnetic resonancestudies were performed in the 14 patients with non myxomatous cardiac and pericardial tumors with the spin echo and cine pulse sequence.

收集经手术病理证实的原发性非粘液瘤性心脏心包肿瘤 14例，行 MRI自旋回波多体位扫描及磁共振电影检查。

Expression analyses identified increased expression of numerous TGF-beta-related genes that regulate cell proliferation and survival and plausibly contribute to myxomatous valve disease.

他们注意到，多数效应器分子的表达增加降低了TGF-β的信号作用，包括可诱导TGF-β的H3基因、内皮素-1、组织抑制因子金属蛋白酶1、致骨形态学发生的蛋白和&调节细胞增生和存活可能还有促进粘液瘤性疾病的基因&。

On sonography, myxomas are soft fluctuant hypoechoic masses, which are encapsulated and usually contain cysts Fig.

超声显示粘液瘤是质软有波动的低回声肿物，有包膜，内部为囊性（Fig17）。

Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features.

蛋白激酶A调节亚基因PRKAR1A的变化引起蛋白激酶A系统失调，导致了遗传性卡尼复合肿瘤综合症，其中包括了心脏粘液瘤作为它的一个主要特征。

BACKGROUND: Protein kinase A signaling has long been known to play an important role in cardiac function. Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features.

背景：长期以来，蛋白激酶A信号途径被认为在心功能中起着重要作用，蛋白激酶A调节亚单位基因PRKAR1A的突变导致蛋白激酶A系统失调，引起遗传性肿瘤综合征－Carney合成，其中心脏粘液瘤作为其主要特征。

Background— Protein kinase A signaling has long been known to play an important role in cardiac function. Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features. Mouse models of this genetic defect have been unsatisfactory because homozygote null animals die early in development and heterozygotes do not exhibit a cardiac phenotype.

背景——蛋白激酶A信号传导在心功能中发挥了重要作用早已为人们所知蛋白激酶A调节亚基因PRKAR1A的变化引起蛋白激酶A系统失调，导致了遗传性卡尼复合肿瘤综合症，其中包括的心脏粘液瘤作为它的一个主要特征此种遗传缺陷的小鼠模式仍然不能令人满意，因其纯合体空白动物在发展中早期死亡，而杂合体不能显示心脏表型

Myxomas are easily diagnosed by echocardiography.

超声心动图可容易诊断粘液瘤。

Most myxomas occur in the intramuscular compartment

大部分粘液瘤发生在大腿，上臂，小腿臀部的肌肉内间隔。

The decrease in distribution and numbers of some species of native birds in New Zealand - the bell bird for example - has been attributed to disease rather than predation,所以答案为D.

根据短文得知，试图把多发粘液瘤病引进到新西兰以控制野兔的数量，这一计划失败了，主要是因为在该国没有昆虫传播这种病。

This rabbit had no natural enemies in the Antipodes, so that it multiplied with that promiscuous abandon characteristic of rabbits.

科学家们发现，这种特殊品种的兔子易患一种叫&多发性粘液瘤&的致命毒性疾病。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
