| 1. | The genes that control the body clock are most active in parts of the brain called the suprachiasmatic nuclei
控制生物钟的基因在脑部的视交叉上核的细胞内最为活跃。 |
| 2. | Brain studies suggest that there is impairment serotonin function in neurons leading to the suprachiasmatic nucleus
大脑研究表明引导视交叉上核的神经元5 -羟色胺功能有损伤。 |
| 3. | [ font = times new roman ] [ size = 4 ] the genes that control the body clock are most active in parts of the brain called the suprachiasmatic nuclei
控制生物钟的基因在脑部的视交叉上核的细胞内最为活跃。 |
| 4. | One theory is that an area of the brain , near the visual pathway , the suprachiasmatic nucleus responds to light by sending out a signal to suppress the secretion of a hormone called melatonin
一种理论认为大脑主导光线通路附近的某一区域视交叉上核受光线影响发出信号，抑制褪黑素的分泌。 |
| 5. | The other belongs in our internal clocks ( the major one of which may be physically located in a part of the brain called the suprachiasmatic nucleus ) which , left alone , would tie the body to a 25 hour ? yes , 25 ? rhythm
另一个定时系统在我们的体内时钟内（其中一个主要时钟可能位于我们大脑的称为超交叉核的那部分中）这些体内时钟在不受干扰时，会使人体有一个25小时? ?是的， 25小时? ?的生理节奏。 |
| 6. | Basis of rhythmic structure is circadian clock , which is located at suprachiasmatic nucleus ( scn ) and pineal gland in mammal . the molecular basis of which is composed of a series of genes and their corresponding protein products
生物节律的生理基础是生物钟，哺乳动物的主钟定位于丘脑视交叉上核( suprachiasmaticnucleus ， scn )和松果体；生物节律的分子基础是一系列与生物钟相关的基因及其蛋白产物。 |
| 7. | In the present study , we determine the clock and melatonin receptor subtypes ( mt 1 , mt2 ) genes in suprachiasmatic nucleus ( scn ) and lymphocytes at different time points of specific light regimes . the aim of this study is to investigate the effects of light on circadian expression of these clock related genes , and to explore possible roles and mechanisms of these genes in regulation of the diurnal rhythm
本课题采用不同的光照制，研究scn及外周淋巴细胞中的钟基因clock 、褪黑素受体基因( mt1和mt2 )的昼夜表达规律，以期了解光照对中枢和外周这三个基因昼夜节律表达的影响，并试图发现它们在生物钟昼夜节律的维持中可能的作用规律。 |
