Chris Hammond, at King's College,[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ *5`4 $w7``E\^?AC?FroG] The variations in DNA amount to misspellings in the genetic code. These alter the activity of three genes that control the growth of the eyeball and ensure light entering the eye is converted into electrical pulses in the retina.[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ fqC=|MfQbSMPr =FqUFroG] The discovery helps scientists piece together how a healthy eye becomes short-sighted and points the way to medicines to prevent it in children.[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ Q]Orr/ZmL_2O€;E"UFroG] "My hope is that we can identify a pathway that we can block with eyedrops or tablets that will stop the eye growing too much and without interfering with normal brain development or other processes in the body,"[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ 8uMF=ns0!B OGkFroG] ¿Æѧ¼Ò×î½ü·¢ÏÖÁËÒ»×éÓë½üÊÓÓйصÄÒÅ´«ÃÜÂë¡£½üÊÓÊÇÄ¿Ç°ÊÀ½çÉÏ×î³£¼ûµÄÑÛ²¿¼²»¼¡£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ ,'/%4rJD€0X ]FroG] ÕâÏî·¢ÏÖÓÐÖúÓÚ²ûÃ÷½üÊӵijÉÒò£¬²¢ÎªÑз¢Ô¤·À½üÊÓµÄÒ©Îï´øÀ´ÁËÏ£Íû¡£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ ^&J' P(8|.C !WFroG] ÕÒµ½½üÊÓµÄÉúÎïÆðÒò¿ÉÒÔ°ïÖúÑо¿ÈËÔ±ÑÐÖƳö·ÀÖ¹¶ùͯÊÓÁ¦ËæÄêÁäÔö³¤²»¶ÏÏ»¬µÄÑÛÒ©Ë®»òÒ©¼Á¡£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ l6N= #A\]8MrZ7FroG] ½üÊÓÍùÍùÐγÉÓÚÇàÉÙÄêʱÆÚ¡£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ iAdlv =`[seX:7 9FroG] ¶Ô²»Í¬µÄ½üÊÓ»¼ÕßÀ´Ëµ£¬»ùÒòµÄÖ²¡ÒòËØËùÕ¼±ÈÀý²»Í¬£¬µ«¶ÔÓÚÊÓÁ¦¼«²îµÄȺÌå¶øÑÔ£¬´óÔ¼80%µÄ²¡Àý¶¼ÊÇ»ùÒòµ¼Öµġ£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ b0t/tWO[V&,vgzFroG] ·¢±íÔÚ¡¶×ÔÈ»-ÒÅ´«Ñ§¡·ÆÚ¿¯ÉϵÄÁ½Ïî¶ÀÁ¢Ñо¿¶¼·¢ÏÖÁ˸ü³£¼ûÓÚ½üÊÓ»¼ÕßµÄDNA¸Ä±ä¡£Â׶شóѧ¹úÍõѧԺµÄ¿ËÀï˹•¹þÃɵ·¢ÏÖ£¬15ºÅȾɫÌåÉϵÄÒ»¸öDNAƬ¶Î¸ü³£¼ûÓÚ½üÊÓ»¼Õß¡£Â¹Ìص¤ÒÁÀ˹Īµ¤Ò½Ñ§ÖÐÐĵĿ¨ÂÞÁÕ•¿ËÀ¸¥·¢ÏÖ£¬15ºÅȾɫÌåÉϵÄÁíÒ»¶ÎDNAÓë½üÊÓÓйء£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ JwZ?6}+dJF_$yKoFroG] DNA±ä»¯Ï൱ÓÚ¡°Æ´´í¡±ÁËÒÅ´«ÃÜÂ룬¸Ä±äÁËÈýÖÖ»ùÒòµÄ»î¶¯¡£ÕâÈýÖÖ»ùÒò¿ØÖÆÑÛÇòÉú³¤¡¢È·±£ÑÛ²¿Ëù¼û¹âÏßÔÚÊÓÍøĤת»¯ÎªµçÂö³å¡£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ FK3lI :jK.nd.'O\FroG] ÕâÏî·¢ÏÖ°ïÖú¿Æѧ¼ÒÍêÕûÀí½âÁ˽¡¿µµÄÑÛ¾¦ÈçºÎ»¼ÉϽüÊÓ£¬²¢ÎªÑÐÖƶùͯʱÆÚÔ¤·À½üÊÓµÄÒ©ÎïÖ¸Ã÷ÁË·½Ïò¡£[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ ~3YOe8q e~r1lyLY6NFroG] ¹þÃɵÂÔÚ½ÓÊÜ¡¶ÎÀ±¨¡·²É·Ãʱ˵£º¡°ÎÒÏ£ÍûÎÒÃÇ¿ÉÒÔÕÒµ½Ô¤·À½üÊÓµÄÑÛÒ©Ë®»òÒ©¼Á£¬·ÀÖ¹ÑÛ²¿·¢Óý¹ý¿ì£¬Í¬Ê±²»´òÂÒÕý³£µÄÄÔ²¿·¢Óý»òÆäËüÉíÌå»î¶¯¡£¡±[ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ Oeso"AtWr,Q?cteaFroG] [ÎÄÕ°æȨ ½ûֹתÔØ:¿¼ÊÔÓëÆÀ¼Û http://www.trgroup.com.cn/te/ W14k9Mh;€pz #qYfFroG] |
