On the basis of the avidity of lesional macrophages for polysaccharide-containing supramolecular structures such as nanoparticles, we have developed a new positron emission tomography agent with optimized pharmacokinetics to allow in vivo imaging at tracer concentrations.

基于病变巨噬细胞和含多糖的超分子结构，如纳米颗粒的亲和性，我门研发出一种新的PET显像剂，该显像剂具有最优化的药代动力学，在示踪浓度时可在体显像。

①Location of WD gene in Ch inese: Using pairwise linkage analysis and multipoint linkage analysis method, w e constructed a genetic map of DNA markers within D13q14.2-3 which refined the location of WD gene by restriction fragment length polymorphism and microsatellite polymorphism analysis;②Screen for mutations of WD gene in Chinese people: we detected the structure of 21 exons of WD ge ne in 45 patients from 39 pedigrees by PCR-SSCP(Single strand conformation poly morphism) and PCR-DNA sequencing technology, found a new mutation in exon 5 and nuclcotide sequence analysis showed it is a T insertion. We also conformed the Arg778Leu in exon 8, the highest frequence mutation point in Chinese people, wit h mutation rate 22.8%in total;③Carrier detection and presymptomatic diagnosi s of WD: Based on DNA recombination technology, we peformed successfully the gen e diagnosis in all individuals of 79 families with WD and built up a helpful spe cific enzyme cut method (PCR-Msp1) to detect the carrier and presympomatic patients in Chinese pe ople with WD.

①WD的基因定位研究：通过RFLP及微卫星多态性分析，应用两位点及多位点连锁软件，建立了中国人WD基因在D13q14.2-3区域的精细遗传连锁图谱，从而首次对中国人WD基因进行了精确定位；②WD基因突变研究：应用PCR-SSCP及DNA测序技术，对39个家系45名WD患者进行该致病基因的21个外显子突变筛选，发现WD基因5号外显子存在新的T插入突变，并证实中国人WD基因的突变热点为8号外显子，突变形式为Arg778Leu，其频率为22.8%；③WD的症状前诊断和杂合子检出：应用DNA重组技术对79个家系进行基因诊断，成功地进行了WD的症状前诊断和杂合子检出，并建立了WD的基因筛选的PCR-Msp 1酶切方法。

Color may also be modified by traces of iron and other metal salts and organic substances, for example cyanin is red in roses but blue in the cornflower.

此外一些微量的离子，金属盐以及其他的有机物质也可以改变其显色，例如花青素在玫瑰中显红色而在玉米花中显蓝色。

The gonadotropin releasing hormone receptor gene was studied as a candidate gene for the prolificacy of Small Tail Han sheep. Eight pairs of primers were designed to detect single nucleotide polymorphisms of exon 1, exon 2 and exon 3 of GnRHR gene in both high fecundity breeds and low fecundity breeds (South African Mutton Merino, Corriedale and Chinese Merino sheep) by PCR-SSCP. Only the products amplified by primers P4 and P7 displayed polymorphisms.

设计8对引物，应用聚合酶链式反应-单链构象多态性技术检测促性腺激素释放激素受体（gonadotropin releasing hormone receptor， GnRHR）基因外显子1、外显子2和外显子3在高繁殖力品种和低繁殖力品种（南非肉用美利奴、考力代和中国美利奴绵羊）中的单核苷酸多态性，同时研究该基因对小尾寒羊高繁殖力的影响。

If your computer is equipped with two graphics cards in your CMOS settings to initialize the first PCI video card, and you only take in the AGP display card, of course, the display is not bright.

如果您的电脑装有两个显卡，你在CMOS里设置的是第一个初始化PCI显卡，而你的唯一的显示器接在AGP显卡上，当然显示器是不会亮的。

Results After twelve weeks observation, the observed group's drug efficacy to the symptom of abdomen fullness, epigatric pain, eruct, or epigastric burning was 87%, 87%, 77%, 79%, respectively, while the matched tepronone group's efficacy was 62%, 54%, 46%, 50%, the matched weifuchun group's was 63%,53%,50%, 50% respectively.

上腹烧灼感总有效率联合治疗组为79%，替普瑞酮组为50%(P.05)。联合治疗组组织病理学改善好转率为50%，显效率为43%，总有效率为93%；替普瑞酮组好转率为37%，显效率为33%，总有效率为70%(P.01)；胃复春组好转率为33%，显效率为35%，总有效率为68%(P.01)。

Among them, mutations in exon 7 was highest, while in exon 5 was lowest.

其中以第7号外显子出现的频率最高，第6、8外显子次之，第5外显子最低。

In addition, the expanded memory can easily lead to improper , in order to avoid trouble - in the memory should be expanded to use the same brand, same speed of memory.

除此之外，扩显存不当也很容易导致花屏，为了避免麻烦--在扩显存时应使用相同品牌、相同速度的显存。

I had to buy more photo albums for my friends in China and some make-up mirrors which I did not see yesterday, more cell phone straps, and a JHJ flourescent stick to wave when he was singing.

我要为我中国的朋友多买些写真集，还有显宰照片的化装镜，更多的手机吊坠，还有在显宰唱歌是挥的显宰荧光棒。

According to this desire,a method of frame buffer compression with run-length coding is proposed.

文中据此特性提出了利用游程编码压缩显存数据，并定量讨论了显存压缩比对系统的影响，以及不同应用情况下的显存压缩比。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
