致癌的

There are carcinogenic effects of substances through the placenta, but also the possible carcinogenic effects.

有致癌作用的物质经过胎盘，也有产生致癌作用的可能。

With the methods of Reverse transcription-PCR and cDNA sequencing, the expression of FHIT gene was detected in radiation carcinogenesis. The results show that: 1, The FHIT gene's sequence in normal BALB/c mice compare with the sequence of mice in Ge neBank which absents exon 3, but the function of FHIT protien doesn't alter.

结果发现：1、正常BALB／c 小鼠的FHIT基因序列同GeneBank中小鼠的FHIT基因序列比较缺少了外显子 3，但其表达的蛋白功能并未发生改变；2、FHIT基因在辐射损伤与辐射致癌的早期过程中，对照组血液、胸腺及骨髓均未出现异常的FHIT转录本的表达，不同剂量照射组中血液、胸腺及骨髓均有部分样品出现分子量较小的异常FHIT 转录本的表达。

Fat drippings create smoke that is filled with carcinogenic polycyclic aromatic hydrocarbons, or PAHs. When the smoke envelopes the food, it transfers the PAHs onto the surface of the meat. And when meat, chicken and fish are grilled at high temperatures for long periods of time, compounds inside the food react and create heterocyclic amines, or HCAs. HCAs are worrisome because in lab studies they've been shown to trigger breast, colon and prostate tumors in rats and mice.

滴下来的油脂产生的烟雾充满了致癌的多环芳烃，简称PAHs，当烟雾环绕在食物周围的时候，这些多环芳烃也附着在了食物的表面，当猪肉，鸡肉或是鱼肉在长时间的高温烧烤时，这些食物本身所含有的成分产生了化学变化生成杂环胺类物质，简称HCAs，这类物质相当的麻烦，因为实验室研究发现它们会引起大鼠和小鼠乳腺，结肠以及前列腺部位的肿瘤。

Hazardous waste is any discarded material, liquid or solid, that contains the substances to be fatal, toxic, carcinogenic, ignitable, corrosive, or explosive to humans.

危险废物就是指任何含有对人类致命的，有毒的，致癌的，可燃，腐蚀性的，或爆炸的物质的废弃材料、液体或固体。

Hazardous waste is any discard ed material, liquid or solid, that contains the substances to be fatal, toxic, carcinogenic, ignitable, corrosive, or explosive to humans.

危险废物就是指任何含有对人类致命的，有毒的，致癌的，可燃，腐蚀性的，或爆炸的物质的废弃材料、液体或固体。

And the third is the kind of iron in red meat .

第三个因素就是红肉中所含的铁的种类，言下之意是有些类型的铁致癌，有的就不致癌，因此说所有食物中的铁都致癌显然是错的。

The type of iron available in red meat also may enhance tumor formation.

烹调或处理过的红肉中已知的可以致癌的物质可以导致动物的乳腺肿瘤的增长，同时也已被怀疑能导致人类患上乳腺癌。

Objective:The purpose of the experiment was to study the carcinogenic and mutagenic effects of petroleum asphalt.

目的：研究石油沥青有无致突变和致癌作用。方法：选用大鼠经口急性毒性试验、Ames试验、小鼠经口微核试验、大鼠气管注入及兔经皮涂抹致癌试验，研究石油氧化及直馏沥青的急性毒性以及致癌和致突变作用。

Definitely. Cigarettes contain a lot of carcinogens like nicotine and tar. The ad compares lungs to a sponge. If you could wring out the cancer- producing tar, that goes into the lungs of a pack-a -day smoker every year, this is how much you'd get

是阿，菸里面有许多尼古丁、焦油等致癌物质，这支广告就是如果把肺比喻成海绵，如果一天吸一包菸，一整年下来，肺中的致癌焦油真的可以挤出这麼一大杯焦油呢！

Oncogenes were first discovered in certain retroviruses and were later identified AS cancer-causing agents in many animals.

致癌基因首先发现于特定的反转录病毒，后来在许多动物中被认定为致癌因子。

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。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
