骨骼的

Researchers from the University of Cambridge, the Animal Health Trust in Newmarket, and the BAM Federal Institute of Materials Research and Testing, Berlin, have discovered that the characteristic toughness and stiffness of bone is predominantly due to the presence of specialized sugars, not proteins, as had been previous believed.

科学家最近发现人类骨骼的结构和之前所认为的有很大不同，这将对某些骨骼衰退性疾病的治疗提供帮助。来自Newmarket剑桥大学Animal Health Trust以及柏林BAM材料研究和测试联邦研究所的科学家发现，骨骼的特征刚韧性和硬度主要取决于专门的糖类，而非之前普遍认为的蛋白。

The proximal end of a bone.of or relating to or forming or attached to a skeleton .

骨骼的，关于骨骼的，形成骨骼的，或依附于骨骼的。

This has laid the foundation for the extraction of skeletal characteristics and the bone classification in the future.

为将来骨骼特征的提取和骨骼的分类奠定了基础。

A posteroanterior cephalogram was taken for every subject at the same time each year, lasting for 6 years. Computer aided cephalometrics was carried out. Results: 1. In adolescents with normal occlusion, the total variation range of the upper and middle face symmetry in transverse and vertical d...

结果表明：正常人上、中面部骨骼存在对称性的正常变异，其范围在 1 3— 1 8岁保持稳定，水平向小于 8%，垂直向不超过 9mm；在其相对于颅底的位置关系及其骨骼各对应部位之间，有较好对称性；面部骨骼的生长发育具有潜在的优势特点。

Pregnant 50 day onward, FOXC2 mainly expressed in dorsal aorta, arch arteries, archae-endocardium and cells of vertebrae rudiment. The expression of FOXC2 could be seen in cordis great vessels, endocardium, chondrocyte and periost of axial skeleton during pregnant 70 days, and only in primary ossification center of axial skeleton and coronary artery during pregnant 80 day.

孕50天后表达于背主动脉、弓形动脉和原始心脏内膜、锥体雏形细胞；孕70天时，在心脏大血管、心内膜和中轴骨骼的软骨细胞和骨膜细胞表达；孕80天时仅表达于中轴骨骼的骨化中心和冠状动脉。

Measurements of the length of the hindlimb bones indicated that the tibiotarsus is invariably the largest among the three major leg bones.

即在所有鸟类的后肢骨骼中，胫跗骨的长度占3块骨骼的比例为最大；地栖鸟类后肢骨骼中股骨的长度要短于跗跖骨；树栖鸟类后肢骨骼中股骨的长度要长于跗跖骨。

Breast cancer commonly metastasizes to bones, producing both osteolytic and osteoblastic deposits. Different markers for quantitative determination of bone turnover have been developed to evaluate bone metastases of breast cancer. The urinary deoxypyridionline, a crosslink product of collagen molecules found in bone and excreted in urine during bone degradation, and bone specific alkaline phosphatase, an isoenzyme localized in the membrane of osteoblasts and released in circulation during bone formation, were recently described as a group of markers of bone turnover in metastatic cancer.

乳癌患者常见骨髓转移造成溶骨性及成骨性沈积物，而利用不同标记来定量骨质转换形态，可以评估乳癌骨骼转移的变化，而尿液中Deoxypyridinoline是骨质内胶原分子在骨骼破坏分解时至尿中的产物，骨特殊碱性磷酸酵素是一种同形酵素，位於成骨细胞的外膜且在骨骼形成时释放至血液中，利用此两种生化标记，可以来预测乳癌转移至骨骼的转换情形。

These prostate cancer bony metastases show an increased expression of the PTH receptor, and PTH promotes the growth and invasiveness of prostate cancer cells in bone. Hence, these blastic metastases appear to induce a "vicious cycle," in which PTH resorbs normal bone to support the growth of blastic bone.

这些转移到骨骼的摄护腺癌，其PTH受体的表现是增加的，且PTH促进骨骼中摄护腺癌细胞的生长与侵入性，因此，这些骨塑型的转移显然会造成一种恶性循环，PTH会分解正常的骨骼，以支撑骨塑骨骼的生长。

The distribution of medusae on the colony is not even, with very low densities on the margin of the colony, but high densities on the middle portion.

另外水母体在群体骨骼的分布并非均匀分布，在群体骨骼的边缘密度很低，而中段位置密度较高。

Bone remodeling appears to be governed by a feedback system in which the bone cells sense the state of strain in the bone matrix around them and either add or remove bone as needed to maintain the strain within normal limits.

骨骼的重新塑造由一套反馈系统管理，在该系统中，骨骼细胞感觉到它周围的骨骼基质的拉紧状况，按照需要要么增加要么移动骨骼来在标准范围中维持这个状况。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
