The study included all neonates who were 34 weeks obstetrical estimated gestational age or less born between January 1, 2003 and November 30, 2007 at the Parkland Memorial Hospital in Dallas. Researchers excluded infants who were nonviable, transferred from other nurseries, or had missed critical data points. Of the 2183 newborns included in the study, more than half were hypothermic, defined as a rectal temperature of less than 36.5 °C. Euthermia was defined as a rectal temperature of 36.5 °C to 37.5 °C.

They are presented in need of special curves and surfaces in engineering applications. In order to prove that the uniform C-B-spline basis is normalized totally positive, we compute the matrix which transforms the C-Bézier basis into the uniform C-B-spline and decompose this matrix into a product of. bidiagonal and stochastic factors.

本文用递推的方法，计算出代数三角空间中的n次C-Bézier基与n次均匀C-B-spline基之间的转换矩阵，并把该矩阵分解为一系列二对角阵的乘积，从而证明出n次均匀C-B-spline基是一个标准全正基，进一步用插入节点的方法，把它扩充为一组标准B基，从而我们可以利用B基的很多优良性质，在工程应用中对这两组基进行开发利用。

Furthermore, we give a normalized B-basis by inserting knots.

由于我们的元语言是在C++里定义的，我们必须遵守C/C++的操作符优先级规则。

The additional supplements including glucose,ascorbic acid and insulin had the enhancement effects on C.andersoni development,while folic acid had no significantly effect on C. andersoni development and calcium pantothenate had inhibited effect.When added 50 mmol/L glucose,50μg/ml ascorbic acid,0.3 U/ml insulin into 10%FCS RPMI-1640 medium,the proliferation of C.andersoni had a great significantly increase,and the gene copies of C.andersoni were 8-fold compared with that in 10%FCS RPMI-1640 medium.

冻融法+蛋白酶K法+声裂法提纯隐孢子虫卵囊DNA效果最佳，其次为冻融法+声裂法和蛋白酶K法+声裂法，冻融法+蛋白酶K法效果最差。10%FCS是培养安氏隐孢子虫的最佳FCS浓度，葡萄糖、维生素C和胰岛素都具有促安氏隐孢子虫增殖作用，泛酸钙无促虫体增殖效果，而叶酸则抑制虫体增殖。10%FCS RPMI-1640培养液中加入50 mmol/L葡萄糖，50μg/ml维生素C和0.3 U/ml胰岛素促安氏隐孢子虫增殖效果最显著，虫体增殖8倍。

Winter by means of radioimmunology and in situ hybridazation to probe into the modulation mechanisms of kidney responsing to the winter, and observed effects of pinealectomy. The results show that there are seasonal changes in the level of MT in the Pineal body, serum, hyperthalamus-pituitary-gonadal axis and the same of the third courier---c-fos and the c-jun mRNA expressions in the hyperthalamus-pituitary-gonadal axis from the Summer to the Winter.

首次通过实验，观察了雄性SD大鼠在生理状态下松果体、血清、下丘脑-垂体-睾丸轴褪黑素含量的冬夏变化，下丘脑-垂体-睾丸轴第三信使（c-fos和c-jun）mRNA表达的冬夏变化以及摘除松果体对上述各项指标冬夏变化的影响，实验结果表明，松果体、血清、下丘脑-垂体-睾丸轴褪黑素含量以及下丘脑-垂体-睾丸轴第三信使（c-fos和c-jun）mRNA表达都存在明显的季节性变化。

七月和八月的温度通常是30° C 到40° C（86°–104° F）但夜间就急剧降至17°C 到18° C(58°–60° F)。

The LDL-C/HDL-C ratio had significant difference between CHD group and control group (P.001); cut-off point was 3.89, sensitivity was 79.1%, and specificity 79.8%. Conclusion The LDL-C/HDL-C ratio is a better predicator for CHD; the higher the ratio, the greater the risk of developing coronary disease.

LDL-C/HDL-C比值是粥样硬化性冠脉疾病重要的危险因子之一，明显优于胆固醇或其他血脂的单个含量指标，且随比值的增加，患冠脉疾病的危险性相应增大。

To understand metabolic adaptations,the basal metabolic rate of four small birds in China were investigated.Metabolic rate,body temperature and thermal conductance were determined in yellow-browed bunting Emberiza chrysophrys at a temperature range of 5-35° C,chestnut-flanked white-eye Zosterops erythropleura and hwamei Garrulax canorus at 10-30° C,and red-billed leiothrix Leiothrix lutea at 10-35° C.Oxygen consumption was measured by using a closed circuit respirometer.
