为了探究一种快速、无损与简便的东北松子品质检测方法,近红外光谱技术被应用到东北松子蛋白质无损检测研究中。利用偏最小二乘法建立带壳松子和去壳松仁的蛋白质定量分析模型,采用求导、多元散射校正、变量标准化校正、矢量归一化预处理方法优化模型,利用反向间隔偏最小二乘法、无信息变量消除法选取特征波段,建立全波段和特征波段下的偏最小二乘蛋白质预测模型。结果表明,带壳松子光谱经矢量归一化预处理方法后构建的模型最优,松仁光谱经变量标准化校正预处理方法后构建的模型最优;波段筛选能够优化模型质量,其中反向间隔偏最小二乘法的筛选结果最优,其带壳松子和松仁蛋白质模型校正集相关系数分别为0.9056和0.9383,验证集均方根误差分别为0.6670和0.5761。由此可知,经过优化后,模型的预测性能得到了提高,为带壳松子和松仁的蛋白质在线检测提供了一定的参考价值。

The glass-ceramics was prepared from coal fly ash, limestone and Na2CO3 by sintering processes. Effects of the crystallization temperature (850–1100 ℃) on crystallization behavior, microstructure, sintering character and chemical stability of the glass-ceramics samples were analyzed by means of DTA, XRD, SEM and other analytical methods. The results show that the main crystalline phase of as-prepared glass-ceramics after crystallization treatment is gehlenite (Ca2Al2SiO7). The species of crystalline phases keep the same, however, the main crystalline intensity, line shrinkage rate and bulk density increase first then decrease with the increasing of heat treatment temperature. Water absorption of the samples was reduced as the heat treatment temperature rising. The glass-ceramics display high performance crystallization properties and chemical stability. The optimized glass-ceramics with desired sintering character and chemical stability was obtained by crystallized at 1050 ℃.

BACKGROUND: Although regulatory T cells(Tregs) are key to the maintenance of immunologic homeostasis and tolerance, little is known about Treg-mediated immunosuppression in the stage of sepsis. This article aimed to review the current literature on the role of Tregs in the pathophysiology of septic response, attempting to investigate the role of Tregs in immune dysfunction during *** SOURCES: A literature search was conducted in January 2014 using the China National Knowledge Infrastructure and Pub Med. Articles on the role of Tregs in immune dysfunction during sepsis were ***: The identified articles indicated that Treg levels can be used for the assessment of the course of sepsis. The inhibition of Treg activity can promote the recovery of immune ***: Since the mechanism of Tregs is complex during the sepsis, more studies are needed.

The CNx thin film was deposited on Si(100) substrate from a saturated acetone solution of cyanuric tri-chloride and melamine (cyanuric trichloride/melamine=1︰1.5) at room temperature. X-ray diffraction (XRD) results showed that the diffraction peaks in the pattern coincided well with those of graphite-like carbon nitride calculated in the literature. The lattice constants (a=4.79 ? c=6.90 ) for g-C3N4 matched with those of ab initio calculations (a=4.74 ? c=6.72 ? quite well. X-ray photoelectron spectroscopy (XPS) measurements indicated that the elements in the de-posited films were mostly of C and N (N/C=0.75), and N (400.00 eV) bonded with C (287.72 eV) in the form of six-member C3N3 ring. The peaks at 800 cm-1, 1310 cm-1 and 1610 cm-1 in the Fourier transform infrared (FTIR) spec-trum indicated that triazine ring existed in the product. These results demonstrated that crystalline g-C3N4 was ob-tained in the CNx film.
