Catalytic oxidation is an energy efficient and economical way to get rid of volatile organic compound (VOC) emissions. Sungkono et al have developed a new type of catalyst for VOC treatment, which consists of catalytic substances dispersed on a porous alumina film, and the total oxidation of toluene was obtained at 350 ℃. Stainless steel has many applications in indsutry for its high anti-corrosion properties and compact oxide coating after anodizing. However, there is little relevant information published on VOC treatment. In this paper, we report a novel noble metal catalyst supported on stainless steel treated by anodic oxidation for VOC removal. The catalyst showed excellent activity for toluene combustion at the low temperature of 210 ℃ even after calcination at 1 000 ℃.

为实现小提花织物的疵点检测,提出了一种基于视觉显著性的疵点定位与分割方法。针对小提花织物的花型具有周期性的特点,通过对织物图像进行快速傅里叶变换和形态滤波来抑制正常花纹的显著性,突出疵点区域的显著性,以获取图像的全局显著图;然后使用基于图论的视觉显著模型来计算图像的局部显著图,并对全局和局部显著图进行合并生成综合显著图;最后使用最大熵法对综合显著图进行分割,以得到疵点目标。实验结果表明,在对横裆、破洞、断头、打结和跳花等5种瑕疵进行测试时,该方法的正确率高达93.5%,非常适合于对小提花织物进行疵点检测。

The aim was to investigate the molecular mechanisms responsible for the inducible nitric oxide synthase （iNOS） gene expression stimulated by lipid associated membrane proteins （LAMPs） of Ureaplasma urealytictan （ U. urealyticum ）. Detection of NO, the expression of iNOS and the activation of nuclear factor κB （NF-κB） in direct response to U. urealyticum LAMPs in a murine macrophages, the effects of pyrrolidine dithiocarbamate （PDTC）, an inhibitor of NF-κB and of cycloheximide （CHX）, a protein synthase inhibitor were available. The results indicated that U. urealyticum LAMPs stimulated mouse macrophages to express iNOS and thus produce NO in dose- and time-dependent manner by activating NF-κB. The expression of iNOS, NO production and the activation of NF-κB were inhibited by U. urealyticum LAMPs combination with PDTC or CHX. In conclusion, our findings suggest that U. urealyticum may be an etiological factor to certain diseases due to its ability to stimulate the expression of iNOS, which is probably mediated through the activation of NF-κB.

Ischemic stroke is a cerebrovascular disease associated with high mortality and disability rates. Since the inflammation and immune response play a central role in driving ischemic damage, it becomes essential to modulate excessive inflammatory reactions to promote cell survival and facilitate tissue repair around the injury site. Various cell types are involved in the inflammatory response, including microglia, astrocytes, and neutrophils, each exhibiting distinct phenotypic profiles upon stimulation. They display either proinflammatory or anti-inflammatory states, a phenomenon known as ‘cell polarization.’ There are two cell polarization therapy strategies. The first involves inducing cells into a neuroprotective phenotype in vitro, then reintroducing them autologously. The second approach utilizes small molecular substances to directly affect cells in vivo. In this review, we elucidate the polarization dynamics of the three reactive cell populations(microglia, astrocytes, and neutrophils) in the context of ischemic stroke, and provide a comprehensive summary of the molecular mechanisms involved in their phenotypic switching. By unraveling the complexity of cell polarization, we hope to offer insights for future research on neuroinflammation and novel therapeutic strategies for ischemic stroke.

由于影像间显著的几何和辐射差异,多源遥感影像自动匹配一直是目前研究的难点问题。首先引入具有光照和对比度不变性的相位一致性模型,并对其进行扩展,构建相位一致性的特征方向信息,然后借助于梯度方向直方图的模板结构,利用其特征值和特征方向,建立一种局部特征描述符——局部相位一致性方向直方图(local histogram of orientated phase congruency,LHOPC),最后利用欧氏距离作为匹配测度进行同点名识别。对四组多源遥感影像进行试验,其结果表明,相比于尺度不变特征转换和加速鲁棒性特征算法,LHOPC能更为有效的抵抗影像间的辐射差异,提高了匹配性能。
