The purpose of this article is to report that some anti-A1 that react at 37°C are IgG antibodies and are clinically significant, as they can cause the destruction of a proportion of A1 cells in vivo following the transfusion of red blood cells. Therefore, when a serum of an individual contains anti-A1, further testing of the plasma against group A1, A2, and O by referencing red blood cells and individual cells against anti-A1 lectin (Dolichos biflorus lectin) must be performed. Confirming the specificity of anti-A1 by referencing red blood cells is also important in selecting the appropriate blood for transfusion. ABO antibodies are naturally occurring and activate the complement cascade, making them more likely to cause severe transfusion reactions compared to antibodies to other RBC antigens.

当前移动通信产业需要能够在整个应用频段上运行的天线系统,无需添加外部系统来控制谐振器的偏移,制造成本最低,且增益和效率等电特性更佳。因此,与同一用途的其它天线相比,微带贴片天线具有易于制造和成本低的优良特性。超材料是具有负介电常数和导磁率的人造结构,这意味着其折射率为负值。由于这些不寻常的性能,超材料可以改变电磁波的电磁特性,当超材料被用于制造微波元件和天线时,可以增强其某些所需特性。此外,由于超材料的结构单元尺寸小于传导波长的四分之一,元件尺寸可以得到小型化。本文设计了新型双负超材料微带天线,提出了使用双负超材料来制作平面微带天线。通过创建单元结构可以获得负折射率特性。单元结构可以看成是由一系列的电容器和电感器组合构成,导线导致负介电常数,微带间隙导致负磁导率,负介电常数和磁导率导致了负折射率。与自然界容易获得的材料相比,这一性能显得尤为特别。通过采用有规则的环形超材料结构,该方法可以应用于制作微带贴片天线。针对不同的频率,微带贴片天线的增益和带宽是通过创建超材料的不同形状来改善的。超材料的形状从简单的欧米茄和U形,到复杂的以C形和U形的新颖组合形状。在5G频段28 GHz情况下,本文使用不同形状的超材料进行天线性能的设计,获得了天线增益、回波损耗、辐射模式和方向性等方面的性能增加。

Composites formed by adding nano-scale particles to a polymer matrix results in improving electrical, mechanical, and thermal properties of the composite. Good tribological properties can be obtained for polymers filled with nano-scale fillers compared to that filled with micro-scale particles. The friction and wear resistance of these composites is found to increase with increasing filler concentration. It is also possible to use multi-functional fillers to develop high performance composites which cannot be achieved by using a single filler.

Background:A two-compound product containing calcipotriol and betamethasone dipropionate (Daivobet./Dovobet.) has been evaluated in a large clinical trial programme, providing a wealth of data on the treatment of psoriasis vulgaris. Objective:To determine the effectiveness of the two-compound product in patients with mild, moderate and severe psoriasis vulgaris. Methods:Data from over 1,534 patients with psoriasis vulgaris who received the two-compound product once daily for at least 4 weeks in four randomised, double-blind studies were pooled. A meta-analysis of the pooled data is presented. Severity of psoriasis at baseline was determined by investigator assessment and Psoriasis Area and Severity Index (PASI) score. Results:For patients with severe disease defined by PASI score (PASI baseline ≥17), the mean reduction in PASI after up to 4 weeks of treatment was 71.6%compared with 68.9 and 67.2%for those with moderate (PASI baseline 5.1-16.0) and mild disease (PASI baseline ≤5). Corresponding reductions for investigator-assessed severity were 72.6, 69.1 and 68.7%, respectively. Conclusion:Although the metaanalysis of the data from these four studies was performed post hoc, we may conclude that the two-compound product provided highly effective treatment of psoriasis,regardless of the category of baseline disease severity.
