Extracellular RNAs(exRNAs) are novel circulating factors that can be used as biomarkers in various diseases. Their unique and diverse kinds, as well as their role as biomarkers, make them significant biomarkers. There has been immense work carried out since the discovery of exRNAs in circulation and other biological fluids to catalog and determine whether exRNAs may be utilized as indicators for health and illness. In this review, we aim to understand the current state of exRNAs in relation to various diseases and their potential as biomarkers. We will also review current issues and challenges faced in using exRNAs, with clinical and lab trials, that can be used as viable markers for different diseases.

In vitro and in vivo study on fine-grained Mg-Zn-RE-Zr alloy as a biodegradeable orthopedic implant produced by friction stir processing

Magnesium alloys containing biocompatible components show tremendous promise for applications as temporary biomedical devices. However, to ensure their safe use as biodegradeable implants, it is essential to control their corrosion rates. In concentrated Mg alloys, a microgalvanic coupling between the α-Mg matrix and secondary precipitates exists which results in increased corrosion rate. To address this challenge, we engineered the microstructure of a biodegradable Mg-Zn-RE-Zr alloy by friction stir processing (FSP), improving its corrosion resistance and mechanical properties simultaneously. The FS processed alloy with refined grains and broken and uniformly distributed secondary precipitates showed a relatively uniform corrosion morphology accompanied with the formation of a stable passive layer on the alloy surface. In vivo corrosion evaluation of the processed alloy in a small animal model showed that the material was well-tolerated with no signs of inflammation or harmful by-products. Remarkably, the processed alloy supported bone until it healed till eight weeks with a low in vivo corrosion rate of 0.7 mm/year. Moreover, we analyzed blood and histology of the critical organs such as liver and kidney, which showed normal functionality and consistent ion and enzyme levels, throughout the 12- week study period. These results demonstrate that the processed Mg-Zn-RE-Zr alloy offers promising potential for osseointegration in bone tissue healing while also exhibiting controlled biodegradability due to its engineered microstructure. The results from the present study will have profound benefit for bone fracture management, particularly in pediatric and elderly patients.

现代社会依赖于不间断的能源供应,任何中断都可能对社会和经济产生重大影响。在世界各地,与结冰事件有关的输电线路停电都是一个持续出现且频繁发生的问题,尤其是在湿度和海拔较高的地区。架空输电电缆结冰严重威胁电网的安全运行。厚重的冰会压塌塔楼或折断电线,阻碍电力传输,并导致大范围停电,这些停电也可能损害包括医院、学校和交通网络在内的重要基础服务。架空输电线路结冰会造成长期停电和输电系统损坏。在众多除冰装置中,基于模块化多电平换流器的直流除冰器(MMC-DDI)由于其良好的技术性能被认为是一种潜在的解决方案。本文对MMC-DDI的转换器特性进行了定量的分析和计算。文章表明,对于特定的直流除冰需求,变流器的额定电压随交流侧电压的变化而变化,有时远远超过熔化功率。该方案在一台500千伏输电线路的MMC-DDI上进行了测试。我未来的计划是提高它的经济性,为此提出了一种优化配置,即在一定条件下,在变流器的输入交流侧配置合适的变压器。

Are efforts up to the mark? A cirrhotic state and knowledge about HCV prevalence in general population of Pakistan

引用

Asian Pacific Journal of Tropical Medicine 2016年第6期9卷 597-598页

作者： muhammad sohail Afzal Department of Chemistry School of Science University of Management and Technology (UMT)

Pakistan is declared a cirrhotic state by WHO because of high prevalence of Hepatitis C virus(HCV). It is proposed that there are more than 10 million infected individuals in Pakistan. Keeping in mind the scenario, one should expect to have proper surveillance system for HCV monitoring across the country not only for high risk groups but also for general population as well. Monitoring the general population is of considerable help to identify the hot spots for infection spread and will help in designing effective strategies. In this study the current available data from last 6 years is analyzed. The results showed that the range of HCV seroprevalence in general population in Pakistan varied from 3.13%-23.83%. Similarly year wise HCV prevalence showed great variation and the prevalence was 9.57%, 6.04%, 7.46%, 4.9% and 11.04% in 2010, 2011, 2012, 2013 and 2014 respectively. The current analysis declared that available data is not sufficient and is not presenting the original picture of the situation. On these basis, a proper surveillance system is proposed across the country to get an actual picture of the infection for better management in future and massive community education programmes should be warranted in identified hot spots across the country.

研究区块链监管存在的问题是至关重要的。鉴于此,提出了一种分层跨链的监管架构(CHA),设计了“监管链-业务链”跨链协作的以链治链的监管模式。该架构以构建去中心化的监管链的方式改善了信息系统监管的集权特性;以策略层和监管层、业务层分离的方式,实现了监管行为和监管技术的分离,从而保证了区块链监管结构的通用性。最后,通过形式化分析方法论证了该架构的分布式可行性,进而证明了方案在跨链监管可靠性方面的技术可行性、适用于不同监管业务的通用可行性及可扩展性。
