  • 简介:AbstractPsoriasis is considered a systemic disease associated with metabolic abnormalities, and it is important to understand the mechanisms by which metabolism affects pathophysiological processes both holistically and systematically. Metabolites are closely related to disease phenotypes, especially in systemic diseases under multifactorial modulation. The emergence of metabolomics has provided information regarding metabolite changes in lesions and circulation and deepened our understanding of the association between metabolic reprogramming and psoriasis. Metabolomics has great potential for the development of effective biomarkers for clinical diagnosis, therapeutic monitoring, prediction of the efficacy of psoriasis management, and further discovery of new metabolism-based therapeutic targets.

  • 简介:这篇文章检验危险驱动在软件和密码的算法的硬件实现之间的分析攻击。包括一个Atmel89S82528位处理器和0.25m的代表性的平台1.8v标准房间电路被建议实现进展加密标准(AES)。基于模拟的试验性的环境被造获得力量数据,和单个小点的微分力量分析(DPA),并且多小点DPA和关联驱动分析(CPA)攻击分别地在二实现上被进行。试验性的结果证明硬件实现让更少的数据依赖者驱动漏抵抗力量攻击。而且,一条改进DPA途径被建议。它作为力量模型采用中间的结果的hamming距离并且安排纯文本输入区分力量踪迹到最大的概率。与原来的力量攻击相比,我们的改进DPA与可接受的力量大小和更少计算在AES硬件实现上执行成功的攻击。

  • 简介:AbstractPericyte, a kind of pluripotent cell, may regulate the irrigation flow and permeability of microcirculation. Pericytes are similar to the smooth muscle cells, which express several kinds of contractile proteins and have contractility. The dysfunction of pericytes is related to many microvascular diseases, including hypoxia, hypertension, diabetic retinopathy, fibrosis, inflammation, Alzheimer's disease, multiple sclerosis, and tumor formation. For a long time, their existence and function have been neglected. The distribution, structure, biomarker, related signaling pathways as well as the roles of pericytes on vascular diseases will be introduced in this review.
