高血压的饮食疗法

高血压有无声的杀手之称,这是因为血压过高可引起诸如心力衰竭、动脉粥样硬化和脑溢血等疾病。高血压的最主要的发病原因是精神紧张。此外,生活方式不规则、吸烟、酗酒、浓茶、咖啡、可乐、过多的食盐、高脂肪低纤维和过份精细而又缺乏营养的食物,以及动脉硬化、肥胖、糖尿病、严重便秘和过多地使用止痛药,均可引起高血压。高血压病人应多吃新鲜水果和蔬菜,以助体内毒素的排出。水果可选择柑桔、苹果、梨、芒果、番石榴、菠萝和西瓜等。蔬菜可选择黄瓜、番茄、洋葱、萝卜、甘蓝和菠菜等。能生吃的蔬菜尽量生吃。大蒜是可以最有效地降低…

An Improved Computational Prediction Model for Lysine Succinylation Sites Mapping on Homo sapiens by Fusing Three Sequence Encoding Schemes with the Random Forest Classifier

Background Lysine succinylation is one of the reversible protein post-translational modifications (PTMs), which regulate the structure and function of proteins. It plays a significant role in various cellular physiologies including some diseases of human as well as many other organisms. The accurate identification of succinylation site is essential to understand the various biological functions and drug development.Methods In this study, we developed an improved method to predict lysine succinylation sites mapping on Homo sapiens by the fusion of three encoding schemes such as binary, the composition of k-spaced amino acid pairs (CKSAAP) and amino acid composition (AAC) with the random forest (RF) classifier. The prediction performance of the proposed random forest (RF) based on the fusion model in a comparison of other candidates was investigated by using 20-fold cross-validation (CV) and two independent test datasets were collected from two different sources.Results The CV results showed that the proposed predictor achieves the highest scores of sensitivity (SN) as 0.800, specificity (SP) as 0.902, accuracy (ACC) as 0.919, Mathew correlation coefficient (MCC) as 0.766 and partial AUC (pAUC) as 0.163 at a false-positive rate (FPR) = 0.10 and area under the ROC curve (AUC) as 0.958. It achieved the highest performance scores of SN as 0.811, SP as 0.902, ACC as 0.891, MCC as 0.629 and pAUC as 0.139 and AUC as 0.921 for the independent test protein set-1 and SN as 0.772, SP as 0.901, ACC as 0.836, MCC as 0.677 and pAUC as 0.141 at FPR = 0.10 and AUC as 0.923 for the independent test protein set-2. It also outperformed all the other existing prediction models.Conclusion The prediction performances as discussed in this article recommend that the proposed method might be a useful and encouraging computational resource for lysine succinylation site prediction in the case of human population.     

孕烷X受体的研究进展

核受体是一类高度保守的配体依赖性转录因子家族,在哺乳动物发育、繁殖、免疫应答、心血管功能、组织生长、肿瘤形成、外源物清除及糖类和脂质代谢等生理过程中发挥重要作用。机体对外源物质的清除主要是由孕烷X受体等核受雄介导的。孕烷X受体最早是作为外源物感受器而被研究的,可以被大多数亲脂性药物等外源性化合物及一些内源性化合物如胆汁酸等结构差异很大的配体激活,进而与视黄醇类X受体等形成异源二聚体,结合在ER6、XREM等DNA元件上,调控下游靶基因（包括一相代谢酶、二相结合酶及药物转运体等基因）的表达。此外,孕烷X受体在能量代谢和免疫反应中也有重要作用,参与某些代谢疾病的发生发展,且已在动物模型中被证明是Ⅱ型糖尿病、血脂异常、肥胖症和动脉粥样硬化等代谢疾病治疗的有效靶标。我们主要就其发现、结构、组织分布、作用方式、自身表达的调节等方面的最新研究进行综述。     

Get a grip: Podosomes as potential players in phagocytosis

Podosomes have been known for several decades as micron-sized, F-actin-rich structures that play a pivotal role in cell migration and invasion, as they are able to mediate both cell-matrix attachment as well as extracellular matrix degradation. Particularly in monocytic cells, podosomes have been shown to fulfill a variety of additional functions such as sensing of substrate rigidity and topography, or cell-cell fusion. Increasing evidence now points to the involvement of podosome-like structures also during phagocytosis by immune cells such as macrophages, dendritic cells, and neutrophils. Here, we compare the different cell models and experimental set ups where “phagocytic podosomes” have been described. We also discuss the composition and architecture of these structures, their potential involvement in mechanosensing and particle disruption, as well as the pros and cons for addressing them as bona fide podosomes.

Tissue microarrays as a platform for proteomic investigation

Tissue microarrays have become an essential tool in translational pathology. They are used to confirm results from other experimental platforms, such as expression microarrays, as well as a primary tool to explore the expression profile of proteins by immunohistochemical analysis. Tissue microarrays are routinely used molecular epidemiology, drug development and determining the diagnostic, prognostic and predictive value of new biomarkers. By applying traditional protein based assays, as well as novel assays to the platform, tissue microarrays have gained a new utility as a proteomic tool for both basic science as well as clinical investigation. This article will explore the new approaches that are being applied to tissue microarrays to, characterize the human proteome, and new technologies that allow tissue microarrays to function as a protein array.

SLX4: multitasking to maintain genome stability

The SLX4/FANCP tumor suppressor has emerged as a key player in the maintenance of genome stability, making pivotal contributions to the repair of interstrand cross-links, homologous recombination, and in response to replication stress genome-wide as well as at specific loci such as common fragile sites and telomeres. SLX4 does so in part by acting as a scaffold that controls and coordinates the XPF–ERCC1, MUS81–EME1, and SLX1 structure-specific endonucleases in different DNA repair and recombination mechanisms. It also interacts with other important DNA repair and cell cycle control factors including MSH2, PLK1, TRF2, and TOPBP1 as well as with ubiquitin and SUMO. This review aims at providing an up-to-date and comprehensive view on the key functions that SLX4 fulfills to maintain genome stability as well as to highlight and discuss areas of uncertainty and emerging concepts.
