Detection of KRAS G12D in colorectal cancer stool by droplet digital PCR

AIM To assess KRAS G12 D mutation detection by droplet digital PCR(dd PCR) in stool-derived DNA from colorectal cancer(CRC) *** In this study, tumor tissue and stool samples were collected from 70 patients with stage Ⅰ-Ⅳ CRC diagnosed by preoperative biopsy. KRAS mutational status was determined by pyrosequencing analysis of DNA obtained from formalin-fixed paraffinembedded(FFPE) tumor tissues. The KRAS G12 D mutation was then analyzed by dd PCR in FFPE tumors and stool-derived DNA from patients with this point mutation. Wild-type(WT) tumors, as determined by pyrosequencing, were included as controls; analysis of FFPE tissue and stool-derived DNA by dd PCR was performed for these patients as *** Among the total 70 patients included, KRAS mutations were detected by pyrosequencing in 32(45.71%), whereas 38(54.29%) had WT tumors. The frequency of KRAS mutations was higher in left-sided tumors(11 located in the right colon, 15 in the left, and 6 in the rectum). The predominant point mutation was KRAS G12 D(14.29%, n = 10), which was more frequent in early-stage tumors(I-IIA, n = 7). In agreement with pyrosequencing results, the KRAS G12 D mutation was detected by dd PCR in FFPE tumor-derived DNA, and only a residual number of mutated copies was found in WT controls. The KRAS G12 D mutation was also detected in stool-derived DNA in 80% of all fecal samples from CRC patients with this point mutation. CONCLUSION dd PCR is a reliable and sensitive method to analyze KRAS G12 D mutation in stool-derived DNA from CRC patients, especially at early stages. This non-invasive approach is potentially applicable to other relevant biomarkers for CRC management.

Prophylaxis with ketotifen in rats with portal hypertension:involvement of mast cell and eicosanoids

BACKGROUND:Since we have previously shown an increase of mast cells in the small bowel and in the mesenteric lymph nodes in the rats with prehepatic portal hypertension,it can be hypothesized that this essential inflammatory cell would be involved in the pathogeny of the splanchnic changes related to portal hypertension. METHODS:To verify this hypothesis,we first studied mast cell infiltration in the ileum and in the mesenteric lymph nodes in sham-operated male Wistar rats(n=12) and in short-term prehepatic portal hypertensive rats (n=12),and the serum levels of rat mast cell protease Ⅱ(RMCP-Ⅱ)by *** a second set of experiments ketotifen,a mast cell stabilizer drug,was administered to sham-operated(n=10)and portal hypertensive(n=12) rats 24 hours before the intervention and prostanoids (PGE2,PGI2,TXB2)and leukotrienes(LTC4,LTB4)were assayed by RIA,mast cell infiltration in the ileum and in the mesenteric lymph nodes and the serum levels of RMCP-Ⅱwere also studied,to show its effectiveness to prevent the mesenteric alterations produced by the inflammatory mediators released by the mast cell. RESULTS:Forty-eight hours after the intervention RMCP-Ⅱ (P<0.05),PGE2(P<0.001)and LTC4 serum levels decreased and mast cell number and RMCP-Ⅱlevels increased in mesenteric lymph nodes in portal hypertensive *** administration of ketotifen reduced portal pressure(P<0.001),serum levels of PGE2(P<0.001)and RMCP-Ⅱ(P<0.001)in mesenteric lymph nodes. CONCLUSIONS:In acute portal hypertension in the rat,the mast cell translocation from intestinal mucosa to mesenteric lymph nodes,where they are activated and degranulates,would represent a defence mechanism to avoid the activation of an acute and massive inflammatory response in this *** administration of ketotifen is able to reduce the splanchnic inflammatory changes related to acute portal hypertension in the rat.

Simulations of Colliding Uniform Density H2 Clouds

引用

International Journal of Astronomy and Astrophysics 2014年第1期4卷 192-220页

作者： Guillermo Arreaga-garcía jaime Klapp Julio Saucedo Morales Departamento de Investigación en Física Universidad de Sonora Hermosillo Mexico Instituto Nacional de Investigaciones Nucleares Ocoyoacac Mexico

In this paper we present a set of numerical simulations designed to study the interaction process of HII molecular clouds. For the initial conditions we assume head-on and oblique collisions of binary identical clouds placedadjacent to one another, with their surfaces just in contact. The colliding initial clouds are uniform density molecular gas spheres with rigid body rotation. The cloud initial conditions are chosen to favor its gravitational collapse as an isolated system. To study the effect of the self-gravity of the cloud in the collision process, we consider several models in which the approaching speed of the colliding clouds increases from zero up to several times the initial sound speed of the barotropic gas. We present the outcome of these collision models for several values of the impact parameter b, which depends on the initial radius of the cloud. We have explored the parameter space of the approaching velocity Vapp of the colliding clouds for configurations that may result in seeds for the formation of more complex systems. Such systems are expected to include filaments and gas clumps, where the star formation process is still possible despite the occurrence of the collision. We show hereby that collisions may have a major and favorable influence on the star formation process.

半干旱地中海地区人工林和天然林的林牧业系统管理经常使用季节性的夜间畜栏来保护动物。这种管理制度改变了动物排泄物的空间分布,导致土壤矿产资源的净转移和在畜栏内的积累。畜栏被遗弃后,荒地植物代替了畜栏,成为它们在森林中传播的集中来源。我们的目的是在更好地了解废弃畜栏后植被生长过程的基础上,对季节性畜栏进行合理管理,以减轻其对森林的负面影响。本论文研究了以色列内盖夫(Negev)西北半干旱地区的人工桉树林(Eucalyptus)在废弃畜栏后的时间序列上,植被、土壤种子库和土壤养分水平的时间变化关系,并与附近的对照样地进行比较。该地区为双季节地中海型气候,放牧区内一年生物种占据优势。研究结果表明,废弃的羊畜栏被原产于旧的废弃畜栏的荒草种子定殖。在废弃畜栏土壤资源耗竭的驱动下,随后的演变速度缓慢,在畜栏废弃后20年仍在继续。荒草首先是被较高的草,然后是矮草所取代,但大多数为非禾草的杂类草植物,特别是在这一时期没有恢复的地下芽植物。畜栏内原有草本植被的恢复是通过种子从周围植被中扩散,而不是从废弃后留在畜栏内的原始土壤种子库中恢复。在人工林放牧区中的荒草物种可视为具有斑块性的集合种群。它们的持久性依赖于不断创造新的畜栏来补偿旧的废弃畜栏中逐渐减少的种群,以及依赖于传播路径的有效性。

GBP-WAHSN:A Group-Based Protocol for Large Wireless Ad Hoc and Sensor Networks

引用

Journal of Computer Science & Technology 2008年第3期23卷 461-480页

作者： jaime Lloret Miguel garcia Jesus Tomás Fernando Boronat Department of Communications Polytechnic University of ValenciaCamino Vera s/n46022ValenciaSpain

Grouping nodes gives better performance to the whole network by diminishing the average network delay and avoiding unnecessary message forwarding and additional overhead. Many routing protocols for ad-hoc and sensor networks have been designed but none of them are based on groups. In this paper, we will start defining group-based topologies, and then we will show how some wireless ad hoc sensor networks （WAHSN） routing protocols perform when the nodes are arranged in groups. In our proposal connections between groups are established as a function of the proximity of the nodes and the neighbor＇s available capacity （based on the node＇s energy）. We describe the architecture proposal, the messages that are needed for the proper operation and its mathematical description. We have also simulated how much time is needed to propagate information between groups. Finally, we will show a comparison with other architectures.
