1一种缓冲回填材料的筛选及其特性:西班牙实例(英文)显示文摘介绍了西班牙在高放废物深地质处置中用于缓冲回填材料的泥岩的筛选及其特性的研究成果,这项研究在西班牙核废料管理委员会资助下进行,始于 20 世纪 80 年代,且在开始阶段主要是开展泥岩沉积层及黏土供应商的筛选工作。黏土这些特性与标准已被国际社会广泛接受,但进一步的研究主要涉及到泥岩的矿物纯度、持水特性、可塑性、低渗透性、较高的膨胀压力和热导性。经初步研究,确定两种膨润土沉积层被选中,并在实验室中对其特性进行了研究,主要包括:热–水–力特性的确定、预加热和温度的影响以及石英添加剂的作用。由于膨润土具有较高的膨胀性以及低渗透性,因而必须对传统的试验技术进行改进,并设计出新的试验设备。最终确定Cortijo de Archidona(Almería)选为西班牙膨润土的供应区,其开采的膨润土已在近期结束的数个研究课题中得到了应用。无论是从矿物学、热学、水力学、力学和地质化学,还是从可变性等方面看来,该区膨润土的特性都是最好的;另外,处置库中膨润土的变化特征在实验室以及现场都已经作了相应的研究。Villar María Victoria Astudillo Julio Huertas Fernando 2006岩石力学与工程学报2006,25,4:6

3Inheritance patterns of secondary symbionts during sexual reproduction of pea aphid biotypes显示文摘食草的昆虫经常怀有影响他们的生态学和进化的细菌的共生者。蚜虫招待应尽的 endosymbiont Buchnera,它为复制被要求,和其频率越过蚜虫人口变化的容许的共生者。这些似母亲播送了第二等的共生者特别地在豌豆蚜虫被学习了, Acyrthosiphon pisum,哪个港口穿上环境地依赖的效果的至少 8 不同细菌的种类(不数的 Buchnera ) 主人健康。特别地,这些共生者种类与豌豆蚜虫人口在特定的植物上喂被联系。尽管他们是继承的似母亲,这些细菌偶尔越过昆虫系被转移。如此的 nonmaternal 转移的一机制在性复制期间是到子孙的父亲的传播。迄今为止,第二等的共生者的传播在仅仅蚜虫系和 3 共生者种类的一把在蚜虫的性复制期间被调查了。更好描绘这个过程,我们通过包含属于 9 专业化主人的遗传因子型,和 117 个十字的 49 克隆的一个交叉实验在豌豆蚜虫的性复制期间调查了 7 共生者种类的继承模式。在子孙的共生者种类在从鸡蛋并且在以后的单性生殖的代孵化的 fundatrix 阶段与诊断质的 PCR 被检测。我们没发现共生者的父亲的传播的证实的案例到子孙,并且我们观察到特别共生者种(Serratia symbiotica ) 的母亲的传播是相当低效的。我们在尊重讨论这些观察到豌豆蚜虫的生态学。Jean Peccoud Joêl Bonhomme Frédérique Mahéo Manon de la Huerta Olivier Cosson Jean-Christophe Simon 2014Insect Science2014,21,3:4
4Cognitive disorder and dementia in type 2 diabetes mellitus显示文摘Insulin,a key pleiotropic hormone,regulates metabolism through several signaling pathways in target tissues including skeletal muscle,liver,and brain.In the brain,insulin modulates learning and memory,and impaired insulin signaling is associated with metabolic dysregulation and neurodegenerative diseases.At the receptor level,in aging and Alzheimer’s disease(AD)models,the amount of insulin receptors and their functions are decreased.Clinical and animal model studies suggest that memory improvements are due to changes in insulin levels.Furthermore,diabetes mellitus(DM)and insulin resistance are associated with age-related cognitive decline,increased levels ofβ-amyloid peptide,phosphorylation of tau protein;oxidative stress,pro-inflammatory cytokine production and dyslipidemia. Recent evidence shows that deleting brain insulin receptors leads to mildobesity and insulin resistance without influencing brain size and apoptosis development.Conversely, deleting insulin-like growth factor 1 receptor (IGF-1R) affects brain size anddevelopment, and contributes to behavior changes. Insulin is synthesized locally in the brain andis released from the neurons. Here, we reviewed proposed pathophysiological hypotheses toexplain increased risk of dementia in the presence of DM. Regardless of the exact sequence ofevents leading to neurodegeneration, there is strong evidence that mitochondrial dysfunctionplays a key role in AD and DM. A triple transgenic mouse model of AD showed mitochondrialdysfunction, oxidative stress, and loss of synaptic integrity. These alterations are comparable tothose induced in wild-type mice treated with sucrose, which is consistent with the proposal thatmitochondrial alterations are associated with DM and contribute to AD development. Alterationsin insulin/IGF-1 signaling in DM could lead to mitochondrial dysfunction and low antioxidantcapacity of the cell. Thus, insulin/IGF-1 signaling is important for increased neural processing andsystemic metabolism, and could be a specific target for therapeutic strategies to decreasealterations associated with age-related cognitive decline.Genaro G Ortiz Miguel Huerta Héctor A González-Usigli Erandis D Torres-Sánchez Daniela LC Delgado-Lara Fermín P Pacheco-Moisés Mario A Mireles-Ramírez Blanca MG Torres-Mendoza Roxana I Moreno-Cih Irma E Velázquez-Brizuela 2022World Journal of Diabetes2022,13,4:2
5Large gangliocytic paraganglioma of the duodenum:A rare entity显示文摘Gangliocytic paragangliomas are rare tumors that almost exclusively occur within the second portion of the duodenum. Although these tumors generally have a benign clinical course, they have the potential to recur or metastasize to regional lymph nodes. The case report presented here describes a 57-year-old female patient with melena, progressive asthenia, anemia, and a mass in the second-third portion of the duodenum that was treated by local excision. The patient was diagnosed with a friable bleeding tumor. The histologic analysis showed that the tumor was a 4 cm gangliocytic paraganglioma without a malignant cell pattern. In the absence of local invasion or distant metastasis, endoscopic resection represents a feasible, curative therapy. Although endoscopic polypectomy is currently considered the treatment of choice, it is not recommended if the size of the tumor is > 3 cm and/or there is active or recent bleeding. Patients diagnosed with a gangliocytic paraganglioma should be closely followed-up for possible local recurrence.Alejandra Gordillo Hernández Eduardo Dominguez-Adame Lanuza Auxiliadora Cano Matias Rosario Perez Huertas Katherine Maria Gallardo Rodriguez Purificacion Gallinato Perez Fernando Oliva Mompean 2015World Journal of Gastrointestinal Surgery2015,7,8:2

9Sport participation and vigilance in children:Influence of different sport expertise显示文摘Purpose: The present study aimed to investigate the relationship between different types of sport expertise(externally-paced vs. self-paced sports) and vigilance performance in children by evaluating the cardiovascular fitness level of the participants.Methods: Three groups of children(11.0 § 0.2 years) differentiated in terms of their regular sport participation(football players, n = 20; track and field athletes, n = 20; non-athletic controls, n = 20) took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In another session, participants completed the Psychomotor Vigilance Task(PVT) to evaluate their vigilance performance under 2 conditions of velocity demands(normal vs. speed).Results: The results revealed that both groups of sport practitioners had higher cardiovascular fitness than non-athlete controls. In contrast, no significant differences in the performance PVT were found between track and field athletes and controls. Crucially, football players showed better performance in the PVT than track and field athletes and controls. These between-group differences were not modulated by the speed demands of the task.Conclusion: The major novel finding of this research points to a positive relationship between sport participation and vigilance performance during childhood. We discuss our results in terms of the different hypotheses put forward in the literature to explain the relationship between regular exercise and cognitive functioning: the 'cardiovascular fitness' and the 'cognitive component skills' hypotheses.rafael ballester florentino huertas enrique molina daniel sanabria 2018Journal of Sport and Health Science2018,7,4:2
