目的评估食用超加工食品与心血管疾病发生风险的前瞻性关联。方法基于人群的队列研究。背景NutriNet-Santé队列,法国2009—2018年。参与者年龄≥18岁的105159位受试者。应用重复24小时的膳食记录(平均每人5.7小时)收集受试者饮食摄入情况,用以记录受试者日常对于3300种食品的摄入情况。根据加工程度利用NOVA分级将这些食品进行分类。主要结局测量在校正已知风险因素后,利用多变量Cox比例风险模型评估食用超加工食品与总体心血管疾病及冠状动脉性心脏病、脑血管疾病发生风险的关系。结果研究的中位随访时间为5.2年,其间食用超加工食品与总体心血管疾病[1409例患病,超加工食品在饮食中所占百分比绝对增加10%的危险比为1.12(95%可信区间为1.05~1.20);P<0.01,518208人年;食用超加工食品量最多的受试者(Q4)其总体心血管疾病发病率为277/10万人年,而在食用量最少的受试者(Q1)中为242/10万人年]、冠状动脉心脏病[665例患病;危险比1.13(1.02~1.24);P=0.02,520319人年;在超加工食品食用量最多和最少者的发病率分别为124/10万人年和109/10万人年]及脑血管疾病[829例患病;危险比1.11(1.01~1.21);P=0.02,520023人年;超加工食品食用量最多和最少者的发病率分别为163/10万人年和144/10万人年]的发病高风险有关。在校正了数种膳食营养质量标记(饱和脂肪酸、钠与糖摄入量、膳食纤维或者是来自主成分分析的健康饮食模式)的影响及大范围灵敏度分析后,这些结果仍存在统计学显著性。结论这项大型观察性研究发现,食用大量超加工食品与心血管疾病、冠状动脉性心脏病及脑血管疾病的高发病风险相关。这些结果仍需要在其他人群或研究单位进行验证,并且因果关系仍待确定。食品加工中的多种因素,如终产品的营养成分、添加剂、接触材料和新污染物,可能在这种联系中发挥某种作用,其各自作用的大小仍需要进一步研究。同时,几个国家的公共卫生当局近期已经开始鼓励人们食用未经加工或者经简单加工的食品,并且限制超加工食品的摄入。研究注册*** NCT03335644。

目的:探讨上海常驻居民最小红斑量(minimal erythema dose, MED)与年龄、性别、皮肤日光反应类型、肤色指标、个体类型角及体质指数的关系。方法:使用GS2004多波段SPF测试日光模拟器对受试者背部进行长波紫外线(UVA)+中波紫外线(UVB)波段照射,并测定健康受试者背部MED值,并采集肤色、皮肤类型及体质指数等信息,采用t检验与线性回归分析采集指标与MED间的关联。测试光源波段来源于国际标准化组织(ISO)24444:2010防晒化妆品防晒指数人体测试方法。结果:共纳入受试者222名,MED均值为(22.52±5.41)mJ/cm2。研究发现:MED值与年龄、个体类型角、体质指数呈负相关(P0.05)。结论:在上海常驻居民中,肤色越浅、年龄越大、体质指数越高对紫外线越敏感。本研究为进一步阐明MED值的生理机制和精准预测提供了一定的理论基础。

《1864—1865年经济学手稿》中,马克思开创了危机理论许多方面的研究先河。关于1866年危机的草稿和笔记本进一步呈现出马克思危机理论的主要轮廓。在编辑工作中,恩格斯意识到了客观事物本身发生的变化以及马克思19世纪60年代所作文本的后续结论。尽管留有遗憾,恩格斯仍然抓住了《资本论》把握资本主义生产方式更为普遍的特征之目的。

This paper presents a methodology based on computational intelligence techniques for classification of hydrological cycles that can infer the change in the physico-chemical parameters and metals from the water of a reservoir in the Amazon. The methodology initially consists in perform a pre-processing the data to select the most relevant variables of the samples. After that, we compared two different machine learning classifiers, namely SVM (support vector machine) and ANN (artificial neural network). The automatic model selection is made to choose the parameters of the classifiers. The results indicate that the support vector machine classifier using radial basis function or polynomial kernel exhibited superior results to ANN in terms of overall accuracy and robustness. The SVM classifier accuracy (89.1%) can be considered satisfactory, since there is a great variability of physico-chemical parameters and metals in the hydrological cycles and in the different ecosystems where are the sampling station.

In this work compounds of gadolinium-doped ceria, Ce0.9Gd0.1O1.95 (CGO) and NiO were synthesized by polymeric precursor method. NiO-Ce0.9Gd0.1O1.95 composite was attained by mixture of the powders of the both phases calcinated already. The precursor powders were characterized by simultaneous thermogravimetry-differential thermal analysis and the calcined materials were studied by X-ray diffraction, scanning electronic microscopy, Fourier transform infrared spectroscopy and dilatometry. The refinement of the diffraction data indicated that the powders were crystallized in the wanted phases. All the produced powders had nanometric and sub micrometric features. The produced composite showed good characteristics for the use as anode for SOFC.
