1Helicobacter pylori and oral pathology:Relationship with the gastric infection显示文摘Helicobacter pylori(H.pylori)has been found in the oral cavity and stomach,and its infection is one of the most frequent worldwide.We reviewed the literature and conducted a Topic Highlight,which identified studies reporting an association between H.pylori-infection in the oral cavity and H.pylori-positive stomach bacterium.This work was designed to determine whether H.pylori is the etiologic agent in periodontal disease,recurrent aphthous stomatitis(RAS),squamous cell carcinoma,burning and halitosis.Record selection focused on the highest quality studies and meta-analyses.We selected 48 articles reporting on the association between saliva and plaque and H.pylori-infection.In order to assess periodontal disease data,we included 12 clinical trials and 1 meta-analysis.We evaluated 13 published articles that addressed the potential association with RAS,and 6 with squamous cell carcinoma.Fourteen publications focused on our questions on burning and halitosis.There is a close relation between H.pylori infection in the oral cavity and the stomach.The mouth is the first extra-gastric reservoir.Regarding the role of H.pylori in the etiology of squamous cell carcinoma,no evidence is still available.Isabel Adler Andrea Muio Silvia Aguas Laura Harada Mariana Diaz Adriana Lence Mario Labbrozzi Juan Manuel Muio Boris Elsner Alejandra Avagnina Valeria Denninghoff 2014World Journal of Gastroenterology2014,20,29:21
2Mediterranean Berries as Inhibitors of Lipid Oxidation in Porcine Burger Patties Subjected to Cooking and Chilled Storage显示文摘The efficiency of extracts from Arbutus unedo L.(AU),Crataegus monogyna L.(CM),Rosa canina L.(RC),and Rubus ulmifolius Schott.(RU)to inhibit lipid oxidation in raw,cooked and cooked and chilled(2°C/12 d)porcine burger patties,was investigated.The modification of the fatty acid profile during processing treatments(cooking and chilling),the quantitative measurements of thiobarbituric acid reactive substances(TBA-RS),and lipid-derived volatiles,were used as indicators of lipid oxidation.Polyunsaturated fatty acids(PUFA)gradually decreased during cooking and the subsequent storage of cooked burger patties with this decrease being significantly greater(P<0.05)in control patties than in those with added berry extracts.In accordance,the control patties showed significantly higher TBA-RS numbers and counts of lipid-derived volatiles in all treatments when compared to the berry-added counterparts(P<0.05).Results from the present work show,for the first time,that extracts from A.unedo,C.monogyna,R.canina,and R.ulmifolius are promising antioxidants which could enhance the nutritional,safety and sensory properties of porcine burger patties.Rui Ganho Mario Estévez Mónica Armenteros David Morcuende 2013Journal of Integrative Agriculture2013,12,11:16
3Integration of Probabilistic and Multi-Hazard Risk Assessment Within Urban Development Planning and Emergency Preparedness and Response: Application to Manizales,Colombia显示文摘The details of a multi-hazard and probabilistic risk assessment, developed for urban planning and emergency response activities in Manizales, Colombia, are presented in this article. This risk assessment effort was developed under the framework of an integral disaster risk management project whose goal was to connect risk reduction activities by using open access and state-of-theart risk models. A probabilistic approach was used for the analysis of seismic, landslide, and volcanic hazards to obtain stochastic event sets suitable for probabilistic loss estimation and to generate risk results in different metrics after aggregating in a rigorous way the losses associated to the different hazards. Detailed and high resolution exposure databases were used for the building stock and infrastructure of the city together with a set of vulnerability functions for each of the perils considered. The urban and territorial ordering plan of the city was updated for socioeconomic development and land use using the hazard and risk inputs and determinants, which cover not only the current urban area but also those adjacent areas where the expansion of Manizales is expected to occur. The emergency response capabilities of the city were improved by taking into account risk scenarios and after updating anautomatic and real-time post-earthquake damage assessment.Gabriel A.Bernal Mario A.Salgado-Gálvez Daniela Zuloaga Julián Tristancho Diana González Omar-Darío Cardona 2017International Journal of Disaster Risk Science2017,8,3:4
4室外空气污染、早产和低出生体重:世界卫生组织孕产妇和围产期保健全球调查分析显示文摘[背景]吸入细颗粒物(颗粒物直径≤2.5μm,PM2.5)能诱发氧化应激和炎症反应,并有可能导致早产和其他不良的围产期结局。[目的]检测2004—2008年,世界卫生组织在全球22个国家中进行的孕产妇和围产期保健调查中,室外PM2.5是否与不良妊娠结局相关。[方法]以有新生儿出生的各医疗诊所周围50 km为半径的圆弧缓冲区计算室外PM2.5的长期均值(2001—2006年)。应用广义估计方程确定诊所的PM2.5水平与个体的早产和低出生体重之间的相关性,调整个人、诊所和国家水平的季节性因素及潜在的混杂因素。另外还对各国中的相关性进行了研究。[结果]在所有国家中,调整季节性因素后,PM2.5与早产无关联,但是与低出生体重相关[PM2.5的第四个四分位数段(〉20.2μg/m3)与第一个四分位数(〈6.3μg/m3)相比,比值比(OR)=1.22;95%CI:1.07-1.39]。中国是PM2.5测量值范围最大的国家,早产和低出生体重均仅与PM2.5的最高四分位数段相关,提示可能存在阈值效应(PM2.5≥36.5μg/m3与PM2.5〈12.5μg/m3相比,早产和低出生体重比值比分别为:OR=2.54;CI:1.42-4.55和OR=1.99;CI:1.06-3.72)。[结论]室外PM2.5浓度与低出生体重相关,但与早产不相关。在快速发展的国家中,例如中国,最高的空气污染水平可能与两个结局都相关。Nancy L.Fleischer Mario Merialdi Aaron van Donkelaar Felipe Vadillo-Ortega Randall V.Martin Ana Pilar Betran Jo?o Paulo Souza Marie S.O'Neill 王晓宇 汪源 金泰廙 2014环境与职业医学2014,31,12:4

6Probabilistic Seismic Risk Assessment in Manizales,Colombia: Quantifying Losses for Insurance Purposes显示文摘A fully probabilistic seismic risk assessment was developed in Manizales, Colombia, considering assets of different types. The first type includes elements that are part of the water and sewage network, and the second type includes public and private buildings. This assessment required the development of a probabilistic seismic hazard analysis that accounts for the dynamic soil response,assembling high resolution exposure databases, and the development of damage models for different types of elements. The economic appraisal of the exposed assets was developed together with specialists of the water utilities company of Manizales and the city administration. The risk assessment was performed using several Comprehensive Approach to Probabilistic Risk Assessment modules as well as the R-System, obtaining results in terms of traditional metrics such as loss exceedance curve, average annual loss, and probable maximum loss. For the case of pipelines, repair rates were also estimated. The results for the water and sewage network were used in activities related to the expansion and maintenance strategies, as well as for the exploration of financial retention and transfer alternatives using insurance schemes based on technical,probabilistic, and prospective damage and loss estimations.In the case of the buildings, the results were used in the update of the technical premium values of the existing collective insurance scheme.Mario A.

8Identification of patients at-risk for Lynch syndrome in a hospital-based colorectal surgery clinic显示文摘AIM:To determine the prevalence of a family history suggestive of Lynch syndrome (LS) among patients with colorectal cancer (CRC) followed in a coloproctology outpatient clinic in Southern Brazil.METHODS:A consecutive sample of patients with CRC were interviewed regarding personal and family histories of cancer.Clinical data and pathology features of the tumor were obtained from chart review.RESULTS:Of the 212 CRC patients recruited,61 (29%) reported a family history of CRC,45 (21.2%) were diagnosed under age 50 years and 11 (5.2%) had more than one primary CRC.Family histories consistent with Amsterdam and revised Bethesda criteria for LS were identified in 22 (10.4%) and 100 (47.2%) patients,respectively.Twenty percent of the colorectal tumors had features of the high microsatellite instability phenotype,which was associated with younger age at CRC diagnosis and with Bethesda criteria (P < 0.001).Only 5.3% of the patients above age 50 years had been previously submitted for CRC screening and only 4% of patients with suspected LS were referred for genetic risk assessment.CONCLUSION:A significant proportion of patients with CRC were at high risk for LS.Education and training of health care professionals are essential to ensure proper management.Patrícia Koehler-Santos Patricia Izetti Jamile Abud Carlos Eduardo Pitroski Silvia Liliana Cossio Suzi Alves Camey Cláudio Tarta Daniel C Damin Paulo Carvalho Contu Mario Antonello Rosito Patricia Ashton-Prolla Joāo Carlos Prolla 2011World Journal of Gastroenterology2011,17,6:2
9Efficient metallization of magnetite concentrate by reduction with agave bagasse as a source of reducing agents显示文摘The reduction behavior and metallization degree of magnetite concentrate with agave bagasse were investigated in an inert atmosphere.The effects of temperature,biomass content,and residence time on reduction experiments and metallization degree were investigated by X-ray diffraction and scanning electron microscopy.Compared with other types of biomass,agave bagasse had lower contents of nitrogen,sulfur,and ash.X-ray diffraction analysis showed that the metallization degree improved with increasing temperature and biomass content.Complete metallization was achieved at 1100℃ for 30 min with 65:35 and 50:50 ratios of the magnetite concentrate to the agave bagasse.These results demonstrate that agave bagasse promotes the efficient metallization of magnetite concentrate without the external addition of a reducing agent.Therefore,this biomass is a technical suitable alternative to replace fossil fuels in steelmaking.Diana Cholico-González NoemíOrtiz Lara Mario Alberto Sánchez Miranda Ricardo Morales Estrella Ramiro Escudero García Carlos ALeón Patiño 2021International Journal of Minerals,Metallurgy and Materials2021,28,4:2
