1History and Progress of the North American Soil Geochemical Landscapes Project,2001-2010显示文摘In 2007,the U.S.Geological Survey,the Geological Survey of Canada,and the Mexican Geological Survey initiated a low-density(1 site per 1600 km2,13323 sites) geochemical and mineralogical survey of North American soils(North American Soil Geochemical Landscapes Project).Sampling and analytical protocols were developed at a series of workshops in 2003-2004 and pilot studies were conducted from 2004-2007.The ideal sampling protocol at each site includes a sample from 0-5 cm depth,a composite of the soil A horizon,and a sample from the soil C horizon.The <2-mm fraction of each sample is analyzed for Al,Ca,Fe,K,Mg,Na,S,Ti,Ag,Ba,Be,Bi,Cd,Ce,Co,Cr,Cs,Cu,Ga,In,La,Li,Mn,Mo,Nb,Ni,P,Pb,Rb,Sb,Sc,Sn,Sr,Te,Th,Tl,U,V,W,Y,and Zn by inductively coupled plasma-mass spectrometry and inductively coupled plasma-atomic emission spectrometry following a near-total digestion in a mixture of HCl,HNO3,HClO4,and HF.Separate methods are used for As,Hg,Se,and total C on this same size fraction.The major mineralogical components are determined by a quantitative X-ray diffraction method.Sampling in the conterminous U.S.was completed in 2010(c.4800 sites) with chemical and mineralogical analysis currently underway.In Mexico,approximately 66% of the sampling(871 sites) had been done by the end of 2010 with completion expected in 2012.After completing sampling in the Maritime provinces and portions of other provinces(472 sites,7.6% of the total),Canada withdrew from the project in 2010.Preliminary results for a swath from the central U.S.to Florida clearly show the effects of soil parent material and climate on the chemical and mineralogical composition of soils.A sample archive will be established and made available for future investigations.David B.Smith William F.Cannon Laurel G.Woodruff Francisco Moreira Rivera Andrew N.Rencz Robert G.Garrett 2012地学前缘2012,19,3:7

9Evaluation of alfalfa inter-seeding effect on bahiagrass baleage fermentation and lactating Holstein performance显示文摘Background:Previous research indicates that bahiagrass may be successfully conserved as baleage,but nutritive value is typically low for lactating dairy cows.The purpose of this study was to determine the effect of adding modest amounts of alfalfa forage(22%),achieved by inter-seeding alfalfa into an existing bahiagrass pasture,on baleage nutritive value and lactation performance of Holstein cows.Forage treatments employed were monoculture bahiagrass baleage(MBB;negative control),bahiagrass-alfalfa mixture baleage(BAB) and conventional corn silage(CCS;positive control).Thirty six mid lactation Holstein cows[34.8 ±5.8 kg 3.5%fat-corrected milk and 112 ± 19 d in milk(DIM)]were stratified according to milk yield and DIM and assigned randomly to 1 of 3 forage treatments.Cows were trained to Calan feeding gates and were offered a common CCS-based TMR in a 10-d covariance period followed by a 42-d treatment feeding period.Results:The BAB contained more protein and less NDF than MBB(12.6 vs 10.3%CP and 71.8 vs 76.6%NDF).Diet DMI was similar for MBB and BAB(19.5 vs 21.6 kg/hd/d),but cows consumed more of the CCS diet(25.5 kg/hd/d)than either baleage-based diet.Cows offered BAB tended to produce more milk than cows offered MBB based TMR(28.4 vs 26.1 kg/hd/d),but both baleage diets generated less milk than CCS-based diets(33.1 kg/hd/d).Milk cumpusition was similar across diets except for milk protein concentrations which were higher tor CCS than either MBB or BAB diets;however,milk urea nitrogen(MUN) was lowest for cows fed CCS diets.Cow BW gain was higher for BAB than MBB implying that a portion of the higher energy contributed by the alfalfa was being used to replenish weight on these mid lactation cows.Conclusions:Data from this study indicate that alfalfa inter-seeded in bahiagrass sod that produces BAB with as little as 22%alfalfa may improve nutritive value compared to monoculture bahiagrass baleage and marginally improve lactation performance of Holstein cows.However,the CCS diet was vastly superior to either MBB or BAB-based diets for milk production.Michael E McCormick Kun Jun Han Vinicius R Moreira David C Blouin 2014Journal of Animal Science and Biotechnology2014,5,4:1

18Needle knife fstulotomy in flat and diverticular papillae:Is it time for redemption?显示文摘Background: European Society of Gastrointestinal Endoscopy( ESGE) recommends needle-knife fstulotomy(NKF) as the preferred precut technique in cases when standard cannulation techniques fail. Despite scarce scientifc evidence, flat and diverticular papillae are thought not to be ideal for NKF, as they are associated with poor outcomes. The present study aimed to determine the outcomes of the use of NKF in relation to flat and intradiverticular papillae. Methods: This prospective multicenter study enrolled consecutive patients, evidencing na?ve flat(group A, n = 49) or diverticular papilla(group B, n = 28), who underwent NKF after failure of standard cannulation techniques. Diverticular morphology was subdivided into intradiverticular(group B1, n = 14) and diverticular border papillae(group B2, n = 14), using a previously validated endoscopic classifcation of the major papilla. The success of biliary cannulation at initial endoscopic retrograde cholangiopancreatography(ERCP), overall biliary cannulation, overall cannulation time, and the rate of adverse events were assessed in the study. Results: The initial cannulation rates were 93.9%, 64.3% and 71.4% for group A, B1, and B2, respectively( P = 0.005);overall cannulation rates after a second ERCP were 98.0%, 92.9% and 85.7%, respectively( P = 0.134). Adverse events occurred in 11.7% of patients, with post-ERCP pancreatitis(PEP) being the most common adverse event(10.4%). Although there was a trend towards a higher incidence of PEP in flat papillae, univariate and multivariate analyses did not show any signifcant relationship between pancreatitis and trainee involvement, papillary morphology, nor overall cannulation time. Conclusions: Although flat papillae are associated with high success rates of biliary cannulation using NKF, the rate of PEP is not negligible. NKF is feasible in diverticular papillae, but it is associated with a modest success rate in the initial ERCP.João Fernandes Jorge Canena Marta Moreira Gonçalo Alexandrino Luísa Figueiredo Tarcísio Araújo Luís Lourenço David Horta Luís Lopes 2022Hepatobiliary & Pancreatic Diseases International2022,21,2:0
19Colon and rectal cancer:An emergent public health problem显示文摘Colorectal cancer ranks third globally,with a high mortality rate.In the United States,and different countries in Europe,organized population screenings exist and include people between 50 and 74 years of age.These screenings have allowed an early diagnosis and consequently an improvement in health indicators.Colon and rectal cancer(CRC)is a disease of particular interest due to the high global burden associated with it and the role attributed to prevention and early diagnosis in reducing morbidity and mortality.This study is a review of CRC pathology and includes the most recent scientific evidence regarding this pathology,as well as a diagnosis of the epidemiological situation of CRC.Finally,the recommendation from a public health perspective will be discussed in detail taking into account the context and the most current recommendations.Marina Pinheiro David Nascimento Moreira Michele Ghidini 2024World Journal of Gastroenterology2024,30,7:0
