4Design of 16S rRNA gene primers for 454 pyrosequencing of the human foregut microbiome显示文摘AIM:To design and validate broad-range 16S rRNA primers for use in high throughput sequencing to classify bacteria isolated from the human foregut microbiome.METHODS:A foregut microbiome dataset was constructed using 16S rRNA gene sequences obtained from oral,esophageal,and gastric microbiomes produced by Sanger sequencing in previous studies represented by 219 bacterial species.Candidate primers evaluated were from the European rRNA database.To assess the effect of sequence length on accuracy of classification,16S rRNA genes of various lengths were created by trimming the full length sequences.Sequences spanning various hypervariable regions were selected to simulate the amplicons that would be obtained using possible primer pairs.The sequences were compared with full length 16S rRNA genes for accuracy in taxonomic classification using online software at the Ribosomal Database Project (RDP).The universality of the primer set was evaluated using the RDP 16S rRNA database which is comprised of 433 306 16S rRNA genes,represented by 36 phyla.RESULTS:Truncation to 100 nucleotides(nt)downstream from the position corresponding to base 28 in the Escherichia coli 16S rRNA gene caused misclassification of 87(39.7%)of the 219 sequences,compared with misclassification of only 29(13.2%)sequences with truncation to 350 nt.Among 350-nt sequence reads within various regions of the 16S rRNA gene,the reverse read of an amplicon generated using the 343F/798R primers had the least(8.2%)effect on classification.In comparison,truncation to 900 nt mimicking single pass Sanger reads misclassified 5.0%of the 219 sequences.The 343F/798R amplicon accurately assigned 91.8%of the 219 sequences at the species level.Weighted by abundance of the species in the esophageal dataset,the 343F/798R amplicon yielded similar classification accuracy without a significant loss in species coverage(92%).Modification of the 343F/798R primers to 347F/803R increased their universality among foregut species.Assuming that a typicalpolymerase chain reaction can tolerate 2 mismatches between a primer and a template,the modified 347F and 803R primers should be able to anneal 98%and 99.6%of all 16S rRNA genes in the RDP database.CONCLUSION:347F/803R is the most suitable pair of primers for classification of foregut 16S rRNA genes but also possess universality suitable for analyses of other complex microbiomes.Carlos W Nossa William E Oberdorf Jφrn A Aas Bruce J Paster Todd Z DeSantis Eoin L Brodie Daniel Malamud Michael A Poles Zhiheng Pei 2010World Journal of Gastroenterology2010,16,33:16
5Neuroendocrine tumors of the gastrointestinal tract: Case reports and literature review显示文摘Neuroendocrine tumors(NET)previously called carcinoid tumors are neoplasms of enterochromaffin/neuroendocrine cell origin which display neurosecretory capacity that may result in the carcinoid syndrome.The annual incidence of patients with NET is 8.4 per 100000;yet many NET remain asymptomatic and clinically undetected.A majority of NET follows a benign course;however,some will display malignant characteristics.NET most commonly occur in the gastrointestinal tract(67%)and bronchopulmonary system(25%).Gastrointestinal NET occur within the stomach,small intestine,liver,and rectum.We report a retrospective study of 11 subjects:Eight with benign carcinoid tumors:duodenal bulb(n=2),terminal ileum(n=1),sigmoid colon(n=2),and rectum(n=3);three with malignant carcinoid:liver(n=1)and intra-abdominal site(n=2).The diagnosis,endoscopic images,outcome,treatment and review of the literature are presented.William J Salyers Kenneth J Vega Juan Carlos Munoz Bruce W Trotman Silvio S Tanev 2014World Journal of Gastrointestinal Oncology2014,6,8:8

7Discussions on rockburst and dynamic ground support in deep mines显示文摘The paper is a summary of discussions on four topics in rockburst and dynamic ground support.Topic 1 is the mechanisms of rockburst.Rockburst events are classified into two categories in accordance with the triggering mechanisms,i.e.strain burst and fault-slip burst.Strain burst occurs on rock surfaces when the tangential stress exceeds the rock strength in hard and brittle rocks.Fault-slip burst is triggered by fault-slip induced seismicity.Topic 2 is prediction and forecasting of rockburst events.Prediction for a rockburst event must tell the location,timing and magnitude of the event.Forecasting could simply foresee the probability of some of the three parameters.It is extremely challenging to predict rockbursts and large seismic events with current knowledge and technologies,but forecasting is possible,for example the possible locations of strain burst in an underground opening.At present,the approach using seismic monitoring and numerical modelling is a promising forecasting method.Topic 3 is preconditioning methods.The current preconditioning methods are blasting,relief-hole drilling and hydrofracturing.Defusing fault-slip seismicity is difficult and challenging but has been achieved.In very deep locations(>3000 m),the fracturing could extend from the excavation face to a deep location ahead of the face and therefore preconditioning is usually not required.Topic 4 is dynamic ground support against rockburst.Dynamic ground support requires that the support system be strong enough to sustain the momentum of the ejecting rock on one hand and tough enough on the other hand to absorb the strain and seismic energies released from the rock mass.The current dynamic support systems in underground mining are composed of yielding tendons and flexible surface retaining elements like mesh/screen and straps.Yielding props and engineered timber props are also used for dynamic support.Charlie C.Li Peter Mikula Brad Simser Bruce Hebblewhite William Joughin Xiaowei Feng Nuwen Xu 2019Journal of Rock Mechanics and Geotechnical Engineering2019,11,5:5

16A new perspective on quiet Sun magnetism显示文摘The Hinode mission has provided us with a new, quantitative view of the magnetism of the quiet Sun. It has revealed that the quiet internetwork areas are blanketed by horizontal fields that appear at first sight to have more flux than the vertical fields resolved on the same 0.3 size scale. These measurements point to the possibility that the horizontal fields might be the primary source of the 'hidden turbulent flux' of the quiet Sun anticipated from Hanle effect depolarization. In this paper, evidence is presented suggesting that the 'seething' horizontal fields observed by Harvey in 2007 and the horizontal fields revealed by Hinode are the same phenomenon. Because the seething fields appear to be of uniform fluctuation over the whole disk, the phenomenon is most likely not associated with the dynamo source of solar activity. Thus, the small-scale 'hidden turbulent flux' lends support to the notion of a local solar dynamo acting on granular sizes and time scales.LITES Bruce William 2009Science China(Physics,Mechanics & Astronomy)2009,52,11:2
