1Review of the biological and engineering aspects of algae to fuels approach显示文摘Current biofuel production relies on limited arable lands on the earth,and is impossible to meet the biofuel demands.Oil producing algae are alternative biofuel feedstock with potential to meet the world’s ambitious goal to replace fossil fuels.This review provides an overview of the biological and engineering aspects in the production and processing technologies and recent advances in research and development in the algae to fuels approach.The article covers biology,selection and genetic modification of algae species and strains,production systems design,culture media and light management,harvest and dewatering,downstream processing,and environment and economic assessment.Despite the many advances made over several decades,commercialization of algal fuels remains challenging chiefly because of the techno-economic constraints.Technological breakthroughs in all major aspects must take place before commercial production of algal fuels becomes economically viable.Paul Chen Min Min Yifeng Chen Liang Wang Yecong Li Qin Chen Chenguang Wang Yiqin Wan Xiaoquan Wang Yanling Cheng Shaobo Deng Kevin Hennessy Xiangyang Lin Yuhuan Liu Yingkuan Wang Blanca Martinez Roger Ruan 2009International Journal of Agricultural and Biological Engineering2009,2,4:9
2Effects of terlipressin versus splenectomy on liver regeneration after partial hepatectomy in rats: What we know so far?显示文摘We read with great interest the article entitled ‘‘Comparative study of the effects of terlipressin versus splenectomy on liver regeneration after partial hepatectomy in rats’’ by Ulmer et al. [1]. The aim of this study was to analyse the impact of terlipressin versus splenectomy on postoperative liver function and liver regeneration in rats undergoing 70% partial hepatectomy. Ulmer and his colleagues concluded that neither the administration of terlipressin nor splenectomy improved liver regeneration after 70% partial hepatectomy in rats. This is a very interesting research in our understanding regarding the study of postoperative liver failure and liver regeneration after modulation of portal vein pressure. However, there are some questions which demand further consideration.antonios athanasiou eleftherios spartalis mairead hennessy michael spartalis demetrios moris christos damaskos emmanouil pikoulis 2018Hepatobiliary & Pancreatic Diseases International2018,17,1:5
3Randomized study comparing incidence of radial artery occlusion post-percutaneous coronary intervention between two conventional compression devices using a novel airinflation technique显示文摘AIM To compare post-percutaneous coronary intervention(PCI) radial artery occlusion(RAO) incidence between two conventional radial artery compression devices using a novel air-inflation technique.METHODS One hundred consecutive patients post-PCI were randomized 1:1 to Safeguard or TR band compression devices. Post-radial sheath removal, each compression device was inflated with additional 2 m L of air above index bleeding point during air-filled device application and gradually down-titrated accordingly. RAO was defined as absence of Doppler flow signal performed at 24 h and at 6 wk post-PCI. Patients with missing data were excluded. Statistical significance was defined as P < 0.05.RESULTS All patients had 6 F radial sheath inserted. No significant differences were observed between Safeguard Radial(n = 42) vs TR band(n = 42) in terms of age(63 ± 11 years vs 67 ± 11 years), clinical presentation(electives, n = 18 vs n = 16; acute coronary syndrome, n = 24 vs n = 26) and total procedural heparin(7778 ± 2704 IU vs 7825 ± 2450 IU). RAO incidence was not significantly different between groups at 24 h(2% vs 0%, P = 0.32) and 6 wk(0%, both).CONCLUSION Safeguard Radial and TR band did not demonstrate significant between-group differences in short-term RAO incidence. Lack of evidence of RAO in all postPCI patients at 6 wk follow-up, regardless of radial compression device indicate advantage of using the novel and pragmatic air-inflation technique. Further work is required to more accurately confirm these findings.Victor Voon Muhammad Ayyaz Ul Haq Ciara Cahill Kirsten Mannix Catriona Ahern Terence Hennessy Samer Arnous Thomas Kiernan 2017World Journal of Cardiology2017,9,11:5
4Catalytic microwave assisted pyrolysis of aspen显示文摘The effect of catalysts on the microwave pyrolysis of aspen pellets was studied.A range of chlorides,nitrates and metal-oxides were added at 2%of the aspen mass(air dry aspen pellet weight basis).Chlorides in particular were found to favor liquid yield,especially the yield of water phase residue.Average liquid yield with added chlorides was 41%mass of the total biomass input,compared to 35%mass without catalyst.Metal-oxides were found to favor pyrolysis heavy oil,and thus total oil yield,since the yield of light oils seemed to be fairly constant.Nitrates were found to favor pyrolysis gas production.Pure light oils and light oils blended with diesel were found to be a potential diesel fuel substitute.Johannes Moen Changyan Yang Bo Zhang Hanwu Lei Kevin Hennessy Yiqin Wan Zhiping Le Yuhuan Liu Paul Chen Roger Ruan 2009International Journal of Agricultural and Biological Engineering2009,2,4:5

6Fractionation and characterization of bio-oil from microwave-assisted pyrolysis of corn stover显示文摘Bio-oil from thermochemical conversion of biomass is a complex mixture of polar and non-polar compounds,and cannot be used directly as a combustion engine fuel due to its low heating value,high viscosity,chemical instability,and incomplete volatility.Mixed-solvent extraction was developed to fractionate bio-oils from microwave-assisted pyrolysis of corn stover to produce light oil(a mixture of light and inflammable fuel oil components from bio-oil)with low viscosity and low combustion residue,and high value chemicals.Different fractions from bio-oil were characterized using GC/MS and TG,and a major chemical(hydroxy-butanedioic acid diethyl ester)was separated.Changyan Yang Bo Zhang Johannes Moen Kevin Hennessy Yuhuan Liu Xiangyang Lin Yiqin Wan Hanwu Lei Paul Chen Roger Ruan 2010International Journal of Agricultural and Biological Engineering2010,3,3:4

8Diagnostic accuracy of tests for Helicobacter pylori in an Alaska Native population显示文摘AIM:To evaluate the accuracy of two non-invasivetests in a population of Alaska Native persons. Highrates of Helico bacter pylori(H. pylori) infection,H. pylori treatment failure,and gastric cancer in this population necessitate documentation of infection status atmultiple time points over a patient's life.METHODS:In 280 patients undergoing endoscopy,H. pylori was diagnosed by culture,histology,rapidurease test,13C urea breath test(UBT) ,and immuno-globulin G antibodies to H. pylori in serum. The performances of 13C-UBT and antibody test were compared to a gold standard defined by a positive H. pylori testby culture or,in case of a negative culture result,bypositive histology and a positive rapid urease test.RESULTS:The sensitivity and specificity of the 13C-UBT were 93% and 88%,respectively,relative to thegold standard. The antibody test had an equivalents ensitivity of 93% with a reduced specificity of 68%.The false positive results for the antibody test were as-sociated with previous treatment for an H. pylori infection [relative risk(RR) = 2.8]. High levels of antibodiesto H. pylori were associated with chronic gastritis and male gender,while high scores in the 13C-UBT testwere associated with older age and with the H. pyloribacteria load on histological examination(RR = 4.4) .CONCLUSION:The 13C-UBT out performed the anti-body test for H. pylori and could be used when a non-invasive test is clinically necessary to document treatment out come or when monitoring for reinfection.Dana L Bruden Michael G Bruce Karen M Miernyk Julie Morris Debby Hurlburt Thomas W Hennessy Helen Peters Frank Sacco Alan J Parkinson Brian J McMahon 2011World Journal of Gastroenterology2011,17,42:3
9Conduit necrosis following esophagectomy: An up-to-date literature review显示文摘Esophageal conduit ischaemia and necrosis is an uncommon but devastating complication of esophagectomy and remains one of the most challenging issues in surgical practice. The incidence, time interval to develop symptoms, and clinical presentation are highly variable with no predictable pattern. Evidence comes from case reports and case series rather than randomized controlled trials.We describe the issues surrounding conduit necrosis affecting the stomach,jejunum and colon as an esophageal replacement and the advantages,disadvantages and challenges of each type of reconstruction. Diagnosis is challenging for the most experienced surgeon. Upper gastrointestinal endoscopy and computed tomography thorax with both oral and intravenous contrast is the gold standard. Management, either conservative or interventional is also a difficult decision. Management options include conservative treatment and more aggressive treatments such as stent insertion, surgical debridement and repair of the esophagus using jejunum, colon or a musculocutaneous flap. In spite of recent advances in surgical techniques, there is no reliable strategy to manage esophageal conduit necrosis. Our review covers the pathophysiology and clinical significance of esophageal necrosis while highlighting current techniques of prevention, diagnosis and treatment of this life-threatening condition.Antonios Athanasiou Mairead Hennessy Eleftherios Spartalis Benjamin H L Tan Ewen A Griffiths 2019World Journal of Gastrointestinal Surgery2019,11,3:2
