1LAMOST Experiment for Galactic Understanding and Exploration (LEGUE)——The survey's science plan显示文摘We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way galaxy using the Guo Shou Jing Telescope (GSJT, formerly called the Large sky Area Multi-Object fiber Spectroscopic Telescope - LAMOST). The survey will obtain spectra for 2.5 million stars brighter than r < 19 during dark/grey time, and 5 million stars brighter than r < 17 or J < 16 on nights that are moonlit or have low transparency. The survey will begin in the fall of 2012, and will run for at least four years. The telescope's design constrains the optimal declination range for observations to 10 < δ < 50 , and site conditions lead to an emphasis on stars in the direction of the Galactic anticenter. The survey is divided into three parts with different target selection strategies: disk, anticenter, and spheroid. The resulting dataset will be used to study the merger history of the Milky Way, the substructure and evolution of the disks, the nature of the first generation of stars through identification of the lowest metallicity stars, and star formation through study of open clusters and OB associations. Detailed design of the LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) survey will be completed in summer 2012, after a review of the results of the pilot survey.Li-Cai Deng Heidi Jo Newberg Chao Liu Jeffrey L.

2Trans-arterial chemoperfusion for the treatment of liver metastases of breast cancer and colorectal cancer: Clinical results in palliative care patients显示文摘AIM To evaluate the clinical value and efficiency of transarterial chemoperfusion(TACP) in patients with liver metastases from breast cancer(BC) and colorectal cancer(CRC).METHODS We treated 36 patients with liver metastases of BC(n = 19, 19 females) and CRC(n = 17; 8 females, 9 males) with repeated TACP. The treatment interval was 4 wk. TACP was performed with gemcitabine(1000 mg/m2) and mitomycin(10 mg/m2), administered within 1 h after positioning the catheter tip in the hepatic artery. Before treatment, the size, location, tumour volume, vascularization and number of liver tumours were evaluated using magnetic resonance imaging(MRI). Tumour response was evaluated according to the Response Evaluation Criteria in Solid Tumors guidelines.RESULTS TACP using gemcitabine and mitomycin for metastases from CRC and BC was performed without any serious side effects. The follow-up MRI showed a therapeutic response in 84.2% of the BC patients-stable disease 47.4% and partial response 36.8%. A progression was seen in 15.8%.CRC patients showed a therapeutic response in 52.9% of cases. A progression of the disease was documented in 47.1% of the patients with CRC. These data show that TACP in patients with liver metastases of BC leads to a significantly better therapeutic response compared with CRC patients(P = 0.042). The median survival time was 13.2 mo for the BC patients, which is significantly longer than for CRC patients at 9.3 mo(P = 0.001).CONCLUSION TACP for liver metastases of BC appears to be a safe and effective palliative treatment with improved outcomes in comparison to patients with CRC.Tatjana Gruber-Rouh Marcel Langenbach Nagy NN Naguib Nour-Eldin M Nour-Eldin Thomas J Vogl Stephan Zangos Martin Beeres 2017World Journal of Clinical Oncology2017,8,4:7

6Green tea extract:A potential cause of acute liver failure显示文摘The use of herbal products has increased significantly in recent years.Because these products are not subject to regulation by the Food and Drug Administration and are often used without supervision by a healthcare provider,the indication for and consumption of these supplements is quite variable.Moreover,their use is generally regarded as safe and natural by the lay-public.Unfortunately,there has been an increase in the number of reported adverse events occurring with the use of herbal products.We present a case of acute impending liver failure in an adolescent male using a weightloss product containing green tea extract.Our case adds to the growing concern surrounding the ingestion of green tea extract and serves to heighten healthcare provider awareness of a potential green tea extract hepatotoxicity.Despite the generally touted benefits of green tea as a whole,clinical concern regarding its use is emerging and has been linked to its concentration in multiple herbal supplements.Interestingly,the suspected harmful compounds are those previously proposed to be advantageous for weight-loss,cancer remedy,and anti-inflammatory purposes.Yet,we emphasize the need to be aware of not just green tea extract,but the importance of monitoring patient use of all dietary supplements and herbal products.Shreena S Patel Stacey Beer Debra L Kearney Garrett Phillips Beth A Carter 2013World Journal of Gastroenterology2013,19,31:3

14Central line-associated bloodstream infection among children with biliary atresia listed for liver transplantation显示文摘BACKGROUND Pre-transplant nutrition is a key driver of outcomes following liver transplantation in children.Patients with biliary atresia(BA) may have difficulty achieving satisfactory weight gain with enteral nutrition alone,and parenteral nutrition(PN) may be indicated.While PN has been shown to improve anthropometric parameters of children with BA listed for liver transplantation,less is known about the risks,particularly infectious,associated with this therapy among this specific group of patients.AIM To describe the incidence,microbiology,and risk factors of central line-associated bloodstream infection(CLABSI) among children with BA listed for liver transplantation.METHODS Retrospective review of children aged ≤ 2-years of age with BA who were listed for primary liver transplantation at Texas Children's Hospital from 2008 through2015(n = 96).Patients with a central line for administration of PN(n = 63) were identified and details of each CLABSI event were abstracted.We compared the group of patients who experienced CLABSI to the group who did not,to determine whether demographic,clinical,or laboratory factors correlated with development of CLABSI.RESULTS Nineteen of 63 patients(30%,95%CI:19,43) experienced 29 episodes of CLABSI during 4800 line days(6.04 CLABSI per 1000 line days).CLABSI was predominantly associated with Gram-negative organisms(14/29 episodes,48%)including Klebsiella spp.,Enterobacter spp.,and Escherichia coli.The sole polymicrobial infection grew Enterobacter cloacae and Klebsiella pneumoniae.Grampositive organisms(all Staphylococcus spp.) and fungus(all Candida spp.)comprised 9/29(31%) and 6/29(21%) episodes,respectively.No demographic,clinical,or laboratory factors were significantly associated with an increased risk for the first CLABSI event in Cox proportional hazards regression analysis CONCLUSION There is substantial risk for CLABSI among children with BA listed for liver transplantation.No clinical,demographic,or laboratory factor we tested emerged as an independent predictor of CLABSI.While our data did not show an impact of CLABSI on the short-term clinical outcome,it would seem prudent to implement CLABSI reduction strategies in this population to the extent that each CLABSI event represents potentially preventable hospitalization,unnecessary healthcare dollar expenditures,and may exact an opportunity cost,in terms of missed allograft offers.Nicole D Triggs Stacey Beer Sonam Mokha Kat Hosek Danielle Guffey Charles G Minard Flor M Munoz Ryan W Himes 2019World Journal of Hepatology2019,11,2:2
15On the friction and adhesion hysteresis between polymer brushes attached to curved surfaces: Rate and solvation effects显示文摘Computer simulations of friction between polymer brushes are usually simplified compared to real systems in terms of solvents and geometry.In most simulations,the solvent is only implicit with infinite compressibility and zero inertia.In addition,the model geometries are parallel walls rather than curved or rough as in reality.In this work,we study the effects of these approximations and more generally the relevance of solvation on dissipation in polymer-brush systems by comparing simulations based on different solvation schemes.We find that the rate dependence of the energy loss during the collision of brush-bearing asperities can be different for explicit and implicit solvent.Moreover,the non-Newtonian rate dependences differ noticeably between normal and transverse motion,i.e.,between head-on and off-center asperity collisions.Lastly,when the two opposing brushes are made immiscible,the friction is dramatically reduced compared to an undersaturated miscible polymer-brush system,irrespective of the sliding direction.Sissi de BEER G.DjuidjéKENMOÉ Martin H.MÜSER 2015Friction2015,3,2:2

20Impact of cardiac magnet resonance imaging on management of ventricular septal rupture after acute myocardial infarction显示文摘A 74-year-old man was admitted to the cardiac catheterization laboratory with acute myocardial infarction. After successful angioplasty and stent implantation into the right coronary artery, he developed cardiogenic shock the following day. Echocardiography showed ventricular septal rupture. Cardiac magnet resonance imaging (MRI) was performed on the critically ill patient and provided detailed information on size and localization of the ruptured septum by the use of fast MRI sequences. Moreover, the MRI revealed that the ventricular septal rupture was within the myocardial infarction area, which was substantially larger than the rupture. As the patient's condition worsened, he was intubated and had intra-aortic balloon pump implanted, and extracorporeal membrane oxygenation was initiated. During the following days, the patient's situation improved, and surgical correction of the ventricular septal defect could successfully be performed. To the best of our knowledge, this case report is the first description of postinfarction ventricular septal rupture by the use of cardiac MRI in an intensive care patient with cardiogenic shock and subsequent successful surgical repair.Tobias Gassenmaier Armin Gorski Ivan Aleksic Nikolas Deubner Frank Weidemann Meinrad Beer 2013World Journal of Cardiology2013,5,5:2
