2Imaging of gastroenteropancreatic neuroendocrine tumors显示文摘Imaging of gastroenteropancreatic neuroendocrine tumors can be broadly divided into anatomic and functional techniques.Anatomic imaging determines the local extent of the primary lesion,providing crucial information required for surgical planning.Functional imaging,not only determines the extent of metastatic disease spread,but also provides important information with regard to the biologic behavior of the tumor,allowing clinicians to decide on the most appropriate forms of treatment.We review the current literature on this subject,with emphasis on the strengths of each imaging modality.Eik Hock Tan Cher Heng Tan 2011World Journal of Clinical Oncology2011,2,1:20
3Probiotics for gastrointestinal disorders: Proposed recommendations for children of the Asia-Pacific region显示文摘Recommendations for probiotics are available in several regions. This paper proposes recommendations for probiotics in pediatric gastrointestinal diseases in the Asia-Pacific region. Epidemiology and clinical patterns of intestinal diseases in Asia-Pacific countries were discussed. Evidence-based recommendations and randomized controlled trials in the region were revised. Cultural aspects,health management issues and economic factors were also considered. Final recommendations were approved by applying the Likert scale and rated using the GRADE system. Saccharomyces boulardii CNCM I-745(Sb) and Lactobacillus rhamnosus GG(LGG) were strongly recommended as adjunct treatment to oral rehydration therapy for gastroenteritis. Lactobacillus reuteri could also be considered. Probiotics may be considered for prevention of(with the indicated strains): antibiotic-associated diarrhea(LGG or Sb); Clostridium difficile-induced diarrhea(Sb); nosocomial diarrhea(LGG); infantile colic(L reuteri) and as adjunct treatment of Helicobacter pylori(Sb and others). Specific probiotics with a history of safe use in preterm and term infants may be considered in infants for prevention of necrotizing enterocolitis. There is insufficient evidence for recommendations in other conditions. Despite a diversity of epidemiological,socioeconomical and health system conditions,similar recommendations apply well to Asia pacific countries. These need to be validated with local randomized-controlled trials.Donald Cameron Quak Seng Hock Musal Kadim Neelam Mohan Eell Ryoo Bhupinder Sandhu Yuichiro Yamashiro Chen Jie Hans Hoekstra Alfredo Guarino 2017World Journal of Gastroenterology2017,23,45:14
4Exploring new frontiers in molecular imaging:Emergence of ^(68)Ga PET/CT显示文摘Since US Food and Drug Administration approval of 18-fluorodeoxyglucose as a positron tracer,and the development of hybrid positron emission tomography/ computed tomography machines,there has been a great increase in clinical application and progress in the field of nuclear molecular imaging.However,not under- estimating the value of 18F,there are known limitations in the use of this cyclotron-produced positron tracer.We hence turn our focus to an emerging positron tracer, 68 Ga,and examine the advantages,current clinical uses and potential future applications of this radioisotope.Eik Hock Tan Soon Whatt Goh 2010World Journal of Radiology2010,2,2:12
5Poor performance of the modified early warning score for predicting mortality in critically ill patients presenting to an emergency department显示文摘BACKGROUND:This study was undertaken to validate the use of the modified early warning score(MEWS) as a predictor of patient mortality and intensive care unit(ICU)/ high dependency(HD)admission in an Asian population.METHODS:The MEWS was applied to a retrospective cohort of 1 024 critically ill patients presenting to a large Asian tertiary emergency department(ED) between November 2006 and December2007.Individual MEWS was calculated based on vital signs parameters on arrival at ED.Outcomes of mortality and ICU/HD admission were obtained from hospital records.The ability of the composite MEWS and its individual components to predict mortality within 30 days from ED visit was assessed.Sensitivity,specificity,positive and negative predictive values were derived and compared with values from other cohorts.A MEWS of ≥4 was chosen as the cut-off value for poor prognosis based on previous studies.RESULTS:A total of 311(30.4%) critically ill patients were presented with a MEWS ≥4.Their mean age was 61.4 years(SD 18.1) with a male to female ratio of 1.10.Of the 311 patients,53(17%)died within 30 days,64(20.6%) were admitted to ICU and 86(27.7%) were admitted to HD.The area under the receiver operating characteristic curve was 0.71 with a sensitivity of 53.0%and a specificity of 72.1%in addition to a positive predictive value(PPV) of 17.0%and a negative predictive value(NPV)of 93.4%(MEWS cut-off of ≥4) for predicting mortality.CONCLUSION:The composite MEWS did not perform well in predicting poor patient outcomes for critically ill patients presenting to an ED.Le Onn Ho Huihua Li Nur Shahidah Zhi Xiong Koh Papia Sultana Marcus Eng Hock Ong 2013World Journal of Emergency Medicine2013,4,4:12

7Panaxdiol Saponins Component Promotes Hematopoiesis and Modulates T Lymphocyte Dysregulation in Aplastic Anemia Model Mice显示文摘Objective: To investigate the potential efficacy of panaxadiol saponins component(PDS-C) in the treatment of aplastic anemia(AA) model mice. Methods: Totally 70 mice were divided into 7 groups as follows: normal, model, low-, medium-, high-dose PDS-C(20, 40, 80 mg/kg, namely L-, M-, H-PDS-C), cyclosporine(40 mg/kg), and andriol(25 mg/kg) groups, respectively. An immune-mediated AA mouse model was established in BALB/c mice by exposing to 5.0 Gy total body irradiation at 1.0 Gy/min, and injecting with lymphocytes from DBA mice. On day 4 after establishment of AA model, all drugs were intragastrically administered daily for 15 days, respectively, while the mice in the normal and model groups were administered with saline solution. After treatment, the peripheral blood counts, bone marrow pathological examination, colony forming assay of bone marrow culture, T lymphocyte subpopulation analysis, as well as T-bet, GATA-3 and Fox P3 proteins were detected by flow cytometry and Western blot. Results: The peripheral blood of white blood cell(WBC), platelet, neutrophil counts and hemoglobin(Hb) concentration were significantly decreased in the model group compared with the normal group(all P<0.01). In response to 3 dose PDS-C treatment, the WBC, platelet, neutrophil counts were significantly increased at a dose-dependent manner compared with the model group(all P<0.01). The myelosuppression status of AA was significantly reduced in M-, H-PDS-C groups, and hematopoietic cell quantity of bone marrow was more abundant than the model group. The colony numbers of myeloid, erythroid and megakaryocytic progenitor cells in the model group were less than those of the normal mice in bone marrow culture, while, PDS-C therapy enhanced proliferation of hematopoietic progenitor cells by significantly increasing colony numbers(all P<0.01). Furthermore,PDS-C therapy increased peripheral blood CD3^+ and CD3^+CD4^+ cells and reduced CD3^+CD8^+ cells(P<0.05 or P<0.01). Meanwhile, PDS-C treatment at medium-and high doses groups also increased CD4^+CD25^+Fox P3^+ cells, downregulated T-bet protein expression, and upregulated GATA-3 and Fox P3 protein expressions in spleen cells(P<0.05). Conclusion: PDS-C possesses dual activities, promoting proliferation hematopoietic progenitor cells and modulating T lymphocyte immune functions in the treatment of AA model mice.ZHENG Zhi-yin YU Xiao-ling DAI Tie-ying YIN Li-ming ZHAO Yan-na XU Min ZHUANG Hai-feng Chong Beng Hock GAO Rui-lan 2019Chinese Journal of Integrative Medicine2019,25,12:9
8The Future of Gas to Liquids as a Gas Monetisation Option显示文摘The paper introduces gas to liquids (GTL) as a monetising option from a technology, marketing and project perspective. GTL is complementary to LNG and pipelines. At the same time, using natural gas as a source for fuels in the form of GTL helps countries around the world to diversify their energy supplies. Furthermore, gas-based products are inherently cleaner than oil products. Shell's proprietary GTL technology or SMDS (Shell Middle Distillates Synthesis), is discussed in some detail. The paper also covers the challenges for successful implementation of GTL projects and why Shell is well positioned to take a lead in the industry on the basis of its long standing and broad experience in GTL research,plant operations, marketing and excellent track record in mega projects in the last thirty years. Shell's commitment to GTL is best demonstrated by the recent signing of a Heads of Agreement with Qatar Petroleum for the construction of the world's largest GTL plant. A key success factor is Shell's experience with marketing quantities of high quality GTL products from its 12,500 barrels per day plant at Bintulu,Malaysia since 1993. Further marketing opportunities will arise when new GTL capacity comes on-stream in the middle east when more quantities will become available to bulk users. Amongst the most interesting fuel beyond oil' providing energy security to host countries. Shell is actively engaging with a number of regulators, automotive companies and governments worldwide including China, to demonstrate the performance of GTL and its cost effectiveness in reducing local emissions. An added benefit is that GTL can use existing infrastructure and requires no investment. Finally, the paper briefly discusses the coal to liquids (CTL) process as an alternative route to produce high quality GTL products and the key issues relating to the process.Hock Cheng Heng Suhaili Idrus 2004Journal of Natural Gas Chemistry2004,13,2:8

11Recurrent giant fibrovascular polyp of the esophagus显示文摘Giant fibrovascular polyps of the esophagus and hypopharynx are rare benign esophageal tumors. They arise most commonly in the upper esophagus and may, rarely, originate in the hypopharynx. They can vary significantly in size. Even though they are benign, they may be lethal due to either bleeding or, rarely, asphyxiation if a large polyp is regurgitated. Patients commonly present with dysphagia or hematemesis. The polyps may not be well visualized on endoscopy and imaging plays a vital role in aiding diagnosis as well as providing important information for preoperative planning, such as the location of the pedicle, the vascularity of the polyp and the tissue elements of the mass. They can also be recurrent in rare cases, especially if the resection margins of the base are involved. We review the recent literature and report a case of a 61-year-old man with a recurrent giant esophageal fibrovascular polyp with illustrative contrast barium swallow, CT and intra-operative images, who required several surgeries via a combination of endoscopic, trans-oral, trans-cervical, trans-thoracic and trans-abdominal approaches.Ser Yee Lee Weng Hoong Chan Ranjiv Sivanandan Dennis Teck Hock Lim Wai Keong Wong 2009World Journal of Gastroenterology2009,15,29:7
12Liquid biopsies for liquid tumors: emerging potential of circulating free nucleic acid evaluation for the management of hematologic malignancies显示文摘Circulating free nucleic acids; cell free DNA and circulating micro-RNA, are found in the plasma of patients with hematologic and solid malignancies at levels higher than that of healthy individuals. In patients with hematologic malignancy cell free DNA reflects the underlying tumor mutational profile, whilst micro-RNAs reflect genetic interference mechanisms within a tumor and potentially the surrounding microenvironment and immune effector cells. These circulating nucleic acids offer a potentially simple, non-invasive, repeatable analysis that can aid in diagnosis, prognosis and therapeutic decisions in cancer treatment.Jay Hocking Sridurga Mithraprabhu Anna Kalff Andrew Spencer 2016Cancer Biology & Medicine2016,13,2:7

14Prehospital system delay in patients with ST-segment elevation myocardial infarction in Singapore显示文摘BACKGROUND: Timely reperfusion in ST-segment elevation myocardial infarction(STEMI)improves outcomes. System delay is that between first medical contact and reperfusion therapy,comprising prehospital and hospital components. This study aimed to characterize prehospital system delay in Singapore.METHODS: A retrospective chart review was performed for 462 consecutive STEMI patients presenting to a tertiary hospital from December 2006 to April 2008. Patients with cardiac arrest secondarily presented were excluded. For those who received emergency medical services(EMS),ambulance records were reviewed. Time intervals in the hospital were collected prospectively. The patients were divided into two equal groups of high/low prehospital system delay using visual binning technique.RESULTS: Of 462 patients, 76 received EMS and 52 of the 76 patients were analyzed. The median system delay was 125.5 minutes and the median prehospital system delay was 33.5minutes(interquartile range [IQR]=27.0, 42.0). Delay between call-received-by-ambulance and ambulance-dispatched was 2.48 minutes(IQR=1.47, 16.55); between ambulance-dispatch and arrival-at-patient-location was 8.07 minutes(IQR=1.30, 22.13); between arrival-at- and departurefrom-patient-location was 13.12 minutes(IQR=3.12, 32.2); and between leaving-patient-location to ED-registration was 9.90 minutes(IQR=1.62, 32.92). Comparing patients with prehospital system delay of less than 35.5 minutes versus more showed that the median delay between ambulancedispatch and arrival-at-patient-location was shorter(5.75 vs. 9.37 minutes, P<0.01). The median delay between arrival-at-patient-location and leaving-patient-location was also shorter(10.78 vs.14.37 minutes, P<0.01).CONCLUSION: Prehospital system delay in our patients was suboptimal. This is the first attempt at characterizing prehospital system delay in Singapore and forms the basis for improving efficiency of STEMI care.Andrew Fu Wah Ho Pin Pin Pek Stephanie Fook-Chong Ting Hway Wong Yih Yng Ng Aaron Sung Lung Wong Marcus Eng Hock Ong 2015World Journal of Emergency Medicine2015,6,4:6
15Face Masks in the New COVID-19 Normal: Materials, Testing,and Perspectives显示文摘The increasing prevalence of infectious diseases in recent decades has posed a serious threat to public health.Routes of transmission differ,but the respiratory droplet or airborne route has the greatest potential to disrupt social intercourse,while being amenable to prevention by the humble facemask.Different types of masks give different levels of protection to the user.The ongoing COVID-19 pandemic has even resulted in a global shortage of face masks and the raw materials that go into them,driving individuals to self-produce masks from household items.At the same time,research has been accelerated towards improving the quality and performance of face masks,e.g.,by introducing properties such as antimicrobial activity and superhydrophobicity.This review will cover mask-wearing from the public health perspective,the technical details of commercial and home-made masks,and recent advances in mask engineering,disinfection,and materials and discuss the sustainability of mask-wearing and mask production into the future.Ming Hui Chua Weiren Cheng Shermin Simin Goh Junhua Kong Bing Li Jason Y.CLim Lu Mao Suxi Wang Kun Xue Le Yang Enyi Ye Kangyi Zhang Wun Chet Davy Cheong Beng Hoon Tan Zibiao Li Ban Hock Tan Xian Jun Loh 2020Research2020,,1:5
16Use of Farmers’ Indicators to Evaluate the Sustainability of Cropping Systems on Sloping Land in Yunnan Province, China显示文摘Diversity in the biophysical and socio-economic attributes of agricultural systems makes them uniquely niche based. Farmers are expert in local biophysical and socio-economic situations and can contribute in developing pragmatic indicators of agro-environmental development. During evaluation of an agricultural research project in Yunnan, China, local farmers were capable of evaluating the effects of modified technologies on existing cropping systems and discussed their attitudes to the interventions using their own indicators. Farmers’ response can be grouped into seven major aspects: i) effects on income, ii) effects on production resources, iii) effects on crop management, iv) existing local knowledge about the technology, v) availability of inputs, vi) access to information, and vii) socio-economic conditions of farming households. Farmers concluded that environmental conditions in the experimental catchment in comparison to an adjacent untreated catchment were better in terms of soil and water losses, vegetation cover and natural resources, infrastructures and catchment management, use of environmentally-friendly technologies, and crop productivity. Success in soil and water conservation programmes depends on the efforts of the farmers and other local users and their greater involvement helps to identify more pragmatic indicators. Furthermore, it increases ownership of the programme, enhances interactions with the project scientists, increases farmers’ awareness of agro-environmental problems and their possible consequences. These development will enable scientists to develop better targeted interventions and increase the likelihood of adoption of tested technologies by local communities. The use of paired adjacent catchments improved evaluation activities and is proposed as good practice for future catchment improvement programmes.M. SUBEDI T. J. HOCKING M. A. FULLEN A, R. McCREA E.

19Serous pancreatic neoplasia, data and review显示文摘AIM To describe the imaging features of serous neoplasms of the pancreas using ultrasound, endoscopic ultrasound, computed tomography and magnetic resonance imaging.METHODS This multicenter international collaboration enhances a literature review to date, reporting features of 287 histologically confirmed cases of serous pancreatic cystic neoplasms(SPN). RESULTS Female predominance is seen with most SPN presenting asymptomatically in the 5th through 7th decade. Mean lesion size was 38.7 mm, 98% were single, 44.2% cystic, 46% mixed cystic and solid, and 94% hypoechoic on B-mode ultrasound. Vascular patterns and contrast-enhancement profiles are described as hypervascular and hyperenhancing.CONCLUSION The described ultrasound features can aid differentiation of SPN from other neoplastic lesions under most circumstances.Christoph F Dietrich Yi Dong Christian Jenssen Valentina Ciaravino Michael Hocke Wen-Ping Wang Eike Burmester Kathleen Moeller Nathan SS Atkinson Paola Capelli Mirko D’Onofrio 2017World Journal of Gastroenterology2017,23,30:3
20Review of Fresnel incoherent correlation holography with linear and non-linear correlations显示文摘Fresnel incoherent correlation holography(FINCH)is a well-established incoherent imaging technique.In FINCH,three selfinterference holograms are recorded with calculated phase differences between the two interfering,differently modulated object waves and projected into a complex hologram.The object is reconstructed without the twin image and bias terms by a numerical Fresnel back propagation of the complex hologram.A modified approach to implement FINCH by a single camera shot by pre-calibrating the system involving recording of the point spread function library and reconstruction by a nonlinear cross correlation has been introduced recently.The expression of the imaging characteristics from the modulation functions in original FINCH and the modified approach by pre-calibration in spatial and polarization multiplexing schemes are reviewed.The study reveals that a reconstructing function completely independent of the function of the phase mask is required for the faithful expression of the characteristics of the modulating function in image reconstruction.In the polarization multiplexing method by non-linear cross correlation,a partial expression was observed,while in the spatial multiplexing method by non-linear cross correlation,the imaging characteristics converged towards a uniform behavior.Vijayakumar Anand Tomas Katkus Soon Hock Ng Saulius Juodkazis 2021Chinese Optics Letters2021,19,2:3
