2Challenges and prospects for consumer acceptance of cultured meat显示文摘Consumer acceptance of cultured meat is expected to depend on a wide diversity of determinants ranging from technologyrelated perceptions to product-specific expectations, and including wider contextual factors like media coverage, public involvement, and trust in science, policy and society. This paper discusses the case of cultured meat against this multitude of possible determinants shaping future consumer acceptance or rejection. The paper also presents insights from a primary exploratory study performed in April 2013 with consumers from Flanders(Belgium)(n=180). The concept of cultured meat was only known(unaided) by 13% of the study participants. After receiving basic information about what cultured meat is, participants expressed favorable expectations about the concept. Only 9% rejected the idea of trying cultured meat, while two thirds hesitated and about quarter indicated to be willing to try it. The provision of additional information about the environmental benefits of cultured meat compared to traditional meat resulted in 43% of the participants indicating to be willing to try this novel food, while another 51% indicated to be ‘maybe' willing to do so. Price and sensory expectations emerged as major obstacles. Consumers eating mostly vegetarian meals were less convinced that cultured meat might be healthy, suggesting that vegetarians may not be the ideal primary target group for this novel meat substitute. Although exploratory rather than conclusive, the findings generally underscore doubts among consumers about trying this product when it would become available, and therefore also the challenge for cultured meat to mimic traditional meat in terms of sensory quality at an affordable price in order to become acceptable for future consumers.Wim Verbeke Pierre Sans Ellen J Van Loo 2015Journal of Integrative Agriculture2015,14,2:10
3Effect of climate change on seasonal monsoon in Asia and its impact on the variability of monsoon rainfall in Southeast Asia显示文摘Global warming and climate change is one of the most extensively researched and discussed topical issues affecting the environment.Although there are enough historical evidence to support the theory that climate change is a natural phenomenon,many research scientists are widely in agreement that the increase in temperature in the 20 th century is anthropologically related.The associated effects are the variability of rainfall and cyclonic patterns that are being observed globally.In Southeast Asia the link between global warming and the seasonal atmospheric flow during the monsoon seasons shows varying degree of fuzziness.This study investigates the impact of climate change on the seasonality of monsoon Asia and its effect on the variability of monsoon rainfall in Southeast Asia.The comparison of decadal variation of precipitation and temperature anomalies before the 1970 s found general increases which were mostly varying.But beyond the 1970 s,global precipitation anomalous showed increases that almost corresponded with increases in global temperature anomalies for the same period.There are frequent changes and a shift westward of the Indian summer monsoon.Although precipitation is observed to be 70%below normal levels,in some areas the topography affects the intensity of rainfall.These shifting phenomenon of other monsoon season in the region are impacting on the variability of rainfall and the onset of monsoons in Southeast Asia and is predicted to delay for 15 days the onset of the monsoon in the future.The variability of monsoon rainfall in the SEA region is observed to be decadal and the frequency and intensity of intermittent flooding of some areas during the monsoon season have serious consequences on the human,financial,infrastructure and food security of the region.Yen Yi Loo Lawal Billa Ajit Singh 2015Geoscience Frontiers2015,6,6:8
4通过贻贝养殖改善海水水质:瑞典社会的可盈利性方案显示文摘沿海水域的富营养化是一个在全球范围内需要付出巨大社会代价的严重的环境问题。在斯卡格拉克海峡东部,富营养化的降低计划通过氮输入量的减少逐步实现,但目前还不清楚如何去减少氮的输入量。其中一个可能的方法是养殖紫贻贝等滤食性生物,这种贻贝能够在生产海产品、饲料和农业肥料的同时也能够除去氮,从而将营养盐由海洋再循环到了陆地上。在瑞典西海岸的古尔马峡湾,我们对贻贝养殖可能对氮循环产生的影响进行了模拟。结果显示,该峡湾口地区氮的净输送量(溶解氮和颗粒状氮的总和)下降了20%。现有的商业贻贝养殖场已经免费提供了这种服务,但它对社会带来的利益将会远远大于这些。我们建议,不应该向贻贝饲养人支付劳动报酬,而应引入营养交换体制以提高沿海水域的状况。在这样的背景下提出了一个通过养殖贻贝来替代在吕瑟希尔社区的污水处理厂中消减氮含量的选择方案。生体毒素的聚积已被确定为瑞典的商业贻贝养殖进一步扩大方面的最大障碍,但这一问题似乎可以通过新技术和管理战略得以解决。在现有和可能的规定和支付费用的基础上,我们提出了一些可能会实现双赢的解决方案。Odd Lindahl Rob Hart Bodil Hernroth Sven Kollberg Lars-Ove Loo Lars Olrog Ann-Sofi Rehnstam-Holm Jonny Svensson Susanne Svensson Ulf Syversen 许天虎 2005AMBIO-人类环境杂志2005,34,2:7
5Ancient migration routes of Austronesian-speaking populations in oceanic Southeast Asia and Melanesia might mimic the spread of nasopharyngeal carcinoma显示文摘Mitochondrial DNA (mtDNA) and non-recombining Y chromosome (NRY) are inherited uni-parentally from mother to daughter or from father to son respectively. Their polymorphism has initially been studied throughout populations of the world to demonstrate the 'Out of Africa' hypothesis. Here, to correlate the distribution of nasopharyngeal carcinoma (NPC) in different populations of insular Asia, we analyze the mtDNA information (lineages) obtained from genotyping of the hyper variable region (HVS I & II) among 1400 individuals from island Southeast Asia (ISEA), Taiwan and Fujian and supplemented with the analysis of relevant coding region polymorphisms. Lineages that best represented a clade (a branch of the genetic tree) in the phylogeny were further analyzed using complete genomic mtDNA sequencing. Finally, these complete mtDNA sequences were used to construct a most parsimonious tree which now constitutes the most up-to-date mtDNA dataset available on ISEA and Taiwan. This analysis has exposed new insights of the evolutionary history of insular Asia and has strong implications in assessing possible correlations with linguistic, archaeology, demography and the NPC distribution in populations within these regions. To obtain a more objective and balanced genetic point of view, slowly evolving biallelic Y single nucleotide polymorphism (Y-SNP) was also analyzed. As in the first step above, the technique was first applied to determine affinities (macro analysis) between populations of insular Asia. Secondly, sixteen Y short tandem repeats (Y-STR) were used as they allow deeper insight (micro analysis) into the relationship between individuals of a same region. Together, mtDNA and NRY allowed a better definition of the relational, demographic, cultural and genetic components that constitute the make up of the present day peoples of ISEA. Outstanding findings were obtained on the routes of migration that occurred along with the spread of NPC during the settlement of insular Asia. The results of this analysis will be discussed using a conceptual approach.Jean Trejaut Chien-Liang Lee Ju-Chen Yen Jun-Hun Loo Marie Lin 2011Chinese Journal of Cancer2011,30,2:7
6Inhalation of nanoparticle-based drug for lung cancer treatment:Advantages and challenges显示文摘Ever since the success of developing inhalable insulin,drug delivery via pulmonary administration has become an attractive route to treat chronic diseases.Pulmonary delivery system for nanotechnology is a relatively new concept especially when applicable to lung cancer therapy.Nano-based systems such as liposome,polymeric nanoparticles or micelles are strategically designed to enhance the therapeutic index of anti-cancer drugs through improvement of their bioavailability,stability and residency at targeted lung regions.Along with these benefits,nano-based systems also provide additional diagnostic advantages during lung cancer treatment,including imaging,screening and drug tracking.Nevertheless,delivery of nanobased drugs via pulmonary administration for lung cancer therapy is still in its infancy and numerous challenges are expected.Pharmacology,immunology,toxicology and largescale manufacturing(stability and activity of drugs)are some aspects in nanotechnology that should be taken into consideration for the development of inhalable nano-based chemotherapeutic drugs.This review will focus on the current inhalable nano-based drugs for lung cancer treatment.Wing-Hin Lee Ching-Yee Loo Daniela Traini Paul M.Young 2015Asian Journal of Pharmaceutical Sciences2015,10,6:6
7Garcinol sensitizes human head and neck carcinoma to cisplatin in a xenograft mouse model despite downregulation of proliferative biomarkers显示文摘OBJECTIVE Platinum compounds such as cisplatin and carboplatin are frequently used as the first-line chemotherapy for the treatment of the head and neck squamous cell carcinoma(HNSCC).In the present study,we investigated whether garcinol,apolyisoprenylated benzophenone can chemosensitize HNSCC to cisplatin.METHODS The effect of garcinol and cisplatin on HNSCC was assessed by MTT,Western blotting,real time PCR,FACS,immunohistochemistry,DNA binding assay and xenograft mouse model.RESULTS We found that garcinol inhibited the viability of a panel of diverse HNSCC cell lines,enhanced the apoptotic effect of cisplatin,suppressed constitutive as well as cisplatin-induced NF-κB activation,and downregulated the expression of various oncogenic gene products(cyclin D1,Bcl-2,survivin and VEGF).In vivo study showed that administration of garcinol alone(0.5 mg·kg-1,ip five times/week)significantly suppressed the growth of the tumor,and this effect was further increased by cisplatin.Both the markers of proliferation index(Ki-67)and microvessel density(CD31)were downregulated in tumor tissues by the combination of cisplatin and garcinol.The pharmacokinetic results of garcinol indicated that good systemic exposure was achievable after ip administration of garcinol at 0.5and 2mg·kg-1 with mean peak concentration(cmax)of 1825.4 and 6635.7nmol·L-1 in the mouse serum,respectively.CONCLUSION Overall,our results suggest that garcinol can indeed potentiate the effects of cisplatin by negative regulation of various inflammatory and proliferative biomarkers.Feng Li Muthu K.

10Investigation of physico-chemical properties and microbial community during poultry manure co-composting process显示文摘Co-composting of poultry manure and rubber wood sawdust was performed with the ratio of 2:1(V/V) for a period of 60 days. An investigation was carried out to study the extracellular enzymatic activities and structural degradation utilizing Fourier transform infrared spectroscopy(FT-IR), thermogravimetry and differential thermal analysis(TG/DTA)and scanning electron microscopy(SEM). The microbial succession was also determined by using denaturing gel gradient electrophoresis(DGGE). The compost was able to reach its highest temperature of 71°C at day 3 and stabilized between 30 and 40°C for 8 weeks.CMCase, FPase and β-glucosidase acted synergistically in order to degrade the cellulosic substrate. The xylanase activities increased gradually during the composting and reached the peak value of 11.637 U/g on day 35, followed by a sharp decline. Both Li P and Mn P activities reached their peak values on day 35 with 0.431 and 0.132 U/g respectively. The FT-IR spectra revealed an increase in aromaticity and a decrease in aliphatic compounds such as carbohydrates as decomposition proceeded. TGA/DTG data exhibited significant changes in weight loss in compost samples, indicating degradation of organic matter. SEM micrographs showed higher amounts of parenchyma exposed on the surface of rubber wood sawdust at day 60, showing significant degradation. DGGE and 16 S r DNA analyses showed that Burkholderia sp., Pandoraea sp., and Pseudomonas sp. were present throughout the composting process. Ornithinibacillus sp. and Castellaniella ginsengisoli were only found in the initial stage of the composting, while different strains of Burkholderia sp. also occurred in the later stage of composting.Omar Farah Nadia Loo Yu Xiang Lee Yei Lie Dzulkornain Chairil Anuar Mohammed P.Mohd Afandi Samsu Azhari Baharuddin 2015Journal of Environmental Sciences2015,27,2:4

12Socioecological drivers facilitating biodiversity conservation in traditional farming landscapes显示文摘Traditional farming landscapes have evolved as tightly coupled socioecological systems that support high biodiversity.However,land-use change severely threatens the high biodiversity of these landscapes.Navigating nature conservation in such landscapes requires a thorough understanding of the key drivers underpinning biodiversity.Through empirical research on mammals,birds,butterflies,and plants in a traditional cultural landscape in Romania,we revealed seven hypothesized drivers facilitating biodiversity conservation.Similar proportions of three main land-use types support the landscape species pool,most likely through habitat connectivity and frequent spillover between land-use types.Landscape complementation and supplementation provide additional habitat for species outside their core habitats.Gradients of woody vegetation cover and gradients in land-cover heterogeneity provide mosaic landscapes with wide ranges of resources.Traditional land-use practices underpin landscape heterogeneity,traditional land-use elements such as wood pastures,and human-carnivore coexistence.Top-down predator control may limit herbivore populations.Lastly,cultural ties between humans and nature have a central influence on people’s values and sustainable use of natural resources.Conservation approaches should aim to maintain or restore these socioecological drivers by targeting the heterogeneous character of the forest-farmland mosaic at large scales through'broad and shallow'conservation measures.These large-scale measures should be complemented with'deep and narrow'conservation measures addressing specific land-use types,threats,or species.In both cases,conservation measures should integrate the entire socioecological system,by recognizing and strengthening important links between people and the environment.Ine Dorresteijn Jacqueline Loos Jan Hanspach Joern Fischer 2015Ecosystem Health and Sustainability2015,1,9:3
13轴突生长抑制因子DNA疫苗对大鼠中枢神经系统的影响(英文)显示文摘目的探讨轴突生长抑制因子DNA疫苗(pcDNA-NGIs)免疫是否会对中枢神经系统造成损害。方法以pcDNA-NGIs免疫成年Sprague-Dawley大鼠,免疫期间进行实验性自动免疫性脑髓鞘炎评分,同时观察实验动物的感觉运动功能和认知行为。结果以pcDNA-NGIs免疫的大鼠未出现实验性自动免疫性脑髓鞘炎症状。复合神经病学评分、粘附纸条清除试验和开放场地试验表明,pcDNA-NGIs免疫不会损害实验动物的感觉运动功能。另外,被动回避试验和主动回避试验证明,pcDNA-NGIs免疫不会引起学习和记忆障碍。结论pcDNA-NGIs免疫不会损害实验大鼠中枢神经系统。朱兴宝 Jasmine Lee Jill Wong Wan Loo Tan 冯忠堂 肖志成 Ivan Ng 2007中华神经外科疾病研究杂志2007,6,3:3
14黄斑色素光学密度、中央黄斑厚度与体重指数的关系(英文)显示文摘目的:评估黄斑色素光学密度(MPOD)、中央黄斑厚度与体重指数(BMI)的关系。方法:这是一项在单一机构中进行比较的横断面研究。本研究共纳入210名符合入选标准的志愿者。使用黄斑色素筛选剂II对受试者MPOD进行测量。使用SD Cirrus OCT测量中央黄斑厚度。记录所有眼MPOD和OCT信息。使用Microsoft~?Excel,SPSS和R进行数据分析。结果:MPOD和中央黄斑厚度之间呈明显正相关(r=0.42,P<0.01)。同时,MPOD和BMI之间呈明显负相关(r=-0.23,P<0.01)。结论:研究得出,MPOD和中央黄斑厚度之间呈明显正相关。还需要进一步研究中央凹的详细结构及其与MPOD的关系。研究发现了MPOD与BMI之间呈明显正相关,且得出BMI的降低可能会增加黄斑色素的密度,这有助于预防年龄相关性黄斑变性(ARMD)。Lee Hong Nien Fazliana Ismail Rafidah Sudarno Angela Loo Voon Pei Visvaraja Subrayan 2019国际眼科杂志2019,19,5:3

16Poststroke DNA immunization against neurite growth inhibitors is beneficial to the recovery from local cerebral ischemia in rats显示文摘BACKGROUND: Inhibitory signals, i.e. neurite growth inhibitors (NGIs), presenting on central nervous system (CNS) myelin have been shown to play a crucial role in inhibiting lesioned axonal sprouting and leading to less functional recovery. Vaccines targeting NGIs may provide multifactorial protection against brain insults by overcoming the inhibitory effects of these NGIs and boosting the body's immune repair mechanisms. OBJECTIVE: To evaluate the effect of poststroke DNA immunization against NGIs on the rehabilitation for sensorimotor function of rat models of local cerebral ischemia. DESIGN: Completely randomized grouping design, and controlled experiment. SETTING: Brain Injury Research Laboratory, Department of Neurosurgery, National Neuroscience Institute, Singapore. MATERIALS: Sixty adult male Sprague-Dawley rats ranging in age from 45 to 120 days and in weight from 180 to 250 grams were provided by Animal Center of Department of Anatomy, Faculty of Medicine, National University of Singapore. pcDNA3.1(+)-neurite growth inhibitors (pcDNA-NGIs) a gift was provided by Dr. Xiao from Department of Clinical Research, Singapore General Hospital, Singapore. METHODS: The experiment was carried out at Brain Injury Research Laboratory, Department of Neurosurgery, National Neuroscience Institute, Singapore from August 2003 to April 2005. ①The involved rats were randomized into 3 groups: pcDNA-NGIs group (group A), pcDNA3.1 (+) group (group B) and model group (group C), with 20 rats in each group. Left focal cerebral ischemia (FCI) was permanently induced through middle cerebral artery occlusion (MCAO) with the assistance of an operating microscope. Successful MCAO was determined by a 20% decrease to baseline in the ipsilateral cerebral blood flow. 100 μg of pcDNA-NGIs eluted in phosphate-buffered saline (PBS) was intramuscularly injected into the tibial muscle once a week after MCAO for 6 weeks in group A. As control, pcDNA3.1 (+) was also administrated in the same way in group B and nothing was administrated in group C. ② The modified neurological severity score (mNSS), a composite of motor, sensory, reflex and balance tests, was used to test the sensorimotor deficit. The mNSS was graded on a scale of 0–18, i.e. normal score was 0, maximal deficit score was 18, and 1 point was warded for the inability to perform the tasks or the lack of a tested reflex. ③ The newly generated axons of corticorubral projection were traced by stereotaxic guided injection of 100 g/L biotinylated dextran amine. Rats were sacrificed two weeks after tracing, and cryostat coronal sections of midbrains (30 μm) were reacted to BDA according to the manufacturer's instruction by the free-floating method. Images were captured on a DM RXA2 LEICA Microscope with a Spot Digital Camera system (Germany), and the numbers of labeled axons on the denervated side in four standard coronal sections including the red nucleus were manually quantified. MAIN OUTCOME MEASURES: ① The number of newly generated axons of corticorubral projection. ②The improvement in sensorimotor deficit. RESULTS: All the involved 60 rats entered the stage of final analysis. ① The number of newly generated axons of corticorubral projection of rats: Only ipsilateral axons of CRP were noted with little evidence of fibers crossing to the contralateral red nucleus in rats of groups B and C. More BDA-positive fibers crossing the midline and terminating in the contralateral red nucleus in appropriate target areas mirroring thenon-differentiated red nucleus were found in rats of group A. Quantitative analysis showed that BDA-labeled axons in the denervated side of rats in group A were more than those in group B (P < 0.05). ② Improvement in sensorimotor deficit of rats: At 2 weeks after immunization, significant improvement in sensorimotor deficit was found in rats of group A. There were significant differences of improvement in sensorimotor deficit of rats between group A and group B or group C at 12 and 14 weeks after immunization (P < 0.05). CONCLUSION: ① Poststroke DNA immunization against NGIs leads to increased sensorimotor recovery following FCI and compensatory newly growth of axons from corticorubral projection.Xingbao Zhu Jasmine Lee Jill Wong Wan Loo Tan Zhongtang Feng Tinghua Wang Zhicheng Xiao Ivan Ng 2007Neural Regeneration Research2007,2,2:3
17扁桃体鳞癌中HPV感染与EGFR、VEGF表达的相关性研究显示文摘目的:研究扁桃体鳞癌(squamous cell carcinomas of the tonsil tonsillar,SCCs)中人乳头瘤病毒(human papillomavirus,HPV)感染与血管内皮生长因子(vascular endothelial growth factor,VEGF)和表皮生长因子受体(epidermal growth factor,EGFR)表达的关系,探讨HPV与EGFR和VEGF在扁桃体鳞癌发生中的交互效应。方法:采用多重实时荧光定量聚合酶链反应(multiplex real-time polymerase chain reaction,MT-PCR)检测85例扁桃体鳞癌HPV DNA及型别,通过HPV DNA分析进行HPV感染状况的测定;同时采用半定量免疫组化检测HPV(+)组和HPV(-)组中VEGF、EGFR蛋白表达情况。结果:扁桃体鳞癌中HPV感染率为49.4%(42/85),HPV-16型占所有感染者的比例为90.5%(38/42),明显高于其他型别;HPV(+)组EGFR蛋白表达明显低于HPV(-)组(P值均<0.01);HPV(+)组与HPV(-)组VEGF蛋白表达无明显差异;此外,VEGF表达与EGFR、患者的年龄、性别、TNM分期、组织学分级均无明显相关性。结论:HPV感染与扁桃体鳞癌的发生存在相关性,HPV相关的扁桃体鳞癌中,HPV基因可能通过改变EGFR表达致癌,为HPV致癌机理进一步研究提供一个新的视角,具有重要的理论意义。费继敏 Timothy A Dobbins Deanna Jones C Soon Lee Christine Loo Jonathan Clark Barbara Rose 2015现代肿瘤医学2015,23,4:3
18Senescent human hepatocytes express a unique secretory phenotype and promote macrophage migration显示文摘AIM:To develop a model of stress-induced senescence to study the hepatocyte senescence associated secretory phenotype(SASP).METHODS:Hydrogen peroxide treatment was used to induce senescence in the human Hep G2 hepatocyte cell line.Senescence was confirmed by cytochemical staining for a panel of markers including Ki67,p21,heterochromatin protein 1β,and senescence-associated-β-galactosidase activity.Senescent hepatocytes were characterised by gene expression arrays and quantitative polymerase chain reaction(q PCR),and conditioned media was used in proteomic analyses,a human chemokine protein array,and cell migration assays to characterise the composition and function of the hepatocyte SASP.RESULTS:Senescent hepatocytes induced classical markers of senescence(p21,heterochromatin protein1β,and senescence-associated-β-galactosidase activity);and downregulated the proliferation marker,Ki67.Hepatocyte senescence induced a 4.6-fold increase in total secreted protein(P=0.06)without major alterations in the protein profile.Senescence-induced genes were identified by microarray(Benjamini Hochbergcorrected P<0.05);and,consistent with the increase in secreted protein,gene ontology analysis revealed a significant enrichment of secreted proteins among inducible genes.The hepatocyte SASP included characteristic factors such as interleukin(IL)-8 and IL-6,as well as novel components such as SAA4,IL-32and Fibrinogen,which were validated by q PCR and/or chemokine protein array.Senescent hepatocyteconditioned medium elicited migration of inflammatory(granulocyte-macrophage colony stimulating factor,GM-CSF-derived),but not non-inflammatory(CSF-1-derived)human macrophages(P=0.022),which could contribute to a pro-inflammatory microenvironment in vivo,or facilitate the clearance of senescent cells.CONCLUSION:Our novel model of hepatocyte senescence provides insights into mechanisms by which senescent hepatocytes may promote chronic liver disease pathogenesis.Katharine M Irvine Richard Skoien Nilesh J Bokil Michelle Melino Gethin P Thomas Dorothy Loo Brian Gabrielli Michelle M Hill Matthew J Sweet Andrew D Clouston Elizabeth E Powell 2014World Journal of Gastroenterology2014,20,47:2
