| 1 | Identification of CD13,CD107a,and CD164 as novel basophil-activation markers and dissection of two response patterns in time kinetics of IgE-de-pendent upregulation显示文摘Using two-colour flow cytometry >200 antibodies submitted to the 8th International Workshop of Human Leukocyte Differentiation Antigens (HLDA8) have been analyzed for their reactivity with resting and activated CD203c+ basophils. Four antibodies either non-reactive or weakly reactive with resting basophils exhibited an increased reactivity with basophils activated by anti-IgE-mediated cross-linking of the high affinity IgE receptor (FcεRI). These include antibod- ies against CD164 (WS-80160, clone N6B6 and WS-80162, clone 67D2), as well as two reagents with previously unknown specificities that were identified as CD13 (WS-80274, clone A8) and CD107a (WS-80280, clone E63-880). The activation patterns followed either the “CD203c-like” or “CD63-like” activation profile. The CD203c profile is characterized by a rapid and significant upregulation (of CD13, CD164, and CD203c), reaching maximum levels after 5- 15 min of stimulation. The phosphoinositide-3-kinase (PI3K)-specific inhibitor wortmannin inhibited the upregulation of these markers whereas 12-O-tetradecanoyl-phorbol-13-acetate (TPA) induced a rapid and FcεRI-independent upregulation within 1-2 min. In the CD63 profile, maximum upregulation (of CD63 and CD107a) was detected only after 20-40 min, and upregulation by TPA reached maximum levels after 60 min. In summary, our data identify CD13, CD107a, and CD164 as novel basophil-activation antigens. Based on time kinetics of upregulation, we hypothesize that molecules of the “CD203c group” and the “CD63 group” are linked to two different mechanisms of basophil activation. | Florian HENNERSDORF Stefan FLORIAN Andreas JAKOB Katharina BAUMGRTNER Karoline SONNECK Alfred NORDHEIM Tilo BIEDERMANN Peter VALENT Hans-Jrg BüHRING | 2005 | Cell Research2005，15，5： | 9 |
| 2 | Risk factors for Barrett’s oesophagus and oesophageal adenocarcinoma:Results from the FINBAR study显示文摘AIM:To investigate risk factors associated with Barrett's oesophagus and oesophageal adenocarcinoma.METHODS:This all-Ireland population-based case-control study recruited 224 Barrett's oesophagus patients,227 oesophageal adenocarcinoma patients and 260 controls.All participants underwent a structured interview with information obtained about potential lifestyle and environmental risk factors.RESULTS:Gastro-oesophageal reflux was associated with Barrett's [OR 12.0(95% CI 7.64-18.7)] and oesophageal adenocarcinoma [OR 3.48(95% CI 2.25-5.41)].Oesophageal adenocarcinoma patients were more likely than controls to be ex-or current smokers [OR 1.72(95% CI 1.06-2.81)and OR 4.84(95% CI 2.72-8.61)respectively] and to have a high body mass index [OR 2.69(95% CI 1.62-4.46)].No significant associations were observed between these risk factors and Barrett's oesophagus.Fruit but not vegetables were negatively associated with oesophageal adenocarcinoma [OR 0.50(95% CI 0.30-0.86)].CONCLUSION:A high body mass index,a diet low in fruit and cigarette smoking may be involved in the progression from Barrett's oesophagus to oesophageal adenocarcinoma. | Lesley A Anderson RG Peter Watson Seamus J Murphy Brian T Johnston Harry Comber Jim Mc Guigan John V Reynolds Liam J Murray | 2007 | World Journal of Gastroenterology2007，13，10： | 5 |
| 3 | Comparison of novel and standard diagnostic tools for the detection of Schistosoma mekongi infection in Lao People’s Democratic Republic and Cambodia显示文摘Background:Given the restricted distribution of Schistosoma mekongi in one province in Lao People’s Democratic Republic(Lao PDR)and two provinces in Cambodia,together with progress of the national control programmes aimed at reducing morbidity and infection prevalence,the elimination of schistosomiasis mekongi seems feasible.However,sensitive diagnostic tools will be required to determine whether elimination has been achieved.We compared several standard and novel diagnostic tools in S.mekongi-endemic areas.Methods:The prevalence and infection intensity of S.mekongi were evaluated in 377 study participants from four villages in the endemic areas in Lao PDR and Cambodia using Kato-Katz stool examination,antibody detection based on an enzyme-linked immunosorbent assay(ELISA)and schistosome circulating antigen detection by lateral-flow tests.Two highly sensitive test systems for the detection of cathodic and anodic circulating antigens(CCA,CAA)in urine and serum were utilized.Results:Stool microscopy revealed an overall prevalence of S.mekongi of 6.4%(one case in Cambodia and 23 cases in Lao PDR),while that of Opisthorchis viverrini,hookworm,Trichuris trichiura,Ascaris lumbricoides and Taenia spp.were 50.4%,28.1%,3.5%,0.3%and 1.9%,respectively.In the urine samples,the tests for CCA and CAA detected S.mekongi infections in 21.0%and 38.7%of the study participants,respectively.In the serum samples,the CAA assay revealed a prevalence of 32.4%,while a combination of the CAA assay in serum and in urine revealed a prevalence of 43.2%.There was a difference between the two study locations with a higher prevalence reached in the samples from Lao PDR.Conclusions:The CCA,CAA and ELISA results showed substantially higher prevalence estimates for S.mekongi compared to Kato-Katz thick smears.Active schistosomiasis mekongi in Lao PDR and Cambodia might thus have been considerably underestimated previously.Hence,sustained control efforts are still needed to break transmission of S.mekongi.The pivotal role of highly sensitive diagnostic assays in areas targeting elimination cannot be overemphasised. | Youthanavanh Vonghachack Somphou Sayasone Virak Khieu Robert Bergquist Govert Jvan Dam Pytsje THoekstra Paul L.A.M.Corstjens Beatrice Nickel Hanspeter Marti Jürg Utzinger Sinuon Muth Peter Odermatt | 2017 | Infectious Diseases of Poverty2017，6，1： | 4 |
| 4 | Have patients with esophagitis got an increased risk of adenocarcinoma? Results from a population-based study显示文摘AIM: To examine an increased risk of esophageal adenocarcinoma is restricted to patients who develop Barrett's esophagus or whether esophagitis per se is a risk factor for adenocarcinoma.METHODS: A population-based cohort of patients with histological evidence of esophagitis without Barrett's esophagus was constructed using electronic pathology reports relating to all esophageal biopsies in Northern Ireland between 1993 and 1996. Person-years of followup and incident cases of esophageal cancer were calculated by linking the cohort to death files and the Northern Ireland Cancer Registry records. Standardized incidence ratios (SIR) were calculated for esophageal cancers (adenocarcinoma, squamous cell carcinoma (SCC), and histologically unspecified cancers).RESULTS: A total of 2 013 patients in the cohort provided 13 559 patient-years of follow-up (mean follow-up 6.7 years). None of the patients developed adenocarcinoma. Three patients developed SCC, and six developed histologically unspecified cancers. The SIR for all esophageal cancers and for SCC were 2.73 (95%CI 1.25-5.19) and 2.93 (95%CI 0.61-8.59), respectively. In a sensitivity analysis in which all unspecified esophageal cancers were treated as adenocarcinomas, the SIR for adenocarcinoma was 2.64 (0.97-5.75).CONCLUSION: The risk of adenocarcinoma is not elevated in patients with histological evidence of esophagitis without Barrett's esophagus; however, these patients may have a moderately increased risk of SCC.Further studies are required to confirm these findings,which suggest that Barrett's esophagus, not esophagitis,is the key precursor lesion in the development of adenocarcinoma. | Seamus J Murphy Lesley A Anderson Brian T Johnston Deirdre A Fitzpatrick Peter RG Watson Pauline Monaghan Liam J Murray | 2005 | World Journal of Gastroenterology2005，11，46： | 4 |
| 5 | Development of ^(18)F-labeled radiotracers for neuroreceptor imaging with positron emission tomography显示文摘Positron emission tomography(PET)is an in vivo molecular imaging tool which is widely used in nuclear medicine for early diagnosis and treatment follow-up of many brain diseases.PET uses biomolecules as probes which are labeled with radionuclides of short half-lives,synthesized prior to the imaging studies.These probes are called radiotracers.Fluorine-18 is a radionuclide routinely used in the radiolabeling of neuroreceptor ligands for PET because of its favorable half-life of 109.8 min.The delivery of such radiotracers into the brain provides images of transport,metabolic,and neurotransmission processes on the molecular level.After a short introduction into the principles of PET,this review mainly focuses on the strategy of radiotracer development bridging from basic science to biomedical application.Successful radiotracer design as described here provides molecular probes which not only are useful for imaging of human brain diseases,but also allow molecular neuroreceptor imaging studies in various small-animal models of disease,including geneticallyengineered animals.Furthermore,they provide a powerful tool for in vivo pharmacology during the process of pre-clinical drug development to identify new drug targets,to investigate pathophysiology,to discover potential drug candidates,and to evaluate the pharmacokinetics and pharmacodynamics of drugs in vivo. | Peter Brust Jrg van den Hoff Jrg Steinbach | 2014 | Neuroscience Bulletin2014，30，5： | 3 |
| 6 | National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales. | Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser | 2021 | Forest Ecosystems2021，8，1： | 2 |

| 10 | 新的^(99m)Tc标记σ受体肿瘤显像剂显示文摘采用整体法设计合成了新的99mTc标记的配合物[N-[2-((2-oxo-2-(4-(3-phenylpropyl)piperazin-1-yl)ethyl)(2-mercaptoethyl)amino)acetyl]-2-aminoethanethiolato]technetium(Ⅴ)oxide(PPPE-MAMA′-99mTcO)([99mTc]-2)及其相应的铼配合物(PPPE-MAMA′-ReO)(Re-2).竞争结合实验表明Re-2对σ1和σ2受体有中等亲和力,Ki值分别为8.67±0.07和5.71±1.88μmol/L;荷MCF-7人乳癌裸鼠尾静脉注射[99mTc]-2后0.5h,4h,20h采集平面图像,20h时可以看到肿瘤部位有放射性浓集,共同注射[99mTc]-2和抑制剂氟哌啶醇(1mg/kg)后显像,20h时肿瘤部位无明显放射性浓集;体内生物分布结果显示,注射后24h肿瘤中的放射性摄取为0.14%±0.01%ID/g,肿瘤/肌肉比为6.02±0.87.上述结果表明:虽然用整体设计法对前体化合物的结构进行了较大修饰,但得到的99mTc-配合物([99mTc]-2)在肿瘤内仍有一定的浓集,与σ1和σ2受体仍保持一定的亲和力.在此配合物的基础上,对其进行进一步的结构修饰有可能得到对σ受体亲和力更高的肿瘤显像剂. | 樊彩云 贾红梅 Deuther-Conrad Winnie Brust Peter Steinbach Jrg 刘伯里 | 2005 | 中国科学(B辑)2005，35，6： | 1 |
