1A SPECTRAL METHOD FOR PANTOGRAPH-TYPE DELAY DIFFERENTIAL EQUATIONS AND ITS CONVERGENCE ANALYSIS显示文摘We propose a novel numerical approach for delay differential equations with vanishingproportional delays based on spectral methods.A Legendre-collocation method is em-ployed to obtain highly accurate numerical approximations to the exact solution.It isproved theoretically and demonstrated numerically that the proposed method convergesexponentially provided that the data in the given pantograph delay differential equationare smooth.Ishtiaq Ali Hermann Brunner 2009Journal of Computational Mathematics2009,27,2:13
2经鼻持续气道正压通气对阻塞性睡眠呼吸暂停低通气综合征患者睡眠结构近远期的影响显示文摘目的 观察经鼻持续气道正压 (nCPAP)通气对阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者睡眠结构近远期的影响。方法 17例对照者行多导睡眠图 (PSG)监测 ,对 30例经PSG诊断的OSAHS患者行nCPAP治疗 ,治疗第 1夜行PSG监测 ,连续家庭nCPAP治疗 6个月后行第 2次PSG监测 ,分析比较睡眠结构的变化。结果 OSAHS患者治疗前睡眠转换次数、1期、2期睡眠比例较对照组增加 (P <0 0 5 ) ,慢波睡眠期、快动眼 (REM )期比例较对照组低 (P <0 0 5 ) ;nCPAP治疗第 1夜睡眠转换次数、1期、2期睡眠比例较治疗前降低 (P <0 0 5 ) ,慢波睡眠期、REM期比例较治疗前升高 (P <0 0 5 ) ;nCPAP治疗 6个月后睡眠转换次数、1期、2期、慢波睡眠期比例与治疗第 1夜比较差异均无显著性 (P >0 0 5 ) ,而REM期比例较治疗第 1夜降低 (P <0 0 5 )。结论 OSAHS患者睡眠转换次数明显增多 ,1期睡眠增加而REM期睡眠减少 ,睡眠结构紊乱。nCPAP治疗第 1夜及6个月后睡眠结构得到有效纠正 ,是OSAHS长期有效的治疗方法之一。肖永龙 Frank Richter Fulk Brunner Birgid Lerche 张德平 郑培德 2004中华内科杂志2004,43,9:8

5Impact of parathyroid hormone on bone marrow-derived stem cell mobilization and migration显示文摘Parathyroid hormone(PTH) is well-known as the principal regulator of calcium homeostasis in the human body and controls bone metabolism via actions on the survival and activation of osteoblasts. The intermittent administration of PTH has been shown to stimulate bone production in mice and men and therefore PTH administration has been recently approved for the treatment of osteoporosis. Besides to its physiological role in bone remodelling PTH has been demonstrated to influence and expand the bone marrow stem cell niche where hematopoietic stem cells, capable of both self-renewal and differentiation, reside. Moreover, intermittent PTH treatment is capable to induce mobilization of progenitor cells from the bone marrow into the bloodstream. This novel function of PTH on modulating the activity of the stem cell niche in the bone marrow as well as on mobilization and regeneration of bone marrow-derived stem cells offers new therapeutic options in bone marrow and stem cell transplantation as well as in the field of ischemic disorders.Bruno C Huber Ulrich Grabmaier Stefan Brunner 2014World Journal of Stem Cells2014,6,5:4

9Molecular phenotypes of human parvovirus B19 in patients with myocarditis显示文摘AIM:To investigate molecular phenotypes of myocardial B19V-infection to determine the role of B19V in myocarditis and dilated cardiomyopathy(DCM).METHODS:Endomyocardial biopsies(EMBs) from 498 B19V-positive patients with myocarditis and DCMwere analyzed using molecular methods and functional experiments.EMBs were obtained from the University Hospitals of Greifswald and Tuebingen and additionally from 36 German cardiology centers.Control tissues were obtained at autopsy from 34 victims of accidents,crime or suicide.Identification of mononuclear cell infiltrates in EMBs was performed using immunohistological staining.Anti-B19V-IgM and anti-B19V-IgG were analyzed by enzyme-linked immunosorbent assay(ELISA).B19V viral loads were determined using in-house quantitative real-time polymerase chain reaction(PCR).For B19V-genotyping a new B19V-genotype-specific restriction fragment length polymorphism(RFLP)-PCR was established.B19V-genotyping was verified by direct DNAsequencing and sequences were aligned using BLAST and BioEdit software.B19V P6-promoter and HHV6-U94-transactivator constructs were generated for cell culture experiments.Transfection experiments were conducted using human endothelial cells 1.Luciferase reporter assays were performed to determine B19Vreplication activity.Statistical analysis and graphical representation were calculated using SPSS and Prism5 software.RESULTS:The prevalence of B19V was significantly more likely to be associated with inflammatory cardiomyopathy(iCMP) compared to uninflamed DCM(59.6% vs 35.3%)(P < 0.0001).The detection of B19V-mRNA replication intermediates proved that replication of B19V was present.RFLP-PCR assays showed that B19V-genotype 1(57.4%) and B19V-genotype 2(36.7%) were the most prevalent viral genotypes.B19V-genotype 2 was observed more frequently in EMBs with iCMP(65.0%) compared to DCM(35%)(P = 0.049).Although there was no significant difference in gender-specific B19V-loads,women were more frequently infected with B19V-genotype 2(44.6%) than men(36.0%)(P = 0.0448).Coinfection with B19V and other cardiotropic viruses was found in 19.2% of tissuesamples and was associated with higher B19V viral load compared to B19V-monoinfected tissue(P = 0.0012).The most frequent coinfecting virus was human herpes virus 6(HHV6,16.5%).B19V-coinfection with HHV6 showed higher B19V-loads compared to B19V-monoinfected EMBs(P = 0.0033),suggesting that HHV6 had transactivated B19V.In vitro experiments confirmed a 2.4-fold increased B19V P6-promoter activity by the HHV6 U94-transactivator.CONCLUSION:The finding of significantly increased B19V loads in patients with histologically proven cardiac inflammation suggests a crucial role of B19V-genotypes and reactivation of B19V-infection by HHV6-coinfection in B19V-associated iCMP.Our findings suggest that B19V-infection of the human heart can be a causative event for the development of an endothelial cell-mediated inflammatory disease and that this is related to both viral load and genotype.C-Thomas Bock Anja Düchting Friederike Utta Eva Brunner Bui Tien Sy Karin Klingel Florian Lang Meinrad Gawaz Stephan B Felix Reinhard Kandolf 2014World Journal of Cardiology2014,6,4:3
10Single port laparoscopy in gastroenterology and hepatology: A fine step forward显示文摘Single incision laparoscopy(SIL) has become an emerging technology aiming at a further reduction of abdominal wall trauma in minimally invasive surgery. Available data is encouraging for the safe application of standardized SIL in a wide range of procedures in gastroenterology and hepatology. Compared to technically simple SIL procedures, the merit of SIL in advanced surgeries, such as liver or colorectal interventions, compared to conventional laparsocopy is self-evident without any doubt. SIL has already passed the learning curve and is routinely utilized in expert centers. This minimized approach has allowed to enter a new era of surgical management that can not be acceded without a fruitful combination of prudent training, consistent day-to-day work and enthusiastic motivation for technical innovations. Both, basic and novel technical specifics as well as particular procedures are described herein. The focus is on the most important surgical interventions in gastroenterology and aims at reviewingthe current literature and shares our experience in a high volume center.Christof Mittermair Jan Schirnhofer Eberhard Brunner Katharina Pimpl Christian Obrist Michael Weiss Helmut G Weiss 2014World Journal of Gastroenterology2014,20,42:3
