2高首鲟背听侧核电感受神经元在电场刺激下的反应特性(英文)显示文摘目的软骨硬鳞鱼类的电感受是一种古老的感觉系统,它们通过电感受器官感受生物电场或非生物电场进行摄食等活动。支配电感受器的初级传入神经首先将电感受信息传递至后脑的背听侧核进行处理。本文探讨了鲟鱼背听侧核的电生理特性。方法采用胞外记录方法记录了高首鲟背听侧核在偶极子电场刺激下的神经元反应。结果背听侧核神经元有低频(<10Hz)自发放电和高频(>10Hz)自发放电两种,在电场刺激下均产生明显的自发放电的调制和相位耦合反应,同时部分神经元对偶极子电场的方向有选择性。结论鲟鱼的电感受神经元反应特征与其电感受的生物功能相适应。张旭光 Hendrik Herzog 宋佳坤 王晓杰 范纯新 郭弘艺 2011Neuroscience Bulletin2011,27,6:3
3采用意大利多中心前瞻性研究以评估16层及64层MDCT对计划行冠状动脉造影病人的阴性预测值(NIMISCAD-意大利冠心病无创性多中心性研究)显示文摘这是一项多中心的前瞻性研究.通过应用不同制造商生产的MDCT设备,对计划行选择性冠状动脉造影(CA)的病人行MDCT检查以对其诊断冠心病(CAD)的价值进行评估。2004年7月-2006年6月间.在20所国家医院前瞻性地征集了367例病人。对于每种类型的MDCT(≥16层),CT检查均采用标准化/优化的扫描方案,并且与2周内进行的定量冠状动脉造影比较。共有284例病人(81%)应用16层MDCT进行检查,66例病人(19%)应用64层MDCT进行检查。初步分析采用院内/院外的方法,评估对1例病人的阴性预测值(NPV)。R.

5Why are muscles strong, and why do they require little energy in eccentric action?显示文摘It is well acknowledged that muscles that are elongated while activated(i.e.,eccentric muscle action)are stronger and require less energy(per unit of force)than muscles that are shortening(i.e.,concentric contraction)or that remain at a constant length(i.e.,isometric contraction).Although the cross-bridge theory of muscle contraction provides a good explanation for the increase in force in active muscle lengthening,it does not explain the residual increase in force following active lengthening(residual force enhancement),or except with additional assumptions,the reduced metabolic requirement of muscle during and following active stretch.Aside from the cross-bridge theory,2 other primary explanations for the mechanical properties of actively stretched muscles have emerged:(1)the so-called sarcomere length nonuniformity theory and(2)the engagement of a passive structural element theory.In this article,these theories are discussed,and it is shown that the last of these—the engagement of a passive structural element in eccentric muscle action—offers a simple and complete explanation for many hitherto unexplained observations in actively lengthening muscle.Although by no means fully proven,the theory has great appeal for its simplicity and beauty,and even if over time it is shown to be wrong,it nevertheless forms a useful framework for direct hypothesis testing.Walter Herzog 2018Journal of Sport and Health Science2018,7,3:2
6Serotonin type 3 receptor subunit gene polymorphisms associated with psychosomatic symptoms in irritable bowel syndrome:A multicenter retrospective study显示文摘BACKGROUND Single-nucleotide polymorphisms(SNPs)of the serotonin type 3 receptor subunit(HTR3)genes have been associated with psychosomatic symptoms,but it is not clear whether these associations exist in irritable bowel syndrome(IBS).AIM To assess the association of HTR3 polymorphisms with depressive,anxiety,and somatization symptoms in individuals with IBS.METHODS In this retrospective study,623 participants with IBS were recruited from five specialty centers in Germany,Sweden,the United States,the United Kingdom,and Ireland.Depressive,anxiety,and somatization symptoms and sociodemographic characteristics were collected.Four functional SNPs—HTR3A c.-42C>T,HTR3B c.386A>C,HTR3C c.489C>A,and HTR3E c.*76G>A—were genotyped and analyzed using the dominant and recessive models.We also performed separate analyses for sex and IBS subtypes.SNP scores were calculated as the number of minor alleles of the SNPs above.The impact of HTR3C c.489C>A was tested by radioligand-binding and calcium influx assays.RESULTS Depressive and anxiety symptoms significantly worsened with increasing numbers of minor HTR3C c.489C>A alleles in the dominant model(F_(depressive)=7.475,P_(depressive)=0.006;F_(anxiety)=6.535,P_(anxiety)=0.011).A higher SNP score(range 0-6)was linked to a worsened depressive symptoms score(F=7.710,P-linear trend=0.006)in IBS.The potential relevance of the HTR3C SNP was corroborated,showing changes in the expression level of 5-HT3AC variant receptors.CONCLUSION We have provided the first evidence that HTR3C c.489C>A is involved in depressive and anxiety symptoms in individuals with IBS.The SNP score indicated that an increasing number of minor alleles is linked to the worsening of depressive symptoms in IBS.Sabrina Berens Yuanjun Dong Nikola Fritz Jutta Walstab Mauro D'Amato Tenghao Zheng Verena Wahl Felix Boekstegers Justo Lorenzo Bermejo Cristina Martinez Stefanie Schmitteckert Egbert Clevers Felicitas Engel Annika Gauss Wolfgang Herzog Robin Spiller Miriam Goebel-Stengel Hubert Mönnikes Viola Andresen Frieling Thomas Jutta Keller Christian Pehl Christoph Stein-Thöringer Gerard Clarke Timothy G Dinan Eamonn M Quigley Gregory Sayuk Magnus Simrén Jonas Tesarz Gudrun Rappold Lukas van Oudenhove Rainer Schaefert Beate Niesler 2022World Journal of Gastroenterology2022,28,21:2

8A comparison of lower limb stiffness and mechanical muscle function in ACL-reconstructed,elite,and adolescent alpine ski racers/ski cross athletes显示文摘Purpose: The aim of this study was to compare mechanical muscle function in the eccentric/concentric phases of vertical bilateral jumping in anterior cruciate ligament-reconstructed(ACLR), elite(ELITE), and adolescent(ADOL) alpine ski racers and ski cross athletes.Methods: Alpine ski racers/ski crossers(ACLR: n = 12, age = 26.7 § 3.8 years; ELITE: n = 12, age = 23.9 § 3.0 years; ADOL: n = 12, age = 17.8§ 0.7 years; females: n = 6 per group, males: n = 6 per group) performed 5 maximal countermovement jumps(CMJs) and 5 squat jumps. The ground reaction forces for each limb were analyzed using dual force plate recording to obtain body center of mass(BCM) velocity, displacement,and power. The eccentric deceleration(ECC) and concentric phases were determined from BCM velocity. CMJ net concentric and ECC impulses were calculated(body mass normalized) along with the peak and mean BCM power and maximal vertical jump height. CMJ lower limb stiffness(LLS) was determined by the slope of the ground reaction forces vs. the BCM displacement curve over the ECC phase. Concentric and ECC asymmetry indices were calculated for each leg, and the left vs. right LLS was compared. Outcome measures(reported as mean § SD) calculated as a 5-jump mean were normalized to body mass and compared using an analysis of variance.Results: No between-group differences were found for peak and mean power or jump heights. There were no group differences for LLS or net concentric phase impulse, but the net ECC impulse was lower in the ADOL group compared with ELITE skiers(ADOL: 1.33 § 0.32 Ns/kg;ELITE: 1.59 § 0.16 Ns/kg; p < 0.05). Although no group differences were found for ECC asymmetry indices, a group £ limb interaction was found for LLS(p < 0.01), which was systematically higher in the right vs. the left limb of ADOL skiers(right: 54.1 § 17.9 N/m/kg; left: 48.7 §15.7 N/m/kg; p < 0.01).Conclusion: ADOL skiers demonstrated decreased ECC impulse and systematic right limb dominance in LLS compared with ACLR and ELITE skiers. The implication of these findings for injury and performance are unknown, but further investigation into these potential relationships is warranted.matthew j.jordan per aagaard walter herzog 2018Journal of Sport and Health Science2018,7,4:2
