破骨细胞分化因子及其信号转导通路

破骨细胞分化因子及其信号转导通路破骨细胞负责骨吸收,来源于骨髓单核-巨噬细胞系,其分化需巨噬细胞发育必需集落刺激因子的参与。

破骨细胞形成和分化过程中所必须的细胞间信号转导则由骨保护蛋189白(OPG)以及核因子-κB(NF-κB)受体活化因子(RANK)及其配体(RANKL)系统介导。

RANKL-RANK-OPG信号转导通路在多种因子共同参与下,通过NF-κB、促丝裂原激活蛋白激酶和磷脂酰肌醇-3-激酶-蛋白激酶B等信号转导通路实现信号转导。

肿瘤坏死因子-α可刺激成骨细胞产生粒细胞-巨噬细胞集落刺激因子和白细胞介素(IL)-6等因子,诱使破骨细胞前体分化为破骨细胞。

一氧化氮和雌激素影响破骨细胞前体的分化。

整联蛋白-αβ3在破骨细胞诱导酪氨酸磷酸化与富含脯氨酸的酪氨酸激酶2及非受体依赖型蛋白酪氨酸激酶Src家族中的衔接蛋白P130 Crk相关的底物蛋白激活中至关重要,使骨产生吸收作用。

在破骨细胞及其前体中,转化生长因子-β受体、类固醇家庭受体、G-蛋白偶联受体、IL-1和非酪氨酸激酶细胞因子等对于破骨细胞功能的影响十分重要。

标签:破骨细胞;细胞因子;信号转导骨吸收和骨生成的动态平衡维持着骨组织的不断更新,而破骨细胞则负责骨的吸收。

Non-InvasiveandInvasiveCardiacImagingIntroduction

Non-InvasiveandInvasiveCardiacImagingIntroduction

Non-Invasive and Invasive Cardiac ImagingIntroduction:Coronary artery disease is the most common cause of patient hospitalization and mortality in many industrialized countries. The current standard of assessment is coronary angiography (CA) in conjunction with interventional therapeutic procedures. While CA and other invasive cardiac imaging procedures have become relatively safe, the inconvenience to the patient is extensive. This has caused a popularization throughout the past decades of potential, non-invasive cardiac imaging devices. Different devices such as magnetic resonance and electron beam computed tomography have been explored. In this monograph various imaging technologies are discussed.The Problem:The current cardiac imaging devices provide an inconvenience to the patient in many forms including hospitalization and higher economic burden. Various technologies have been developed to ease patient burden in the form of non-invasive cardiac imaging devices. However, these new technologies are not without their unique challenges. Such challenges as cardiac motion and calcium deposits often render scans inadequate. The characterization of atherosclerotic plaque is another major challenge for non-invasive imaging as the rupture of such plaques can cause acute vessel occlusion. There is a need to find a suitable procedure that minimizes or eliminates rupturing the plaque. In addition, conventional imaging techniques expose the patient to ionizing radiation. These are some of the various challenges surrounding the design of a non-invasive device.Invasive ImagingModern IVUS systems have presented some difficulties that necessitate further exploration. One such difficulty with IVUS is total obstruction when a transducer is brought in close proximity to a severely stenosed vessel. Volcano Corporation recently launched the VH ™ IVUS system. This is the first technology to enable real-time compositional assessment of atherosclerotic plaque in coronary arteries. It provides automated measurement tools to simplify image interpretation. It also uses a color key to better display plaque composition. This technology allows for colorized VH images of four plaque component types. This is the first IVUS system capable of providing information about plaque composition.Optical Coherence Tomography (OCT) is another popular technology used for cardiac imaging. This non-contact, light-based imaging modality providesin situ tissue images at near histological resolution. This technique allows for the identification of mural as well as luminal morphologies. When comparedto IVUS, studies showed that OCT provides additional morphologic information which is helpful in the characterization of plaque. Optical frequencydomain imaging (OFDI) is a new technology in this area of imaging. OFDI is used in the diagnosis and management of coronary artery disease. It uses infrared light delivered to the imaging site through a single optical fiber incorporated within a catheter. Advanced algorithms are used to remove thereflected signals from the infrared light. This provides the clinician with real-time cross sectional and 3-dimensional images.Non-invasive Imaging:Nuclear cardiac imaging is a popular non-invasive imaging method which uses technetium Tc 99m sestamibi (MIBI), a radionuclide, in its process. MIBI is a technetium imaging agent that is used to reveal blood-starved tissue, usually during a heart attack. It has been used for more than a decade as an imaging agent. MIBI concentrates in tissues in proportion to desmoplastic and metabolic activity and blood flow. This technique has been considered a reliable method of assessing myocardial salvage in patients with acute myocardial infarction in addition to evaluating and diagnosing a heart attack.(Nuclear cardiac illustration from Google Images)Cardiovascular Magnetic Resonance (CMR) is another technique used for non-invasive imaging. This device was developed to quantify calcium deposits and coronary morphology and flow. It is based upon the magnetic characteristics of tissues and molecules within a magnetic field. CMR is superior to other methods for use on those patients with complex congenital heart disease. CMR provides excellent visualization of extracardiac venous structures and intracardiac baffles as well. However, it is not feasible for use on patients with pacemakers or other metallic implants or on those who suffer from claustrophobia.Most recently, the technique of spiral balanced steady-state free precession cardiac imaging (SSFP) has been brought to the forefront of CMR. These sequences are useful in cardiac imaging because they have the ability to achieve high signal efficiency and blood-myocardium contrast. This procedure enables efficient acquisition with reduced blood flow and motion artifacts. SSPF has been combined with spiral imaging allowing for real-time interactive cardiac CMR. In contrast to conventional echo imaging, this method yields an intrinsic blood-myocardium contrast independent of inflow and has become extremely useful in cardiac imaging.Computed Tomography (CT) is another well-known device that is being used for non-invasive cardiac imaging. Like CMR, electron beam computed tomography (EBCT) was designed with the goal of measuring calcium deposits and coronary artery morphology and flow. CT of the heart throughout the last decade has been the exclusive realm of EBCT. The most popular use for this technology has been assessment of myocardial perfusion and function as well visualization of the coronary arteries.In recent years, multidetector-row computed tomography (MDCT) has become available. This technology has become the preferred method because it rectifies some of the limitations of the EBCT such as low special resolution and pronounced noise. The ability of the MDCT scanners to acquisition multiple slices has considerably improved cardiac imaging. The image quality produced by MDCT favorably compares to that of coronary angiography. In addition, it provides assessment of coronary calcium and plaque characterization while also producing a high image quality.Non-invasive echocardiography is an optional ultrasonic method of cardiac imaging. Recently, live three dimensional echocardiography (L3DE) has broken though into the field of medical ultrasound. This non-invasive system is easy to operate and images rapidly and clearly. In L3DE ultrasonic beams are generated in a phased array manner which gives the clinician the ability to evaluate the cardiac structures from every direction. The ability of the operator to improve temporal and special resolution of the image during acquisition is one benefit of this procedure.References and Bibliography:World Wide Web•http://www.mediguide.co.il/MediGuide-Medical Positioning System•Health Center Laboratories•Echocardiography (Ultrasound of the Heart)•Cardiac Perfusion Scan•Technetium tc 99m sestamibi-definition from •Google Images•/cgi/news/release?id=146453Press Release: Volcano Corp.

Peters (2010) Episodic Future Thinking Reduces Reward Delay Discounting

Peters (2010) Episodic Future Thinking Reduces Reward Delay Discounting

NeuronArticleEpisodic Future Thinking ReducesReward Delay Discounting through an Enhancement of Prefrontal-Mediotemporal InteractionsJan Peters1,*and Christian Bu¨chel11NeuroimageNord,Department of Systems Neuroscience,University Medical Center Hamburg-Eppendorf,Hamburg20246,Germany*Correspondence:j.peters@uke.uni-hamburg.deDOI10.1016/j.neuron.2010.03.026SUMMARYHumans discount the value of future rewards over time.Here we show using functional magnetic reso-nance imaging(fMRI)and neural coupling analyses that episodic future thinking reduces the rate of delay discounting through a modulation of neural decision-making and episodic future thinking networks.In addition to a standard control condition,real subject-specific episodic event cues were presented during a delay discounting task.Spontaneous episodic imagery during cue processing predicted how much subjects changed their preferences toward more future-minded choice behavior.Neural valuation signals in the anterior cingulate cortex and functional coupling of this region with hippo-campus and amygdala predicted the degree to which future thinking modulated individual preference functions.A second experiment replicated the behavioral effects and ruled out alternative explana-tions such as date-based processing and temporal focus.The present data reveal a mechanism through which neural decision-making and prospection networks can interact to generate future-minded choice behavior.INTRODUCTIONThe consequences of choices are often delayed in time,and in many cases it pays off to wait.While agents normally prefer larger over smaller rewards,this situation changes when rewards are associated with costs,such as delays,uncertainties,or effort requirements.Agents integrate such costs into a value function in an individual manner.In the hyperbolic model of delay dis-counting(also referred to as intertemporal choice),for example, a subject-specific discount parameter accurately describes how individuals discount delayed rewards in value(Green and Myer-son,2004;Mazur,1987).Although the degree of delay discount-ing varies considerably between individuals,humans in general have a particularly pronounced ability to delay gratification, and many of our choices only pay off after months or even years. It has been speculated that the capacity for episodic future thought(also referred to as mental time travel or prospective thinking)(Bar,2009;Schacter et al.,2007;Szpunar et al.,2007) may underlie the human ability to make choices with high long-term benefits(Boyer,2008),yielding higher evolutionaryfitness of our species.At the neural level,a number of models have been proposed for intertemporal decision-making in humans.In the so-called b-d model(McClure et al.,2004,2007),a limbic system(b)is thought to place special weight on immediate rewards,whereas a more cognitive,prefrontal-cortex-based system(d)is more involved in patient choices.In an alternative model,the values of both immediate and delayed rewards are thought to be repre-sented in a unitary system encompassing medial prefrontal cortex(mPFC),posterior cingulate cortex(PCC),and ventral striatum(VS)(Kable and Glimcher,2007;Kable and Glimcher, 2010;Peters and Bu¨chel,2009).Finally,in the self-control model, values are assumed to be represented in structures such as the ventromedial prefrontal cortex(vmPFC)but are subject to top-down modulation by prefrontal control regions such as the lateral PFC(Figner et al.,2010;Hare et al.,2009).Both the b-d model and the self-control model predict that reduced impulsivity in in-tertemporal choice,induced for example by episodic future thought,would involve prefrontal cortex regions implicated in cognitive control,such as the lateral PFC or the anterior cingulate cortex(ACC).Lesion studies,on the other hand,also implicated medial temporal lobe regions in decision-making and delay discounting. In rodents,damage to the basolateral amygdala(BLA)increases delay discounting(Winstanley et al.,2004),effort discounting (Floresco and Ghods-Sharifi,2007;Ghods-Sharifiet al.,2009), and probability discounting(Ghods-Sharifiet al.,2009).Interac-tions between the ACC and the BLA in particular have been proposed to regulate behavior in order to allow organisms to overcome a variety of different decision costs,including delays (Floresco and Ghods-Sharifi,2007).In line with thesefindings, impairments in decision-making are also observed in humans with damage to the ACC or amygdala(Bechara et al.,1994, 1999;Manes et al.,2002;Naccache et al.,2005).Along similar lines,hippocampal damage affects decision-making.Disadvantageous choice behavior has recently been documented in patients suffering from amnesia due to hippo-campal lesions(Gupta et al.,2009),and rats with hippocampal damage show increased delay discounting(Cheung and Cardinal,2005;Mariano et al.,2009;Rawlins et al.,1985).These observations are of particular interest given that hippocampal138Neuron66,138–148,April15,2010ª2010Elsevier Inc.damage impairs the ability to imagine novel experiences (Hassa-bis et al.,2007).Based on this and a range of other studies,it has recently been proposed that hippocampus and parahippocam-pal cortex play a crucial role in the formation of vivid event repre-sentations,regardless of whether they lie in the past,present,or future (Schacter and Addis,2009).The hippocampus may thus contribute to decision-making through its role in self-projection into the future (Bar,2009;Schacter et al.,2007),allowing an organism to evaluate future payoffs through mental simulation (Johnson and Redish,2007;Johnson et al.,2007).Future thinking may thus affect intertemporal choice through hippo-campal involvement.Here we used model-based fMRI,analyses of functional coupling,and extensive behavioral procedures to investigate how episodic future thinking affects delay discounting.In Exper-iment 1,subjects performed a classical delay discounting task(Kable and Glimcher,2007;Peters and Bu¨chel,2009)that involved a series of choices between smaller immediate and larger delayed rewards,while brain activity was measured using fMRI.Critically,we introduced a novel episodic condition that involved the presentation of episodic cue words (tags )obtained during an extensive prescan interview,referring to real,subject-specific future events planned for the respective day of reward delivery.This design allowed us to assess individual discount rates separately for the two experimental conditions,allowing us to investigate neural mechanisms mediating changes in delay discounting associated with episodic thinking.In a second behavioral study,we replicated the behavioral effects of Exper-iment 1and addressed a number of alternative explanations for the observed effects of episodic tags on discount rates.RESULTSExperiment 1:Prescan InterviewOn day 1,healthy young volunteers (n =30,mean age =25,15male)completed a computer-based delay discounting proce-dure to estimate their individual discount rate (Peters and Bu ¨-chel,2009).This discount rate was used solely for the purpose of constructing subject-specific trials for the fMRI session (see Experimental Procedures ).Furthermore,participants compiled a list of events that they had planned in the next 7months (e.g.,vacations,weddings,parties,courses,and so forth)andrated them on scales from 1to 6with respect to personal rele-vance,arousal,and valence.For each participant,seven subject-specific events were selected such that the spacing between events increased with increasing delay to the episode,and that events were roughly matched based on personal rele-vance,arousal,and valence.Multiple regression analysis of these ratings across the different delays showed no linear effects (relevance:p =0.867,arousal:p =0.120,valence:p =0.977,see Figure S1available online).For each subject,a separate set of seven delays was computed that was later used as delays in the control condition.Median and range for the delays used in each condition are listed in Table S1(available online).For each event,a label was selected that would serve as a verbal tag for the fMRI session.Experiment 1:fMRI Behavioral ResultsOn day 2,volunteers performed two sessions of a delay dis-counting procedure while fMRI was measured using a 3T Siemens Scanner with a 32-channel head-coil.In each session,subjects made a total of 118choices between 20V available immediately and larger but delayed amounts.Subjects were told that one of their choices would be randomly selected and paid out following scanning,with the respective delay.Critically,in half the trials,an additional subject-specific episodic tag (see above,e.g.,‘‘vacation paris’’or ‘‘birthday john’’)was displayed based on the prescan interview (see Figure 1)indicating which event they had planned on the particular day (episodic condi-tion),whereas in the remaining trials,no episodic tag was pre-sented (control condition).Amount and waiting time were thus displayed in both conditions,but only the episodic condition involved the presentation of an additional subject-specific event tag.Importantly,nonoverlapping sets of delays were used in the two conditions.Following scanning,subjects rated for each episodic tag how often it evoked episodic associations during scanning (frequency of associations:1,never;to 6,always)and how vivid these associations were (vividness of associa-tions:1,not vivid at all;to 6,highly vivid;see Figure S1).Addition-ally,written reports were obtained (see Supplemental Informa-tion ).Multiple regression revealed no significant linear effects of delay on postscan ratings (frequency:p =0.224,vividness:p =0.770).We averaged the postscan ratings acrosseventsFigure 1.Behavioral TaskDuring fMRI,subjects made repeated choices between a fixed immediate reward of 20V and larger but delayed amounts.In the control condi-tion,amounts were paired with a waiting time only,whereas in the episodic condition,amounts were paired with a waiting time and a subject-specific verbal episodic tag indicating to the subjects which event they had planned at the respective day of reward delivery.Events were real and collected in a separate testing session prior to the day of scanning.NeuronEpisodic Modulation of Delay DiscountingNeuron 66,138–148,April 15,2010ª2010Elsevier Inc.139and the frequency/vividness dimensions,yielding an‘‘imagery score’’for each subject.Individual participants’choice data from the fMRI session were then analyzed byfitting hyperbolic discount functions to subject-specific indifference points to obtain discount rates (k-parameters),separately for the episodic and control condi-tions(see Experimental Procedures).Subjective preferences were well-characterized by hyperbolic functions(median R2 episodic condition=0.81,control condition=0.85).Discount functions of four exemplary subjects are shown in Figure2A. For both conditions,considerable variability in the discount rate was observed(median[range]of discount rates:control condition=0.014[0.003–0.19],episodic condition=0.013 [0.002–0.18]).To account for the skewed distribution of discount rates,all further analyses were conducted on the log-trans-formed k-parameters.Across subjects,log-transformed discount rates were significantly lower in the episodic condition compared with the control condition(t(29)=2.27,p=0.016),indi-cating that participants’choice behavior was less impulsive in the episodic condition.The difference in log-discount rates between conditions is henceforth referred to as the episodic tag effect.Fitting hyperbolic functions to the median indifference points across subjects also showed reduced discounting in the episodic condition(discount rate control condition=0.0099, episodic condition=0.0077).The size of the tag effect was not related to the discount rate in the control condition(p=0.56). We next hypothesized that the tag effect would be positively correlated with postscan ratings of episodic thought(imagery scores,see above).Robust regression revealed an increase in the size of the tag effect with increasing imagery scores (t=2.08,p=0.023,see Figure2B),suggesting that the effect of the tags on preferences was stronger the more vividly subjects imagined the episodes.Examples of written postscan reports are provided in the Supplemental Results for participants from the entire range of imagination ratings.We also correlated the tag effect with standard neuropsychological measures,the Sensation Seeking Scale(SSS)V(Beauducel et al.,2003;Zuck-erman,1996)and the Behavioral Inhibition Scale/Behavioral Approach Scale(BIS/BAS)(Carver and White,1994).The tag effect was positively correlated with the experience-seeking subscale of the SSS(p=0.026)and inversely correlated with the reward-responsiveness subscale of the BIS/BAS scales (p<0.005).Repeated-measures ANOVA of reaction times(RTs)as a func-tion of option value(lower,similar,or higher relative to the refer-ence option;see Experimental Procedures and Figure2C)did not show a main effect of condition(p=0.712)or a condition 3value interaction(p=0.220),but revealed a main effect of value(F(1.8,53.9)=16.740,p<0.001).Post hoc comparisons revealed faster RTs for higher-valued options relative to similarly (p=0.002)or lower valued options(p<0.001)but no difference between lower and similarly valued options(p=0.081).FMRI DataFMRI data were modeled using the general linear model(GLM) as implemented in SPM5.Subjective value of each decision option was calculated by multiplying the objective amount of each delayed reward with the discount fraction estimated behaviorally based on the choices during scanning,and included as a parametric regressor in the GLM.Note that discount rates were estimated separately for the control and episodic conditions(see above and Figure2),and we thus used condition-specific k-parameters for calculation of the subjective value regressor.Additional parametric regressors for inverse delay-to-reward and absolute reward magnitude, orthogonalized with respect to subjective value,were included in theGLM.Figure2.Behavioral Data from Experiment1Shown are experimentally derived discount func-tions from the fMRI session for four

as a measure of the effect of the episodictags on choice preferences.(B)Robust regressionrevealed an association between log-differences indiscount rates and imagery scores obtained frompostscan ratings(see text).(C)RTs were signifi-cantly modulated by option value(main effectvalue p<0.001)with faster responses in trialswith a value of the delayed reward higher thanthe20V reference amount.Note that althoughseven delays were used for each condition,somedata points are missing,e.g.,onlyfive delay indif-ference points for the episodic condition areplotted for sub20.This indicates that,for the twolongest delays,this subject never chose the de-layed reward.***p<0.005.Error bars=SEM.Neuron Episodic Modulation of Delay Discounting140Neuron66,138–148,April15,2010ª2010Elsevier Inc.Episodic Tags Activate the Future Thinking NetworkWe first analyzed differences in the condition regressors without parametric pared to those of the control condi-tion,BOLD responses to the presentation of the delayed reward in the episodic condition yielded highly significant activations (corrected for whole-brain volume)in an extensive network of brain regions previously implicated in episodic future thinking (Addis et al.,2007;Schacter et al.,2007;Szpunar et al.,2007)(see Figure 3and Table S2),including retrosplenial cortex (RSC)/PCC (peak MNI coordinates:À6,À54,14,peak z value =6.26),left lateral parietal cortex (LPC,À44,À66,32,z value =5.35),and vmPFC (À8,34,À12,z value =5.50).Distributed Neural Coding of Subjective ValueWe then replicated previous findings (Kable and Glimcher,2007;Kable and Glimcher,2010;Peters and Bu¨chel,2009)using a conjunction analysis (Nichols et al.,2005)searching for regions showing a positive correlation between the height of the BOLD response and subjective value in the control and episodic condi-tions in a parametric analysis (Figure 4A and Table S3).Note that this is a conservative analysis that requires that a given voxel exceed the statistical threshold in both contrasts separately.This analysis revealed clusters in the lateral orbitofrontal cortex (OFC,À36,50,À10,z value =4.50)and central OFC (À18,12,À14,z value =4.05),bilateral VS (right:10,8,0,z value =4.22;left:À10,8,À6,z value =3.51),mPFC (6,26,16,z value =3.72),and PCC (À2,À28,24,z value =4.09),representing subjective (discounted)value in both conditions.We next analyzed the neural tag effect,i.e.,regions in which the subjective value correlation was greater for the episodic condi-tion as compared with the control condition (Figure 4B and Table S4).This analysis revealed clusters in the left LPC (À66,À42,32,z value =4.96,),ACC (À2,16,36,z value =4.76),left dorsolateral prefrontal cortex (DLPFC,À38,36,36,z value =4.81),and right amygdala (24,2,À24,z value =3.75).Finally,we performed a triple-conjunction analysis,testing for regions that were correlated with subjective value in both conditions,but in which the value correlation increased in the episodic condition.Only left LPC showed this pattern (À66,À42,30,z value =3.55,see Figure 4C and Table S5),the same region that we previously identified as delay-specific in valuation (Petersand Bu¨chel,2009).There were no regions in which the subjective value correlation was greater in the control condition when compared with the episodic condition at p <0.001uncorrected.ACC Valuation Signals and Functional Connectivity Predict Interindividual Differences in Discount Function ShiftsWe next correlated differences in the neural tag effect with inter-individual differences in the size of the behavioral tag effect.To this end,we performed a simple regression analysis in SPM5on the single-subject contrast images of the neural tag effect (i.e.,subjective value correlation episodic >control)using the behavioral tag effect [log(k control )–log(k episodic )]as an explana-tory variable.This analysis revealed clusters in the bilateral ACC (right:18,34,18,z value =3.95,p =0.021corrected,left:À20,34,20,z value =3.52,Figure 5,see Table S6for a complete list).Coronal sections (Figure 5C)clearly show that both ACC clusters are located in gray matter of the cingulate sulcus.Because ACC-limbic interactions have previously been impli-cated in the control of choice behavior (Floresco and Ghods-Sharifi,2007;Roiser et al.,2009),we next analyzed functional coupling with the right ACC from the above regression contrast (coordinates 18,34,18,see Figure 6A)using a psychophysiolog-ical interaction analysis (PPI)(Friston et al.,1997).Note that this analysis was conducted on a separate first-level GLM in which control and episodic trials were modeled as 10s miniblocks (see Experimental Procedures for details).We first identified regions in which coupling with the ACC changed in the episodic condition compared with the control condition (see Table S7)and then performed a simple regression analysis on these coupling parameters using the behavioral tag effect as an explanatory variable.The tag effect was associated with increased coupling between ACC and hippocampus (À32,À18,À16,z value =3.18,p =0.031corrected,Figure 6B)and ACC and left amygdala (À26,À4,À26,z value =2.95,p =0.051corrected,Figure 6B,see Table S8for a complete list of activa-tions).The same regression analysis in a second PPI with the seed voxel placed in the contralateral ACC region from the same regression contrast (À20,34,22,see above)yielded qual-itatively similar,though subthreshold,results in these same structures (hippocampus:À28,À32,À6,z value =1.96,amyg-dala:À28,À6,À16,z value =1.97).Experiment 2We conducted an additional behavioral experiment to address a number of alternative explanations for the observed effects of tags on choice behavior.First,it could be argued thatepisodicFigure 3.Categorical Effect of Episodic Tags on Brain ActivityGreater activity in lateral parietal cortex (left)and posterior cingulate/retrosplenial and ventro-medial prefrontal cortex (right)was observed in the episodic condition compared with the control condition.p <0.05,FWE-corrected for whole-brain volume.NeuronEpisodic Modulation of Delay DiscountingNeuron 66,138–148,April 15,2010ª2010Elsevier Inc.141tags increase subjective certainty that a reward would be forth-coming.In Experiment 2,we therefore collected postscan ratings of reward confidence.Second,it could be argued that events,always being associated with a particular date,may have shifted temporal focus from delay-based to more date-based processing.This would represent a potential confound,because date-associated rewards are discounted less than delay-associated rewards (Read et al.,2005).We therefore now collected postscan ratings of temporal focus (date-based versus delay-based).Finally,Experiment 1left open the question of whether the tag effect depends on the temporal specificity of the episodic cues.We therefore introduced an additional exper-imental condition that involved the presentation of subject-specific temporally unspecific future event cues.These tags (henceforth referred to as unspecific tags)were obtained by asking subjects to imagine events that could realistically happen to them in the next couple of months,but that were not directly tied to a particular point in time (see Experimental Procedures ).Episodic Imagery,Not Temporal Specificity,Reward Confidence,or Temporal Focus,Predicts the Size of the Tag EffectIn total,data from 16participants (9female)are included.Anal-ysis of pretest ratings confirmed that temporally unspecific and specific tags were matched in terms of personal relevance,arousal,valence,and preexisting associations (all p >0.15).Choice preferences were again well described by hyperbolic functions (median R 2control =0.84,unspecific =0.81,specific =0.80).We replicated the parametric tag effect (i.e.,increasing effect of tags on discount rates with increasing posttest imagery scores)in this independent sample for both temporally specific (p =0.047,Figure 7A)and temporally unspecific (p =0.022,Figure 7A)tags,showing that the effect depends on future thinking,rather than being specifically tied to the temporal spec-ificity of the event cues.Following testing,subjects rated how certain they were that a particular reward would actually be forth-coming.Overall,confidence in the payment procedure washighFigure 4.Neural Representation of Subjective Value (Parametric Analysis)(A)Regions in which the correlation with subjective value (parametric analysis)was significant in both the control and the episodic conditions (conjunction analysis)included central and lateral orbitofrontal cortex (OFC),bilateral ventral striatum (VS),medial prefrontal cortex (mPFC),and posterior cingulate cortex(PCC),replicating previous studies (Kable and Glimcher,2007;Peters and Bu¨chel,2009).(B)Regions in which the subjective value correlation was greater for the episodic compared with the control condition included lateral parietal cortex (LPC),ante-rior cingulate cortex (ACC),dorsolateral prefrontal cortex (DLPFC),and the right amygdala (Amy).(C)A conjunction analysis revealed that only LPC activity was positively correlated with subjective value in both conditions,but showed a greater regression slope in the episodic condition.No regions showed a better correlation with subjective value in the control condition.Error bars =SEM.All peaks are significant at p <0.001,uncorrected;(A)and (B)are thresholded at p <0.001uncorrected and (C)is thresholded at p <0.005,uncorrected for display purposes.NeuronEpisodic Modulation of Delay Discounting142Neuron 66,138–148,April 15,2010ª2010Elsevier Inc.(Figure 7B),and neither unspecific nor specific tags altered these subjective certainty estimates (one-way ANOVA:F (2,45)=0.113,p =0.894).Subjects also rated their temporal focus as either delay-based or date-based (see Experimental Procedures ),i.e.,whether they based their decisions on the delay-to-reward that was actually displayed,or whether they attempted to convert delays into the corresponding dates and then made their choices based on these dates.There was no overall significant effect of condition on temporal focus (one-way ANOVA:F (2,45)=1.485,p =0.237,Figure 7C),but a direct comparison between the control and the temporally specific condition showed a significant difference (t (15)=3.18,p =0.006).We there-fore correlated the differences in temporal focus ratings between conditions (control:unspecific and control:specific)with the respective tag effects (Figure 7D).There were no correlations (unspecific:p =0.71,specific:p =0.94),suggesting that the observed differences in discounting cannot be attributed to differences in temporal focus.High-Imagery,but Not Low-Imagery,Subjects Adjust Their Discount Function in an Episodic ContextFor a final analysis,we pooled the samples of Experiments 1and 2(n =46subjects in total),using only the temporally specific tag data from Experiment 2.We performed a median split into low-and high-imagery participants according to posttest imagery scores (low-imagery subjects:n =23[15/8Exp1/Exp2],imagery range =1.5–3.4,high-imagery subjects:n =23[15/8Exp1/Exp2],imagery range =3.5–5).The tag effect was significantly greater than 0in the high-imagery group (t (22)=2.6,p =0.0085,see Figure 7D),where subjects reduced their discount rate by onaverage 16%in the presence of episodic tags.In the low-imagery group,on the other hand,the tag effect was not different from zero (t (22)=0.573,p =0.286),yielding a significant group difference (t (44)=2.40,p =0.011).DISCUSSIONWe investigated the interactions between episodic future thought and intertemporal decision-making using behavioral testing and fMRI.Experiment 1shows that reward delay dis-counting is modulated by episodic future event cues,and the extent of this modulation is predicted by the degree of sponta-neous episodic imagery during decision-making,an effect that we replicated in Experiment 2(episodic tag effect).The neuroi-maging data (Experiment 1)highlight two mechanisms that support this effect:(1)valuation signals in the lateral ACC and (2)neural coupling between ACC and hippocampus/amygdala,both predicting the size of the tag effect.The size of the tag effect was directly related to posttest imagery scores,strongly suggesting that future thinking signifi-cantly contributed to this effect.Pooling subjects across both experiments revealed that high-imagery subjects reduced their discount rate by on average 16%in the episodic condition,whereas low-imagery subjects did not.Experiment 2addressed a number of alternative accounts for this effect.First,reward confidence was comparable for all conditions,arguing against the possibility that the tags may have somehow altered subjec-tive certainty that a reward would be forthcoming.Second,differences in temporal focus between conditions(date-basedFigure 5.Correlation between the Neural and Behavioral Tag Effect(A)Glass brain and (B and C)anatomical projection of the correlation between the neural tag effect

Gill D 1, Intrator N 2, Gavriely N3 1 Department of Statistics, The Hebrew University of Jerusalem, Jerusalem 91905, Israel, 2 School of Computer Science, Tel Aviv University, Tel Aviv 69978, Israel, 3Rappaport Medicine Faculty, Technion IIT, Haifa 31096, Israel gill@mta.ac.il Abstract. This work presents a novel method for automatic detection and identification of heart sounds. Homomorphic filtering is used to obtain a smooth envelogram of the phonocardiogram, which enables a robust detection of events of interest in heart sound signal. Sequences of features extracted from the detected events are used as observations of a hidden Markov model. It is demonstrated that the task of detection and identification of the major heart sounds can be learned from unlabelled phonocardiograms by an unsupervised training process and without the assistance of any additional synchronizing channels.

由此形成了一门细胞学科-电生理学(electrophysiology ),即是用电生理的方法来记录和分析细胞产生电的大小和规律的科学。

早期的研究多使用双电极电压钳技术作细胞内电活动的记录。

现代膜片钳技术是在电压钳技术的基,上发展起来的1976年德国马普生物物理研究所Neher和Sakmann创建了膜片钳技术(patch clamp recording technique )。

这是一种以记录通过离子通道的离子电流来反映细胞膜单一的(或多个的离子通道分子活动的技术)。

以后由于吉欧姆阻抗封接(gigaohm seal, 109W)方法的确立和几种方法的创建。

这种技术点燃了细胞和分子水平的生理学研究的革命之火,它和基因克隆技术( gene cloning )并架齐驱,给生命科学研究带来了巨大的前进动力这一伟大的贡献,使Neher和Sakmann获得1991年度的诺贝尔生理学与医学奖、膜片钳技术发展历史1976年德国马普生物物理化学研究所Neher和Sakmann首次在青蛙肌细胞上用双电极钳制膜电位的同时,记录到ACh激活的单通道离子电流,从而产生了膜片钳技术。

1980年Sigworth等在记录电极内施加5-50 cmH20的负压吸引,得到10-100GW10-100G? 的高阻封接(Giga-seal ),大大降低了记录时的噪声实现了单根电极既钳制膜片电位又记录单通道电流的突破。

1981年Hamill和Neher等对该技术进行了改进,引进了膜片游离技术和全细胞记录技术,从而使该术更趋完善,具有1pA的电流灵敏度、1g m的空间分辨率和10g s的时间分辨率1983年10月,《Single-Channel Recording》一书问世,奠定了膜片钳技术的里程碑。

腺苷酸活化蛋白激酶病酷似肥厚性心肌病和预激综合征:自然病史

腺苷酸活化蛋白激酶病酷似肥厚性心肌病和预激综合征:自然病史Murphy R.T.;Mogensen J.;McGarry K.;W.J. McKenna;吴波【期刊名称】《世界核心医学期刊文摘:心脏病学分册》【年(卷),期】2005(000)009【摘要】OBJECTIVES: The aim of this study was to investigate the clinical expression of adenosine monophosphate-activated protein kinase(AMPK) gene mutations(PRKAG2) in adenosine monophosphate(AMP) kinase disease based on 12 years follow-up of known mutation carriers and to define the prevalence of PRKAG2 mutations in hypertrophic cardiomyopathy(HCM). BACKGROUND:Adenosine mono-phosphate-activated protein kinase genemutations cause HCM withWolff-Parkinson-White syndrome and conduction disease. METHODS: Clinical evaluation of 44 patients with known AMP kinase disease was analyzed. Mutation analysis of PRKAG2 was performed by fluorescent single-strand confirmation polymorphism analysis and direct sequencing of abnormal conformers in 200 patients with HCM. RESULTS: Only one additional mutation was identified. The mean age at clinical diagnosis in the 45 gene carriers was 24 years(median 20 years, range 9 to 55 years). Symptoms of palpitation, dypspnea, chest pain, or syncope were present in 31(69%) gene carriers; 7(15%) complained of myalgia and had clinical evidence of proximal myopathy. Skeletal muscle biopsy showed excess mitochondriaand ragged red fibers with minimal glycogen accumulation. Disease penetrance defined by typical electrocardiogram abnormalities was 100%by age 18 years. Thirty-two of 41 adults(78%) had left ventricular hypertrophy(LVH) on echocardiography, and progressive LVH was documented during follow-up. Survival was 91%at a mean follow-up of 12.2 years. Progressive conduction disease required pacemaker implantation in 17 of 45(38%) at a mean age of 38 years. CONCLUSIONS: The AMP kinase disease is uncommon in HCM and is characterized by progressive conduction disease and cardiac hypertrophy and includes extracardiac manifestations such as a skeletal myopathy, consistent with a systemic metabolic storage disease. Defects in adenosine triphosphate utilization or in specific cellular substrates, rather than mere passive deposition of amylopectin, may account for these clinical features.【总页数】2页(P60-61)【作者】Murphy R.T.;Mogensen J.;McGarry K.;W.J.

平滑肌肌球蛋白轻链激酶对肌球蛋白非Ca2+依赖性磷酸化(2)唐泽耀;陈华;杨静娴;王晓明;林原【期刊名称】《科学技术与工程》【年(卷),期】2005(005)006【摘要】为初步揭示肌球蛋白轻链激酶(MLCK)对肌球蛋白(myosin)非Ca2+依赖性磷酸化的特征.试验方法采用10%甘油聚丙烯酰胺凝胶电泳检测myosin的磷酸化,用孔雀绿法测定myosin Mg2+-ATP酶活性及选择Scoin Image扫描软件分析所获得的数据.提出在MLCK参与的myosin活性调节中,myosin以非磷酸化、非Ca2+依赖性(CIPM)及Ca2+依赖性磷酸化(CDPM)三种状态存在.研究发现非Ca2+依赖性磷酸化myosin有以下特征:(1)耗能(Mg2+-ATP酶活性)高于非磷酸化myosin但低于Ca2+依赖性磷酸化myosin;(2)花生四烯酸(AA)可选择性加强myosin非Ca2+依赖性磷酸化;(3)在本试验条件下,未观察到MLCK抑制剂ML-9对非Ca2+依赖性myosin磷酸化的抑制作用;(4)组胺(histamine)对非Ca2+依赖性的抑制小于对Ca2+依赖性磷酸化的抑制,且这些差异在统计学上有显著性.以上结果提示myosin非Ca2+依赖性磷酸化不仅在程度上,而且在机制上与Ca2+依赖性磷酸化可能存在重要区别.【总页数】5页(P332-336)【作者】唐泽耀;陈华;杨静娴;王晓明;林原【作者单位】大连医科大学药理教研室,大连,116027;大连医科大学药理教研室,大连,116027;大连医科大学药理教研室,大连,116027;大连医科大学药理教研室,大连,116027;大连医科大学药理教研室,大连,116027【正文语种】中文【中图分类】Q512.2【相关文献】1.miR-200b调控肌球蛋白轻链激酶/磷酸化肌球蛋白轻链信号通路对肠上皮紧密连接的影响 [J], 沈玉洁;张琮;陈颖伟2.平滑肌肌球蛋白轻链激酶对肌球蛋白的非钙依赖性磷酸化 [J], 林原;唐泽耀;陈华;戴淑芳;杨静娴;王晓明3.肌球蛋白轻链激酶介导的肌球蛋白调节轻链磷酸化研究 [J], 高文;李科;李雪萍;李亚;宋梅4.平滑肌肌球蛋白轻链激酶的非激酶作用及对ATP酶活性的调节 [J], 崔颖;李晓丽;梁明丽;陈海波;高颖5.平滑肌细胞迁移的肌球蛋白轻链非磷酸化途径 [J], 叶丽虹;郭威;赵铁军;张伟英;叶婷婷;吴晶辉;张晓东因版权原因,仅展示原文概要,查看原文内容请购买。

体外血管钙化与细胞增殖的关系及其氟伐他汀对钙化影响的实验研究

体外血管钙化与细胞增殖的关系及其氟伐他汀对钙化影响的实验研究

体外血管钙化与细胞增殖的关系及其氟伐他汀对钙化影响的实验研究目的:本研究通过β-甘油磷酸盐处理牛主动脉平滑肌细胞,建立细胞水平的体外血管钙化模型,借此观察多种非胶原类骨基质蛋白钙化期间的表达、分泌情况,以及细胞增殖、细胞凋亡/死亡情况,初步探讨其可能的机制。

此外,加用氟伐他汀进行干预,观察其对体外血管钙化的影响并探讨可能的作用机制。

方法:(1)第一部分:组织块法原代培养牛主动脉中膜平滑肌细胞。

选用8代以内的传代细胞,添加终浓度为10mmol/L β-甘油磷酸盐培养10天诱导钙化;利用Von Kossa染色、茜素红-S染色及检测细胞层钙沉积对钙化进行鉴定,同时观察细胞层碱性磷酸酶活性和培养上清骨钙素含量。

(2)第二部分:采用噻唑兰(MTT)比色试验、台盼兰排斥试验观察不同浓度β-甘油磷酸盐对牛主动脉平滑肌细胞增殖的影响,利用流式细胞分析术观察钙化期间细胞凋亡、细胞周期的情况。

(3)第三部分:体外血管钙化期间,添加终浓度为10<sup>-6</sup>、10<sup>-7</sup>、10<sup>-8</sup>mol/L氟伐他汀进行干预,检测细胞层钙沉积、碱性磷酸酶活性和培养上清骨钙素含量,观察氟伐他汀对钙化的影响;利用RT-PCR、Western blot方法检测正常培养细胞、钙化组及氟伐他汀治疗组的骨桥蛋白、骨连接素基因、蛋白水平的表达情况。

结果:(1)β-甘油磷酸盐处理10天后,光镜及电镜显示培养细胞出现广泛分布的钙盐沉积,Von Kossa、茜素红-S钙染色均呈阳性,细胞层钙沉积升至正常对照的28.44倍,较实验初增加了293倍(P<0.01),从而证实体外血管钙化模型建立成功。

(2)β-甘油磷酸盐能够时间依赖性增加细胞层钙沉积,细胞层碱性磷酸酶活性、培养上清骨钙素含量也随时间的延长而增高,各时间点均高于正常对照(P<0.01);此外,RT-PCR、Western blot证实钙化组的骨桥蛋白mRNA及蛋白表达明显增高,而骨连接素mRNA及蛋旱巨域修斗腕协士学位公义幻县白表达略有下降。

上皮型钙粘蛋白在小鼠胚胎干细胞体外分化中动态表达及与细胞黏附状态关系

上皮型钙粘蛋白在小鼠胚胎干细胞体外分化中动态表达及与细胞黏附状态关系胡安斌;何晓顺;黄冰;蔡继业【期刊名称】《中国组织工程研究》【年(卷),期】2009(013)045【摘要】背景:体内胚胎期,上皮型钙粘蛋白对肝脏组织的发育起到决定作用,探讨其在胚胎干细胞分化中的动态表达对于肝脏组织的体外发育可行性具有重要意义.目的:观察上皮型钙粘蛋白在小鼠胚胎干细胞体外分化过程中的动态表达,及其与细胞间黏附状态的关系.设计、时间及地点:细胞学体外观察,于2007-12/2098-12在中山大学附属第一医院外科实验室完成.材料:BALB/c系小鼠胚胎干细胞由中山大学眼科中心黄冰教授建系和保存.清洁级BALB/c系孕13 d小鼠20只,由中山大学实验动物中心提供.方法:BALB/c系小鼠胚胎干细胞克隆经胰酶消化后,利用含胎牛血清、2-巯基乙醇、HEPES、青霉素、链霉素的DMEM培养基悬浮培养,使其自然发育5 d形成拟胚体,第6天转至培养板使其贴壁生长.取BALB/c系孕13 d小鼠,取其胎鼠肝脏组织制备胎肝细胞及冰冻切片,作为对照组.主要观察指标:按胚胎干细胞初分化、拟胚体形成、细胞分化群落形成等阶段,于细胞分化第1,5,9,13,17天利用RT-PCR和免疫细胞化学法检测上皮型钙粘蛋白的表达,观察其表达水平与细胞黏附状态的关系.结果:RT-PCR检测结果显示,在胚胎干细胞自然分化系统中,上皮型钙粘蛋白mRNA于分化第1天未表达,在第5天拟胚体形成后表达最强,其后表达能力逐渐降低,至17 d时不再表达,作为对照的BALB/c系小鼠胎肝细胞表达较强的上皮型钙粘蛋白mRNA.免疫细胞化学检测结果亦体现相同规律.胚胎干细胞在形态学上由单细胞发育为致密的包含3胚层结构的拟胚体,再继续分化为松散的细胞群落.结论:上皮型钙粘蛋白在胚胎干细胞体外培养系统中的表达水平与分化细胞间黏附状态变化呈一定的相关性,其在体外环境中丧失表达可能是分化细胞不能组织化的一个重要原因.【总页数】5页(P8838-8842)【作者】胡安斌;何晓顺;黄冰;蔡继业【作者单位】中山大学附属第一医院器官移植中心,广东省,广州市,510080;中山大学附属第一医院器官移植中心,广东省,广州市,510080;中山大学眼科中心,广东省,广州市,510080;暨南大学生命科学院,广东省,广州市,510632【正文语种】中文【中图分类】R394.2【相关文献】1.在小鼠胚胎干细胞系嵌入碳酸盐碳灰石DNA载体的上皮细胞钙粘蛋白及纤维蛋白元细胞粘附蛋白对转基因的运输和表达的影响 [J], 徐李;曾忠良2.上皮型钙粘蛋白在肿瘤中的表达及与肝癌转移和预后关系研究进展 [J], 赵世元;王乃平3.胃癌上皮型钙粘蛋白表达及其与浸润转移的关系 [J], 樊克武;赵建华4.上皮型钙粘蛋白基因稳定转染小鼠胚胎干细胞及对分化细胞黏附能力的影响 [J], 胡安斌;何晓顺;黄冰;蔡继业5.大肠癌上皮型钙粘蛋白表达及其与浸润转移的关系 [J], 樊克武;赵建华;李俐因版权原因,仅展示原文概要,查看原文内容请购买。

THE END OF
CHAPTER 4
Tilkian, Ara MD Understanding Heart Sounds and Murmurs, Fourth Edition, W.B. Sunders Company. 2019, pp. 34-42.
• IC represents isovolumic contraction and coincides with the first vibrations of the first heart sound
• E peak reflects thblood from the ventricle into the aorta and coincides with 3rd heart sound
Apexcardiogram (ACG)
• Records low-frequency vibrations over the apical impulse
• Defections not delayed
• A wave reflects atrial contraction and is synchronous with the 4th heart sound
Phonocardiography, External Pulse Recordings,
and Echocardiography
Ara G. Tilkian, MD, FACC Instructor
Patricia L. Thomas, MBA, RCIS
Phonocardiography
• A graphic recording of cardiac sound • A specially designed microphone on the
• O point reflects the opening of the mitral valve • RFW (rapid filling wave) marks the 3rd heart sound and
early rapid phase of ventricular filling
Echocardiography
• T (tidal wave) is the second wave and occurs late in systole
• D (dicrotic notch) coincides with aortic closure (A2), plus the traveling time of the pulse to the neck (.01-.05 sec)
• Echocardiography uses echoes from pulsed highfrequency sound waves to locate and study the movements and dimensions of various cardiac structures
• M-Mode angle of ultrasound kept stationary
Electrocardiogram
• Does not correlate exactly with ventricular systole and diastole
• Electrical event of depolarization precedes the mechanical contraction by approximately .02 sec.
• Two-Dimensional the angle issues very high-frequency sound waves to produce visual images of the anatomical structures of the heart (sector scan)
• Doppler explores the blood flow patterns in the cardiac chambers. It determines the direction of blood flow and measures its velocity within the heart and great vessels. The information is used to estimate gradients across cardiac valves and detect regurgitations.
Causes of Abnormalities in the Carotid Pulse
Jugular Pulse Tracing (JPT)
• Reflects volume change in the internal jugular vein and closely resembles the pressure changes in the right atrium
• A wave atrial contraction • C wave onset of ventricular contraction • X descent atrial diastole • V wave atrial filling before AV valves open • Y descent AV valves open filling of the ventricles
Carotid Pulse Tracing (CPT)
• Reflects the pressure and possible small volume changes in a segment of the carotid artery with each cardiac cycle
• P (percussion wave) is the first peak and is related to aortic ejection. 80 msec after the first heart sound
chest wall • Sound waves amplified, filtered and
recorded • Doppler Echocardiography has replaced the
phonocardiography • Maybe coming back in the future
