Transient Biventricular Apical Ballooning: A Unique Presentation of the “Broken Heart”
Authors: Novak Gregg , Kross Kimberly , Follmer Kristy , Brofferio Alessandra , Shirani Jamshid
Published: August 2007

Transient left ventricular (LV) apical ballooning and normal epicardial coronary arteries are the hallmarks of Takotsubo cardiomyopathy. The syndrome is often triggered by emotional or physiologic stress, and its pathogenesis is poorly understood. Current proposals focus on elevated cathecolamines in association with abnormal coronary artery endothelium, coronary microcirculation or LV geometry. Right ventricular (RV) involvement, as described in our patient, is not reported as a typical feature. Presence of RV dysfunction may affect the initial management of these patients and raises questions regarding the universal applicability of the currently proposed pathophysiologic mechanisms of this syndrome.

Clinical Implications of Precordial ST‐segment Elevation in Acute Inferoposterior Myocardial Infarction Caused by Proximal Right Coronary Artery Occlusion
Authors: Jim Man‐Hong , On‐On Chan Annie , Wong Chun‐Pong , Yiu Kai‐Hang , Miu Raymond , Wai‐Luen Lee Stephen , Lau M.D. Chu‐Pak
Published: August 2007

Background

The clinical significance of inferior wall acute myocardial infarction (MI) with combined ST‐segment elevation in both anterior and inferior leads, compared with inferior leads alone, is unknown.

Hypothesis

Despite having more leads with precordial ST‐segment elevation, these patients may have a better outcome due to less posterior involvement, which tends to drag down the precordial ST‐segment.

Methods

A total of 158 postinferior MI patients with documented proximal right coronary artery occlusion were retrospectively studied. They were divided into three subgroups according to the magnitude of concurrent ST‐segment deviation in lead V2: Group A (n = 19) had ST‐segment elevation ≥ 2.0 mm; Group B (n = 74) had ST‐segment lay between + 2.0 mm and − 2.0 mm; and Group C (n = 65) had ST‐segment depression ≥ 2.0 mm. The clinical and electrocardiographic characteristics were then compared among these threes subgroups.

Results

The baseline demography, prevalence of risk factors, and treatment received were of no difference among the subgroups. However, Group A patients had significantly lower peak creatinine phosphokinase level and more preserved left ventricular function than Group B and C. Moreover, they had lower total sum of inferior ST‐segment magnitude, less ST‐segment depression in V4‐6, and more ST‐segment elevation in V4R than Group C. Group C patients had highest in‐hospital and one‐year mortality although it did not reach statistical significance.

Conclusions

Precordial ST‐segment elevation in inferior wall acute MI was associated with smaller infarct size and better left ventricular function, probably secondary to occlusion of a less dominant RCA, which did not result in a significant posterior infarction. Copyright © 2007 Wiley Periodicals, Inc.

These automated systems are capable of generating significantly more data within the same amount of time compared to their manual counterparts. Automatically capturing and recording data provenance and annotation as part of these workflows are critical for data management, verification, and dissemination. We have been prototyping a workflow provenance system, targeted at biological workflows, that extends our content management technologies and other open source tools. We applied this prototype to the provenance challenge to demonstrate an end‐to‐end system that supports dynamic provenance capture, persistent content management, and dynamic searches of both provenance and metadata. We describe our prototype, which extends the Kepler system for the execution environment, the Scientific Annotation Middleware (SAM) content management software for data services, and an existing HTTP‐based query protocol. Our implementation offers several unique capabilities, and through the use of standards, is able to provide access to the provenance record with a variety of commonly available client tools.

The Eph and ephrin families are involved in numerous developmental processes. Recently, an increasing body of evidence has related these families with some aspects of T cell development. In the present study, we show that the addition of either EphB2‐Fc or ephrinB1‐Fc fusion proteins to fetal thymus organ cultures established from 17‐day‐old fetal mice decreases the numbers of both double‐positive (CD4+CD8+) and single‐positive (both CD4+CD8– and CD4–CD8+) thymocytes, in correlation with increased apoptosis. By using reaggregate thymus organ cultures formed by fetal thymic epithelial cells (TEC) and CD4+CD8+ thymocytes, we have also demonstrated that ephrinB1‐Fc proteins are able to disorganize the three‐dimensional epithelial network that in vivo supports the T cell maturation, and to alter the thymocyte interactions. In addition, in an in vitro model, Eph/ephrinB‐Fc treatment also decreases the formation of cell conjugates by CD4+CD8+ thymocytes and TEC as well as the TCR‐dependent signaling between both cell types. Finally, immobilized EphB2‐Fc and ephrinB1‐Fc modulate the anti‐CD3 antibody‐induced apoptosis of CD4+CD8+ thymocytes in a process dependent on concentration. These results therefore support a role for Eph/ephrinB in the processes of development and selection of thymocytes as well as in the establishment of the three‐dimensional organization of TEC.
Immune mechanisms leading to abnormal B cell selection and activation in New Zealand Black mice

Published: August 2007

Polyclonal B cell activation is a hallmark of the immune dysregulation in New Zealand Black (NZB) mice. We have previously shown that the splenic B cell activation is associated with increased CD80 expression. Here we show that abnormal expansions of CD80‐expressing GC, CD5+, marginal zone (MZ) precursor and MZ B cells produce this increase. To investigate the role of BCR engagement in the generation and activation of these populations, a non‐self‐reactive Ig Tg was introduced onto the NZB background. NZB Ig‐Tg mice lacked Tg CD5+ and peanut agglutinin+ B cells, confirming the role of endogenous Ag in their selection. Although the increased proportion of MZ B cells was retained in NZB Ig‐Tg mice, CD80 expression on these cells was reduced as compared to non‐Tg NZB mice, suggesting a role for BCR engagement with endogenous Ag in their activation. Examination of CD40L‐knockout NZB mice showed no difference in the abnormal activation or selection of the B cell populations, with the exception of GC cells, as compared to wild‐type NZB mice. Thus, polyclonal B cell activation in NZB mice does not require CD40 engagement, but results, in part, from dysregulated BCR‐specific mechanisms.
Square‐Wave Voltammetric Determination of Paraquat at Carbon Paste Electrode Modified with Hydroxyapatite
Authors: El Mhammedi Moulay Abderrahim , Bakasse Mina , Chtaini Abdelilah
Published: August 2007

The voltammetric behavior of paraquat was investigated at hydroxyapatite‐modified carbon paste electrode HAP‐CPE in K2SO4. A method was developed for the detection of the trace of this herbicide, based on their redox reaction. The reduction peaks of paraquat were observed around −0.70 V and −1.00 V (vs. SCE) in square‐wave voltammetry. Experimental conditions were optimized by varying the accumulation time, apatite loading and measuring solution pH. Calibration plots were linear under the optimized parameters over the herbicide's concentration range 8–200×10−7 mol L−1, with a detection and quantification limits about 1.5×10−8 mol L−1 and 6.4 10−8 mol L−1, respectively.
Fitting negative spatial covariances to geothermal field temperatures in Nea Kessani (Greece)
Authors: Mateu Jorge , Porcu Emilio , Christakos George , Bevilacqua Moreno
Published: August 2007

In this paper, we investigate the problem of negative empirical covariances for temperature data in a three‐dimensional geothermal field. We make use of permissibility criteria that allow a linear combination of covariance functions to be positive definite even if some of the weights of the linear combination are set to be negative. We thus propose a generalized sum of spatial covariance structures to model negative spatial covariances. We evaluate the performance of the proposed model, together with that of other celebrated, and widely used covariance functions. Comparison is done in terms of cross‐validation, which allows to evaluate the relative bias, accuracy of estimation, and goodness‐of‐fit. Copyright © 2007 John Wiley & Sons, Ltd.
Prediction of the force–drift envelope for RC columns in flexure by the CAE method
Authors: Peruš Iztok , Fajfar Peter
Published: August 2007

A non‐parametric empirical approach, called the conditional average estimator (CAE) method, has been applied for the prediction of the normalized lateral force–drift envelope of reinforced concrete (RC) rectangular columns, as well as their characteristic drifts (effective yield drift, capping drift and ultimate drift), and drift‐related parameters (the ratio between the effective yield drift and elastic drift, and two ductility measures). A subset of the PEER RC column database was used. Five input parameters were employed: axial load index, index related to confinement, shear span index, concrete compressive strength, and longitudinal reinforcement index. The results suggest that the relations between the input and output parameters are complex, and that it is difficult to isolate the influence of a single parameter. Nevertheless, some trends were observed. The axial load index is the most influential input parameter. All the results decrease with an increasing axial load index, whereas they increase with an increasing longitudinal
reinforcement index. An increase in the index related to confinement results in increases in the ultimate drift and in ductility. The influence of the shear span index is the most complex. The influence of the concrete strength is small with the exception of two output parameters related to elastic drift, which substantially decrease with increasing strength. The dispersion of the results is relatively large. The results of the predictions can be used for mathematical modelling of moment–rotation backbone curves for plastic hinges, and for the estimation of the deformation capacity of columns in seismic performance assessments.

Published: August 2007

Whole genome scanning of 43 lung cancer cell lines at a 100‐kb resolution led to identification of 51 genomic regions with homozygous deletions (HDs). The regions contained 113 genes, including two known tumor suppressor genes, RBl (RB) and CDKN2A (p16), and eight genes previously reported as being candidate tumor suppressor genes, such as PTPRD and LRP1B. Three miRNA genes, MIRNLET7C (let‐7c), MIRN99A (hsa‐mir‐99a), and MIRN125B2 (hsa‐mir‐125b‐2), were also mapped in a region with HD at 21q11‐q21. The present study provides a list of protein‐ and miRNA‐encoding genes whose inactivation is possibly involved in lung carcinogenesis. © 2007 Wiley‐Liss, Inc.
Altering DNA base excision repair: Use of nuclear and mitochondrial‐targeted N‐methylpurine DNA glycosylase to sensitize astroglia to chemotherapeutic agents

Published: August 2007

Primary astrocyte cultures were used to investigate the modulation of DNA repair as a tool for sensitizing astrocytes to genotoxic agents. Base excision repair (BER) is the principal mechanism by which mammalian cells repair alkylation damage to DNA and involves the processing of relatively nontoxic DNA adducts through a series of cytotoxic intermediates during the course of restoring normal DNA integrity. An adenoviral expression system was employed to target high levels of the BER pathway initiator, N‐methylpurine glycosylase (MPG), to either the mitochondria or nucleus of primary astrocytes to test the hypothesis that an alteration in BER results in increased alkylation sensitivity. Increasing MPG activity significantly increased BER kinetics in both the mitochondria and nuclei. Although modulating MPG activity in mitochondria appeared to have little effect on alkylation sensitivity, increased nuclear MPG activity resulted in cell death in astrocyte cultures treated with methylnitrosourea (MNU). Caspase‐3 cleavage was not detected, thus indicating that these alkylation sensitive astrocytes do not undergo a typical programmed cell death in response to MNU. Astrocytes were found to express relatively high levels of antiapoptotic Bcl‐2 and Bcl‐XL and very low levels of proapoptotic Bad and Bid suggesting that the mitochondrial pathway of apoptosis may be blocked making astrocytes less vulnerable to proapoptotic stimuli compared with other cell types. Consequently, this unique characteristic of astrocytes may be responsible, in part, for resistance of astrocytomas to chemotherapeutic agents. © 2007 Wiley‐Liss, Inc.
Task and semantic relationship influence both the polarity and localization of hemodynamic modulation during lexico‐semantic processing
Authors: Kuperberg Gina R. , Lakshmanan Balaji M. , Greve Douglas N. , West W. Caroline
Published: August 2007

This study examined how task (implicit vs. explicit) and semantic relationship (direct vs. indirect) modulated hemodynamic activity during lexico‐semantic processing. Participants viewed directly related, indirectly related, and unrelated prime‐target word‐pairs as they performed (a) an implicit lexical decision (LD) task in which they decided whether each target was a real word or a nonword, and (b) an explicit relatedness judgment (RJ) task in which they determined whether each word‐pair was related or unrelated in meaning. Task influenced both the polarity and neuroanatomical localization of hemodynamic modulation. Semantic relationship influenced the neuroanatomical localization of hemodynamic modulation. The implicit LD task was primarily associated with inferior prefrontal and ventral inferior temporal/fusiform hemodynamic response suppression to directly related (relative to unrelated) word‐pairs, and with more widespread temporal–occipital response suppression to indirectly related (relative to unrelated) word‐pairs. In contrast, the explicit RJ task was primarily associated with left inferior parietal hemodynamic response enhancement to both directly and indirectly related (relative to unrelated) word‐pairs, as well as with additional left inferior prefrontal hemodynamic response enhancement to indirectly related (relative to unrelated) word‐pairs. These findings are discussed in relation to the specific neurocognitive processes thought to underlie implicit and explicit semantic processes. Hum Brain Mapp, 2008. © 2007 Wiley‐Liss, Inc.
Increased neural efficiency in the temporal association cortex as the result of semantic task repetition
Authors: Whatmough Christine , Nikelski Jim , Monchi Oury , Chertkow Howard
Published: August 2007

We examined the effect of semantic task repetition and of alternating between tasks on cerebral blood flow in three H215O positron emission tomography experiments. We found that repeatedly performing semantic tasks resulted in a reduction in cerebral blood flow to the left temporal association cortex similar to that found in priming experiments even though here there was no repetition of stimuli. Although the same effect was found in two different tasks (word meaning judgments and picture naming), it was only present when the same task was repeated on consecutive scans and not when the subjects alternated from scan to scan between tasks. We propose that there is a neural efficiency which develops in the association cortex of the temporal lobe as a result of repeatedly performing a semantic task. This efficiency is abolished by interruptions such as performing a different task. Hum Brain Mapp, 2008. © 2007 Wiley‐Liss, Inc.
Identification of a novel class of dithiolethiones that prevent hepatic insulin resistance via the adenosine monophosphate–activated protein kinase–p70 ribosomal S6 kinase-1 pathway
Authors: Bae Eun Ju , Yang Yoon Mee , Kim Jin Wan , Kim Sang Geon
Published: August 2007

Several established liver diseases of various causes are highly associated with hepatic insulin resistance, which is characterized by the desensitization of target cells to insulin. Peripheral insulin resistance is observed in most patients who have cirrhosis. Conversely, insulin-resistant diabetic patients are at increased risk for developing liver disease. Current therapeutic interventions in insulin resistance are limited and therefore likely to be advanced by new tailor-made drugs. Oltipraz, a prototype dithiolthione, inhibits transforming growth factor β1 and has the ability to regenerate cirrhotic liver. We investigated the effects of oltipraz and synthetic dithiolthiones on hepatic insulin resistance and the molecular basis of action. Oltipraz and other dithiolethione compounds were tested on tumor necrosis factor α (TNF-α)–induced insulin resistance and glucose homeostasis

in vitro

and

in vivo

via immunoblotting, plasmid transfection, kinase analysis, and functional assays. Oltipraz treatment inhibited the ability of TNF-α to activate p70 ribosomal S6 kinase-1 (S6K1) downstream of mammalian target of rapamycin, thus preventing insulin receptor substrate-1 serine phosphorylation and protecting insulin signals. Moreover, oltipraz activated AMP-activated protein kinase (AMPK), whose inhibition by a dominant negative mutant abolished S6K1 inhibition and protected insulin signaling, indicating that AMPK activation leads to S6K1 inhibition. In hepatocyte-derived cell lines, oltipraz inhibited glucose production. Oltipraz prevented hepatic insulin resistance in C57BL/6 mice challenged with endotoxin (or TNF-α), leptin-deficient mice, and mice fed a high-fat diet. Synthetic dithiolethiones comparably inhibited insulin resistance.

Conclusion:

Our findings led to the identification of dithiolethione compounds that prevent insulin resistance through a mechanism involving AMPK-mediated S6K1 inhibition and thereby sensitize hepatic insulin response. (Hepatology 2007.)
