Coronary Flow Slows as Renal Function Worsens
Authors: Yilmaz Mehmet Birhan , Yalta Kenan
Published: May 2009

Background

Slow coronary flow in patients without obstructive coronary artery disease is an angiographic finding that could easily be detected by thrombolysis in myocardial infarction (TIMI) frame counts. On the other hand, impaired renal function is a frequent problem. We searched the association between the 2 entities.

Hypothesis

We evaluated the impact of impaired renal function on slow coronary flow.

Methods

In this study, 105 patients with normal coronary arteries and impaired renal function in the form of a calculated glomerular filtration rate (GFR) < 90 mL/min/1.73 m2 were enrolled and compared with 102 age‐ and sex‐matched controls who had normal a GFR.

Results

Calculated GFR was found to be negatively correlated with TIMI frame count in LAD (r = − 0.579, p < 0.001), in CX (r = − 0.499, p < 0.001), and in RCA (r = − 0.491, p < 0.001) in patients with impaired renal function. After adjusting for systolic and diastolic blood pressure and high‐density lipoprotein (HDL) cholesterol, multiple regression analysis demonstrated a statistically significant and independent relationship between TIMI frame count for 3 vessels and calculated GFR.

Conclusions

Impaired renal function seems to denote slower coronary flow in patients with normal coronary arteries compared with those with normal renal function, and there seems to be an independent association between GFR and TIMI frame count in those with impaired renal function.

Published: May 2009

Fibroblasts regulate their contractile force in response to external stretch; however, the detailed mechanism by which the force is regulated is unclear. Here, we show that diphosphorylation and dephosphorylation of myosin regulatory light chain (MRLC) are involved in the stretch‐induced force response. Cellular stiffness, which reflects the cellular contractile force, under external stretch was measured by mechanical‐scanning probe microscopy. Fibroblasts (NIH‐3T3) expressing green fluorescent protein (GFP)‐tagged mutant‐type MRLC (MRLCT18A‐GFP), which cannot be diphosphorylated, did not show any stretch‐induced stiffness response, whereas the stiffness in cells expressing GFP‐tagged wild‐type MRLC (MRLCWT‐GFP) increased immediately after the stretch and subsequently decreased after 1–2 h. Urea‐PAGE western blot analysis showed that the proportion of diphosphorylated MRLC (PP‐MRLC) transiently increased after the stretch and decreased after 1–2 h. Dominant‐negative RhoA (RhoAN19)‐expressing cells did not show the stiffness response to the stretch, whereas wild‐type RhoA‐expressing cells did. It was concluded that the cellular force response originates in the stretch‐induced diphosphorylation and dephosphorylation of MRLC and is regulated via the RhoA signaling cascade Cell Motil.

Optimizing multiple conjugate gradient solvers for large‐scale systems
Authors: Sancho Jose Carlos , Kerbyson Darren J.
Published: May 2009

Conjugate gradient (CG) solvers are the most time consuming part of many scientific applications. These solvers exhibit communication operations that can prevent high performance from being achieved on large‐scale systems. In this paper we present a novel technique to boost the performance of these solvers. In this, multiple independent solvers, which occur in some applications, are combined allowing for the overlapping of communication with other communication and computation, resulting with increased performance. This is the first work where a combination of CG solvers has been exploited and offers performance improvements, which may be particularly important in very large‐scale systems. Results are presented for the MIMD lattice computation (MILC) application that show the cost of collective communications can be reduced by a factor of up to 2.5×. Moreover the performance of MILC is significantly improved, by over 10% for typical lattice sizes on a 1024‐processor system, and by 15% on a 4096‐processor system. Larger improvements are expected on larger systems. Copyright © 2009 John Wiley & Sons, Ltd.
Glucose abnormalities in non‐alcoholic fatty liver disease and chronic hepatitis C virus infection: the role of iron overload
Authors: Lecube Albert , Hernández Cristina , Simó Rafael
Published: May 2009

Non‐alcoholic fatty liver disease (NAFLD) and chronic hepatitis C virus (HCV) infection are major causes of liver disease frequently described in outpatient patients with glucose abnormalities. Hyperferritinemia, which suggests that iron overload plays a decisive role in the pathophysiology of insulin resistance and hyperglycemia, is a common finding in both disorders. However, the role of the hepatic iron deposition differs from one to the other. In NAFLD, a moderate liver iron accumulation has been observed and molecular mechanisms, including the downregulation of the liver iron exporter ferroportin‐1, have been described. Iron overload will enhance intrahepatic oxidative stress that promotes hepatic fibrosis, interfere with insulin signalling at various levels and may hamper hepatic insulin extraction. Therefore, liver fibrosis, hyperglycemia and hyperinsulinemia will lead to increased levels of insulin resistance and the development of glucose abnormalities. Furthermore, iron depletion by phlebotomy removes liver iron content and reduces serum glucose and insulin resistance in NAFLD patients. Therefore, it seems that iron overload participates in those glucose abnormalities associated with NAFLD. Concerning chronic HCV infection, it has been classically assumed that iron overload contributes to insulin resistance associated with virus infection. However, recent evidence argues against the presence of iron overload in these patients and points to inflammation associated with diabetes as the main contributor to the elevated ferritin levels. Therefore, glucose abnormalities, and specially type 2 diabetes, should be taken into account when evaluating serum ferritin levels in patients with HCV infection.

Syntheses, Crystal Structures and Adsorption Properties of Ultramicroporous Coordination Polymers Constructed from Hexafluorosilicate Ions and Pyrazine (Eur. J. Inorg. Chem. 16/2009)

Published: May 2009

The cover picture The cover picture shows two crystal structures of porous coordination polymers, [Cu(SiF6)(4,4′bpy)2]n and [Zn(SiF6)(pyz)2]n (4,4′‐bpy = 4,4′‐bipyridine, pyz = pyrazine), which have been generated from square‐grid coordination polymers that are cross‐linked by ν‐SiF6 anions. Although typical bridging ligands such as 4,4′‐bpy and 1,4‐benzenedicarboxylate produce open octahedral coordination polymers with micropores, such micropores need to be further narrowed to become ultramicropores (< 7 Å) for separation and purification of smaller gas molecules. We have succeeded in obtaining the ultramicroporous coordination polymer [Zn(SiF6)(pyz)2]n with 4.5 ± 4.5 Å2 pores by simply replacing 4,4′‐bpy in [M(SiF6)(4,4′‐bpy)2]n (M = Zn2+, Cu2+) with pyz. The ultramicropores of [Zn(SiF6)(pyz)2]n adsorb Me2CO rather than iPrOH, showing the size‐exclusive effect. Additionally this compound shows a sharp uptake in H2 adsorption at 77 K, because the interaction potential is expected to be strong as a result of the synergistic effect of the neighbouring pore walls. Details are discussed in the article by K. Uemura et al. on p. 2329 ff.
Gold(I) Catalysis: Selective Synthesis of Six‐ or Seven‐Membered Heterocycles from Epoxy Alkynes
Authors: Dai Lun‐Zhi , Shi Min
Published: May 2009

Gold(I)‐catalyzed intramolecular cycloisomerization of ketone‐substituted epoxides with alkynes to six‐ or seven‐membered heterocyclic compounds is firstly introduced in this paper. This procedure involves a cascade isomerization of the ketone‐substituted epoxides into 1,3‐diketones in the presence of a Lewis acid and subsequent gold(I)‐catalyzed selective intramolecular addition of an oxygen or a carbon nucleophile to the alkynes.

Short Access to the Aromadendrane Family: Highly Efficient Stereocontrolled Total Synthesis of (±)‐Cyclocolorenone and (±)‐α‐Gurjunene
Authors: Calancea Mihaela , Carret Sébastien , Deprés Jean‐Pierre
Published: May 2009

(±)‐Cyclocolorenone (2), an aromadendrane, was prepared stereoselectively in seven steps in 10.8–12.5 % overall yield from the commercially available tropylium cation via key intermediate 6, which was used as a general and efficient precursor to bicyclo[5.3.0]decane sesquiterpenes. (±)‐α‐Gurjunene (3) was obtained through the efficient deoxygenation of (±)‐2, constituting therefore the first total synthesis of this natural product in eight steps from the tropylium cation.

Alkyne Hydroarylations with Chelating Dicarbene Palladium(II) Complex Catalysts: Improved and Unexpected Reactivity Patterns Disclosed Upon Additive Screening
Authors: Biffis Andrea , Gazzola Luca , Gobbo Pierangelo , Buscemi Gabriella , Tubaro Cristina , Basato Marino
Published: May 2009

Palladium(II) complexes with a ligand set made from a chelating N‐heterocyclic dicarbene ligand and two weakly coordinating anions (generally introduced in situ upon addition of 2 equiv. of a suitable silver salt) were found to be very active and selective catalysts for the room‐temperature hydroarylation of alkynes at low catalyst loading (0.1 mol‐%). Moreover, the screening of various strong acids as reaction promoters revealed that both the strength of the acid and the coordinating ability of its conjugated base influence the catalytic performance. Most remarkably, the use of HBF4 together with a dicarbene Pd complex catalyst provides a dramatic change in the selectivity of the reaction, with the prevalent formation of a product stemming from the insertion of two molecules of alkyne into the aromatic C–H bond. The results presented herein highlight the fact that the dicarbene ligand, apart from stabilising the catalyst, is also able to enhance catalytic activity and, most notably, to steer the reaction selectivity towards novel products.

The links between the categorised Southern Oscillation indicators and climate and hydrologic variables in Turkey
Authors: Karabörk M. Çaǧatay , Kahya Ercan
Published: May 2009

Some previous global and regional studies have indicated teleconnection between the extreme phases of the Southern Oscillation (SO) and Turkish climate and hydrologic variables; however, they failed to suggest a strong correlation structure. In this study, categorised Southern Oscillation index (SOI) and Multivariate ENSO (El Nino Southern Oscillation) index (MEI) series were used to examine the far‐reaching effects of the SO on temperature, precipitation and streamflow patterns in Turkey. These SO indicators were categorised into five subgroups according to their empirical distributions. Correlations between the categorised SO indicators and three analysis variables were computed using the Spearman's rho from lag‐0 to lag‐4. Significance of calculated correlations was tested at the 0·01 level for station‐based analysis and at the 0·05 level for regional analysis. Temperature records demonstrated significant correlations with the categorised SOI and MEI in nearly half of the entire stations. For some categories, precipitation and streamflow were found to be correlated with the SO indicators in some stations mainly in western Turkey. Regional analyses of temperature and precipitation revealed a clear and strong correlation structure with the categorised SO indicators on a large portion of Turkey. This was not concluded by the earlier pertinent studies. Besides, this study showed that significant correlations were obtained not only for the SO extreme phases (namely, El Nino and La Nina) but also for neutral and moderate phases of the SO. Plausible explanations for the observed teleconnection are presented. Copyright © 2009 John Wiley & Sons, Ltd.
Silver ion‐induced suicidal erythrocyte death
Authors: Sopjani Mentor , Föller Michael , Haendeler Judith , Götz Friedrich , Lang Florian
Published: May 2009

Owing to its antibiotic activity, silver is used for water purification, wound care and a wide variety of implants. Silver metal and silver compounds ionize in solution, and silver ions interfere with the function of a wide variety of proteins. In mammalian cells, silver ions may trigger apoptosis by stimulation of cytochrome c release from mitochondria. The present study explored the effect of AgNO3 on eryptosis, the suicidal death of erythrocytes, cells devoid of mitochondria. Similar to apoptosis of nucleated cells, eryptosis is characterized by cell shrinkage and cell membrane scrambling with phosphatidylserine exposure at the cell surface. Eryptosis is triggered by energy depletion, cellular depletion of nitric oxide (NO) and activation of protein kinase C (PKC). Phosphatidylserine exposure was determined by annexin V‐binding, cell volume by forward scatter, cellular ATP by a luciferin–luciferase assay kit, and hemolysis by photometry. A 48 h exposure to AgNO3 (≥100 nm) but not to NaNO3 significantly enhanced the percentage of annexin V‐binding cells, slightly but significantly decreased forward scatter and significantly decreased cytosolic ATP. Furthermore, inhibition of PKC by staurosporine and donation of NO by sodium nitroprusside significantly blunted silver‐induced eryptosis. In conclusion, AgNO3 triggers cell membrane scrambling, an effect attributed to ATP depletion, PKC activation and decrease of cellular NO. Copyright © 2009 John Wiley & Sons, Ltd.

Published: May 2009

cDNA micorarray approach was applied to hepatic transcriptional profile analysis in male mouse (Mus musculus, ICR) to assess the potential health effects of drinking water in Nanjing, China. Mice were treated with continuous exposure to drinking water for 90 days. Hepatic gene expression was analyzed with Affymetrix Mouse Genome 430A 2.0 arrays, and pathway analysis was carried out by Molecule Annotation System 2.0 and KEGG pathway database. A total of 836 genes were found to be significantly altered (1.5‐fold, P ≤ 0.05), including 294 up‐regulated genes and 542 down‐regulated genes. According to biological pathway analysis, drinking water exposure resulted in aberration of gene expression and biological pathways linked to xenobiotic metabolism, signal transduction, cell cycle and oxidative stress response. Further, deregulation of several genes associated with carcinogenesis or tumor progression including Ccnd1, Egfr, Map2k3, Mcm2, Orc2l and Smad2 was observed. Although transcription changes in identified genes are unlikely to be used as a sole indicator of adverse health effects, the results of this study could enhance our understanding of early toxic effects of drinking water exposure and support future studies on drinking water safety.

CHARMM (Chemistry at HARvard Molecular Mechanics) is a highly versatile and widely used molecular simulation program. It has been developed over the last three decades with a primary focus on molecules of biological interest, including proteins, peptides, lipids, nucleic acids, carbohydrates, and small molecule ligands, as they occur in solution, crystals, and membrane environments. For the study of such systems, the program provides a large suite of computational tools that include numerous conformational and path sampling methods, free energy estimators, molecular minimization, dynamics, and analysis techniques, and model‐building capabilities. The CHARMM program is applicable to problems involving a much broader class of many‐particle systems. Calculations with CHARMM can be performed using a number of different energy functions and models, from mixed quantum mechanical‐molecular mechanical force fields, to all‐atom classical potential energy functions with explicit solvent and various boundary conditions, to implicit solvent and membrane models. The program has been ported to numerous platforms in both serial and parallel architectures. This article provides an overview of the program as it exists today with an emphasis on developments since the publication of the original CHARMM article in 1983. © 2009 Wiley Periodicals, Inc.J Comput Chem, 2009.
