Interpersonal contribution to outcome: the relation of interpersonal distress and symptomatic improvement as a result of psychotherapy
Authors: Hardy Amanda O. , Tracey Terence J. G. , Glidden‐Tracey Cynthia , Hess Timothy R. , Rohlfing Jessica E. 
Published: June 2010

AbstractThe study utilized a 32‐item brief measure of interpersonal problems (IIP) to examine interpersonal distress in relation to symptomology and treatment outcome as assessed by the Outcome Questionnaire‐45 (OQ‐45). The study included a community sample of 210 individuals receiving psychotherapy at a mental health training facility. A number of significant correlations were found between interpersonal distresses with symptomology. The highest correlations were found between levels of general interpersonal distress and symptoms relating to psychiatric and social distress at the onset of therapy; in general the IIP did not differentiate between symptomology types. The study failed to replicate previous research indicating a relation between facets of interpersonal problems with treatment outcome. Copyright © 2010 John Wiley & Sons, Ltd.Key Practitioner Message:• Evidence is provided for the use of a brief measure of interpersonal problems (IIP‐32) as a valid alternative to lengthier versions in a clinical setting.• Interpersonal problems are associated with various facets of clinical symptomology but do little to differentiate between symptomology types.• Reported rates of general interpersonal distress at the onset of therapy differ among clients that do and do not make clinically significant changes in areas of overall symptomology and interpersonal difficulties.

A simplified pricing model for volatility futures
Authors: Dupoyet Brice , Daigler Robert T. , Chen Zhiyao 
Published: June 2010

AbstractWe develop a general model to price VIX futures contracts. The model is adapted to test both the constant elasticity of variance (CEV) and the Cox–Ingersoll–Ross formulations, with and without jumps. Empirical tests on VIX futures prices provide out‐of‐sample estimates within 2% of the actual futures price for almost all futures maturities. We show that although jumps are present in the data, the models with jumps do not typically outperform the others; in particular, we demonstrate the important benefits of the CEV feature in pricing futures contracts. We conclude by examining errors in the model relative to the VIX characteristics. © 2010 Wiley Periodicals, Inc. Jrl Fut Mark 31:307–339, 2011

AbstractFucan is a term used to denominate a family of sulfated polysaccharides rich in L‐fucose. They are extracted mainly from brown seaweeds and echinoderms. The brown seaweed Spatoglossum schröederi (Dictyotaceae) synthesizes three heterofucans named A, B and C. Our research group purified a non‐anticoagulant heterofucan (fucan A) which displays antithrombotic activity in vivo. However, its in vitro toxicity has yet to be determined. This work presents the evaluation of the potential cytotoxicity, mutagenicity and genotoxicity of this fucan. After 48 h incubation fucan A cytotoxicity was determinate using MTT assay. Tumor‐cell (HeLa, PC3, PANC, HL60) proliferation was inhibited 2.0–43.7%; at 0.05–1 mg ml−1 of the heterofucan, the 3T3 non‐tumor cell line proliferation was also inhibited (3.3–22.0%). On the other hand, the CHO tumorigenic and RAW non‐tumor cell lines proliferation were not affected by this molecule (0.05–1 mg ml−1). We observed no mutagenic activity in Salmonella reversion assay when bacterial strains TA97a, TA98, TA100 and TA102 (with and without S9) were used. Comet assay showed that fucan A had no genotoxic effect (from 20 to 1000 µg ml−1) on CHO cells. In conclusion, this study indicates that the S. schröederi fucan A was not found to be genotoxic or mutagenic compound; thus it could be used in new antithrombotic drug development.

Separation of flavonoid and alkaloid using collagen fiber adsorbent
Authors: Li Juan , Liao Xuepin , Liao Guanhao , He Qiang , Zhang Wenhua , Shi Bi 
Published: June 2010

AbstractFlavonoids and alkaloids are two major classes of plant compounds with biological activities, and they usually coexist in many medicinal herbs. In this study, a novel collagen fiber adsorbent (CFA) was prepared, and its application for adsorption chromatography separation of flavonoids and alkaloids was systematically investigated. The typical flavonoids, rutin and baicalin, and the typical alkaloids, matrine and caffeine, were selected as probe molecules for the investigations. The batch adsorption behaviors of these compounds on CFA in different solvents indicated that hydrogen bond plays a predominant role for the adsorption of flavonoid and alkaloid in pure ethanol, while the hydrophobic interaction plays a predominant role for the adsorption in water. In column chromatography separation, flavonoids were completely separated from alkaloids by a stepwise elution process with pure ethanol followed by aqueous ethanol solution. The two flavonoids, rutin and baicalin, were also well separated although the two alkaloids, matrine and caffeine, were washed out together. The optimal loading volume of sample solution (10 mg/mL) for the separation was determined as 0.66 mL/g CFA. Under these conditions, flavonoid and alkaloid were effectively separated with a recovery higher than 90% in 8 times repeated applications.
A simple methodology for the determination of fatty acid composition in edible oils through 1H NMR spectroscopy
Authors: Barison Andersson , Pereira da Silva Caroline Werner , Campos Francinete Ramos , Simonelli Fabio , Lenz Cesar Antonio , Ferreira Antonio Gilberto 
Published: June 2010

AbstractA simple methodology for the determination of the fatty acid composition of edible oils through 1H NMR is proposed. The method is based on the fact that all fatty acid chains are esterified to a common moiety, glycerol, and the quantification is done directly in the 1H NMR spectra through the relationship between the areas of a characteristic signal of each fatty acid and a signal of the glycerol moiety, without the use of mathematical equations. The methodology was successfully applied to determine the fatty acid composition of several edible oils, with equivalent results to those given by the AOAC Official method by gas chromatography. Its main advantages are simplicity and the lack of need for sample pre‐treatment such as derivatization or extraction. Copyright © 2010 John Wiley & Sons, Ltd.
Intraoperative on‐nerve nerve conduction study and conversion factor in the sural nerve
Authors: Oh Shin J. , Hemmi Shoji , Kurokawa Katsumi , Hatanaka Yuki 
Published: June 2010

AbstractTo determine the conversion factor (CF) of the sural nerve the correlation between the maximum nerve conduction velocity (NCV) and the diameter of the largest fibers was studied in 30 patients suspected of having neuropathy. Sensory nerve action potentials were obtained by on‐nerve needle nerve conduction study using needle electrodes placed on the exposed sural nerve during biopsy. The CF was 4.3 (n = 2) in normal sural nerves and close to the normal value (3.85, n = 4) in axonal neuropathy. The CF in demyelinating neuropathy was smaller than the normal value (2.77, n = 24), indicating disproportionately slower conduction than expected from the diameter of nerve fibers. The CF was helpful in differentiating between demyelinating and axonal neuropathies. We propose that a 36% decrease from the mean value of NCV is a reasonable criterion for demyelination of the nerve. Muscle Nerve, 2010

AbstractBackgroundHigh dosage anthracyclines in pediatric patients with acute lymphoblastic leukemia (ALL) is associated with cardiotoxicity. However, data on the cardiac effects of lower cumulative doses of these drugs are not conclusive. The aim of this study was to assess the cardiac effects of low cumulative anthracycline doses in long‐term survivors of ALL.ProcedureEchocardiograms were performed on 62 long‐term ALL survivors, without any overt or sub‐clinical signs or symptoms of heart failure. The interval after stopping therapy was 12.6 ± 4.3 years; the mean cumulative dose of anthracyclines was 228.2 ± 42.3 mg/m2. Left ventricular (LV) structure and function were studied by echocolor‐Doppler. An age, gender and body surface area (BSA) matched group of healthy subjects was used as controls. Cardiac data were analyzed before and after BSA normalization.ResultsLong term survivors of ALL, showed a lower LV mass index, interventricular septal and posterior wall thickness, which were independently related to gender and to age at which the ALL diagnosis was made. Data analyzed according to gender showed that abnormalities were confined to the female group. No alterations were observed in the ALL male group versus the corresponding control group. No relationship was observed between the echocardiografic abnormalities and the duration of follow‐up or the anthracycline mean dose employed.ConclusionsIn the absence of any signs or symptoms of heart failure, female ALL survivors treated with low cumulative anthracycline doses, showed a reduced LV mass and wall thickness. This suggests that in female ALL survivors an echocardyographic follow‐up should be recommended. Pediatr Blood Cancer. 2010;55:1343–1347. © 2010 Wiley‐Liss, Inc.

AbstractThe mode of binding of interleukin‐4 (IL‐4) to its two known receptors, specific receptor IL‐4R and a shared receptor γc, was investigated using gel filtration and gel electrophoresis. A ternary complex between IL‐4 and the soluble domains of the two receptors was shown to exist in solution. The association constant between γc and the stable complex of IL‐4/sIL‐4R is in the millimolar range, making the ternary complex a feasible target for crystallization studies.
Structures of partridge egg‐white lysozyme with and without tri‐N‐acetylchitotriose inhibitor at 1.9 Å resolution
Authors: Turner M. A. , Howell P. L. 
Published: June 2010

AbstractThe three‐dimensional structures of native partridge egg‐white lysozyme (PEWL) and PEWL complexed with tri‐N‐acetylchitotriose inhibitor have been determined crystallographically and refined at 1.9 Å resolution. Crystals of native and complexed protein are isomorphous and have space group and cell dimensions that are identical to those of hen egg‐white lysozyme (HEWL) under similar crystallization conditions. Full occupancy of the trisac‐charide in the inhibitor complex has allowed definitive modeling and refinement of all three sugar residues, located at subsites A, B, and C in the PEWL active site. A comparison has been made with HEWL/inhibitor complexes in which coordinates were either not refined (Blake CCF, et al., 1967, Proc R Soc B 167:378–388) or were refined at partial occupancy (Cheetham JC, Artymiuk PJ, Phillips DC, 1992, J Mol Biol 224:613–628). Although the loop comprising residues 70–75 is located on the surface of the protein and not near the active site, it appears to be affected indirectly by trisaccharide binding such that the loop shifts toward the active site and becomes relatively immobilized. The source of this loop movement appears to be the anchoring of Trp 62, located in the active site cleft, as it forms a hydrogen bond with O6 of the N‐acetylglucosamine at site C. Good electron density for the trisaccharide in the PEWL complex structure shows that Asp 101 is involved in hydrogen bonding interactions with the terminal sugar residue.
Homology model of human interferon‐α8 and its receptor complex

Published: June 2010

AbstractHuman interferon‐α8 (HuIFNα8), a type I interferon (IFN), is a cytokine belonging to the hematopoietic super‐family that includes human growth hormone (HGH). Recent data identified two human type I IFN receptor components. One component (p40) was purified from human urine by its ability to bind to immobilized type I IFN. A second receptor component (IFNAR), consisting of two cytokine receptor‐like domains (D200 and D200′), was identified by expression cloning. Murine cells transfected with a gene encoding this protein were able to produce an antiviral response to human IFNα8. Both of these receptor proteins have been identified as members of the immunoglobulin superfamily of which HGH receptor is a member. The cytokine receptor‐like structural motifs present in p40 and IFNAR were modeled based on the HGH receptor X‐ray structure. Models of the complexes of HuIFNα8 with the receptor subunits were built by superpositioning the conserved Cα backbone of the HuIFNα8 and receptor subunit models with HGH and its receptor complex. The HuIFNα8 model was constructed from the Cα coordinates of murine interferon‐β crystal structure. Electrostatic potentials and hydrophobic interactions appear to favor the model of HuIFNα8 interacting with p40 at site 1 and the D200′ domain of IFNAR at site 2 because there are regions of complementary electrostatic potential and hydrophobic interactions at both of the proposed binding interfaces. Some of the predicted receptor binding residues within HuIFNα8 correspond to functionally important residues determined previously for human IFNα1, IFNα2, and IFNα4 subtypes by site‐directed mutagenesis studies. The models predict regions of interaction between HuIFNα8 and each of the receptor proteins, and provide insights into interactions between other type I IFNs (IFN‐α subtypes and IFN‐β) and their respective receptor components.
