From soap opera to science: Towards gaining access to the psychopaths who live amongst us
Authors: Kirkman Christine A. 
Published: October 2005

This idiographic and essentially exploratory study examined the unique experiences of 20 women who had been victimized within the context of heterosexual relationships with a male partner who was rated as having the characteristics associated with psychopathy.An integrated approach, using questionnaires, and biographical and narrative data, was utilized. The experimental group consisted of 20 women who had partnered males rated by the women on the Hare P‐SCAN (Hare & Herve, 1999) as having many or most of the features of psychopathy. As this was the first reported use of the Hare P‐SCAN to provide partner ratings, norms for scorings on this assessment tool were obtained from ratings provided by a control group of a random sample of 100 women who had completed the Hare P‐SCAN and provided ratings for their last male partner. Four two‐tailed independent samples t tests were conducted to test for significant differences in scorings between the two groups. Following screening, semi‐structured interviews were conducted with the experimental group, that is, 20 women who had partnered males with psychopathic traits.The four independent samples t test showed that significant differences occurred between the ratings of male partners by women in the experimental group and ratings provided by the control group. Narrative data, generated from written accounts and interviews with women in the experimental group, was successful in clarifying the manner in which males with the personality traits which define psychopathy managed the heterosexual relationship and the nature and patterns of the abusive behaviours which occurred in this context.

Objectives. The stability of attachment‐related anxiety and avoidance and their relationship with influential personality models are issues worth further investigation. Studying discriminant validity with respect to aspects of personality deemed as prevalently heritable, such as temperament, is particularly important. Our aims were to examine the stability of attachment dimensions and to study their relationship with psychological distress, the Big Five factors, and temperament and character dimensions.Methods. The Experiences in Close Relationships (ECR) questionnaire, the State‐Trait Anxiety Inventory (STAI), the Zung depression scale (ZDS), the Temperament and Character Inventory (TCI‐125), and the Big Five Questionnaire (BFQ) were administered to 222 undergraduate and graduate students. After 1 month, 115 participants completed again the ECR, the STAI, and the ZDS.Results. Attachment‐related anxiety was modestly correlated with depression and anxiety, while attachment‐related avoidance was modestly correlated with depression. The test–retest reliability of ECR scores was high. Changes in attachment‐related anxiety were not related to changes in depression or anxiety, and changes in attachment‐related avoidance were modestly correlated with changes in depression. In separate multiple regression models also including gender and age, attachment‐related anxiety was correlated with harm avoidance, reward dependence, low novelty seeking, low self‐directedness and low cooperativeness; low energy/extraversion and low emotional stability; attachment‐related avoidance was correlated with low reward dependence and tended to be correlated with low self‐directedness.Conclusions. These findings corroborate the reliability and the convergent and discriminant validity of the ECR, and support the notion that the attachment dimensions are only modestly related to psychological distress and are not redundant with constructs developed within influential personality models such as the five‐factor model and the psychobiological model.

Published: October 2005

The cerebellum plays an essential role in pursuit tracking with the eye and with the hand. During smooth pursuit eye movements, both tracking position and velocity are signaled by Purkinje cells. Purkinje cell simple spike discharge is also modulated by direction and speed during linear manual tracking. This study evaluated how all three parameters, position, movement direction, and speed, are signaled in the simple spike discharge of Purkinje cells during circular manual tracking.Three rhesus monkeys intercepted and then tracked a target moving in a circle in both counterclockwise and clockwise directions across a range of constant target speeds. Two sets of analyses of the simple spike firing of 97 Purkinje cells examined the effects of position, movement direction, and speed. The first approach was the incremental improvement of regression models, initially modeling a pure position dependence, then incorporating movement direction, and finally incorporating speed dependence. The second was a model-independent approach, without any explicit assumptions about the character of the directional tuning or speed effects. Both analyses revealed the same three results: (1) Purkinje cell discharge is spatially tuned, to both the position and direction of movement, and (2) this spatial tuning is not altered by the speed, except (3) the speed scales the average firing and/or depth of modulation.The results suggest that the population of Purkinje cells forms a representation of the entire position-direction space of arm movements, and that the speed modulates the scale of that representation. This speed scaling provides insights into the cerebellar processing of movement-related timing.

Published: October 2005

AbstractThe behavior of a chromatographic column where a single solute is fed in the presence of a suitable modifier is analyzed in the context of equilibrium theory. In particular, the pulse propagation of the solute, whose retention depends on the modifier concentration, has been analyzed as a full‐fledged binary problem by the method of hodograph transformation applied to the pair of quasilinear differential equations. It has been shown that all possible operating conditions can be summarized with respect to the modifier concentration into three cases. These have been solved analytically by constructing the solution first in the hodograph plane, and then mapping it onto the physical plane using the method of characteristics. The peculiar properties of the derived hodograph plane were explained, and their impact on the pulse propagation for the three different cases has been elucidated. For the cases of intermediate adsorptivity of the modifier, the occurrence of solute peaks with infinitely high concentrations; that is, solute impulse, has been proven as well as the phenomena of double solute peaks. © 2005 American Institute of Chemical Engineers AIChE J, 2006
Step and pulse response methods for identification of wiener processes
Authors: Park Ho Cheol , Lee Jietae 
Published: October 2005

AbstractLack of simple identification methods for nonlinear processes hinders field applications of nonlinear control systems. For identification methods that are as simple as those for the first order plus time delay models of linear dynamical processes, graphical and least squares methods to identify Wiener‐type nonlinear processes from standard responses, such as step, pulse, and square‐wave responses, are proposed. Static nonlinear functions are identified independently in Wiener‐type nonlinear processes. Graphical methods extract discrete points of the nonlinear static function or a continuous non‐parametric model of the nonlinear static function iteratively. The least squares method provides a parametric model of the nonlinear static function. The identified static nonlinear function can be used to design a simple linearizing control system. To illustrate the proposed identification methods, simulation and experimental results are given. © 2005 American Institute of Chemical Engineers AIChE J, 2006

Published: October 2005

AbstractOne key point for improving osseous integration of implants is to render them osteopromotive by specifically favoring the adhesion of osteoblasts. Mimicking the physiological adhesion process of osteoblasts to the extracellular matrix improves cell adhesion in vitro and results in improved and earlier osseous integration of implants in vivo. Our approach involves coating titanium implants with a tailor‐made cyclic‐RGD peptide, thus allowing them to bind to specific integrin receptors on the cell surface through multimeric phosphonates. The advantages of this very stable, new type of anchoring for practical application are presented.

Cancer in an incarcerated population
Authors: Mathew Paul , Elting Linda , Cooksley Catherine , Owen Steven , Lin James 
Published: October 2005

AbstractBACKGROUNDThe challenge posed to prison health systems in the U.S. by an immense incarcerated population is significant. However, the patterns of presentation and associated mortality of cancer among the incarcerated population is unknown.METHODSAn historical cohort of cancers diagnosed among inmates of the Texas Department of Criminal Justice over the course of 20 years who were followed at the University of Texas Medical Branch in Galveston, Texas was identified. There were 1807 inmates who were diagnosed with cancer. Two cohorts were chosen for comparison: a random sample of 179,757 patients from the Surveillance, Epidemiology, and End Results (SEER) registry, and an age‐matched, gender‐matched, race‐matched SEER population comprised of 6124 patients (MSEER). Disease sites and associated mortality of the inmate cancer patients were determined and compared with SEER cohorts.RESULTSA marked rise in cancer diagnoses among inmates paralleled the rise in the inmate population. The leading cancers were lung carcinoma, non‐Hodgkin lymphoma (NHL), and carcinomas of the oral cavity and pharynx. Among women, cervical carcinoma was the most common. Lung carcinoma, NHL, and hepatic carcinoma accounted for more cancer deaths among inmates than in the SEER cohort (P < 0.0001 for all comparisons). Lung carcinoma, hepatic carcinoma, and NHL were significantly more common in the inmate cohort than in the MSEER cohort (P < 0.001 for all comparisons). The median survival was inferior in the inmate cohort (21 mos) compared with the SEER cohort (55 mos) and the MSEER cohort (54 mos) (P < 0.0001 for both comparisons).CONCLUSIONSCancers with unique epidemiology and high associated mortality have emerged among the incarcerated. This has significant implications for prison health systems. Cancer 2005. © 2005 American Cancer Society.

Published: October 2005

AbstractUnusual diglycosides composed of D‐hexofuranosyl entities were prepared by a chemoenzymatic route using the α‐L‐arabinofuranosidase, AbfD3. The required, unprotected monosaccharidic donors were first prepared according to multi‐step syntheses. Since one goal of this study was the investigation of donor –1 subsite in the active site of the enzyme, we focused on D‐fucofuranosyl and 6‐deoxy‐6‐fluoro‐D‐galactofuranosyl derivatives which present stereochemical similarities with L‐arabinose series, but also structural variations on the side arm. These substrates were then used in AbfD3‐catalysed hydrolyses to determine the parameters Km and kcat and in AbfD3‐catalysed transglycosylation to evaluate their ability to serve as donor/acceptor. Four disaccharides were thus isolated and characterised, two resulting from β‐(1,2) connection along with two β‐(1,3)‐regioisomers. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
The effect of Nb addition on mechanical properties, corrosion behavior, and metal‐ion release of ZrAlCuNi bulk metallic glasses in artificial body fluid
Authors: Qiu C. L. , Liu L. , Sun M. , Zhang S. M. 
Published: October 2005

AbstractBulk metallic glasses (BMGs) of Zr65 − xNbx‐ Cu17.5Ni10Al7.5 with Nb = 0, 2, and 5 at % were prepared by copper mold casting. Compression tests reveal that the two BMGs containing Nb exhibited superior strength and plasticity to the base alloy. The corrosion behavior of the alloys obtained was investigated in artificial body fluid by electrochemical measurements. It was found that the addition of Nb significantly enhanced the corrosion resistance of the Zr‐based BMG, as indicated by a remarkable increase in corrosion potential and pitting potential. XPS analysis revealed that the passive film formed after anodic polarization was enriched in aluminum oxide and depleted in phosphate ions for the BMGs containing Nb, which accounts for the improvement of corrosion resistance. On the other hand, metal‐ion release of different BMGs were determined in PPb (ng/mL) level with inductively coupled plasma mass spectrometry (ICP‐MS) after being immersed in artificial body fluid at 37°C for 20 days. It was found that the addition of Nb considerably reduced the ion release of all kinds of metals of the base system. This is probably attributed to the promoting effect of Nb on a rapid formation of highly protective film. © 2005 Wiley Periodicals, Inc. J Biomed Mater Res, 2005
Textural characterization of finished and polished composites over time of intraoral exposure
Authors: Turssi Cecilia Pedroso , Rodrigues Antonio Luiz , Serra Mônica Campos 
Published: October 2005

AbstractThis in situ study sought to evaluate the surface roughness evolution of resin composites finished and polished by different methods. A total of 108 rectangular‐shaped specimens of a microfilled and a hybrid composite were cured against a Mylar matrix strip and left unpolished or instrumented with diamond burs, Al2O3‐coated disks, Al2O3‐impregnated UDMA disk, or with diamond burs followed by either one of the disks. After specimens had been profiled for the average surface roughness (Ra, μm), 18 volunteers wore a removable palatal appliance, which accommodated one specimen of each one of the 12 groups investigated. Surface roughness for up to 28 days of intraoral exposure was then measured at 1‐ or 7‐day intervals. A split‐plot ANOVA (α = 0.05) revealed a significant interaction between group and time. Tukey's test and regression analyses ascertained that initially finishing with burs only provided the roughest surface to both composites. Unpolished surfaces and those specimens polished with Al2O3‐coated disks, regardless of previous use of diamond burs, attained smoother surface. The Al2O3‐impregnated UDMA disk was capable of smoothening the surface of the hybrid material previously finished with diamond burs. The roughness achieved after finishing and polishing composites may be either smoothened or roughened after intraoral exposure. On the basis of the roughness range, it is advisable to use Al2O3‐coated disks, regardless of whether diamond burs were previously used. Al2O3‐impregnated UDMA disks (with or without previous application of diamond burs) may be also suitable for instrumenting hybrid restoratives. © 2005 Wiley Periodicals, Inc.

Study on the drug release property of cholesteryl end‐functionalized poly(ε‐caprolactone) microspheres
Authors: Yu Lan , Zhang Hua , Cheng Si‐Xue , Zhuo Ren‐Xi , Li Hua 
Published: October 2005

AbstractEnd‐functionalized poly/oligo(ε‐caprolactone)s were synthesized through the ring‐opening polymerization of ε‐caprolactone initiated by cholesterol with a hydroxyl group. Using the end‐functionalized poly/oligo(ε‐caprolactone)s with different molecular weights, the microsphere drug delivery systems were fabricated using a convenient melting‐emulsion method. The drug release properties of microspheres were investigated with the presence of an enzyme, Pseudomonas cepacia lipase, as well as in the absence of the enzyme. The release profiles can be fitted nicely by the classical empirical exponential expression. Under the hydrolytic condition, the drug release is mainly controlled by Fickian diffusion, and the high molecular weight of the matrix results in a slower drug release rate. Under the enzymatic condition, the drug release is dominated by combined degradation and diffusion mechanism, and the high molecular weight sample exhibits a faster release rate that is mainly caused by the higher degradation rate of the sample with lower cholesteryl moiety content. © 2005 Wiley Periodicals, Inc.

Published: October 2005

AbstractWe describe a novel human gene, named SEL‐OB/SVEP1, expressed by skeletal tissues in vivo and by cultured osteogenic cells. The mRNA expression was analyzed on frozen tissues retrieved by laser‐capture microscope dissection (LCM) and was detected in osteogenic tissues (periosteum and bone) but not in cartilage or skeletal muscle. The SEL‐OB/SVEP1 cDNA of 11,139 bp was in silico translated into a 3574AA protein with expected molecular weight of 370 kDa. The protein is composed of multiple domains including complement control protein (CCP) modules with selectin superfamily signature; sushi and other domains, such as vWA, EGF, PTX, and HYR. Stromal osteogenic cells were analyzed for the protein expression using anti‐SEL‐OB/SVEP1 for immuno‐precipitation and Western blot application confirm the presence of high molecular weight protein. Immuno‐histochemistry and fluorescence‐activated cell sorting (FACS) were applied to detect SEL‐OB/SVEP1 on the surface of stromal cells. ELISA quantified the dependence of protein expression on cell density. Bioinformatic analysis of SEL‐OB/SVEP1 revealed domains compositions recognized in cell surface molecules and suggested its role in cell adhesion. Analysis of mesechymal osteogenic cells' adhesion in presence of anti‐SEL‐OB/SVEP1 antibody demonstrated its interference with initial adhesion stages. In summary, present study describes novel SEL‐OB/SVEP1 protein with a unique composition of functional domains, restricted pattern of expression in skeletal cells and demonstrated involvement in attachment of mesenchymal cells. The unusual composition of functional domains puts SEL‐OB/SVEP1 in the discrete new group of membrane proteins involved in cell adhesion processes. All together makes SEL‐OB/SVEP1 an attractive marker for studying the role of stromal osteogenic cells and their interactions within the bone marrow microenvironment creating a network that regulates the skeletal homeostasis.

Mitochondrial production of oxidants is necessary for physiological calcium oscillations
Authors: Camello‐Almaraz M. Cristina , Pozo Maria J. , Murphy Michael P. , Camello Pedro J. 
Published: October 2005

AbstractMitochondrial involvement in Ca2+ signaling is thought to be due to the effect of mitochondrial Ca2+ removal from and Ca2+ release to cytosolic domains close to ryanodine and IP3 Ca2+ channels. However, mitochondria are a source of low levels of endogenous reactive oxygen species, and Ca2+ release channels are known to be redox‐sensitive. In the present work, we studied the role of mitochondrial production of oxygen species in Ca2+ oscillations during physiological stimulation. Mitochondria‐targeted antioxidants and mitochondrial inhibitors quickly inhibited calcium oscillations in pancreatic acinar cells stimulated by postprandial levels of the gut hormone cholecystokinin. Confocal microscopy using different redox‐sensitive dyes showed that cholecystokinin‐induced oscillations are associated with mitochondrial production of reactive oxygen species. This production is inhibited by application of mitochondria‐targeted antioxidants and mitochondrial inhibitors. In addition, we found no correlation between inhibition of oscillations and mitochondrial depolarization. We conclude that low level production of reactive oxygen species by mitochondria is a necessary element in the development of Ca2+ oscillations during physiological stimulation. This study unveils a new and unexplored aspect of the participation of mitochondria in calcium signals. J. Cell. Physiol. 206: 487–494, 2006. © 2005 Wiley‐Liss, Inc.
