Leading ethically at the intersection where worlds collide
Authors: Fluker Walter Earl 
Published: September 2009

AbstractWhen leaders ask people to change, they must expect resistance at the intersection. Leaders must discern, deliberate and decide on the fitting response to challenges that arise at the intersection. To discern, deliberate and decide effectively, leaders must re‐examine their core values and assumptions about identity (character); clarify relationships with others in their environment (civility); and maintain strong ties with their primary network of discourse and practice (community).
Aberrant protein expression is associated with decreased developmental potential in porcine cumulus–oocyte complexes
Authors: Paczkowski Melissa , Krisher Rebecca 
Published: September 2009

AbstractOocyte developmental competence is progressively obtained during pubertal development in females. Poor developmental potential in oocytes derived from prepubertal females suggests that essential processes required for oocyte development have not been fulfilled. The objective of this experiment was to analyze the protein profiles of porcine cumulus–oocyte complexes (COC) derived from cyclic and prepubertal females to identify alterations in protein abundance that correlate with developmental potential. COC complexes, aspirated from prepubertal and cyclic ovaries, were pooled into three replicates of 400 COCs each per treatment in ∼100 µl SOF‐HEPES medium. Protein samples were extracted and analyzed by two‐dimensional differential in gel electrophoresis (2D‐DIGE). Over 1,600 proteins were resolved on each of the three replicate gels. Sixteen protein spots were identified by mass spectrometry, representing 14 unique, differentially expressed proteins (volume ratio greater than 1.3). Glutathione‐S‐transferase and pyruvate kinase 3 were more abundant in COCs derived from cyclic females, whereas soluble epoxide hydrolase and transferrin were more abundant in prepubertal derived COCs. Abundance of several glycolytic enzymes (enolase 1, pyruvate kinase 3, and phosphoglycerate kinase) was increased in COCs derived from cyclic females, suggesting glucose metabolism is decreased in prepubertal derived COCs. We conclude that the abundance of proteins involved in metabolism and oxidative stress regulation is significantly altered in prepubertal derived COCs and may play a role in the mechanisms resulting in developmental competence.

Sensory information, instruction in a coping strategy, and recovery from surgery
Authors: Johnson Jean E. , Rice Virginia H. , Fuller Sarah S. , Endress M. Patricia 
Published: September 2009

AbstractA study of 81 cholecystectomy patients evaluated the relative contributions of instruction in a specific coping strategy and two types of informational interventions on subjective and objective indicators of recovery from surgery. The two experimental factors in the 2 × 3 × 2 factorial design were instruction in coping activities (present or absent) and information (description of typical sensations, description of typical events, or no information). The nonexperimental factor was preoperative fear (high or low). Self‐report of moods, severity of pain, and bother of ambulation were the subjective indicators. Analgesics received, amount of ambulation, length of postoperative hospitalization, and time after hospital discharge before patients ventured from their homes were the objective indicators. Instruction in coping activities, description of sensations, and description of events all were found to dampen negative moods postoperatively for patients relatively fearful before surgery. Description of typical sensations significantly reduced the length of postoperative hospitalization and time after hospital discharge before patients ventured from their homes. Another sutdy of 68 herniorrhaphy patients, using the same design, resulted in only minor effects for any of the three interventions. Explanations for the different results between studies are offered.
Patient encounters by primary care nurse students
Authors: Chen Shu‐Pi C. , Barkauskas Violet H. , Ohlson Virginia M. , Chen Edwin H. 
Published: September 2009

AbstractStudent‐patient encounter data were systematically documented. Health problems identified by primary care nurse students were classified and analyzed. Primary health care practicums in three areas of specialization were obstetric‐gynecologic, general adult, and pediatric services. A student‐patient encounter form was constructed to record encounter data. A total of 1,689 encounter forms were completed by 30 nurse students enrolled in primary health care practicums during the years 1972–75. The identified health problems were classified by the International Classification of Diseases Adapted for Use in the United States. The results indicated: (a) the focus of primary health care for obstetric‐gynecologic and pediatric patients was on health maintenance, whereas the focus for general adult patients was on illness care; (b) symptoms and ill‐defined health conditions were frequently encountered by the students, particularly with general adult patients; (c) a cluster of health problems was identified for each of the three areas of specialization. The findings seemed to justify the need to develop a health problem classification system for primary health care.
Sex differences in sick role behavior during hospitalization after open heart surgery
Authors: Brown Julia S. , Buchanan Debra , Hsu Lee‐Nah 
Published: September 2009

AbstractThe proposition examined here is that there are sex differences in the enactment of the sick role. Specifically, in comparing the recovery of 50 male and 50 female patients following open heart surgery, it was hypothesized that male patients would (a) be transferred from the cardiac recovery room earlier, (b) be discharged from the hospital earlier, (c) achieve independence in self‐care and in ambulation earlier, and (d) receive fewer pain medications and tranquilizers. Support was found only for the hypotheses of earlier hospital discharge and earlier self‐care. The patient's physical condition—indicated by type of surgery, time in operating room, time on bypass, and units of blood—was related to time in recovery room and length of postoperative hospitalization. Of the variables examined, age emerged as the most powerful predictor of medication dosage, with older patients receiving significantly fewer analgesics and tranquilizers. The following conclusions were reached: (a) the salience of sex role expectations for sick role behavior varies with the particular measure considered and (b) the overall significance of sex role expectations in determining sick role behavior was slight for this sample of seriously ill patients.
Marked improvement in glycaemic control in a type 2 diabetes patient following a liver transplant for cirrhotic steatohepatitis
Authors: Parker V , Smith M 
Published: September 2009

AbstractWe present the case of a 58‐year‐old woman with poorly controlled, insulin‐treated type 2 diabetes mellitus who underwent a liver transplant for cirrhosis due to non‐alcoholic fatty liver disease complicated by encephalopathy and portal hypertension. Within four months of surgery she exhibited marked improvement in insulin sensitivity, as evidenced by reduced exogenous insulin requirement, with cessation of insulin therapy at 11 months and a consequent dramatic improvement in glycaemic control, eventually achieving an optimal glycosylated haemoglobin concentration on no specific diabetes treatment aside from dietary advice. This was despite a standard regimen of immunosuppressive treatments including prednisolone, tacrolimus and sirolimus which all have the propensity to induce insulin resistance. This case provides an interesting insight into the cause and effect of insulin resistance in the setting of non‐alcoholic fatty liver disease. Copyright ©2009 John Wiley & Sons.

AbstractObjectivesHigh incidence of genetic alterations at the microsatellite (MS) DNA level has been reported in asthmatic adults.Working HypothesisThe aim of this study was to investigate whether microsatellite instability (MSI) and loss of heterozygosity (LOH) were detectable phenomena in children with asthma.MethodologyDNA was extracted from sputum and blood cells of 27 children (10.8 ± 2.5 years) with mild to moderate asthma, and from 8 healthy, never‐smoked young adults. Fourteen polymorphic MS markers, namely D5S207, D5S820, D5S637, D6S344, D6S2223, D6S263, SGC35231, D11S1253, D11S1337, D11S97, USAT24G1, D13S273, D14S258, and D14S292, located on chromosomes (chr) 5q, 6p, 11q, 13q, and 14q were used to assess MSI and LOH.ResultsNone of the healthy subjects exhibited any genetic alteration. Five out of 27 children (18.5%) exhibited MSI or LOH in sputum cells versus blood samples from which 3 in the marker USAT24G1 (chr 13q14.1), 1 in the marker D14S258 (chr 14q23‐q24.3), and 1 in the marker D5S637 (chr 5q12‐q13). Compared to a previous study, with asthmatic adults, whereas MSI and/or LOH was exhibited in ∼60% of the cases, the current study reported <20% of genetic alterations, at the MS DNA, in asthmatic children.ConclusionsOur results showed that genetic instability in the MS DNA, is present in asthmatic children, but to less extent than in adult asthmatics from previous studies. These findings may support the hypothesis that somatic mutations may be early acquired in the natural course of asthma and could represent another contributor to the molecular pathogenesis of the disease. However, further studies are needed to clarify this hypothesis. Pediatr Pulmonol. ©2009 Wiley‐Liss, Inc.
Quantum bit‐error rate in plug‐and‐play quantum key distribution systems caused by axial magnetic fields
Authors: Mecozzi A. , Antonelli C. , Brodsky M. 
Published: September 2009

AbstractWe provide a formalism for the polarization evolution in plug and play quantum key distribution systems, and adapt this formalism for the aggregate Faraday effect in fibers arising from an axial magnetic field. We show the implication of such field on detector readings, and offer a formal expression for quantum bit‐error rate (QBER) for these systems. Assuming a Maxwellian statistics for the Faraday angle, as predicted by recent analytical and numerical studies, we finally calculate the average QBER.
Innovation search of new ventures in a technology cluster: the role of ties with service intermediaries
Authors: Zhang Yan , Li Haiyang 
Published: September 2009

AbstractIn this study, we examine the relationships between new ventures' ties with service intermediaries (i.e., technology service firms, accounting and financial service firms, law firms, and talent search firms) and their product innovation in the context of a technology cluster. Because service intermediaries sit at the intersection of many firms, organizations and industries, they maintain extensive networks in a cluster. We propose that new ventures' ties with service intermediaries enable the ventures to plug into these networks and contribute to the ventures' product innovation by broadening the scope of their external innovation search and reducing their search cost. Moreover, we argue that the positive relationships between new ventures' ties with service intermediaries and their product innovation will become stronger when search in the networks in the cluster is more important to the ventures' product innovation. Based upon a sample of new ventures in a technology cluster in China, our results support these arguments. Copyright © 2009 John Wiley & Sons, Ltd.
The sliding isolation pendulum – an improved recentring bridge bearing
Authors: Braun Christian 
Published: September 2009

AbstractSliding isolation pendulum bearings, known as seismic isolators, with adaptations for the service condition, represent improved recentring bridge bearings. They are an attractive alternative to elastomeric bearings for the support of structures on recentring bearings, which lead to a better distribution of horizontal loads as well as to a reduction in constraints. In combination with a special sliding material and characterized by long life and high loadbearing capacity, sliding isolation pendulum bearings have small dimensions as well as the capability a exact presetting and for horizontal stiffness that is independent of load capacity, change of material characteristics due to temperature, ageing and manufacture. Further, the requirements in terms of serviceability of a bridge bearing are upheld.
A micromechanical model for martensitic phase‐transformations in shape‐memory alloys based on energy‐relaxation
Authors: Bartel T. , Hackl K. 
Published: September 2009

AbstractWe develop a micromechanical model for single‐crystalline materials undergoing diffusionless solid‐to‐solid phase transitions. It is based on the specification of laminated microstructures on the materials' microscale and hence is designed to approximate the rank‐1‐convex hull of the underlying energy‐density for the phase‐mixture. In order to capture the hysteretic behavior of such materials like shape‐memory‐alloys we also account for dissipation by means of evolution equations for the inelastic internal variables. In this context, we derive different evolution‐laws from inelastic potentials via least‐action principles. Several material‐point computations emphasize the characteristics of the presented model.
Numerical study of the effect of Navier slip on the driven cavity flow
Authors: He Q. , Wang X.‐P. 
Published: September 2009

AbstractWe study the driven cavity flow using the Navier slip boundary condition. Our results have shown that the Navier slip boundary condition removes the corner singularity induced by the no‐slip boundary condition. In the low Reynolds number case, the behavior of the tangential stress is examined and the results are compared with the analytic results obtained in [14]. For the high Reynolds number, we study the effect of the slip on the critical Reynolds number for Hopf bifurcation. Our results show that the first Hopf bifurcation critical Reynolds number is increasing with slip length.
Rotation of a slender particle in a shear flow: influence of the rotary inertia and stability analysis
Authors: Altenbach H. , Brigadnov I. , Naumenko K. 
Published: September 2009

AbstractThe rotation of an inertialess ellipsoidal particle in a shear flow of a Newtonian fluid has been firstly analyzed by Jeffery [17]. He found that the particle rotates such that the end of its axis of symmetry describes a closed periodic orbit. In the special case of a slender particle the Jeffery solution predicts the particle alignment parallel to the streamlines. In a recent publication [3] it was shown that the orbits are no longer observable if the rotary inertia is taken into account. Furthermore, in the case of a slender particle the inertia may cause the jump over the equilibrium alignment. In this paper we address a detailed analysis of the slender particle behavior in the shear flow. We recall the constitutive equation for the hydrodynamic moment and formulate equations of rotary motion. For a special initial condition we reduce the problem to a single second‐order ordinary differential equation with respect to the angle of rotation about a fixed axis. The phase portrait of this equation illustrates different cases of the particle behavior depending on the initial conditions and the “inertia” parameter. They include the particle alignment to a semi‐stable equilibrium position, the non‐uniform rotation about a fixed axis as well as the quantization effect (the particle locates in the neighborhood of the first equilibrium point over a relatively long time and then rotates towards the next equilibrium point).
On the constraint problems of sleigh

Published: September 2009

AbstractTo assess the traditional solutions of the constraint problems of sleigh, we introduce a resistent torque acting on the knife blade. The derived solutions conform with experience whereas the traditional counter‐intuitive results follow from our findings as special cases when the resistent torque is very small or/and the length of the knife blade vanishes.

Abstract

Background
Lateral femoral cutaneous nerve (LFCN) injury is a common complication in the Smith-Petersen approach to the hip. This complication may be induced by neural ischemia or direct trauma during the procedure. The purpose of this study was to investigate the relationship between the neural ischemia of LFCN and postoperative sensory disturbance.

Materials and methods
Nineteen patients who underwent periacetabular osteotomy through the Smith-Petersen approach were investigated. To evaluate neural ischemia, we measured the blood flow of LFCN using a laser Doppler flowmetry. The measurements were performed before and after osteotomy at the point 1 cm distal from the lower border of the inguinal ligament. LFCN was retracted to the medial side during the procedure. There was no direct trauma to LFCN in all cases. Postoperative sensory disturbance was evaluated at 2 weeks, 3 months, and 1 year follow-up after surgery.

Results
After osteotomy, the blood flow of LFCN was decreased to 2.4 from 3.3 ml min−1 100 g−1 when compared with that before osteotomy (P < 0.01). Postoperatively, 14 of 19 patients had sensory disturbance at 2 weeks, 8 of 19 patients at 3 months, and 2 of 19 patients at 1 year follow-up. The blood flows of both patients who had persistent symptoms over 1 year after surgery had been decreased by more than 50% during operation.

Conclusions
Decrease of blood flow of LFCN by more than 50% seems to cause persistent symptoms after surgery through the Smith-Petersen approach even if direct trauma to the nerve is avoided. Excessive traction by retractors is thought to be the main cause of blood flow reduction.

SummaryMotor disturbances are very common in paediatric neurology. Often families can be reassured that these are just variants of normal development. However, abnormal movements can also be the hallmark of severe brain dysfunction of different and complex origins. This review concentrates on motor disturbances as frequent and important symptoms of inborn errors of metabolism. A structured diagnostic approach is developed taking into account age‐dependent physiological developments and pathophysiological responses of gross and fine motor functions. A series of investigations are presented with the primary aim of early diagnosis of treatable conditions. The correct recognition and differentiation of movement disorders (ataxia, rigid akinetic syndrome (‘parkinsonism’), dystonia, athetosis, tremor, and others), spasticity, and neuromuscular disorders, requires profound neurological expertise. A high level of suspicion and close interaction between paediatric neurologists and specialists in inborn errors of metabolism are indispensable to effectively and timely identify patients in whom motor disturbances are the presenting and/or main symptom of an inborn error.
Role of the Disease in the Psychological Impact of Pre‐Symptomatic Testing for SCA2 and FAP ATTRV30M: Experience with the Disease, Kinship and Gender of the Transmitting Parent

Published: September 2009

AbstractTo identify possible factors affecting the psychological impact of pre‐symptomatic testing for spinocerebellar ataxia type 2 (SCA2) and familial amyloid polyneuropathy (FAP ATTRV30M), we studied (1) the effect of previous experience with the disease in the family, (2) kinship with the closest affected relative and (3) gender of affected parent, when adapting to test results; as well as (4) differences in the course of psychological wellbeing in 63 subjects (28 at‐risk for FAP ATTRV30M, and 35 at risk for SCA2), who pursued predictive testing for these diseases, in Cuba and in Portugal. Our research shows that individuals with little or no experience with the disease in their family exhibited more anxiety; at‐risk subjects for SCA2 or FAP ATTRV30M who had a first degree relative with the disease showed lower levels of anxiety and depression during pre‐symptomatic testing. Also those with an affected mother had lower levels of depression, either immediately, or one year after receipt of test results. Adaptation to pre‐symptomatic testing results differed for subjects at‐risk for the two different conditions. Unlike the FAP ATTRV30M families, carriers for SCA2 reported pathological levels of depression immediately after‐testing (3 weeks), although those levels had returned to normal levels at 6 months. Subjects at‐risk for FAP ATTRV30M tended to have less anxiety than those tested for SCA2, at the one‐year follow‐up. Overall, depression levels improved over time, while anxiety remained more constant. A longer awareness of the disease in the family, closer kinship, and a transmitting mother all lessened the impact of pre‐symptomatic testing, as expressed by the post‐test levels of anxiety and depression.

Abstract
Quantum dot is a special kind of nanomaterial composed of periodic groups of II–VI, III–V or IV–VI materials. Their high quantum yield, broad absorption with narrow photoluminescence spectra and high resistance to photobleaching, make them become a promising labeling substance in biological analysis. Here, we report a quick and parallel analytical method based on quantum dots for ToRCH-related antibodies including Toxoplasma gondii, Rubella virus, Cytomegalovirus and Herpes simplex virus type 1 (HSV1) and 2 (HSV2). Firstly, we fabricated the microarrays with the five kinds of ToRCH-related antigens and used CdTe quantum dots to label secondary antibody and then analyzed 100 specimens of randomly selected clinical sera from obstetric outpatients. The currently prevalent enzyme-linked immunosorbent assay (ELISA) kits were considered as “golden standard” for comparison. The results show that the quantum dots labeling-based ToRCH microarrays have comparable sensitivity and specificity with ELISA. Besides, the microarrays hold distinct advantages over ELISA test format in detection time, cost, operation and signal stability. Validated by the clinical assay, our quantum dots-based ToRCH microarrays have great potential in the detection of ToRCH-related pathogens.
