On‐line determination of animal cell concentration in two industrial high‐density culture processes by dielectric spectroscopy
Authors: Ducommun P. , Kadouri A. , von Stockar U. , Marison I. W. 
Published: August 2002

AbstractDielectric spectroscopy was applied to two industrial high cell density culture processes and used to determine on‐line the concentration of CHO cells immobilized on macroporous microcarriers in a stirred bioreactor and in a packed‐bed of disk carriers. The cell concentration predicted from the spectroscopic data was in excellent agreement with off‐line cell counting data for both processes. Deviations between the two counting methods only occurred in the case of a significant decrease of the cell viability, from 93% to 64%, which induced a change of the average cell size in the culture. Results for the packed‐bed process were further confirmed by the application of indirect yield models based on the measurement of glucose, lactate, and the protein of interest. Moreover, dielectric spectroscopy was used as a tool to characterize the packed‐bed process. It was possible to determine both the maximum cell concentration that could be reached in the culture system, 2.0 × 1011 cell per kg of disk carrier, and to quantify the increase of specific protein productivity induced by the production phase, from 5.14 × 10−8 μg cell−1 h−1 to 4.24 × 10−7 μg cell−1 h−1. © 2002 John Wiley & Sons, Inc.

Published: August 2002

AbstractA new micelle capillary electrophoresis based on cyclodextrin micellar electrokinetic chromatography (MEKC) for the determination of bisphenol A and 10 alkylphenols in rat serum is reported. Several surfactants and dextrins were studied. Bisphenol A and alkylphenols were separated using a 50 µm × 50 cm capillary with 20 mM borate phosphate buffer (pH 8.0) containing 20 mM sodium dodecylsulfate and 5 mM γ‐cyclodextrin as carrier. The method could determine 0.6–2000 µg/mL of phenols in 100 µL serum by photometric detection at 214 nm. Using 2.0 mL serum, 1.0 ng/mL of phenols could be determined. The relative standards deviations were 6.3–7.7% at 10 µg/mL in serum. The recoveries were 91.8–93.0% with 10 µg/mL serum samples. Copyright © 2001 John Wiley & Sons, Ltd.
Government and NGO partnership in managing community‐based water resources in Vietnam: a case study of Thai Long Dam Project
Authors: Sinh Bach Tan 
Published: August 2002

AbstractEconomic reform policy called ‘Doi Moi’ introduced by the Government of Vietnam at the end of 1980s opened new opportunities of community‐based involvement in the policy and decision‐making at various local levels. Innovations such as decentralization of decision‐making power to lower administrative level, and recognition of the local community's role in managing their natural resources, e.g. transfer of irrigated water management right to local communities, were introduced.Significantly, this new institutional framework also facilitated greater civil society involvement in Vietnam. The Water Users Cooperative (WUC) set up through the Thai Long Dam Project mobilized local farmers to participate and manage their local resources in a sustainable manner. Through this process, the WUC was able to strengthen itself as a civil society institution that mediates between the individual and the state, as well as a forum for increasing government responsiveness and accountability.The success of the WUC of the Thai Long Project implies that the Vietnamese civil society is playing a more active role in the decision‐making process.

Who's in, who's out, and who's back: follow‐up data on 59 juveniles incarcerated in adult prison for murder or attempted murder in the early 1980s
Authors: Heide Kathleen M. , Spencer Erin , Thompson Andrea , Solomon Eldra P. 
Published: August 2002

AbstractSince the mid‐1980s, when juvenile arrests for violent crime increased dramatically, interest has focused on juvenile offenders who commit violent acts. Legislatures across the United States have enacted a variety of measures to “get tough” with juveniles in response to escalating crime rates and the perceptions that longer sentences were needed. This manuscript provides follow‐up data on 59 juveniles who were committed to the adult Department of Corrections in Florida during the period January 1982 through January 1984 for one or more counts of murder, attempted murder, or, in a few cases, manslaughter. Although many of these adolescents received lengthy prison sentences, more than two‐thirds had been released from prison prior to November 1999. This article presents data on amount of time served and recidivism over the 15 to 17 year period. Results indicated that 60 percent of sample subjects released from prison were returned to prison, and most of those who failed did so within the first three years of release. Findings from the present study, when examined in the context of previous comparative follow‐up studies of delinquent youths, suggest that the dialogue on how to handle violent youths must be continued if juvenile homicide offenders are going to be released to society at some point in the future.

Mixed group validation: a method to address the limitations of criterion group validation in research on malingering detection*
Authors: Frederick Richard I. 
Published: August 2002

AbstractMixed group validation (MGV) is offered as an alternative to criterion group validation (CGV) to estimate the true positive and false positive rates of tests and other diagnostic signs. CGV requires perfect confidence about each research participant's status with respect to the presence or absence of pathology. MGV determines diagnostic efficiencies based on group data; knowing an individual's status with respect to pathology is not required. MGV can use relatively weak indicators to validate better diagnostic signs, whereas CGV requires perfect diagnostic signs to avoid error in computing true positive and false positive rates. The process of MGV is explained, and a computer simulation demonstrates the soundness of the procedure. MGV of the Rey 15‐Item Memory Test (Rey, 1958) for 723 pre‐trial criminal defendants resulted in higher estimates of true positive rates and lower estimates of false positive rates as compared with prior research conducted with CGV. The author demonstrates how MGV addresses all the criticisms Rogers (1997b) outlined for differential prevalence designs in malingering detection research. Copyright © 2000 John Wiley & Sons, Ltd.
Upper dental prosthesis instability consecutive to the resection of a cerebral tumor
Authors: Pérusse Rénald , LaFlèche Roland , Tremblay Steve 
Published: August 2002

AbstractA 57‐year‐old female patient was evaluated for an unstable maxillary dental prosthesis. The patient stated that approximately 2 weeks prior to this consultation the prosthesis was relined four times. Despite this, it often had a tendency to shift during meals. On the other hand, she is very satisfied with a complete fixed prosthesis on implants in the mandibular arch. She has been wearing this latter lower prosthesis for the same length of time as the upper prosthesis. She indicated that a similar problem existed with the former upper prosthesis, resulting in her consulting a prosthodontist. Clin. Anat. 14:269–271, 2001. © 2001 Wiley‐Liss, Inc.
Sternomastoid paradox
Authors: Fitzgerald Turlough 
Published: August 2002

AbstractIn the standard routine for testing cranial nerve function following a cerebrovascular accident (CVA) compromising the corticonuclear supply to the cranial nerves, sternomastoid muscle (SCM) function is checked by means of head rotation against resistance. SCM appears to be an exception to the generally contralateral motor weakness resulting from a CVA. The thrust of this article is that appearances can be deceptive: SCM is more likely to be a postural stabilizer than a prime mover in head rotation. Clin.

Developing an intelligent system for teaching pre‐tender cost estimating of office building projects
Authors: Shen Qiping , Fong Patrick S. W. , Deng Michael Z. M. 
Published: August 2002

AbstractPre‐tender cost estimating of office building projects requires extensive knowledge and expertise. Due to the lack of design information in the early design stages, it is extremely difficult for cost engineers or quantity surveyors to arrive at an accurate cost estimate. This paper presents the design and testing of a knowledge‐based system that enables students to learn cost estimating of building projects in the conceptual design stages. The system, embedded with knowledge from experts, has been proved to be a very useful teaching and learning tool. © 2001 John Wiley & Sons, Inc. Comput Appl Eng Educ 9: 26–36, 2001
Mental disease postpartum and parent‐infant interaction—evaluation of videotaped sessions
Authors: Albertsson‐Karlgren Ulla , Graff Magdalena , Nettelbladt Per 
Published: August 2002

AbstractIn order to investigate the influence of maternal mental illness postpartum on mother‐infant and father‐infant interaction, infants of 14 mentally ill women admitted to hospital within 6 months after delivery were compared to infants of 22 women who had been somatically ill. Videotaped sessions when the infant was 10 months old revealed that mothers in the psychiatric sample showed less sensitivity in comparison to mothers in the somatic sample. When the infant was 2 years old, mothers in the psychiatric sample showed less positive affect and less link‐infant follow (stimulation dimension) as compared to the somatic mothers. However, there were no differences between fathers in the psychiatric sample and fathers in the somatic sample in any of the interaction variables. In the psychiatric sample, fathers showed more warmth as compared to mothers. In the somatic sample, fathers scored higher than mothers on autonomy but lower than mothers on link‐infant follow (stimulation dimension). A possible interpretation of our data was that the mental illness of the mothers may lead to a more active parenting role of the father in order to buffer the deficit in the mother‐infant relation.

Peer victimization and self‐esteem of ethnic minority group children
Authors: Verkuyten Maykel , Thijs Jochem 
Published: August 2002

AbstractAn experimental study was carried out among Turkish children (10 to 12 years) living in the Netherlands for examining the relationship between peer victimization and self‐esteem. Related to the social psychological distinction between personal and social identity, a distinction was made between personal and ethnic self‐esteem and between personal and ethnic victimization. It was found that personal self‐esteem negatively predicted personal victimization but not ethnic victimization, and ethnic self‐esteem tended to predict ethnic victimization but not personal victimization. Furthermore, peer victimization had a negative causal effect on momentary self‐feelings independent of the level of self‐esteem. In addition, peer victimization based on ethnic group membership had a somewhat stronger negative effect on self‐feelings than victimization based on personal characteristics.

Incomplete retention after direct myocardial injection
Authors: Grossman P. Michael , Han Zhenguo , Palasis Maria , Barry James J. , Lederman Robert J. 
Published: August 2002

AbstractDirect intramyocardial injection may permit local delivery of protein and gene therapy agents for myocardial and coronary artery disease. Little is known about the immediate fate of materials administered via percutaneous endomyocardial catheters or via surgical epicardial injection. In this study, we use a novel method to evaluate the acute retention of agents injected directly into the myocardium, compare epicardial with the percutaneous endocardial and postmortem delivery, and evaluate the influence of injectate volume on myocardial retention. Fifteen 40–50 kg pigs underwent overlapping myocardial injections using a percutaneous endomyocardial catheter, an epicardial needle via an open chest, and epicardial needle postmortem. Multiple distinct 15 μ neutron‐activated microsphere species were used as tracers. Two or three myocardial walls were injected in each animal using 3.5 mm, 27–28 gauge needles at varying injectate volumes. Animals were sacrificed immediately. Myocardial walls were divided and multiple microsphere species were quantified. In an additional study, nine 70 kg pigs underwent percutaneous endomyocardial injections with replication‐deficient adenovirus encoding for the production of lac‐Z. The injectate volume was varied, while the viral particle number remained constant. The animals were sacrificed 5 days after the percutaneous injections; the heart, liver, and spleen were collected for β‐galactosidase activity. Endomyocardial injection was associated with 43% ± 15% microsphere retention, compared with 15% ± 21% (P < 0.01) retention of open chest epicardial injection and 89% ± 60% (P < 0.01) for postmortem injection. Reducing the injectate volume from 100 to 10 μL improved microsphere retention (P = 0.01). There was a trend toward improved viral transfection associated with smaller injection volumes. Despite direct intramyocardial administration, a significant fraction of injectate is not retained locally. Catheter‐based needle endomyocardial injection is associated with equivalent or superior injectate retention compared with open chest epicardial injection. Proportionately, more injectate may be retained at lower volumes. Loss may involve a combination of channel leakage, venous, and lymphatic return.

Assessment of NOGA catheter stability during the entire cardiac cycle by means of a special needle‐tipped catheter

Published: August 2002

AbstractThe NOGA system maps regional myocardial function and delivers local catheter‐based therapeutics, requiring stability and precise localization of the catheter tip throughout the cardiac cycle. A special catheter having a retractable needle at its tip was used to compare tip stability with and without needle insertion into the myocardium, assuming this prevents catheter slippage. For multiple sites in seven pig left ventricles, we recorded sets of three consecutive point locations: pre‐, post‐, and during needle insertion. In‐point location stability (LocStab), defined as the mean displacement between catheter tip trajectories of two consecutive cardiac cycles at a specific point, did not differ among the three groups of points (mean, 1.33 ± 0.61 mm; P = 0.37 by ANOVA), indicating that trajectories are equally stable and repeatable with or without needle insertion. Between‐point LocStab(p1,p2), i.e., displacement between the trajectories of two different points (p1 and p2) at the same location, was not increased when p1 = a needle insertion point and p2 = a noninsertion point, compared to both p1,p2 = noninsertion points, suggesting that slippage of noninsertion points is negligible. In conclusion, catheter tip trajectories at any location are highly stable throughout the cardiac cycle. Cathet Cardiovasc Intervent 2001;52:400–406. © 2001 Wiley‐Liss, Inc.
Use of a percutaneous arterial suture device (Perclose) in patients undergoing percutaneous balloon aortic valvuloplasty
Authors: Michaels Andrew D. , Ports Thomas A. 
Published: August 2002

AbstractPercutaneous balloon aortic valvuloplasty has been used as a therapeutic option for patients with severe aortic stenosis who are not candidates for aortic valve replacement. This procedure has been limited by both the high rate of aortic valve restenosis and high procedural morbidity related chiefly to the large femoral arteriotomies required. The purpose of this study was to assess the feasibility and vascular complication rate using the “Preclose” technique in patients undergoing balloon aortic valvuloplasty. We evaluated the immediate and 30‐day results in 18 consecutive patients undergoing this procedure. Angiographically significant peripheral vascular disease was present in 39% of cases. Aortic balloon dilation produced significant decreases in the mean aortic valve pressure gradient from 55 ± 20 mmHg to 30 ± 22 mmHg (P < 0.001). Closure of the arteriotomy with an 8F (10F in 1 case) Perclose device led to immediate hemostasis in all patients. Perclose of the contralateral femoral arterial site with a 6F device was attempted in 50%, all of which were successful. The mean length of bed rest was 4.5 ± 0.9 hr. No procedural was observed. No patient had a local vascular complication, and no patient required blood product transfusion after the procedure. The use of the “Preclose” technique for closure of femoral arteriotomies after balloon aortic valvuloplasty is feasible and associated with a low rate of periprocedural and short‐term vascular complications.

AbstractMyointimal hyperplasia after percutaneous transluminal coronary angioplasty (PTCA) is a key component of the process of restenosis. The c‐myc is a critical cell‐cycle division protein involved in the formation of neointima. We evaluated the long‐term impact of local delivery of c‐myc neutrally charged antisense oligonucleotides (Resten‐NG) on myointimal hyperplasia after PTCA in a rabbit model. PTCA was performed in the iliac arteries of 25 New Zealand white rabbits, using a Transport\T catheter at 8 atm for 30 sec, three times; 500 μg Resten‐NG (n = 11) or saline (n = 14) was delivered to the PTCA site at 2 atm with the outer balloon for 2 min. The diet was supplemented with 0.25% cholesterol for 10 days before and 60 days after PTCA. Angiography was performed at harvest, and vessels were fixed in formalin, processed, and stained with hematoxylin and eosin (H&E) and Movat. Quantitative angiography showed that local delivery of antisense c‐myc at PTCA reduced late luminal loss from 1.8 ± 0.30 mm in control animals to 0.90 ± 0.30 mm in the treatment group (P = 0.001). Histological analysis by planimetry showed that intimal areas were 1.67 ± 0.44 mm2 and 0.82 ± 0.32 mm2 in the control and antisense delivery groups, respectively (P < 0.05). We conclude that local delivery of Resten‐NG inhibited myointimal hyperplasia after PTCA in cholesterol‐fed rabbits for up to 60 days.

AbstractA new quantitative parameter, diffuse index (DI), was proposed to evaluate objectively whether in‐stent restenosis is diffuse or focal in nature. A total of 343 patients (346 lesions) with Wiktor‐GX, AVE MS‐II, or JOMED stents were evaluated at follow‐up angiography. According to the QCA‐CMS definition, lesion length is derived from the 100% reference diameter function (RDF). By moving the RDF downward, the lesion length, LL(x), at each percentage x of the RDF can be calculated. We have defined the DI by the ratio of this calculated length LL(x) and the total stent length, SL, in other words, DI = [LL(x)/SL]. The percentage plaque area (% PA) was calculated by dividing the plaque area by the sum of the plaque area and luminal area within the stent. An excellent correlation was found between the DI at 88% RDF and the % PA in all three stents (r > 0.88). The individual correlation curves were nearly identical, independent of the type of stent. Furthermore, based on the overall data, the combination of a DI > 0.8 and % PA > 30% correlated with a high incidence of subsequent major adverse cardiac events (13/25 = 52%). From these data, it can be concluded that the diffuse index is a new objective quantitative parameter to describe whether in‐stent restenosis is of focal or diffuse nature.
