Direct measurement of strain distribution along a wood bond line. Part 1: Shear strain concentration in a lap joint specimen by means of electronic speckle pattern interferometry
Authors: Müller Ulrich , Sretenovic Aleksandra , Vincenti Angela , Gindl Wolfgang 
Published: April 2005

Abstract
Phenol-resorcinol-formaldehyde (PRF) and one-component polyurethane (PUR) resins were used to manufacture single lap joint samples corresponding to EN 302-1. 3D electronic speckle pattern interferometry (ESPI), which enables measurement of spatial displacement of less than 0.1 μm, was used during tensile shear experiments to observe full-field in-plane and out-of-plane deformation of the lap joint samples and to detect strain concentrations in the vicinity of glue lines. Finite element analysis was performed to validate ESPI measurements. In general, ESPI measurements showed that in a lap joint experiment a very small volume of material close to the ends of the overlapping area is highly strained. ESPI and finite element analysis pointed out that PUR glue lines are characterised by much higher shear deformations than PRF glue lines, especially at the ends of the overlapping area. However, due to the lower Young's modulus of PUR resin compared to PRF, higher shear strains but lower shear stress concentrations can be expected in PUR, which was confirmed by the FE model.

Abstract
MALDI-TOF MS differentiated mycelia within pairs each of the closely related indoor wood decay fungi Serpula lacrymans, S. himantioides, Coniophoraputena, C. marmorata, and Antrodia vaillantii, A. sinuosa. The method is thus suitable to identify unknown samples by spectrum comparison.
The soul danced into the body: Nation and improvisation in Istanbul
Authors: Bryant Rebecca 
Published: April 2005

ABSTRACTIn this article, I examine the politics and practices of apprenticeship in the “traditions” of Turkish folk music through playing the bag˘lama, or saz. The saz has become iconically representative of a folk music collected and preserved in the era of nationalism, and I examine the meaning of such a self‐conscious and reflexive tradition's claims to traditionality. I outline the ways in which that tradition is acquired as an aesthetics of self, requiring one to consciously shape the self to become the type of person who can play the saz and, hence, improvise within the sensibility of a tradition.
Boys or men? Duped or “made”? Palestinian soldiers in the Israeli military
Authors: Kanaaneh Rhoda 
Published: April 2005

ABSTRACTSeveral thousand Palestinian citizens of Israel currently volunteer to serve in various branches of the Israeli “security” apparatus. Members of this small group of mostly men are commonly perceived by other Palestinians as traitors to their people and are socially marginalized. Even soldiers who strain and sometimes break the limits of social acceptance, however, relate to their communities in dominant gendered terms. The critiques, explanations, and, occasionally, defenses of soldiering represent much larger concerns about the relationship of Palestinian citizens to the Israeli state, particularly concerns about Israelization, but are measured in relation to a family‐centered provider masculinity. What the state offers or withholds from Arab soldiers plays a powerful role in shaping Palestinian discourses on masculinity and citizenship.

Published: April 2005

Background: This study evaluated the inhibitory activity of triphala on PMN‐type matrix metalloproteinase (MMP‐9) expressed in adult periodontitis patients and compared its activity with another ayurvedic drug, kamillosan, and doxycycline, which has known inhibitory activity.Methods: Matrix metalloproteinases (MMPs) were extracted from gingival tissue samples from 10 patients (six males, four females) with chronic periodontitis. Tissue extracts were treated with the drug solutions, the inhibition was analyzed by gelatin zymography, and the percentage of inhibition was determined by a gel documentation system.Results: The activity of MMPs was significantly decreased with the use of the drugs. Triphala showed a 76.6% reduction of MMP‐9 activity, whereas kamillosan showed a 46.36% reduction at a concentration of 1,500 µg/ml (crude extract) and doxycycline showed a 58.7% reduction at a concentration of 300 µg/ml (pure drug).Conclusion: The present study showed the strong inhibitory activity of triphala on PMN‐type MMPs involved in the extracellular matrix (ECM) degradation during periodontitis.

Published: April 2005

Background: Over the last few decades, oral diseases including periodontitis, have been discussed as a possible risk factor for cardiovascular disease. The purpose of this study was to compare the oral health of age‐matched women with or without coronary heart disease (CHD).Methods: A total of 143 consecutive women, aged 43 to 79 years, with diagnosed CHD underwent a thorough dental examination including a panoramic radiograph and were compared to 50 women, aged 45 to 77 years without CHD.Results: The number of remaining teeth and pathological periodontal pockets (≥4 mm) between the groups differed. The women with CHD had 18.9 ± 8.5 remaining teeth versus 23.4 ± 6.3 teeth in the control group (P <0.001). The CHD group had more pathological periodontal pockets compared to the controls, 14.2 ± 12.4 versus 9.6 ± 13.3 (P = 0.002), respectively. The mean marginal bone level assessed on radiographs was the same in both groups, while the number of vertical bone defects differed (P = 0.022). Dentures were more frequent in the CHD group than in the controls (27% versus 6%, P = 0.022), as was edentulousness, 10.5% versus 0% (P = 0.017), respectively. Multiple regression analysis adjusted for age, smoking, body mass index (BMI), diabetes, education, and place of birth showed a relation between the number of periodontal pockets and CHD with an odds ratio (OR) of 3.8 (1.68 to 8.74), and a tendency between dentures and CHD, with an OR of 4.6 (0.99 to 21.28).Conclusion: This study indicates that women with CHD have worse oral health than those in a comparable group with no history of CHD.

Published: April 2005

Background: The aim of this study was to identify risk indicators for periodontitis using cross‐sectional data from a group of older Thai adults.Methods: The study group consisted of 2,005 individuals, aged 50 to 73 years old. They received detailed medical examinations and periodontal examinations including plaque score, probing depth, and clinical attachment level. These individuals were categorized into mild, moderate, or severe periodontitis if mean clinical attachment level was <2.5 mm, 2.5 to 3.9 mm, or ≥4.0 mm, respectively. The degree of association between the severity of periodontitis and various independent variables was investigated using multinomial logistic regression analysis.Results: The percentage of subjects classified as mild, moderate, and severe periodontitis was 30.5, 53.6, and 15.9, respectively. The prevalence of severe periodontitis was higher in males and increased with age. In univariate analysis, older subjects, males, less educated persons, persons with lower income, persons with higher plaque score, smokers, drinkers, and diabetics were more likely to have both moderate and severe periodontitis. In multivariate analysis, males, less educated persons, persons with higher plaque score, and current smokers were more likely to have moderate periodontitis. Three additional factors including older age, former smokers, and diabetes significantly increased the odds for having severe periodontitis. Income, alcohol consumption, body mass index, and waist circumference had no significant effects on periodontal disease severity in the multivariate model.Conclusions: Our data suggest that age, gender, education, oral hygiene status, smoking, and diabetes are significantly associated with periodontal disease severity in this study group. Longitudinal studies will establish whether these variables are true risk factors. J Periodontol 2005;76:558‐565.

Published: April 2005

Background: Aortic aneurysms affect an increasing number of elderly patients and cause considerable morbidity and mortality. The understanding of the mechanisms involved in the pathogenesis of aortic aneurysms is unclear and little is known about the role of microorganisms in the development of the condition. The aim of the present study was to examine aortic aneurysm samples for the presence of four putative periodontal pathogens: Actinobacillus actinomycetemcomitans, Treponema denticola, Tannerella forsythensis, and Porphyromonas gingivalis.Methods: Fifty‐six samples from the aneurysm wall were obtained from patients undergoing aneurysm repair. DNA was extracted from tissue by conventional methods. Universal eubacterial primers for general detection of bacteria and speciesspecific primers for detection of the periodontal pathogens were used to amplify part of the 16S rRNA gene by polymerase chain reaction (PCR).Results: Bacterial DNA was detected in 50 of the 56 aneurysm samples (89.2%). A. actinomycetemcomitans was found in four samples (7.1%). None of the samples was positive for T. denticola, T. forsythensis, or P. gingivalis.Conclusion: Bacteria are commonly present in aortic aneurysms and may play a role in the development of the condition. Periodontal pathogens are also present. J Periodontol 2005;76:590‐594.

Published: April 2005

Background: Conventional dentoalveolar osseous reconstruction often involves the use of grafting materials with or without barrier membranes. The purpose of this study was to evaluate the efficacy of bone induction for the placement of dental implants by two concentrations of recombinant human bone morphogenetic protein‐2 (rhBMP‐2) delivered on a bioabsorbable collagen sponge (ACS) compared to placebo (ACS alone) and no treatment in a human buccal wall defect model following tooth extraction.Methods: Eighty patients requiring local alveolar ridge augmentation for buccal wall defects (≥50% buccal bone loss of the extraction socket) of the maxillary teeth (bicuspids forward) immediately following tooth extraction were enrolled. Two sequential cohorts of 40 patients each were randomized in a double‐masked manner to receive 0.75 mg/ml or 1.50 mg/ml rhBMP‐2/ACS, placebo (ACS alone), or no treatment in a 2:1:1 ratio. Efficacy was assessed by evaluating the amount of bone induction, the adequacy of the alveolar bone volume to support an endosseous dental implant, and the need for a secondary augmentation.Results: Assessment of the alveolar bone indicated that patients treated with 1.50 mg/ml rhBMP‐2/ACS had significantly greater bone augmentation compared to controls (P ≤0.05). The adequacy of bone for the placement of a dental implant was approximately twice as great in the rhBMP‐2/ACS groups compared to no treatment or placebo. In addition, bone density and histology revealed no differences between newly induced and native bone.Conclusion: The data from this randomized, masked, placebocontrolled multicenter clinical study demonstrated that the novel combination of rhBMP‐2 and a commonly utilized collagen sponge had a striking effect on de novo osseous formation for the placement of dental implants.

Published: April 2005

Background: Normal wound healing processes have been shown to be altered in diabetes, and the effect of the diabetes on bone‐to‐implant contact (BIC) once osseointegration has been established is still unknown. The purpose of this study was to histologically evaluate the bone‐to‐implant contact in uncontrolled and insulin‐controlled rats in which diabetes was induced following the establishment of osseointegration.Methods: Thirty‐two rats were assigned to eight different treatment groups of four each. Titanium plasma‐sprayed (TPS) implants were placed in the femora of each animal, and allowed to osseointegrate for 28 days before diabetic induction. Daily insulin injections were given to four groups of rats and the other four groups received no insulin (uncontrolled). The rats were sacrificed at 1, 2, 3, and 4 months following diabetic induction.Results: The results indicated that at 1, 2, 3, and 4 months, there was more BIC in the insulin‐controlled groups compared to the uncontrolled groups. The differences were significantly greater at 2, 3, and 4 months (P ≤0.001).Conclusions: This study demonstrated that osseointegrated dental implants in insulin‐controlled diabetic rats maintained bone‐to‐implant contacts over a 4‐month period. However, boneto‐ implant contact appears to decrease with time in uncontrolled diabetic rats. J Periodontol 2005;76:621‐626.
Intraoral Autogenous Block Onlay Bone Grafting for Extensive Reconstruction of Atrophic Maxillary Alveolar Ridges
Authors: Schwartz‐Arad Devorah , Levin Liran 
Published: April 2005

Background: Endosseous implants require sufficient bone volume for complete bone coverage. Alveolar defi‐ ciency can prevent ideal implant placement. Local bone grafts are a convenient source of autogenous bone in alveolar reconstruction. The aim of this study was to describe a technique, and to evaluate the success of extensive bone reconstruction of atrophic maxillary alveolar ridges using only intraoral block bone grafts prior to dental implantation.Methods: Files of 10 healthy patients with extensive bone reconstruction of the maxillary alveolar ridge using intraoral block bone graft operations were reviewed. Medical history, smoking status, bone origin (donor sites), number of bone blocks, and complications were recorded.Results: Of the 10 extensive bone maxillary reconstructions, four were uneventful, two required additional bone augmentation at the time of dental implant placement, two had a minimal graft exposure, one had a minor adverse effect (temporary paresthesia), and one operation partially failed and required partial graft removal.Conclusion: Intraoral bone block grafting is a predictable operation with a high success rate for longspan augmentation, up to complete jaw augmentation/ extensive bone reconstruction of the maxillary alveolar ridge.

Interdental Papilla Augmentation Procedure Following Orthodontic Treatment in a Periodontal Patient
Authors: Cardaropoli Daniele , Re Stefania 
Published: April 2005

Background: The absence of the interdental papilla is a situation that may alter patients' esthetics. Recession of interproximal gingival tissues may be a consequence of periodontal disease, but in some cases it may also be a consequence of periodontal therapy, as a result of surgical or non‐surgical procedures.Methods: The authors present a new multidisciplinary approach for the treatment of migrated maxillary incisors presenting infrabony defects, extrusion, and loss of the interdental papilla.Results and Conclusion: The proposed clinical protocol may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level, together with resolution of the periodontal defects.

Single‐column simulated‐moving‐bed process with recycle lag
Authors: Mota José P. B. , Araújo João M. M. 
Published: April 2005

AbstractIt is shown that the periodic state of the simulated‐moving‐bed (SMB) process is reproduced by a single‐column chromatographic process with a recycle lag of (N − 1)τ time units, where N is the number of columns of the equivalent SMB unit and τ is the switching time. The operation of this ideal single‐column process is formulated by selecting an arbitrary column of the SMB and following its operation over a complete cycle. To implement the recycle lag in practice, a special type of plug‐flow tube has been designed. It includes internal elements to make the flow as close as possible to plug flow, and a piston to compensate for the difference between the inlet and outlet flow rates. This is necessary because the recycle lag is not a multiple of the overall cycle duration. The proposed system is a more compact, less‐expensive, and simpler‐to‐operate alternative to the SMB. It avoids the problem of packing reproducibility and the total pressure drop is 1/Nth of that of the equivalent SMB. Depending on the efficiency of the recycle tube, our single‐column process can achieve the same purities as the analogous SMB unit while keeping the specific productivity constant. © 2005 American Institute of Chemical Engineers AIChE J, 2005

AbstractBACKGROUNDAlthough patients with cancer are often accompanied by a relative during medical interviews, to the authors' knowledge little is known regarding the efficacy of communication skills training programs on physicians' communication skills in this context. The objective of the current study was to assess the efficacy of 6 consolidation workshops, 3 hours in length, that were conducted after a 2.5‐day basic training program.METHODSAfter attending the basic training program, physicians were assigned randomly to consolidation workshops or to a waiting list. Training efficacy was assessed through simulated and actual interviews that were recorded on an audio tape at baseline, after consolidation workshops for the consolidation‐workshops group, and 5 months after the end of basic training for the waiting‐list group. Communication skills were assessed according to the Cancer Research Campaign Workshop Evaluation Manual. Patients' and relatives' perceptions of and satisfaction with physicians' communication performance were assessed using a 15‐item questionnaire.RESULTSSixty‐two physicians completed the training program. Compared with physicians who participated to the basic training program, when addressing the patient, physicians who were randomized to the consolidation workshops used more open, open directive, and screening questions (P = 0.011 in simulated patient interviews and P = 0.005 in actual patient interviews) and elicited and clarified psychologic concerns more often (P = 0.006 in simulated patient interviews and P < 0.001 in actual patient interviews). When they addressed the relative, physicians who were randomized to the consolidation workshops gave less premature information (P = 0.032 in simulated patient interviews and P < 0.001 in actual patient interviews). When they addressed the patient and the relative simultaneously, physicians who were randomized to the consolidation workshops used more empathy, educated guesses, alerting to reality, confronting, negotiating, and summarizing (P = 0.003 in simulated patient interviews and P = 0.024 in actual patient interviews). Patients, but not relatives, who interacted with physicians in the consolidation‐workshops group were more satisfied globally with the interviews (P = 0.022).CONCLUSIONSSix 3‐hour consolidation workshops resulted in improved communication skills addressed to patients and to relatives. The current results showed that the transfer of skills addressing relatives' concerns remained limited and that consolidation workshops should focus even more systematically on the practice of three‐person interviews.

Structure‐breaking effects of solvated Rb(I) in dilute aqueous solution—An ab initio QM/MM MD approach
Authors: Hofer Thomas S. , Randolf Bernhard R. , Rode Bernd M. 
Published: April 2005

AbstractStructural properties of the hydrated Rb(I) ion have been investigated by ab initio quantum mechanical/molecular mechanical (QM/MM) molecular dynamics (MD) simulations at the double‐zeta HF quantum mechanical level. The first shell coordination number was found to be 7.1, and several other structural parameters such as angular distribution functions, radial distribution functions and tilt‐ and θ‐angle distributions allowed the full characterization of the hydration structure of the Rb(I) ion in dilute aqueous solution. Velocity autocorrelation functions were used to calculate librational and vibrational motions, ion–ligand motions, as well as reorientation times. Different dynamical parameters such as water reorientation, mean ligand residence time, the number of ligand exchange processes, and rate constants were also analyzed. The mean ligand residence time for the first shell was determined as τ = 2.0 ps. © 2005 Wiley Periodicals, Inc. J Comput Chem 26: 949–956, 2005
Nonaqueous capillary electrophoresis for rapid and sensitive determination of fangchinoline and tetrandrine in Radix Stephaniae tetrandrae and its medicinal preparations

Published: April 2005

AbstractA simple, rapid, and sensitive non‐aqueous capillary electrophoresis procedure with head‐column field‐amplified sample stacking concentration for the analysis of fangchinoline and tetrandrine is established. Optimum separation and stacking conditions were obtained when the sample was injected at 8 kV for 50 s after preliminary pressure injection of ethanol (16.9 kPa) for 0.6 s and separated with the buffer containing 50 mM ammonium acetate, 0.5% (v/v) acetic acid, and 50% (v/v) acetonitrile in methanol medium at 24 kV applied voltage. The analytes were detected by UV at 214 nm. The two bisbenzylisoquinoline alkaloids can be separated within 6 min and quantified with high sensitivity. The detection limits were 0.30 ng mL–1 for fangchinoline and 0.34 ng mL–1 for tetrandrine, which indicated that the sensitivities were at least 1000‐fold enhanced over those reported in the literature as obtained by UV detection. The method was applied to the analysis of fangchinoline and tetrandrine in Radix Stephaniae tetrandrae and its medicinal preparations with good results.
