Asymmetric Nash Bargaining with Surprised Players
Authors: Hanany Eran , Gal Rotem
Published: August 2007

This paper introduces two-player bargaining problems allowing for asymmetric subjective uncertainty about factors that determine whether agreement is achieved, focusing on surprising events, i.e. events believed possible by only one player. A `subjective Nash' solution is proposed, in which a bargaining outcome is defined as immune to all possible appeals given the subjective uncertainty of disagreement. In addition to Pareto optimality and independence of irrelevant alternatives, the main axiom in the solution characterization is `subjective symmetry'. The solution is shown to be equivalent to a specific, non-symmetric, Nash solution, with preference dependent weights that equal the subjective probability players assign to the intersection of their belief supports.
Complications during Mandibular Midline Distraction
Authors: von Bremen Julia , Schäfer Dominik , Kater Wolfgang , Ruf Sabine
Published: August 2007

Objective: To analyze the number and type of complications during mandibular midline distraction.

Materials and Methods: The records of 100 consecutive patients who underwent mandibular midline distraction were evaluated, and complications which occurred up to 2 weeks after surgery were recorded.

Results: Fourteen patients had complications during the distraction period. In four cases the screw of the appliance rotated back between the activations. In three cases the osteotomy had to be repeated because the symphysis did not open; two cases developed scar strictures, in another two a lower incisor fractured. One case developed an abscess, one a mandibular swelling, and one a large gingival recession.

Conclusions: Complications during or shortly after mandibular midline distraction surgery are relatively rare and mostly mild or transient. Only 3% of the patients presented irreversible damage. Thus, mandibular midline distraction appears to be a relatively safe method of expanding the mandible.
Temporal Expression of SOX9 and Type II Collagen in Spheno-Occipital Synchondrosis of Mice after Mechanical Tension Stimuli
Authors: Cendekiawan Teddy , Wong Ricky W. K. , Rabie A. Bakr M.
Published: August 2007

Objective: To associate the expressions of SOX9 and type II collagen during growth in the synchondrosis with and without tensile stress in order to understand the role of these factors in the growth of cartilage in spheno-occipital synchondrosis.

Materials and Methods: Sixty 1-day-old male BALB/c mice were randomly divided into experimental and control groups. Each group was subdivided again into five different time points which were 6, 24, 48, 72, and 168 hours. Each subgroup consisted of five mice. Each mouse was sacrificed using an overdose of pentobarbitone sodium. The synchondroses were aseptically removed and incubated in a 24-well plate with or without tensile stress in tissue culture. Tissue sections were stained immunohistochemically to quantitatively analyze the expression of SOX9 and type II collagen.

Results: There was a statistically significant increase of 57% (P < .001) in the expression of SOX9 between the experimental and control groups at 24 hours, followed by a significant increase of 44.4% (P < .001) in the expression of type II collagen at 72 hours.

Conclusions: SOX9 may play an important role for early differentiation of chondrocytes and increase the expression of type II collagen, a major component of the extracellular matrix, during the growth of cartilage in the spheno-occipital synchondrosis.

Authors: Onyeaso Chukwudi Ochi , Isiekwe Michael Chukwudi
Published: August 2007

Objective: To evaluate longitudinally the occlusal changes between the deciduous and early mixed dentition stages in Nigerian children.

Materials and Methods: The occlusion of 145 3- to 5-year-old children was initially assessed at a popular pre-primary school center in Ibadan, Nigeria in October 2002, using the Foster and Hamilton criteria. The same group of children was followed up for reexamination in October 2006 in the primary school section of the center. Of 61 students who were located and reexamined, 54 (26 male and 28 female) qualified for the study. The molar relationship was assessed using Angle classification, and other occlusal features such as spacing, crowding, overbite, and overjet were also assessed. Descriptive statistics, chi-square test, as well as Pearson correlation coefficient, were applied as appropriate in the analysis of the data.

Results: Of 32 subjects initially having a flush terminal relationship (Class 1), 22 (68.7%) resulted in a Class I molar relationship, seven (21.9%) had Class II, and three (9.4%) had asymmetric relationships. Mesial step (Class III) was formed initially in 18 and 11 (61.1%) resulted in Class I. A Class III developed in five (27.8%). Significant positive correlations were found for molar relationship, crowding, overbite, and overjet variables (P < .01) between the two periods of assessments, but all were below 0.7 value.

Conclusions: Angle Class I molar relationship was favored by initial flush terminal plane and mesial step relationships in the deciduous dentition.

Authors: Bishara Samir E. , Soliman Manal , Laffoon John F. , Warren John
Published: August 2007

Objective: To determine the shear bond strength of a new resin glass ionomer adhesive with higher fluoride release properties when bonding orthodontic brackets.

Materials and Methods: Sixty freshly extracted human molars were collected and stored in a solution of 0.1% (weight/volume) thymol. The teeth were cleaned and polished. The teeth were randomly separated into three groups according to the enamel conditioner/etchant and adhesive used. Group I: 20 teeth conditioned with 10% polyacrylic acid and brackets bonded with the new glass ionomer adhesive. Group II: 20 teeth conditioned with 37% phosphoric acid and brackets bonded with the new glass ionomer adhesive. Group III (control): 20 teeth etched with 37% phosphoric acid and brackets bonded with a composite adhesive.

Results: The results of the analysis of variance comparing the three experimental groups (F = 10.294) indicated the presence of significant differences between the three groups (P = .0001). The shear bond strengths were significantly lower in the two groups bonded with the new glass ionomer adhesive whether conditioned with polyacrylic acid (x̄ = 3.2 ± 1.8 MPa) or phosphoric acid (x̄ = 2.3 ± 1.1 MPa), while the mean shear bond strength of the composite adhesive was 5.2 ± 2.9 MPa.

Conclusions: Although the increased fluoride release from the new glass ionomer has the potential of decreasing decalcification around orthodontic brackets, the shear bond strength of the material is relatively low.
Gene Therapy to Enhance Condylar Growth Using rAAV-VEGF
Authors: Dai Juan , Rabie A. Bakr M.
Published: August 2007

Objective: To test the hypothesis that the introduction of specific vascular growth inducting genes would favorably affect mandibular condylar growth in Sprague-Dawley (SD) rats over a limited experimental period. Therefore, the aim of this study is to examine the effect of gene therapy on condylar growth by means of a morphological assessment.

Materials and Methods: Ninety 35-day-old female SD rats were randomly divided into three groups, which received any of the injections of recombinant adeno-associated virus mediated vascular endothelial growth factor (rAAV-VEGF), rAAV mediated enhanced green fluorescence protein (rAAV-eGFP), or phosphate-buffered saline (PBS) into both mandibular condyles. Each group of rats was sacrificed on the following experimental days: 7, 14, 21, 30, and 60. Left halves of the mandibles were isolated and digital pictures were obtained in a standardized manner.

Results: The length of condylar process (B-F) as well as mandibular length (A-F) significantly increased on day 30 and continued to increase until the end of the experiment. Moreover, the width of condyle (Q-R) had increased significantly from day 30 and lasted to day 60. Condylar length (C-D) was found to be significantly longer on day 60.

Conclusions: Gene therapy with VEGF stimulates condylar growth at will. The rAAV-VEGF is an excellent candidate for future gene therapy to induce mandibular growth.

Authors: Sakai Yuichi , Kuroda Shingo , Murshid Sakhr A. , Takano-Yamamoto Teruko
Published: August 2007

A female patient with a skeletal Class III severe anterior openbite was treated using miniplates as the anchorage. The patient was 15 years and 10 months of age when she reported to our university hospital with a chief complaint of anterior openbite and reversed occlusion. The patient had an anterior openbite with an overjet of −3.0 mm and overbite of −5.0 mm and a Class III molar relationship. The cephalometric analysis showed a skeletal Class III relationship (ANB 0°). After the extraction of the bilateral mandibular third molars, miniplates were placed in the mandibular external oblique line. The mandibular dentition was retracted using elastic chain and miniplates. After treatment, an Angle Class I molar relationship was achieved and overjet and overbite had become 2.0 mm and 1.5 mm. A good facial appearance and occlusal relationship were obtained. The total active orthodontic treatment period was 23 months. Wrap-around type retainers were placed on both jaws and a lingual bonded retainer was also attached in the mandibular incisors. After 1 year of retention, the occlusion was stable, and a good facial profile was also retained. The mandibular deviation to the left was improved and the strain in the circumoral musculature during lip closure disappeared. An appropriate interincisal relationship was achieved by the uprighting of mandibular dentition without changing the vertical intermaxillary relationship. A panoramic radiograph showed no marked root resorption. Our results suggest that implant anchorage is useful for correction of skeletal Class III severe anterior openbite cases.

Authors: Altug-Atac Ayse Tuba , Bolatoglu Halise , Memikoglu Ufuk Toygar
Published: August 2007

Objective: To determine the changes in the position and area of nasal and labial soft tissues in adult skeletal Class III patients who underwent bimaxillary orthognathic surgery.

Materials and Methods: Pretreatment (T1), preoperative (T2), and posttreatment (T3) cephalometric variables and upper-lower lip areas were measured on lateral cephalometric radiographs for 20 individuals (9 male, 11 female; mean age 21.3 years at T1, 22.4 years at T2, and 23.4 years at T3) who had maxillary advancement and mandibular setback. Analysis of variance (ANOVA) and Duncan tests were used to compare the cephalometric and area measurements at the beginning of treatment, and at presurgery and postsurgery, respectively. Paired t-tests were also performed to analyze changes within the periods.

Results: The tip of the nose was affected less with the movement of the underlying skeletal structure (0.25%), while the soft tissue B point (B′) moved equally with the skeletal B point. As the maxilla related variables increased due to the forward movement, the upper labial areas decreased. With the backward movement of the mandible, the middle and inferior lower labial areas increased, while the superior lower labial area decreased.

Conclusions: The results of our study suggest that the dramatic improvement in the facial profiles of the bimaxillary surgery patients is primarily related to the backward movement of the mandible and the significant reduction in the superior lower lip area.

Authors: Pereira Cássio Vicente , Kaminagakura Estela , Bonan Paulo Rogério Ferreti , Bastos Renata Avelar , Pereira Luciano José
Published: August 2007

Objective: To determine the immune response related to nickel and nickel-free orthodontic appliances using cellular (total and differential leukocytes) and humoral (IgA) quantification.

Materials and Methods: Thirty-five Wister rats were randomly distributed into three groups (A, B, and C). In the A group, the animals were subdivided into three subgroups (A1: control, without brackets; A2: nickel-free brackets; and A3: nickel brackets) with seven animals in each group; the animals were sacrificed after 14 days. Groups B and C received only nickel brackets and were kept for 14 days. After this period, the implants were removed and the rats were sacrificed. In group B, the animals were sacrificed 2 days after the appliance removal (16 days in total); and in group C, the animals were sacrificed 7 days after the brackets removal (21 days in total). Total and differential leukocyte number, IgA quantification and histopathologic analysis were done. Histopathologic analysis of subcutaneous tissue related to the orthodontic brackets was done as well.

Results: There were significant differences between the number of leukocytes for the nickel-implanted animals and the nickel-free and control groups after 14 days of implantation (P < .05). However, there was no significant difference among groups A1, A2, and A3 for the differential number of leukocytes and for the IgA quantification, except for the number of monocytes, which was three times higher in the nickel group (A3). The histopathologic findings did not show differences between groups.

Conclusions: Nickel did not promote significant adverse biological effects.
Strain Mapping at the Atomic Scale in Highly Mismatched Heterointerfaces
Authors: Sánchez A. M. , Lozano J. G. , García R. , Herrera M. , Ruffenach S. , Briot O. , González D.
Published: August 2007

A complete characterization of dislocation network in a highly mismatched interface with high spatial resolution has been performed. The interface between InN quantum dots and a (0001) GaN substrate contains three noninteracting sets of regularly‐spaced misfit dislocations lying along <110> directions. The network has a “Star of David” form, with each star bounding a hexagonal region which is pseudomorphic. These misfit dislocations form a threading dislocation network at the island edges due to free surface forces.
Collective Response from a Cationic Tetrahedral Fluorene for Label‐Free DNA Detection
Authors: Liu B. , Dan T. T. T. , Bazan G. C.
Published: August 2007

A cationic water‐soluble tetrahedral molecule bearing four phenylene‐bis(fluorene) optical units, namely tetrakis[4‐(2‐(9,9,9′,9′‐tetrakis(N,N,N‐trimethylammoniumhexyl)‐7,2′‐bifluorenyl))‐phenyl]methane hexadecanebromide, was designed and synthesized. Fluorescence resonance energy transfer (FRET) experiments between the tetrahedral molecule and fluorescein‐labeled double stranded DNA (dsDNA‐Fl) or single stranded DNA (ssDNA‐Fl) were undertaken. Due to its specific shape and spatial registry, the tetrahedral molecule shows improved FRET efficiencies to dsDNA‐Fl as well as improved selectivity between dsDNA and ssDNA, when compared to a cationic conjugated polymer with similar repeat units. 30‐Fold signal amplification for dsDNA/ethidium bromide (EB) and selective response between complementary and non‐complementary DNA indicates that tetrahedral molecules could be useful to amplify the optical response from EB‐based DNA protocols.

Published: August 2007

Erbium quinolinolates, commonly assumed to be mononuclear species with octahedral co‐ordination geometry, have been proposed as promising materials for photonic devices but difficulties in obtaining well defined products have so far limited their use. We report here the conditions to obtain in high yields three different kinds of pure neutral erbium quinolinolates by mixing an erbium salt with 8‐quinolinol (HQ) and 5,7‐dihalo‐8‐quinolinol (H5,7XQ: X = Cl and Br): i) the trinuclear complex Er3Q9 (1) which is obtained with HQ deprotonated by NH3 in water or ethanol/water mixtures; ii) the already known dimeric complexes based on the unit [Er(5,7XQ)3(H2O)2] [X = Cl (2) and Br (3)]; iii) the mononuclear [Er(5,7XQ)2(H5,7XQ)2Cl] [X = Cl (4) and Br (5)] complexes, obtained in organic solvents without base addition, where the ion results coordinated to four ligands, two deprotonated chelating, and two as zwitterionic monodentate oxygen donors. These results represent a further progress with respect to a recent reinvestigation on this reaction, which has shown that obtaining pure and anhydrous octahedral ErQ3, the expected reaction product, is virtually impossible, but failed in the isolation of 1 and of the neutral tetrakis species based on H5,7XQ ligands. Structural data provide a detailed description of the molecules and of their packing which involves short contacts between quinoxaline ligands, due to π–π interactions. Electronic and vibrational studies allow to select the fingerprints to distinguish the different products and to identify the presence of water. The structure/property relationship furnishes a satisfactory interpretation of the photo‐physical properties. Experimental evidence confirms that the most important quenchers for the erbium emission are the coordinated water molecules and shows that the ligand emission is significantly affected by the π–π interactions.
Azathioprine‐associated acute myeloid leukemia in a patient with Crohn's disease and thiopurine S‐methyltransferase deficiency
Authors: Yenson Paul R. , Forrest Donna , Schmiegelow Kjell , Dalal Bakul I.
Published: August 2007

Immunosuppressive thiopurines like azathioprine, 6‐mercaptopurine, and thioguanine are commonly used in inflammatory and neoplastic disorders. A subset of these patients are genetically slow metabolizers due to point‐mutations in enzyme thiopurine S‐methyltransferase (TPMT), and are at a higher risk of hematologic toxicity and leukemogenesis. We present such a patient who was a slow metabolizer for azathioprine, and developed a rapidly lethal form acute myeloid leukemia after relatively low dose exposure to the drug. There was prominent hemophagocytic activity in the bone marrow, and cytogenetic analysis showed a complex karyotype with monosomy 7, but no involvement of chromosome 8. Am. J.

Dynamic reaction inside co‐rotating twin screw extruder. I. Truck tire model material/polypropylene blends
Authors: Lee Sung Hyo , Balasubramanian Maridass , Kim Jin Kuk
Published: August 2007

Waste ground rubber tire (WGRT) is a complex composite containing various elastomers, carbon black, zinc oxide, stearic acid, processing oils, and other curatives. Most of the waste ground rubber tire is composed of mainly natural rubber (NR) and styrene butadiene rubber (SBR) in varying proportions. Blending it with other thermoplastic materials is difficult due to the inherent thermodynamic incompatibility. But, the compatibility can be increased by making the reactive sites in WGRT with suitable chemicals under optimum condition of shearing inside a twin screw extruder and it is said to undergo a dynamic reaction inside the extruder. To understand the mechanism of dynamic reaction process of a rubber/polyolefin blend, the blending of a truck tire model material rubber with polyolefin was first tried before it was applied to waste WGRT material. It was observed that the blends of a truck tire model rubber material and PP thermoplastic are physical mixture of two incompatible polymers in which a continuous plastic phase is largely responsible for the tensile properties. The rubber particles are the dispersed phase. The large particle size and the poor adhesion of these rubber particles are believed to be liable for the poor tensile properties. In case of blends of truck tire model material with isotactic polypropylene the tensile properties are found to be lower than that of its PP‐g‐MA counterpart which can be attributed to the reaction of the MA with the carbon black particles. A schematic representation of the possible interactions has been proposed. The effect of addition of compatibilizers such as SEBS and SEBS‐g‐MA has also been studied. The tensile and TGA studies indicate that the polarity of SEBS and SEBS‐g‐MA induces an increase in the performance characteristics for both types of polyolefins but the intensity of this increase is higher in the PP‐g‐MA based blends. © 2007 Wiley Periodicals, Inc.

Authors: Zhang Youchun , Broekhuis A. A. , Picchioni F.
Published: August 2007

Aqueous polymer emulsions were prepared by chemical modifications of thermosetting alternating polyketones in a one‐pot reaction. Polymeric amines derived from the polyketones can act as polymeric surfactants for the self‐emulsification of polyketones. The stability and structure of the emulsions with respect to the storage time at room temperature (20°C) at different experimental conditions were thoroughly studied by dynamic light scattering, rheology and Cryo‐SEM. Emulsions with an average particle size smaller than 1 μm and a viscosity less than 1 Pa·s could be achieved and remained stable for at least 1‐year. The prepared emulsions were qualified as wood adhesives for wood composite industry, according to the European Standard for wood adhesive testing. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Patient factors influencing conversion from laparoscopically assisted to open surgery for colorectal cancer
Authors: Thorpe H , Jayne D G , Guillou P J , Quirke P , Copeland J , Brown J M
Published: August 2007

Background

Intraoperative conversion from laparoscopically assisted to open surgery for colorectal cancer is thought to be influenced by several patient factors. Analysis of the Conventional versus Laparoscopic-Assisted Surgery In Colorectal Cancer (CLASICC) Trial data aimed to identify these risk factors.

Methods

Of 488 laparoscopically assisted procedures attempted, 143 (29·3 per cent) were converted to open operation. Patient factors considered in multivariable analyses were age, sex, previous abdominal incisions, body mass index (BMI), tumour site, tumour diameter, pathological tumour (pT) and pathological node (pN) stage, extent of tumour spread from the muscularis propria, liver and peritoneal metastases, and American Society of Anesthesiologists (ASA) grade. As BMI was missing for 30·7 per cent of patients, two approaches were employed: one considered BMI as a possible risk factor and one did not.

Results

When BMI was taken into consideration, male sex (odds ratio (OR) 2·07; P = 0·020), BMI (OR 1·10; P = 0·006) and extent of tumour spread from the muscularis propria (OR 1·08; P < 0·001) were independent predictors of conversion. When BMI was not considered, extent of tumour spread (OR 1·07; P < 0·001) and male sex (OR 2·05; P = 0·004) were again identified, as were tumour site (OR 2·11; P = 0·005) and ASA grade (II versus I, OR 0·92; III versus I, OR 2·74; P = 0·012).

Conclusion

Intraoperative conversion is more likely with larger BMI, in men, patients with rectal cancer, those graded ASA III or when there is greater local tumour spread.
Early Barriers in the Matrix Photochemical Formation of syn–anti Randomized FC(O)SeF from the OCSe:F2 Complex

Published: August 2007

The photochemically induced reaction of OCSe and F2, isolated together in an Ar matrix at about 15 K, leads to formation of the hitherto‐unknown fluorocarbonylselenyl fluoride FC(O)SeF. The reaction occurs via a van der Waals complex OCSe⋅⋅⋅FF that favors very early formation of the anti conformer. The presence and subsequent decay of a band assigned to the FF vibration correlated with perturbed OCSe bands seems to confirm this hypothesis. Subsequent irradiation of the matrix leads to randomized FC(O)SeF by a photochemically induced conformational equilibrium between syn and anti forms. Another photochemical reaction channel is the formation of CO and SeF2 molecules, which are produced in the same matrix cage and then form a loose complex. The changes were monitored and the products characterized experimentally by their IR spectra, and the spectra analyzed in the light of the results of theoretical calculations.
