Flap Thickness as a Predictor of Root Coverage: A Systematic Review
Authors: Hwang Debby , Wang Hom‐Lay 
Published: October 2006

Background: Thick gingival tissue eases manipulation, maintains vascularity, and promotes wound healing during and after surgery. A few recent case reports correlate greater flap thickness to mean and complete root coverage after mucogingival therapy for recession defects. The aim of this systematic review is to appraise the current literature on this subject and to combine existing data to verify the presence of any association between gingival thickness and root coverage outcomes.Methods: Human studies that reported the number and class of recessions, measured flap thickness at a well‐defined location, described the method of root coverage used, followed results for at least 3 months, and detailed mean root coverage underwent review and statistical analysis. Investigations were scored from 1 to 5 based on methodological quality. Weighted gingival thickness and weighted mean root coverage was calculated based on standard error. Statistical analysis used the Mann‐Whitney test, analysis of variance (ANOVA), and linear regression to determine any correlation between a number of factors (i.e., thickness, treatment type, and follow‐up time) and mean and complete root coverage. A significant P value was set at <0.05.Results: Fifteen investigations met the inclusion criteria. All of these reported at least 0.7 mm of flap thickness, although measurement locations varied. Treatment modalities included coronally advanced flap, connective tissue graft, and guided tissue regeneration with and without adjuncts. A significant moderate correlation occurred between weighted flap thickness and weighted mean root coverage and weighted complete root coverage (r = 0.646 and 0.454, respectively). According to Mann‐Whitney analysis, a critical threshold thickness >1.1 mm existed for weighted mean and complete root coverage (P <0.02). The type of treatment rendered also influenced root coverage. Further simple linear regression revealed a high correlation between weighted thickness and weighted mean root coverage in connective tissue grafting and guided tissue regeneration (r = 0.909 and 0.714, respectively) but not coronally advanced flap therapy. Study score and follow‐up time did not affect the percentage of root coverage.Conclusion: Within the limits of this review, a positive association exists between weighted flap thickness and mean and complete root coverage.
Temporary Anchorage Devices for Tooth Movement: A Review and Case Reports
Authors: McGuire Michael K. , Scheyer E. Todd , Gallerano Ronald L. 
Published: October 2006

Background: Temporary anchorage devices (TADs) are immediately loaded miniscrews and osseointegrated palatal implants that are placed to control tooth movement during orthodontic treatment and removed when the treatment is completed. They are a relatively new addition to the dental armamentarium and can be used in some cases to replace traditional orthodontic extraoral appliances. Because placement requires a surgical procedure, orthodontists often refer patients to periodontists for this stage of the overall treatment plan.Methods: The purpose of this article is to introduce TADs to the periodontal community by reviewing their purpose, various systems that are available, indications for use, site selection, and surgical technique. Case reports are included to illustrate this new treatment approach.Results: Placement of osseointegrated implants for restorative purposes is an established procedure in most periodontal offices. Although placement of TADs is a modification of these familiar techniques, most of these devices serve a very different purpose, involving new loading protocols with no expectation of osseointegration in patients usually not receiving concomitant periodontal therapy.Conclusions: Periodontists' knowledge of soft and hard tissue anatomy and their ability to manage soft tissue position them well to collaborate with orthodontists in this multidisciplinary treatment. However, as with every new modality, clinicians need to understand the specific uses and limitations of TADs and work closely with their referring orthodontists in identifying patients for whom miniscrew implants are a viable option. Periodontal practices are based primarily on referrals from dental colleagues, and the concept of periodontists working cooperatively with orthodontists is not new. Including TAD placement among the services periodontists offer provides another opportunity to further this relationship and to establish periodontists as appropriate resources for this segment of orthodontic treatment.
Modernising the Morgan Library
Authors: Merkel Jayne 
Published: October 2006

AbstractRenzo Piano's recent addition to the Pierpont Morgan Library in New York is of interest in its own right because it radically alters the experience at one of the city's most appealing and unique institutions. But it is also worth considering,	Jayne Merkel argues, because Piano is now working on more major museums than any architect in the world. At the Morgan, he subtly transformed a magnificent Renaissance Revival private library into a full‐fledged modern museum with fine facilities for displaying parts of the collection and making its resources available to scholars. The old parts look as magnificent as ever, though they are now somewhat side‐lined. The new parts are strong and elegant. The two are daringly juxtaposed, and the planning for 14,028 square metres (151,000 square feet) of facilities that more than doubles the size of the whole on part of a cramped Manhattan block is skilful.

PTPN22 620W allele is not associated with aplastic anemia
Authors: Graf Solomon A. , Calado Rodrigo T. , Young Neal S. 
Published: October 2006

AbstractThe 1858C/T variant in PTPN22 imparts a gain of function mutation dysregulating T‐cell stimulation and is associated with an array of autoimmune diseases. Using a case‐control design, we compared the frequency of this polymorphism in 91 patients with acquired aplastic anemia to 132 ethnically matched controls. Representation of the PTPN22 variant was not significantly different between the two populations, suggesting that this gene polymorphism does not contribute to the etiology of aplastic anemia. Aplastic anemia thus joins a list of autoimmune diseases that commonly lack a major humoral disease component and do not associate with the PTPN22 variant. Am. J. Hematol., 2006.

AbstractRenal disease is common in sickle cell anemia. In this exploratory work, we used data from a longitudinal study of the natural history of sickle cell disease to examine the hypothesis that polymorphisms (SNPs) in selected candidate genes are associated with glomerular filtration rate (GFR). DNA samples and clinical and laboratory data were available for 1,140 patients with sickle cell anemia. GFR was estimated using the Cockcroft–Gault and Schwartz formulas for adults and children, respectively. We examined ∼175 haplotype tagging (ht) SNPs in about 70 genes of the TGFβ/BMP pathway for their association with GFR using linear regression. Four SNPs in BMPR1B, a bone morphogenetic protein (BMP) receptor gene, yielded statistically significant associations (P values ranging from 0.015 to 0.046). Three haplotypes in this gene were also associated with GFR. The TGF‐β/BMP pathway has been associated with the development of diabetic nephropathy, which has some features in common with sickle cell nephropathy. Our results suggest that, as with other subphenotypes of sickle cell disease, renal function may be genetically modulated. Am. J. Hematol., 2007. © 2006 Wiley‐Liss, Inc.
Retrochorionic hematoma in congenital afibrinogenemia: Resolution with fibrinogen concentrate infusions

AbstractWithout treatment, pregnancies in patients with congenital afibrinogenemia terminate in miscarriage at 5–6 weeks of gestation. Animal model studies have suggested that implantation site bleeding contributes to miscarriage in afibrinogenemia; however, retrochorionic hematoma in human congenital afibrinogenemia has not been previously observed. A patient with congenital afibrinogenemia receiving fibrinogen prophylaxis developed a retrochorionic hematoma in the first trimester. With continuous intensified fibrinogen concentrate replacement the hematoma resolved over 6 weeks, and the patient delivered a healthy infant. Median fibrinogen levels in the first trimester were 48 mg/dL and in second and third trimester 44 mg/dL. Median fibrinogen levels under 60 mg/dL may be adequate to maintain pregnancy in patients with congenital afibrinogenemia, although it is possible that higher levels might reduce the risk of hemorrhagic events.

Lipidated Ras and Rab Peptides and Proteins—Synthesis, Structure, and Function
Authors: Brunsveld Luc , Kuhlmann Jürgen , Alexandrov Kirill , Wittinghofer Alfred , Goody Roger S. , Waldmann Herbert 
Published: October 2006

AbstractChemical biology can be defined as the study of biological phenomena from a chemical approach. Based on the analysis of relevant biological phenomena and their structural foundation, unsolved problems are identified and tackled through a combination of chemistry and biology. Thus, new synthetic methods and strategies are developed and employed for the construction of compounds that are used to investigate biological procedures. Solid‐phase synthesis has emerged as the preferred method for the synthesis of lipidated peptides, which can be chemoselectively ligated to proteins of the Ras superfamily. The generated peptides and proteins have solved biological questions in the field of the Ras‐superfamily GTPases that are not amendable to chemical or biological techniques alone.

Published: October 2006

AbstractThe anatomy of the mammalian tongue consists of an intricate array of variably aligned and extensively interwoven muscle fibers. As a result, it is particularly difficult to resolve the relationship between the tongue's microscopic anatomy and tissue‐scale mechanical function. In order to address this question, we employed a method, diffusion spectrum imaging (DSI) with tractography, for displaying the macroscopic orientational properties of the tissue's constituting myofibers. DSI measures spatially variant proton displacement for a given 3D imaging segment (voxel), reflecting the principal orientation(s) of its myofibers. Tractography uses the angular similarity displayed by the principal fiber populations of multiple adjacent voxels to generate tract‐like structures. DSI with tractography thus defines a unique set of tracts based on the net orientational behavior of the myofiber populations at different positions in the tissue. By this approach, we demonstrate a novel myoarchitectural pattern for the bovine tongue, consisting of short and orthogonally aligned crossing fiber tracts in the intrinsic core region, and longer, parallel‐aligned fiber tracts on the tissue margins and in the regions of extrinsic fiber insertion. The identification of locally aligned myofiber populations by DSI with tractography allows us to reconsider lingual anatomy, not in conventional microscopic terms, but as a set of heterogeneously aligned and macroscopically resolved myofiber tracts. We postulate that the properties associated with these myofiber tracts predict the mechanical behavior of the tissue and thus constitute a method to relate structure and function for anatomically complex muscular tissues.

Bilateral tibial hemimelia I
Authors: Suganthy J. , Rassau Marina , Koshi Rachel , Battacharjee Suranjan 
Published: October 2006

AbstractCongenital absence of tibia is a rare anomaly. We report a case of bilateral tibial hemimelia born to phenotypically normal parents. The two amputated legs with tibial dysplasia obtained from a 3‐year‐old boy were studied by radiography and anatomical dissection. The radiological evaluation revealed a normal hip joint. The lower end of femur was normal without any bifurcation, shortening or bowing. Fibula was present on both legs and there was no sign of bowing or doubling. Both right and left tibiae were absent. In addition, on the right side, five tarsal bones, two metatarsals and the corresponding digital rays were absent. On the left side, three tarsal bones were absent. Dissection of the amputated segments showed the presence of extensor digitorum longus, peroneus tertius, peroneus longus and brevis, gastrocnemius, and soleus. Following bilateral knee disarticulation the patient was fitted with prosthesis and is doing well. Clin. Anat. 20:460–464, 2007. © 2006 Wiley‐Liss, Inc.
Aromaticity of Tri‐ and Tetranuclear Metal–Carbonyl Clusters Based on Magnetic Criteria
Authors: Corminboeuf Clémence , Schleyer Paul von Ragué , King R. Bruce 
Published: October 2006

AbstractRecently, the σ‐aromaticity model proposed for cyclopropane by Dewar was employed to account for the stability of Group 8 trinuclear metal–carbonyl compounds [M3(CO)12] (M=Fe, Ru, Os). This paper further examines this hypothesis and provides the first quantitative evidence for the σ‐aromatic/antiaromatic nature of the [M3(CO)12]/[M4(CO)16] species based on structural and nucleus‐independent chemical‐shift analysis. In addition, the extent of electron delocalization in tetrahedral [M4(CO)14] and butterfly [M4(CO)15] is analyzed and compared to prototype cycloalkanes. While remarkable analogies exist between metal–carbonyls and cycloalkanes, transition metals provide additional overlap possibilities that affect both the ring strain and the magnetic properties of metal–carbonyl rings and cages.

Fabrication of low‐field water‐cooled resistive magnets for small animal magnetic resonance imaging
Authors: Gilbert K.M. , Dalrymple B. , Handler W.B. , Scholl T.J. , Chronik B.A. 
Published: October 2006

AbstractThere are many nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) techniques that employ resistive magnets. Resistive magnets are particularly useful for low‐field (<0.5 T) imaging and for applications involving the cycling of magnetic fields. This article discusses a general technique for the fabrication of resistive magnets that can be used in small animal MR imaging. A detailed discussion is given of the magnet winding technique, the forced‐water cooling system design and construction, and the support structure. Two examples are given of resistive systems built by the authors. © 2006 Wiley Periodicals, Inc. Concepts Magn Reson 29B: 168–175, 2006.
