c‐Abl is required for the signaling transduction induced by L‐selectin ligation
Authors: Chen Cuixia , Shang Xin , Xu Ting , Cui Lingling , Luo Jixian , Ba Xueqing , Hao Shui , Zeng Xianlu 
Published: October 2007

AbstractLymphocyte recruitment onto inflamed tissues requires cells tethering to and rolling on vascular surfaces under flow. L‐selectin is constitutively expressed on leukocytes to mediate the leukocytes’ initial capture and subsequent rolling along the vessel. Apart from its adhesive function, engagement of L‐selectin also results in cell activation, which is related to the completed signaling transduction. Here we show that ligation of L‐selectin with its mAb increases c‐Abl kinase activity, and that the activated c‐Abl kinase can be recruited to and phosphorylate the cytoplasmic domain of L‐selectin. In addition, the activated c‐Abl kinase can regulate Zap70 kinase by increasing the phosphorylation of the Y319 site of Zap70 kinase and connect with Zap70 kinase through its SH2 domain. These results indicate that c‐Abl kinase plays an important role in accepting and transferring the upstream activation events induced by L‐selectin ligation.
On an efficient solution strategy of Newton type for implicit finite element schemes based on algebraic flux correction
Authors: Möller Matthias 
Published: October 2007

AbstractA discrete Newton approach is applied to implicit flux‐limiting schemes based on the concept of algebraic flux correction. The Jacobian matrix is approximated by divided differences and assembled edge by edge. The use of a nodal flux limiter leads to an extended stencil which can be constructed a priori. Numerical examples for 2D benchmark problems are presented to compare the performance of the algebraic Newton method with the defect correction approach. Copyright © 2007 John Wiley & Sons, Ltd.
Social capital as a mediating factor in emergency preparedness and concerns about terrorism
Authors: Hausman Alice J. , Hanlon Alexandra , Seals Brenda 
Published: October 2007

AbstractThe purpose of this study was to investigate how social capital might be instrumental in mediating concerns about terrorism and promoting appropriate responses for emergency preparedness. Results are presented from a random‐digit dialed survey of a metropolitan area measuring individual characteristics as well as community‐level characteristics as possible predictors of the practice of emergency preparedness and concerns about future terrorism. Results show that social capital is positively associated with increased preparedness and with increased concern about future terrorism events. The authors suggest that the information sharing and norm‐setting processes related to high social capital help set the stage for both increased awareness of the consequences of terrorism and the value of increased preparedness. © 2007 Wiley Periodicals, Inc.

Relationships with adults as predictors of substance use, gang involvement, and threats to safety among disadvantaged urban high‐school adolescents
Authors: Ryan Linda G. , Miller‐Loessi Karen , Nieri Tanya 
Published: October 2007

AbstractUsing a resilience framework, the authors examined the protective effects of parental support, self‐disclosure to parents, parent‐initiated monitoring of adolescent behavior, and relationships with school personnel on three critical problems of adolescents: substance use, gang involvement, and perceived threats to safety at school. The sample consisted of 342 ethnically diverse high‐school students in an economically disadvantaged urban area in the southwestern United States. The regression analyses controlled for academic performance, poor anger management, risk‐seeking propensities, co‐occurring substance use, and co‐occurring gang involvement. Interactions as well as main effects were examined. The specific protective roles of all four adult relationships were identified with respect to problematic outcomes. Adolescent self‐disclosure to parents, a variable rarely examined in resilience research, was associated with less chance of substance use for two high‐risk groups: those already involved with gangs, and those with high risk‐seeking tendencies. © 2007 Wiley Periodicals, Inc.

AbstractPercutaneous ethanol injection (PEI) is an option for hepatocellular carcinoma (HCC) treatment that is most effective for solitary lesions ≤5 cm or multiple lesions ≤3 cm. Malignant seeding along the needle tract is a rare complication of the procedure. We report a case of tumor seeding along the needle tract following PEI treatment for HCC arising 21 months after treatment. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2008
Development of the dermal skeleton in Alligator mississippiensis (Archosauria, Crocodylia) with comments on the homology of osteoderms
Authors: Vickaryous Matthew K. , Hall Brian K. 
Published: October 2007

AbstractThe dermal skeleton (= exoskeleton) has long been recognized as a major determinant of vertebrate morphology. Until recently however, details of tissue development and diversity, particularly among amniotes, have been lacking. This investigation explores the development of the dermatocranium, gastralia, and osteoderms in the American alligator, Alligator mississippiensis. With the exception of osteoderms, elements of the dermal skeleton develop early during skeletogenesis, with most initiating ossification prior to mineralization of the endoskeleton. Characteristically, circumoral elements of the dermatocranium, including the pterygoid and dentigerous elements, are among the first to form. Unlike other axially arranged bones, gastralia develop in a caudolateral to craniomedial sequence. Osteoderms demonstrate a delayed onset of development compared with the rest of the skeleton, not appearing until well after hatching. Osteoderm development is asynchronous across the body, first forming dorsally adjacent to the cervical vertebrae; the majority of successive elements appear in caudal and lateral positions. Exclusive of osteoderms, the dermal skeleton initiates osteogenesis via intramembranous ossification. Following the establishment of skeletal condensations, some preossified spicules become engorged with many closely packed clusters of chondrocyte‐like cells in a bone‐like matrix. This combination of features is characteristic of chondroid bone, a tissue otherwise unreported among nonavian reptiles. No secondary cartilage was identified in any of the specimens examined. With continued growth, dermal bone (including chondroid bone) and osteoid are resorbed by multinucleated osteoclasts. However, there is no evidence that these cells contribute to the rugose pattern of bony ornamentation characteristic of the crocodylian dermatocranium. Instead, ornamentation develops as a result of localized concentrations of bone deposited by osteoblasts. Osteoderms develop in the absence of osteoblastic cells, osteoid, and periosteum; bone develops via the direct transformation of the preexisting dense irregular connective tissue. This mode of bone formation is identified as metaplasia. Importantly, it is also demonstrated that osteoderms are not histologically uniform but involve a range of tissues including calcified and uncalcified dense irregular connective tissue. Between taxa, not all osteoderms develop by homologous processes. However, it is concluded that all osteoderms may share a deep homology, connected by the structural and skeletogenic properties of the dermis. J. Morphol., 2008. © 2007 Wiley‐Liss, Inc.

Authors: O'Neill Anne C. , Winograd Jonathan M. , Zeballos José L. , Johnson T. Shane , Randolph Mark A. , Bujold Kenneth E. , Kochevar Irene E. , Redmond Robert W. 
Published: October 2007

AbstractBackground and ObjectivesPhotochemical tissue bonding (PTB) combines photoactive dyes with visible light to create fluid‐tight seals between tissue surfaces without causing collateral thermal damage. The potential of PTB to improve outcomes over standard of care microsurgical reanastomoses of blood vessels in ex vivo and in vivo models was evaluated.Study DesignThe mechanical strength and integrity of PTB and standard microsurgical suture repairs in ex vivo porcine brachial arteries (n = 10) were compared using hydrostatic testing of leak point pressure (LPP). Femoral artery repair in vivo was measured in Sprague–Dawley rats using either standard microvascular sutures (n = 20) or PTB (n = 20). Patency was evaluated at 6 hours (n = 10) and 8 weeks post‐repair (n = 10) for each group.ResultsPTB produced significantly higher LPPs (1,100± 150 mmHg) than suture repair (350±40 mmHg, P<0.001) in an ex vivo study. In an in vivo study all femoral arteries in both suture and PTB repair groups were patent at 6 hours post‐repair. At 8 weeks post‐repair the patency rate was 80% for both groups. No evidence of aneurysm formation was seen in either group and bleeding was absent from the repair site in the PTB‐treated vessels, in contrast to the suture repair group.ConclusionPTB is a feasible microvascular repair technique that results in an immediate, mechanically robust bond with short‐ and long‐term patency rates equal to those for standard suture repair.

AbstractBackground and ObjectivesOptical coherence tomography (OCT) is a depth resolved imaging modality that may aid in identifying sun damaged skin and the precancerous condition actinic keratosis (AK).Study Design/Materials and MethodsOCT images were acquired of 112 patients at 2 sun protected and 2 sun exposed sites, with a subsequent biopsy. Each site received a dermatological evaluation, a histological diagnosis, and a solar elastosis (SE) score. OCT images were examined visually and statistically analyzed.ResultsCharacteristic OCT image features were identified of sun protected, undiseased, sun damaged, and AK skin. A statistically significant difference (P<0.0001) between the average attenuation values of skin with minimal and severe solar elastosis was observed. Significant differences (P<0.0001) were also found between undiseased skin and AK using a gradient analysis. Using image features, AK could be distinguished from undiseased skin with 86% sensitivity and 83% specificity.ConclusionOCT has the potential to guide biopsies and provide non‐invasive measures of skin sun damage and disease state, possibly increasing efficiency of chemopreventive agent trials.

Radiotherapy to the salivary glands as treatment of sialorrhea in patients with parkinsonism
Authors: Postma Anna‐Gerlind , Heesters Mart , van Laar Teus 
Published: October 2007

AbstractThis study investigated retrospectively the long‐term efficacy and safety of radiotherapy (RT) to the major salivary glands as treatment of sialorrhea in patients with parkinsonism. Twenty‐eight patients received a bilateral dose of 12 Gy to the parotid and part of the submandibular glands between 2001 and 2006. Severity of sialorrhea and adverse events were assessed at 1 and 6 months post‐RT and finally in the first quarter of 2007. Item 6 of the activities of daily living‐section of the Unified Parkinson's Disease Rating Scale was used as primary endpoint. Quality of life (QoL) pre‐ and post‐RT was investigated using a shortened Parkinson's Disease Questionnaire‐8. Sialorrhea had improved significantly at 1 month post‐RT and this effect was maintained for at least 1 year. Most frequent adverse events were loss of taste and a dry mouth; however, 75% of these adverse events were transient. QoL had improved significantly on the long term. The clinical global impression scores at the final follow‐up showed that 80% of patients were satisfied. It was concluded that RT is an effective and safe treatment of sialorrhea on the long term in patients with parkinsonism. © 2007 Movement Disorder Society
Parkinson's disease and aging: Same or different process?
Authors: Hawkes Christopher H. 
Published: October 2007

AbstractParkinson's disease (PD), which probably commences in the olfactory bulb and nuclei of IX and X, may represent accelerated normal aging or a disease specific process. The olfactory and motor disorders are associated in PD, so that smell loss should reflect the underlying disease course. Information on age‐associated decline can be obtained by single measurement from cross‐sectional analysis of patients and controls of different ages, because the observed between‐subject picture may reflect a similar within‐subject pattern. University of Pennsylvania Smell Identification Test (UPSIT) scores were examined for aging effects in 263 controls and 266 PD patients. Three models were applied that are (a) simple linear regression and (b) quadratic term in age: (i) assuming two parallel curves and (ii) allowing for two separate curves. Both groups declined with age. All three models were fitted successfully to the cross‐sectional data and none suggested that the lower mean UPSIT score in patients compared to controls was a premature ageing effect. The mean PD‐UPSIT score even at the age of 40, was lower than the control mean at the upper life‐span limit, implied that the decline in olfaction in PD is faster than simple aging. Extrapolation back in time suggested onset before birth, which is unlikely and implies that at some point there is a more rapid decline than observed in this sample. On the basis of olfactory measurement, our data are consistent with the proposal that PD starts as an acute event, followed by further disease progression more rapid than simple aging. © 2007 Movement Disorder Society
Strip and gap plasmon polariton optical resonators
Authors: Søndergaard T. , Bozhevolnyi S. I. 
Published: October 2007

AbstractA rectangular silver strip and two strips separated by a narrow gap are considered as optical resonators. A surface integral equation method is used to study theoretically their scattering cross section and local enhancement of the electric field relative to the incident wave. Peaks in the scattering spectra are shown to be related to the excitation of standing waves caused by forward and backward travelling slow plasmon polaritons (PPs) in the silver strip or in the gap between two strips. This is shown via analysis of the electric near‐field inside and outside the strips, and by showing that an increase of the length of strips equal to half the slow PP wavelength re‐ sults in a scattering resonance at app. the same wavelength. We study the broadening of resonances with strip thickness or gap size, respectively, for the two types of resonators. For field enhancement purposes we consider taking advantage of the fact that the electric field component of slow PPs along the axis of PP propagation is dominating inside the metal strips. Due to this fact and the electromagnetics boundary conditions forcing the surface normal electric field component to jump across the silver‐air interface a small (5 nm) gap introduced in one of the strips leads to a factor ∼25 enhancement of the field magnitude.
