Published: February 2009

Objective:  To investigate how dental implants impact on the oral health quality of life of people with Parkinson’s disease (PD).Background:  PD is a progressive neurological disorder that can result in a number of oral health care challenges, including denture difficulties. Lack of evidence related to use of implants in PD prompted this study to investigate their use in this group of people.Materials and methods:  Nine people with PD were provided with either fixed or removable prostheses using Astra‐Tech implants. Participants completed the socio‐dental questionnaire, ‘The Dental Impact on Daily Living Assessment’ (DIDL) prior to implant surgery, and at 3 and 12 months after provision of the final prosthesis. DIDL comprises two components – the Oral Health Quality of Life Inventory (OH‐QoL) and the Self‐Reported Assessment of Oral Health and Functional Status (SROH).Results:  Nine people (with an age range of 54–77 years) had implants placed. The implant success rate was 85 and 81% in the maxilla and mandible, respectively. The OH‐QoL and SROH results (analysed using the one‐way analysis of variance and pairwise multiple comparisons) demonstrated a significant improvement in the domains of eating and satisfaction with the prosthesis after 3 months, which was maintained at the twelve month review. The OH‐QoL indicated a gradual improvement in oral well‐being over the 12‐month period.Conclusion:  The oral health quality of life of people with PD was improved by the use of dental implants, indicating this as a viable treatment option.
Robert Browning's Compounds
Authors: Wilson Ross 
Published: February 2009

AbstractThis article is part of a cluster that draws material from the recent conference Metre Matters: New Approaches to Prosody, 1780–1914. It comprises an introduction by Jason David Hall and six articles presented at the conference, whose aim was to address renewed scholarly interest in versification and form across the long nineteenth century, as well as some of the methodologies underpinning it. The papers included in the cluster look both to the minutiae of Romantic and Victorian metres and to their cultural intertexts. The conference, hosted by the University of Exeter's Centre for Victorian Studies, was held 3–5 July 2008.The cluster is made up of the following articles: Jason David Hall, ‘Metre, History, Context: Introduction to the Metre Matters Cluster’.Emma Mason and Rhian Williams, ‘Reciprocal Scansion in Wordsworth's “There Was a Boy” ’.Ross Wilson, ‘Robert Browning's Compounds’.Margaret A. Loose, ‘The Internationalism of Ernest Jones's Dialectical Prosody’.Nancy Jiwon Cho, ‘Gender and Authority in British Women Hymn‐Writers’ Use of Metre, 1760–1900’.Ashley Miller, ‘Involuntary Metrics and the Physiology of Memory’.Summer Star, ‘ “For the Ins?ape's Sake”: Sounding the Self in the Metres of Gerard Manley Hopki&#x006e;̇s’.***This article is a study of the use of compound words in Robert Browning's poetry. It explores the use of compounds in Sordello, The Ring and the Book and The Agamemnon of Aeschylus in particular. Although it addresses the semantic aspects of compound words, it especially focuses on their metrical aspects and thus makes a contribution to our current understanding of Browning's versification. I claim that the metrical features of compound words are central to the formation of meaning in Browning's verse. In order to conduct this investigation, I draw on work by a number of literary critics, metrists and linguists, including Derek Attridge, Noam Chomsky and Morris Halle.
The Internationalism of Ernest Jones's Dialectical Prosody

AbstractThis article is part of a cluster that draws material from the recent conference Metre Matters: New Approaches to Prosody, 1780–1914. It comprises an introduction by Jason David Hall and six articles presented at the conference, whose aim was to address renewed scholarly interest in versification and form across the long nineteenth century, as well as some of the methodologies underpinning it.

This essay examines some prosodic tensions in ‘A Song for May’ (1847), an unlikely example of his internationalism because its topic has nothing to do with it. However, the formal features of the poem – from its stanzaic organization to its metrical choices, its focus on the plight of individuals to its communal nature as a Chartist song – call for a dialectical negotiation of its public and private qualities that maps onto Jones's nuanced treatment of personal and collective identities in his internationalist writing. His emphasis on the individual's ability to define itself would seem to contradict his broader intention to foster a mass, class‐based identity that seeks social justice through collective action. But it is precisely that power which permits one to choose one's loyalties and national identity, choices that might not coincide with the accidents of birth and ancestry, and which thus open the way for a border‐crossing solidarity. A dialectical prosody illuminates Jones's poetics and could also cast light on the junction of poetry and politics in the writing of authors both within and beyond Chartism.

AbstractBois noir (BN) is an insect‐transmitted grapevine yellows disease caused by phytoplasmas belonging to the stolbur subgroup 16SrXII‐A. In Italy, increasing prevalence of stolbur phytoplasma strains in vineyards suggests progressive spread of the disease and potential for heavy impacts on the wine industry. In this study, we investigated the genetic diversity of stolbur phytoplasma strains in BN phytoplasma populations. Nucleotide sequences of16S rRNAgenes from stolbur phytoplasma strains affecting vineyards in the Lombardy region of Italy and stolbur phytoplasma 16S rDNA sequences retrieved from GenBank were subjected to virtual restriction fragment length polymorphism analysis. Calculation of virtual restriction similarity coefficients revealed the presence of new subgroups in group 16SrXII (stolbur phytoplasma group). Representative strains of confirmed new subgroups 16SrXII‐F (XII‐F) and XII‐G and tentative new subgroups XII‐A1 through XII‐A19, XII‐H, XII‐I, and XII‐J as well as known subgroup XII‐A were from grapevines; strains representing three additional tentative new subgroups (XII‐K, XII‐L and XII‐M) were from other plant hosts. Nucleotide sequence alignments identified no less than nine genetically distinct 16S rDNA single nucleotide polymorphism lineages from grapevine, indicating a high degree of genetic heterogeneity within BN phytoplasma populations. The findings open new opportunities for in‐depth studies of the distribution of grapevine‐associated 16SrXII phytoplasma strains in weeds, insect vector populations and grapevines from vineyards located in different geographic areas.

AbstractWe carried out a quantitative detection of Candidatus Liberibacter asiaticus, the bacterium associated with the disease of huanglongbing, in the vector psyllid Diaphorina citri by using a TaqMan real‐time PCR assay. The concentration of the bacterium was monitored at 5‐day intervals for a period of 20 days after psyllids were exposed as fifth instar nymphs or adults to a Ca. L. asiaticus‐infected plant for an acquisition access period of 24 h. When adults fed on Ca. L. asiaticus‐infected plant, the concentration of the bacterium did not increase significantly and the pathogen was not transmitted to any citrus seedlings. In contrast, when psyllids fed on infected plant as nymphs, the concentration of the pathogen significantly increased by 25‐, 360‐ and 130‐fold from the initial acquisition day to 10, 15 and 20 days, respectively. Additionally, the pathogen was successfully transmitted to 67% of citrus seedlings by emerging adults. Our data suggested that multiplication of the bacterium into the psyllids is essential for an efficient transmission and show that it is difficult for adults to transmit the pathogen unless they acquire it as nymphs.
Modified Gravity and the origin of inertia
Authors: Moffat J. W. , Toth V. T. 
Published: February 2009

Abstract
Modified gravity theory is known to violate Birkhoff's theorem. We explore a key consequence of this violation, the effect of distant matter in the Universe on the motion of test particles. We find that when a particle is accelerated, a force is experienced that is proportional to the particle's mass and acceleration and acts in the direction opposite to that of the acceleration. We identify this force with inertia. At very low accelerations, our inertial law deviates slightly from that of Newton, yielding a testable prediction that may be verified with relatively simple experiments. Our conclusions apply to all gravity theories that reduce to a Yukawa-like force in the weak-field approximation.
Isolation and characterization of 11 microsatellite loci from the black fly, Simulium negativum (Diptera: Simuliidae)

Published: February 2009

AbstractEleven polymorphic microsatellite loci were isolated and developed from the black fly, Simulium negativum, a member of the Simulium arcticum sibling species complex. The observed heterozygosity of the 11 loci ranged from 0.03 to 0.83. The number of alleles per locus ranged from 8 to 19. Significant linkage disequilibria were encountered only for the primer pairs BF7‐1 with BF7‐5 and BF6‐32 with BF7‐16. Presumably, these microsatellite loci can be used to study genetic structure within the entire S. arcticum complex.

Objective:  With the development of diagnostic techniques and in‐depth understanding of lateral curvature of the spine (scoliosis), it is possible to differentiate idiopathic scoliosis from other forms with various known etiologies. The present study was to analyze data collected at the authors' center according to the current etiological spectrum and classification of scoliosis.Methods:  One thousand, two hundred and eighty‐nine consecutive patients with different forms of structural scoliosis were reviewed. The average age at first visit was 18 years, ranging from 4 months to 79 years. Corrective surgery was performed on patients aged from 9 to 28 years; their clinical data were retrieved for independent statistical analyses, and further compared with those obtained from the whole group.Results:  The prevalence of non‐idiopathic scoliosis was 25.3% in the whole series, but it increased to 34% in the surgical group aged from 9 to 28 years. Thirty‐nine percent of patients with congenital scoliosis presented at least one developmental spinal cord malformation.Conclusion:  The current study has shown that the etiological distribution of scoliosis has changed a lot from what was true decades ago. Developmental malformation related to scoliosis is one of the risk factors for neurological complications during corrective surgery, so it is important to make an accurate diagnosis and take appropriate prophylactic measures to avoid relative neurological complications.

Objective:  To analyze the clinical results of simultaneously combined anterior and posterior surgery for severe thoracolumbar fracture dislocations, and to clarify the surgical indications for these high‐energy injuries.Methods:  Thirty‐four patients with severe thoracolumbar fracture dislocations were managed with simultaneously combined anterior and posterior surgery. The injured segments included the following: T11 (2 patients), T12 (5), L1 (1), L2 (8), L3 (5), L4 (2) and L4 and L5 (1). When classified according to the Magerl Classification, the breakdown was as follows: 12 A3 injuries, 2 B1, 2 B2, 12 C1 injuries, 4 C2, and 2 C3. Clinical data, including operative procedures, neurological changes, postoperative CT scans and sequential radiographs, was collected and analyzed. Thirty‐two patients were followed up for an average of 13 months (range, 6–60).Results:  Operative time ranged from 180 to 320 min with a mean of 230 min. Intraoperative blood loss ranged from 900 to 2400 ml with a mean of 1200 ml. According to the classification of the American Spinal Injury Association (ASIA), neurological status improved at least 1 grade in all of the 24 patients who had an incomplete paralysis preoperatively. Satisfactory decompressions, reductions and reconstructions were obtained and well maintained in all patients at all intervals of follow‐up.Conclusion:  For severe thoracolumbar fracture dislocations that cannot be effectively treated with either an anterior or posterior approach alone, simultaneously combined anterior and posterior surgery is a reliable method that can achieve a sufficient decompression, reduction and reconstruction.

Objective:  To evaluate the results of treatment of osteonecrosis of the femoral head by structural augmentation through a routine core decompression procedure combined with insertion of cannulated bone screws incorporating autogenous bone graft and biomaterial containing decalcified bone matrix.Methods:  From February 2002 to February 2005, 31 patients (33 hips) with femoral head necrosis were treated in our hospital using insertion of cannulated bone screws incorporating autogenous bone graft. There were 18 men and 13 women with an average age of 37 years (range, 27–49). The Steinberg classification was stage I for 20 hips (61%) and stage II for 13 hips (39%). Clinical and radiographic evaluations were performed on all patients. The patient's satisfaction was also assessed.Results:  All 31 patients (33 hips) were retrospectively studied after a mean follow‐up of 38 months (range, 18–48). The average Harris hip score was 76 before surgery and 91 at the final follow‐up. All patients stated that they were satisfied and had significantly reduced pain. According to the Harris hip score system, 21 cases were excellent, 8 good and 2 fair. No complications, such as wound infection, subtrochanteric fracture, neuropathy and deep vein thrombosis, were found.Conclusion:  Structural augmentation using the insertion of cannulated bone screws incorporating autogenous bone graft is an effective option for Steinberg I–II stages of femoral head necrosis. Further study is needed to confirm mid‐ and long‐term results.

Published: February 2009

Objective:  To investigate whether: (i) rs12885713 (−16C > T) and rs5871 polymorphisms in the Calmodulin1 (CALM1) gene are predisposing factors for adolescent idiopathic scoliosis (AIS); and (ii) different single nucleotide polymorphisms (SNP) correlate with different subtypes of AIS.Methods:  A total of 100 AIS patients with Cobb angle above 30° were recruited for this study together with 100 healthy controls. Curve pattern, Cobb angle, and Risser sign were recorded. Two polymorphic loci, rs12885713 (−16C > T) and rs5871 loci, of the CALM1 gene were analyzed. All patients were grouped according to the Peking Union Medical College (PUMC) classification, the apical location of the major curve, and the Cobb angle.Results:  There was a statistically significant difference in the distribution of rs12885713 site polymorphism (P = 0.034) between PUMC type II (double curve) patients and controls, in the distribution of rs12885713 site polymorphism (P = 0.009) between lumbar curve cases and controls and in the distribution of rs5871 site polymorphism (P = 0.035) between thoracic curve patients and controls.Conclusion:  Different subtypes of AIS might be related to different SNP. The susceptibility of PUMC type II (double curve) AIS and lumbar curve might be related to CALM1 rs12885713 site polymorphism, while rs5871 site polymorphism might be a risk indicator for thoracic curve cases.

Published: February 2009

Objective:  To compare the results of lateral versus medial‐sided augmentation techniques in single‐bundle posterior cruciate ligament (PCL) reconstruction with remnant preservation.Methods:  Forty‐two cases of isolated chronic PCL ruptures were reconstructed in a single‐bundle manner with remnant preservation. The patients were randomly separated into two groups: in the medial‐sided augmentation (MSA) group the graft passed through the medial side of the remnant and in the lateral‐sided augmentation (LSA) group it passed through the lateral side.Results:  Nineteen patients in the MSA group and 17 in the LSA group were followed up for a minimum of 2 years. At the final follow‐up, the average side‐to‐side differences in posterior laxity were 1.6 ± 1.2 mm and 1.5 ± 1.3 mm respectively in the MSA and LSA groups. According to the International Knee Documentation Committee (IKDC) scale, patient numbers graded as normal, nearly normal and abnormal were 14 (73.7%), 4 (21.1%), and 1 (5.3%) in the MSA group, and 13 (76.5%), 3 (17.6%), and 1 (5.9%) in the LSA group. The IKDC subjective scores were 93.1 ± 3.8 and 92.6 ± 4.1, the Lysholm scores were 95.0 ± 4.6 and 93.7 ± 4.2, and the Tegner scores were 5.4 ± 0.9 and 5.6 ± 0.7 respectively in the MSA and LSA groups. Statistical analysis showed no significant differences between the MSA and the LSA group regarding all subjective and objective results.Conclusion:  In single‐bundle PCL reconstruction with remnant preservation, similar subjective and objective results can be obtained with MSA and LSA techniques.

Aim:  We estimated viral dynamics after serum hepatitis C virus (HCV) RNA became negative and assessed the relation between the estimated viral load at the end of treatment (EVE) index and the response to the combination therapy with peginterferon α‐2b plus ribavirin.Methods:  Patients with chronic HCV, genotype 1b, and a high viral load were treated with this combination therapy for 48 weeks, and serum HCV RNA was measured frequently during the treatment period. In the patients showing an end‐of‐treatment response (ETR), the viral load profile from the start of treatment until serum HCV RNA became negative was expressed by an approximate curve. Then the EVE index was calculated by using the expression obtained from the curve, and differences between the sustained virologic response (SVR) and relapse groups were investigated. Results: The SVR rate increased as the EVE index became lower, and the EVE index was significantly lower in the SVR group than in the relapse group. The SVR rate was higher for those in whom the EVE index was below the cut‐off point.Conclusion:  Prediction of SVR and relapse from the EVE index is more useful than prediction from viral dynamics at the time when HCV RNA becomes negative or when HCV RNA shows a decrease of 2‐log or more.

Aim:  The average age of Japanese patients with drug‐induced liver injury (DILI) is expected to rise as the population ages. The aim of this study was to evaluate the clinical characteristics of DILI in elderly Japanese subjects.Methods:  A total of 142 hospitalized patients with DILI were divided into three groups by age (Group A, < 65 years; Group B, 65–74 years; Group C, ≥ 75 years). Patients were examined retrospectively with regard to the number of concomitant drugs, duration of drug intake until onset of DILI, clinical types of DILI, treatment, prognosis, and scores on the diagnostic scale described by Digestive Disease Week, Japan 2004.Results:  Patients in Group C used more concomitant drugs (P = 0.0019) compared with patients in Group A. The elderly had a higher frequency of unclear duration of drug intake (P = 0.0020), were more likely to experience cholestatic type DILI (P = 0.033), and underwent more intensive treatment for DILI (P = 0.011). There were fewer cases diagnosed as a “high possibility” of DILI in Group C compared with Group A (P = 0.030) and Group B (P = 0.013). In cases diagnosed as “possible” or “low possibility” of DILI, unclear duration of drug intake was more frequently observed in the elderly (P = 0.0027).Conclusion:  Elderly patients with DILI show different clinical features than younger patients with DILI. These features should be taken into account in the diagnosis and treatment of DILI in the elderly.
