Oral health in nursing home residents with different cognitive statuses
Authors: Chen Xi , Clark Jennifer J. J. , Naorungroj Supawadee 
Published: February 2012

Objective:  To compare oral health in nursing home (NH) residents with different cognitive statuses.Background:  Oral health is a significant issue for NH residents because of its relationships to quality of life, systemic health and well‐being. It is known that oral health is poor in NH residents. However, how oral health differs in NH residents with different cognitive statuses remains unclear.Materials and methods:  Nine hundred and two NH residents were retrospectively recruited from a community‐based geriatric dental clinic in Minnesota, USA. Comprehensive medical, dental, cognitive and functional assessments were completed for the participants. On the basis of medical history and cognitive status, participants were categorized into three groups: without cognitive impairment (non‐impaired group), with cognitive impairment but no dementia (impaired group) and with dementia (demented group). ANOVA, Chi‐square and Fisher’s exact tests were used to compare medical, dental and functional statuses between groups.Results:  Oral hygiene was poor in NH residents. Forty per cent of participants in the impaired group were edentulous, significantly higher than the edentulism rate in the demented group (29%, p = 0.01). More than 60% of the participants lost 16 or more teeth prior to examination. Depending on their cognitive status, 82–92% of the participants arrived with one or more caries or retained root. Dentate participants in the impaired and demented groups averaged about six caries or retained roots, significantly more than 4.7 caries or retained roots in the non‐impaired group (p = 0.01).Conclusion:  Oral health was poor but slightly different in NH residents with different cognitive and functional statuses.
Sex after Stroke: A Content Analysis of Printable Educational Materials Available Online
Authors: Hamam Natalie , McCluskey Annie , Robbins Spring Cooper 
Published: February 2012

Background Providing written educational materials to stroke survivors is a key recommendation in many international stroke guidelines. Yet, sexual concerns are generally overlooked in current stroke rehabilitation and the content of educational materials on sexual concerns has not been analyzed nor evaluated in published stroke research. Aim The aim of this study was to identify, describe, and analyze printable educational materials on sexual concerns that are available online and easily shared with stroke survivors. Method Google search engine was used to locate printable educational materials from the Internet using a search term strategy of 35 phrases that were piloted for accuracy. The content of eligible materials was analyzed using NVivo software to produce both enumerative and thematic data. Results Nine educational materials from reputable organizations were included with an average length of seven pages and 1445 words (total 61 pages, 13 000 words). The content of the materials was similar and covered three main content areas: problems experienced after stroke: 30% coverage suggested solutions: 32% coverage, and reassurance: 9% coverage. Content describing potential problems reflected published research, but solutions and reassurance were general, nonspecific, and often not supported by evidence. Conclusions Educational materials on sex after stroke may be helpful for health professionals, stroke survivors, and their partners, yet some messages appear to discourage recovery. Educators, health professionals, and organizations can use this analysis to evaluate their own educational resources and create resources that better address the sexual concerns of stroke survivors and their partners.

OBJECTIVE:  The study was aimed to assess the efficacy of sodium phosphate (NaP) tablets and polyethylene glycol (PEG) on colon cleansing.METHODS:  A prospective, randomized trial was conducted at the Graduate School of Medicine, University of Tokyo. Participants who were scheduled for colonoscopy were included and randomized into either the NaP or PEG group. An interim analysis was programmed into the study design when approximately 50% of the enrolments were completed. The primary outcome was the detection rate of polyps with a diameter ≤5 mm.RESULTS:  A total of 92 patients were included in the analysis, of whom 44 were in the NaP group and 48 in the PEG group. The quality of colonic preparation was similar in both groups. The NaP group showed a higher detection rate of polyps with a diameter ≤5 mm than the PEG group (38.6% vs 18.8%, P = 0.004). A multivariate analysis showed that NaP and the withdrawal time of the colonoscope were independent factors associated with the detection of polyps with a diameter ≤5 mm.CONCLUSIONS:  NaP is certainly not inferior to PEG. In fact, the results suggest that diminutive polyp detection using NaP might be superior to that using PEG.

OBJECTIVE:  This study was aimed to evaluate the prevalence of eosinophilic esophagitis (EoE) among patients with esophageal or upper gastrointestinal (UGI) symptoms.METHODS:  Patients with esophageal or UGI symptoms including dysphagia food impaction, acid regurgitation, heartburn, chest pain, epigastric pain, nausea and/or vomiting were prospectively collected. The enrolled patients responded to a symptomatic questionnaire and underwent an esophagogastroduodenoscopy and esophageal biopsies. Supportive endoscopic findings of EoE (ring‐like appearance, liner furrows, whitish papules, shearing or friability) were recorded. EoE was diagnosed if patients had chronic UGI or esophageal symptoms, the esophageal biopsy showed ≥15 eosinophils/high‐power field and were unresponsive to 2–3 weeks of proton pump inhibitors.RESULTS:  A total of 122 patients were enrolled and supportive endoscopic findings were found in 31 (25.4%) patients [whitish papules: 19 (15.6%), ring‐like appearance: 8 (6.6%), linear furrows: 5 (4.1%)]. One patient had a simultaneous ring‐like appearance and linear furrows. EoE was diagnosed in 8 (6.6%) patients and supportive endoscopic findings and past history of gastroesophageal reflux disease, allergic rhinitis and atopic dermatitis were more common in EoE positive than EoE negative patients. The diagnostic yield of endoscopic findings was 40.0% (2/5) in linear furrows, 25.0% (2/8) in ring‐like appearance and 15.8% (3/19) in whitish papules.CONCLUSION:  Prevalence of EoE among patients with esophageal or UGI symptoms was 6.6%. Linear furrows and ring‐like appearance had a relatively high diagnostic value.
Motzki’s Forger: The Corpus of the Follower ʿAṭāʾ in Two Early 3rd/9th-Century Ḥadīth Compendia
Authors: Gledhill P.J. 
Published: February 2012

AbstractTwenty years ago, Harald Motzki argued that preserved in the Muṣannaf of the 3rd/9thcentury Yemeni scholar ʿAbd al-Razzāq al-Ṣanʿānī are literary materials upon which we may rely to provide us with facts concerning the 1st/7th century. In particular, he pronounced (presumptively) authentic the body of ḥadīth ascribed in that work to the Meccan Follower ʿAṭāʾ in the transmission of his student Ibn Jurayj. Analysis of the corpus attributed to the same man in the Muṣannaf of a near-contemporary, the Iraqi jurist Ibn Abī Shayba, reveals that the claim to its authenticity cannot be sustained, at least in the sense Motzki intended. I show, moreover, how the evidence precludes the main interpretative principle that governed his analysis from being upheld without contradiction. Arguing that ḥadīth specialists have often reasoned from a false dichotomy (faithful transmission versus outright fabrication), I propose that future enquiry reckon more fully with the concept of fluid transmission.
English Secular Clergy in the Early Dominican Schools: Evidence from Three Manuscripts
Authors: Reeves Andrew 
Published: February 2012

AbstractAs part of their mission to preach faith and morals, the medieval Dominicans often served as allies of parochial clergy and the episcopate. Scholars such as M. Michèle Mulchahey have shown that on the Continent, the Order of Preachers often helped to educate parish priests. We have evidence that thirteenth- and fourteenth-century Dominicans were allowing parochial clergy to attend their schools in England as well. Much of this evidence is codicological. Two English codices of William Peraldus's sermons provide evidence of a provenance relating to a parish church: London Gray's Inn 20, a collection of his sermons on the Gospels, was owned by a parish priest, and Cambridge Peterhouse 211, a manuscript of his sermons on the Epistles, contains an act issued by the rector of a parish church. Another manuscript of Peraldus's sermons contains synodal statutes. As the Order of Preachers was outside of the diocesan chain of command, these statutes point to the use of these sermons by those who were subject to the episcopate.
Since the Dominicans were normally forbidden from sharing their model sermon literature with secular clergy, these codices suggest a program on the part of the English province of the Order of Preachers to make sure that diocesan clergy could attend Dominican schools in order to gain the skills necessary to preach the basic doctrines and morals of the Christian faith to England's laity.
Nomenclature report on rice WRKY's - Conflict regarding gene names and its solution
Authors:   Rice WRKY Working Group
Published: February 2012

Abstract

Background
Since whole genome sequences of rice were made publically accessible, the number of articles onnew rice genes has increased remarkably. The Committee on Gene Symbolization, Nomenclature and Linkage(CGSNL) of the Rice Genetics Cooperative published the gene nomenclature system for rice and encouragedresearchers to follow the rules before publishing their results. The CGSNL provides an on-line registration systemfor newly identified rice genes to prevent conflicts and/or duplication of gene name in journal articles.

Findings
Recently, the CGSNL surveyed genes in the rice WRKY family in published journal articles and foundseveral duplicated gene names.

Conclusions
To discuss and resolve inconsistencies in WRKY gene nomenclature, the rice WRKY working groupwas established and redefined the nomenclature. This report announces the conclusion.
Low-temperature Electrochemical Performance of LiFePO4/C Cathode with 3D Conducting Networks
Authors: Zheng Jun-chao , Zhang Bao , Zhang Ming , Wu Ling 
Published: February 2012

Abstract
The low-temperature electrochemical performance of LiFePO4/C cathode with 3D conducting networks is reported. XRD results show the sample is olivine-type structure. SEM and TEM images indicate that the particles consist of nanocrystalline LiFePO4 and are coated by nanocarbon webs and form conducting 3D networks. The 3D networks contained two effectively mixed conducting networks, one on the nanoscale and the other on the microscale. It is useful to shorten the distance of Li+ diffusion and e− transport and to improve the electrochemical performance. The LiFePO4/C cathodes show excellent capacity retention and cycling performance at −20 °C for lithium-ion batteries.

Published: February 2012

Abstract
We investigated the nonlinear optical (NLO) properties of two newly synthesized conjugated polymers P1 and P2 carrying 1,3,4-oxadiazole, 3,4-dibenzyloxythiophene, and 3,4-dialkoxythiophene moieties along the main chain, as potential NLO active materials. Their structures have been well characterized. The nonlinear measurements were performed by Z-scan using 532 nm, 7 ns laser pulses. Calculated values of figure of merit and β follow the criteria for good NLO materials. These results suggest that polymers are promising materials for applications in photonics.

Published: February 2012

Abstract
A new polymer prepared by polymerization of 3,5-bis(hydroxymethyl)phenylacetylene having a chiral menthyl group via a very long and rigid spacer by an achiral rhodium complex with triethylamine as an initiator showed strong CD absorptions assigned to the main chain in spite of the long distance (23 Å) between the chiral group and the polymerizing group in the monomer. This distance is the longest to the best of our knowledge. In addition, switching between the two chiralities of the resulting polymer was realized in the CD spectrum.

Published: February 2012

Abstract
We investigated the formation of a high-viscosity wormlike-micelle solution consisting of a mixed aqueous solution containing the cationic surfactant cetyltrimethylammonium bromide (CTAB) and sodium cinnamate (NaCin) and control of the solution viscosity by photoisomerization of the NaCin. The aqueous CTAB/NaCin solution exhibited higher zero-shear viscosity than a classic wormlike micelle-forming system CTAB/sodium salicylate of the same concentration. UV irradiation of the aqueous CTAB/NaCin wormlike-micelle solution resulted in a remarkable decrease in its viscosity, from 6.6 × 10 to 2.1 × 10−3 Pa s.
Synthesis of Polyfluorene Block Copolymers and Effect of Side Chain Group on Electroluminescent Device Performance
Authors: Tan Ying , Tsuchiya Kousuke , Ogino Kenji 
Published: February 2012

Abstract
Blue-light-emitting block copolymers based on polyfluorene (PF) and poly(triphenylamine) (PTPA) were synthesized for polymeric electroluminescent (EL) materials. PF with diphenylamine terminals were prepared by the Suzuki coupling polymerization, and converted to PTPA-block-PF-block-PTPA triblock copolymers by C–N coupling polymerization. The block copolymers with different substituents on PTPA segment, hydrophilic trioxyethylene (TEO) group (PF–PTPA–TEO) or hydrophobic n-butyl group (PF–PTPA–C4), were prepared in order to investigate their effect on device performance. The block copolymers showed relatively high HOMO levels compared with PF. EL devices based on the block copolymers showed higher luminance and current efficiency than that of PF homopolymer because of the improvement of hole injection by the introduction of PTPA segment. Modification by TEO group provided higher device performance than n-butyl group, indicating that PTPA segment segregated at the interface with PEDOT:PSS by the hydrogen-bonding interaction.
Determination of Tinuvin 292 in Acrylic Resins by Reversed-phase High-performance Liquid Chromatography–Electrospray Ionization–Ion Trap Mass Spectrometry
Authors: Park Insook , Yoon Kyung-Hwan , Namgoong Hyun 
Published: February 2012

Abstract
Due to recent reports on toxicity of hindered-amine light stabilizers (HALS) in polymer materials, demand for the regulation of the dosage of HALS is increasing. Therefore development of a quantitation method for low concentration of HALS is required either for toxicity study of HALS in water or saliva extracts from polymeric materials or for accurate determination of reduced amounts of HALS in polymeric materials. Here we present a novel quantitation method for Tinuvin 292, a worldwide used HALS, in acrylic resins using high-performance liquid chromatography–electrospray ionization–ion trap mass spectrometry at a broad concentration ranging from 10 ppb to 50 ppm. Collision-induced dissociation was performed using helium gas, and the multiple reaction monitoring parameters were optimized for detection of parent/daughter ions of Tinuvin 292. Sample preparation employed a very simple extraction of Tinuvin 292 from acrylic resins with considerable recovery. The method was successfully applied to quantitate Tinuvin 292 in various acrylic polymers.

Abstract
The introduction of the cationic luminescent iridium(III) and ruthenium(II) complexes into negatively charged poly(l-glutamic acid) (P(Glu)) as a polymeric scaffold, wherein control of the conformational change of P(Glu) was achieved, was allowed to induce the tuning of the emission properties and energy transfer in an aqueous media.
The natural history of asymptomatic lumbar canal stenosis in patients undergoing surgery for cervical myelopathy

Published: February 2012

We retrospectively examined the prevalence and natural history of asymptomatic lumbar canal stenosis in patients treated surgically for cervical compressive myelopathy in order to assess the influence of latent lumbar canal stenosis on the recovery after surgery. Of 214 patients who had undergone cervical laminoplasty for cervical myelopathy, we identified 69 (32%) with myelographically documented lumbar canal stenosis. Of these, 28 (13%) patients with symptomatic lumbar canal stenosis underwent simultaneous cervical and lumbar decompression. Of the remaining 41 (19%) patients with asymptomatic lumbar canal stenosis who underwent only cervical surgery, 39 were followed up for ≥ 1 year (mean 4.9 years (1 to 12)) and were included in the analysis (study group). Patients without myelographic evidence of lumbar canal stenosis, who had been followed up for ≥ 1 year after the cervical surgery, served as controls (135 patients; mean follow-up period 6.5 years (1 to 17)). Among the 39 patients with asymptomatic lumbar canal stenosis, seven had lumbar-related leg symptoms after the cervical surgery. Kaplan–Meier analysis showed that 89.6% (95% confidence interval (CI) 75.3 to 96.0) and 76.7% (95% CI 53.7 to 90.3) of the patients with asymptomatic lumbar canal stenosis were free from leg symptoms for three and five years, respectively. There were no significant differences between the study and control groups in the recovery rate measured by the Japanese Orthopaedic Association score or improvement in the Nurick score at one year after surgery or at the final follow-up. These results suggest that latent lumbar canal stenosis does not influence recovery following surgery for cervical myelopathy; moreover, prophylactic lumbar decompression does not appear to be warranted as a routine procedure for coexistent asymptomatic lumbar canal stenosis in patients with cervical myelopathy, when planning cervical surgery.

Published: February 2012

Most patients (95%) with fibular hemimelia have an absent anterior cruciate ligament (ACL). The purpose of this study was to assess the long-term outcome of such patients with respect to pain and knee function. We performed a retrospective review of patients with fibular hemimelia and associated ACL deficiency previously treated at our institution. Of a possible 66 patients, 23 were sent the Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) questionnaire and Lysholm knee score to complete. In all, 11 patients completed the MODEMS and nine completed the Lysholm score questionnaire. Their mean age was 37 years (27 to 57) at review. Five patients had undergone an ipsilateral Symes amputation. There was no significant difference in any subsections of the Short-Form 36 scores of our patients compared with age-matched controls. The mean Lysholm knee score was 90.2 (82 to 100). A slight limp was reported in six patients. No patients had episodes of locking of the knee or required a supportive device for walking. Four had occasional instability with sporting activities.These results suggest that patients with fibular hemimelia and ACL deficiency can live active lives with a similar health status to age-matched controls.

Role of an ionic liquid, 1-butyl-3-methylimidazolium 2-(2-methoxyethoxy)ethyl sulfate in extraction studies of gadolinium oxide
Authors: Sen Kamalika , Wolterbeek H. Th. 
Published: February 2012

Abstract
The room temperature ionic liquid (RTIL), 1-butyl-3-methylimidazolium 2-(2-methoxyethoxy)ethyl sulfate was studied for its extraction behavior for 159Gd in an environmentally benign liquid–liquid extraction system. The gadolinium oxide when dissolved in nitric acid and extracted in an RTIL/dextran biphasic system, was found to get completely extracted in the IL phase. The otherwise difficult to dissolve gadolinium oxide was found to have some solubility in the IL studied. Biphasic systems consisting of IL/dextran and certain IL/salt were studied for the extraction behavior of Gd2O3 dissolved in the above RTIL. A similar experiment was also done with acid-dissolved gadolinium oxide for comparison.
