Background
In Japan, the number of older adults requiring long-term care insurance (LTCI) is increasing and the cost is becoming a social problem. In these fields, the role of geriatric rehabilitation includes maintaining the physical function and LTCI certification levels. The prevalence of sarcopenia is high among older adults requiring LTCI certification, and there are many opportunities to assess the handgrip strength, walking speed, and muscle mass. This study aimed to identify sarcopenia-related assessments sensitive to transitions in LTCI certification levels and determine cut-off values to predict them.

Methods
This prospective cohort study analyzed 98 daycare users (mean age ± standard error: 78.5 ± 0.8 years) between March 2019 and 2023. The participants received LTCI certification before the study, and their levels were renewed between baseline and follow-up (six months later). The measurements included handgrip strength, usual walking speed, body composition, and SARC-F score. Participants were classified into maintenance, deterioration, and improvement groups according to the changes in their LTCI certification levels. We identified factors contributing to the deterioration of LTCI certification levels using baseline and before and after comparisons, multivariate analyses, and receiver operating characteristic analyses.

Results
No significant differences were observed in the baseline data among the groups. Only the deterioration group showed significant changes in the usual walking speed (baseline: 0.64 ± 0.25 m/s, follow-up: 0.53 ± 0.21 m/s, P = 0.008) and body fat percentage (baseline: 29.2 ± 9.9%, follow-up: 27.7 ± 10.3%, P = 0.047). Binomial logistic regression showed that changes in usual walking speed (P = 0.042) and body fat percentage (P = 0.011) were significantly associated with the deterioration of LTCI certification levels, even after adjustment. The cutoff values of change to discriminate the deterioration of LTCI certification levels were −0.14 m/s at the usual walking speed (P = 0.047) and −1.0% for body fat percentage (P = 0.029).

Conclusions
Decreases in usual walking speed and body fat percentage may predict worse certification levels in older adults requiring LTCI.

A study was conducted to investigate the “Evaluation of varying levels of Nano urea, FYM, and rhizobium on soil properties and yield characteristics of green gram (Vigna radiata. L) var. PDM 139” at the research farm of soil science and agricultural chemistry. The experiment followed a randomized block design (RBD) with three replications. Treatment T9 (NU at 100% + RZ at 100% + FYM at 100%) showed a slight decrease in pH (6.96 PH), bulk density (1.27 mg m-3), particle density (2.46 mg m-3), there was a significant increase in pore space (48.90%), water holding capacity (46.51%), EC (0.20 ds m-3), organic carbon (0.58%), available nitrogen (320 kg ha-1), phosphorus (21.4 kg ha-1), potassium (195.12 kg ha-1), and plant growth. Among all the treatment joint use of T9 (NU at 100% + RZ at 100% + FYM at 100%) showed the most significant impact on green gram growth through healthy soil.

AbstractMolecular switches play a central role for the development of molecular electronics. In this work it is demonstrated that the reproducibility and robustness of a single‐molecule dihydroazulene (DHA)/vinylheptafulvene (VHF) switch can be remarkably enhanced if the switching kernel is weakly coupled to electrodes so that the electron transport goes by sequential tunneling. To assure weak coupling, the DHA switching kernel is modified by incorporating p‐MeSC6H4 end‐groups. Molecules are prepared by Suzuki cross‐couplings on suitable halogenated derivatives of DHA. The synthesis presents an expansion of our previously reported bromination–elimination–cross‐coupling protocol for functionalization of the DHA core. For all new derivatives the kinetics of DHA/VHF transition has been thoroughly studied in solution. The kinetics reveals the effect of sulfur end‐groups on the thermal ring‐closure of VHF. One derivative, incorporating a p‐MeSC6H4 anchoring group in one end, has been placed in a silver nanogap. Conductance measurements justify that transport through both DHA (high resistivity) and VHF (low resistivity) forms goes by sequential tunneling. The switching is fairly reversible and reenterable; after more than 20 “ON‐OFF” switchings, both DHA and VHF forms are still recognizable, albeit noticeably different from the original states.
Fabrication of Chemical Gradient Using Space Limited Plasma Oxidation and its Application for Droplet Motion
Authors: Han Xiaojun , Wang Lei , Wang Xuejing 
Published: June 2012

AbstractA novel, simple, versatile, rapid, and inexpensive method, “space limited oxygen plasma oxidation” is developed to fabricate chemical gradient on both alkylsilane and alkanethiol self‐assembled monolayers (SAMs) surface. XPS data confirm that the methyl groups of alkane SAMs are converted into oxidized carbon functional groups. The influences of RF power, O2 flow rate, and the “wedge” shape on gradient formation are investigated in details. Gradient surfaces with various scales and depths are formed by simply changing the ‘wedge’ shape or plasma generation parameters. The application of formed chemical gradient on droplet motion has been demonstrated as well.
Mo‐Si‐B Alloys for Ultrahigh‐Temperature Structural Applications
Authors: Lemberg J. A. , Ritchie R. O. 
Published: June 2012

AbstractA continuing quest in science is the development of materials capable of operating structurally at ever‐increasing temperatures. Indeed, the development of gas‐turbine engines for aircraft/aerospace, which has had a seminal impact on our ability to travel, has been controlled by the availability of materials capable of withstanding the higher‐temperature hostile environments encountered in these engines. Nickel‐base superalloys, particularly as single crystals, represent a crowning achievement here as they can operate in the combustors at ∼1100 °C, with hot spots of ∼1200 °C. As this represents ∼90% of their melting temperature, if higher‐temperature engines are ever to be a reality, alternative materials must be utilized. One such class of materials is Mo‐Si‐B alloys; they have higher density but could operate several hundred degrees hotter. Here we describe the processing and structure versus mechanical properties of Mo‐Si‐B alloys and further document ways to optimize their nano/microstructures to achieve an appropriate balance of properties to realistically compete with Ni‐alloys for elevated‐temperature structural applications.

Published: June 2012

AbstractBackgroundRecent studies suggest that occupational exposures such as noise and organic solvents may affect blood pressure. The aim of this study was to investigate interaction of noise and mixed organic solvents on blood pressure.MethodsFour hundred seventy‐one workers of a car manufacturing plant were divided into four groups: group one or G1 workers exposed to noise and mixed organic solvents in the permitted limit or control group, G3 exposed to noise only, G2 exposed to solvents only, and G4 workers exposed to noise and mixed organic solvents at higher than the permitted limit or co‐exposure group. Biological interaction of two variables on hypertension was calculated using the synergistic index.ResultsThe workers of co‐exposure group (G4), noise only group (G3), and solvents only group (G2) had significantly higher mean values of SBP and DBP than workers of control group (G1) or office workers (P < 0.05). Also logistic regression analysis showed a significant association between hypertension and exposure to noise and mixture of organic solvents. Odds ratio for hypertension in the co‐exposure group and the noise only and solvents only exposed groups was 14.22, 9.43, and 4.38, respectively, compared to control group. In this study, the estimated synergism index was 1.11.ConclusionsOur results indicate that exposure to noise or a mixture of organic solvents may be associated with the prevalence of hypertension in car manufacturing company workers and co‐exposure to noise and a mixture of solvents has an additive effect in this regard. Therefore appropriate preventive programs in these workers recommended. Am. J. Ind. Med. 56:243–251, 2013. © 2011 Wiley Periodicals, Inc.
Silicone rubber/polyvinylpyrrolidone microfibers produced by coaxial electrospinning
Authors: Lu Shengguo , Duan Xujia , Han Yuwang , Huang He 
Published: June 2012

AbstractCore‐shell structured silicone microfibers were prepared by coaxial electrospinning using polyvinylpyrrolidone (PVP) as the shell and silicone rubber (SR) as the core. The electrospinnability of SR at three time windows was evaluated and the electrospinning process was optimized accordingly. A positive correlation was found between the fibrous morphology and the SR/PVP speed ratios. As the speed ratio increased, the composite fiber showed larger diameter and wider diameter distribution. For the fibers prepared at PVP/SR speed ratios of 1.7/2.5 and 3.5/2.5 (mL/h), the fibrous structure remained intact after immersion in water for 8 h. The pure SR microfiber could be made from the composite after immersion in water, which can be potentially used as stretchable and selectively permeable membranes for chemical protective applications and in plastics toughening. © 2012 Wiley Periodicals, Inc.

Published: June 2012

AbstractTo predict the final geometry of carbon fiber‐epoxy composite parts, a methodology is introduced that takes into account cure kinetics, cure shrinkage, thermal strains, tool‐part interface, and development of mechanical properties during cure. These parameters affect process‐induced residual stresses and distortion in the parts. A module was developed for each mechanism and a fully 3D coupled thermomechanical finite element analysis was utilized. To validate the simulation results, a square composite panel was fabricated and its pattern of distortion was obtained. The simulated distortion pattern agreed well with the actual pattern obtained from the experiments. Parallel processing and optimization of the developed codes were used resulting in 94% reduction in the computational time. The proposed methodology proved to be accurate and time‐efficient in predicting the final geometry of the parts. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Published: June 2012

AbstractThis study is primarily focused on the possibility to use a sulfur vulcanized low‐molecular weight polybutadiene with isocyanate end groups in the main chain as a matrix for composite materials reinforced with common inorganic particulate fillers (calcium carbonate, titanium dioxide, titanium dioxide modified with zinc, respectively). The isocyanate groups were used for a preliminary crosslinking of the oligomeric polybutadiene with glycerol as a three‐functional crosslinker. The prepared polybutadiene‐based polyurethane gel was subsequently vulcanized with sulfur. It has been shown that the vulcanized liquid polybutadiene could be successfully applied as the matrix for composite materials with inorganic filler. The resulting composite materials exhibited enhanced mechanical properties (tensile strength, flexural strength, hardness) and retain a high chemical resistance against hydrolysis and aqueous solutions of chemicals. © 2012 Wiley Periodicals, Inc.

Open access to the scientific journal literature – status and challenges for the information systems community
Authors: Björk Bo‐Christer , Paetau Patrik 
Published: June 2012

AbstractEditor's SummarySince the 1990s, the aim of open access (OA) has been to enhance scholarly communication by delivering scientific publications on the Internet without fees or restrictions. Adoption of the gold model of OA, electronic access to publishers' scientific journals at no cost, has been slow in the United States and the United Kingdom, even if authors pay an extra OA charge. The more successful route has been green OA, publishing the original or modified versions on authors' personal home pages or in institutional or subject‐specific repositories. In a 2008 sample of science disciplines, Bjork found 20.4% were provided OA, with 8.5% on publishers' sites. For information systems articles published in 2009, 21.3% were OA but a mere 0.6% on publishers' sites, the gold model. Of OA articles, 8% were published on domain repositories, 32.7% in institutional repositories, and 59% on other websites. Broad expansion of OA will depend on greater author awareness and wider platform access, and publishers must adopt international bibliographic metadata and standardized author identification.
Investigating changes in anger and aggression in offenders with high levels of psychopathic traits attending the Chromis violence reduction programme
Authors: Tew J. , Dixon L. , Harkins L. , Bennett A. 
Published: June 2012

ABSTRACTBackgroundChromis was accredited by the Correction Services Accreditation Panel in 2005 as an intervention designed to reduce violence in offenders whose level or combination of psychopathic traits disrupts their ability to engage in treatment and change. It runs as part of the regime in the dangerous and severe personality disorder unit in HM Prison Frankland (Westgate). A multiple case study investigation into changes over time in participants is currently underway, part of which is reported here.AimsThis paper reports on information relating to changes in anger and aggression in Chromis completers.MethodsChange in psychometrics and observed incidents of verbal and physical aggression are considered for five case study participants who have completed Chromis and progressed from Westgate to a different location.ResultsFindings suggest that cases experienced a reduction in self‐reported anger, and expected incidents of physical aggression but had higher than expected levels of verbal aggression after leaving Westgate.ConclusionsThese findings offer cautious optimism for the effectiveness of Chromis, although methodological limitations must also be considered. Findings may be seen as positive indicators of Chromis, or at least the approach to working with these offenders across Westgate, in reducing violence.Implications for practiceFindings support the continued delivery and evaluation of Chromis. There may be benefit in exploring ways to further understand and address verbal aggression in participants. Copyright © 2012 John Wiley & Sons, Ltd.
How Good Are Coarse‐Grained Polymer Models? A Comparison for Atactic Polystyrene
Authors: Karimi‐Varzaneh Hossein Ali , van der Vegt Nico F. A. , Müller‐Plathe Florian , Carbone Paola 
Published: June 2012

AbstractThis review provides an overview of the various coarse‐grained models that have been developed in the past few years for amorphous polystyrene. Different techniques to develop the force fields and different mapping schemes lead to models that perform differently depending on the properties investigated. This review collects and compares the models to guide the reader in the choice of the best model for the application of interest. It is expected that the central features of the various coarse‐graining procedures will also apply to systems other than polystyrene and that some of the conclusions about different coarse‐graining strategies are general.
Is newborn imitation developmentally homologous to later social‐cognitive skills?
Authors: Suddendorf Thomas , Oostenbroek Janine , Nielsen Mark , Slaughter Virginia 
Published: June 2012

AbstractTo assess claims about developmental homologies, or devologies, longitudinal data are needed. Here, we illustrate this with the debate about the purported foundational role of neonatal imitation in children's social and cognitive development. Cross‐sectional studies over the past 35 years have clarified neither the prevalence of imitation in newborns nor its relationships to later developing skills. Thus, scholars have been able to maintain diametrically opposing explanations of neonatal imitation in the literature. Here, we discuss this issue and outline how large‐scale longitudinal approaches promise to resolve such debates and have the potential to use individual difference measures to uncover links to later development. © 2011 Wiley Periodicals, Inc.

AbstractThe basic helix‐loop‐helix (bHLH) transcription factor Ascl1 plays crucial roles in both oligodendrocyte development and neuronal development; however, the molecular target of Ascl1 in oligodendrocyte progenitor cells (OPCs) remains elusive. To identify the downstream targets of Ascl1 in OPCs, we performed gene expression microarray analysis and identified Hes5 as a putative downstream target of Ascl1. In vivo analysis revealed that Ascl1 and Hes5 were coexpressed in early developmental oligodendrocytes in both the telencephalon and the ventral spinal cord. We also found that Hes5 expression was reduced in the OPCs of Ascl1 mutant mice. Furthermore, we demonstrated that Ascl1 directly binds to an E‐box region within the Hes5 promoter and regulates Hes5 expression at the transcriptional level. Taken together, these in vivo and in vitro data suggest that Ascl1 induces Hes5 expression in a cell‐autonomous manner. Considering the previously known function of Hes5 as a repressor of Ascl1, our data indicate that Hes5 is involved in the negative feedback regulation of Ascl1. © 2012 Wiley Periodicals, Inc.

Published: June 2012

AbstractBackgroundOptions for controlling hemostasis during thyroidectomy include bipolar vessel sealing system and ultrasonic technology. The purpose of this study was to compare these energy‐based devices on the performance of open thyroidectomy for benign disease with emphasis given to postoperative parathyroid function.MethodsAmong the available energy‐based devices, the LigaSure Precise (LP; Valleylab, Boulder, CO) and FOCUS Shears (FS; Ethicon Endo‐Surgery, Cincinnati, OH) were evaluated. One hundred ninety‐nine consecutive patients scheduled for open thyroidectomy were prospectively randomized into 2 similar‐sized groups. Operative time, morbidity, incision length, postoperative pain, and hospital stay were analyzed. Postoperative hypoparathyroidism was monitored with serial determinations of intact parathyroid hormone (iPTH) and serum calcium.ResultsEarly postoperative measurement of iPTH plasma level, although within the reference range, was significantly lower in the FS group (p < .001). Oral calcium supplementation was significantly higher and prolonged in the FS group.ConclusionThe present study demonstrates a significant difference of the rates for postoperative parathyroid malfunction when using different energy‐based devices. © 2012 Wiley Periodicals, Inc.

Prognostic factors in head and neck squamous cell carcinoma: Comparison of CHAID decision trees technology and cox analysis
Authors: Avilés–Jurado Francesc Xavier , León Xavier 
Published: June 2012

AbstractBackgroundThe purpose of this study was to compare the risk factors obtained from a classical statistical method (Cox proportional hazards model) and the results obtained with classification trees (Chi‐square Automatic Interaction Detection [CHAID] model) in head and neck squamous cell carcinoma (HNSCC).MethodsWe conducted a retrospective study of 3373 patients with HNSCC and a follow‐up longer than 2 years.ResultsThe most decisive variable classified by CHAID was T category. N classification was an important prognostic factor in the Cox analysis, but this was not considered in CHAID except in T2 and supraglottic T3. CHAID also indicated that women with oral cavity T3/T4 to N0 tumors had poorer prognosis (28%) than men (58.5%; p value < .001). In oropharynx location, men had lower survival than women (41% vs 72%; p value < .001).ConclusionsThe main benefit of CHAID analysis is that it identifies a relatively small number of patients with a singular behavior, which is more discriminatory for an optimal diagnosis and treatment. © 2012 Wiley Periodicals, Inc.

Incidence of level IIB lymph node metastasis in supraglottic laryngeal squamous cell carcinoma with clinically negative neck—A prospective study
Authors: Jia Shenshan , Wang Yanying , He Hongjiang , Xiang Cheng 
Published: June 2012

AbstractBackgroundThe purpose of this study was to determine the incidence of level IIB metastasis in patients with clinically negative (N0) necks with squamous cell carcinoma (SCC) of the supraglottic larynx and to assess whether level IIB lymph nodes may be left undissected in such patients. This was a prospective analysis of a case series.MethodsA prospective analysis of 68 patients with SCC of the supraglottic larynx and N0 neck who underwent surgical treatment of the primary lesion with simultaneous selective neck dissection (SND) of levels II and III. During neck dissection, level IIB lymph nodes were separately removed and processed. Occult metastasis at levels IIA, IIB, and III and the regional recurrence within this area were evaluated.ResultsOne hundred twenty‐two SND (levels II and III) procedures were performed on 68 patients in this series. The occult metastasis rate was 30.9% (21 of 68). The mean number of lymph nodes harvested in level IIB was 4.1 (range, 1–14). In none of the 122 SND specimens (levels II and III) was metastasis found in level IIB either in the ipsilateral or contralateral neck sides. Five patients developed neck recurrence, none of which was in level IIB.ConclusionWhen SND was carried out for patients with SCC of the supraglottic larynx with N0 neck, superselective neck dissection removing lymph nodes in levels IIA and III was adequate. Level IIB lymph node pads may be left undissected so that spinal accessory nerve dysfunction is decreased and operative time reduced. © 2012 Wiley Periodicals, Inc. Head Neck, 2013
