Chang F-H, Wang Y-H, Jang Y, Wang C-W. Factors associated with quality of life among people with spinal cord injury: application of the International Classification of Functioning, Disability and Health Model. Objective: To identify the factors that influence an individual's quality of life (QOL) after spinal cord injury (SCI) based on the International Classification of Functioning, Disability and Health (ICF) framework. Design: Cross-sectional exploratory study. Setting: Taiwan community. Participants: Community-dwelling adults (N=341) who had suffered an SCI at least 1 year previously and were between the ages of 18 and 60 years. Interventions: Not applicable. Main Outcome Measure(s): A combination of self-report questionnaire and interview. The dependent variable, QOL, was measured by the abbreviated version of the World Health Organization Quality of Life, while the independent variables - participation, activity, impairment, and contextual factors - were measured using the Frenchay Activity Index, Barthel Index, and a demographic form. Results: Multivariate analysis results indicated that participation, activity, and marital status are significant factors in the QOL outcome. Results also indicated that among the various factors that affect each domain of QOL (physical health, psychological health, social relationships, and environment), participation was the strongest determinant. Conclusions: The ICF provided an excellent framework with which to explore the factors influencing QOL after SCI. The results demonstrated that marital status, participation, and activity exert the strongest influence on QOL, while impairment and other variables do not directly influence QOL. © 2012 American Congress of Rehabilitation Medicine.

We have examined the spin ordering of an axial next-nearest-neighbor Ising model in two dimensions (2D) near above the antiphase ((2) phase). We considered an NR-replica system and calculated an overlap function qm between different replicas, having used a cluster heat bath Monte Carlo method. We determined transition temperature between the (2) phase and a floating incommensurate (IC) phase as TC2/J=0.89±0.01 with frustration ratio κ(≡-J2/J1)=0.6. We found that the spin state at T TC2 may be called a domain state, because the spin structure is characterized by a sequentially arranged four types of domains with different (2) structures. In the domain state, the 2D XY symmetry of the spin correlation in the IC phase weakly breaks, and the diversity of the spin arrangement increases as T→TC2. The Binder ratio gL exhibits a depression at T∼TC2 and the quasiperiodic spin structure, which is realized in the IC phase, becomes diverse at T TC2. We discussed that the domain state is stable against the thermal fluctuation which brings a two-stage development of the spin structure at low temperatures. © 2017 American Physical Society.

Evaluation of singing skill is a popular function of karaoke machines. Here, we introduce a different aspect of evaluating the singing voice of an amateur singer: "singing enthusiasm". First, we investigated whether human listeners can evaluate singing enthusiasm consistently and whether the listener's perception matches the singer's intended enthusiasm. We then identified three acoustic features relevant to the perception of singing enthusiasm: A-weighted power, "fall-down", and vibrato extent. Finally, we developed a method for combining the selected three features to estimate the value of singing enthusiasm, and obtained a correlation coefficient of 0.65 between the estimated value and human evaluation. © 2013 Elsevier Inc.

The nematode Caenorhabditis elegans changes its chemotaxis to NaCl depending on previous experience. At the behavioral level, this chemotactic plasticity is generated by reversing the elementary behaviors for chemotaxis, klinotaxis, and klinokinesis. Here, we report that bidirectional klinotaxis is achieved by the proper use of at least two different neural subcircuits. We simulated an NaCl concentration change by activating an NaCl-sensitive chemosensory neuron in phase with head swing and successfully induced klinotaxis-like curving. The curving direction reversed depending on preconditioning, which was consistent with klinotaxis plasticity under a real concentration gradient. Cell-specific ablation and activation of downstream interneurons revealed that ASER-evoked curving toward lower concentration was mediated by AIY interneurons, whereas curving to the opposite direction was not. These results suggest that the experience-dependent bidirectionality of klinotaxis is generated by a switch between different neural subcircuits downstream of the chemosensory neuron. © 2014 the authors.

Objectives: The criteria have not yet been established for identifying the configuration of a pure tone audiogram constituting abnormal results that warrant further investigation. The purpose of this study was to determine the prevalence of acoustic neuroma associated with each configuration of the pure tone audiogram in patients with asymmetric sensorineural hearing loss (SNHL). Methods: We performed a retrospective chart review of 500 patients 15 years of age or older who had asymmetric SNHL and had undergone magnetic resonance imaging. Results: The prevalence of acoustic neuroma in these patients was 2.6% (13 of 500). The prevalence of acoustic neuroma in each audiometric configuration was as follows: 7.1% (3 of 42) for a basin-shaped loss (odds ratio [OR] versus overall prevalence, 2.88; p = 0.23; 95% confidence interval [CI], 0.79 to 10.54), 4.7% (5 of 107) for a flat loss, 3.4% (2 of 58) for total deafness, 2.9% (1 of 34) for a high-frequency sloping audiogram, and 2.5% (2 of 81) for a high-frequency steep audiogram. The prevalence in patients with nonimproving idiopathic sudden deafness was 8.1% (OR, 3.29; p = 0.06; 95% CI, 1.13 to 9.55). Conclusions: In conclusion, 2.9% to 8.1% of patients with a characteristic configuration of the pure tone audiogram and symptoms of nonimproving or progressive idiopathic sudden deafness may have acoustic neuroma. © 2010 Annals Publishing Company.

We study the quantum phase transition of an S=12 anisotropic α (≡Jz/Jxy) Heisenberg antiferromagnet on a triangular lattice. We calculate the sublattice magnetization and the long-range helical order parameter and their Binder ratios on finite systems with N≤36 sites. The N dependence of the Binder ratios reveals that the classical 120 Néel state occurs for α 0.55, whereas a critical collinear state occurs for 1/α 0.6. This result is at odds with a widely held belief that the ground state of a Heisenberg antiferromagnet is the 120 Néel state, but it also provides a possible mechanism explaining experimentally observed spin liquids. © 2014 American Physical Society.

Background: Micronutrients are associated with dementia and cognitive decline among older adults. However, nutritional biomarkers of such decline have not been identified. We attempted to identify nutritional biomarkers that were independent risk markers of cognitive decline in a population of older Japanese. Methods: Among 873 cognitively intact adults aged 70 years or older at baseline, 682 (mean age [standard deviation], 75.5 [4.4] years; women 59.7%) were followed for a period of up to 4 years, and nutritional biomarkers in a blood panel were assessed, namely, red blood cell count, hematocrit, mean corpuscular volume, hemoglobin, total cholesterol, high-density lipoprotein cholesterol, hemoglobin A1c, creatinine, albumin, blood glucose, γ-glutamyl transpeptidase, triglyceride, and white blood cell count. Cognition was assessed by the Mini-Mental State Examination, and cognitive decline was defined as a decrease of at least three points on the Mini-Mental State Examination. Results: During an average follow-up of 2.7 years, 115 adults (16.9%) developed cognitive decline. After controlling for important confounders, the odds ratios for cognitive decline in the lowest and middle tertiles of red blood cell count were 2.62 (95% confidence interval: 1.44-4.74) and 2.18 (1.20-3.96), respectively, as compared with the highest tertile. The corresponding odds ratios were 1.81 (1.05-3.22) and 1.03 (0.58-1.83), respectively, for high-density lipoprotein cholesterol and 2.06 (1.14-3.77) and 1.02 (0.54-1.94) for albumin. Conclusions: Low red blood cell count, high-density lipoprotein cholesterol, and albumin were independent risk markers for subsequent cognitive decline in a general population of older adults and may be useful in early clinical screening. © The Author 2014.

TEM of any in situ cells in embedment-free sections-regardless of specimen-fixation methods-clearly shows strand-lattices occupying the cytoplasmic matrix. The cytoplasmic matrix is assumed to be a site of soluble proteins; however, it appears indistinct as conventional TEM cannot target it. Strand-lattices similar to the cytoplasmic ones are duplicated in bovine serum albumin as well as solated gelatin fixed at warm temperatures and at appropriate concentrations, while lattices from gelatin gelated by cooling before fixation are much more compact than those from solated gelatin at a given concentration. Based on the finding of the in vitro proteins, a new interpretation of cell ultrastructures in embedment-free section TEM is proposed: first, differences in the compactness of cytoplasmic lattices represent those in the protein concentration in the cytoplasmic matrix; second, when loose and compact lattices are contiguous within a cell, the cytoplasmic matrix domain occupied by the compact lattice is in a gel state while the remaining domain of the same cell is in a sol state. The explanation for the states of the gel and sol based on the lattice-compactness is applicable to changes in the lattice-compactness of the cytoplasmic matrix of neurohypophyseal axons under intense secretion. © 2010 Elsevier B.V.

The aim of this study was to clarify relationships between participation in community activities and psychosocial and physical health of community-dwelling elderly. The participants of the present study were 413 people selected on the basis of a random 1/3 extraction of people aged 65 or older and living in a rural community in Miyagi prefecture. The baseline survey was conducted in February 2008. One year later, we conducted a follow-up survey to clarify how participation in community activities influenced the elderly. Finally, we analyzed data for 218 people, focusing on influences on psychosocial and physical health using the logistic regression model. The state of community activity was treated as a dependent variable, and mental and physical health indicators were assessed as the independent variables. Of the elderly sample, 63 persons were found to be frequent participants in community activities, 60 were infrequent participants, and 95 did not participate. The frequently participating individuals displayed significantly better results for declines in depression (OR = 0.34, 95% CI: 0.13-0.89), and social participation (OR = 0.12, 95% CI: 0.05-0.29), as well as the TMIG index of competence (OR = 0.26, 95% CI: 0.08-0.78) as compared with those who did not participate. These results suggest that community activities prevent deterioration of mental health, improve social health, and maintain higher-level functional capacity among community-dwelling elderly individuals.
