In bioelectrochemical systems where the oxidative current is mediated by microorganisms, it remains unexplored as to whether low-potential substrates (e.g. formate) enable the anode to work at lower potentials. Due to implications to relevant engineering and natural systems, this study evaluated such possibility and underlying causes. The investigation compared voltammograms of the model exoelectrogen (to exclude the interfering factors in undefined cultures) Geobacter sulfurreducens grown with acetate and formate. G. sulfurreducens had an EM (half-saturation potential) of −0.138 ± 0.004 V vs. SHE when consuming acetate; an EM of −0.160 ± 0.002 V when utilizing formate. Such variation usually requires alternation in electrode reductase expressed by bacteria, according to the existing Nernst-Monod model with a single species of electron conduit. For both acetate- and formate-grown biofilm, non-catalytic voltammetries found multiple redox couples with distinct formal potentials. No clear evidence could support a hypothesis that the bacteria synthesized any different electron conduits when the substrate was changed. Significant changes in the relative abundance of high-potential and low-potential electrocatalytically active conduits were not observed as well. However, low-potential conduits showed elevated electrocatalytic activities in the formate-grown biofilm, which might induce the shift in apparent EM.

[Purpose] This study aimed to investigate the effect of shoulder positions and speeds on internal and external rotation torque of college baseball players and age-matched non-players. [Subjects] Twenty first-level collegiate baseball players and 19 college students were recruited. [Methods] A dynamometer system was used to evaluate the shoulder rotation strength in sitting postures. Three testing positions, namely shoulder abduction of 45°, 70°, and 90° in the scapular plane, were combined with three testing speeds at 60°/s, 120°/s, and 210°/s. [Results] The maximum external and internal rotation torques both occurred at shoulder abduction of 70°. However, only external rotation torque was affected by the speed, with the peak value observed at 60°/s. The internal rotation torque of baseball players was larger than that of the control group under all testing conditions, but the external rotation did not show any difference. The ratio of external to internal rotation torque changed with the testing positions and speeds in both groups. The ratio in the control group was greater than that in the player group. [Conclusion] The shoulder position could affect the rotational strength, and the baseball players could strengthen their external rotators for better performance and injury prevention.

The pathogenesis of intervertebral disc (IVD) degeneration is not fully understood. The biomolecular signaling pathways involved in the IVD degeneration require further investigation. The aim of this study was to investigate the expression of NG2 proteoglycan in the degenerated IVD. IVD samples were obtained from 16 Dachshunds that were confirmed to have IVD herniation and subsequently underwent hemilaminectomy. The samples were subjected to histological and immunohistochemical (IHC) examination. IHC revealed positive results for the expression of NG2 proteoglycan in all examined samples. The results showed the expression of NG2 proteoglycan by the degenerated IVDs.

Teleconnection patterns in boreal winter were sought by using the streamfunction based on one-point covariance analysis. As a result, five patterns with two new patterns, i.e., the North and South Pacific Oscillation pattern (PO) and the Middle Atlantic pattern (MA), were obtained. The PO is an interhemispheric pattern with major centers in the Pacific, related to the El Niño/La Niña. The MA has a similar structure with the East Atlantic pattern (EA), though the orientation of the pattern and the difference in the sustaining mechanism, as well as a relatively low correlation between the two indices, distinguish the MA from the EA, with the primary importance of the MA from several pieces of evidence. The PO and MA have significant relations to the surface air temperature mostly through the temperature advection. By comparing the result of the combined EOF for the zonal and meridional winds, the appropriateness of the use of the streamfunction in association with wind variations was also confirmed.

Background:Adverse effects of dietary intake of trans-fatty acids (TFA) on the incidence of coronary artery disease (CAD) are well recognized in Western countries. The risk of TFA, however, has not been well clarified in Japan. We investigated the association of serum TFA concentration with serum lipid profile, coronary risk factors, and prevalence of CAD.Methods and Results:A total of 902 patients, who were hospitalized at Kobe University Hospital from July 2008 to March 2012 and gave written informed consent, were enrolled in this study. Among them, 463 patients had CAD, and 318 patients had metabolic syndrome (MetS). Serum TFA, elaidic acid (trans-9-C18:1) and linolelaidic acid (trans-9, 12-C18:2), were measured on gas chromatography/mass spectrometry. Serum TFA level had a positive correlation with body mass index, waist circumference, low-density lipoprotein cholesterol, triglycerides, and apolipoprotein B48, and an inverse correlation with age and high-density lipoprotein cholesterol. Fasting serum TFA, by age quartile in the young generation with CAD and/or MetS, was higher than that in patients without CAD and/or MetS. On multivariate logistic regression, TFA was identified as a CAD risk after adjustment for classical risk factors.Conclusions:Serum TFA concentration was elevated in young patients with CAD and/or MetS. Diet-derived TFA may cause a serious health problem, particularly in the young generation in Japan.

Measurement of the residual stresses in cold-drawn pearlitic steel wire was conducted using an energy dispersive X-ray diffraction technique. The residual stresses of the ferrite and cementite phases were determined for different crystal orientations and large residual stresses were found to exist in the cold-drawn pearlitic steel wire. The residual stresses in the ferrite phase were compressive in the axial direction but nearly zero in the hoop and radial directions. In addition, the residual stresses of the reflection indices for the ferrite phase were similar to one another. For the cementite phase, while tensile residual stress existed in the axial direction, compressive residual stress existed in the hoop and radial directions. These stresses in the ferrite phase in the axial direction and cementite phase in all directions decreased along the radial positions. A residual stress state model was proposed on the basis of the aligned lamellar structure along the drawing direction; the model explains the effect of the lamellar direction on residual stress. Reanalysis of the wire sample using the proposed model provided residual strains and stresses in the lamellar direction that were different from the average values estimated using the simple stress analysis method.

[Purpose] To assess the evidence for the effectiveness of yoga exercises in the management of headaches. [Subjects and Methods] A search was conducted of six electronic databases to identify randomized controlled trials (RCTs) reporting the effects of yogic intervention on headaches published in any language before January 2015. Quality assessment was conducted using the Cochrane risk of bias tool. [Results] One potential trial was identified and included in this review. The quality critical appraisal indicated a moderate risk of bias. The available data could only be included as a narrative description. Headache intensity and frequency, anxiety and depression scores, and symptomatic medication use were significantly lower in the yoga group compared to the control group. [Conclusion] There is evidence from one RCT that yoga exercises may be beneficial for headaches. However, the findings should be interpreted with caution due to the small number of RCTs. Therefore, further rigorous methodological and high quality RCTs are required to investigate the hypothesis that yoga exercises alleviate headaches, and to confirm and further comprehend the effects of standardized yoga programs on headaches.

Background:The effect of adiposity on response to cardiac resynchronization therapy (CRT) and long-term outcome in patients undergoing CRT has not been previously reported. This study assessed the impact of baseline body mass index (BMI) on cardiac reverse remodeling and prognosis following CRT.Methods and Results:A total of 247 CRT patients were included and divided into 4 groups according to baseline BMI. During 6-month follow-up, overweight and obese patients (BMI, 24–28 kg/m2, ≥28 kg/m2, respectively) were inclined to have better clinical and echocardiographic improvements (P<0.05) as well as higher response rate (P<0.001) than underweight and normal weight patients (BMI, <18.5 kg/m2, 18.5–24 kg/m2, respectively). During long-term follow-up, overweight and obese patients had lower all-cause mortality (P=0.015) and combined endpoint of death or HF hospitalizations (P=0.001) than underweight and normal weight patients. Compared with normal weight patients, underweight patients had a 2.29-fold increase in risk of combined endpoint events whereas overweight and obese patients had a reduction in the risk of death (66% and 58%, respectively) and combined endpoint events (52% and 38%, respectively).Conclusions:Patients with obesity and overweight derived more benefit from CRT. Higher BMI was independently associated with better clinical outcome in CRT patients. (Circ J 2014; 78: 2899–2907)

Ulleungdo and Dokdo are volcanic islands that experience a characteristic marine climate, influenced by warm currents. The richness and diversity of the plant species, particularly vascular plants, are higher on Ulleungdo than on Dokdo. In contrast to the native plant life, little is known about the diversity of soil fungi living in the rhizosphere of these two islands. In this study, we utilized the barcoded pyrosequencing method to analyze rhizosphere soil fungi on Ulleungdo and Dokdo. In total, 768 operational taxonomic units (OTUs) were analyzed from the Ulleungdo samples, while 640 OTUs and 382 OTUs were analyzed from the Dongdo and Seodo (islets of Dokdo) samples, respectively. Species richness was considerably higher in the Ulleungdo samples than in the Dongdo and Seodo samples, while there was little difference in species diversity between the samples. The taxonomic composition analyses demonstrated that members of the phylum Basidiomycota dominated the Ulleungdo samples, whereas members of the phylum Ascomycota were predominant in the Dokdo samples. Ectomycorrhizal fungi belonging to the phylum Basidiomycota, in particular, were more abundant in the Ulleungdo samples. This finding suggests that the difference in the abundance of the ectomycorrhizal fungi in the rhizospheres of Ulleungdo and Dokdo may have been affected by species richness and diversity of the vascular plants. Our study is the first detailed report of the composition of soil fungal communities on the Ulleungdo and Dokdo islands. In addition, our findings provide a basis for understanding the ecological interactions between plants and fungi.

In this paper, we propose an error-correction low-pass filter (EC-LPF) algorithm for estimating the wireless distance between devices. To measure this distance, the received signal strength indication (RSSI) is a popularly used method because the RSSI of a wireless signal, such as Wi-Fi and Bluetooth, can be measured easily without the need for additional hardware. However, estimating the wireless distance using an RSSI is known to be difficult owing to the occurrence of inaccuracies. To examine the inaccuracy characteristics of Bluetooth RSSI, we conduct a preliminary test to discover the relationship between the actual distance and Bluetooth RSSI under several different environments. The test results verify that the main reason for inaccuracy is the existence of measurement errors in the raw Bluetooth RSSI data. In this paper, the EC-LPF algorithm is proposed to reduce measurement errors by alleviating fluctuations in a Bluetooth signal with responsiveness for real-time applications. To evaluate the effectiveness of the EC-LPF algorithm, distance accuracies of different filtering algorithms are compared, namely, a low-pass filer (LPF), a Kalman filter, a particle filter, and the EC-LPF algorithm under two different environments: an electromagnetic compatibility (EMC) chamber and an indoor hall. The EC-LPF algorithm achieves the best performance in both environments in terms of the coefficient of determination, standard deviation, measurement range, and response time. In addition, we also implemented a meeting room application to verify the feasibility of the EC-LPF algorithm. The results prove that the EC-LPF algorithm distinguishes the inside and outside areas of a meeting room without error.

[Purpose] This study aimed to assess the effect of a virtual reality exercise program accompanied by cognitive tasks on the balance and gait of stroke patients. [Subjects] Twenty stroke patients were randomly assigned to two groups 10 to an experimental group that performed a virtual reality exercise program accompanied by cognitive tasks and 10 to a control group. The control group performed a proprioceptive neuromuscular facilitation exercise program. Balance was measured with the Berg Balance Scale. Gait was assessed using the Timed Up and Go Test. The paired t-test was used to compare groups before and after the experiment. The independent t-test was conducted to assess differences in the degree of change between the two groups before and after the experiment. [Results] Within-group comparison in the experimental group showed significant differences in the Berg Balance Scale and Timed Up and Go Test. In a comparison between groups, the differences in the Berg Balance Scale and Timed Up and Go Test in the experimental group appeared significant compared with the control group. [Conclusion] The results of the experiment indicate that a virtual reality exercise program accompanied by cognitive tasks has a positive effect on the balance and gait of stroke patients.

Sarcopenia is an age-related systemic syndrome with progressive deterioration in skeletal muscle functions and loss in mass. Although the senescence-accelerated mouse P8 (SAMP8) was reported valid for muscular ageing research, there was no report on the details such as sarcopenia onset time. Therefore, this study was to investigate the change of muscle mass, structure and functions during the development of sarcopenia. Besides the average life span, muscle mass, structural and functional measurements were also studied. Male SAMP8 animals were examined at month 6, 7, 8, 9, and 10, in which the right gastrocnemius was isolated and tested for ex vivo contractile properties and fatigability while the contralateral one was harvested for muscle fiber cross-sectional area (FCSA) and typing assessments. Results showed that the peak of muscle mass appeared at month 7 and the onset of contractility decline was observed from month 8. Compared with month 8, most of the functional parameters at month 10 decreased significantly. Structurally, muscle fiber type IIA made up the largest proportion of the gastrocnemius, and the fiber size was found to peak at month 8. Based on the altered muscle mass, structural and functional outcomes, it was concluded that the onset of sarcopenia in SAMP8 animals was at month 8. SAMP8 animals at month 8 should be at pre-sarcopenia stage while month 10 at sarcopenia stage. It is confirmed that SAMP8 mouse can be used in sarcopenia research with established time line in this study.

Many countries in Europe and the world have to cope with an aging population. Although health policy in many countries aims at increasing disability-free life expectancy, elderly patients represent a significant proportion of all patients admitted to different hospital departments. The aim of the research was to investigate the relationship between health-related quality of life (HRQOL) and the care dependency status among elderly hospital patients. In 2012, a descriptive survey was administered to a convenience sample of 325 elderly hospital patients (> 60 years) from The Netherlands (N = 125), from Poland (N = 100), and from Turkey (N = 100). We employed the Functional Assessment of Chronic Illness Therapy (FACIT) Measurement System and the Care Dependency Scale. FACIT is a collection of HRQOL questionnaires that assess multidimensional health status in people with various chronic illnesses. From demographic variables, gender (female) (r = −0.13, p < 0.05), age and informal care given by family members (r = −0.27 to 0.27, p < 0.01) were significantly correlated with the care dependency status for the whole samples. All HRQOL variables, hearing aid and duration of illness correlated with care dependency status (r = −0.20 to 0.50, p < 0.01). Moreover, the FACIT sum score (Poland and Turkey) and functional wellbeing (The Netherlands) are significantly associated with the decrease in care dependency status. Thus, the FACIT variables are the most powerful indicators for care dependency. The study provides healthcare professionals insight into improvement of quality of care in all three countries.
