Abstract
Since there is an upper limit to skill improvement through the repetition of actual execution, we examined whether motor imagery could be used in combination with actual execution to maximize motor skill improvement. Fingertip dexterity was evaluated in 25 healthy participants performing a force adjustment task using a pinch movement with the left thumb and index finger. In the intervention condition, six sets of repetitions of combined actual execution and motor imagery were performed, while in the control condition, the same flow was performed, but with motor imagery replaced by rest. Changes in the excitability of spinal motoneurons during motor imagery compared to rest were compared in terms of the F/M amplitude ratio. Motor skill changes were compared before and after repeated practice and between the conditions, respectively, using the absolute amount of adjustment error between the target pinch force value and the delivered pinch force value (absolute error) as an index. The results showed that the repetition of exercise practice and motor imagery decreased the absolute error, which was greater than that of exercise practice alone in terms of motor skill improvement. The F/M amplitude ratio for motor imagery compared to rest did not increase. This suggests that motor imagery is involved in the degree of the increase of spinal motoneuron excitability based on the real-time prediction of motor execution and that there may be no need for an increase in excitability during motor skill control.

Abstract
INTRODUCTION Patients with total knee arthroplasty occasionally develop postoperative abnormalities such as posttraumatic knee stiffness and arthrofibrosis, which may affect activities of daily living. However, there are no clear assessment methods or interventions for knee stiffness. Musculoskeletal ultrasound imaging enables real-time evaluation of mobility and flexibility of tissues. The purpose of this case report was to describe the use of musculoskeletal ultrasound imaging for evaluating the optimal location and methods of passive manipulation. CASE DESCRIPTION The patient was an 82-year-old woman who had undergone total knee arthroplasty. She was unable to climb stairs due to limited knee flexion. Based on the results of musculoskeletal ultrasound imaging assessment, we hypothesized that the knee flexion limitation was caused by decreased sliding movement of the suprapatellar pouch. Hence, we performed passive manipulation on the tissue with decreased sliding under musculoskeletal ultrasound guidance. OUTCOMES The patient's knee flexion angle increased from 90° to 110° within 1 week of intervention, and her gait speed improved from 16.48 to 13.2 s per 10 m. Furthermore, after the intervention, she was able to climb 10 steps using a handrail. DISCUSSION Ultrasound imaging is important because it allows the examination of tissues with mobility changes such as in arthrofibrosis. Our work highlights the use of musculoskeletal ultrasound imaging for identifying the target region for therapy and for providing guidance during passive manipulation.

Abstract
[Purpose] This study aimed to examine the effects of unilateral vibratory stimulation on contralateral homonymous muscle. [Participants and Methods] The study included 14 participants without a history of any disease. Participants were tested under three separate conditions: vibratory stimulation, pressure stimulation, and rest. F-waves were measured at two time points for 15 seconds in the rest position under each of the testing conditions. [Results] The F/M amplitude ratio analysis showed interactions between the vibratory stimulation‒pressure stimulation and vibratory stimulation‒rest conditions. The F-wave persistence analysis demonstrated interactions between the vibratory and pressure stimulation conditions. Vibratory stimulation significantly decreased the F/M amplitude ratio and F-wave persistence at two time points, before and during the stimulation. [Conclusion] The vibratory stimulation used in this study could suppress the contralateral homonymous muscle tone.

Abstract
Strategies are critical to promote child participation in important life activities. This study analyzed the participation strategies of the parents of children with neurodevelopmental disorders. Ninety-two Japanese elementary children with neurodevelopmental disorders and their parents were recruited. The parents completed the Participation and Environment Measure for Children and Youth (PEM-CY) questionnaire. Strategy text data obtained from the PEM-CY were analyzed with the co-occurrence network and correspondence analyses. The co-occurrence network analysis showed that the commonality of strategies to enable participation at home, school, and community settings was able to explain the child's characteristics when involved in each setting. The correspondence analysis also suggested the need for specific strategies in each setting. The importance of strategies to improve the attitudinal environment and promote the participation of children with neurodevelopmental disorders was evident. Reducing stigma is important in all environments, especially in the public sphere. In addition, specific strategies are needed in each setting, suggesting the importance of context-specific approaches.

Abstract
IMPORTANCE An association between sensory processing difficulties and behavioral problems among children has been reported in previous studies. Sleep problems among children can lead to both externalizing and internalizing behavioral problems. However, the relationships between sensory processing and sleep among children are not well understood. OBJECTIVE To develop a structural causal model (SCM) predicated on the hypothesis that sensory processing difficulties and sleep problems are closely related among preschoolers and may contribute to behavioral issues. DESIGN Cross-sectional study. PARTICIPANTS A total of 168 children ages 3-5 yr who were enrolled in a preschool or an accredited kindergarten (four facilities in total) in a Japanese prefecture participated in the analysis. OUTCOMES AND MEASURES After gaining the cooperation of educators, we distributed the following items to the children's parents: an informed consent form, the Short Sensory Profile-Japanese version (SSP-J), the Japanese Sleep Questionnaire for Preschoolers (JSQ-P), and the Child Behavior Checklist for Ages 1.5-5. Through factor analysis of the SSP-J and the JSQ-P, we identified common factors. We developed an SCM using structural equation modeling. RESULTS Four factors were identified by factor analysis: attention deficit, sensory sensitivity, sleep problems, and restless legs syndrome symptoms. The final structural equation modeling analysis had an acceptable goodness of fit (goodness-of-fit index = .862; root-mean-square error of approximation = .087). CONCLUSIONS AND RELEVANCE The model suggests that sensory sensitivity and sleep difficulties may contribute to behavioral issues among preschoolers. Plain-Language Summary: The results of this study suggest that relationships exist between behavioral problems, sensory processing, and sleep among preschoolers. The authors developed a model that identified four common factors that contribute to behavioral issues among preschoolers: attention deficit, sensory sensitivity, sleep problems, and restless legs syndrome symptoms. Children's behavioral problems are an important consideration for occupational therapy practitioners working with preschoolers. Sensory processing and sleep must be accurately evaluated to address preschoolers' behavioral issues.

Abstract
Malaria infection elicits both protective and pathogenic immune responses, and IL-27 is a critical cytokine that regulate effector responses during infection. Here, we identified a critical window of CD4+ T cell responses that is targeted by IL-27. Neutralization of IL-27 during acute infection with Plasmodium chabaudi expanded specific CD4+ T cells, which were maintained at high levels thereafter. In the chronic phase, Plasmodium-specific CD4+ T cells in IL-27-neutralized mice consisted mainly of CD127+ KLRG1- and CD127- KLRG1+ subpopulations that displayed distinct cytokine production, proliferative capacity, and are maintained in a manner independent of active infection. Single-cell RNA-seq analysis revealed that these CD4+ T cell subsets formed independent clusters that express unique Th1-type genes. These IL-27-neutralized mice exhibited enhanced cellular and humoral immune responses and protection. These findings demonstrate that IL-27, which is produced during the acute phase of malaria infection, inhibits the development of unique Th1 memory precursor CD4+ T cells, suggesting potential implications for the development of vaccines and other strategic interventions.

Abstract
PURPOSE To investigate the incidence of postoperative cerebral infarction after curative lobectomy, its association with the type of lobectomy, and how postoperative new-onset arrhythmia contributes to postoperative cerebral infarction. METHODS The subjects of this analysis were 77,060 patients who underwent curative lobectomy for lung cancer between 2016 and 2018 according to the National Clinical Database. Incidences of postoperative cerebral infarction and postoperative new-onset arrhythmia were analyzed. Moreover, mediation analysis was performed to evaluate the causal pathway between postoperative new-onset arrhythmia and postoperative cerebral infarction. RESULTS Postoperative cerebral infarction occurred in 110 (0.7%) patients after left upper lobectomy and in 85 (0.7%) patients after left lower lobectomy. Left upper lobectomy and left lower lobectomy were associated with a higher likelihood of postoperative cerebral infarction than right lower lobectomy. Left upper lobectomy was the strongest independent predictor of postoperative new-onset arrhythmia. However, in the mediation analysis, the odds ratio for cerebral infarction did not change after the addition of the factor of postoperative new-onset arrhythmia. CONCLUSION Cerebral infarction occurred significantly more often not only after left upper lobectomy, but also after left lower lobectomy. Postoperative new-onset arrhythmia was less likely to be related to cerebral infarction after left upper lobectomy.

Abstract
The genus Mansonella Faust, 1929 includes 29 species, mainly parasites of platyrrhine monkeys in South America and anthropoid apes in Africa. In Malaysia, Mansonella (Tupainema) dunni (Mullin & Orihel, 1972) was described from the common treeshrew Tupaia glis Diard & Duvaucel (Scandentia). In a recent classification of the genus Mansonella, seven subgenera were proposed, with M. (Tup.) dunni as a monotypic species in the subgenus Tupainema. In this study, we collected new material of M. (Tup.) dunni from common treeshrews in Peninsular Malaysia and redescribed the morphological features of this species. We found that M. (Tup.) dunni differs from M. (Cutifilaria) perforata Uni et al., 2004 from sika deer Cervus nippon (Cetartiodactyla) in Japan, with regards to morphological features and predilection sites in their respective hosts. Based on multi-locus sequence analyses, we examined the molecular phylogeny of M. (Tup.) dunni and its Wolbachia genotype. Species of the genus Mansonella grouped monophyletically in clade ONC5 and M. (Tup.) dunni was placed in the most derived position within this genus. Mansonella (Tup.) dunni was closely related to M. (M.) ozzardi (Manson, 1897) from humans in Central and South America, and most distant from M. (C.) perforata. The calculated p-distances between the cox1 gene sequences for M. (Tup.) dunni and its congeners were 13.09% for M. (M.) ozzardi and 15.6-16.15% for M. (C.) perforata. The molecular phylogeny of Mansonella spp. thus corroborates their morphological differences. We determined that M. (Tup.) dunni harbours Wolbachia endosymbionts of the supergroup F genotype, in keeping with all other Mansonella species screened to date.

Abstract
BACKGROUND Giant mediastinal mature teratomas may cause airway obstruction or decreased venous return due to the mass effect. Preoperative stabilization of the respiratory and circulatory systems is important for perioperative management to safely perform surgery, including general anesthesia. However, to the best of our knowledge, there are only a few reports regarding the preoperative computed tomography (CT)-guided drainage of mediastinal tumors. CASE PRESENTATION A 30-year-old woman was admitted to the emergency room with sudden dyspnea. CT findings revealed a giant cystic mass in the anterior mediastinum compressing the trachea and the right main bronchus. The patient was intubated and CT-guided drainage of the fluid content of the cyst was performed to decompress the airway obstruction. Thereafter, the mediastinal tumor was resected during elective surgery and pathologically diagnosed as a mature teratoma. CONCLUSIONS Rescue preoperative CT-guided drainage of a giant mediastinal mature teratoma allowed safe general anesthesia and surgery by releasing the airway obstruction.

Abstract
Mental rotation (MR) is a well-established experimental paradigm for exploring human spatial ability. Although MR tasks are assumed to be involved in several cognitive processes, it remains unclear which cognitive processes are related to the individual ability of motor adaptation. Therefore, we aimed to elucidate the relationship between the response time (RT) of MR using body parts and the adaptive motor learning capability of gait. In the MR task, dorsal hand, palmar plane, dorsal foot, and plantar plane images rotated in 45° increments were utilized to measure the RTs required for judging hand/foot laterality. A split-belt treadmill paradigm was applied, and the number of strides until the value of the asymmetrical ground reaction force reached a steady state was calculated to evaluate the individual motor adaptation ability. No significant relationship was found between the mean RT of the egocentric perspectives (0°, 45°, and 315°) or allocentric perspectives (135°, 180°, and 225°) and adaptive learning ability of gait, irrespective of body parts or image planes. Contrarily, the change rate of RTs obtained by subtracting the RT of the egocentric perspective from that of the allocentric perspective in dorsal hand/foot images that reflect the time to mentally transform a rotated visual stimulus correlated only with adaptive learning ability. Interestingly, the change rate of RTs calculated using the palmar and plantar images, assumed to reflect the three-dimensional transformation process, was not correlated. These findings suggest that individual differences in the processing capability of visual stimuli during the transformation process involved in the pure motor simulation of MR tasks are precisely related to individual motor adaptation ability.

Abstract
The interface between conventional semiconductors and aqueous ionic solutions is an important target in chemistry and materials science. Recently, a wide variety of research has been done on transition-metal dichalcogenides (TMDCs) for use as 2D layered semiconductors, and their optoelectronic properties have been widely explored. One representative TMDC, monolayer (1L) MoS2, is known to show a photoluminescence (PL) signal of a direct band gap nature, and the PL intensity is dependent on the carrier concentration. Various methods of 1L MoS2 carrier modulation have been shown to enhance the PL intensity in dry environments. In contrast, enhancement in an aqueous environment is limited, and a strategy to design an interface with aqueous media has not yet been established. One proposed idea was an aqueous acid interface; however, the enhancement of the PL with this method was usually minimal, about 1 order of magnitude. In this study, we demonstrate a method to achieve strong PL enhancement in 1L MoS2 in an aqueous media by incorporating bis(trifluoromethane)sulfonyl anion (TFSI- ion) in an acidic environment. With the addition of the TFSI- ion in an acidic environment, the enhancement factor of the PL in 1L MoS2 is more than 100 times greater than its PL intensity in water. The molecular anion is the key factor, as the TFSI- ion facilitates the oxidation of MoS2. This anionic effect is the additional factor needed to modulate the optoelectronic properties of 2D semiconductors in aqueous media. The proposed idea could have potential applications for biochemical sensors in aqueous situations.

Abstract
Reports of zoonotic infections caused by the filarial nematode Onchocerca japonica have recently increased in Japan. A 69-year-old woman living in Sosa City, Chiba Prefecture, Kanto Region, Honshu, developed a painful nodule at the metacarpophalangeal joint of the index finger of her right hand. The causative agent was identified as a female O. japonica based on the histopathological characteristics (i.e., cuticle with transverse triangular ridges but without inner striae) of the biopsy specimens of the nodule. The species identification was corroborated by cox1 gene sequencing of the worm tissues isolated from paraffin-embedded sections of the specimens. Subsequent to the excision of the nodule, followed by anthelmintic treatment, the patient remained asymptomatic. Human infection with O. japonica has not previously been reported in Kanto Region, Eastern Honshu. The present case is likely linked to the recent expansion of the geographic range of the Japanese wild boar into this area.

Abstract
The effects of physical exercise on cognitive tasks have been investigated. However, it is unclear how different exercise intensities affect the neural activity. In this study, we investigated the neural activity in the prefrontal cortex (PFC) by varying the exercise intensity while participants performed a dual task (DT). Twenty healthy young adults performed serial subtraction while driving a cycle ergometer. Exercise intensity was set to one of three levels: low, moderate, or high intensity. We did not find any significant change in PFC activity during DT under either the control (no exercise) or low-intensity conditions. In contrast, we observed a significant increase in PFC activity during DT under moderate- and high-intensity conditions. In addition, we observed complex hemodynamics after DT. PFC activity decreased from baseline after DT under the control condition, while it increased under the low-intensity condition. PFC activity remained higher than the baseline level after DT under the moderate-intensity condition but returned to baseline under the high-intensity condition. The results suggest that moderate-intensity exercise with a cognitive load effectively increases PFC activity, and low-intensity exercise may increase PFC activity when combined with a cognitive load.

Abstract
Background Thrombosis in the pulmonary vein stump (PVS) is not a well-known complication after pulmonary lobectomy, but it has the potential to cause embolism to vital organs. The aim of this study was to evaluate the risk factors for thrombosis in the PVS after pulmonary lobectomy. Methods A total of 439 patients who underwent pulmonary lobectomy from 2008 to 2017 were retrospectively reviewed, and 412 patients were further analyzed. The state of the PVS was evaluated by chest contrast-enhanced computed tomography (CECT). Univariate analysis was performed to evaluate the potential risk factors for thrombosis in the PVS. Results Thrombosis in the PVS was detected in 6 of 412 (1.5%) patients, and 5 of them underwent left upper lobectomy (LUL) (5/100, 5.0%) (P = 0.004). In the analyses of the LUL group, postoperative chest radiotherapy was identified as a risk factor for thrombosis in the PVS (P = 0.024), and postoperative atrial fibrillation showed a tendency to be a risk factor for thrombosis (P = 0.058). Conclusions Chest radiotherapy after LUL is a possible risk factor for thrombosis in the PVS. Periodic chest CECT is recommended after postoperative chest radiotherapy for patients after LUL.

Abstract
Plasmodium parasites that infect humans are highly polymorphic, and induce various infections ranging from asymptomatic state to life-threatening diseases. However, how the differences between the parasites affect host immune responses during blood-stage infection remains largely unknown. We investigated the CD4 + T-cell immune responses in mice infected with P. berghei ANKA (PbA) or P. chabaudi chabaudi AS (Pcc) using PbT-II cells, which recognize a common epitope of these parasites. In the acute phase of infection, CD4 + T-cell responses in PbA-infected mice showed a lower involvement of Th1 cells and a lower proportion of Ly6C lo effector CD4 + T cells than those in Pcc-infected mice. Transcriptome analysis of PbT-II cells indicated that type I interferon (IFN)-regulated genes were expressed at higher levels in both Th1- and Tfh-type PbT-II cells from PbA-infected mice than those from Pcc-infected mice. Moreover, IFN-α levels were considerably higher in PbA-infected mice than in Pcc-infected mice. Inhibition of type I IFN signaling increased PbT-II and partially reversed the Th1 over Tfh bias of the PbT-II cells in both PbA- and Pcc-infected mice. In the memory phase, PbT-II cells in PbA-primed mice maintained higher numbers and exhibited better recall response to the antigen. However, recall responses were not significantly different between the infection groups after re-challenge with PbA, suggesting the effect of inflammatory environment by the infection. These observations suggest that the differences in Plasmodium-specific CD4 + T-cell responses between PbA- and Pcc-infected mice were associated with the difference in type I IFN production during the early phase of the infection.

Abstract
To advance our knowledge on the motor system during cyclic gait observation, we aimed to explore the effects of gaze fixation on corticospinal excitability evaluated by single-pulse transcranial magnetic stimulation (TMS). Fourteen healthy adult volunteers watched a video of a demonstrator walking on a treadmill under three different conditions: (1) observing the right lower limb, (2) observing the right ankle joint, and (3) observing the right lower limb on a video focused on the area below the knee. In each condition, motor-evoked potentials elicited by TMS in the tibialis anterior (TA) muscle were measured synchronously with the demonstrator’s initial contact and toe-off points. Directing visual attention to the ankle joint and focusing on its movements caused corticospinal facilitation in the TA muscle compared with watching the video without any visual fixation. In addition, phase-dependent differences in corticospinal excitability between the initial contact and toe-off points were only detected when the visibility range was restricted to below the knee. Our findings indicated that motor resonance during cyclic gait observation is modulated by visual attention and motion visibility in different activation manners.

Abstract
Upon activation, specific CD4+ T cells up-regulate the expression of CD11a and CD49d, surrogate markers of pathogen-specific CD4+ T cells. However, using T-cell receptor transgenic mice specific for a Plasmodium antigen, termed PbT-II, we found that activated CD4+ T cells develop not only to CD11ahiCD49dhi cells, but also to CD11ahiCD49dlo cells during acute Plasmodium infection. CD49dhi PbT-II cells, localized in the red pulp of spleens, expressed transcription factor T-bet and produced IFN-γ, indicating that they were type 1 helper T (Th1)-type cells. In contrast, CD49dlo PbT-II cells resided in the white pulp/marginal zones and were a heterogeneous population, with approximately half of them expressing CXCR5 and a third expressing Bcl-6, a master regulator of follicular helper T (Tfh) cells. In adoptive transfer experiments, both CD49dhi and CD49dlo PbT-II cells differentiated into CD49dhi Th1-type cells after stimulation with antigen-pulsed dendritic cells, while CD49dhi and CD49dlo phenotypes were generally maintained in mice infected with Plasmodium chabaudi. These results suggest that CD49d is expressed on Th1-type Plasmodium-specific CD4+ T cells, which are localized in the red pulp of the spleen, and can be used as a marker of antigen-specific Th1 CD4+ T cells, rather than that of all pathogen-specific CD4+ T cells.

Abstract
Reports of zoonotic infections with Onchocerca japonica (Nematoda: Filarioidea), which parasitizes the Japanese wild boar, Sus scrofa leucomystax, have recently increased in Japan. To predict the occurrence of infection in humans, it is necessary to determine the prevalence of O. japonica infection in the natural host animals. We investigated the presence of adult worms in the footpads, and of microfilariae in skin snips, taken from the host animals, between 2000 and 2018. Onchocerca japonica was found in 165 of 223 (74%) Japanese wild boars in Honshu and Kyushu. Among the nine regions studied, the highest prevalence of O. japonica infection was found in Oita, Kyushu, where 47 of 52 (90.4%) animals were infected. The ears were the predilection sites for O. japonica microfilariae. Adult worms of O. japonica were found more frequently in the hindlimbs than in the forelimbs of the host animals. Onchocerca takaokai was found in 14 of 52 (26.9%) Japanese wild boars in Oita. In Kakeroma Island among the Nansei Islands, both O. japonica and O. takaokai were isolated from the Ryukyu wild boar, S. s. riukiuanus. These observations could help predict future occurrences of human zoonotic onchocercosis in Japan.

Abstract
Background Adjuvant chemotherapy with platinum‐based regimens for completely resected early‐stage non‐small cell lung cancer (NSCLC) provides overall survival benefit in several clinical trials. Objectives We conducted this prospective study to evaluate the efficacy and safety of adjuvant chemotherapy with carboplatin and S‐1 for patients with completely resected stage II to IIIA NSCLC. Methods Patients with completely resected stage IIA to IIIA NSCLC were treated with four cycles of carboplatin with area under the concentration time curve of 5 mg/mL/min on day 1 plus S‐1 at 80–120 mg/bodyweight per day for two weeks, followed by one‐week rest as adjuvant chemotherapy. The primary endpoint was the completion rate of three cycles of the treatment. The secondary endpoints were safety and two‐year survival rate. Results A total of 19 patients were enrolled, until the study was terminated prematurely because of fatal pulmonary embolism in two patients. The median number of treatment cycles was three (range: 1–4). The completion rate of three cycles was 78.9% (95% confidence interval [CI]: 56.6–91.4%). Two‐year disease‐free survival rate was 57.8%. Grade 3 or 4 hematological toxicities included neutropenia (26.2%), anemia (5.2%), and thrombocytopenia (15.7%). Grade 3 or 4 nonhematological toxicities were anorexia (10.5%) and nausea (10.5%). Febrile neutropenia developed in 5.2%. In two patients (10.5%), grade five pulmonary embolism was observed, and the causal relationship with treatment could not be denied. Conclusions Carboplatin and oral S‐1 had modest survival benefit, but this regimen was not tolerable in an adjuvant setting because fatal pulmonary embolism occurred in two patients. Key points Carboplatin and oral S‐1 had modest survival benefit but this regimen was not tolerable. Fatal pulmonary embolism occurred in this regimen.

Abstract
Transcranial magnetic stimulation (TMS) has been widely utilized to noninvasively explore the motor system during the observation of human movement. However, few studies have characterized motor cortex activity during periodic gait observation. Thus, this study examined the effects of an observer's visual experience and/or intention to imitate on corticospinal excitability during the observation of another's gait. Twenty-six healthy volunteers were included in this study and allocated to two different groups. Participants in the visual experience group had formal experience with gait observation (physical therapist training), while those in the control group did not. Motor-evoked potentials induced by TMS in the tibialis anterior and soleus muscles were measured as surrogates of corticospinal excitability. Participants were seated and, while resting, they observed a demonstrator's gait or observed it with the intention to subsequently reproduce it. Compared with the resting state, cyclic gait observation led to significant corticospinal facilitation in the tibialis anterior and soleus muscles. However, this pattern of corticospinal facilitation in the measured muscles was not coupled to the pattern of crural muscle activity during actual gait and was independent of the step cycle. This motor cortex facilitation effect during gait observation was enhanced by the observer's visual experience in a manner that was not step cycle-dependent, while the observer's intent to imitate did not affect corticospinal excitatory input to either muscle. In addition, visual experience did not modulate corticospinal excitability in gait-related crural muscles. Our findings indicate that motor cortex activity during gait observation is not in line with the timing of muscle activity during gait execution and is modulated by an individual's gait observation experience. These results suggest that visual experience acquired from repetitive gait observation may facilitate the motor system's control on bipedal walking, but may not promote the learning of muscle activity patterns.

Abstract
Objectives: Increasing activity levels in older people is important for maintaining quality of life and ameliorating the risks of morbidity related to falls, depression, and dementia. This study aimed to clarify the seasonal variation effects on total energy expenditure, number of steps, time spent in low- and moderate- or high-intensity physical activities, and daily activities performed. Patients and Methods: This was a cross-sectional study of 22 community-dwelling older individuals (3 men, 19 women; mean age, 75.1 ± 7.3 years) living in three districts of Gero, Gifu, who participated in the Gero Salon Project hosted by the Social Welfare Councils. Evaluations were conducted in each season from September 2016 to August 2017. We used a uniaxial accelerometer, the Lifecorder device, which measures physical activity, and the Physical Activity Scale for the Elderly to evaluate activities of daily living. Data were analyzed using the multiple comparisons (Bonferroni correction) method. Results: Total energy expenditure and time spent in moderate- or high-intensity activities did not show seasonal variations. However, the lowest number of steps was taken during the winter, and the number of steps increased significantly from winter to spring. The time spent in low-intensity physical activities was significantly longer in the spring and summer than in the winter. There was no significant seasonal difference in total Physical Activity Scale for the Elderly score, leisure activities, domestic activities, or work-related activities. However, there was a significant difference between the summer and winter scores in "outdoor gardening," with the lowest score observed during the winter. Conclusions: With climate changes in the winter months, "outdoor gardening" becomes difficult, thus decreasing the number of steps taken. Therefore, it is necessary to identify other ways for older people to maintain physical activity during the winter season.

Abstract
IL-27, a regulatory cytokine, plays critical roles in the prevention of immunopathology during Plasmodium infection. We examined these roles in the immune responses against Plasmodium chabaudi infection using the Il-27ra-/- mice. While IL-27 was expressed at high levels during the early phase of the infection, enhanced CD4+ T cell function and reduction in parasitemia were observed mainly during the chronic phase in the mutant mice. In mice infected with P. chabaudi and cured with drug, CD4+ T cells in the Il-27ra-/- mice exhibited enhanced CD4+ T-cell responses, indicating the inhibitory role of IL-27 on the protective immune responses. To determine the role of IL-27 in detail, we performed CD4+ T-cell transfer experiments. The Il-27ra-/- and Il27p28-/- mice were first infected with P. chabaudi and then cured using drug treatment. Plasmodium-antigen primed CD4+ T cells were prepared from these mice and transferred into the recipient mice, followed by infection with the heterologous parasite P. berghei ANKA. Il-27ra-/- CD4+ T cells in the infected recipient mice did not produce IL-10, indicating that IL-10 production by primed CD4+ T cells is IL-27 dependent. Il27p28-/- CD4+ T cells that were primed in the absence of IL-27 exhibited enhanced recall responses during the challenge infection with P. berghei ANKA, implying that IL-27 receptor signaling during the primary infection affects recall responses in the long-term via the regulation of the memory CD4+ T cell generation. These features highlighted direct and time-transcending roles of IL-27 in the regulation of immune responses against chronic infection with Plasmodium parasites.

Abstract
Left upper lobectomy (LUL) has been considered to have a higher risk of thrombus formation in the pulmonary vein stump (PVS) than other lobectomies. A case of thrombus formation in the PVS and right renal infarction detected by contrast-enhanced computed tomography (CECT) 12 days after LUL is presented. The thrombus in the PVS was considered to be related to the renal infarction because of the lack of other potential explanations. After intravenous heparin treatment for 1 week and continuous oral anticoagulation, the thrombus in the PVS became smaller 3 months after the operation, and it basically disappeared after 1 year. Scar formation was detected in the area of renal infarction 3 months after the operation, and no specific change was detected from then on. One should consider performing postoperative chest and abdominal CECT routinely within 1 week after LUL, and, if thrombosis is found, antithrombotic therapy might then be given.

Abstract
Background Occult nodal metastasis results in a poor prognosis for lung cancer patients. The aim of this study was to develop an efficient approach for predicting occult nodal metastasis in peripheral clinical stage I lung adenocarcinoma. Methods Data for 237 peripheral clinical stage I lung adenocarcinoma patients who underwent complete resection were retrospectively reviewed. Univariate and multivariate analyses were performed to investigate predictors of occult nodal metastasis. Kaplan-Meier analysis was performed for survival. Results Occult nodal metastasis was detected in 26/237 (11.0%) patients. Nodule type, tumor SUVmax, whole tumor size, solid tumor size, and preoperative serum carcinoembryonic antigen (CEA) were identified as preoperative predictors of occult nodal metastasis (all P<0.05). Solid tumor size (P<0.001) and preoperative serum CEA (P=0.004) were identified as independent predictors on multivariate analysis. A prediction model was established using the independent predictors. The occult nodal metastasis rate was 2.4% with solid tumor size ≤2.3 cm (low-risk group), 17.0% with solid tumor size >2.3 cm and CEA ≤5 ng/mL (moderate-risk group), and 56.0% with solid tumor size >2.3 cm and CEA >5 ng/mL (high-risk group). The occult nodal metastasis rate was significantly higher in papillary-predominant (11.0%) and solid-predominant subtypes (28.6%; P=0.001). Patients having a micropapillary component had a significantly higher occult nodal metastasis rate (24.2%) compared with no micropapillary component (P=0.007). Histological subtype with micropapillary component and all preoperative predictors were significant prognostic factors affecting disease-free survival (DFS) (all P<0.05). Conclusions A novel approach to predict occult nodal metastasis was developed for peripheral clinical stage I lung adenocarcinoma. It would be helpful for selecting candidates for stereotactic ablative radiotherapy (SABR) or wedge resection and mediastinoscopy or endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA). Complete nodal dissection should be performed for moderate to high-risk patients or patients with poor histologic subtypes.

Abstract
A high-resolution display panel comes to practical use, but the resolution of the indicated contents does not change. The up-sampling processing is applied to indication of the low-resolution contents. In the up-sampling process, the super resolution enables an up-sampling process which estimates information of high frequency components lost by sampling while analyzing input images is noticed. In this paper, we aimed at reconstructing an image of normal resolution in which the influence of statistical noise is reduced by applying super resolution after down-sampling processing is applied to positron emission tomography (PET) image with many statistical noises. To evaluate the noise reduction effect, we compared it with the Gaussian filter which is frequently used to reduce the influence of the statistical noise of the PET image. A 3D Hoffman brain phantom was used to evaluate objectively by peak signal-to-noise ratio and power spectral density. The objective index of the PET image applying super resolution is positive results, suggesting the possibility of being useful as compared with the conventional method.

Abstract
Malaria is induced by infection with Plasmodium parasites, which are genetically diverse, and the immune response to Plasmodium infection has both allele-specific and cross-reactive components. To determine the role of the cross-reactive immune response in the protection and disease manifestation in heterologous Plasmodium infection, we used infection models of P. chabaudi chabaudi (Pcc) and P. berghei ANKA (PbA). CD4+ T cells primed with Pcc infection exhibited strong cross-reactivity to PbA antigens. We infected C57BL/6 mice with Pcc and subsequently treated them with an anti-Plasmodium drug. The Pcc-primed mice exhibited reduced parasitemia and showed no signs of experimental cerebral malaria after infection with PbA. CD4+ T cells from the Pcc-primed mice produced high levels of IFN-γ and IL-10 in response to PbA early after PbA infection. The blockade of IL-10 signaling with anti-IL-10 receptor antibody increased the proportion of activated CD4+ and γδ T cells and the IFN-γ production by CD4+ T cells in response to PbA antigens, while markedly reducing the levels of parasitemia. In contrast, IL-10 blockade did not have a significant effect on parasitemia levels in unprimed mice after PbA infection. These data suggest a potent regulatory role of IL-10 in the cross-reactive memory response to the infection with heterologous Plasmodium parasites leading to the inhibition of the protective immunity and pathogenesis.

Abstract
Adaptive immune responses are critical for protection against infection with Plasmodium parasites. The metabolic state dramatically changes in T cells during activation and the memory phase. Recent findings suggest that metformin, a medication for treating type-II diabetes, enhances T-cell immune responses by modulating lymphocyte metabolism. In this study, we investigated whether metformin could enhance anti-malaria immunity. Mice were infected with Plasmodium yoelii and administered metformin. Levels of parasitemia were reduced in treated mice compared with those in untreated mice, starting at ~2 weeks post-infection. The number of γδ T cells dramatically increased in the spleens of treated mice compared with that in untreated mice during the later phase of infection, while that of αβ T cells did not. The proportions of Vγ1+ and Vγ2+ γδ T cells increased, suggesting that activated cells were selectively expanded. However, these γδ T cells expressed inhibitory receptors and had severe defects in cytokine production, suggesting that they were in a state of exhaustion. Metformin was unable to rescue the cells from exhaustion at this stage. Depletion of γδ T cells with antibody treatment did not affect the reduction of parasitemia in metformin-treated mice, suggesting that the effect of metformin on the reduction of parasitemia was independent of γδ T cells.

Abstract
OBJECTIVE We analyzed acute ischemic stroke by thromboembolism in the early period after lung cancer surgery. METHODS A retrospective review of the clinical records of patients who underwent lung resection for primary lung cancer was performed. Patients who underwent lobectomy, bilobectomy, and pneumonectomy were included. The clinical characteristics of the patients, the incidence of atrial fibrillation (Af) after surgery, and the incidence of acute ischemic stroke were analyzed. The clinical courses of patients having acute ischemic stroke were also reviewed. RESULTS In 4 (0.6%) of 696 patients, acute ischemic stroke occurred in the early period during hospitalization after lung cancer surgery. Acute ischemic stroke occurred within 4 days in three cases and after 4 days in one case. The resection site of the lung was the left side in all cases, and there were three cases of left upper lobectomy and one case of left lower lobectomy. As for the two recent patients, thrombus removal was performed by a neurosurgeon, and both cases achieved successful recanalization. The time between symptom detection and recanalization was 205 and 170 min, respectively. One patient was cured without any residual effect of disease, and the other patient's hemiplegia resolved and aphasia improved. CONCLUSION Since cerebral infarction impairs the patient's quality of life, thrombus removal should be considered if possible.

Abstract
Background and objective: Phase difference enhanced imaging (PADRE), a new phase-related MRI technique, can enhance both paramagnetic and diamagnetic substances, and select which phases to be enhanced. Utilizing these characteristics, we developed color map of PADRE (Color PADRE), which enables simultaneous visualization of myelin-rich structures and veins. Our aim was to determine whether Color PADRE is sufficient to delineate the characteristics of non-gadolinium-enhancing T2-hyperintense regions related with metastatic tumors (MTs), diffuse astrocytomas (DAs) and glioblastomas (GBs), and whether it can contribute to the differentiation of MTs from GBs. Methods: Color PADRE images of 11 patients with MTs, nine with DAs and 17 with GBs were created by combining tissue-enhanced, vessel-enhanced and magnitude images of PADRE, and then retrospectively reviewed. First, predominant visibility of superficial white matter and deep medullary veins within non-gadolinium-enhancing T2-hyperintense regions were compared among the three groups. Then, the discriminatory power to differentiate MTs from GBs was assessed using receiver operating characteristic analysis. Results: The degree of visibility of superficial white matter was significantly better in MTs than in GBs (p = 0.017), better in GBs than in DAs (p = 0.014), and better in MTs than in DAs (p = 0.0021). On the contrary, the difference in the visibility of deep medullary veins was not significant (p = 0.065). The area under the receiver operating characteristic curve to discriminate MTs from GBs was 0.76 with a sensitivity of 80% and specificity of 64%. Conclusion: Visibility of superficial white matter on Color PADRE reflects inferred differences in the proportion of vasogenic edema and tumoral infiltration within non-gadolinium-enhancing T2-hyperintense regions of MTs, DAs and GBs. Evaluation of peritumoral areas on Color PADRE can help to distinguish MTs from GBs.

Abstract
Background Segmentectomy for lung cancer remains controversial because of the complexity of the procedure and concern about an increased recurrence rate. It is important to compare perioperative and oncological outcomes between segmentectomy and lobectomy. Methods From January 2007 to December 2016, 41 segmentectomies by video-assisted thoracic surgery (VATS) and 122 VATS lobectomies for 163 patients with clinical stage IA non-small cell lung cancer (NSCLC) were performed. Clinicopathological factors, including recurrence rate and survival rate, were compared. In order to reduce biases of outcomes, clinicopathological factors were used for propensity score matching (PSM). Then, 41 VATS segmentectomies and 41 lobectomies were selected and further analyzed. Results No significant differences were seen between the two groups in age, pulmonary function, comorbidity, operative time, blood loss, chest tube duration days, postoperative stay days, complications, histological type, and multiple primary rate. Smoking index resected number of nodes, tumor size, lymph node metastasis rate, and pathological stage were higher in the lobectomy group than in the segmentectomy group (P<0.05). In the lobectomy group, 16 patients (13.1%) had recurrence, and 2 patients (1.6%) died because of cancer progression. There were no significant differences in the recurrence rate and prognosis between the two groups. In addition, Cox regression analysis suggested that sex, lymph node metastasis, and pathology stage were associated with recurrence (P<0.05), but no factor was an independent prognostic factor. After PSM, the two groups had similar clinicopathological factors, and the type of operation still had no relationship with the recurrence rate or the death rate. Conclusions Perioperative and oncological outcomes of VATS segmentectomy are similar to those of VATS lobectomy for patients with clinical stage IA NSCLC. VATS segmentectomy can be considered one of the surgical procedures appropriate for patients with clinical stage IA NSCLC.

Abstract
Interferon regulatory factor 4 (IRF4) has critical roles in immune cell differentiation and function and is indispensable for clonal expansion and effector function in T cells. Here, we demonstrate that the AKT pathway is impaired in murine CD8+ T cells lacking IRF4. The expression of phosphatase and tensin homolog (PTEN), a negative regulator of the AKT pathway, was elevated in Irf4-/- CD8+ T cells. Inhibition of PTEN partially rescued downstream events, suggesting that PTEN constitutes a checkpoint in the IRF4-mediated regulation of cell signaling. Despite the clonal expansion defect, in the absence of IRF4, memory-like CD8+ T cells could be generated and maintained, although unable to expand in recall responses. The homeostatic proliferation of naïve Irf4-/- CD8+ T cells was impaired, whereas their number eventually reached a level similar to that of wild-type CD8+ T cells. Conversely, memory-like Irf4-/- CD8+ T cells underwent homeostatic proliferation in a manner similar to that of wild-type memory CD8+ T cells. These results suggest that IRF4 regulates the clonal expansion of CD8+ T cells at least in part via the AKT signaling pathway. Moreover, IRF4 regulates the homeostatic proliferation of naïve CD8+ T cells, whereas the maintenance of memory CD8+ T cells is IRF4-independent.

Abstract
Individuals living in malaria endemic areas become clinically immune after multiple re-infections over time and remain infected without apparent symptoms. However, it is unclear why a long period is required to gain clinical immunity to malaria, and how such immunity is maintained. Although malaria infection is reported to induce inhibition of immune responses, studies on asymptomatic individuals living in endemic regions of malaria are relatively scarce. We conducted a cross-sectional study of immune responses in asymptomatic school children aged 4-16years living in an area where Plasmodium falciparum and Schistosoma mansoni infections are co-endemic in Kenya. Peripheral blood mononuclear cells were subjected to flow cytometric analysis and cultured to determine proliferative responses and cytokine production. The proportions of cellular subsets in children positive for P. falciparum infection at the level of microscopy were comparable to the negative children, except for a reduction in central memory-phenotype CD8+ T cells and natural killer cells. In functional studies, the production of cytokines by peripheral blood mononuclear cells in response to P. falciparum crude antigens exhibited strong heterogeneity among children. In addition, production of IL-2 in response to anti-CD3 and anti-CD28 monoclonal antibodies was significantly reduced in P. falciparum-positive children as compared to -negative children, suggesting a state of unresponsiveness. These data suggest that the quality of T cell immune responses is heterogeneous among asymptomatic children living in the endemic region of P. falciparum, and that the responses are generally suppressed by active infection with Plasmodium parasites.

Abstract
Copper pyrithione (CuPT) is a biocide, used worldwide to prevent biofouling on submerged surfaces. In aquatic environments it rapidly degrades, however, one of the degradation products (HPT) is known to react with cupric ion back to its parent compound. Not much is known about the behavior and toxicity of CuPT and its degradation product HPT in different water systems. Hence, our aim was to investigate the ecotoxicity of CuPT, HPT as well as Cu2+ to the brine shrimp Artemia salina in natural seawater and organic matter-free artificial seawater. Moreover, in order to elucidate the influence of ionic strength of water on CuPT toxicity, tests were performed in water media with modified salinity. The results showed that CuPT was the most toxic to the exposed crustaceans in a seawater media with the highest salinity and with no organic matter content. HPT in a presence of cupric ion converted to CuPT, but the measured CuPT concentrations and the mortality of A. salina in natural water were lower than in artificial water. The toxicity of CuPT to A. salina was significantly influenced by the organic matter content, salinity, and proportions of constituent salts in water. In a combination with cupric ion, non-hazardous degradation product HPT exhibits increased toxicity due to its rapid transformation to its parent compound.

Abstract
[Purpose] This study aimed to understand the nutritional status of patients hospitalized
for long periods and the risk of physical therapy (PT) for such patients. [Subjects and
Methods] Participants were selected from patients who were hospitalized at a designated
medical long-term care sanatorium. The participants were divided into 5 groups (A–E)
depending on their mode of energy intake and ambulatory ability during PT. The serum
albumin level, energy intake, total daily energy expenditure, and total daily energy
expenditure per session of PT (EEPT) were evaluated for each group. [Results]
Protein-energy malnutrition was observed in 69.6% of the participants. No significant
association was identified between the serum albumin level and body mass index. Energy
intake was significantly higher in Groups D and E, whose energy intake was via ingestion,
than in Groups A and B, whose intake was via tube feeding. EEPT was highest in patients of
Group E who had gait independence different from the ability of those in groups A–D.
[Conclusion] The actual energy intake is lower with tube feeding than with ingestion. Risk
management and energy intake should be revisited in elderly patients who have been
hospitalized for long periods and subsequently obtain gait independence.

Abstract
PURPOSE Implantation of carmustine wafers (Gliadel) in vivo is accompanied by characteristic serial changes on MRI and CT, such as transient hyperintensity of the wafers on T1-weighted images (T1WIs) and considerable gas accumulation in surgical resection cavities. The purpose of this study was to evaluate intrinsic imaging changes to carmustine wafers in vitro. METHODS Three phantoms simulating a surgical resection cavity were constructed. Each contained either a carmustine wafer fixed with oxidized regenerated cellulose and fibrin sealant, an unfixed carmustine wafer, or a fixed polyethylene control disk, immersed in phosphate-buffered saline. Image acquisition of the phantoms was performed on MRI and CT until 182 days after construction. The radiological appearances of the object in each phantom were assessed by visual evaluation and quantification of the region of interest. The volume of gas around the objects at 24 h after constructing the phantoms was also measured. RESULTS The carmustine wafers showed low signal intensities on T1WIs and T2-weighted images (T2WIs), and high densities on CT images at 24 h. The signal intensities and CT densities gradually approximated those of saline over a period of months. However, the carmustine wafers never showed hyperintensity on T1WIs in vitro. The fixed carmustine wafer showed slower radiological changes, as compared to the unfixed wafer. The gas volume around the fixed carmustine wafer was greater than that around the fixed control disk. CONCLUSION Changes to the carmustine wafers probably reflected penetration of fluid inside and degradation of the hydrophobic matrix. Reported transient hyperintensity of wafers on T1WIs in vivo is regarded as the result of biological reactions, whereas the initial production of gas is considered as an intrinsic characteristic of wafers.

Abstract
Spontaneous regression of anterior mediastinal seminoma with normalization of β-human chorionic gonadotropin (β-hCG) levels shows good clinical outcome and sensitive to chemotherapy. Video-assisted thoracic surgery (VATS) is effective solution for definite diagnosis of anterior mediastinal. Apoptosis may be a reason of tumors’ spontaneous regression.
Introduction Although spontaneous regression (SR) of anterior mediastinal seminoma is very rare with normalization of β-human chorionic gonadotropin (β-hCG) level, video-assisted thoracic surgery (VATS) is the most effective solution for definite diagnosis of indeterminate anterior mediastinal masses. Diagnosis, therapeutic interventions, and outcomes A rare case of an asymptomatic 37-year-old man with an anterior mediastinal mass that was detected on a routine chest X-ray is presented. Computed tomography (CT) showed a large anterior mediastinal tumor with superior vena cava invasion and SR before VATS for definitive diagnosis. On pathology, the definitive diagnosis was seminoma. Microscopic examination showed abundant apoptotic cells within the tumor. Chemotherapy (bleomycin 30 mg/day, etoposide 200 mg/day, cisplatin 40 mg/day) was given to this patient, and the tumor showed high sensitivity. Conclusion Anterior mediastinal seminoma showing SR induced by spontaneous apoptosis of tumor cells may have good sensitivity to chemotherapy, and a good clinical outcome may be achieved in these patients. This case also highlights that VATS is the most effective solution for definite diagnosis of indeterminate anterior mediastinal masses.

Abstract
Summary Patients with Cushing’s syndrome and excess exogenous glucocorticoids have an increased risk for venous thromboembolism, as well as arterial thrombi. The patients are at high risk of thromboembolic events, especially during active disease and even in cases of remission and after surgery in Cushing’s syndrome and withdrawal state in glucocorticoid users. We present a case of Cushing’s syndrome caused by adrenocorticotropic hormone-secreting lung carcinoid tumor. Our patient developed acute mesenteric ischemia after video-assisted thoracoscopic surgery despite administration of sufficient glucocorticoid and thromboprophylaxis in the perioperative period. In addition, our patient developed hepatic infarction after surgical resection of the intestine. Then, the patient was supported by total parenteral nutrition. Our case report highlights the risk of microthrombi, which occurred in our patient after treatment of ectopic Cushing’s syndrome. Guidelines on thromboprophylaxis and/or antiplatelet therapy for Cushing’s syndrome are acutely needed. Learning points:

Abstract
The spleen is the major organ in which T cells are primed during infection with malaria parasites. However, little is known regarding the dynamics of the immune responses and their localization within the splenic tissue during malaria infection. We examined murine CD8+ T cell responses during infection with Plasmodium berghei using recombinant parasites expressing a model antigen ovalbumin (OVA) protein and compared the responses with those elicited by Listeria monocytogenes expressing the same antigen. OVA-specific CD8+ T cells were mainly activated in the white pulp of the spleen during malaria infection, as similarly observed during Listeria infection. However, the fates of these activated CD8+ T cells were distinct. During infection with malaria parasites, activated CD8+ T cells preferentially accumulated in the red pulp and/or marginal zone, where cytokine production of OVA-specific CD8+ T cells decreased, and the expression of multiple inhibitory receptors increased. These cells preferentially underwent apoptosis, suggesting that T cell exhaustion mainly occurred in the red pulp and/or marginal zone. However, during Listeria infection, OVA-specific CD8+ T cells only transiently expressed inhibitory receptors in the white pulp and maintained their ability to produce cytokines and become memory cells. These results highlighted the distinct fates of CD8+ T cells during infection with Plasmodium parasites and Listeria, and suggested that activation and exhaustion of specific CD8+ T cells occurred in distinct spleen compartments during infection with malaria parasites.

Abstract
A 66-year-old man diagnosed as dilated phase of hypertrophic cardiomyopathy (D-HCM) was pointed out an abnormal shadow on routine chest radiography. The patient had past medical history of hypertension, congestive heart failure and chronic obstructive pulmonary disease. The computed tomography showed a 3.8 cm-sized tumor in the left lower lobe of the lung, and histopathological examination revealed squamous cell carcinoma (cT2aN0-1M0, cStage I B-II A). Cardiosonography showed diffuse hypokinesis from basal to mid area, and ejection fraction was 36.3%. Sporadic ventricular premature contraction was seen by the Holter electrocardiogram. The patient underwent left lower lobectomy with node lymph node dissection (ND1b). The circulatory condition of the patient was stable during surgery. After surgery, careful management of electrolytes and fluid infusion, and the regular medication was started again on the next day of surgery.

Abstract
AIM We conducted a cohort study to elucidate paticipants' facilitative factors that may help to prevent cognitive decline. METHODS This study followed 100 participants (average age: 74.1 ± 5.8; 10 men, 90 women) for 3 years; participants had previously been part of the Taketoyo Project (n = 366) in 2007-2011. The end-point was defined as reduced cognitive function in elderly community residents participating in a preventive intervention for dementia. The presence or absence of reduced cognitive function at the end of the third year of intervention was the dependent variable, and all evaluation items were considered explanatory variables. After Fisher's exact test (P < 0.15), stepwise multiple logistic regression analysis (P < 0.05) was performed, and facilitative factors for prevention of cognitive decline were extracted. RESULTS Items with a significant adjusted odds ratio (OR) based on multiple logistic regression analysis were the three-word delayed recall test (OR: 0.330, 95% confidence interval (CI): 0.142-0.767; P < 0.05), word fluency (OR: 0.565, 95%CI: 0.359-0.891; P < 0.05), frequency of going out (OR: 2.790, 95%CI: 0.803-6.380; P < 0.05) and number of friends with whom they engaged in activities (OR:0.344, 95%CI: 0.127-0.932; P < 0.05). CONCLUSION Subjects who had maintained a certain level of cognitive function, engaged in activities with friends, and went out frequently at baseline were extracted. In other words, the results suggested that enhancement of social networks and leisure activities prompted by recreational centre participation had a positive effect on maintaining cognitive function. The results also suggest that to improve the effectiveness of preventive interventions for cognitive dysfunction, support for social factors and leisure activities, in addition to cognitive function, may improve the long-term effectiveness of maintaining cognitive function.

Abstract
A 61-year-old man visited a physician complaining of progressive chest pain and dyspnea. The chest radiography showed complete collapse of the right lung suggesting tension pneumothorax. The patient was transferred to our hospital. A small amount of the right pleural effusion was also seen in addition to pulmonary collapse on the chest radiography. Chest drainage was performed, and continuous air leakage was seen. At 2 hours later, air leakage was disappeared but the bloody effusion was noted. The chest radiography revealed massive effusion and the enhanced computed tomography showed active bleeding. The emergency surgery was conducted. The bleeding point was a ruptured vessel between the apical parietal pleura and the pulmonary bulla. Hemostasis and the resection of the bullae was performed. Careful observation after chest drainage is necessary to prepare unexpected hemothorax in case of tension pneumothorax with pleural effusion.

Abstract
[Purpose] Post-stroke astasia is an inability to stand without external support despite
having sufficient muscle strength. However, the dysfunction underlying astasia is unclear.
We tested the hypothesis that astasia is the result of an abnormal bias in vertical
perception, especially subjective postural vertical (SPV), mediated by somatosensory
inputs. [Subjects and Methods] A patient with a right posterolateral thalamus hemorrhage
had a tendency to fall toward the contralesional side during standing after 8 weeks of
treatment. SPV, standing duration, and physical function were evaluated before and after a
1 week standard rehabilitation baseline period, and after a 1 week intervention period,
where standing training requiring the patient to control his body orientation in reference
to somatosensory inputs from his ipsilateral upper limb was added. [Results] SPV was
biased toward the contralesional side before and after the 1 week baseline period.
However, SPV improved into the normal range and he could stand for a longer duration after
the intervention period. [Conclusion] This case suggests that abnormal SPV is one of the
functional mechanisms underlying astasia, and it indicates the effectiveness of standing
training with somatosensory information to improve abnormal SPV and postural
disorders.

Abstract
This study evaluates fat suppression of diffusion-weighted imaging (DWI) using section select gradient reversal (SSGR) technique in clinical images on 3 T breast MRI. A total of 20 patients with breast cancer were examined at a Philips Ingenia 3 T MRI. We acquired DWI with SPAIR, SSGR-SPAIR, STIR, and SSGR-STIR. We evaluated contrast between the fat region and lesion, the coefficient of variance (CV) of the fat region and the apparent diffusion coefficient (ADC) of normal breast tissue and lesion. The contrast between the fat region and lesion was improved with SSGR technique. The CV of the fattest region did not have any significant difference in SPAIR technique (p>0.05), but it was significantly decreased in the STIR technique using SSGR technique (p<0.05). Positive correlation was observed in ADC value between SPAIR and other fat suppression techniques (SSGR-SPAIR, STIR, SSGR-STIR). DWI using SSGR technique was suggested to be effective on 3 T breast MRI.

Abstract
BACKGROUND Severe dengue with severe plasma leakage (SD-SPL) is the most frequent of dengue severe form. Plasma biomarkers for early predictive diagnosis of SD-SPL are required in the primary clinics for the prevention of dengue death. METHODOLOGY Among 63 confirmed dengue pediatric patients recruited, hospital based longitudinal study detected six SD-SPL and ten dengue with warning sign (DWS). To identify the specific proteins increased or decreased in the SD-SPL plasma obtained 6-48 hours before the shock compared with the DWS, the isobaric tags for relative and absolute quantification (iTRAQ) technology was performed using four patients each group. Validation was undertaken in 6 SD-SPL and 10 DWS patients. PRINCIPAL FINDINGS Nineteen plasma proteins exhibited significantly different relative concentrations (p<0.05), with five over-expressed and fourteen under-expressed in SD-SPL compared with DWS. The individual protein was classified to either blood coagulation, vascular regulation, cellular transport-related processes or immune response. The immunoblot quantification showed angiotensinogen and antithrombin III significantly increased in SD-SPL whole plasma of early stage compared with DWS subjects. Even using this small number of samples, antithrombin III predicted SD-SPL before shock occurrence with accuracy. CONCLUSION Proteins identified here may serve as candidate predictive markers to diagnose SD-SPL for timely clinical management. Since the number of subjects are small, so further studies are needed to confirm all these biomarkers.

Abstract
BACKGROUND Diabetes mellitus (DM) is a major risk factor for periodontal disease and affects various cellular functions. Periodontal ligament stem cells (PDLSCs) play an important role in periodontal tissue regeneration; however, the effect of hyperglycemia on PDLSCs is unclear. The aim of this study is to investigate whether hyperglycemia affects periodontal tissue regeneration, using human PDLSCs and high-glucose medium as a model of DM. METHODS PDLSCs were obtained from healthy adult human mandibular third molars. Cell proliferation, osteoblastic differentiation, and proinflammatory cytokine expression were investigated by culturing PDLSCs in media supplemented with four different glucose concentrations representative of control patients (5.5 mM), patients with postprandial or controlled DM (8.0 mM), and patients with uncontrolled DM (12.0 and 24.0 mM). The molecular effects of hyperglycemia on PDLSC physiology were examined with a focus on the nuclear factor (NF)-(κB signaling pathway. The involvement of NF-κB was investigated with a specific NF-κB inhibitor in PDLSCs under hyperglycemic conditions. RESULTS High glucose levels inhibited PDLSC proliferation and differentiation into osteoblasts but induced NF-κB activation and subsequent interleukin (IL)-6 and IL-8 expression. Treatment with an NF-κB inhibitor rescued the defects in cell proliferation and osteoblastic differentiation and inhibited the IL-6 expression caused by the high-glucose environment. CONCLUSION The results of this study demonstrate that hyperglycemia inhibits human PDLSC proliferation and osteoblastic differentiation.
