Abstract
BACKGROUND AND PURPOSE Obtaining information on invisible vasculature distal to the occlusion site helps to deploy a stent retriever safely during mechanical thrombectomy for large-vessel occlusion. It is essential to reduce the amount of contrast used for detecting the vessels distal to the occlusion site because acute ischemic stroke patients tend to have chronic kidney disease and patients with severe chronic kidney disease are at an increased risk of contrast-associated acute kidney injury. We assessed whether vessels distal to the occlusion site during acute ischemic stroke with large-vessel occlusion could be visualized on angiographic images using flat panel detector CT acquired following intra-arterial diluted contrast injection, compared with MRA findings. MATERIALS AND METHODS Between May 2019 and January 2020, we enrolled 28 consecutive patients with large-vessel occlusions of the anterior circulation eligible for mechanical thrombectomy following MR imaging. The patients underwent CBV imaging using flat panel detector CT with an intra-arterial diluted contrast injection instead of intravenous injection. Flat panel detector CT angiographic images reconstructed from the same dataset were evaluated for image quality, collateral status of the MCA territory, and visualization of the vessels distal to the occlusion site. These findings were compared with MRA findings. RESULTS Twenty-two patients were retrospectively examined. Flat panel detector CT angiographic image quality in 20 patients (91%) was excellent or good. The distal portion of the occluded vessel segment was visualized in 14 patients (70%), while the proximal portion of the segment adjacent to the occluded vessel in 3 (15%) was visualized. No visualization was observed in only 1 patient (5%) with no collateral supply. Flat panel detector CT angiographic images were shown to evaluate vessels distal to the occlusion site more accurately than MRA. CONCLUSIONS In acute ischemic stroke with large-vessel occlusion, flat panel detector CT angiographic images could successfully visualize vessels distal to the occlusion site with a small amount of contrast material.

Abstract
BACKGROUND AND OBJECTIVES To treat organ transplant patients with mycobacterial infection, physicians need to pay attention to interaction between drugs used against mycobacteria and immunosuppressants. The purpose of this report is to describe the clinical features of and treatment for mycobacterial infection in lung transplant (LTx) recipients. METHODS To investigate the incidence, treatment, and outcome for mycobacterial infection, we retrospectively reviewed 100 LTx recipients in our program since 2000. RESULTS Four recipients (4.0%) developed mycobacterial infection. Three recipients took tacrolimus, and 1 received cyclosporine with mycophenolate mofetil and a steroid for immunosuppression. Tuberculosis (TB) was isolated from 2 recipients, and non-tuberculous mycobacteriosis (NTM) was detected in the other 2. We treated the patients with levofloxacin + isoniazid + pyrazinamide + ethambutol (EB) for TB and clarithromycin (CLM) + EB for NTM to avoid interaction of calcineurin inhibitors (CNI: 8-10 ng/mL in trough level) with rifampicin (RFP). In treating the patients with NTM, we were able to maintain an adequate blood concentration of CNI by decreasing the dosage from one-half to one-quarter. All mycobacterial infections were controlled with treatment. In 1 patient with chronic obstructive pulmonary disease (COPD) infected with TB in the native lung, the forced expiratory volume in 1 second (FEV1) unexpectedly increased from 1890 mL before infection to 2320 mL possibly due to organization of the native lung. CONCLUSIONS We were able to manage the mycobacterial infections using drugs other than RFP without any cases of acute rejection under adequate immunosuppression. Organization of the native lung with TB infection unexpectedly resulted in improvement of FEV1 in a COPD patient.

Abstract
AIMS To assess the predictive ability of a genetic risk score for the incidence of Type 2 diabetes in a general Japanese population. METHODS This prospective case-control study, nested within a Japan Public Health Centre-based prospective study, included 466 participants with incident Type 2 diabetes over a 5-year period (cases) and 1361 control participants, as well as 1463 participants with existing diabetes and 1463 control participants. Eleven susceptibility single nucleotide polymorphisms, identified through genome-wide association studies and replicated in Japanese populations, were analysed. RESULTS Most single nucleotide polymorphism loci showed directionally consistent associations with diabetes. From the combined samples, one single nucleotide polymorphism (rs2206734 at CDKAL1) reached a genome-wide significance level (odds ratio 1.28, 95% CI 1.18-1.40; P = 1.8 × 10-8 ). Three single nucleotide polymorphisms (rs2206734 in CDKAL1, rs2383208 in CDKN2A/B, and rs2237892 in KCNQ1) were nominally significantly associated with incident diabetes. Compared with the lowest quintile of the total number of risk alleles, the highest quintile had a higher odds of incident diabetes (odds ratio 2.34, 95% CI 1.59-3.46) after adjusting for conventional risk factors such as age, sex and BMI. The addition to the conventional risk factor-based model of a genetic risk score using the 11 single nucleotide polymorphisms significantly improved predictive performance; the c-statistic increased by 0.021, net reclassification improved by 6.2%, and integrated discrimination improved by 0.003. CONCLUSIONS Our prospective findings suggest that the addition of a genetic risk score may provide modest but significant incremental predictive performance beyond that of the conventional risk factor-based model without biochemical markers.

Abstract
OBJECTIVE Masticatory muscle tendon-aponeurosis hyperplasia, which is associated with limited mouth opening, progresses very slowly from adolescence. The prevalence rates of this disease are higher among women than among men, suggesting oestrogen involvement. As parafunctional habits are frequently observed, mechanical stress is likely involved in the pathogenesis and advancement of this disease. To elucidate the pathological condition, we examined the effect of oestrogen on tenocyte function and the relationship between mechanical stress and crystallin beta A4 (Cryba4), using murine TT-D6 tenocytes. MATERIALS AND METHODS Cell proliferation assays, RT-PCR, real-time RT-PCR, Western blot analysis and mechanical loading experiments were performed. RESULTS The physiological dose of oestrogen increased the levels of scleraxis and tenomodulin in TT-D6 tenocytes. In contrast, forced expression of Cryba4 inhibited scleraxis expression in these cells. Surprisingly, oestrogen significantly promoted cell differentiation in the Cryba4-overexpressing TT-D6 tenocytes. Moreover, tensile force induced Cryba4 expression in these tendon cells. CONCLUSION Oestrogen and Cryba4 may be associated with the progression of masticatory muscle tendon-aponeurosis hyperplasia.

Cytotoxicity of Natural Killer Cells Activated Through NKG2D Contributes to the Development of Bronchiolitis Obliterans in a Murine Heterotopic Tracheal Transplant Model. Am J Transplant 2017; 17:2338-2349.

Abstract
Bronchiolitis obliterans after lung transplantation is a major cause of postoperative mortality in which T cell-mediated immunity is known to play an important role. However, the exact contribution of natural killer (NK) cells, which have functions similar to CD8+ T cells, has not been defined. Here, we assessed the role of NK cells in murine bronchiolitis obliterans through heterotopic tracheal transplantations and found a greater percentage of NK cells in allografts than in isografts. Depletion of NK cells using an anti-NK1.1 antibody attenuated bronchiolitis obliterans in transplant recipients compared with controls. In terms of NK cell effector functions, an improvement in bronchiolitis obliterans was observed in perforin-KO recipient mice compared to wild type (WT). Furthermore, we found upregulation of NKG2D-ligand in allografts and demonstrated the significance of this using grafts expressing Rae-1, a murine NKG2D-ligand, which induced severe bronchiolitis obliterans in WT and Rag-1 KO recipients. This effect was ameliorated by injection of anti-NKG2D blocking antibody. Together, these results suggest that cytotoxicity resulting from activation of NK cells through NKG2D leads to the development of murine bronchiolitis obliterans.

Abstract
Clamshell incision is a standard approach for bilateral lung transplantation, providing a good operative field; however, once wide dehiscence occurs, its management is sometimes difficult because of intense immunosuppression and malnutrition of the recipient. A 22-year-old man with idiopathic pulmonary arterial hypertension underwent cadaveric bilateral lung transplantation through a clamshell incision using standard cardiopulmonary bypass. He developed wound dehiscence on postoperative day (POD) 20 that resulted in exposure of the bilateral fifth ribs and open pneumothorax. Considering the extreme malnutrition and emaciation of the recipient, we avoided initial closure of the dehiscence. After the debridement of necrotic tissue, negative pressure wound therapy was initiated on POD 25 and was continued for approximately 6 months with trafermin spray application. Eventually, the wound, including the fifth ribs, was completely covered with granulation tissue except for the wire tying the sternum. On POD 217, the patient underwent removal of the sternal wire followed by split-thickness skin grafting. His wound was successfully closed and he was discharged without activity limitation on POD 265.

Abstract
AIMS To evaluate the effect of multifaceted interventions using the Achievable Benchmark of Care (ABC) method for improving the technical quality of diabetes care in primary care settings. METHODS We conducted a 1-year cluster randomized controlled trial in 22 regions divided into an intervention group (IG) or control group (CG). Physicians in the IG received a monthly report of their care quality, with the top 10% quality of diabetes care scores for all physicians being the achievable benchmark. The change in quality-of-care scores between the IG and CG during follow-up was analysed using a generalized linear model considering clustering. RESULTS A total of 2199 patients were included. Their mean (sd) age was 56.5 ± 5.9 years and the mean (sd) HbA1c level was 56.4 ± 13.3 mmol/mol (7.4 ± 1.2%). The quality-of-care score in the CG changed from 50.2%-point at baseline to 51%-point at 12 months, whereas the IG score changed from 49.9%-point to 69.6%-point, with statistically significant differences between the two groups during follow-up [the effect of intervention was 19.0%-point (95% confidence interval 16.7%- to 21.3%-point; P < 0.001)]. CONCLUSIONS Multifaceted intervention, measuring quality-of-care indicators and providing feedback regarding the quality of diabetes care to physicians with ABC, was effective for improving the technical quality of care in patients with Type 2 diabetes in primary care settings.

Abstract
Autism and Alzheimer's disease (AD) are, respectively, neurodevelopmental and degenerative diseases with an increasing epidemiological burden. The AD-associated amyloid-β precursor protein-α has been shown to be elevated in severe autism, leading to the 'anabolic hypothesis' of its etiology. Here we performed a focused microarray analysis of genes belonging to NOTCH and WNT signaling cascades, as well as genes related to AD and apoptosis pathways in cerebellar samples from autistic individuals, to provide further evidence for pathological relevance of these cascades for autism. By using the limma package from R and false discovery rate, we demonstrated that 31% (116 out of 374) of the genes belonging to these pathways displayed significant changes in expression (corrected P-values <0.05), with mitochondria-related genes being the most downregulated. We also found upregulation of GRIN1, the channel-forming subunit of NMDA glutamate receptors, and MAP3K1, known activator of the JNK and ERK pathways with anti-apoptotic effect. Expression of PSEN2 (presinilin 2) and APBB1 (or F65) were significantly lower when compared with control samples. Based on these results, we propose a model of NMDA glutamate receptor-mediated ERK activation of α-secretase activity and mitochondrial adaptation to apoptosis that may explain the early brain overgrowth and disruption of synaptic plasticity and connectome in autism. Finally, systems pharmacology analyses of the model that integrates all these genes together (NOWADA) highlighted magnesium (Mg(2+)) and rapamycin as most efficient drugs to target this network model in silico. Their potential therapeutic application, in the context of autism, is therefore discussed.

Abstract
Background: Motor three-wheel drivers provide an important means of transportation in Sri Lanka, comprising 15% of motorized road vehicles. Although three-wheel driving is a widespread occupation for Sri Lankan men, little is known about their general health or risk factors.Objectives: This paper investigates chronic illnesses and risk factors for such illnesses in a sample of 33 three-wheel drivers in Galle, Sri Lanka.Methods: A qualitative investigation was conducted between June and August 2012. 20 three-wheel drivers participated in 60-minute semi-structured interviews, and 13 participated in semi- structured focus groups related to their work-related health concerns.Results: Illness reported included musculoskeletal pain, hypercholesteremia, hypertension, and diabetes. Participants identified work-related stress and substance abuse as risk factors.Conclusions: Participants described a cycle of work related stress, substance use, and chronic illness. Community-based education on the risks of substance use and alternative means of coping may be an effective intervention for these workers. DOI: http://dx.doi.org/10.3126/ijosh.v3i2.7662

Abstract
AIMS/HYPOTHESIS Insufficient insulin secretion and reduced pancreatic beta cell mass are hallmarks of type 2 diabetes. Here, we focused on a family of serine-threonine kinases known as homeodomain-interacting protein kinases (HIPKs). HIPKs are implicated in the modulation of Wnt signalling, which plays a crucial role in transcriptional activity, and in pancreas development and maintenance. The aim of the present study was to characterise the role of HIPKs in glucose metabolism. METHODS We used RNA interference to characterise the role of HIPKs in regulating insulin secretion and transcription activity. We conducted RT-PCR and western blot analyses to analyse the expression and abundance of HIPK genes and proteins in the islets of high-fat diet-fed mice. Glucose-induced insulin secretion and beta cell proliferation were measured in islets from Hipk3 ( -/- ) mice, which have impaired glucose tolerance owing to an insulin secretion deficiency. The abundance of pancreatic duodenal homeobox (PDX)-1 and glycogen synthase kinase (GSK)-3β phosphorylation in Hipk3 ( -/- ) islets was determined by immunohistology and western blot analyses. RESULTS We found that HIPKs regulate insulin secretion and transcription activity. Hipk3 expression was most significantly increased in the islets of high-fat diet-fed mice. Furthermore, glucose-induced insulin secretion and beta cell proliferation were decreased in the islets of Hipk3 ( -/- ) mice. Levels of PDX1 and GSK-3β phosphorylation were significantly decreased in Hipk3 ( -/- ) islets. CONCLUSIONS/INTERPRETATION Depletion of HIPK3 impairs insulin secretion and glucose tolerance. Decreased levels of HIPK3 may play a substantial role in the pathogenesis of type 2 diabetes.

Abstract
BACKGROUND/OBJECTIVE Dietary patterns in Western populations have been linked to type 2 diabetes, but the association of distinctive dietary patterns of Japanese population remains unclear. We prospectively investigated the association between dietary patterns and risk of developing type 2 diabetes among Japanese adults. SUBJECTS/METHODS Participants were 27, 816 men and 36,889 women aged 45-74 years who participated in the second survey of the Japan Public Health Center-based prospective study and had no history of diabetes. Dietary patterns were derived by using principal component analysis of the consumption of 134 food and beverage items ascertained by a food frequency questionnaire. Odds ratios of self-reported physician-diagnosed type 2 diabetes over 5 year were estimated using logistic regression analysis. RESULTS A total of 1194 new cases (692 men and 502 women) of type 2 diabetes were self-reported. We identified three dietary patterns: prudent, westernized and traditional Japanese patterns. Any dietary pattern was not significantly associated with type 2 diabetes risk after adjustment for covariates in both men and women. The multivariate-adjusted odds ratios (95% confidence interval) for type 2 diabetes for the highest versus lowest quartile of each dietary pattern score in men and women, respectively, were 0.93 (0.74-1.16) and 0.90 (0.69-1.16) for the prudent pattern, 1.15 (0.90-1.46) and 0.81 (0.61-1.08) for the westernized pattern, and 0.97 (0.74-1.27) and 0.87 (0.66-1.15) for the traditional pattern. CONCLUSIONS Although a small protective effect of the prudent dietary pattern cannot be excluded, dietary patterns may not be appreciably associated with type 2 diabetes risk in Japanese.

Abstract
Pulmonary metastasectomy is indicated for selected patients with metastatic colorectal cancer. A 43-year-old woman presented with solitary pulmonary metastasis from descending colon cancer and pulmonary metastasectomy was performed because of absence of any other active metastasis as well as normal serum carcinoembryonic antigen value. However, she died due to early development of nodal and bone metastases within 6 months after thoracotomy. The presence of circulating tumor cells (CTCs) in the peripheral blood (6 CTCs/7.5 ml) was the only factor to predict such a poor prognosis, suggesting that the CTC test is useful in selecting patients for pulmonary metastasectomy.

Abstract
We investigated whether or not preoperative intraluminal brachytherapy (IBT) contributes to a prolongation of the survival after resection of rectal carcinoma. Eighty-five patients with middle and lower rectal carcinoma with penetration into or through the rectal wall were treated with preoperative IBT (30 Gy) and radical resection. The patients were divided into the major effect group (n=59, proportion of remaining viable cells less than 25% of the background stroma) and the minor effect group (n=26, proportion of viable cells over 25%). The major effect group had more down-staged tumors, and a lower rate of positive nodes. Local recurrence rate, distant recurrence rate, and survival rate of the major effect group were 9% (31% in the minor effect group), 15% (55% in minor group) and 74% (36% in minor group), respectively (all parameters: p<0.05). Multivariate analysis indicated that nodal involvement, tumor depth, and proportion of viable cells were the prognostic factors. Preoperative IBT affected not only the tumor morphology but also the prognosis. Our criterion of the proportion of residual viable cells was significantly correlated to the patients' survival. The analyses revealed the positive effects of IBT on the prognosis of rectal cancer.

Abstract
AIMS Using the HbA(1c) level to define diabetes has several advantages and these advantages also apply to define a high-risk group. However, the risk of diabetes increases as HbA(1c) increases and a certain degree of arbitrariness in the cut-off for the high risk group is unavoidable. The aim of this study was to determine the HbA(1c) cut-off for defining a high-risk group that corresponds to the fasting plasma glucose cut-off by comparing the risk of diabetes against the fasting plasma glucose and HbA(1c) levels in the Japanese population. METHODS A retrospective cohort study was conducted using data from annual health examinations performed in Omiya city. A total of 11,271 subjects between the ages of 40 and 79 years without diabetes at baseline were followed for up to 7 years. According to the new diagnostic criteria, diabetes was defined as an fasting plasma glucose level ≥ 7 mmol/l or an HbA(1c) level ≥ 48 mmol/mol (≥ 6.5%) or a self-report. The HbA(1c) cut-off corresponding to the fasting plasma glucose cut-off was determined using the incidence, hazard ratio, and a receiver operating characteristic analysis. RESULTS Eight hundred and sixty subjects developed diabetes. The incidence, hazard ratio, and receiver operating characteristic analysis all indicated that an HbA(1c) cut-off of 39 mmol/mol (5.7%) corresponded to an fasting plasma glucose level of 5.6 mmol/l. CONCLUSIONS Our results suggested that the HbA(1c) cut-off for high-risk of diabetes should be 39 mmol/mol (5.7%), consistent with the American Diabetes Association recommendation. Further research is needed to determine whether our results are applicable to other populations.

Abstract
OBJECTIVE To examine the relationship between short sleep duration and body mass index (BMI), waist circumference (WC), visceral fat area (VFA) and subcutaneous fat area (SFA) among a working population in Japan. DESIGN Health-center-based, cross-sectional study. SUBJECTS The study subjects included 5400 men and 642 women aged 30 to 75 years who underwent an abdominal computed tomography (CT) scanning examination in a comprehensive health checkup. MEASUREMENTS Height and weight were measured, and BMI was calculated. WC, VFA and SFA were measured using a CT scanner. Sleep duration was self-reported. Analysis of covariance was used to estimate adjusted means of BMI, WC, VFA and SFA across categories of sleep duration with adjustments for potential confounders. Trend of the association was assessed using multiple linear regression analysis. RESULTS In men, the mean values of BMI, WC and SFA decreased with increasing sleep duration after adjustment for age, physical activity, smoking and drinking (P-value for trend <0.001). Additional adjustment for physical illnesses did not attenuate the explanatory power of the models (P-value for trend <0.001). In addition, the association between sleep duration and SFA did not change after controlling for VFA (P-value for trend <0.001). The mean values of SFA for subjects sleeping '<5 h', '5 to <6 h', '6 to <7 h' and '7 h' per day were 145.8±67.4 cm(2), 138.7±61.5 cm(2), 134.7±60.4 cm(2) and 132.5±49.2 cm(2), respectively. Sleep duration was not appreciably associated with VFA. In women, no significant association was detected in any models. CONCLUSION Shorter sleep duration is associated with higher BMI, WC and SFA in men. Further research is needed to explicate the biological mechanisms behind these relationships and to see whether interventions addressing inadequate sleep could treat or prevent obesity by taking gender differences into consideration.

Abstract
OBJECTIVE Apoptosis of chondrocytes in articular cartilage has been observed in rheumatoid arthritis patients. However, molecules involved in such chondrocyte apoptosis in arthritic joints have not been fully understood. We previously observed that apoptosis of chondrocytes is enhanced in a murine arthritis model induced by injection with anti-type II collagen antibodies and lipopolysaccharide (mAbs/LPS), and osteopontin (OPN) deficiency suppresses chondrocyte apoptosis in this arthritis model in vivo. To understand how OPN deficiency renders resistance against chondrocyte apoptosis, we examined the cellular basis for this protection. DESIGN Chondrocytes were prepared from wild-type and OPN-deficient mouse ribs, and tumor necrosis factor (TNF)-α-induced cell death was examined based on lactate dehydrogenase (LDH) release assay and TUNEL assay. RESULTS TNF-α treatment induced LDH release in wild-type chondrocytes, while OPN deficiency suppressed such LDH release in the cultures of these cells. TNF-α-induced increase in the number of TUNEL-positive cells was observed in wild-type chondrocytes, while OPN deficiency in chondrocytes suppressed the TNF-α induction of TUNEL-positive cells. OPN deficiency suppressed TNF-α-induced increase in caspase-3 activity in chondrocytes in culture. Furthermore, OPN overexpression in chondrocytes enhanced TNF-α-induced apoptosis. CONCLUSION These results indicated that the presence of OPN in chondrocytes is involved in the susceptibility of these cells to TNF-α-induced apoptosis.

Abstract
The patient was a 68 year-old woman who had a history of treatment of pulmonary tuberculosis 35 years ago. She has experienced dyspnea and hemosputa since several years ago and has been followed up as having chronic empyema. She was admitted to our hospital due to recent exacerbation of symptoms. X-ray films and computed tomography scans of the chest showed the right thoracic cavity to be totally filled with a mass and the shift of mediastinum to the left side. After several days from admission, she needed mechanical ventilation support due to dyspnea exacerbation. Emergency decortication with right pneumonectomy through median sternotomy with anterolateral incision was performed. Postoperative course was uneventful. Pathlogical diagnosis was chronic expanding hematoma.

Abstract
Secondary spontaneous pneumothorax (SSP) such as lymphangioleiomyomatosis (LAM), bronchiolitis obliterans (BO) is intractable or repeated the recurrence of pneumothorax. The most effective chemical pleurodesis for intractable pneumothorax is talc poudrage and so on that is associated with a reduction in the rate of pneumothorax recurrence. However, severe and broad pleural adhesion due to the pleural interventional procedures sometimes cause serious bleeding when the patients undergo lung transplantation. We must be considered for new approaches to these intractable secondary pneumothoraces which replaced traditional conservative and surgical approaches. We had proposed new 2 approaches of total pleural covering (TPC) and awake surgical intervention (ASI) for intractable pneumothorax. We applied the TPC modified with coverage of air leak points with polyglycolic acid (PGA) sheet to 5 patients with intractable bilateral pneumothorax to reduce the risk of excessive bleeding by chemical pleurodesis in lung transplantation. The bilateral pneumothorax was well controlled, and no recurrence has been observed. TPC is reliable procedure for management intractable bilateral SSP. For 12 high-risk patients with other underling pulmonary diseases on general poor conditions, a surgical intervention was performed in awake condition. The air leaks were stopped in 11 cases except for 1 case. The recurrence of pneumothorax after surgery was 2 cases. ASI for intractable secondary pneumothorax can be applicable to selected patients with deteriorated general condition.

Abstract
AbstractWe have performed molecular-dynamics (MD) simulations of hydrogenated amorphous silicon (a-Si:H) thin-film growth using realistic many-body semiclassical potentials developed to describe Si-H interactions. In our MD model, it was assumed that SiH3, SiH2 and the H radicals are main precursors for the thin-film growth. In MD simulations of a-Si:H thin-film growth by many significant precursor SiH3 radicals, we have evaluated average radical migration distances, defect ratios, hydrogen contents, and film growth rates as a function of different incident radical energies to know the effect of the radical energization on the properties. As a result of the comparison between the numerical and experimental results, it was observed that the agreement is fairly good, and that an increase of radical migration distance due to the radical energization is effective on a- Si:H thin-film growth with a low defect.

Abstract
Surgical approach is one of the most crucial aspects in the treatment of superior sulcus tumor (SST). Posterior approach as described by Paulson and coworkers is appropriate for the resection of SST invading posterior part of the 1st rib and the vertebrae, whereas anterior approaches as described by Masaoka, Dartevelle, Grunenwald, or Rusca are suitable for resection of SST involving subclavian vessels. We present 2 cases of SST who underwent complete resection through the posterior approach and a modified hemi-clamshell approach, respectively. We also discuss the surgical approaches for SST with referring to literatures.

Abstract
AIMS/HYPOTHESIS Calcium and vitamin D have been implicated in the development of type 2 diabetes, but epidemiological evidence is limited. We examined prospectively the relation of calcium and vitamin D intake to type 2 diabetes risk in a Japanese cohort. METHODS Participants were 59,796 middle-aged and older men and women, who participated in the Japan Public Health Center-based Prospective Study and had no history of type 2 diabetes or other serious diseases. Dietary intake of calcium and vitamin D were estimated using a validated food frequency questionnaire. Logistic regression was used to assess the association between intake of these nutrients and self-reported newly diagnosed type 2 diabetes. RESULTS During a 5 year follow-up, 1,114 cases of type 2 diabetes were documented. Overall, calcium intake was not associated with a significantly lower risk of type 2 diabetes; the multivariable odds ratio for the highest vs lowest quartiles was 0.93 (95% CI 0.71-1.22) in men and 0.76 (95% CI 0.56-1.03) in women. However, among participants with a higher vitamin D intake, calcium intake was inversely associated with diabetes risk; the odds ratio for the highest vs lowest intake categories was 0.62 (95% CI 0.41-0.94) in men and 0.59 (95% CI 0.38-0.91) in women. Dairy food intake was significantly associated with a lower risk of type 2 diabetes in women only. CONCLUSIONS/INTERPRETATION Calcium and vitamin D may not be independently associated with type 2 diabetes risk. Our finding suggesting a joint action of these nutrients against type 2 diabetes warrants further investigation.

Abstract
Following any type of brain injury such as lesion, stroke, and tumor/cancer invasion, microglia are rapidly activated and recruited to the site of injury. Microglia is the main immune effector cell population of the central nervous system and control immune cell recruitment. However, the molecular mechanism of brain metastasis and interaction between neuron-glia-tumor cells are poorly understood. Therefore, we established an animal model for brain metastasis using human lung cancer-derived cells (HARA-B) in nude mice. Accumulation of activated microglia was observed around tumor cells depending on the size of metastatic foci and the area of the brain. In vitro study, conditioned medium from primary cultured mouse microglia inhibited the proliferation of tumor cells, while tumor cell-conditioned medium inhibited the proliferation of primary cultured neurons from mouse cortex. Though the responsible factors released from microglia and tumor cells are still under investigation, these studies will contribute to understand the mechanism of cell-cell interaction in the brain and possible therapeutic target for brain metastasis.

Abstract
Male sex hormones play a critical role in regulation of bone metabolism. In male mice lacking androgen receptor (AR), osteopenia and high turnover state in bone remodeling have been reported. However, androgen receptor's role in disuse-induced osteopenia is not known. Therefore, we examined the effects of AR deficiency on unloading-induced bone loss. Wild type or androgen receptor deficient mice (ARKO) were subjected to hind limb unloading (HU) or normal housing (Control). The groups of mice were as follows; wild type control mice (Group WT-Cont), ARKO control mice (Group ARKO-Cont), wild type HU mice (Group WT-HU), and ARKO-HU mice (Group ARKO-HU). HU reduced cancellous bone mass in ARKO (ARKO-HU) by about 70% compared to ARKO-Cont and this reduction rate was over two-fold more than that of wild type (WT-HU) (reduction by less than 30% compared to WT-Cont). Combination of ARKO and HU (ARKO-HU) resulted in the least levels of cortical bone mass and bone mineral density among the four groups. ARKO-HU group indicated the highest levels of systemic bone resorption marker, deoxypyridinoline. Osteoclast development levels in the cultures in ARKO-HU derived bone marrow cells were the highest among the four groups. These data suggest that combination of androgen receptor deficiency and hind limb unloading results in exacerbation of disuse-induced osteopenia due to the enhanced levels of bone resorption.
