Lemon Polyphenols Suppress Diet-induced Obesity by Up-Regulation of mRNA Levels of the Enzymes Involved in β-Oxidation in Mouse White Adipose Tissue

The aim of this study was to investigate the effect of dietary lemon polyphenols on high-fat diet-induced obesity in mice, and on the regulation of the expression of the genes involved in lipid metabolism to elucidate the mechanisms. Mice were divided into three groups and fed either a low fat diet (LF) or a high fat diet (HF) or a high fat diet supplemented with 0.5% w/w lemon polyphenols (LP) extracted from lemon peel for 12 weeks. Body weight gain, fat pad accumulation, the development of hyperlipidemia, hyperglycemia, and insulin resistance were significantly suppressed by lemon polyphenols. Supplementation with lemon polyphenols also significantly up-regulated the mRNA level of the peroxisome proliferator activated receptor-α (PPARα) compared to the LF and HF groups in the liver. Furthermore, the mRNA level of acyl-CoA oxidase (ACO) was up-regulated in the LP group compared to the LF group, but not HF group in the liver, and was also significantly increased in the epididymal white adipose tissue. Thus, feeding with lemon polyphenols suppressed body weight gain and body fat accumulation by increasing peroxisomal β-oxidation through up-regulation of the mRNA level of ACO in the liver and white adipose tissue, which was likely mediated via up-regulation of the mRNA levels of PPARα

The development of a zero-dimensional collisional-radiative model for interpreting plasma emission in low temperature divertor plasmas in tokamaks

Collisional-radiative models are commonly used to analyse atomic and molecular processes in low temperature plasmas by determining the distribution functions of excited states as functions of various plasma parameters. This paper outlines the improvements to a zero-dimensional collisional-radiative model, developed at Keio University, for purposes relevant to the analysis of emission measurements in low temperature hydrogen plasmas. The extension of this 0D model centres on the inclusion of additional molecular species and reactions, a calculation of emission intensity in order to directly compare with experimental work, and the addition of a simple wall model to allow for a deeper understanding of recycling of atoms and molecules in low temperature plasmas close to plasma facing components in fusion machines. Results from the improved model are then compared with both an existing CR model for benchmarking and experimental emission spectroscopy data from an inductively-coupled plasma device at the University of Liverpool. These results show how the developments to the model have increased the relevance to experimental plasmas, such as those in the power exhaust regions of fusion machines, with the ratio of the Hβ/Hα line intensities outputted from the improved CR model mirroring more closely the emission measured experimentally in the ICP device

Peptide TNIIIA2 Derived from Tenascin-C Contributes to Malignant Progression in Colitis-Associated Colorectal Cancer via β1-Integrin Activation in Fibroblasts

Inflammatory bowel diseases increase the risk of colorectal cancer and colitis-associated colorectal cancer (CAC). Tenascin-C, a matricellular protein, is highly expressed in inflammatory bowel diseases, especially colorectal cancer. However, the role of tenascin-C in the development of CAC is not yet fully understood. We previously showed that a peptide derived from tenascin-C, peptide TNIIIA2, induces potent and sustained activation of β1-integrin. Moreover, we recently reported that peptide TNIIIA2 promotes invasion and metastasis in colon cancer cells. Here, we show the pathological relevance of TNIIIA2-related functional site for the development of CAC. First, expression of the TNIIIA2-containing TNC peptides/fragments was detected in dysplastic lesions of an azoxymethane/dextran sodium sulfate (AOM/DSS) mouse model. In vitro experiments demonstrated that conditioned medium from peptide TNIIIA2-stimulated human WI-38 fibroblasts induced malignant transformation in preneoplastic epithelial HaCaT cells. Indeed, these pro-proliferative effects stimulated by peptide TNIIIA2 were abrogated by peptide FNIII14, which has the ability to inactivate β1-integrin. Importantly, peptide FNIII14 was capable of suppressing polyp formation in the AOM/DSS model. Therefore, tenascin-C-derived peptide TNIIIA2 may contribute to the formation of CAC via activation of stromal fibroblasts based on β1-integrin activation. Peptide FNIII14 could represent a potential prophylactic treatment for CAC

目的：A村の特定健康診査受診者の非肥満者を対象とした健診結果の実態及び血糖と生活習慣の関連を明らかにする． 方法：A村の平成29年度特定健康診査受診者のうち，血圧や血糖等の服薬をしていない非肥満者533人を研究対象者とした．非肥満者533人を高血糖の有無による2群に分け，生活習慣との関連を分析した． 結果：健診結果では，非肥満者は，LDLコレステロールの平均値が特定健診受診者全体よりも高かった． 生活習慣では，非肥満者において高血糖群の方が定期的な運動をしている割合及び遅い時間の夕食をとっていない割合が有意に高く，生活習慣が良好な割合が高かった． 結論：非肥満者のうち高血糖の住民は，生活習慣には留意していると考えられた．今後は，詳細な生活習慣を確認し，その結果とともに健診結果に基づく指導が重要である．Objectives: The purpose of this study was to clarify the actual conditions of specific health checkups for non-obese individuals in A Village and the relationship between blood glucose and lifestyle habits. Method: The research participants were the 533 non-obese people who were not taking medication among of the all people who received a specific health checkup in A Village in 2017. We divided the 533 participants into two groups based on the presence or absence of hyperglycemia, and the relationship between blood glucose and lifestyle habits was analyzed. Results: Average LDL cholesterol was higher in the participants than in the recipients of specific health checkups overall. In terms of lifestyle habits, the proportion of participants in the hyperglycemic group who exercised regularly and those who did not eat dinner late at night was significantly higher than the non-hyperglycemic group, and the proportion of favorable lifestyle habits was higher. Conclusion: Non-obese people with hyperglycemia were considered to be aware of healthy lifestyle habits. It will be important for medical professional to ask more detailed questions about lifestyle during health checkups and to provide health guidance based on the results of blood test data.原

Three dimensional motion analyses for rehabilitation version of Awa Odori exercise and the expectancy of physical effects

‘Awa Odori Exercise -Rehabilitation version- was developed in 2006 for the new trial of physical exercise for the aging and the impaired person with lower balance performance in Tokushima prefecture, Japan. Public relations of this exercise had been spreading over Tokushima since then. The characteristics of the exercise were highly familiar with most of people in Tokushima because of popularity in original ‘Awa Odori’. This study proposed the efficacies of Awa Odori Exercise as a rehabilitation exercise. This exercise expected the flexible balance reinforcements and the substitution for walking training with prevention of fall, bedridden and participating restriction for the old people, also promoting the health in Tokushima

Relationship between Barthel Index scores during the acute phase of rehabilitation and subsequent ADL in stroke patients

The Barthel Index (BI) cannot be used to measure initial stroke severity or by extension, to stratify patients by severity in acute stroke trials because most patients are bedbound in the first few hours after stroke, either by their deficit or by medical directive. Our objectives were to clarify the threshold of acute BI for use in the prediction of subsequent independence in activities of daily living (ADL) and to assist in the definition of acute stroke rehabilitation goals. Subjects comprised 78 patients out of 191 inpatients admitted with acute stroke at our hospital during 2006-2007. The BI ADL score was divided into 2 ranges (BI≧60 and≦40), in a process similar to previous studies. During the acute period (from onset to approximately 3 weeks), all patients with a BI≧40 could improve their ADL in 6 months. Patients with a BI≦40 exhibited two ADL recovery outcomes (improved and no change) at 6 months. We also found that the skill level of basic activities related to standing was significant indicator of BI improvement (P<0.001). BI scores determined at approximately 3 weeks were reliable predictors of ADL disabilities at 6 months

Psychiatric disorders and clinical correlates of suicidal patients admitted to a psychiatric hospital in Tokyo

<p>Abstract</p> <p>Background</p> <p>Patients admitted to a psychiatric hospital with suicidal behavior (SB) are considered to be especially at high risk of suicide. However, the number of studies that have addressed this patient population remains insufficient compared to that of studies on suicidal patients in emergency or medical settings. The purpose of this study is to seek features of a sample of newly admitted suicidal psychiatric patients in a metropolitan area of Japan.</p> <p>Method</p> <p>155 suicidal patients consecutively admitted to a large psychiatric center during a 20-month period, admission styles of whom were mostly involuntary, were assessed using Structured Clinical Interviews for DSM-IV Axis I and II Disorders (SCID-I CV and SCID-II) and SB-related psychiatric measures. Associations of the psychiatric diagnoses and SB-related characteristics with gender and age were examined.</p> <p>Results</p> <p>The common DSM-IV axis I diagnoses were affective disorders 62%, anxiety disorders 56% and substance-related disorders 38%. 56% of the subjects were diagnosed as having borderline PD, and 87% of them, at least one type of personality disorder (PD). SB methods used prior to admission were self-cutting 41%, overdosing 32%, self-strangulation 15%, jumping from a height 12% and attempting traffic death 10%, the first two of which were frequent among young females. The median (range) of the total number of SBs in the lifetime history was 7 (1-141). Severity of depressive symptomatology, suicidal intent and other symptoms, proportions of the subjects who reported SB-preceding life events and life problems, and childhood and adolescent abuse were comparable to those of the previous studies conducted in medical or emergency service settings. Gender and age-relevant life-problems and life events were identified.</p> <p>Conclusions</p> <p>Features of the studied sample were the high prevalence of affective disorders, anxiety disorders and borderline PD, a variety of SB methods used prior to admission and frequent SB repetition in the lifetime history. Gender and age appeared to have an influence on SB method selection and SB-preceding processes. The findings have important implications for assessment and treatment of psychiatric suicidal patients.</p

Immunomodulatory effects of Lactobacillus biogenic administration in dogs

Lactobacillus biogenics were administered to four dogs for 56 days. The regulatory T cell (Treg) count was found to be increased in all four dogs on 56 days. On day 112, 56 days after completion of Lactobacillus probiotic administration, the percentage of Tregs was found to be decreased in three dogs. Plasma IgA levels tended to increase after stopping Lactobacillus administration. Metagenomic analysis of bacterial flora found in dog feces revealed that Firmicutes, Proteobacteria, Bacteroidetes, and Fusobacteria were predominantly found in all 4 dogs. Analysis of fecal microbiomes of species level on day 56 showed that 99 % members of genus Prevotella belonged to species copri. This study demonstrates some of the immunomodulatory effects of Lactobacillus probiotics on dogs
