西部北太平洋亜熱帯海域の定点(北緯22.5度,東経131.8度)で,2004年から2006年の各年の夏季に,調査地点の500km以内に台風が通過した後の10日以内におこなわれた植物プランクトン群集組成の調査結果を解析した。2006年の台風はEWINIARとBILISで,最接近時の移動速度がそれぞれ2.8と4ms^<-1>であり,2004年のKOMPUS(6.5ms^<-1>)と2005年のHAITANG(7.9ms^<-1>)に比べて遅かった。人工衛星による観測では,2006年のこれらの台風が通過した後,海表面水温が低下し,クロロフィルaが調査地点を含む広範囲において増加していた。また,植物プランクトンが増加しており,優占種はPlanktoniella solで,細胞数は4×10^<7> cells m^<-2>であり,2004年(1×10^5 cells m^<-2>)と2005年(5×10^4 cells m^<-2>)に比べて2-3桁高かった。さらに,シアノバクテリアおよびバクテリアの炭素態現存量も,2004年と2005年に比べ約2倍高かった。同じ地点で2002年12月から2005年7月まで実施したセジメントトラップによる沈降粒子観測では,台風の影響と考えられる変動はみられなかった。Phytoplankton communities and carbon biomass were investigated at 22.5°N, 131.8°E in the western North Pacific subtropical region between 2004 and 2006 within 10 days of a typhoon passing within 500km of the survey point. The typhoons of 2006 were EWINIAR and BILIS. The translation speeds of these typhoons at the nearest area from the survey point were 2.8 and 4 m s^<-1>, respectively slower than that of 2004's typhoon KOMPUS (6.5 m s^<-1>) and 2005's typhoon HITANG (7.9 m s^<-1>). After the 2006 typhoons, the sea surface water temperature decreased, and the chlorophyll-a increased over a wide area, including the investigation point. The number of diatoms in 2006 increased, and the carbon biomass was 5-10 times higher compared with 2004 and 2005. The dominant species of diatom was Planktoniella sol with 4×10^7 cells m^<-2> which was considerably higher than the cell density 2004 (1×10^5 cells m^<-2>) and 2005 (5×10^4 cells m^<-2>). 2006 carbon biomass of the cyanobacteria and bacteria was twice as high as that of other years. The settling particle flux after a specific typhoon was not increased, in contrast with the hypothesis we derived from the increasing biomass data.

Background: Controlling serum cholesterol is critical to prevent cardiovascular disease in patients with dyslipidaemia. Guidelines emphasise the need to select treatment for dyslipidaemia based on specific patient profiles; however, there is little information about the serum cholesterol levels of patients in each profile in Japan. Therefore, we aimed to describe the serum cholesterol levels and prevalence of uncontrolled cases in Japanese patients with dyslipidaemia.Methods: We included data for patients with dyslipidaemia between 2003 and 2007 from the BioBank Japan Project (66 hospitals). Then, we reported their serum cholesterol levels by age, body mass index, glycaemic control (glycated haemoglobin A1c), blood pressure, smoking, drinking, comorbidity and medication profiles.Results: We included 22,189 male and 21,545 female patients. The mean serum low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG) and non-HDL-C levels in males were 117.4 mg/dL, 51.0 mg/dL, 187.6 mg/dL and 153.6 mg/dL, respectively; the corresponding levels in females were 129.5 mg/dL, 60.5 mg/dL, 144.9 mg/dL and 157.9 mg/dL, respectively. In both males and females, the LDL-C levels were the highest in the following profiles: age 19–44 years, body mass index 18.5–22 kg/m2, glycated haemoglobin A1c <6.0%, never smoker, chronic respiratory disease as a comorbidity and no medication use.Conclusions: These data provide details of serum cholesterol levels by risk-factor profile in patients with dyslipidaemia and could add evidence of treatment decisions.

Background: Evidence of characteristics of Japanese patients with diabetes from a large-scale population is necessary. Few studies have compared glycaemic controls, complications and comorbidities between type 1 and 2 diabetic patients. This paper focuses on illustrating a clinical picture of Japanese diabetic patients and comparing glycaemic control and prognoses between type 1 and 2 diabetes using multi-institutional data.Methods: The BioBank Japan Project enrolled adult type 1 and 2 diabetic patients between fiscal years 2003 and 2007. We have presented characteristics, controls of serum glucose, cholesterol and blood pressure, prevalence of complications and comorbidities and survival curves. We have also shown glycaemic controls according to various individual profiles of diabetic patients.Results: A total of 558 type 1 diabetic patients and 30,834 type 2 diabetic patients participated in this study. The mean glycated haemoglobin A1c was higher in type 1 diabetes than in type 2 diabetes. In the type 1 diabetic patients, the glycated haemoglobin A1c had no consistent trend according to age and body mass index. The Kaplan–Meier estimates represented a longer survival time from baseline with type 1 diabetes than with type 2 diabetes. Compared with type 1 diabetic patients, type 2 diabetic patients had double the prevalence of macrovascular complications.Conclusions: This work has revealed detailed plasma glucose levels of type 1 and 2 diabetic patients according to age, body mass index, blood pressure, serum cholesterol levels and smoking and drinking habits. Our data have also shown that the prognosis is worse for type 2 diabetes than for type 1 diabetes in Japan.

Background: The number of patients with diabetes is increasing worldwide. Macrovascular disease, chronic kidney disease, chronic respiratory disease, cancer and smoking frequently accompany type 2 diabetes. Few data are available related to mortality of Asians with diabetes associated with these serious comorbidities. The present study aimed to quantify the excess mortality risks of type 2 diabetic patients with comorbidities.Methods: We analysed the available records of 30,834 Japanese patients with type 2 diabetes from the BioBank Japan Project between 2003 and 2007. Men and women were followed up for median 8.03 and 8.30 years, respectively. We applied Cox proportional hazard model and Kaplan–Meier estimates for survival curves to evaluate mortality in diabetic patients with or without macrovascular disease, chronic respiratory disease, chronic kidney disease, cancer and smoking.Results: Adjusted hazard ratios (HRs) for mortality were 1.39 (95% CI, 1.09–1.78) for male sex, 2.01 (95% CI, 1.78–2.26) per 10-year increment of age. Adjusted HRs of primary interest were 1.77 (95% CI, 1.42–2.22), macrovascular disease; 1.58 (95% CI, 1.08–2.31), chronic respiratory disease; 2.03 (95% CI, 1.67–2.47), chronic kidney disease; 1.16 (95% CI, 0.86–1.56), cancer; and 1.74 (95% CI, 1.30–2.31), current smoking.Conclusions: Diabetic patients with a past or current history of chronic kidney, macrovascular or respiratory diseases or smoking habit have exhibited the highest risk of mortality. Data were limited to those of survivors of comorbidities but we propose the need to improve comorbidities and terminate cigarette smoking for better prognosis in patients with diabetes.

In citrus trees, a technique for predicting the number of flowers is needed to prevent inconsistent fruit production over time. In this study, we investigated whether a flowering-related gene, citrus FLOWERING LOCUS T (CiFT), can be used to predict floral production. We quantified CiFT expression levels in stems of Satsuma mandarin (Citrus unshiu Marc.) trees planted at two remote locations. We collected samples over 3 years, and determined that the CiFT mRNA levels in November were strongly correlated with the number of flowers produced the following spring. The correlation between CiFT expression and floral production exhibited almost no differences among years or between sample collection sites. Thus, the CiFT expression level in November can be used to predict the number of flowers the following spring, and this prediction method can be used at different locations and over several years. To verify the practical utility of this method, Satsuma mandarin shoots were transported in November from eight locations across Japan to our laboratory under cool conditions. Transport times were approximately 4–72 h, and samples were immediately frozen upon arrival. The CiFT expression levels in transported stems correlated with the number of flowers in the following spring. Additionally, those correlations were similar in transported samples and samples that were frozen immediately after collection. Our results suggest that the number of flowers can be predicted even with the CiFT expression levels quantified in transported samples.

Although several studies have reported the effects of long-chain polyunsaturated fatty acid (LCPUFA) supplementation on the mood in healthy adults, the effects of LCPUFA on elderly individuals remain unclear. Thus, we hypothesized that LCPUFA supplementation improves mood in the elderly. To address this hypothesis, 115 elderly Japanese men aged 55-64 years were assigned and randomly allocated to the LCPUFA or placebo group. Participants received 4 weeks of supplementation with LCPUFAcontaining oil (docosahexaenoic acid (DHA) 300 mg/day, eicosapentaenoic acid (EPA) 100 mg/day, arachidonic acid (ARA) 120 mg/day) or a placebo oil. Mood was assessed using the Profile of Mood States (POMS) before and after supplementation as the secondary outcome in a previously performed randomized controlled trial on cognitive function. A total of 113 participants completed the supplementation period. One hundred participants (LCPUFA, n = 51; placebo, n = 49) who were eligible for evaluation of mood were analyzed. Increases in vigor scores on POMS, reflecting a positive mood, were significantly larger in the LCPUFA group than in the placebo group (LCPUFA, +1.8; placebo, −0.5). No significant differences were observed in changes in other negative mood scores between groups. DHA and ARA content in plasma phospholipids were increased by 0.8% and 0.7%, respectively, in the LCPUFA group, and were significantly larger than those in the placebo group. Dietary DHA, EPA, and ARA intake was unchanged during the study. These results suggest that LCPUFA supplementation may improve vigor (positive mood) in elderly Japanese men.

In mass spectrometry, analytes must be released in the gas phase. There are two representative methods for the gasification of the condensed samples, i.e., ablation and desorption. While ablation is based on the explosion induced by the energy accumulated in the condensed matrix, desorption is a single molecular process taking place on the surface. In this paper, desorption methods for mass spectrometry developed in our laboratory: flash heating/rapid cooling, Leidenfrost phenomenon-assisted thermal desorption (LPTD), solid/solid friction, liquid/solid friction, electrospray droplet impact (EDI) ionization/desorption, and probe electrospray ionization (PESI), will be described. All the methods are concerned with the surface and interface phenomena. The concept of how to desorb less-volatility compounds from the surface will be discussed.

Theanine, an amino acid in tea, has significant anti-stress effects on animals and humans. However, the effect of theanine was blocked by caffeine and gallate-type catechins, which are the main components in tea. We examined the anti-stress effect of green tea with lowered caffeine, low-caffeine green tea, on humans. The study design was a single-blind group comparison and participants (n=20) were randomly assigned to low-caffeine or placebo tea groups. These teas (≥500 mL/d), which were eluted with room temperature water, were taken from 1 week prior to pharmacy practice and continued for 10 d in the practice period. The participants ingested theanine (ca. 15 mg/d) in low-caffeine green tea. To assess the anxiety of participants, the state-trait anxiety inventory test was used before pharmacy practice. The subjective stress of students was significantly lower in the low-caffeine-group than in the placebo-group during pharmacy practice. The level of salivary α-amylase activity, a stress marker, increased significantly after daily pharmacy practice in the placebo-group but not in the low-caffeine-group. These results suggested that the ingestion of low-caffeine green tea suppressed the excessive stress response of students. This study was registered at the University Hospital Medical Information Network (ID No. UMIN14942).

The feline F12 gene was examined to identify a mutation associated with coagulation factor XII (FXII) deficiency in a litter of 6 cats, including 2 cats with severely reduced FXII activity (7.1 and 9.3%, respectively) and 4 cats with moderately reduced FXII activity (range 36.0 to 46.3%). Cats with severely reduced FXII activity were homozygous for a G to C missense mutation in exon 13 of the F12 gene, resulting in an amino acid change (p.G544A). Cats with moderately reduced FXII activity were heterozygous for this mutation. Expression studies revealed reduced secretion of p.G544A mutant FXII protein from transfected HEK293 cells compared with wild type FXII. These results reveal a novel F12 mutation in FXII deficient cats and define the underlying mechanism for low FXII activity in homozygotes.

High-intensity interval training (HIIT) has recently received much attention as a new option for aerobic training. Despite its smaller time requirement, HIIT has been reported to have a greater effect than continuous moderate-intensity training on fat loss, especially a decrease in truncal adiposity. We therefore examined whether long-term HIIT preferentially modulates truncal adiposity rather than peripheral adiposity, especially thigh adiposity, where local muscle energy consumption increased profoundly during HIIT. We also examined the association between changes in adipose tissue distribution and serum adiponectin level. Twelve healthy male participants (28-48 years old) were assigned to a group that performed HIIT using only a leg ergometer (L-HIIT, n = 7) or to a group that performed HIIT using both leg and arm ergometers (LA-HIIT, n = 5) twice weekly for 16 weeks. The training programs consisted of 8 to 12 sets of >90% VO2 peak for 1 min, with 1 min of very light active recovery. Body composition analyses as well as aerobic fitness and measurements of serum adiponectin were performed at baseline and after intervention. A linear improvement in aerobic fitness was observed along with a decrease in leg fat (5.4 ± 1.7 vs. 5.1 ± 1.7 kg, p < 0.05) near the main working muscles during HIIT in the combined (L+LA-HIIT) group. Moreover, there was an association of decrease in leg fat or thigh adiposity with improvement in aerobic fitness in the combined group (ρ = -0.59, p < 0.05; and ρ = -0.71, p < 0.05, respectively). Visceral adiposity was decreased in L-HIIT (115 ± 45 vs. 100 ± 47 cm2, p < 0.05), however no decrease was observed in total fat or truncal fat in either group. No change was observed in serum adiponectin concentration in either group. Changes in serum adiponectin were associated with changes in visceral adiposity in the combined group (ρ = -0.72, p < 0.01). Regional rather than whole-body fat loss was observed after a 16-week HIIT program.

Aim: The aim of the present study was to investigate how small dense low-density lipoprotein cholesterol (sdLDL-C) compared with LDL-C affect the long-term prognosis in patients with stable coronary artery disease (CAD). Methods: sdLDL-C measured by heparin magnesium precipitation and LDL particle size measured by non-denatured gradient-gel electrophoresis were compared in 190 consecutive CAD patients who underwent coronary arteriography between 2003 and 2004 who did or did not develop cardiovascular events during a seven-year follow-up period. Cardiovascular events were death caused by cardiovascular diseases(CVDs), onset of acute coronary syndrome, need for coronary and peripheral arterial revascularization, hospitalization for heart failure, surgical procedure for any CVDs, and/or hospitalization for stroke. Results: First-time cardiovascular events were observed in 72 patients. Those who experienced cardiovascular events were older and had higher prevalence rates of hypertension and diabetes; significantly higher Gensini coronary atherosclerotic scores; significantly higher levels of sdLDL-C, sdLDL-C/LDL-C, and LDL-C/high-density lipoprotein cholesterol (HDL-C) ratios; and greater glycated hemoglobin(Hb)A1c and brain natriuretic peptide (BNP) levels. They also had significantly smaller LDL particle sizes, HDL-C, apolipoprotein A-1, and estimated glomerular filtration rate (GFR) compared with patients without cardiovascular events. Conversely, LDL-C, non-HDL-C, apolipoprotein B, remnantlike particle cholesterol, and high-sensitivity C-reactive protein (hs-CRP) levels were similar between the two groups. A Kaplan-Meyer event-free survival curve demonstrated that patients with sdLDL-C≥35 mg/dL (median level) had significantly poorer prognosis compared with those with lower sdLDL-C levels, while patients with LDL-C ≥100 mg/dL had a non-significantly lower survival rate. Conclusion: These results confirm that sdLDL-C is a very promising biomarker to predict future cardiovascular events in the secondary prevention of stable CAD.

The author of the fourth Gospel is named John and understands Jesus Christ as the Logos. The Logos means the Word of God. John's Christology is called Christology of the Logos. Jesus is not so much a prophet who communicates to people the Word of God as the Word of God itself. Jesus, the Logos exists with God (Father) from the eternal beginning, and has the divine nature. Christian God is God of the Trinity who has three persons (personae), the Father, the Son and the Holy Spirit. Jesus, the Son and Logos was sent from the Father to the world, and born as a human being (John 1: 14, 18). This event is named the incarnation of the Logos. The glory of God approached more nearly to us through Jesus who was the incarnated Logos, and could move with Jesus' flesh. The existence of God became more familiar to people in the New Testament than in the Old Testament. We can be formed as the form of Christ and have the divine nature through Christ's person.

This study was designed to evaluate the safety profile of adding telaprevir to therapy using pegylated interferon-alfa-2b and ribavirin (PR) using real world patient data obtained from a nationwide Japanese interferon database. This retrospective cohort study compared telaprevir-based triple therapy (T/PR) with PR therapy. The study population comprised patients with genotype 1 chronic hepatitis C represented in the database between December 2009 and August 2015. The primary endpoint was dropout from treatment due to adverse events during the relevant standard treatment duration based on guidelines from the Japan Society of Hepatology. The dropout odds ratio (OR) and 95% confidence interval (95% CI) were calculated using univariate logistic regression analysis. Covariates were detected using a stepwise logistic regression analysis, and the adjusted OR and 95% CI were calculated. A total of 25,989 patients were registered, and 4,619 patients (T/PR: 1,334, PR: 3,285) were appropriate for primary endpoint analysis. The dropout rate due to adverse events was lower in the T/PR group (13.4%) than in the PR group (22.6%) (OR: 0.530; 95% CI, 0.444-0.633). After adjustment for the covariates detected by stepwise selection, the OR was 0.529 (95% CI, 0.441-0.634). Our study showed that there was a difference in dropout rate between real world T/PR and PR therapy in Japan. Although the addition of telaprevir to PR therapy may improve treatment continuity under the care of hepatologists, this study could not fully determine which therapy was safer or the factors influencing this result. Therefore, additional research will be required to confirm this.

An 80-year-old man with Ebstein's anomaly and ductus arteriosus aneurysm is reported. He was admitted with bradycardiac atrial fibrillation and right ventricular failure. For the control of brady-arrhythmia, a permanent pacemaker was implanted. Two-dimensional echocardiogram revealed distal displacement of the septal tricuspid valve. Aortography and computed tomography showed ductus arteriosus aneurysm. This is the first report of the association of Ebstein's anomaly and non-patent ductus arteriosus aneurysm.

l-Menthol increases drug partitioning on the surface of skin, diffusion of drugs in the skin, and lipid fluidity in the stratum corneum and alters the rigidly arranged lipid structure of intercellular lipids. However, l-menthol is a solid at room temperature, and it is difficult to determine the effects of l-menthol alone. In this study, we vaporized l-menthol in order to avoid the effects of solvents. The vaporized l-menthol was applied to the stratum corneum or lipid models comprising composed of ceramides (CER) [EOS], the longest lipid acyl chain of the ceramides in the stratum corneum lipids that is associated with the barrier function of the skin; CER [NS], the shorter lipid acyl chain of the ceramides, and the most components in the stratum corneum of the intercellular lipids that is associated with water retention in the intercellular lipid structure of the stratum corneum; cholesterol; and palmitic acid. Synchrotron X-ray diffraction, differential scanning calorimetry, and attenuated total reflection Fourier transform infrared spectroscopy analyses revealed that the lipid models were composed of hexagonal packing and orthorhombic packing structures of different lamellar periods. Taken together, our results revealed that l-menthol strongly affected the lipid model composed of CER [EOS]. Therefore, l-menthol facilitated the permeation of drugs through the skin by liquid crystallization of the longer lamellar structure. Importantly, these simple lipid models are useful for investigating microstructure of the intercellular lipids in the stratum corneum.

Humans cannot synthesize fat-soluble vitamins such as vitamin E and vitamin K. For this reason, they must be obtained from the diet via intestinal absorption. As the deficiency or excess of these vitamins has been reported to cause several types of diseases and disorders in humans, the intestinal absorption of these nutrients must be properly regulated to ensure good health. However, the mechanism of their intestinal absorption remains poorly understood. Recent studies on cholesterol using genome-edited mice, genome-wide association approaches, gene mutation analyses, and the development of cholesterol absorption inhibitors have revealed that several membrane proteins play crucial roles in the intestinal absorption of cholesterol. Surprisingly, detailed analyses of these cholesterol transporters have revealed that they can also transport vitamin E and vitamin K, providing clues to uncover the molecular mechanisms underlying the intestinal absorption of these fat-soluble vitamins. In this review, we focus on the membrane proteins (Niemann-Pick C1 like 1, scavenger receptor class B type I, cluster of differentiation 36, and ATP-binding cassette transporter A1) that are (potentially) involved in the intestinal absorption of cholesterol, vitamin E, and vitamin K and discuss their physiological and pharmacological importance. We also discuss the related uncertainties that need to be explored in future studies.
