    Abstract: We investigated the effect of royal jelly (RJ), a natural secretion from worker bees, on the endurance training-induced mitochondrial adaptations in skeletal muscles of ICR mice. Mice received either RJ (1.0 mg/g body weight) or distilled water for three weeks. The mice in the training group were subjected to endurance training (20 m/min; 60 min; 5 times/week). There was a main effect of endurance training on the maximal activities of the mitochondrial enzymes, citrate synthase (CS), and β-hydroxyacyl coenzyme Adehydrogenase (β-HAD), in the plantaris and tibialis anterior (TA) muscles, while no effect of RJ treatment was observed. In the soleus muscle, CS and β-HAD maximal activities were significantly increased by endurance training in the RJ-treated group, while there was no effect of training in the control group. Furthermore, we investigated the effects of acute RJ treatment on the signaling cascade involved in mitochondrial biogenesis. In the soleus, phosphorylation of 5′-AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) were additively increased by a single RJ treatment and endurance exercise, while only an exercise effect was found in the plantaris and TA muscles. These results indicate that the RJ treatment induced mitochondrial adaptation with endurance training by AMPK activation in the soleus muscles of ICR mice.

    Abstract: Acute suppurative thyroiditis (AST) accompanied by an abscess is a rare clinical case. Hemodialysis patients are at risk for infections. Sepsis mortality was from 100 to 300 times higher for chronic dialysis patients than that for the general public. Thus, special care should be taken against infection in patients under hemodialysis.

    Abstract: Polyunsaturated fatty acid (PUFA) is an essential class of dietary fatty acids, because of the lack of endogenous enzymes for desaturation in humans. Previous research on n-3 PUFA has demonstrated several health benefits and antiatherogenic actions, but n-6 PUFA have not received much research attention. We investigated whether serum fatty acid composition, especially n-6 PUFAs and desaturase activity, is associated with obesity in type 2 diabetic patients. Subjects were 80 type 2 diabetic patients (age: 60.3±13.9 years) who had no EPA agent intake. They were divided into two groups: obese group (n=52) with a BMI more than 25 kg/m2 and non-obese group (n=28) with a BMI less than 25 kg/m2. Fatty acid levels in serum were measured using gas chromatography. The desaturase activity for n-6 PUFAs was calculated as the arachidonic acid/dihomo-gamma-linolenic acid (DGLA) ratio for Δ5 desaturase (D5D). The obese group revealed a higher saturated fatty acid (SFA) and DGLA levels than those in the non-obese group. No significant difference was observed in the serum n-3 PUFA levels between the two groups. The D5D index of the obese group was significantly lower than that of the non-obese group. Serum DGLA levels showed significant positive correlations with waist circumference, BMI, triglyceride, and hepatic AST and ALT levels. Moreover, SFA showed a significant positive correlation with BMI. The levels of D5D index showed a significant negative correlation with BMI. Increase in serum DGLA levels was related to the number of metabolic factors. These results suggest that type 2 diabetic patients with obesity had changes in their blood fatty acid profile, especially increased DGLA levels. The high levels of blood DGLA indicate downregulation of n-6 metabolism, probably caused by the decreased activity of D5D. The fat quality in the diet and changes in desaturase activity might contribute to the development of obesity. Disclosure M. Saito: None. M. Higa: None. T. Suzuki: None. M. Michishita: None. M.

    Abstract: The immune system is a very complex and dynamic cellular system, and its intricacies are considered akin to those of human society. Disturbance of homeostasis of the immune system results in various types of diseases; therefore, the homeostatic mechanism of the immune system has long been a subject of great interest in biology, and a lot of information has been accumulated at the cellular and the molecular levels. However, the sociological aspects of the immune system remain too abstract to address because of its high complexity, which mainly originates from a large number and variety of cell–cell interactions. As long‐range interactions mediated by cytokines play a key role in the homeostasis of the immune system, cytokine secretion analyses, ranging from analyses of the micro level of individual cells to the macro level of a bulk of cell ensembles, provide us with a solid basis of a sociological viewpoint of the immune system. In this review, as the first step toward a comprehensive understanding of immune cell sociology, cytokine secretion of immune cells is surveyed with a special emphasis on the single‐cell level, which has been overlooked but should serve as a basis of immune cell sociology. Now that it has become evident that large cell‐to‐cell variations in cytokine secretion exist at the single‐cell level, we face a tricky yet interesting question: How is homeostasis maintained when the system is composed of intrinsically noisy agents? In this context, we discuss how the heterogeneity of cytokine secretion at the single‐cell level affects our view of immune cell sociology. While the apparent inconsistency between homeostasis and cell‐to‐cell heterogeneity is difficult to address by a conventional reductive approach, comparison and integration of single‐cell data with macroscopic data will offer us a new direction for the comprehensive understanding of immune cell sociology. © 2012 IUBMB Life, 65(1):28–34, 2013

    Abstract: It is well known the primary aldosteronism (PA) is most common endocrinological hypertension and accounted for 10% among all hypertension population, and it develops cardiovascular disease more frequently than blood pressure matched essential hypertension. Those patients with bilateral hyperaldosteronism, called idiopathic hyperaldosteronism (IHA), or unwilling for surgical treatment are treated by mineralcorticoid receptor antagonists (MRAs). Although it had been unclear how titrate MRAs to prevent atherosclerotic cardiovascular events, a managemental target for those patients was recently reported as plasma renin activity (PRA) ≥ 1.0 ng/ml/hr to prevent cardiovascular events (Hundemer GL, et. al. Lancet Diabetes Endocrinol. 2018 Jan;6(1):51-59). Thus, we investigated 77 cases of adrenal venous sampling performed patients with PA and followed up for 3 years in our hospital since 2007, including 24 males and 53 females, and their mean age was 56.3 ± 12.5 years old. All patients underwent AVS and showed bilateral hyperaldosteronism and treated with MRAs and followed up more than 3 years. We collected blood pressure, serum sodium and potassium concentration, estimated glomerular filtration ratio (eGFR), PRA, plasma aldosterone concentration (PAC), atherosclerotic parameter, such as mean intima media thickness (IMT), brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI). We evaluated the relationship of those patients’ PRA and aldosterone to renin ratio (ARR) with eGFR, IMT, baPWV, and ABI. The change of mean IMT after 3 year-follow up were 0.03 ± 0.11 mm vs. 0.06 ± 0.09 mm for well controlled (PRA ≥ 1.0 ng/ml/hr) and poorly controlled (PRA & lt; 1.0 ng/ml/hr), respectively, and no significant difference between them. In the other hand, the change of mean IMT after 3 year-follow up showed 0.03 ± 0.10 mm vs. 0.08 ± 0.10 mm for well controlled (PRA ≥ 1.0 ng/ml/hr and ARR & lt;20) and poorly controlled (PRA & lt; 1.0 ng/ml/hr or ARR ≥ 20), respectively, and the mean IMT increase was significantly lower in this group. The mean IMT increase showed significantly lower only with PRA ≥ 1.0 ng/ml/hr and ARR & lt;20 rather than PRA ≥ 1.0 ng/ml/hr alone. In our results, both PRA ≥ 1.0 ng/ml/hr and ARR & lt;20 are important to prevent or improve atherosclerosis, rather than only PRA ≥ 1.0 ng/ml/hr and should be titrated MRAs to achieve this target. In conclusion, our result revealed the titration of MRAs is important to prevent atherosclerotic cardiovascular event and not only PRA ≥ 1.0 ng/ml/hr, but both PRA and ARR & lt;20 should be achieved.

    Abstract: Increasing evidence supports a more prominent role for postprandial glucose (PPG) regulation in the management of type 2 diabetes. Viscous dietary fibers including oat and barley β-glucan are one of the most effective classes of functional food ingredients for reducing PPG. We investigated the effect of high β-glucan barley on postprandial plasma glucose and C-peptide levels using a meal tolerance test and continuous glucose monitoring (CGM) in 15 subjects with normal glucose tolerance (NGT) and 29 type 2 diabetic patients. A 500-kcal meal tolerance test, using white rice alone (white rice) or white rice mixed with 50% of barley (Kirari-mochi®) containing 1.5-times β-glucan higher than usual barley (barley), was performed, and plasma glucose and C-peptide levels were measured every 30 minutes for 180 minutes. Daily glucose variability was measured using CGM over two days, while subjects consumed 1600-kcal or 1800-kcal test meals consisting of white rice or barley. Subsequently, a meal tolerance test with identical carbohydrate quantity (52g carbohydrate) with or without 1.8g of β-glucan, was performed in 7 diabetic patients. In NGT subjects and diabetic patients, the incremental area under the curve (AUC) of plasma glucose and C-peptide levels for 180 minutes after the meal tolerance test were significantly decreased following the consumption of barley compared to the consumption of white rice alone. The studies using CGM have demonstrated that the consumption of barley lead to a significant decrease in the 24-h standard deviation of blood glucose (24-h SDBG) and mean amplitude of glycemic excursion (MAGE) in diabetic patients. Similar results were obtained in subsequent tests with identical carbohydrate quantity but with β-glucan. In conclusion, these results suggest that high-β-glucan barley may contribute to decreased PPG levels and endogenous insulin secretion in both patients with type 2 diabetes and the subjects with NGT.

    Abstract: Aim: Elevated saturated fatty acid (SFA) and decreased polyunsaturated fatty acid (PUFA) levels, especially n-3 PUFAs levels are important in the development of obesity and metabolic syndrome, but there are few accounts of the relationship between fatty acid composition and diabetic kidney disease. We investigated whether serum fatty acid composition, especially SFA and PUFA, are associated with urine albumin excretion (UAE) and estimated glomerular filtration rate (eGFR) in obese type 2 diabetic patients. Research Design and Method: The subjects were 85 patients (age: 60.3±13.9 years old, 47 male and 38 female) who were not taking EPA agents. They were divided into two groups, i.e., Obese group (n=54) with a BMI of more than 25 kg/m2 and non-Obese group (n=31) with a BMI below 25 kg/m2. Serum levels of fatty acids were measured by gas chromatography. Results: In the Obese group, the serum levels of palmitic acids and stearic acids, which belong to SFA, and dihomo-gamma-linolenic acid (DGLA), which is an n-6 PUFA, were significantly higher than those in the non-Obese group. No significant differences were seen in the serum levels of n-3 PUFA. UAE in the Obese group was 218.8±88.9 mg/gCr, which tended to be higher than that in the non-Obese group (135.9±49.0 mg/gCr), but there were no significant differences in eGFR between the two groups. The serum levels of palmitic acids, stearic acids, and DGLA showed significant positive correlations with UAE and eGFR in the Obese group, while no significant correlation was seen in the non-Obese group. Palmitic acids and DGLA were correlated with serum adiponectin and leptin levels. Conclusion: These results suggest that an excessive lipid intake may play an important role in the development of not only obesity but also diabetic kidney disease. The high levels of blood SFA and n-6 PUFA might contribute to the diabetic kidney disease progression via hyperfiltration and inflammatory effects in type 2 diabetes patients with obesity.

    Abstract: Aim: Polyunsaturated fatty acids (PUFAs) are essential fatty acids, because they cannot be synthesized in the body and must be taken from food, but excessive intake may cause obesity. Therefore, the measurement of serum fatty acid composition is useful for monitoring the fat composition of the diet. In recent years, accumulating evidence has indicated the importance of gut microbiota in maintaining human health. The aim of our study was to evaluate the relationship between fatty acid composition and gut microbiota in obese patients with type 2 diabetes. Research Design and Method: The subjects included 100 patients (age: 60.3±13.9 years, BMI 27.5±5.8 kg/m2) who were not taking EPA agents. They were divided into two groups, i.e., obese group (n=64) with a BMI of greater than 25 kg/m2 and non-obese group (n=36) with a BMI less than 25 kg/m2. Serum levels of fatty acids were measured using gas chromatography. In 45 of 100 patients, gut microbiota profiles were measured using T-RFLP methods. Results: The serum levels of dihomo-gamma-linolenic acid (DGLA), which is an n-6 PUFA, and palmitic acid, a saturated fatty acid (SFA), were significantly higher in the obese group than in the non-obese group. No significant differences were observed in the serum levels of n-3 PUFA. The ratio of Firmicutes/Bacteroidetes in the fecal microbiota was significantly lower in the patients with high serum levels of DGLA. The rate of Bacteroidetes showed a significant positive correlation with serum DGLA and palmitic acid. Conclusion: These results suggest that high levels of serum DGLA may play an important role in the development of not only obesity but also gut microbiota in type 2 diabetes patients. The fat quality in the diet might contribute to the development of obesity. Disclosure M. Higa: None. M. Kawai: None. R. Eto: None. F. Ayako: None. G. Sato: None. M. Hijikata: None. K.
