    ABSTRACT: The effects of relative humidity (RH) on the antioxidant properties of α-tocopherol (10, 20, 42, and 84ppm) were determined in stripped corn oil oxidised at 60°C. The degree of oxidation in oils was determined by analysing headspace oxygen content and conjugated dienoic acids (CDAs). Changes in moisture and α-tocopherol content were also monitored. The oxidative stability of stripped corn oil and stability of α-tocopherol differed significantly depending on the RH. As the concentration of α-tocopherol increased from 10 to 84ppm, oxidative stability decreased significantly irrespective of RH. The remaining α-tocopherol content decreased as RH increased, suggesting an important role for moisture content in the stability of α-tocopherol. Antioxidant properties of α-tocopherol were greatly influenced by both moisture content in oil and α-tocopherol concentration.

    ABSTRACT: Recent findings of increased cathelicidin protein and its proteolytic fragments in rosacea suggest a pathogenic role for cathelicidin in this disease. The relationship between cathelicidin and protease-activated receptor 2 (PAR-2) is therefore of interest, as PAR-2, expressed principally in keratinocytes, regulates pro-inflammatory cytokine expression in the skin. The purpose of this study was to determine the relationship between expression of PAR-2 and cathelicidin in rosacea and to test the effect of direct PAR-2 activation on cathelicidin expression in keratinocytes.

    ABSTRACT: Abstract The complete mitogenome (KM507782) of the Black-tailed gull L. crassirostris was 16,746 bp long, with A 30.6% (5128 bp), T 24.3% (4076 bp), C 30.9% (5176 bp), and G 14.1% (2366 bp). Total length of 13 protein-coding genes was 11,396 bp and 12 of them except for ND6 were encoded in heavy strand. The three initiation codons ATG, GTG and ATT were used in the protein-coding genes. The ATG was a common initiation codon which was found in most of the protein-coding genes, whereas GTG was used in COX1 and ND5 and ATT in only ND3, respectively. The total length of 22 tRNA genes was 1550 bp, ranging from 66 bp (tRNA(Ser(AGY))) to 74 bp (tRNA(Leu(UUR)) and tRNA(Ser(UCN))).

    ABSTRACT: Antioxidant systems against reactive oxygen species (ROS) are the important factors to regulate homeostasis in various cells, tissues and organs. Although ROS are known to cause to muscular disorders, the effects of mitochondrial ROS in muscle physiology have not been fully understood. Here, we investigated the effect of ROS on muscle mass and function using mice deficient in peroxiredoxin 3 (Prx3), which is a mitochondrial antioxidant protein. Ablation of Prx3 deregulated mitochondrial network and membrane potential of myotubes, in which ROS levels were increased. We showed that DNA content of mitochondria and ATP production are also reduced in Prx3 KO muscle. Of note, the mitofusin 1 and 2 protein levels decreased in Prx3 KO muscle, a biochemical evidence of impaired mitochondrial fusion. Contractile dysfunction was examined by measuring isometric forces of isolated EDL and soleus muscles. Maximum absolute forces in both the EDL and soleus muscles were not significantly affected in Prx3 KO mice. However, fatigue trials revealed that the decrease in relative force was greater and more rapid in soleus from Prx3 KO compared to wild type mice. Taken together, these results suggest that Prx3 plays a crucial role in mitochondrial homeostasis and, thereby controls the contractile functions of skeletal muscle.

    ABSTRACT: This study assessed ultrasound visibility of spinal structures in children and observed the extent of local anesthetic spread within the epidural space during caudal block. Spinal structures were evaluated with ultrasound from the sacral area to the thoracic area in 80 children, and drug spread levels were observed after caudal injection of 0.5, 1.0, 1.25 and 1.5 mL/kg local anesthetic. The conus medullaris, dural sac and dura mater were easily identified with ultrasound in most children. However, ligamentum flavum visibility declined with increasing vertebral level and markedly decreased at the thoracic level in children older than 7 mo or heavier than 8.5 kg. Drug spread was higher with increasing volume (p < 0.001) and in children ≤12 mo more than children >12 mo (p < 0.001); drug spread was significantly correlated with age (R(2) = 0.534). Spread levels assessed with ultrasound were roughly two to three segments lower than those in previous radiologic studies.

    ABSTRACT: We hypothesized that triglyceride-raising APOA5-1131T > C may contribute to the increased risk of obesity in associated with dietary intake in Korean premenopausal women whose minor allele frequency is higher than that in Western people. Genetically-unrelated Korean premenopausal women (20 ~ 59 yrs, n = 1128) were genotyped for APOA5-1131T > C. Anthropometric, metabolic parameters and dietary intakes were analyzed. Odds ratios (ORs) for obesity risk (BMI ≥ 25.0kg/m2) were calculated. Genotype distribution of APOA5-1131T > C of study subjects were like: TT:49.9%, TC:40.8% and CC:9.3%. We found a significant interaction between APOA5-1131T > C and total energy intake (TEI) for obesity after adjusted for age, cigarette smoking and alcohol consumption (p < 0.001). The risk of obesity in CC homozygotes compared to T carriers (TT + TC) was significantly increased when the subjects consume higher TEI (≥2,001 kcal/day, median value of the population) (OR:2.495, 95%CIs:1.325-4.696, p = 0.005), particularly when they maintain negative balance between total energy expenditure (TEE) and TEI (TEE/TEI < 1) (OR:2.917, 95%CIs:1.451-5.864, p = 0.003). The contributions of APOA5-1131CC homozygotes to obesity risk in those who consume higher TEI were all significantly high regardless of percentage energy intake from dietary macronutrients. Whereas, no significant association was observed in those who consume lower TEI (<2,001 kcal/day). Additionally, serum levels of triglyceride, HDL-cholesterol and ApoA5 were associated with APOA5-1131T > C and TEI. These findings suggest that APOA5-1131 CC homozygotes may influence the susceptibility of the individual to obesity, particularly when they consume higher TEI, but the genetic effect may be attenuated when people maintain low or adequate energy intake.

    ABSTRACT: Since alterations in blood fatty acid (FA) composition by dietary lipids are associated with insulin resistance (IR) and related metabolic disorders, we hypothesized that serum phospholipid FA composition would reflect the early alteration of fasting glycemic status, even in people without metabolic syndrome (MetS). To examine this hypothesis, serum phospholipid FA, desaturase activities, fasting glycemic status, and cardiometabolic parameters were measured in study participants (n = 1022: 30-69 yrs, male: n = 527, female: n = 495, non-diabetics without disease) who were stratified into normal fasting glucose (NFG) and impaired fasting glucose (IFG) groups. Total monounsaturated FA (MUFA), oleic acid (OA;18:1n-9), dihomo-γ-linolenic acid (DGLA;20:3n-6), delta-9-desaturase activity (D9D;18:1n-9/18:0), and DGLA/linoleic acid (LA) (20:3n-6/18:2n-6) in serum phospholipids were significantly higher in IFG subjects than NFG controls. Study subjects were subdivided into four groups, based on fasting glucose levels and MetS status. Palmitoleic acid (16:1n-7) was highest in IFG-MetS and lowest in NFG-nonMetS subjects. OA and D9D were higher in IFG-MetS than in the other three groups. DGLA and DGLA/LA were higher in MetS than in nonMetS, regardless of fasting glucose levels. The hs-CRPs and 8-epi-PFG2α were higher in IFG than in NFG, regardless of MetS status. Oxidized-LDLs were higher in IFG-MetS than in the other three groups. Total MUFAs, OA, and D9D were positively correlated with HOMA-IR, fasting glucose, TG, hs-CRP, and 8-epi-PFG2α. Palmitoleic acid was positively correlated with TG and hs-CRP. Total MUFA, Lastly, OA, palmitoleic acid, and D9D were associated with early alteration of fasting glycemic status, therefore suggesting that these may be useful markers for predicting the risk of type 2 diabetes and cardiometabolic diseases.

    ABSTRACT: Nodular fasciitis (NF) is a common benign soft tissue tumor. However, F-FDG PET/CT findings of NF are limited. Two cases of NF are described that mimic soft tissue metastasis on F-FDG PET/CT during surveillance. F-FDG PET/CT is well documented in the surveillance of malignancy and increasing worldwide. There are growing chances of encountering FDG-avid nonmalignant soft tissue lesion. Nodular fasciitis could be considered as possible diagnosis on F-FDG PET/CT if a solitary well- circumscribed ovoid hypermetabolic soft tissue lesion is located in a muscle, intermuscular space, or adjacent tendon, especially in patients with a clinically low probability of tumor recurrence or metastasis.

    ABSTRACT: We report the successful melting and high-temperature liquid density measurements of grain-free single copper and silver crystals, using electrostatic levitation (ESL), for the first time. The melting of Cu and Ag using ESL has not been reported to date due to the unusual charge instability of these samples at high temperatures. We report here an improved levitation stability during heating when using single-crystal specimens. These results will aid the development and further study of industrially important Cu- and Ag-based materials, by indicating the key physical properties of their liquid phases.

    ABSTRACT: The c-Jun NH(2)-terminal kinase (JNK) is a critical determinant of obesity-associated inflammation and glucose intolerance. The upstream mechanisms controlling this pathway are still unknown. Here we report that the levels of the PB1 domain-containing adaptor NBR1 correlated with the expression of proinflammatory molecules in adipose tissue from human patients with metabolic syndrome, suggesting that NBR1 plays a key role in adipose-tissue inflammation. We also show that NBR1 inactivation in the myeloid compartment impairs the function, M1 polarization, and chemotactic activity of macrophages; prevents inflammation of adipose tissue; and improves glucose tolerance in obese mice. Furthermore, we demonstrate that an interaction between the PB1 domains of NBR1 and the mitogen-activated kinase kinase 3 (MEKK3) enables the formation of a signaling complex required for the activation of JNK. Together, these discoveries identify an NBR1-MEKK3 complex as a key regulator of JNK signaling and adipose tissue inflammation in obesity.

    ABSTRACT: Skeletal muscle degenerates progressively, losing mass (sarcopenia) over time, which leads to reduced physical ability and often results in secondary diseases such as diabetes and obesity. The regulation of gene expression by microRNAs is a key event in muscle development and disease. To understand genome-wide changes in microRNAs and mRNAs during muscle aging, we sequenced microRNAs and mRNAs from mouse gastrocnemius muscles at two different ages (6 and 24 months). Thirty-four microRNAs (15 up-regulated and 19 down-regulated) were differentially expressed with age, including the microRNAs miR-206 and -434, which were differentially expressed in aged muscle in previous studies. Interestingly, eight microRNAs in a microRNA cluster at the imprintedDlk1-Dio3 locus on chromosome 12 were coordinately down-regulated. In addition, sixteen novel microRNAs were identified. Integrative analysis of microRNA and mRNA expression revealed that microRNAs may contribute to muscle aging through the positive regulation of transcription, metabolic processes, and kinase activity. Many of the age-related microRNAs have been implicated in human muscular diseases. We suggest that genome-wide microRNA profiling will expand our knowledge of microRNA function in the muscle aging process.

    ABSTRACT: As aquatic biomass which is called "the third generation biomass", Laminaria japonica (also known as Saccharina japonica) consists of mannitol and alginate which are the main polysaccharides of algal carbohydrates. In this study, oleaginous yeast (Cryptococcus curvatus) was used to produce lipid from carbon sources derived from Laminaria japonica. Volatile fatty acids (VFAs) were produced by fermentation of alginate extracted from L. japonica. Thereafter, mannitol was mixed with VFAs to culture the oleaginous yeast. The highest lipid content was 48.30%. The composition of the fatty acids was similar to vegetable oils. This is the first confirmation of the feasibility of using macroalgae as a carbon source for biodiesel production.

    ABSTRACT: The tumor microenvironment plays a critical role in cancer progression, but the precise mechanisms by which stromal cells influence the epithelium are poorly understood. Here we show that p62 levels were reduced in the stroma of several tumors and that its loss in the tumor microenvironment or stromal fibroblasts resulted in increased tumorigenesis of epithelial prostate cancer cells. The mechanism involves the regulation of cellular redox through an mTORC1/c-Myc pathway of stromal glucose and amino acid metabolism, resulting in increased stromal IL-6 production, which is required for tumor promotion in the epithelial compartment. Thus, p62 is an anti-inflammatory tumor suppressor that acts through the modulation of metabolism in the tumor stroma.

    ABSTRACT: Eucommia ulmoides is one of the popular tonic herbs for the treatment of low back pain and bone fracture and is used in Korean medicine to reinforce muscles and bones. This study was performed to investigate the effects of E. ulmoides extract on longitudinal bone growth rate, growth plate height, and the expressions of bone morphogenetic protein 2 (BMP-2) and insulin-like growth factor 1 (IGF-1) in adolescent female rats. In two groups, we administered a twice-daily dosage of E. ulmoides extract (at 30 and 100 mg/kg, respectively) per os over 4 days, and in a control group, we administered vehicle only under the same conditions. Longitudinal bone growth rate in newly synthesized bone was observed using tetracycline labeling. Chondrocyte proliferation in the growth plate was observed using cresyl violet dye. In addition, we analyzed the expressions of BMP-2 and IGF-1 using immunohistochemistry. Eucommia ulmoides extract significantly increased longitudinal bone growth rate and growth plate height in adolescent female rats. In the immunohistochemical study, E. ulmoides markedly increased BMP-2 and IGF-1 expressions in the proliferative and hypertrophic zones. In conclusion, E. ulmoides increased longitudinal bone growth rate by promoting chondrogenesis in the growth plate and the levels of BMP-2 and IGF-1. Eucommia ulmoides could be helpful for increasing bone growth in children who have growth retardation. Copyright © 2014 John Wiley & Sons, Ltd.

    ABSTRACT: The aim of the present study was to identify the influence of vertebral fracture (VF) on the functional disability in patients with rheumatoid arthritis (RA). This study consecutively enrolled 100 female patients aged 50 yr or older with RA. All participants underwent lateral imaging of the thoracolumbar spine by simple radiography to identify any VFs. They also completed questionnaires via interview regarding demographics, medical history, and disease outcomes including functional disability. We used univariate analysis to evaluate associations between functional disability and VF, and made multivariate logistic regression models to test independent effect of the presence of VF, the number of VFs, and the severity of VF on functional disability. Among the 100 RA patients, 47 had at least one VF, but 34 of them were asymptomatic that they had experienced a fracture. The multiple VFs ≥ 3 (OR, 8.95; 95% CI, 1.77-44.15, P = 0.01) and moderate or severe VF (OR, 3.38; 95% CI, 1.26-9.04, P = 0.02) were related to disability in univariate analysis. The multiple VFs ≥ 3 (OR, 6.13; 95% CI, 1.02-36.94, P = 0.048) was associated with functional disability of RA patients after adjusting various confounders and it was mainly in walking and arising. The VF might be an important factor which affects functional disability in RA patients.
