  • Uncoupling proteins (UCPs) are transmembrane proton transporters present in the mitochondria. In UCPs. UCP1 and UCP3 play an important role in adaptive thermogenesis by uncoupling mitochondrial oxidation of substrates from ATP synthesis. PPARg coactivator 1(PGC-1) regulates transcriptional activity of PPARg and other nuclear receptors and controls the expression of UCPs. (omitted)

  • When an issuing bank issues a documentary credit, it must decide if the reimbursement will be a direct or simple or a bank-to-bank reimbursement. This decision is based on the bank that is nominated to pay, incur a deferred payment undertaking, accept drafts or negotiate. If an issuing bank decided bank-to-bank reimbursement, it must include the information in the credit instructing the nominated bank on how to obtain reimbursement. This instruction includes the name of the reimbursing bank, an indication that the reimbursement is subject to the Uniform Rules for Bank-to-Bank Reimbursements Under Documentary Credits ('URR'), ICC Publication 525 and any additional information that affects the nominated bank's ability to receive reimbursement. Until recently, reimbursements were the subject of outline regulation by Article 19 of the Uniform Customs and Practice for Documentary Credits ('UCP') and national law. Now, however, the International Chamber of Commerce has drafted URR, designed to emulate the harmonization of rules governing documentary credits achieved by the UCP. The URR are complementary to the UCP, which they are not intended to override or change. They became effective on July 1, 1996. The purpose of this study is to promote understanding on the Uniform Rules for Bank-to-Bank Reimbursements under Documentary Credits. In this paper, I studied the following subjects:(1) Bank-to-Bank Reimbursements tranaction under Documentary Credits, (2) Meaning of the URR's promulgation, (3) Analysis on the URR's Article. (1) General provisions and definitions, (2) Liabilities and responsibilities, (3) Form and notification of authorisations, amendments and claims, (4) Miscellaneous provisions.

  • The present study investigated the effect of Sinetrol-XPur (polyphenolic Citrus spp. and Paullinia cupana Kunth dry extract) and defined the action mode for cyclic adenosine monophosphate (cAMP)-dependent uncoupling protein (UCP)-2 activation. Leptin-deficient obese mice were treated with two different doses, 100 mg/kg body weight (BW) and 300 mg/kg BW of each AIN93G supplement, for 7 weeks. Treatment of obese mice with both low and high doses of Sinetrol-XPur significantly reduced body weight gain compared to control obese mice. White adipose tissue weight of mice was reduced by 30.96% in high dose-supplemented groups. Serum total cholesterol and triglyceride were reduced by a high dose of Sinetrol-XPur by 20.02% and 30.96%, respectively. Serum level of high density lipoprotein (HDL) was significantly increased by treatment with both doses, as the ratio of HDL to low density lipoprotein increased by 138.78% and 171.49%, respectively. Regarding expression of biochemical factors related to lipid metabolism, fatty acid synthase significantly decreased and UCP-2 increased upon treatment with a high dose of Sinetrol-XPur, but there was no significant difference in lipoprotein lipase and hormone-sensitive lipase. To define cellular mechanism, intracellular cAMP levels in 3T3-L1 adipocytes significantly increased in a dose-dependent manner over the range of $50{\sim}250{\mu}m/mL$. The phosphodiesterase (PDE) inhibitor 3-isobutyl-1-methylxanthine clearly blocked cAMP, suggesting that Sinetrol-XPur promotes lipolysis of adipocytes through inhibition of cAMP-dependent PDE, resulting in induction of cAMP response element binding protein and UCP-2. These results suggest that Sinetrol-XPur supplementation is a viable option for reducing body weight and fat by improving serum lipid profiles and genetic expression of lipid metabolic factors, especially activation of cAMP-dependent UCP-2.

  • A non-documentary conditions is a condition contained in the credit without reference to the presented document in compliance therewith, thereby causing many problems to all parties involved in letter of credit transactions. The purpose of this study is to examine the regulations on the non-documentary conditions under Uniform Customs and Practice for Documentary Credits: UCP, International Standby Practices: ISP98, United Nations Convention on Independent Guarantee and Stand-by Letters of Credit: CIGSLC and Uniform Commercial Code: UCC and also the opinions on the effect of non-documentary conditions through the analysis of several cases on the non-documentary conditions. The result of this study can be summarized as follows: First, UCP, ISP98, CIGSLC and UCC stipulate that banks will deem non-documentary conditions as not stated and will disregard them. Second, courts used to permit the effect of non-documentary conditions. Finally, all parties should not attempt to put in any non-documentary conditions in order to prevent disputes on the effect of non-documentary conditions.

  • One of the important issues facing current letter of credit practice is the effect of nondocumetary conditions. A nondocumentary condition is a condition contained in the credit without stating the document to be presented in compliance therewith, so nondocumentary condition must be ascertained by reference to factual matters rather than by review of a tendered document. This study attempts to examine the regulations in UCP, ISP98 and UCC on the nondocumetary conditions and the opinions on the effect of nondocumetary conditions and to analyze various cases on the effect of nondocumetary conditions. The results of this study can be summarized as follows. Firstly, UCP, ISP98 and UCC stipulate that banks will deem nondocumetary conditions as not stated and will disregard then So the legal standards for nondocumetary conditions have established. Secondly, courts used to permit the effect of nondocumetary conditions on the basis of the Wichita rule, party autonomy. Thirdly, issuing banks and applicants should not attempt to put in any nondocumetary conditions in order to prevent disputes on the effect of nondocumetary conditions.

  • Beneficiary must present all documents stipulated in the Credit. If the documents conform in all respects with the terms and conditions of the Credit, beneficiary has a right to payment from an issuing or confirming bank. And banks must examine all documents presented by beneficiary for taking up the documents. If the documents appear on their face not to be in compliance with the terms and conditions of the Credit, banks may refuse to take up the documents. But standard for compliant documents with the terms and conditions of the Credit in the UCP or Section 5 of UCC is unclear. Because UCP Article 13(a) provides merely that banks must examine all documents stipulated in the Credit ${\cdots}$ to ascertain whether or not they appear, on their face, to be compliance with the terms and conditions of the Credit. ${\cdots}$ Documents which appear on their face to be inconsistent with one another will be considered as not appearing on their face to be in compliance with the terms and conditions of the Credit. Also UCC Section 5-108(a) provides merely that. ${\cdots}$ an issuer shall honor a presentation that, ${\cdots}$ appears on its face strictly to comply with the terms and conditions of the letter of credit. All problems are not resolve with easy by these regulations. Accordingly, I examined requirements for compliant documents with the terms and conditions of the Credit on the basis of the UCP and cases. To analyse this, I divided into three requirements ; (1) Completeness, (2) Regularity, (3) Linkage.

  • Objectives: The aim of the study was to investigate the efficacy of Boiogito for obesity. We examined the efficacy of Boiogito for obese patients and we expected the reaction of Boiogito would vary according to the single nucleotide polymorphism(SNPs). Methods: 111 subjects(body mass index${\geq}25m/kg^2$) were recruited and randomized to receive Boiogito(n=55) or Placebo(n=56) for 8weeks. Anthropometric factors, serum lipid profile, glucose, blood pressure(BP), pulse rate, resting metabolic rate and Korean version of obesity-related quality of life(KOQOL) scale measured at baseline and 8weeks. SNPs(${\beta}3$-adrenergic receptor(ADRB3), G protein ${\beta}3$(GNB3), peroxisome proliferator activated receptor gamma 2 gene(PPAR-${\gamma}2$), uncoupling protein(UCP2)) were conducted at baseline. Adverse reactions and safety outcome variables were also checked during trials. Results: Both groups showed significant improvement on obesity after treatment. Boiogito group decreased triglyceride than did control group and improved KOQOL. Boiogito showed a significant higher efficacy in C/T and T/T genotype of GNB3 gene / in Trp64 and Arg64 genotype of ADRB3 gene / in D/D genotype of UCP2 gene / in Pro/Pro genotype of PPAR-${\gamma}$ gene. Conclusions: Boiogito promoted obesity indexes without severe adverse reactions and proved its safety. Pharmacogenetical studies of Boiogito on obesity could be a effective method for the individualized treatment and prevention of obesity.

  • Objective : The aim of the study was to investigate the effect of Acanthopanax senticocus(AS) herbal acupuncture on the metabolic syndrome in high-fat diet fed mice. Methods : ICR mice were fed with high-fat diet to induce the metabolic syndrome. During the inducement of the metabolic syndrome, the groups were treated with AS herbal acupuncture with different concentrations(125mg/kg, 250mg/kg and 500mg/kg) to the point of Sinsu(BL23) everyday for 5 weeks. Thereafter, body weight, feed efficiency ratio, blood pressure, blood glucose, insulin level, insulin resistance, oral glucose tolerance test(OGTT), lipid profile(TG, TC, HDL-C, LDL-C, NEFA), mass of liver, histology of white adipose tissue(WAT) and brown adipose tissue(BAT), and expression of GLUT-4 and UCP-1 mRNA were measured. Results : The risk factors of metabolic syndrome such as obesity, non-insulin dependent diabetes mellitus(NIDDM), insulin resistance, hypertension, dyslipidemia were aggravated by high-fat diet for 5-weeks. AS herbal acupuncture inhibited the development of weight gain, hyperglycemia, hyperinsulinemia, insulin resistance, hypertension, dylipidemia and expression of GLUT-4 in WAT and UCP-1 mRNA in BAT, and also improved oral glucose intolerance and distribution of adipose tissue.

  • Capsaicin is a pungent component of red pepper, which is widely consumed as food adjuncts. The present study was performed to investigate anti-obesity effects of capsaicin in diet-induced obese rats. Male Sprague-Dawley rats (n=14) were fed with a high-fat diet (Control) or high-fat diet containing 0.016% capsaicin (w/w) (Capsaicin) for 8 weeks. The final body weight and the mass of white adipose tissue were significantly lower in capsaicin supplemented group compared to control. Dietary capsaicin ameliorated lipid profiles with decrease in the plasma concentrations of triglycerides and total cholesterol, and decrease in the levels of total lipids and triglycerides in the liver. Activity of glycerol-3-phosphate dehydrogenase (GPDH), an indicator of triglyceride biosynthesis in white adipose tissue, decreased by 35% in the group supplemented with capsaicin. However, consumption of capsaicin increased the expression of uncoupling protein 2 (UCP2) in white adipose tissue, which is related to energy consumption. Our data suggests that capsaicin may reduce body weight and fat accumulation in high fat diet-induced obese rats. These effects may be mediated, at least partially, by the upregulation of UCP2 gene expression and its ability to inhibit GPDH activity.
