DIABETES RESEARCH AND CLINICAL PRACTICE

Aims: : The aim of this study was to determine serum NT-proBNP and plasma Hcy levels and to explore the relationship between serum NT-proBNP and plasma Hcy levels in type 2 diabetic patients with and without asymptomatic LVDD. Methods: : NT-proBNP and Hcy levels were measured 31 patients with type 2 diabetes mellitus. According to echocardiographic data, diabetic patients were divided into two groups: normal LV function or LV diastolic dysfunction. Results: : Serum NT-proBNP levels in diabetic patients with LVDD were significantly higher than in diabetic patients with normal LV function and controls. The area under the receiver-operating characteristic (ROC) curve for NT-proBNP to separate normal vs. diastolic dysfunction was 0.96 in type 2 diabetic patients. Plasma Hcy levels were significantly higher in both diabetic groups than in controls. Positive correlation was noted between NT-proBNP and Hcy levels in diabetic patients with LVDD (r = 0.881, p = 0.0001). Conclusions: : The correlation between elevated NT-proBNP and Hcy levels in diabetic patients with LVDD suggest an association between homocysteinemia and increased NT-proBNP secretion. Our data indicate that NT-proBNP may be a simple screening tool to select diabetic patients with LVDD requiring further examination with echocardiography. (C) 2009 Elsevier Ireland Ltd.

ME-SERIES; GREAT CRASH; TESTS

High-yield bonds hold a particularly unique space in the debt market. From many aspects, literature suggests these assets to behave more like stocks than bonds. Given the significant similarities between the high-yield bond and stock markets, it is expected for these markets to be similarly affected by certain outside factors. Some shocks, including the ones from energy markets, are known to impact the entire stock market and not just related company shares. Since high-yield bond portfolios include some amount of energy company debt, the recent volatility in energy prices has been particularly concerning to market participants. However, the question of whether price and volatility shocks only impact energy company bonds or the entire high-yield bond market - as they do with the stock market - still remains unanswered. This study attempts to address that question by exploring the dynamic relationships between the high-yield bond and energy markets. Price transmission tests, which account for gradual structural shifts, suggest oil and ethanol markets significantly impacting the high-yield bond market. Furthermore, volatility tests find uni-directional volatility transmitting from energy markets to the high-yield bond market. (C) 2017 Elsevier B.V. All rights reserved

causality and volatility transmission analysis

According to literature, oil price shocks and volatility can have sector-specific impacts in the market While these studies include most asset groups, the dynamic relationship between the oil market and Real Estate Investment Trusts (REITs) has not been tested. This study examines the role of oil price shocks and volatility on six REIT categories: Residential, Hotel, Healthcare, Retail, Mortgage and Warehouse/Industrial REITs for the January 2005-December 2013 period. In addition, a new causality approach is proposed by augmenting the Toda-Yamamoto method with a Fourier approximation. This approach is capable of capturing gradual or smooth shifts and does not require a prior knowledge regarding the number, dates, and form of structural breaks. The so-called Fourier Toda-Yamamoto causality (mean spillover) test finds uni-directional causality running from oil prices to all REITs, except for the mortgage REITs. In the latter case, the causality is reversed. In addition, the relatively new and simple causality-in-variance test shows that there is bi-directional volatility transmission between the oil market and all REITs. Our results have important implications for REIT managers and investors. (C) 2016 Published by Elsevier B.V

Favism

The term 'favism' is used to indicate a severe reaction occurring on ingestion of foodstuffs consisting of or containing the beans of the leguminous plant Vicia faba (fava bean, broad bean). Within 6-24. h of the fava bean meal, the reaction manifests itself with prostration, pallor, jaundice, and dark urine. These signs and symptoms result from (sometimes massive) destruction of red blood cells (RBCs; acute hemolytic anemia), triggered by certain glucosides (divicine and convicine) present at high concentrations in the fava beans. These glucosides cause severe damage to RBCs only if the cells are deficient in the enzyme glucose-6-phosphate dehydrogenase (or G6PD); therefore, favism occurs only in people who have inherited G6PD deficiency. Favism is more common and more life-threatening in children (usually boys) than in adults; however, once the attack is over, a full recovery is usually made. In a person who is G6PD deficient, favism can recur whenever fava beans are eaten, although whether this happens or not is greatly influenced by the amount of beans ingested and probably by many other factors. From the public health point of view, it has been proven that favism can be largely prevented by screening for G6PD deficiency and by education through the mass media. © 2013 Elsevier Inc.

INVESTIGATION of the AIR QUALITY CHANGE EFFECT on GNSS SIGNALS

4th International GeoAdvances Workshop - GeoAdvances 2017: ISPRS Workshop on Multi-Dimensional and Multi-Scale Spatial Data Modeling -- 14 October 2017 through 15 October 2017 -- -- 131995Air pollution is the most important environmental problem in Zonguldak city center. Since bituminous coal is used for domestic heating in houses and generating electricity in thermal power plants, particulate matter (PM10) is the leading air pollutant. Previous studies have shown that the water vapor in the troposphere is responsible for the tropospheric zenith delay in Global Navigation Satellite System (GNSS) measurements. In this study, data obtained from the ZONG GNSS station from Türkiye Ulusal Sabit GNSS Al (TUSAGA-Active network) in the central district of Zonguldak province, processed with GIPSY-OASIS II and GAMIT/GlobK software using the VMF1 mapping function, which is developed previously and considered to be the most accurate model. The resulting values were examined separately in terms of software. The meteorological parameters obtained from the Turkish State Meteorological Service and the air pollution values obtained from the Ministry of Environment and Urban Planning were analyzed and the zenith delay values were compared. When wet zenith delays of different days with different amounts of PM10 concentrations were examined in succession and under the same meteorological conditions, differences in the range of 20–40 mm on ZTD were observed. © Authors 2017

Oil Prices and Monetary Policy in Emerging Markets: Structural Shifts in Causal Linkages

This study tests the causal relationships between oil prices and monetary policy for the emerging markets (Brazil, India, Indonesia, South Africa, and Turkey). In particular, we explore the role of exchange rates, inflation, and interest rates. First, we utilize the commonly used Toda–Yamamoto causality framework and later augment the model to account for structural shifts—including gradual/smooth shifts. The empirical findings show that (i) accounting for gradual structural shifts matter for the causal linkages between oil prices and the monetary policy variables and (ii) employing a bivariate or multivariate frameworks is not important (with few exceptions) as much as controlling for structural breaks in these causal linkages. ©, Copyright © Taylor & Francis Group, LLC

markets

This study analyzes price and volatility transmissions between nineteen real estate investment trusts (REITs) and the oil markets. The REITs data represents a variety of countries at different stages of their development and the expanded analytical approach includes accounting for structural shifts as gradual processes - as opposed to strictly abrupt processes typically assumed in the literature. Oil prices are found to primarily predict REITs prices in mature REITs markets, but the feedback from REITs to oil prices is weak. From the perspective of volatility, strong evidence of bidirectional transmission in majority of the markets is observed. Our results are in general robust to a shorter common sample period of the various countries. This study further demonstrates the importance of accounting for gradual (smooth) structural shifts for price transmission analysis. (C) 2020 Elsevier B.V.
