The incidence of cardiovascular disease increases rapidly after 40's. The thickness of the epicardial adipose tissue was measured to analyze the risk factors affecting the thickness change. We present the cut off value for the epicardial adipose tissue thickness for high impacted variables. For the study, 547 patients underwent echocardiography, epicardial adipose tissue thickness, body mass index, abdominal subcutaneous fat thickness and diabetes mellitus were used as analytical variables. As a result, multiple regression analysis of age group showed that diabetes mellitus was highly influential in all age group, so we could predict the cut off value for the epicardial adipose tissue thickness for diabetes mellitus. As a result of ROC curve analysis, cut off value of 7.44 mm was obtained with sensitivity of 79.6% and specificity of 60.6% for diab etes variab le. Logistic regression analysis b ased on this value showed that the risk for diab etes increased 6 times with each increase in the thickness of the epicardial adipose tissue. Among the various obesity indexes, epicardial adipose tissue is used as an important index especially to prevent the risk of cardiovascular disease. Therefore, we suggest that the use of echocardiography as a routine screening method for the prevention of cardiovascular disease and metabolic syndrome, which is rapidly increasing in patients over 40's age, will enable more effective monitoring. Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.

Left ventricular diastolic dysfunction is mostly observed in patients with cardiac disease, such as myocardial ischemia or LVH, but linking is usually observed in healthy people without heart disease. Evaluation of left ventricular diastolic failure in normal cardiac output(systolic function) conditions can affect the progress and prognosis of heart failure. The direct relevance to the epicardial adipose tissue metabolism in cardiovascular engine for generating a bioactive moleculer, which leads to dysfunction of the later had a direct effect on myocardial heart. The purpose of this study is to measure the thickness of the epicardial adipose tissue was to study the relevance of the assessment of diastolic dysfunction in systolic function in normal conditions. Results epicardial adipose tissue thickness and diastolic dysfunction was analyzed to have a high correlation in a statistically significant level. In particular, the epicardial adipose tissue thickness measured at the measuring section EAT2 and diastolic function evaluation E' was found to have a high correlation. Thus epicardial adipose tissue thickness variation is believed can be used as a predictor to evaluate the left ventricular diastolic dysfunction.

Epicardial adipose tissue(EAT) is metabolically active endocrine organ that secretes several hormones in fat thickness is a risk factor for cardiovascular disease and metabolic disorders. This study was to measure and then using ultrasound epicardial adipose tissue thickness, abdominal subcutaneous fat thickness in the target group correlates and general blood properties and characteristics, and presents a local thickness for prediction of metabolic disorders. Results epicardal adipose tissue of the average thickness measured in each of the subjects was 8.890mm, 4.783mm, 4.777, 6.147mm in each section. Showed the epicardial adipose tissue in correlation with the average thickness of the risk factors age, BMI, SBP, LDH, LDL, TC is a positive correlation relationship(p<0.05) in each section. In particular, the thickness of the metabolic disorders epicardial adipose tissue thickness, abdominal subcutaneous compared to subjects that do not have the risk subjects with a risk factor for fat significantly higher(p<0.05). It showed the most reliable that can be cut-off value of 8.950mm obtained with 66.7 % sensitivity and 80 % specificity for predicting the risk of metabolic disorders.

Postmenopausal women are at increased risk for osteoporosis and obesity due to changes in hormones. The relationship between osteoporosis and body weight is known, and its relation with body fat mass is discussed. The purpose of this study was to evaluate the bone mineral density(BMD) changes of epicardial adipose tissue(EAT) and abdominal subcutaneous fat. The subjects of this study were 160 postmenopausal women who underwent BMD and echocardiography. The thickness of the epicardial adipose tissue was measured in three sections and the BMD were meassured according to the diagnostic criteria. The results of this study that age increase the risk of osteoporosis increases, and as the weight and BMI decrease, the risk of osteoporosis increases(p<0.05). The relationship between changes in bone mineral density and adipose tissue in postmenopausal women, increased epicardial adipose tissue was negatively correlated with the bone mineral density(p<0.05). conversely, increased abdominal subcutaneous fat thickness was positively correlated with bone mineral density(p<0.05). In other words, the effect of bone mineral density on the location of adipose tissue was different. If Echocardiography is used to periodically examine changes in the thickness of the epicardial adipose tissue, it may be prevented before proceeding to osteoporosis.

Phosphorylation and glycosylation are two of the most important and widespread post-translational modifications (PTMs) in an organism. Proteomics analysis of the PTMs has been challenged by low stoichiometry of the modified proteins and suppression effects by high abundance proteins, typically no-functional house-keeping proteins. In this study, a novel method was applied for not only isolating PTM peptides from intact peptides but also concurrently characterizing of glyco- and phosphoproteome using electrostatic repulsion hydrophilic interaction chromatography (ERLIC) packed with silica coated by crosslinked polyethyleneimine. For 2 mg tryptic digest of mouse proteome of epicardial adipose tissue with fat diet, 802 N-glycosylated peptides of 316 glycoproteins and 159 phosphorylated peptides of 75 phosphoproteins were identified using HPLC chip/quadrupole time-of-flight (Q-OF) tandem mass spectrometer.
