Sistema de transferencia de datos en el instrumento TilePPr del proyecto TileCal
2017
El proyecto surge de la implementación del nuevo sistema de lectura de datos FELIX, que aprovecha los Transceptores Gigabit incorporados en las FPGA XC7VX485T y XC7VX690T del fabricante Xilinx. Estos transceptores se usan para establecer enlaces de datos a través de fibra óptica entre la FPGA del Pre-procesador del TileCal o TilePPr (XC7VX485T) y la placa electrónica que está conectada por PCIe al servidor local (XC7VX690T), por lo que el trabajo consiste en alcanzar los siguientes objetivos: a) Poner en marcha en la FPGA XC7VX485T del Pre-procesador o TilePPr la interfaz de transferencia de datos para que sea compatible con el nuevo sistema “Enlace de intercambio en el límite frontal” o FE…

FPGA Implementation of an Adaptive Filter Robust to Impulsive Noise: Two Approaches
2011
Adaptive filters are used in a wide range of applications such as echo cancellation, noise cancellation, system identification, and prediction. Its hardware implementation becomes essential in many cases where real-time execution is needed. However, impulsive noise affects the proper operation of the filter and the adaptation process. This noise is one of the most damaging types of signal distortion, not always considered when implementing algorithms, particularly in specific hardware platforms. Field-programmable gate arrays (FPGAs) are used widely for real-time applications where timing requirements are strict. Nowadays, two main design processes can be followed for embedded system design…
Distribution of risk factors, plasma lipids, lipoproteins and dyslipidemias in a small Mediterranean island: The Ustica Project
2003
Background and Aim: The populations of the Mediterranean area have a low incidence of cardiovascular disease (CHD). The aims of this paper are: 1) to present demographic data of the population of Ustica, a small island in the southern part of the Tyrrhenian sea that has reduced communications with the mainland and a diet presumably rich in fish; and 2) to evaluate the distribution of risk fa tors, plasma lipids, lipoproteins and dyslipidemias in this population. Methods and Results: We invited all of the free-living resident population aged more than 14 years (about 800 individuals) to participate in the study; 57 responded, for a participation rate of about 73%. The distribution of cardiov…
The influence of apo E phenotypes on the plasma triglycerides response to hormonal replacement therapy during the menopause
2001
Objective: To study the influence of apo E phenotype in plasma lipids, especially in triglycerides levels, in menopausal women receiving hormonal replacement therapy (HRT). Methods: One hundred and ten postmenopausal women were studied. Plasma total cholesterol (TC), HDL-C and triglycerides (TG) were measured before and after 3 months of HRT and the apo E phenotype was determined. According to the apo E phenotype the sample was divided into three groups: E2/E3 (n=28), E3/E3 (n=96) and E4/E3 (n=25). Results: In the pre-treatment state, higher plasma levels of TC and TC/HDL-C ratio were observed in women with phenotype E3/E4 (P<0.0001 and P<0.02, respectively), while higher plasma TG levels w…
Increased thioredoxin levels are related to insulin resistance in familial combined hyperlipidaemia
2015
BACKGROUND Thioredoxins (TRX) are major cellular protein disulphide reductases that are critical for redox regulation. Oxidative stress and inflammation play promoting roles in the genesis and progression of atherosclerosis, but until now scarce data are available considering the influence of TRX activity in familial combined hyperlipidaemia (FCH). Since FCH is associated with high risk of cardiovascular disease, the objective of the present study was to assess oxidative stress status in FCH patients, and evaluate the influence of insulin resistance (IR). MATERIALS AND METHODS A cohort of 35 control subjects and 35 non-related FCH patients were included, all of them nondiabetic, normotensiv…
Alterations in Lipid and Carbohydrate Metabolism in Patients with Classic Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency
2009
<i>Background:</i> Classic 21-hydroxylase deficiency (21HD) presents some traits of the metabolic syndrome. <i>Aim:</i> To characterize discrete alterations of lipid and carbohydrate metabolism in children and young adults with classic 21HD, which could predict early atherogenesis. <i>Patients and Methods:</i> Twenty-seven Caucasian patients with classic 21HD (4–31 years); 27 sex-, age- and BMI-matched controls. Clinical parameters, hormonal status and genotype were assessed in all patients. Lipid parameters, including relative (%) and absolute (mg/dl) small-dense low-density lipoproteins subfractions (sd-LDL) were measured in patients and controls. Oral …
Within subject variability of HDL-cholesterol in HIV-infected patients
2019
Background and objective: Within-subject variability of cardiovascular risk factors may influence the development of cardiovascular disease. We aimed to improve knowledge on HDL-cholesterol variability and its clinical significance in HIV-infected patients, a population at high risk of cardiovascular disease.Methods: This was a cohort study to quantify the variability of HDL-cholesterol between two consecutive visits and to determine factors associated with such variability, in a group of HIV-infected patients.Results: A total of 307 patients were included, mean ± standard deviation of their age was 45.1 ± 8.5 years, and 225 of them (73.3%) were male. The absolute difference (after squaring…
A study of insulin resistance using the minimal model in nondiabetic familial combined hyperlipidemic patients.
1998
The presence of insulin resistance in 20 male nondiabetic patients with familial combined hyperlipidemia (FCH) and 20 controls of similar age and body mass index (BMI) was investigated using the minimal model method modified by the administration of insulin and an oral glucose tolerance test. The peripheral sensitivity of insulin, expressed as the insulin sensitivity index (Si), was 1.91 ± 1.05 and 2.86 ± 1.19 × 10−4 · min−1 · mU/L in FCH patients and controls, respectively (P < .01), and the corresponding value for the peripheral utilization of glucose independently of insulin (Sg) was 1.70 ± 1.13 in FCH patients and 2.35 ± 0.60 × 10−2 · min−1 in controls (P < .02). In the FCH group, the S…
Metabolic changes induced by combined prolonged exercise and low-calorie intake in man
1984
Thirteen middle-aged women and 10 men walked 344 km during 7 days. The daily walking distances were 57, 53, 67, 53, 41, 36, and 37 km at an average speed of 3.5 km X h-1. During the hike the subjects drank water, mineral drinks, and juices ad libitum. Except for some natural products, no food intake was allowed. During the hike the body weight and serum protein concentration of the subjects decreased by about 7%, on average. Serum triglyceride and total cholesterol decreased drastically, about 30-40% during the hike, but HDL-cholesterol showed a tendency to increase, giving a 40% increment in HDL/total cholesterol ratio. Serum free fatty acids rose 1.5-2 times above the starting level. Seru…
