A 12 bit 2.9 GS/s current-steering DAC implemented in 65 nm CMOS is presented, with an dBc beyond 1 GHz while driving a 50 load with an output swing of 2.5 and dissipating a power of 188 mW. The SFDR measured at 2.9 GS/s is better than 60 dB beyond 340 MHz while the SFDR measured at 1.6 GS/s is better than 60 dB beyond 440 MHz. The increase in performance(More)
A 40 nm CMOS digital-to-analog converter (DAC) based multimode transmitter (MMTX) is presented. The transmitter can be operated in either narrowor wideband applications. It has a maximum 2.2 GHz signal bandwidth and exhibits an in-band IM3 of less than 58 dBc. The MMTX consists of a current-steering DAC with digital sinc equalization and rolloff(More)
BACKGROUND Chronic kidney disease (CKD) is associated with increased risk for cardiovascular (CV) disease and is also associated with elevated uric acid, which is emerging as a nontraditional CV risk factor. We therefore evaluated uric acid as a risk factor for CV disease in subjects presenting to nephrologists with CKD who were not on medications known to(More)
Since the recent publication of the World Health Organization brain tumour classification guidelines in 2007, a significant expansion in the molecular understanding of glioblastoma multiforme (GBM) and its pathological as well as genomic variants has been evident. The purpose of this review article is to evaluate the histopathological, molecular and(More)
Glioblastoma multiforme (GBM) is an aggressive grade IV astrocytoma with a 1-year median survival rate despite current treatment modalities. A thorough understanding of the vast genetic aberrations and signaling pathways involved in gliomagenesis as well as heterogeneous clinicopathological presentation remains elusive. The recent discovery of microRNAs(More)
BACKGROUND Obesity and Helicobacter pylori (H. pylori) are important because of the problems they lead and their frequency of occurrence. In this study, we aimed to find out the prevalence of H. pylori infection and the relationship between obesity and H. pylori in obese and normal weight subjects. METHODS A total of 214 subjects were (103 obese (71 male,(More)
OBJECTIVE Smoking and cholesterol levels are two significant causes of atherosclerosis. Mean platelet volume (MPV) is an index of platelet activation. Only limited numbers of studies showing the effect of smoking on platelet function are published. Even less studies exists regarding the effect of smoking on platelet function in young healthy population. The(More)
RATIONALE, AIMS AND OBJECTIVES Standardizing arterial blood pressure (BP) measurement is difficult because of different performers like doctor or pharmacy employee. We investigated the reliability between different BP measurement methods. METHODS The study was conducted in an internal medicine service with 160 patients in Ankara, Turkey. First, the(More)
Neutrophils and lymphocytes (N/L) ratio and carotid intima-media thickness (C-IMT) value have been studied as new predictors of cardiovascular risk. We aimed to investigate N/L ratio and C-IMT value in patients with cardiac syndrome X (CSX) and compare patients with coronary artery disease (CAD) and normal participants. A total of 288 participants were(More)
