—A 12 bit 2.9 GS/s current-steering DAC implemented in 65 nm CMOS is presented, with an 3 60 dBc beyond 1 GHz while driving a 50 load with an output swing of 2.5 ppd 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(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)
—A 40 nm CMOS digital-to-analog converter (DAC) based multimode transmitter (MMTX) is presented. The transmitter can be operated in either narrow-or 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 Endothelial nitric oxide synthase produces nitric oxide which is involved in many physiologic regulatory functions. Variable number of tandem repeats in intron 4 of endothelial nitric oxide synthase gene are reported to be associated with blood pressure regulation. Nitric oxide is involved in regulation of cardiomyocyte genes but it is not known(More)
OBJECTIVE The aim of this pilot study was to determine clinical and laboratory factors that predict amputation surgery and to evaluate the predictive value of soluble CD14 (sCD14), interleukin-6 (IL-6), and procalcitonin (PCT) in patients with diabetic foot ulcers (DFUs). METHODS Twenty-seven (20 males, 7 females) Diabetic Foot Ulcers (DFU) patients(More)
Aim: To compare three methods for measurement of blood HbA1c as to reliability, ease and time consumption. " Method: Measurements of HbA1c were made in blood from 120 patients with pre-diabetes and diabetes using a turbidimetric inhibition immunoassay (TINIA), which also required measurement of total hemoglobin, a particle-enhanced immunoturbidimetric assay(More)
BACKGROUND Unconjugated bilirubin (UCB) plays a protective role in coronary artery disease. Red cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are inflammatory biomarkers and higher levels are related to atherosclerosis and adverse cardiovascular events. AIM We aimed to investigate the relation(More)
The speed of Ethernet over copper cables has steadily increased by a factor of 10,000 over the last four decades, from 1Mb/s in the earliest Ethernet implementations to 10Gb/s in recent systems. This paper describes the design considerations on all levels of the 10GBASE-T design hierarchy that form the basis for the implementation of highly power-efficient(More)
