Scaling of CMOS technology into the deep submicron regime gives rise to process variability, which in turn compromises circuit yield. One of the main sources of variability is random dopant fluctuation (RDF) in the channel. Fully Depleted Silicon on Insulator technology has been proposed as a promising alternative to bulk CMOS, due to it’s undoped channel which reduces RDF, as well as due to it...

Background To determine the prevalence of Peripheral Arterial Disease (PAD) and associated risk factors in patients undergoing amputation at the Korle Bu Teaching Hospital (KBTH), Accra, Ghana. Objectives A cross- sectional study of all patients undergoing lower extremity amputation at the Department of Surgery, KBTH. Materials A coded questionnaire was used to ascertain risk factors for PA...

BACKGROUND Outpatient ascertainment of peripheral artery disease (PAD) is rarely considered in the measurement of PAD clinical burden; therefore, the clinical burden of PAD likely has been underestimated while contributing to a decreased awareness of PAD in comparison to other circulatory system disorders. METHODS AND RESULTS The purpose of this study was to estimate the age-standardized annu...

Peripheral arterial disease (PAD) patients have augmented blood pressure increases during exercise, heightening their cardiovascular risk. However, it is unknown whether patients have exaggerated renal vasoconstriction during exercise and if oxidative stress contributes to this response. Eleven PAD patients and 10 controls (CON) performed 4-min mild, rhythmic, plantar flexion exercise of increa...

A complementary metal–oxide semiconductor (CMOS) single-stage cascode low-noise amplifier (LNA) is presented in this paper. The microwave monolithic integrated circuit (MMIC) is fabricated using digital 90-nm silicon-on-insulator (SOI) technology. All impedance matching and bias elements are implemented on the compact chip, which has a size of 0.6 mm 0.3 mm. The supply voltage and supply curren...

Current methods for determining the fibrogenicity of substances are based on relatively long term exposures of animals to the substance and the evaluation of morphological changes occurring in the lung. The use of inhalation chambers, which produce a more physiological environment, suffer from the need for particularly long exposure times (1-3 years). The present study describes a technique usi...

CONTEXT Peripheral arterial disease (PAD) is a manifestation of systemic atherosclerosis that is common and is associated with an increased risk of death and ischemic events, yet may be underdiagnosed in primary care practice. OBJECTIVE To assess the feasibility of detecting PAD in primary care clinics, patient and physician awareness of PAD, and intensity of risk factor treatment and use of ...

Silicon has beneficial effects on growth, yield and improvement of the tolerance of some plants against biological and non-biological stresses. In order to study the effects of different concentrations of silicon (as Na2SiO3) on Iranian borage (Echium amoenum Fisch & C.A. mey), three levels of silicon (0, 0.2, 0.7 mM as Na2SiO3) and two levels of salinity (0 and 100 mM as NaCl) and two silicon-...

BACKGROUND Limited data exist on the prevalence of peripheral arterial disease (PAD) among ethnically diverse populations. Our objectives were to assess the prevalence of PAD in a multiethnic national sample and examine risk factor control and allostatic load (a marker of dysregulation of the inflammatory, metabolic, and cardiovascular systems) by race/ethnicity among individuals with PAD. ME...

Hypertension is a common risk factor for peripheral arterial disease (PAD). Guidelines suggest treating PAD patients to a blood pressure <130/80 mm Hg; therefore, our objective was to explore whether attainment of this target blood pressure is associated with improved outcomes. We performed a post hoc analysis of the INternational VErapamil-SR/Trandolapril STudy, a randomized clinical trial, wh...
