High density lipoproteins (HDL) promote the efflux of excess cholesterol from peripheral tissues to the liver for excretion. This ability is responsible for the most relevant anti-atherogenic effect of HDL. The ability of HDL to promote cholesterol efflux results also in the modulation of a series of responses in the immune cells involved in atherosclerosis, including monocyte-macrophages, B an...

The purpose of this study was to examine the effectiveness of brisk walking as a means of improving endurance fitness and influencing serum lipid and lipoprotein variables in previously sedentary women. Walkers (n = 10, mean (s.e.m.) age 47.3(2.0) years) followed a programme of brisk walking (mean(s.e.m.) speed 1.76(0.03) m s-1) for 12 weeks, after which the training stimulus was withdrawn. Con...

BACKGROUND: Currently, there are a lack of investigations that have examined the effect of participating in a comprehensive cardiac rehabilitation program on quality of life and physiological measures in women of different ages. The purpose of this investigation was to examine the effect of participating in a comprehensive cardiac rehabilitation program on quality of life, exercise tolerance, b...

The effect of dietary magnesium (Mg) on the development of atherosclerosis in cholesterol-fed rabbits was investigated. Male New Zealand White rabbits (n = 31) were placed on five kinds of diets: regular, 1% cholesterol, and 1% cholesterol diets supplemented with either 300, 600, or 900 mg (as Mg) of Mg sulfate. The regular and 1% cholesterol diets contained 400 mg of Mg per 100 g. Each rabbit ...

We introduce and develop models for very high density physical goods storage systems, which are characterized by sometimes having to move interfering items in order to gain access to desired items. We describe a simple but effective algorithm to densely fill rectangular storage spaces, subject to a constraint on the number of interfering items. We also prove an upper bound on storage density fo...

The Through Silicon Via (TSV) process developed by Silex provides down to 30 μm pitch for through wafer connections in up to 600 μm thick substrates. Integrated with MEMS designs it enables significantly reduced die size and true "Wafer Level Packaging" features that are particularly important in consumer market applications. The TSV technology also enables integration of advanced interconnect ...

Since the introduction of optical data storage systems in the 1970s, we have observed a stepwise increase in their storage capacity using the same means for resolution improvement as in classical microscopy and optical lithography, namely, a reduction in the source wavelength and an increase in the numerical aperture of the imaging optics. In this paper we briefly address the historical develop...

Typical atrial flutter (AFL) is a common arrhythmia that is responsible for about 10% of all hospitalizations for supraventricular tachycardia in adults. The reentrant circuit through the cavotricuspid isthmus is located in the right atrium, and the left atrium is then activated passively. Cavotricuspid isthmus radiofrequency (RF) ablation is considered a first-line therapy to achieve rhythm co...

The high parton density regime in deep inelastic electronproton (nucleus) scattering is characterized by small values of the Bjorken variable x = Q/s, where Q is the momentum transfer and √ s is the center of mass energy, and represents the challenge of studying the interface between the perturbative and nonperturbative QCD, with the peculiar feature that this transition is taken in a kinematic...
