Using a theoretical model of smooth muscle cell from rat mesenteric arterioles, we investigated calcium dynamics in normal and hypertensive vascular wall. The model incorporated a detailed description of plasma membrane, cytosol and intracellular stores. Inhibition of Na + -K + pump (NaK) simulated the effect of ouabain in salt sensitive hypertension. The inhibition caused intracellular sodium ...

One of the most important technical problems in reliable multicast protocol is reducing redundant feedback information, e.g. NAKs, to avoid feedback implosion. A number of feedback suppression mechanisms have been proposed to deal with this problem. In the MBONE, which is a virtual multicast network and makes multi-point communication across the Internet feasible, the source link, the links dir...

In this paper, we investigate how packet level redundancy mechanisms could be combined with ARQ (Automatic Repeat reQuest) to achieve scalable reliable mobile multicast transmissions. We consider three redundancy mechanisms. The first one called FEC-based mechanism is that redundant packets are achieved by FEC (Forward Error Correction) encoding. The second type called Replicate-based mechanism...

PURPOSE Recent evidence suggests that taurine and myoinositol may serve as organic osmolytes in a number of cells, including lens and retinal pigment epithelia, but the mechanism for their increased accumulation in response to hypertonic stress is not known. To assess whether NaK ATPase contributed to the elevated levels of taurine and myoinositol in cells exposed to hypertonic media, we measur...

Existing reliable multicast protocols are designed to perform well in wired networking environments. However, in mobile networking environments, these reliable mobile multicast protocols are not optimal as they do not take into account the limitations of power (energy), storage capacity, processing power, impairments of wireless communication channels, and the frequent changes of location and t...

The (sodium -Ipotassium)-activated adenosine triphosphatase (NaK ATPase) in Lubrol extracts of NaI-treated bovine brain microsomes has been purified 30 to 50 times over that in the microsomes by salt and isoelectric precipitation, zonal centrifugation, and a new ammonium sulfate fractionation procedure. The final step in the purification procedure renders the NaK ATPase insoluble. The partially...

Introduction: Nakhlites are augite-rich cumulate rocks with variable amounts of olivine and groundmass plus minor Fe, Ti oxides [e.g., 1]. Our previous studies revealed that nakhlites showed correlated petrography and mineralogy that could be explained by different locations (burial depths) in a common cooling cumulate pile [e.g., 2]. We so far analyzed six of the seven currently known nakhlite...

1. Introduction Vowel harmony is a requirement by which vowels in a certain domain agree in one or more phonetic features. 1 In Hungarian, the feature subject to harmony is the horizontal position of the tongue ([±back]). In many Hungarian roots, vowels in a word are either all front or all back, as in öröm 'joy', város 'city' (umlaut denotes front round vowels, and acute accent denotes length)...
