Gel filtration of the 40,000 rpm supernatant fraction of a homogenate of rat cerebral cortex on a Sepharose 6B column yielded two fractions: fraction II with the "Ca(2+) plus Mg(2+)-dependent" phosphodiesterase activity and fraction III containing its modulator. The activity of fraction II was stimulated by micromolar concentrations of Ca(2+) and the modulator when present together; the modulat...

in the present work, the effect of milk supplementation on viability of yogurt bacteria (streptococcus thermophilus and lactobacillus delbrueckii subsp. bulgaricus) and probiotic bacteria (lactobacillus acidophilus and bifidobacteria) was studied during yogurt manufacture and thirty three days storage. incubation time to reach ph value of 4.5 was greatly affected by the addition of casein fract...

In quantitative functional neuroimaging with positron emission tomography (PET) and magnetic resonance imaging (MRI), cerebral blood volume (CBV) and its three components, arterial, capillary, and venous blood volumes are important factors. The arterial fraction for systemic circulation of the whole body has been reported to be 20-30%, but there is no report of this fraction in the brain. In th...

Distributions of the largest eigenvalues of Wishart covariance matrices corresponding to the large size data matrices are studied in this paper by reviewing the most recent results on this topic. Special attention is paid to the corresponding asymptotic laws – Tracy-Widom distributions, and their realizations in S-Plus. A further look at the practical aspects of the results studied in the paper...
