PARTICIPANTS RATED THE PERCEIVED complexity and melodiousness of fractal (1/f ) tone sequences with specific ß values. Plotting the mean complexity and melodicity ratings against each other and against ß indicated that: (1) a melody’s spectral power density slope ( ß) can be used as an objective measure of its perceived complexity; (2) ß ≈ 1.50 for optimally preferred melodies; (3) perceived co...

The effect of lysophosphatidic acid on the phosphorylation and function of alpha(1b)-adrenoceptors transfected into rat-1 fibroblasts was studied. This phospholipid mitogen increased in a concentration-dependent fashion (EC(50) approximately 50 nM) the phosphorylation of these adrenoceptors. Lysophosphatidic acid-induced alpha(1b)-adrenoceptor phosphorylation was relatively rapid (t(1/2) approx...

Given the broad use of nanostructured crystalline titania films, an environmentally friendly and more sustainable synthesis route is highly desirable. Here, a water-based, low-temperature presented to synthesize foam-like films. A pearl necklace-like nanostructure introduced as tailored morphology via biotemplating with major bovine whey protein ß-lactoglobulin (ß-lg). It shown that crystalliza...

Adrenoceptors [1] belong to class A of the superfamily of G protein coupled receptors (GPCRs) that transduce signals across the cell membrane, thus initiating a variety of intracellular biochemical events. The adrenoceptors subtypes (α1A, α1B and α1D) are of particular therapeutic interest due to their important role in benign prostatic hyperplasia, a medical condition associated with old age.

Saffron essential oil has a pleasant aroma and medicinal activities. However, it is sensible into the environmental condition. Therefore, it should be protected against unwanted changes during storage or processing. Encapsulation is introduced as a process by which liable materials are protected from unwanted changes. In the present study, different ratios (0:100, 25:75, 50:50, 75:25, and 100:0...

Cardiac /S-l adrenoceptors respond to sympathetic nerve stimulation (SNS), but it is not clear that SNS evokes fi-2 adrenoceptor-mediated vasodilation. Sensitivity of B adrenoceptors to catecholamines and to SNS was evaluated in dogs. Norepinephrine (NE) and epinephrine (E) were equipotent vasoconstrictors (femoral artery blood flow or gracilis autoperfusion pressure) before aadrenoceptor block...

This study investigates the incidence of high-salt diet in blood pressures, renal alpha(2)-adrenoceptor subtypes distribution, and gene expression in salt-sensitive (SBH) and salt-resistant (SBN) Sabra rats. Comparisons have been made between SBH and SBN rats submitted to a normal or a high-salt diet for 6 weeks. Only alpha(2)B-adrenoceptors are detected in kidneys of SBH rats, whatever the die...
