Radioiodinated m-iodobenzylguanidine (MIBG), a scintigraphic agent used in the detection of human pheochromocytomas, is thought to utilize the same uptake and retention mechanism(s) as norepinephrine (NE). Using primary cultures from 16 human pheochromocytomas, we compared the uptake of MIBG to that of NE. Two different uptake systems were identified. Both NE and MIBG were taken up by a sodium-...
Two commercial methods are used for the production of strontium carbonate:1) Direct conversion of Celsetite to strontium carbonate by hot sodium carbonate,2) Carbothermic reduction of celestite with coal followed by water leaching of strontium sulfide(SrS) and its conversion to strontium carbonate.The present study has been made on the carbothermic reduction of celestite ores of Varamin (Iran) ...
In this work, a stable NiFe2O4 paraffin based ferrofluid was prepared via high energy milling. The rheological properties of ferrofluid were studied. Bingham plastic, HerschelBulkley and Casson models were used to evaluate the shear stress-shear rate dependency. The ferrofluid exhibited a shear thinning behaviour for all studied magnetic field. The magneto-viscous effect and thixotropy of...
A novel investigation of the nature of intermittency in incompressible, homogeneous, and isotropic turbulence is performed by a numerical study of the Navier-Stokes equations constrained on a fractal Fourier set. The robustness of the energy transfer and of the vortex stretching mechanisms is tested by changing the fractal dimension D from the original three dimensional case to a strongly decim...
Mitochondrial Ca(2+) uniporter is the primary influx pathway for Ca(2+) into respiring mitochondria, and hence plays a key role in mitochondrial Ca(2+) homeostasis. Though the mechanism of extra-matrix Ca(2+) dependency of mitochondrial Ca(2+) uptake has been well characterized both experimentally and mathematically, the mechanism of membrane potential (ΔΨ) dependency of mitochondrial Ca(2+) up...
The sustainable development and energy security are currently the priority challenges for the European Union countries. The sustainable and stable development of European economies is closely dependent on the stable access to energy resources. The constant increase of the demand for electricity requires long-term planning of the common European policy. The aim of the article is to analyse the f...
In soil mechanics, student's models are classified as simple models that teach us unexplained elements of behaviour; an example is the Cam clay constitutive models of critical state soil mechanics (CSSM). 'Engineer's models' are models that elaborate the theory to fit more behavioural trends; this is usually done by adding fitting parameters to the student's models. Can currently unexplained be...
WHICH UNIQUE INSIGHTS can be gained from the investigations of the physiology of the growing child? Are there pragmatic outcomes to research in children’s exercise science that bear specific utility to this age group or to their future life? What importance do exercise responses in youth bear to our understanding of the nature of human movement? The reviews appearing in this highlighted topic s...
The goal of the European energy policy is to achieve climate neutrality. long-term strategies various countries include additional targets such as diversification sources, maintenance security supply, and reduction import dependency. When optimizing systems, these strategic are often only considered in a rudimentary manner thus, understanding corresponding interdependencies lacking. Moreover, h...
