AIMS Beta-adrenergic augmentation of Ca(2+) sparks and cardiac contractility has been functionally linked to phosphorylation-dependent dissociation of FK506 binding protein 12.6 (FKBP12.6) regulatory proteins from ryanodine receptors subtype 2 (RYR2). We used FKBP12.6 null mice to test the extent to which the dissociation of FKBP12.6 affects Ca(2+) sparks and mediates the inotropic action of is...

BACKGROUND Preventive child health care is well suited for the early detection of parenting and developmental problems. However, as far as the younger age group is concerned, there are no validated early detection instruments which cover both the child and its environment. Therefore, we have developed a broad-scope structured interview which assesses parents' concerns and their need for support...

Recently, Spark as data processing engine, gained huge popularity because of better performance in terms of the speed. Developers of Spark claim that it may outperform Hadoop MapReduce in 100 times in memory and 10 times on disk [1]. This paper outlines which innovations improved speed and how. In order to investigate improvements, I analysed technical documentation, which is available, since b...

The efficiencies of methods employed in solution of building simulation models are considered and compared by means of benchmark testing. Direct comparisons between the Simulation Problem Analysis and Research Kernel (SPARK) and the HVACSIM+ programs are presented, as are results for SPARK versus conventional and sparse matrix methods. An indirect comparison between SPARK and the IDA program is...

Abstract The highest loads on the elements of crank–piston system internal combustion engine occur during phase which takes place successively in individual cylinders. Smaller, but also significant, beyond this when dynamic forces begin to play a dominant role. latter depends degree wear components. aim article was analyze stresses model stand for testing phenomena an operating without process....

AIMS: β-adrenergic augmentation of Ca 2+ sparks and cardiac contractility has been functionally linked to phosphorylation–dependent dissociation of FK506 binding protein 12.6 (FKBP12.6) regulatory proteins from ryanodine receptors subtype 2 (RYR2). We used FKBP12.6 null mice to test the extent to which the dissociation of FKBP12.6 affects Ca 2+ sparks and mediates the inotropic action of isopro...

Recent research suggests that the diastolic ryanodine-receptor-mediated release of Ca(2+) (J(leak)) from the sarcoplasmic reticulum of ventricular myocytes occurs in spark and nonspark forms. Further information about the role(s) of these release manifestations is scarce, however. This study addresses whether the fraction of spark-mediated J(leak) increases due to β-adrenergic stimulation. Conf...
