In this technical report we define an operational net semantics for the stochastic process algebra MPA based on generalized stochastic Petri nets. As a consequence of the definition of such a semantics, we present an interesting modeling technique for concurrent systems which is based on MPA. 1.

To improve the extraction of polycyclic aromatic hydrocarbons (PAHs) from sediment samples, we optimized the conditions of pressurized liquid extraction (PLE). The yields increased as the extraction temperature increased from 100 to 190 degrees C, but the effect of increasing pressure (from 15 to 20 MPa) was small. Parameters of 190 degrees C and 20 MPa, near the maximum of the equipment, gave ...

The conjugated equine estrogens-only arm of the Women's Health Initiative trial, showing a trend toward protection from heart disease as opposed to women receiving also medroxyprogesterone acetate (MPA), strengthens the debate on the cardiovascular effects of progestins. We compared the effects of progesterone (P) or MPA on the synthesis of nitric oxide and on the expression of leukocyte adhesi...

The aim of the current study was to investigate the relationship between social anxiety and musical performance anxiety (MPA). Previous literature has reported mixed results concerning correlations between social anxiety and MPA. To better describe overlapping and unique features in comparison with social anxiety disorder may introduce new options for treatment. The aim of the current study was...

Shearing stress of wheat stalk was measured for four moisture content levels (15, 25, 35 and 45%, w.b.), three cutting heights (100, 200 and 300 mm), two types of cutting knives, smooth and serrated edge and three blades oblique angle (0, 15 and 30 deg.). The results of data analysis showed that the shearing stress of wheat stems decreased as the moisture content decreased. The shearing force o...

Changes of mycophenolic acid (MPA) pharmacokinetics with aging were investigated in rats. We also compared the effect of concomitant amoxicillin/clavulanate combination (CVA/AMPC) on the pharmacokinetics of MPA in 4-week-old and 12-week-old rats (the package insert of CVA/AMPC warns of possible interaction with MPA). Four-week-old rats showed a 1.4-fold higher total body clearance of MPA and a ...

Medroxyprogesterone acetate (MPA) is a synthetic progestin commonly used in hormone replacement therapy (HRT). The aim of this research was to study and compare the effect of progesterone (Pg) and MPA on the regulation of cellular events associated with vascular homeostasis and disease. Platelet adhesion to endothelial cells (ECs), nitric oxide (NO) production, and cell migration were studied u...

Microscopic polyangiitis (MPA) is an ANCA-associated vasculitis that affects small vessels, especially renal glomeruli. We recently demonstrated that the abnormal formation and impaired degradation of neutrophil extracellular traps (NETs) may be crucially involved in the generation of myeloperoxidase (MPO)-ANCA and subsequent development of MPA. This study assessed the formation and regulation ...

BACKGROUND Mycophenolic acid (MPA) is the active immunosuppressive substance in both mycophenolate mofetil and mycophenolate sodium, and it is widely used after organ transplantation. In women, taking MPA is teratogenic and may also influence spermatogenesis. There is a lack of knowledge regarding outcome of pregnancies fathered by men exposed to MPA. METHODS We compared outcomes in pregnanci...
