Opis:
The purpose of this paper is to describe the versatility of queuing network systems for modelling vehicular traffic flows in road systems. These techniques are applicable in a simulation context because of the complexity of the resulting models, which can not be solved by mathematical analytical solvers. Moreover, these techniques can be used to model and simulate the behaviour of an automatic control system of vehicular flow in the same frame.

Opis:
The aim of this study was to determine the pharmacokinetics of tramadol and its main metabolites after IV and IM injections. The pharmacokinetic cross-over study was carried out on 6 healthy male beagle dogs. Tramadol was administered by intravenous (IV) and intramuscular (IM) injection at 4 mg/kg. Tramadol and its main metabolites O-desmethyl-tramadol (M1), N-,N-didesmethyl-tramadol (M2) and N-,O-didesmethyl-tramadol (M5) concentrations were measured in plasma samples by a HPLC coupled with fluorimetric detection; pharmacokinetic evaluations were carried out with a compartmental and non-compartmental model for tramadol and its metabolites, respectively. The bioavailability of the drug, ranging between 84-102% (mean 92%), was within the generally accepted values for a positive bioequivalence decision of (80-125%). After the IM injection the mean plasma drug concentration peak was reached after a Tmax of 0.34 h with a Cmax of 2.52 μg/mL. No therapeutic relevant differences were observed between IM and IV administration. The minimal effective plasma concentration was reached after a few minutes and maintained for about 6-7 h in both administrations. M1 plasma concentration was low and the amounts of the other metabolites produced were analogous in both routes of administration. In conclusion, tramadol was rapidly and almost completely absorbed after IM administration and its systemic availability was equivalent to the IV injection. The different onset time and duration of action observed were very small and probably therapeutically irrelevant. The IM injection is a useful alternative to IV injection in the dog.

Opis:
Irbesartan (Irb) is an angiotensin II type 1 receptor antagonist widely used in humans to treat hypertension. Age-related diseases such as hypertension are increasingly being diagnosed in dogs and there is the need for new drugs. The PK/PD of Irb was tested in Beagle dogs. Ten healthy Beagles were orally administered two dose rates (2 and 5 mg/kg), according to a cross over study design. Blood collections for PK analysis and systolic blood pressure (SBP), heart and respiratory rate, mucous membranes colour, capillary refill time and temperature evaluations were performed at scheduled intervals. The drug plasma concentration was dose dependent. The dogs administered 5 mg/kg showed a significant reduction in SBP, while in those receiving 2 mg/kg, this parameter was minimally affected. A counter clockwise hysteresis showed no direct correlation between SBP and plasma concentrations. The minimum effective concentration was theorized to be within the range 550-800 ng/mL. Although further studies are necessary, 5 mg/kg seems to be the more appropriate dose to obtain a hypotensive effect in Beagle dogs.

Opis:
The main purpose of this paper is to show that David Gale's result (1960, Lemma 9.3 on sensitivity in linear programming) is not generally valid. In this lemma, additional assumptions, that are instead required, are not made. We give some correct versions of the above mentioned lemma, and with these an elementary proof of the Gale-Samuelson nonsubstitution theorem.

Opis:
Introduction Research into work reintegration following invasive cardiac procedures is limited. The aim of this prospective study was to explore predictors of job satisfaction among cardiac patients who have returned to work after cardiac rehabilitation (CR). Material and methods The study population consisted of 90 cardiac patients who have recently been treated with coronary angioplasty or heart surgery. They were evaluated during their CR and 12 months after the discharge using validated self-report questionnaires measuring job satisfaction, work stress-related factors, emotional distress and illness perception. Information on socio-demographic, medical and occupational factors has also been collected. Results After adjusting for demographic, occupational and medical variables, baseline job satisfaction (p < 0.001), depression (p < 0.01) and ambition (p < 0.05) turned out to be independent, significant predictors of job satisfaction following return to work (RTW). Patients who had a partial RTW were more satisfied with their job than those who had a full RTW, controlling for baseline job satisfaction. Conclusions These findings recommend an early assessment of patients’ psychosocial work environment and emotional distress, with particular emphasis on job satisfaction and depressive symptoms, in order to promote satisfying and healthy RTW after cardiac interventions.
