Effectiveness and safety of telemedical management in uncomplicated urinary tract infections.

Uncomplicated urinary tract infections (UUTI) in women are frequent reasons for consultations in general practice. We evaluated the effectiveness and safety of telemedical management at a telemedicine centre in Switzerland. Management followed evidence-based protocols, including teleprescription of an antibiotic.

Differential involvement of 3', 5'-cyclic adenosine monophosphate-dependent protein kinase in regulation of Fos and tyrosine hydroxylase expression in the heart after naloxone induced morphine withdrawal.

We previously demonstrated that morphine withdrawal induced hyperactivity of the heart by the activation of noradrenergic pathways innervating the left and right ventricle, as evaluated by noradrenaline (NA) turnover and Fos expression. We investigated whether cAMP-dependent protein kinase (PKA) plays a role in this process by estimating changes in PKA immunoreactivity and the influence of inhibitor of PKA on Fos protein expression, tyrosine hydroxylase (TH) immunoreactivity levels and NA turnover in the left and right ventricle. Dependence on morphine was induced by a 7-day s.

Role of PKC in regulation of Fos and TH expression after naloxone induced morphine withdrawal in the heart.

We previously demonstrated that morphine withdrawal induced hyperactivity of the heart by activation of noradrenergic pathways innervating the left and right ventricle, as evaluated by noradrenaline (NA) turnover and Fos expression. The present study was designed to investigate the role of protein kinase C (PKC) in this process, by estimating whether pharmacological inhibition of PKC would attenuate morphine withdrawal induced Fos expression and changes in tyrosine hydroxylase (TH) immunoreactivity levels and NA turnover in the left and right ventricle. Dependence on morphine was induced on day 8 by an injection of naloxone.

Alterations in protein kinase A and different protein kinase C isoforms in the heart during morphine withdrawal.

The present study was designed to investigate the possible changes of protein kinase A (PKA) and different isoforms of protein kinase C (PKC): PKC alpha, PKC delta and PKC zeta after naloxone induced morphine withdrawal in the heart. Male rats were implanted with placebo (naïve) or morphine (tolerant/dependent) pellets for 7 days. On day 8 rats received saline s.

Inhibition of protein kinase C but not protein kinase A attenuates morphine withdrawal excitation of rat hypothalamus-pituitary-adrenal axis.

Our previous studies have shown an enhanced activity of the hypothalamus-pituitary-adrenocortical axis response in rats withdrawn from morphine, which results from an increase in the hypothalamic paraventricular nucleus noradrenergic activity that is dependent on alpha-adrenoceptor activation. The first objective of this work was to examine the effect of protein kinase A (PKA) and protein kinase C (PKC) inhibitors on morphine withdrawal-induced changes in corticosterone release (an index of the hypothalamus-pituitary-adrenocortical axis activity) and in catecholaminergic turnover in the paraventricular nucleus. Plasma corticosterone levels as well as the concentration of noradrenaline, 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG), dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) in the paraventricular nucleus were determined.
