چکیده

A simple, rapid, selective and sensitive analytical method by HPLC with UV detection was developed for the quantification of carbamazepine, phenobarbital and phenytoin in only 0.2 mL of plasma. A C18 column (150 x 3.9 mm, 4 micra) using a binary mobile phase consisting of water and acetonitrile (70:30, v/v) at a flow rate of 0.5 mL/min were proposed. Validation of the analytical method showed a good linearity (0.3 to 20.0 mg/L for CBZ, 0.9 to 60.0 mg/L for PB and 0.6 to 40.0 mg/L for PHT), high sensitivity (LOQ: 0.3, 0.9 and 0.6 mg/L respectively). The method was applied for drug monitoring of antiepileptic drugs (AED) in 27 patients with epilepsy under polytherapy.

Se ha desarrollado un método analítico simple, rápido, selectivo y sensible por HPLC con detección ultravioleta para la cuantificación de carbamazepina, fenobarbital y fenitoína en sólo 0,2 mL de plasma. Se utilizó una columna C18 (150 x 3.9 cm, 4 micras) usando una fase móvil binaria constituida por agua y acetonitrilo (70:30 v/v) a una velocidad de flujo de 0,5 mL/min. La validación del método analítico mostró buena linearidad (0,3 a 20,0 mg/mL para CBZ, 0,9 a 60,0 mg/L para PB y 0,6 a 40,0 mg/L PHT), alta sensibilidad (LOQ: 0,3, 0,9 y 0,6 mg/L, respectivamente). El método fue aplicado para el monitoreo terapéutico de drogas en 27 pacientes epilépticos sometidos a politerapia.

Regulation of AMP-activated protein kinase by multisite phosphorylation in response to agents that elevate cellular cAMP.

The AMP-activated protein kinase (AMPK) and cAMP signaling systems are both key regulators of cellular metabolism. In this study, we show that AMPK activity is attenuated in response to cAMP-elevating agents through modulation of at least two of its alpha subunit phosphorylation sites, viz. alpha-Thr(172) and alpha1-Ser(485)/alpha2-Ser(491), in the clonal beta-cell line INS-1 as well as in mous...

Activation of cardiac AMP-activated protein kinase by LKB1 expression or chemical hypoxia is blunted by increased Akt activity.

AMP-activated protein kinase (AMPK) plays a major role in the regulation of cardiac energy substrate utilization and can be negatively regulated by Akt activation in the heart. It has recently been shown that Akt directly phosphorylates AMPKalpha(1)/alpha(2) on Ser(485/491) in vitro and prevents the AMPK kinase (AMPKK) LKB1 from phosphorylating AMPKalpha at its primary activation site, Thr(172)...

Differential AMPK phosphorylation sites associated with phenylephrine vs. antihypertrophic effects of adenosine agonists in neonatal rat ventricular myocytes.

Stimulation of cardiac AMP-activated protein kinase (AMPK) has been demonstrated in both prohypertrophic and antihypertrophic settings, although the reasons for such discrepant results are not well understood. We determined how AMPK is regulated in response to phenylephrine-induced cardiomyocyte hypertrophy and assessed whether AMPK activity may be a factor underlying the antihypertrophic effec...

One role is to separate different cell groups, for example the differentiating cells of a leaf primordium from the pluripotent cells of the apical meristem. Boundary zones are also established during compound...
