[Hypertensive disease and metabolic syndrome: application of metoprolol].

The aim of this work was to study effects of metoprolol on structural and functional characteristics of left ventricle (LV), cerebral circulation (CC), microcirculation (MC), lipid spectrum, rheologic and viscous properties of blood in patients with grade II-III hypertensive disease (HD) and metabolic syndrome. 65 patients in this condition (ESH/ESC, 2007) were given metoprolol (100-150 mg/d) and indapamide (1.5 mg/d) for 6 months.

Enhanced Cd2+ -selective root-tonoplast-transport in tobaccos expressing Arabidopsis cation exchangers.

Several Arabidopsis CAtion eXchangers (CAXs) encode tonoplast-localized transporters that appear to be major contributors to vacuolar accumulation/sequestration of cadmium (Cd(2+)), an undesirable pollutant ion that occurs in man largely as a result of dietary consumption of aerial tissues of food plants. But, ion-selectivity of individual CAX transporter types remains largely unknown. Here, we transformed Nicotiana tabacum with several CAX genes driven by the Cauliflower Mosaic Virus (CaMV) 35S promoter and monitored divalent cation transport in root-tonoplast vesicles from these plants in order to select particular CAX genes directing high Cd(2+) antiporter activity in root tonoplast.

[Effect of eprosartan on microcirculation and blood rheology in patients with hypertensive disease].

The use of eprosartan (600-1200 mg/day for 4 weeks) in 28 patients with stage II hypertensive disease was associated with improvement of parameters of microcirculation and blood rheology.

[Effect of eprosartan on left ventricular diastolic function and cerebral hemodynamics in patients with hypertension].

Eprosartan (600-1200 mg/day) was given for 4 weeks to 28 patients aged 32-62 years with stage II-III hypertension (WHO, 1999). Left ventricular diastolic function and cerebral blood flow were assessed by echocardiography and ultrasound dopplerography. Treatment with eprosartan was associated with improvements of impaired left ventricular diastolic function, structural and functional state of the heart, venous outflow from cerebral vessels, and restoration of unpaired autoregulation of cerebral blood flow.

Tris Is a Competitive Inhibitor of K+ Activation of the Vacuolar H+-Pumping Pyrophosphatase.

The effects of a range of commonly used pH buffers on the hydrolytic activity of the plant vacuolar H+-transporting inorganic pyrophosphatase (V-PPase) from mung bean (Vigna radiata L.) hypocotyls were tested. All of the buffers inhibited K+ stimulation of the V-PPase, and the degree of inhibition was dependent on the concentrations of both the buffer and K+.
