DNA yields ranged from 10-20 mu g (in 100-mu L elution volumes) from all plant material evaluated. The DNA obtained was free of any contaminating proteins, polysaccharides and colored pigments. The extracted genomic DNA was found suitable for restriction digestion and PCR amplification. Our experimental procedure provides an easy, suitable, non-toxic, cheap, and quick process for the amplification of DNA from medical plant tissue.”
“The polarization switching behavior in serially connected ferroelectric Pt/Pb(Zr,Ti)O-3/Pt and paraelectric capacitors with various capacitances was examined using transient

switching current measurements. Provided that a high enough voltage to switch the ferroelectric capacitor was applied to the series capacitor, stable polarization switching was maintained before the applied voltage approached zero, irrespective

of the capacitance of the paraelectric capacitor. For the series AZD8931 capacitor containing a small paraelectric capacitance, the voltage across the paraelectric capacitor was much higher than the coercive voltage of the PZT capacitor, which acted as a field depolarizing PZT capacitor resulting in back-switching when the applied voltage was removed. In contrast, no back-switching occurred in the series capacitor containing a sufficiently large paraelectric capacitance because the voltage across the paraelectric capacitor was smaller than the coercive voltage of the ferroelectric capacitor. The MK-0518 clinical trial effects of the measurement set-up and their implications for various suggested Etomoxir nmr applications are also discussed in detail. This result improves the understanding on the role of passive interfacial layers in metal-ferroelectric-metal capacitors. (C) 2011 American Institute of Physics. [doi:10.1063/1.3597816]“
“Hypertension is particularly prevalent in patients aged >= 65 years, those with a body mass index >= 30

kg m(-2), Blacks and those with type II diabetes. Here we report a prespecified secondary analysis of the efficacy of amlodipine (10 mg day (1)), olmesartan medoxomil (40 mg day (1)), a combination of the two and placebo in these subgroups. Patients were randomized to treatment for 8 weeks. The primary efficacy endpoint was the change from baseline in mean seated diastolic blood pressure (DBP). Secondary efficacy endpoints included the change from baseline in mean seated systolic BP (SBP), proportions of patients achieving BP goal (<140/90 mm Hg or <130/80 mm Hg in patients with diabetes), and the number and percentage of patients achieving a range of BP targets. Safety and tolerability of amlodipine 5 and 10 mg, olmesartan medoxomil 10, 20 and 40 mg, and all possible combinations of the two were also assessed. For each prespecified subgroup, all active treatments resulted in significant BP reductions from baseline (P<0.05).
