cept can serve as a basis for identifying subgroups that are in need of programmatic action. Unmet need rises as more women would like to control their fertility but for various reasons are unable to do so, and it falls as more start practicing contraception. However, high levels of unmet need in a country do not necessarily reflect program failure, nor do low levels always indicate program suc...

Contractions of vas deferentia induced by KCI or field stimulation were not different between mature and old rats. The effect of trypsin or BaCl2 but not bradykinin or carbachol on contraction induced by field stimulation was significantly different between mature and old rats. The increase of twitching contractions by trypsin may be due to its effect on presynaptic alpha-adrenoceptors. Trypsin...

Isothermal calorimetric titration of 18-crown-6 ether with BaCl2 in pure aqueous solution over the temperature range 7-40 degrees C gives precise binding constants and enthalpy changes. Nonlinear least-squares fitting of the binding constants to the integrated van't Hoff equation, including a temperature-independent change in heat capacity, leads to van't Hoff enthalpies that differ significant...

BACKGROUND The aim of this study was to compare the effects of nebivolol and telmisartan on left ventricular mass (LVM) and midwall mechanics in mild-to-moderate hypertension. METHODS A total of 40 patients with mild-to-moderate hypertension were randomized to receive either nebivolol (2.5 to 5.0 mg/day) or telmisartan (40 to 80 mg/day) to achieve a target diastolic blood pressure of <90 mm H...
