We investigated the effects of piperitenone oxide (PO), a major constituent of the essential oil of Mentha x villosa, on the guinea pig ileum. PO (30 to 740 micrograms/ml) relaxed basal tonus without significantly altering the resting membrane potential. In addition, PO relaxed preparations precontracted with either 60 mM K+ or 5 mM tetraethylammonium in a concentration-dependent manner. At con...

Using microtitration method, the relationship between Phenoloxidase activity and the resistance of the diamondback moth Plutella xylostella (Linnaeus) to the novel insecticide butane-fipronil was determined in vitro. After selection of the tenth-generation by butane-fipronil, the resistance of the fourth instar larvae was increased 83.80-fold as compared to the susceptible strain. Phenoloxidase...

The mixed-valent titanium phosphate, Li(2)Ti(2)(PO(4))(3), has been prepared by the reactive halide flux method. The title compound is isostructural with Li(2)TiM(PO(4))(3) (M = Fe, Cr) and Li(2)FeZr(PO(4))(3) and has the same (3) (∞)[Ti(2)(PO(4))(3)](2-) framework as the previously reported Li(3-) (x)M(2)(PO(4))(3) phases. The framework is built up from corner-sharing TiO(6) octa-hedra and PO(...

The incommensurately modulated structure of K(3)In(PO(4))(2) has been solved and refined. The origin of the modulation relates to the ordering of K cations within the hexagonal close packing of the PO(4) anions. The driving forces for the modulation of the other cations are In-P and K-P interactions. The modulation of O atoms of rigid PO(4) units follows the cations in order to stabilize the In...

OBJECTIVE To determine the accuracy of heart rate obtained by pulse oximetry (HR(PO)) relative to HR obtained by 3-lead electrocardiography (HR(ECG)) in newborn infants in the delivery room. STUDY DESIGN Immediately after birth, a preductal PO sensor and ECG leads were applied. PO and ECG monitor displays were recorded by a video camera. Two investigators reviewed the videos. Every two second...

We have previously purified a transcription factor, PO-B, whose DNA binding capacity is increased by dephosphorylation and which contributes significantly to the basal transcription of genes such as pro-opiomelanocortin (Wellstein A., et al., J. Biol. Chem., 266: 12234-12241, 1991). In the present study, we describe several new properties of PO-B which suggest that the function of this transcri...

The title compound, K(2)Sm(MoO(4))(PO(4)), has been prepared under atmospheric conditions using a high temperature solution growth (HTSG) method. The structure of K(2)Sm(MoO(4))(PO(4)) is isotypic with other A(2)M(MoO(4))(PO(4)) compounds, where A = Na or K, and M = trivalent rare earth cation. It can be described as being built up from two-dimensional anionic layers with composition [Sm(MoO(4)...

Structured Abstract Purpose Several organizations choose a process-oriented organizational design as a source for competitive advantage. In this paper, we explore empirically the relationship between process orientation (PO) and firm performance. We consider PO as a multidimensional construct and examine how its underlying dimensions impact different aspects of organizational performance. Desig...

The objective of the present study was to evaluate the anxiolytic and antidepressant activities of methanol extract of Aegle marmelos (AM) leaves as well as its interaction with conventional anxiolytic and antidepressant drugs using elevated plus maze and tail suspension test in mice. Albino mice were treated with AM (75, 150 and 300 mg/kg, po), imipramine (20 mg/kg, po), fluoxetine (20 mg/kg, ...
