OBJECTIVE To test the vasodilatory response of the pulmonary vascular bed in children with pulmonary hypertension. DESIGN Prospective dose response study in which the effects of inhaled nitric oxide (NO) are compared with those of oxygen and intravenous prostacyclin. PATIENTS AND INTERVENTIONS The vasodilator test was performed in 20 patients in whom mean pulmonary artery pressure (PAPm) wa...

OBJECTIVE To evaluate the larvicidal and pupicidal potential of the methanolic extracts from Moringa oleifera (M. oleifera) plant seeds against malarial vector Anopheles stephensi (A. stephensi) mosquitoes at different concentrations (20, 40, 60, 80 and 100 ppm). METHODS M. oleifera was collected from the area of around Bharathiar University, Coimbatore. The dried plant materials were powdere...

OBJECTIVE This study evaluated the effects of three post-brushing mouthwashes containing 0 ppm F, 225 ppm F, and 500 ppm F, respectively, on salivary fluoride retention after brushing with 1450 ppm fluoride (as NaF) toothpaste and rinsing with water immediately after brushing. METHODS In this three-phase, randomized, cross-over study, an ion-specific electrode was used to measure salivary F l...

Two field experiments were carried out in Agricultural Research and Experimental Station, Faculty of Agriculture, Cairo University, Giza, Egypt (2019 2020) to study the response Egyptian cotton cultivars (Giza 92, Giza 94 95) growth, yield fiber properties foliar zinc (Zn) rates (0, 100 200 ppm) nitrogen (N) fertilizers sources; urea (U), ammonium nitrate (AN) sulfate (AS).  Cultivars, N source...

Carotenoids in the peel and the flesh of persimmon fruit were identified, and the contents of carotenoids in the fleshes of 46 different persimmon cultivars were analyzed. The results indicated that 31 specific carotenoids were detected in both cultivars of persimmons, among which nine specific carotenoids were characterized. β-cryptoxanthin was the most abundant carotenoid among all individual...

Banana cultivars--Luvhele (MusaABB), Mabonde (MusaAAA), and Muomva-red (Musa balbisiana) --were characterized for morphological, physicochemical, and antioxidant properties. All three cultivars varied significantly (P < 0.05) in their morphology, pH, titratable acidity and total soluble solids with no significant difference in their ash content. Individual cultivars showed variations in flour s...
