Introduction: We investigated the role of ATP-sensitive potassium channels and L-type calcium channels in morphine-induced hyperalgesia after nociceptive sensitization. Methods: We used a hotplate apparatus to assess pain behavior in male NMRI mice. Nociceptive sensitization was induced by three days injection of morphine and five days of drug free. On day 9 of the schedule, pain behavior te...

Measurements of partial-body calcium by in vivo neutron activation analysis have been carried out on normal and osteoporotic subjects. Based on measurements on 16 normal subjects (volunteers less than 55 years of age), a calcium index has been established that takes into account variation in skeletal frame size. On the basis of this index, all osteoporotic patients have bone mineral content les...

The effects of sodium pump inhibition produced by exposure to the cardiac glycosides, ouabain or dihydroouabain, or by reduction in extracellular potassium to 1.0 mM, on contractile state and sodium-calcium exchange were studied in primary monolayer cultures of chick embryo ventricular cells. Ouabain, 10(-6)M, dihydroouabain, 5 X 10(-5)M, and extracellular potassium of 1.0 mM all induced simila...

Background: Synthetic coagulants commonly used for water treatment are associated with undesirable properties, such as inefficacy and toxicity in addition to being expensive. Natural coagulants are considered safe and economical alternatives for developing countries where the plants are abundantly available. Methods: The phytochemical composition and safety of water samples treated with Mang...

training systems and calcium foliar application can improve apple fruits pigmentation by changing mineral compositions. in this study, effect of foliar application of calcium chloride with different concentrations (0, 0.75, 1.5 and 3 g l-1) over 2, 4 and 6 weeks before harvest time on fruit mineral nutrient composition and colour values of apple cvs. gala and delbarestival which trained in thre...
