ATP-sensitive potassium (KATP) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. There has been considerable interest in exploring KATP channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. The purpose of this study was to synthesize 3,3,6,6-tet...

abstract mineral weathering is a major source of most essential nutrients including potassium. it is well known that potassium plays an important role in improving the quality of agricultural products and micaceous minerals, as the major source of potassium, are abundant in iranian soils. no information is available on the role of micaceous minerals in supplying k to barley as the second major ...

abstract heated micaceous minerals under different commercial brand names (including vermiculite) are used as culture medium in greenhouses. heating minerals affects the release of elements, such as potassium, by changing their structure. the present study, investigates the ability of alfalfa, as one of the most important fodder around the world, to take up the non-exchangeable and structural p...

abstract a simple and sensitive chemiluminescence (cl) method was developed for direct quantification of oxymorphone, a µ opioid agonist that is approximately 10 times more potent than morphine. in this method potassium permanganate in polyphosphoric acid was used as cl reagent. using this method, oxymorphone can be determined over the concentration ranges 13.5-337.8 ng ml-1 and 0.34-6.76 µg ml...

potassium ferrate has been used as a multi-purpose chemical in treatment of wastewaters. with the formula of k2fe04 it has 3 excellent characters for water treatment, so by using it alone, it would be possible to confine all reactivity, it is essential to prepare ferrate at the point of use. in this study, k2fe04 was synthesized, then it has been employed for chlorine gas with an alkaline solut...

the potassium pools of five major physiographic units of urmia region in western azarbaijan province were studied to investigate the distribution of k forms as a function of clay mineralogy and physiographic units. for this, soil samples from different horizons of ten pedons were selected and analyzed for physiochemical properties, mineralogy of clay fraction, and forms of k. analyses of xrd re...

background: potassium permanganate (pp) is a highly corrosive and deadly agent with a reported lethal dose of 10 g in adults. in this report, successful treatment of a patient poisoned with three times the lethal dose of pp is presented, and effective and early approach to such emergency toxicologic condition is discussed. case presentation:a 24-year-old woman presented to emergency room of our...

Major uses Potassium chloride (KCl) is inorganic salt used for making fertilizers, since the growth of many plants is limited by their potassium intake. Potassium in plants is important for the osmotic and ionic regulation, plays a key role in the water homeostasis and is closely connected with processes involved in the protein synthesis. KCl is also used for the manufacture of potassium hydrox...
