Hypothermic potassium cardioplegia is now commonly used to protect the myocardium during surgically induced ischemia. Because the potassium-related membrane depolarization has been shown to increase calcium influx, we undertook this study to define the effects of varying the calcium content in hyperkalemic perfusates and the effects of using magnesium instead of or in addition to potassium as t...

In order to assess the effects of different pesticides on nutrient levels of rice, three pesticides (Diazinon, Tricyclazole and Butachlor) which are commonly used in paddy fields in Iran were selected in a randomized complete block with 3 replicates in field condition. The result indicated that the impact of different pesticides on total protein and nitrogen, phosphorus and potassium ...

Although phosphorus has long been considered an important factor in the growth of diverse biota such as bacteria, algae, and zooplankton, insect nutrition has classically focused on dietary protein and energy content. However, research in elemental stoichiometry has suggested that primary producer biomass has similar N:P ratios in aquatic and terrestrial systems, and phosphorus-rich herbivores ...

In this study, the prediction of Thymus kotschyanus habitat distribution was investigated using two methods of generalized additive regression model (GAM) and Boosted regression trees (BRT) in central part of Taleghan rangelands. Data on vegetation and habitat factors such as topography, climate, geology and soil were collected. For data preparation, samples were taken from the field to record ...

Considering the increasing rice consumption in the world and also the excessive application of pesticides to increase production, an experiment was conducted to determine the pesticide residues and their effects on nitrogen, potassium and phosphorus content of Hashemi, Khazar and Gohar (SA13) rice cultivars, in a factorial design at randomized complete block design with three replications. In t...

This study is aimed to investigate the spatial variation of soil macronutrients such as phosphorus, potassium and organic matter using different methods of Geostatistics and Geostatistical method combined with Fuzzy logic to estimate the values of this element to provide a spatial distribution map for the proper distribution of fertilizer in the plain of Uremia. Spatial variations in soil nutri...

BACKGROUND AND OBJECTIVES Epidemiologic studies show an association between higher predialysis serum phosphorus and increased death risk in maintenance hemodialysis (MHD) patients. The hypothesis that higher dietary phosphorus intake and higher phosphorus content per gram of dietary protein intake are each associated with increased mortality in MHD patients was examined. DESIGN, SETTING, PART...
