The concentrations of essential elements in the milk of Croatian Coldblood mares and LittoralDinaric donkey were measured. The mean element contents in horse milk were (mg/kg): Ca 687.1, Mg 72.1, K 637.7, Na 143.5, Cu 0.126, Fe 0.235, Se 0.01, Zn 2.06, Mn<0.01. In donkey milk, the mean element contents were (mg/kg): Ca 815.4, Mg 80.8, K 887.7, Na 217.6, Cu 0.027, Fe 0.196, Zn 2.36, Mn 0.016. In...

tain low (Mg )i in cytotrophoblast cells. In addition (Mg )i is acutely regulated by (Mg 2 )o. Because placental trophoblasts are sites of maternal–fetal ion exchange, and (Mg )o is altered in preeclampsia, derangements in or modulation of this exchanger may contribute to complications of pregnancy such as pregnancy-induced hypertension, preeclampsia, and preterm labor. If a Na /Mg antiporter i...

Recent data in the literature support the role of nicotinamide (NA) as a pharmacologic agent that stimulates pancreatic beta-cells to produce insulin in vitro. There are data showing that carbon nanotubes may be useful in initiating and maintaining cellular metabolic responses. This study shows that administration of multiwalled carbon nanotubes (MWCNTs) functionalized with nicotinamide (NA-MWC...

Microsomes prepared from electric organ of Electrophorus electricus contain, in addition to a sodiumand potassiumactivated adenosine triphosphatase, two different ATP-ADP transphosphorylases; one requires only magnesium, while the other requires Mg++ + Na+. The Mg++-activated nucleotide exchange is nonspecific with respect to substrates and is probably unrelated to the highly specific Na+-K+ATP...

Basolateral Mg / Na exchange regulates apical nonselective cation channel in sheep rumen epithelium via cytosolic Mg . Am J Physiol Gastrointest Liver Physiol 288: G630–G645, 2005. First published November 18, 2004; doi:10.1152/ajpgi.00275.2004.—High potassium diets lead to an inverse regulation of s...

Salt stress is one of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. A greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (Bamiand Hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mM NaCl) at the College of Agriculture,Shiraz University, Shiraz, Iran in 2008. Plant dry weig...

The effects of supplemental potassium were studied on growth, ion concentration and anatomical parameters in one year old olive trees, Olea europaea L., grown in sand culture in greenhouse at different levels of NaCl for 80 days. The experiments were conducted in a completely randomized design as a factorial. Factor one was salinity (0, 40 or 80 mM NaCl) and the second factor was potassium leve...

Introduction: To assess the salivary composition of proteins and minerals in smokers compared with non-smokers.   Materials and Methods: In this study we compared the total protein and Ca, Na, K, Mg, Pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years.   Results: Fifty-nine participants were evaluated. The mean age was 33.14±5.32 years among smo...

The pharmacokinetics of the hepatobiliary transport of an anionic drug, 7,8-dihydro-5-[(E)-[[a-(3-pyridyl)-benzylidene]aminooxy]ethyl]-1- naphthyloxy]acetic acid (ONO-1301), a new prostaglandin (PG) I2 receptor agonist, was investigated in rats. During intravenous infusion of this compound, the drug concentrations in arterial blood, hepatic vein and liver and the biliary excretion rate were mea...

one of the main aims of water resource planners and managers is to estimate and predict the parameters of groundwater quality so that they can make managerial decisions. in this regard, there have many models developed, proposing better management in order to maintain water quality. most of these models require input parameters that are either hardly available or time-consuming and expensive to...
