Background: The present study was designed to assess the effect of Mg, Zn, vitamin C and E supplements on microalbuminuria and urinary albumin excretion and N-acetyl-β-D-glucosaminidase activity (βNAG) in type 2 diabetic patients. Materials and methods: In a randomized, double-blind, placebo controlled clinical trial, 69 type 2 diabetic patients were randomly divided into four groups and recei...
A study was conducted to evaluate the effect of vermicompost and nitrogen (N) on growth, nutrient concentration and uptake of N, phosphorus (P), potassium (K), iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) in sunflower shoots as a factorial experiment arranged in completely randomized design (CRD) with three replications under greenhouse conditions. Treatments included three levels of v...
Although the concentration of N-acetylaspartate (NAA) is often used as a neuronal integrity marker, its normal temporal variations are not well documented. To assess them over the 1-2 year periods of typical clinical trials, the whole-brain NAA concentration was measured longitudinally, over 4 years, in a cohort of healthy young adults. No significant change (adjusted for both sex and age) was ...
We report the result of some growth and annealing techniques in the preparation of n and p-PbTe. PbTe has been grown which is intrinsic at room temperature. Maximums mobilities of 4.7 X 106 and 2.8 X 106 cm2/V X sec have been observed in n andp materials, respectively.
BACKGROUND All randomized controlled trials of N-acetylcysteine (NAC) in contrast media-induced nephropathy used creatinine as a marker of renal function. However, it has been suggested that NAC may lower plasma creatinine levels independent of any effects on glomerular filtration rate (GFR). METHODS At a tertiary hospital 110 cardiac surgical patients were randomly allocated to peri-operativ...
Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewaterwith high ammonium concentration or low C/N ratio. In this study, the effect of dissolved oxygen (DO)and influent ratio of chemical oxygen demand to nitrogen (COD/N) ratio on biological nitrogen removal fromsynthetic wastewater was investigated. Experiments were c...
Effects of nutrient solutions on quantitative and qualitative indices of tulip (Tulipa gesneriana cv. Apricot parrot) were studied in a completely randomized design with 5 nutrient solutions, 4 experimental units and 3 replications. Plants were fed with five nutrient solutions (S1, S2, S3, S4 and S5) having NH4+-N/total N ratios of 0, 0.038, 0.074, 0.11 and 0.14, respectively. All nutrient solu...
In order to investigate the effect of form of nitrogen (N) [ammonium (NH4) and nitrate (NO3)] and calcium (Ca) levels of nutrition solution on quantitative and qualitative yield of cut rose flower (Rosa hybrida L.), cv. Vendentta, in soilless culture condition, an experiment was conducted in greenhouse of the National Ornamental Plants Research Station of Mahallat. The experiment was factorial,...
Salinity plays an important role in the reduction of tomato growth, especially in arid and semi-arid regions. Nitrogen (N) may increase tomato tolerance to salt stress by increasing plant growth. In order to investigate the interaction effect of salinity and nitrogen on tomato growth, fruit quality, and micronutrient concentration in tomato plants, a hydroponic experiment was conducted in a com...
